Playing intrigue is worse than engaging in infrastructure

"Your Majesty, will today's incident make the leaders dissatisfied with you?" Wu Qina asked with some concern.

"As long as I don't want to be an obedient and obedient puppet, they will always be dissatisfied." Lian Ti said indifferently.

The struggle between the Mobei Royal Court and various tribes has been like this since the founding of the country. Either the east wind overwhelms the west wind, or the west wind overwhelms the east wind.This is also the situation that every Mobei king must face when he ascends the throne for the first time. Only by completely surrendering all the tribes can he secure the throne.

But if the two parties continue to struggle for power, Mobei will fall into endless wars and internal friction among various tribes.It is precisely because Lian Ti knows this that he has tolerated a lot of tribes in many ways.

Wu Qina also knew it in his heart, but if he was allowed to choose, he would be more willing to stand on the king's side.At least what Wang Shang cares about is the future of Mobei, not beauties with jewels, land, cattle and sheep.

This is a stage that Mobei must go through, either to be truly unified, or to fall apart in the endless struggle, and return to the era of chaos and separatism of the three thousand tribes.

The autumnal equinox is one day away, and Song Qingyuan, who had already prepared, impatiently moved bamboo poles, charcoal pencils and other tools for measuring the sun's altitude angle to the courtyard of the flower hall.

"Jiang Duo, where is True North?" Song Qingyuan, who was squatting on the ground, didn't even raise his head. Hearing the footsteps, he knew that Jiang Duo was coming.

"Eh..." Jiang Duo, who hurried over, looked around and pointed in a direction with some uncertainty, "It should be over there."

"Forget it." Song Qingyuan sighed and stood up the pole.A silk thread tied to a stone hangs down parallel to the pole.

"No problem, it's vertical." He gathered up the rope and put it back in the tool box.

Jiang Duo, who was standing aside, discovered that the small wooden box containing the tools turned out to be a flattened sandalwood shrine!He raised his tone and shouted in shock: "Your Highness, why did you take out the shrine in the study!"

Jiang Duo's voice stammered, he raised his drooping hand, and put it down again helplessly.

"Oh, I'm short of a tool holder. I just saw it fit, so I used it." Song Qingyuan took out a charcoal pencil from the shrine that had been re-employed, and drew a mark in front of the shadow cast by the bamboo pole. Said casually.

"What about the Buddha statue, where did you put it?" Jiang Duo asked fearfully, for fear that Song Qingyuan would give a result he could not accept.

Song Qingyuan fixed the charcoal pencil to the end of the rope, and said casually, "I told Ah Shu to put it away, you can ask him." He waved his hand, motioning for the person standing next to him to come and help.

Jiang Duo pressed the rope on the position where the bamboo pole stood, heaved a sigh of relief, and comforted himself that it was not unacceptable.After all, His Highness didn't throw away the idols on a whim, did he?

Seeing Jiang Duo's reaction was so strong, Song Qingyuan, who was busy drawing circles with a simple self-made compasses, comforted him: "Isn't that statue a gift from Master Nianci? Help you."

Not only was Jiang Duo not comforted at all, but he was even more frustrated because of His Highness's disapproving expression.

"Your Highness, don't be disrespectful to gods and Buddhas." He advised with a worried tone.

"It's okay, the Buddha is merciful, and he won't blame you." Song Qingyuan replied subconsciously.

The circle on the ground was drawn by Song Qingyuan with the position of the bamboo pole as the center and the distance between the shadow and the bamboo pole as the radius.When the apex of the pole shadow falls on the circle again, he can connect the two shadows.

The midpoint of this line and the position of the bamboo pole can determine a straight line.The direction the line points to is true north.

Song Qingyuan still remembered his plan to train Jiang Duo into a scientific and technological talent.After re-erecting the bamboo pole, he stood up, intending to explain to Jiang Duo the principle of distinguishing directions.Turning around, he found that there was no one behind him.

"I guess I'm worried about the Buddha statue." Song Qingyuan sighed in disappointment, and beckoned the servant who wiped the decorations in the flower hall to come over, gave him a charcoal pencil, and told him to stay here until the shadow of the bamboo pole fell on the circle again , trace the shadow with a pen.

The servant who was assigned such a leisurely job rushed down and sent Song Qingyuan away happily.

Just after the time of the second day, Song Qingyuan took Jiang Duo to the flower hall.Yesterday's shadow boy has been drawn, and the line pointing to the true north has also been drawn.Jiang Duo moved a recliner to the side, and he leaned lazily on the back of the chair, waiting for the shadow of the bamboo pole to coincide with the black line pointing to the north.

Today's weather is just right, the sun is warm on the body, and people can't help but want to stretch.There is a passing artificial lake blowing over, bringing a little sweet-scented osmanthus aroma.

Song Qingyuan brushed away the hair that fell in front of his eyes, and narrowed his eyes comfortably.

"Look, Your Highness, the shadow is about to coincide with the line you drew." Jiang Duo gently shook the reclining chair, and Song Qingyuan, who was half asleep and half awake, woke up instantly.

"Let me see." Song Qingyuan stood up from the reclining chair with Jiang Duo's support.Sure enough, a small half of the shadow of the bamboo pole has passed the black line.When the black line reaches the middle of the shadow, it means that it is noon, and the length of the shadow is now the shortest time in a day.

Qingyuan marked the top of the shadow with a horizontal line.He returned to the study with the measured results.

The bamboo pole used by Song Qingyuan for the experiment is 24 inches long, and the length of the shadow is about 16.8 inches.The number obtained by dividing 16.8 by 24 will be the tangent of Beijing's latitude.Not surprisingly, Song Qingyuan really calculated a number that can be extended infinitely.

He slowly wrote down "arctan1.428=" on the paper, took a deep breath, breathed it out again, and began to calculate resignedly.

So Jiang Duo, who came in for Song Luncheon, saw Song Qingyuan frowning, writing many words on the paper that he had never seen before.He picked up a few balls of paper thrown on the ground, and asked with some puzzlement: "Your Highness, what are you writing about?"

Song Qingyuan raised his head, looked at Jiang Duo with raised eyebrows, and asked without answering, "Want to learn?"

Jiang Duo paused for a rare moment, recalling the last time His Highness explained the principles of "drunk oxygen" and "altitude sickness" to him, he shook his head with lingering fear.

"Your Highness, let me go to the kitchen to see if the soup is ready..."

Song Qingyuan picked up the pen with a smile, and wrote down the number 54.99 on the paper.This number is the altitude angle of the sun in Huijing today.

The calculation method of the solar altitude angle is 90° minus the latitude difference between the local area and the position where the sun directly shines.

The sun shines directly on the equator today. According to this formula, the latitude of Huijing can be calculated to be about 35 degrees north latitude.

Song Qingyuan, who finally calculated the latitude of Huijing, let out a long sigh of relief like a wish, got up from the soft couch, and walked to eat contentedly.

"Your Highness."

Song Qingyuan, who had just picked up the chopsticks, saw Jiang Duo running in anxiously. "Didn't you go to see the medicinal meal? Why are you in such a hurry?" He asked with some doubts.

"Mobei sent someone to send a gift, saying that they want to thank His Highness for curing their horse." Jiang Duo explained.

"Then it will be fine if you keep it in the treasury." Song Qingyuan took a mouthful of lettuce and replied casually.

"No, Your Highness." Jiang Duo scratched his head in distress, "It was King Mobei who came in person."

"What?" Song Qingyuan swallowed the green bamboo shoots in his mouth, a rare look of surprise appeared on his face.

"The little one didn't dare to let King Mobei wait at the door for a long time, so he asked someone to invite King Mobei to wait in the main hall first." Jiang Duo replied.

Song Qingyuan nodded slightly, stood up and told Jiang Duo: "You go to serve tea first, and I will go over after changing clothes."

The study and the main hall are connected by a long corridor.As he walked, he thought about Lian Ti's intentions.

But until he entered the main hall, he still couldn't figure it out.Song Qingyuan sighed, gave up empathizing with people with abnormal brain circuits, raised his hand to push aside the curtain, and looked at the person sitting in the main seat.

Lian Ti was wearing a black Japanese uniform today, tied with a girdle that was braided with silk threads and decorated with gold beads. He was bending over at the moment, looking at the pattern on the lacquer plate on the table.

Seeing the person at the door, he straightened his waist, pointed to the lacquer plate on the table and asked, "What is the pattern painted on this plate?"

Song Qingyuan was stunned for a moment, then poked his head over, only to find that the lacquer plate on the table was something he had done when he had nothing to do when he first came to Huijing.The pattern on the plate is a stupid big orange cat, which was taken from a stray cat that he often fed when he was in the company in his previous life.

He couldn't help but miss the big cat that would come to him whenever he saw it, but it seems that there is no such thing as a cat in this era.

Song Qingyuan felt at a loss for words for the first time, and he prevaricated with a guilty conscience: "I don't know, what kind of beast is it?"

"You seem to like this animal very much?" Lianti asked, looking at the lacquer plate.When he looked at the lacquer plate, his eyes would obviously soften, and the corners of his mouth would subconsciously twitch.

Song Qingyuan nodded to express his affirmation, unwilling to continue the deep chat on this matter, sat down at the side, and asked in a flat tone: "Why is King Mobei here?"

"Before I entered the door, the king told your boy, why, you don't know?" Lian Ti smiled a little sternly, and the teacup twirled in his hand.

Song Qingyuan's expression was calm, and his tone did not fluctuate: "It's just a gift, it seems that there is no need to bother a country's monarch to visit in person."

"Haha, I really have other important things to do when I come here." Lian Ti stood up, brushed off the folds of his clothes, with a condescending attitude without a trace of self-confidence, "This king wants to invite His Highness to climb Xiangshan Mountain to enjoy the scenery."

Lanxiang Mountain is not the name of a mountain, but refers to the large area in the eastern suburbs of Huijing City.The environment there is quiet and the scenery is beautiful. Because the mountain can smell different fragrances of flowers all year round, it is named "Lanxiang Mountain".Many Buddhist temples and Taoist temples were built here.The Daxiangguo Temple in the Southern Zhou Dynasty is located on the only way from Tonghua Gate to Lanxiang Mountain. Visitors who come and go will go in and burn incense sticks, worship Buddha and make a wish.

Song Qingyuan looked up at the people in front of him, and asked: "Does the king of Mobei know the rule of the Southern Zhou Dynasty that "protons are not allowed to leave the capital without edict"?" "

"Of course the king knows, but what's the difficulty?" Lian Ti didn't change his face, "If the king wants to take an extra person on the carriage, whoever guards the city will dare to stop the king for inspection."

After a while, Song Qingyuan nodded and accepted his invitation.

"The king will come to visit tomorrow." Lian Ti successfully achieved his goal, took his leave and left.

Song Qingyuan, who brought Lian Ti to the first gate of the palace, thought that his lunch had already cooled down, so he turned and left.

Jiang Duo, who held back all the way, was finally able to speak, "His Royal Highness, is King Mobei really as difficult as you said? How can he be so friendly to His Highness?"

Look, look, Song Qingyuan clicked his tongue. A few days ago at the banquet, he said that he didn't understand etiquette, but today he feels friendly.

Jiang Duo only heard their Highness sneer or snort.

"You look at him as gentle and friendly, but if he is really so harmless, he would have died in the power struggle of several tribes in Mobei, how can he stand here and chat with people?"

Song Qingyuan shook his head. From ancient times to the present, whoever can secure the throne, how can there be one who is pure and harmless?Moreover, the situation in Mobei is much more complicated than that of Nanzhou and Yanyun.

"But... even so, King Mobei doesn't seem to have any malice towards His Highness." Jiang Duo was still a little puzzled.

Song Qingyuan smiled, "How can there be a free lunch in this world? If a person shows kindness to you inexplicably, you have to think about what he wants."

"I understand, little one." Jiang Duo nodded dully, ready to ask someone to remove lunch from the study and ask the kitchen to replace it with new dishes.

"You don't need to redo the kitchen, just heat up the original lunch." Song Qingyuan called Jiang Duo to stop, and ordered, "Go yourself."

"I know." Jiang Duo responded, turned around and ran towards the study.

When the hot food was served again, Song Qingyuan held back Jiang Duo who was about to serve him the dishes, "Do a drug test first."

Jiang Duo froze for a moment when he heard this, "These dishes are all brought to the kitchen to be heated under Xiao Xiao's nose."

"Go for an inspection first." Song Qingyuan didn't explain much, he stayed in the main hall enough time for someone with a heart to sneak into the study and tamper with lunch.

After a while, Jiang Duo came back with a pale complexion, and knelt down with a plop as soon as he entered the door, "It's a small negligence, please punish me, Your Highness."

"I don't blame you." Song Qingyuan nodded unsurprisingly, and helped Jiang Duo who was kneeling on the ground, "Have you found out what the poison is?"

Jiang Duo shook his head with lingering fear, "Not yet, but the government doctor has already been called."

The author says:

Lian mentioned: I came to ask my wife out to play, and my wife agreed, he really has me in his heart!

Song Qingyuan: Tsk, I almost got poisoned.
