[DotA2] Holy Sword
Chapter 7 Investigating the Guards
[-]th Battle Scout Guard
Now that they were very close to the Range Rover platform, both of them unknowingly quickened their pace.Especially An Rongyu, although he was born and bred in Shang'an and had been to Lancui Mountain many times, he had never set foot on this winding and steep path.
As if he suddenly remembered something, Yan Che asked: "Song list, do you like it?" After speaking, he felt a little embarrassed, "They are all songs I like, I'm afraid you won't like to listen to them."
"I like it! I like every word." Almost without thinking about it at all, An Rong and nodded fiercely.
Most of the songs in the playlist are English songs, and the style can be said to be very single-sad spring and sad autumn.The lyrics are gloomy and the tune is even more resentful and admirable, which sounds particularly melancholy.An Ronghe didn't have the habit of listening to music before, he just walked by and heard the subwoofers in the streets and alleys, so he didn't have a favorite singer or song type.
Yan Che's playlist had opened the door to a new world for him. Thinking that this was Yan Che's favorite song, no matter how sad the lyrics and tune, he would always enjoy listening to it—he always wanted to find a chance to sing it to Yan Che of.
Seeing the opportunity came, he was eager to try it, turned his head and said to Yan Che: "Brother, how about I sing it to you?"
Yan Che agreed with embarrassment. Although An Ronghe had no idea about his own singing level, he was inexplicably confident at the moment, turned on his phone, and played a song.
The soothing and lingering prelude sounded, and he sang along with the music.
"The evening grab sus in the sound wear ebound."
"Wesit and watch the sun moving down."
"It feels so good to ha|ve you around."
"Wish we could stay forever, ha|ve forever now."
An Rongyu heard this song on a night of insomnia. He was half asleep and half awake at the time. When the chorus lingered in his ears, he suddenly woke up with a start.Although I couldn't understand the lyrics directly just by listening, but after opening the software, I couldn't understand it word by word.
From then on, he hoped that Yan Che would have the same intentions as him: the two of them would watch the sunrise and sunset together, enjoy every second of each other's side, and pray to God to stop time and preserve such wonderful time forever.
I don't know if Yan Che noticed the slight shaking of An Rongyu's voice when he sang - he sang with all his heart.Fortunately, his voice and talent were not bad, every word was in tune steadily, coupled with the deep emotion, Yan Che seemed to be dumbfounded, until the end of the music, he didn't say a word.
An Ronghe was still immersed in the lyrics at this moment, and only when he realized his reaction did he feel that his eyes were a little moist.Hastily blinked his eyes a few times, smiled and said to Yan Che: "Brother, did it scare you by being so ugly?"
"No, no, it's very good, I'm fascinated by it." Yan Che seemed to have sorted out his emotions, and both of them returned to normal.
After a few words, the line of sight suddenly opened up, and the dense forest was drilled out. In front of it was an open platform surrounded by a circle of simple wooden piles. It should be set up by the scenic spot to prevent tourists from accidentally falling off the cliff.
I saw that this spacious platform is about 20 meters square, with potholes and broken stones on the surface.Unlike the green onions behind and in front of the eyes, there is no vegetation growing, not even a thin grass.The two walked to the fence and looked down. There were many pine branches growing on the cliff, full of vitality.
Standing at such a height, there is really a sense of majesty and magnificence at a glance.
After eating two bites, Yan Che found a place to camp.Although I have never had such an experience before, but fortunately the design of the tent is simple and clear, and it is very convenient to install. For An Rongyu, it is more fun than tiring.
It was 9 o'clock quietly, and the two sat down lightly. The vast land had sunk into the endless night, and the moonless sky was dotted with countless twinkling stars.
The air on the top of the mountain is clean and transparent, and the scenery near and far is clearly and vividly printed.The stars that are seldom seen in the urban area on weekdays are competing to shine brightly at this moment.
"Pretty, isn't it?" Seeing through the shock from the young man's heart, Yan Che continued, "Although my home is a mountain city, the peaks are only a few hundred meters away, and the view is far worse than here."
"Brother, can you take me to see the starry sky next time?" After hearing the few stories today, An Rongyu was really interested in Yan Che's hometown, and wished he could fly there right away.
Yan Che agreed with a smile, and then introduced the starry sky to him.
"Do you know this spoon-shaped seven stars?" Yan Che planned to start with the simplest one.
"Of course, the Big Dipper. I still know this." The young man actually showed a slight sense of pride, not realizing that this is common sense that even elementary school students know.
"Then do you know what each star is called?" It seemed that he was determined to embarrass An Rongyu.
The young man who was still high-spirited just now really had a "smile gradually disappearing" expression at the moment.
Seemingly satisfied with this reaction, Yan Che said slowly: "Starting from the mouth of the spoon, there are Tianshu, Tianxuan, Tianji, and Tianquan. The next spoon handles are Yuheng, Kaiyang, and Yaoguang."
An Rongyu nodded, "The name sounds nice. It seems that the North Star can be found through the Big Dipper?"
"Well. If you look in the direction of the opening along the line segment formed by the two points Tianshu and Tianxuan, the distance about 5 times the line segment is the North Star."
“1、2、3、4、5……是不是那颗?”少年发现新大陆一般指着一颗在漫天繁星中都丝毫不逊色的亮点。
"Smart. Have you ever seen a time-lapse map of the starry sky?"
"Is it the kind with circles of light?"
Hearing this, Yan Che couldn't hide his smile: "Yes. If you look carefully, you will find that basically the star trails of the northern hemisphere, the one closest to the central dot is Polaris."
Seeing the shocked young man in front of him, his eyes widened and he stared at the shining guiding star, Yan Che continued to ask thoughtfully, "Do you know about precession?"
The expression on the young man's face instantly turned into confusion. He shook his head, waiting for the other party's explanation.
"Precession in astronomy refers to the slow and continuous change in the direction of the rotation axis of a celestial body in space due to the effect of gravity." As if feeling that this explanation was a bit awkward for him, Yan Che thought for a while and continued: " Let’s put it this way, the rotation axis of the earth is regarded as a straight line, and this straight line is not eternal. As time goes by, it draws two cones with opposite ends in space with the center of the earth as the origin. "
While speaking, Yan Che picked up a twig from somewhere, pulled An Ronghe to the outside of the woods not far away, and drew a schematic diagram on the soft ground - two lines perpendicular to each other, the intersection point Mark the origin; pass through the origin and cross the second and fourth quadrants; draw an ellipse parallel to the x-axis at both ends of the line segment, and mark the counterclockwise arrow.
An Rong and nodded thoughtfully, roughly understood.
Yan Che continued to make gestures on this sketch with satisfaction: "This cycle is about 6000 years, causing the vernal equinox to move westward along the ecliptic." He probably felt that the explanation was too deep and meaningless, so he stopped there and returned to the topic just now. "Let's not mention this first, it's a little hard to understand. What I want to say is that because of the precession difference, the Polaris is different in different periods."
The boy's expression turned back to shock. He obviously didn't expect that the Big Dipper, which can be recognized by even an elementary school student, could involve so many mysteries.
"About 4800 years ago, the Polaris at that time was the α star of Draconis; in ancient Greece, it was the β star of Ursa Minor. The Polaris we see now also belongs to the constellation Ursa Minor, which is the α star, and around 2100, this The angle between the first star and the North Pole will be the smallest." Deliberately giving the boy some time to react, Yan Che continued to poke the small hole aimlessly on the ground, "The next North Star will have to wait until Shaowei around the 31st century. Increase by eight."
At that time, not only people will change, but things will no longer be the same.Compared with the vast universe, the lifespan and cognition of human beings are really not worth mentioning.I don't know if there are higher beings on the far side of the galaxy, whether they have already explored the mysteries of the universe, escaped from reincarnation, and will live in love with the one they love for life after life.
Both of them might feel a little desolate, and Yan Che took the lead in comforting him: "Although human life is fleeting, we don't have the opportunity to watch the changes of the North Star, but in this vast starlight, there are also many stars that died hundreds of millions of years ago. A fallen celestial body."
An Rongyu didn't know whether to cry or laugh, he didn't expect Yan Che's consolation to be worse than this - hundreds of millions of years can't be regarded as eternity, for mortals who can't get rid of the fate of death, creating " What is the meaning of the word "forever"?Not to mention competing with the sun and the moon-the sun will burn out in 50 billion years, so is there anything in the universe that can truly be called "eternal"?
Finally realizing that his "comfort" was not helping, Yan Che coughed in embarrassment, and forcefully explained: "Well, in front of celestial bodies, our time is like fireworks, but for those celestial bodies that have passed away many years ago , they can’t see the rich and colorful life of human beings today.”
A cool mountain wind blew by, and the top of the mountain was silent again.An Rongyu believed that this perfect man who was well educated and knew everything probably didn't know how to comfort others.In his heart, this naturally cannot be Yan Che's shortcoming, but it adds a touch of "cute" attribute.
"Brother, let's talk about other stars." An Rongyu has never observed the starry sky. In cities with severe light pollution, the night sky is filled with strange lights of various colors. Occasionally, the moon can be seen. The visibility of the stars is really limited. Layers of pollutants filter overshadowed.This time watching the stars with Yan Che at night, he realized that this kind of thing that can be seen from the head can be so interesting.Yan Che's meticulous explanation made this kind of fun a few more levels.
"Summer Triangle. Did you see that very bright star?" Yan Che pointed to the night sky. Among the countless twinkling bright spots, the brightness of that star was definitely one of the best.
An Rongyu nodded, wondering what kind of asterism this big triangle would be.
"That's Vega, which belongs to the constellation Lyra." After glancing at An Rongyu's reaction, it turned out that this star linked to the protagonist in the eternal love story made people feel extremely cordial. "It is the fifth brightest star in the entire sky and was the North Star around 11500 BC and then around 13700 AD."
"There must be Altair in this big triangle, right? I guess the Milky Way is between them!" An Rongyu reacted quickly, and was complacent about his wit at this time.
"Smart. Vega is also the brightest star in Lyra, which is shaped like a shuttle, the kind used for weaving. Altair is the main star of Aquila, and there are two fainter stars on the left and right sides, representing Two children on a pole."
"What about the other point of the triangle?" Although I have never seen a loom, I probably know something about this shape.
"Tianjin Si is the Tianjin in Tianjin. It is also the brightest star in the constellation Cygnus." After speaking, he pointed to the night sky.
"It doesn't seem to have anything to do with Cowherd and Weaver Girl, does it?"
"It has nothing to do with that story, but because these three stars are highly recognizable, people start from the summer triangle to identify the starry sky in summer nights. And Tianjin 10200 will become the North Star around [-]."
"Brother, how do you know everything?"
Embarrassed by being praised, Yan Che smiled and told the truth: "If you hadn't come with me, how could I have had to hug Buddha's feet temporarily to maintain my great image of knowing astronomy at the top and geography at the bottom?"
Hearing that the other party had done their homework in advance for her own sake, An Rong and her heart burst into a peach blossom fragrance.
Before I had time to thank, I heard Yan Che say again: "But I like to study this since I was a child, but it's impossible to remember everything so clearly."
It turned out that it was not purely for himself, the boy sighed silently in his heart.
"In order to pretend to be aggressive in front of you, I have spent two days filling up relevant information." As soon as he finished speaking, Yan Che blinked his left eye at An Rongyu.
Silently swallowed, why is this person so nice?Such a good person, why can't he still belong to me?
Suppressing his inner thoughts, An Rongyu pretended to be nonchalant and said, "It seems that my mother's tuition fees are not in vain, buy one get one free."
The two continued to chat and laugh about the stars in the night sky, Yan Che really came prepared, he was able to introduce a few of the more eye-catching stars, An Rong and Natural also listened with great pleasure.
Suddenly, like a spring breeze overnight, a burst of urination surged into the boy's heart.He still seems to be afraid of the dreamy encounter with Sister Smelly during the day, and at this moment he is a little afraid to go to the woods for convenience.
Seeing him squirming and hesitating, Yan Che finally couldn't help asking: "Rong Yu, what's the matter with you? Are you uncomfortable?"
Although he doesn't know how to comfort others, his kung fu of observing words and expressions is first-rate.An Rong and Xiao's face was flushed, and finally let go of his guard, and explained his concerns to him.
Yan Che didn't laugh at him, but said that he happened to want to go too, and could help him catch the bugs.
An Rong felt uncomfortable now. In broad daylight, the sky was clear, and she wanted to be with Yan Che in public... Shhhhhhhhhhh.He trembled all over his body, and instantly felt the need to urinate even worse. He couldn't just wet his pants like this. At this moment, he had a sense of righteous determination to die, and followed Yan Che into the grove.
Wait, I and Yan Che walked into...a small forest together on a lonely summer night with no one around?How can this plot make people feel like a fire is on fire, a strong sense of stimulation is coming like a storm, sweeping every cell in his body.
Suddenly, An Rongyu yelled "Damn it" in his heart, looked at Yan Che's back, and without warning...put up a small tent.In desperation, his mind was running fast, and he tried to recall the confusing probability question he wrote a few days ago, and suddenly felt a chill.
It's dangerous, it's dangerous.
Not deep into the jungle, the night sky covered by layers of tree canopies cannot see a ray of light.But at this moment, countless warm yellow dots appeared in front of his eyes.
"Could this be the legendary firefly?" Just as he calmed down, An Rongyu was once again shocked by this spectacular sight.The children in the city today, I am afraid they have never seen fireflies again.
"Yes, its brightness comes from the reaction between luciferin and luciferase in the body. Interestingly, the female has no wings and has a larger body than the male. Although it cannot fly, it is brighter than it."
Never expecting that Yan Che could even name a flower from a firefly, An Rongyu's jaw dropped again in shock.
"It's really interesting. Look at the females of many species in nature that are more majestic and majestic." I don't know what Yan Che thought of before he suddenly added this sentence.
But no matter how beautiful a firefly is, it is still a bug. An Ronghe sincerely hopes that he can keep a distance between himself and this creature that can only be seen from a distance but not played with. water.
Much more comfortable.After Yan Che came back, the two admired the beautiful scenery, and took out their mobile phones to take pictures as a nostalgia.
In the quiet jungle, Yan Che faintly read a poem: "Silver candles and autumn lights are coldly painted on the screen, and small fans are lightly fluttering fireflies. The sky is as cool as water at night, sit and watch Altair Vega."
"Brother, aren't we experiencing the scene described by the great poet hundreds of years ago?" Although he couldn't remember the age and name of the great poet, he still understood the meaning of the poem.
"Almost. Your understanding of ancient poetry has improved a lot now, keep it up."
Yan Che's hand was close at hand, An Rong and Duo wanted to tightly hold that slender, white hand with well-defined joints, and confide to him the deepest feelings buried in his heart under the witness of the stars and fireflies.
【Wishwecouldstayforever,ha|veforevernow】
I don't know how long the two of them stood like that stupidly, and finally got a little tired.After a day of weight-bearing exercise, even professional athletes should be tired.After seeing enough astrology, after deliberation, they decided to sleep for a while.
Because Lancui Mountain is well developed and maintained, there are basically no dangerous wild animals on the route to Range Rover Terrace, and there is no need for someone to keep watch.After setting the alarm clock, the two got into sleeping bags with the skylight on top of the tent.
Originally, he was so sleepy that his eyelids almost fell to the ground. After lying down next to Yan Che, An Ronghe's eyes widened, and his brain began to get excited uncontrollably. It seemed that he would not be able to fall asleep for a while. .
On the other hand, Yan Che's side was calm, without even turning over.The even and subtle sound of breathing tells the tiredness accumulated during the day, the long eyelashes cover the lying silkworm obediently, and the tip of the tall nose reflects a faint light under the flowing starlight.
Looking at the profile of his sweetheart, the young man swallowed, breathing more heavily.Looking further down, Yan Che's lips are moderately sized and thick, and they are the popular smiling lips. The lips are slightly raised, as if they are asking for a kiss, so they are also called "kissing lips".The chin is slightly raised, not to mention earth-shatteringly handsome, but with an indescribable sense of delicacy.Although it can be described as "beautiful", it is indeed a man's face, and it will not make people feel a gender inversion.
An Rongyu looked like he was possessed at this moment, and tentatively called Yan Che a few words. After confirming that the other party had fallen into a deep sleep, he boldly got his upper body out of the sleeping bag, leaned sideways beside Yan Che, and separated him with a punch. Quietly admiring the charming facial features.
After watching without moving for a moment, he closed his eyes, took a deep breath, and said to the sleeping man, "Brother, I like you." He seemed a little choked up.
After a fierce ideological struggle, he slowly moved to the man's chin, carefully leaving a light kiss.
The warm and soft lips left fiery traces on the boy's cold lips. Although the touch was only an instant end, it took the boy several minutes to recover.When the senses gradually recovered, I was shocked to find that there were two lines of clear tears on my face, pouring all over the ground.
He broke free from his sleeping bag and rushed straight into the woods, covering his face and crying bitterly, regardless of bugs or bugs.He didn't care that this was his first kiss, he just hated himself for being shameless, being dazzled by desire and taking advantage of that unconscious person.
After the depression in his chest dissipated, he gently stroked his lips, reminiscing about the superficial water like a brand, as if he was tasting the most delicious food in the whole world.
After tidying up his emotions, An Rongyu returned to the tent, and this time he finally fell asleep without distracting thoughts.
The alarm clock woke people up mercilessly. Fortunately, because of the unevenness of the Range Rover platform, the two did not sleep comfortably and got up without much pain.
The vibe between each other is like none of those things happened last night, and the world goes on as usual.In order to capture the whole process of the sunrise, the alarm clock was set early, and the sky was still dark and dark like night.
After stuffing his stomach indiscriminately, Yan Che set up the camera, and then a series of professional settings. An Rongyu didn't know much about this, so he could only watch the excitement from the sidelines.
After debugging for about half an hour, and expecting the sunrise in half an hour, the two moved up the small bench and sat in front of the tripod to chat.Yan Che patiently explained the phenomena that might appear at sunrise, which made both of them look forward to it even more.
Watching the east, the end of the field of vision is a mountain, the top is not a sharp corner, but a little curved like a bowl.Yan Che calculated that the sun might jump out of the mouth of the bowl after a while, but he was also prepared to adjust the angle at any time.
Unknowingly, the mountains have been filled with thick fog.As the sky began to dim, Yan Che stepped down to look down the cliff, showing a satisfied smile—the thick and churning sea of clouds had completely covered the scenery below the mountain.
An Rongyu also followed silently, he couldn't remember how many times his jaw had dropped since yesterday.
The Range Rover Terrace is the highest peak of the Lancui Mountain Group. At this time, the sea of clouds is almost at the same level as the stone platform, and the mountains and trees are covered by the turbulent waves.Let your eyes go to infinity, adding a sense of vastness and magnificence.
"Good luck. It rained heavily a few days ago. Under the effect of high air pressure, coupled with the abundant water vapor here, due to the uplift of the terrain, the air containing a lot of moisture rose and condensed into clouds." Yan Che said to himself I got up, "Lancui Mountain is 200 meters above sea level, and the morning temperature on the mountain is relatively low. This sea of clouds is stratocumulus clouds in low clouds. But it is midsummer after all, so it probably won't last long."
An Rongyu hurriedly took out his mobile phone and patiently took a few crooked panoramic pictures.Suddenly thought of something, pulled Yan Che over and said, "Brother, let's take a picture!"
Although neither of them had a solid sleep for a few hours, the excitement of their nerves made them look full of energy.A youthful young man with cool and ultra-short hair naturally wraps his arms around the gentle and elegant young man, with his back facing the endless sea of clouds, and freezes the time in the camera.

After a few words, the line of sight suddenly opened up, and the dense forest was drilled out. In front of it was an open platform surrounded by a circle of simple wooden piles. It should be set up by the scenic spot to prevent tourists from accidentally falling off the cliff.
I saw that this spacious platform is about 20 meters square, with potholes and broken stones on the surface.Unlike the green onions behind and in front of the eyes, there is no vegetation growing, not even a thin grass.The two walked to the fence and looked down. There were many pine branches growing on the cliff, full of vitality.

Layers of pollutants filter overshadowed.This time watching the stars with Yan Che at night, he realized that this kind of thing that can be seen from the head can be so interesting.Yan Che's meticulous explanation made this kind of fun a few more levels.
"Summer Triangle. Did you see that very bright star?" Yan Che pointed to the night sky. Among the countless twinkling bright spots, the brightness of that star was definitely one of the best.
An Rongyu nodded, wondering what kind of asterism this big triangle would be.
"That's Vega, which belongs to the constellation Lyra." After glancing at An Rongyu's reaction, it turned out that this star linked to the protagonist in the eternal love story made people feel extremely cordial. "It is the fifth brightest star in the entire sky and was the North Star around 11500 BC and then around 13700 AD."
"There must be Altair in this big triangle, right? I guess the Milky Way is between them!" An Rongyu reacted quickly, and was complacent about his wit at this time.
"Smart. Vega is also the brightest star in Lyra, which is shaped like a shuttle, the kind used for weaving. Altair is the main star of Aquila, and there are two fainter stars on the left and right sides, representing Two children on a pole."
"What about the other point of the triangle?" Although I have never seen a loom, I probably know something about this shape.
"Tianjin Si is the Tianjin in Tianjin. It is also the brightest star in the constellation Cygnus." After speaking, he pointed to the night sky.
"It doesn't seem to have anything to do with Cowherd and Weaver Girl, does it?"
"It has nothing to do with that story, but because these three stars are highly recognizable, people start from the summer triangle to identify the starry sky in summer nights. And Tianjin 10200 will become the North Star around [-]."
"Brother, how do you know everything?"
Embarrassed by being praised, Yan Che smiled and told the truth: "If you hadn't come with me, how could I have had to hug Buddha's feet temporarily to maintain my great image of knowing astronomy at the top and geography at the bottom?"
Hearing that the other party had done their homework in advance for her own sake, An Rong and her heart burst into a peach blossom fragrance.
Before I had time to thank, I heard Yan Che say again: "But I like to study this since I was a child, but it's impossible to remember everything so clearly."
It turned out that it was not purely for himself, the boy sighed silently in his heart.
"In order to pretend to be aggressive in front of you, I have spent two days filling up relevant information." As soon as he finished speaking, Yan Che blinked his left eye at An Rongyu.
Silently swallowed, why is this person so nice?Such a good person, why can't he still belong to me?
Suppressing his inner thoughts, An Rongyu pretended to be nonchalant and said, "It seems that my mother's tuition fees are not in vain, buy one get one free."
The two continued to chat and laugh about the stars in the night sky, Yan Che really came prepared, he was able to introduce a few of the more eye-catching stars, An Rong and Natural also listened with great pleasure.
Suddenly, like a spring breeze overnight, a burst of urination surged into the boy's heart.He still seems to be afraid of the dreamy encounter with Sister Smelly during the day, and at this moment he is a little afraid to go to the woods for convenience.
Seeing him squirming and hesitating, Yan Che finally couldn't help asking: "Rong Yu, what's the matter with you? Are you uncomfortable?"
Although he doesn't know how to comfort others, his kung fu of observing words and expressions is first-rate.An Rong and Xiao's face was flushed, and finally let go of his guard, and explained his concerns to him.
Yan Che didn't laugh at him, but said that he happened to want to go too, and could help him catch the bugs.
An Rong felt uncomfortable now. In broad daylight, the sky was clear, and she wanted to be with Yan Che in public... Shhhhhhhhhhh.He trembled all over his body, and instantly felt the need to urinate even worse. He couldn't just wet his pants like this. At this moment, he had a sense of righteous determination to die, and followed Yan Che into the grove.
Wait, I and Yan Che walked into...a small forest together on a lonely summer night with no one around?How can this plot make people feel like a fire is on fire, a strong sense of stimulation is coming like a storm, sweeping every cell in his body.
Suddenly, An Rongyu yelled "Damn it" in his heart, looked at Yan Che's back, and without warning...put up a small tent.In desperation, his mind was running fast, and he tried to recall the confusing probability question he wrote a few days ago, and suddenly felt a chill.
It's dangerous, it's dangerous.
Not deep into the jungle, the night sky covered by layers of tree canopies cannot see a ray of light.But at this moment, countless warm yellow dots appeared in front of his eyes.
"Could this be the legendary firefly?" Just as he calmed down, An Rongyu was once again shocked by this spectacular sight.The children in the city today, I am afraid they have never seen fireflies again.
"Yes, its brightness comes from the reaction between luciferin and luciferase in the body. Interestingly, the female has no wings and has a larger body than the male. Although it cannot fly, it is brighter than it."
Never expecting that Yan Che could even name a flower from a firefly, An Rongyu's jaw dropped again in shock.
"It's really interesting. Look at the females of many species in nature that are more majestic and majestic." I don't know what Yan Che thought of before he suddenly added this sentence.
But no matter how beautiful a firefly is, it is still a bug. An Ronghe sincerely hopes that he can keep a distance between himself and this creature that can only be seen from a distance but not played with. water.
Much more comfortable.After Yan Che came back, the two admired the beautiful scenery, and took out their mobile phones to take pictures as a nostalgia.
In the quiet jungle, Yan Che faintly read a poem: "Silver candles and autumn lights are coldly painted on the screen, and small fans are lightly fluttering fireflies. The sky is as cool as water at night, sit and watch Altair Vega."
"Brother, aren't we experiencing the scene described by the great poet hundreds of years ago?" Although he couldn't remember the age and name of the great poet, he still understood the meaning of the poem.
"Almost. Your understanding of ancient poetry has improved a lot now, keep it up."
Yan Che's hand was close at hand, An Rong and Duo wanted to tightly hold that slender, white hand with well-defined joints, and confide to him the deepest feelings buried in his heart under the witness of the stars and fireflies.
【Wishwecouldstayforever,ha|veforevernow】
I don't know how long the two of them stood like that stupidly, and finally got a little tired.After a day of weight-bearing exercise, even professional athletes should be tired.After seeing enough astrology, after deliberation, they decided to sleep for a while.
Because Lancui Mountain is well developed and maintained, there are basically no dangerous wild animals on the route to Range Rover Terrace, and there is no need for someone to keep watch.After setting the alarm clock, the two got into sleeping bags with the skylight on top of the tent.
Originally, he was so sleepy that his eyelids almost fell to the ground. After lying down next to Yan Che, An Ronghe's eyes widened, and his brain began to get excited uncontrollably. It seemed that he would not be able to fall asleep for a while. .
On the other hand, Yan Che's side was calm, without even turning over.The even and subtle sound of breathing tells the tiredness accumulated during the day, the long eyelashes cover the lying silkworm obediently, and the tip of the tall nose reflects a faint light under the flowing starlight.
Looking at the profile of his sweetheart, the young man swallowed, breathing more heavily.Looking further down, Yan Che's lips are moderately sized and thick, and they are the popular smiling lips. The lips are slightly raised, as if they are asking for a kiss, so they are also called "kissing lips".The chin is slightly raised, not to mention earth-shatteringly handsome, but with an indescribable sense of delicacy.Although it can be described as "beautiful", it is indeed a man's face, and it will not make people feel a gender inversion.
An Rongyu looked like he was possessed at this moment, and tentatively called Yan Che a few words. After confirming that the other party had fallen into a deep sleep, he boldly got his upper body out of the sleeping bag, leaned sideways beside Yan Che, and separated him with a punch. Quietly admiring the charming facial features.
After watching without moving for a moment, he closed his eyes, took a deep breath, and said to the sleeping man, "Brother, I like you." He seemed a little choked up.
After a fierce ideological struggle, he slowly moved to the man's chin, carefully leaving a light kiss.
The warm and soft lips left fiery traces on the boy's cold lips. Although the touch was only an instant end, it took the boy several minutes to recover.When the senses gradually recovered, I was shocked to find that there were two lines of clear tears on my face, pouring all over the ground.
He broke free from his sleeping bag and rushed straight into the woods, covering his face and crying bitterly, regardless of bugs or bugs.He didn't care that this was his first kiss, he just hated himself for being shameless, being dazzled by desire and taking advantage of that unconscious person.
After the depression in his chest dissipated, he gently stroked his lips, reminiscing about the superficial water like a brand, as if he was tasting the most delicious food in the whole world.
After tidying up his emotions, An Rongyu returned to the tent, and this time he finally fell asleep without distracting thoughts.
The alarm clock woke people up mercilessly. Fortunately, because of the unevenness of the Range Rover platform, the two did not sleep comfortably and got up without much pain.
The vibe between each other is like none of those things happened last night, and the world goes on as usual.In order to capture the whole process of the sunrise, the alarm clock was set early, and the sky was still dark and dark like night.
After stuffing his stomach indiscriminately, Yan Che set up the camera, and then a series of professional settings. An Rongyu didn't know much about this, so he could only watch the excitement from the sidelines.
After debugging for about half an hour, and expecting the sunrise in half an hour, the two moved up the small bench and sat in front of the tripod to chat.Yan Che patiently explained the phenomena that might appear at sunrise, which made both of them look forward to it even more.
Watching the east, the end of the field of vision is a mountain, the top is not a sharp corner, but a little curved like a bowl.Yan Che calculated that the sun might jump out of the mouth of the bowl after a while, but he was also prepared to adjust the angle at any time.
Unknowingly, the mountains have been filled with thick fog.As the sky began to dim, Yan Che stepped down to look down the cliff, showing a satisfied smile—the thick and churning sea of clouds had completely covered the scenery below the mountain.
An Rongyu also followed silently, he couldn't remember how many times his jaw had dropped since yesterday.
The Range Rover Terrace is the highest peak of the Lancui Mountain Group. At this time, the sea of clouds is almost at the same level as the stone platform, and the mountains and trees are covered by the turbulent waves.Let your eyes go to infinity, adding a sense of vastness and magnificence.
"Good luck. It rained heavily a few days ago. Under the effect of high air pressure, coupled with the abundant water vapor here, due to the uplift of the terrain, the air containing a lot of moisture rose and condensed into clouds." Yan Che said to himself I got up, "Lancui Mountain is 200 meters above sea level, and the morning temperature on the mountain is relatively low. This sea of clouds is stratocumulus clouds in low clouds. But it is midsummer after all, so it probably won't last long."
An Rongyu hurriedly took out his mobile phone and patiently took a few crooked panoramic pictures.Suddenly thought of something, pulled Yan Che over and said, "Brother, let's take a picture!"
Although neither of them had a solid sleep for a few hours, the excitement of their nerves made them look full of energy.A youthful young man with cool and ultra-short hair naturally wraps his arms around the gentle and elegant young man, with his back facing the endless sea of clouds, and freezes the time in the camera.
