Escape the Library

The four of Yue Xingwen jumped out of the helicopter first, and the students in the cabin saw this scene and came to the door one after another.

A girl stretched out her hand and put her long hair on her head: "Come on, jump! It's better than forcibly throwing us in 10 minutes. I don't want to be thrown into the sea to feed the fish!"

She took a deep breath and jumped down, the other three teammates also jumped down one by one.

Soon there were parachutes open on all sides in the air.

In the cabin, Liu Xiaoxiao, who was slightly afraid of heights, turned pale: "Senior brother, we..."

Qin Lang simply said: "Keep up. Pay attention to the height of the parachute. Be sure to open the parachute before 500 meters."

He jumped first, Liu Xiaoxiao grabbed the armrest of the cabin exit with a pale face, next to her, her senior sister patted her shoulder lightly and said, "Don't be afraid, close your eyes and jump down, when you are about to open the height of the umbrella I'll remind you."

Liu Xiaoxiao gritted her teeth, closed her eyes and jumped down, her face was quite heroic as if she "sees death as home".

As one team after another skydive, others came to the cabin door.

Except for those with severe fear of heights, who had weak legs and refused to let go of the guardrail, most of the classmates dared to jump down. For a time, open parachutes were everywhere in the air, like clusters of petals floating around.

Many people can't control the direction, plus the sense of fear caused by weightlessness and rapid falling, there are bursts of "Aah" screams around, mixed with the whistling wind, which reaches their ears.

Jiang Pingce couldn't care about others, he only stared at the three teammates below.

At this time, the first skydiving Yue Xingwen was less than 500 meters away from the ground, and the scene of the deserted island came into view. Jiang Pingce found that the four of them skydived were very close to a mountain. Seeing that Yue Xingwen was about to hit a cliff within a few dozen meters, Jiang Pingce immediately stretched out his right hand.

Right hand rule, Cartesian coordinate system.

Three coordinate axes appeared in front of him. The three teammates were like blue dots, falling continuously in the coordinate system. Jiang Pingce estimated the coordinate position of Yuexingwen and wrote a parabolic formula at a very fast speed. .

Yue Xingwen is trying hard to reverse the direction of the parachute.

The wind is too strong, and the wind will continue to float forward, and it will definitely hit the cliff!

Just at the moment when he was extremely anxious, suddenly there was a magical power that seemed to wrap his whole body, and his body began to fly diagonally upwards involuntarily——

By the time Yue Xingwen recovered, he had landed on the top of the mountain steadily.

It was impossible for the parachute to fly up inexplicably while the parachute was falling. Yue Xingwen stood on the top of the mountain for two seconds, and quickly realized that Jiang Pingce saw that he almost hit the mountain, so he changed his trajectory.

After experiencing it once, Yue Xingwen discovered the power of the mathematical coordinate system control field.

The movement trajectory calculated by the mathematical formula will not be affected by external factors such as wind direction and gravity. Whichever point Jiang Pingce has calculated accurately, the target controlled by him will fall exactly on that coordinate point.

Yue Xingwen looked up, Liu Zhaoqing and Ke Shaobin also fell next to him one after another, Jiang Pingce was the last one to fall, and the four fell less than two meters apart.

If it wasn't for Jiang Pingce's formula control, they would definitely not be so neat and tidy with the wind.

Yue Xingwen stepped forward, patted Jiang Pingce on the shoulder, and said, "Amazing! You wrote four formulas in the blink of an eye, and you have calculated our placement."

His hair was ruffled by the wind, but his smile was bright.

The corners of Jiang Pingce's lips raised slightly, and he said with concern, "Didn't you bump into it?"

Yue Xingwen waved his hand: "It's alright, with you in control of the movement route, I landed very steadily just now!"

Liu Zhaoqing and Ke Shaobin also walked towards this side.

Ke Shaobin was in shock, his glasses almost fell off. He quickly put them on, looked at Jiang Pingce and said, "It turns out that Pingce is in control, no wonder I was able to land on the top of the mountain. I was thinking just now, will it fall if I fall? A dog eats shit."

Liu Zhaoqing joked: "It's not bad to throw a dog and eat shit, but I'm afraid we will fall into a box."

Finding that no one was injured, Yue Xingwen breathed a sigh of relief and said, "It's better to fall on the top of the mountain, we stand on a high place, we can look at the surrounding environment and discuss how to go."

Jiang Pingce asked, "Where's the map?"

Yue Xingwen put away his parachute and turned over his backpack to find it - the tools in the bag included a map, a compass, an ancient pocket watch, and a lighter.

Simple, just these four.

Liu Zhaoqing couldn't help but complain: "Don't give me a bottle of water, let's stay for three days and drink the northwest wind?"

Ke Shaobin looked around and said in a low voice, "Probably let us source materials from the local area? There should be wild fruits and vegetables on this deserted island. Maybe they can also roast pheasant and hare to eat? The lighter is for us to make a fire. of."

Jiang Pingce asked calmly, "Who among you can tell whether the wild fruit is poisonous or not?"

The three fell silent at the same time.

They are just ordinary college students. Who has the experience of survival in the wild?

Yue Xingwen said with a wry smile, "Don't eat wild fruits, mushrooms, etc., it's easy to be poisoned. As for the pheasant and hares mentioned by Ke Shao... I don't think this desert island looks like such a small animal, Haili said. There may be fish."

Liu Zhaoqing said: "If you don't eat for three days, you won't starve to death. Don't worry about that. Let's see what's going on with the map. This mode is very similar to a real person eating chicken. Do we need to go to the safety zone?"

Yue Xingwen found a rock, spread the map on the big rock, and analyzed it with everyone.

This map is much larger than he imagined. The map has directions and distance conversion labels, and a red flag is marked in the center with the words "end point" written.

Yue Xingwen pointed to a place similar to a mountain on the map, looked at Jiang Pingce and said, "Our location should be this mountain top. The map scale is 1:500 meters, can you calculate the distance between us and the end point? "

Jiang Pingce narrowed his eyes slightly and made quick calculations in his mind.

Soon, he came to the result: "The distance in a straight line is 20 kilometers, but due to obstacles such as swamps and jungles along the way, we want to reach the end point in 3 days, and we can't walk in a straight line. If we take a detour..." He pointed with his finger He quickly drew a tortuous path on the map and said, "About 45 kilometers."

Liu Zhaoqing scolded in a low voice, "Fuck, 45 kilometers on foot! We never traveled this far in military training!"

Ke Shaobin adjusted his glasses and asked earnestly, "Can you write a parabola formula and throw us directly over it?"

Jiang Pingce: "..." He was a little speechless about Ke Shaobin's question.

Seeing his serious face, Yue Xingwen took the initiative to explain: "Definitely not, Pingce's coordinate system can control the coordinates and paths within his field of vision, and he can't see it at all 45 kilometers away. Second, the coordinate system is this The cooldown time of this kind of big move should be long, and it is impossible for people to use it indefinitely, right?"

Jiang Pingce nodded: "Yes."

Ke Shaobin blushed slightly: "Cough, I just said it casually."

Liu Zhaoqing said, "Junior Brother Jiang, do the math, if we start walking from now on, how long will it take to get to the end?"

Jiang Pingce frowned and said: "The normal walking speed of an adult is 12 minutes for 1 km, and 10 km takes 2 hours. In addition to physical exertion, in theory, it takes more than 10 hours to walk 45 km."

He pointed to the two coordinate points on the map and said, "The exam time is 3 days, and we can move forward 15 kilometers every day. Using this and here as a transfer station for two breaks can ensure sufficient physical strength to deal with all kinds of problems. Unexpectedly, I was able to reach the finish line on time before the end of the test on the third day and collect enough scorecards."

Yue Xingwen looked down at the path he drew on the map, and said in agreement: "The moving route covers the left and right sides of this area, we can spend more time scouting the surroundings and put all the score cards in this area. Get it."

Liu Zhaoqing took a closer look at the map and felt that it was quite the same.

The path planned by the top student in the mathematics department is definitely the best path that is both efficient and fast. Even a medical student's map can be understood but not understood, so give up thinking and just follow.

Ke Shaobin simply took out his laptop and said, "In order to avoid losing the map, I'll make a backup copy on the computer and model the route of Pingce, so that Xiaotu can investigate the surrounding environment."

Jiang Pingce said, "Well, I'll help you."

The two science students started modeling on their laptops on the spot.

This kind of map modeling is not difficult. With Jiang Pingce helping to organize the data, Ke Shaobin quickly made a 3D version of the map with his fingers on the keyboard.

They were given a floor plan for the exam. Ke Shaobin made a three-dimensional one. The heights of the peaks were also marked, and the radiation range around the best path was also circled with blue lines, as if to say: "This site is ours. ."

Liu Zhaoqing watched and praised: "With the two of you here, will you be able to come up with a simulated map every time you go to an unfamiliar environment? Are all science students so hard-core?"

Yue Xingwen smiled and said, "Not all science students are so hard-core, it's because Ke Shao and Ping Ping are too strong."

On-site modeling is really a piece of cake for Ke Shaobin and Jiang Pingce. They can use the skills provided by the library to the extreme. If you are a scumbag, you can't calculate the formula for a long time if you get the skill of the coordinate system, and your teammates have fallen to death...

Just thinking of this, a prompt popped up in the floating box in the upper right corner—

【The exam officially begins】

[Number of candidates on desert island: 88]

Everyone saw this prompt.

Ke Shaobin was stunned: "Is there only 88 people on the island?"

Yue Xing Wen said: "It seems that 12 candidates fell to their death, or landed at sea and drowned, and were eliminated directly."

The four of them looked at each other, remembering the scene of jumping from the sky just now, and they couldn't help but feel terrified. It is the first time for everyone to experience skydiving, and it is a blessing to be able to land smoothly.

Those 12 unlucky candidates really responded to Brother Liu's words: It's really miserable to fall into a box.

Immediately following, the transparent floating box in the upper right corner lists a row of information——

【Points Card Ranking】

【A-76 group 20 points】

【B-16 group 15 points】

[10 points for c-11 research group]

【A-53 subject group 5 points】

At present, there are only four subject groups on the list. As soon as the exam started, they collected point cards. Obviously, there were cards near where they landed, and their luck was overwhelming.

Seeing this row of information, Liu Zhaoqing couldn't help complaining: "It tastes like chicken, and the rankings are updated in real time!" He paused and asked worriedly: "In the later stage, will the students compete for the score card? Infighting?"

Yue Xingwen thought for a while, then shook his head and said: "This is quite different from eating chicken. The winner of eating chicken must kill all other teams and survive to the end to win. This time we orienteeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee Contradictions, as long as you get 60 points, you will pass the test. Moreover, everyone is not very clear about the abilities of other majors, and if you rashly do it, you may be killed."

Liu Zhaoqing agreed: "That's right. A weak girl like Liu Xiaoxiao can give a lecture to the monkey and make the monkey stand for 15 seconds. Who knows what strange abilities other majors have. Our class should be all matched. The research group, the group and the group k, rashly do it, it is not necessarily a bargain."

Ke Shaobin said: "Yeah, if we encounter the direct throwing sulfuric acid from the Department of Chemistry, even if we win, we will be disfigured."

Yue Xingwen said: "We don't provoke other teams. The area planned by Ping is big enough, and it should be able to collect a lot of score cards."

The map model on Ke Shaobin's side has been completed.

Jiang Pingce straightened up and said, "Let's go, before it gets dark, search the scorecards on the mountain."

The boy with a height of 189 wears a military green camouflage uniform. When he walks with his long legs, his movements are neat and neat. This outfit makes him look very handsome. The originally tough facial features are even more heroic under the background of the military uniform.

Yue Xingwen quickly followed him, walked side by side with him, and asked in a low voice, "It's two o'clock in the afternoon now. Shall we spend the night at the top of the mountain tonight, or go down?"

Jiang Pingce said, "Let's go down the mountain. Only our team should have landed on the top of the mountain. The other teams are all at the bottom of the mountain. If we go down the mountain too late, the scorecards near the bottom of the mountain will be collected."

Yue Xingwen also thought so: "Well, let's hurry up and scan the top of the mountain first."

The two stared left and right in tacit understanding, and after walking about ten meters, Jiang Pingce suddenly narrowed his eyes and pointed to a tree ahead: "There is light on it, I don't know if it is a score card."

The trunk of this tree is as thick as the arms of an adult, and the canopy is dense with foliage, forming a large natural shade. Yue Xingwen followed Jiang Pingce's gaze, and as expected, there seemed to be something flickering in the middle of the leaves. The light was very soft, just like the corresponding items would glow when encountering a collection task in the game.

It's just that this tree is too tall, isn't it? And the trunk is very smooth, there is no borrowing point.

Yue Xingwen thought thoughtfully: "How to climb up?"

The four stood under the tree and looked at each other. Does this orienteering also test the students' ability to climb trees?

Ke Shaobin whispered, "Can Pingce's coordinate system be sent up?"

Jiang Pingce said blankly, "It's cooled down."

"Oh." Ke Shaobin scratched his head: "My robot can't climb trees either."

Liu Zhaoqing said, "The card is in the middle of the leaves, and my scalpel can't be aimed."

"Look at me." Yue Xingwen suddenly took out the dictionary and said with a smile, "Stand away, don't hit you."

The three looked at each other and took a quick step back.

Yue Xingwen closed one eye and aimed at the light on the tree with his right eye. He raised his head and threw the dictionary towards that position violently - only to hear a loud "bang", and the branches were smashed. It shook for a while, and then snapped with a snap!

As the branches fell, a green card floated down gently.

Yue Xingwen looked overjoyed, and reached out to take the card, only to see the word "5" written on the back of the green card, followed by a system prompt in everyone's ears: "The c-183 research group has obtained a green card, adding 5 points. ."

Yue Xingwen stuffed the card into his pocket, smiled and looked at his teammates: "It's done!"

Three people: "..."

At the critical moment, the dictionary of Xingwen is easy to use. His dictionary is like a brick, where it needs to be moved.
