Escape From the Library

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

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

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

Soon there were more parachutes in the air.

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

Qin Lang said bluntly: "Come on. Pay attention to the height prompt of the parachute. You must open the parachute before 500 meters."

He jumped down first, and Liu Xiaoxiao grasped the handrail of the cabin exit with a pale face. Next to her, her senior sister patted her on the shoulder lightly and said, "Don't be afraid, just close your eyes and jump down. It's almost time to open the parachute." I'll remind you."

Liu Xiaoxiao clenched her teeth, closed her eyes and jumped down, her face was quite heroic "seeing death as home".

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

Except for those with severe fear of heights who had weak legs and hugged the guardrail and refused to let go, most of the students bit the bullet and jumped down.For a moment, the entire sky was filled with open parachutes, floating around like clusters of flower petals.

Many people don't know how to control the direction, and coupled with the fear of weightlessness and rapid falling, there are bursts of screams of "ahah" around, mixed with the whistling wind to the ears.

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

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

Right hand rule, Cartesian coordinate system.

Three coordinate axes appeared in front of his eyes, and the three teammates were like blue points, falling continuously in the coordinate system. Jiang Pingce estimated the coordinate position of Yue Xingwen, and wrote a parabolic formula at a very fast speed .

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

The wind is too strong, if you continue to float forward if you are blown by the wind, you will definitely hit the cliff!

At the moment when he was extremely anxious, suddenly there was a magical force that seemed to envelop his whole body, and his body began to fly obliquely upwards involuntarily——

By the time Yue Xingwen came back to his senses, he had landed steadily on the top of the mountain.

It is impossible for the parachute to fly up inexplicably during the fall of the parachute. Yue Xingwen stood on the top of the mountain in a daze for two seconds, and quickly realized that Jiang Pingce must have seen him almost hit the mountain, so he changed his trajectory.

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

The trajectory calculated by the mathematical formula will not be affected by external factors such as wind direction and gravity. When Jiang Pingce calculates the exact landing point, the target under his control will land on that coordinate point exactly.

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

If Jiang Pingce hadn't used a formula to control them, they would definitely not be so neatly drifting 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 accurately calculated our landing points."

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

The corners of Jiang Pingce's lips raised slightly, and he asked in concern, "Did you hit him?"

Yue Xingwen waved his hand: "It's okay, with you controlling the movement route, I landed very steadily just now!"

Liu Zhaoqing and Ke Shaobin also walked over here.

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

Liu Zhaoqing joked: "It's not bad to drop 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 fine if we land on the top of the mountain. We stand on a high place, so 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, turned over his backpack and looked for it—the tools in the bag included a map, a compass, a very old pocket watch, and a lighter.

Simple, just these four pieces.

Liu Zhaoqing couldn't help complaining: "We don't even give you a bottle of water, let us stay for three days and drink the northwest wind?"

Ke Shaobin looked around and said in a low voice: "Probably let us get local materials? There should be wild fruits and wild vegetables on this deserted island, maybe you can get some pheasant and hare roast to eat? The lighter is for us to light the fire." of."

Jiang Pingce asked calmly: "Who among you can tell whether wild fruits are poisonous?"

The three fell silent at the same time.

They are just ordinary college students, who has the experience of living in the wild?

Yue Xingwen smiled bitterly and said: "Wild fruits, mushrooms, etc., don't eat them indiscriminately, they are easy to be poisoned. As for the pheasant and hare Ke Shao mentioned... I don't think there are such small animals on this deserted island, Haili said There may not be fish."

Liu Zhaoqing said: "You can't die without eating for three days. Don't worry about it. Let's see what's going on on the map. This mode is very similar to real people eating chicken. Do we need to go to the safety zone?"

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

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

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

Jiang Pingce narrowed his eyes slightly, and quickly calculated in his brain.

Soon, he came up with the result: "The straight-line distance is 20 kilometers, but because there are swamps, jungles and other obstacles along the way, we want to reach the finish line within 3 days, so we can't take a straight line. If there is a detour..." He pointed Quickly drew a tortuous path on the map and said, "About 45 kilometers."

Liu Zhaoqing cursed in a low voice: "Fuck, walk 45 kilometers! We never walked so far in military training!"

Ke Shaobin adjusted his glasses, and asked seriously: "Can you write a parabolic formula and throw us directly?"

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

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

Jiang Pingce nodded: "Yes."

Ke Shaobin blushed slightly: "Well, 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 reach the finish line?"

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

Pointing to two coordinate points on the map, he said: "The exam time is 3 days, and we can advance 15 kilometers a day. Using this and this place as a transfer point for two rests can ensure sufficient physical strength to cope with various challenges. Unexpectedly, I was able to reach the finish line on time before the end of the exam on the third day and collected enough point cards.”

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

Liu Zhaoqing looked at the map carefully, and felt that it was quite similar.

The path planned by the top student in the Department of Mathematics is definitely the best path that is both efficient and fast. Even a medical student like him can half-understand the map, so give up thinking and just follow along.

Ke Shaobin simply took out his laptop and said, "In order not to lose the map, I'll make a backup copy on the computer and model the route of Ping Ce so that Xiaotu can scout the surrounding environment."

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

Two science students started modeling on the laptop on the spot.

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

The exam sent them a floor plan. Ke Shaobin made it three-dimensional, and the height of the mountain was 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 looked at it from the side and praised: "With the two of you here, will you be able to create a simulated map every time you go to a strange environment? Are all science students so hardcore?"

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

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

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

【The exam officially begins】

[Number of Candidates on Deserted Island: 88]

Everyone saw this reminder.

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

Yue Xingwen said: "It seems that 12 candidates fell to their deaths, or fell to the sea and drowned, and were directly eliminated."

The four of them looked at each other, recalling the scene of jumping from a high altitude just now, they couldn't help but feel lingering fear.It was the first time for everyone to experience high-altitude skydiving, and it was a blessing to be able to land smoothly.

Those 12 unlucky examinees really answered Senior Brother Liu's words: "It's too miserable to fall into a box."

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

【Scorecard Ranking】

[a-76 subject group 20 points]

【b-16 subject group 15 points】

[c-11 subject group 10 points]

[a-53 subject group 5 points]

At present, there are only four research groups on the list. They collected score cards just after the exam started. Obviously, there happened to be cards near the landing place, and they were lucky.

Seeing this row of information, Liu Zhaoqing couldn't help complaining: "It tastes like eating 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. In our orienteering, there is no difference between the teams. Contradictory, as long as you get 60 points, you will pass the test. Moreover, at present, everyone is not very clear about the abilities of other professions, so if you do it rashly, you may be counter-killed."

Liu Zhaoqing agreed: "That's right. A weak girl like Liu Xiaoxiao can give lectures to monkeys and make them stand for 15 seconds. Who knows what strange abilities other majors have. In our class, we should all be matched with The research group, group and group K, if they act rashly, they may not necessarily get a bargain."

Ke Shaobin said: "That's right, if we encounter someone from the chemistry department who directly throws sulfuric acid, even if we win the fight, we will still be disfigured."

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

Ke Shaobin's map model has been prepared.

Jiang Pingce stood up straight and said, "Let's go, before it's dark, search for the points card on the mountain."

The boy with a height of 189 was wearing an army green camouflage uniform. When he walked with long legs, his movements were crisp and neat. This attire made him look very handsome.The originally tough facial features are even more heroic against the background of the military uniform.

Yue Xingwen quickly followed him, walked side by side with him, and asked in a low voice: "The time is now two o'clock in the afternoon, shall we spend the night on the top of the mountain tonight, or go down the mountain?"

Jiang Pingce said: "Let's go down the mountain. Only our team has landed on the top of the mountain, and the other teams are all down the mountain. If we go down the mountain too late, the score cards near the foot of the mountain will be collected."

Yue Xingwen thought the same way: "Well, let's hurry up and sweep the top of the mountain first."

The two stared at the surroundings from left to right in tacit understanding. After walking about ten meters, Jiang Pingce suddenly narrowed his eyes and pointed to a tree in front of him: "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 crown of the tree is dense with branches and leaves, forming a large natural shade.Yue Xingwen followed Jiang Pingce's gaze, and found that there seemed to be something flickering in the middle of the leaves. The light was very soft, just like when encountering collection tasks in the game, the corresponding items would glow.

But, isn't this tree too tall?And the trunk is very smooth, there is no leverage point.

Yue Xingwen was thoughtful: "How to climb up?"

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

Ke Shaobin whispered: "Ping Ce's coordinate system, can you send people up?"

Jiang Pingce said blankly, "It's cooling 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, I can't aim the scalpel."

"Look at mine." Yue Xingwen suddenly took out the dictionary, and said with a smile, "Stay far away, so as not to hit you."

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

Yue Xingwen closed one eye, aimed at the light on the tree with his right eye, raised his head, and threw the dictionary towards that position—only heard a loud "bang", and the branch was smashed to pieces. It shook for a while, and then snapped off with a snap!

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

Yue Xingwen was overjoyed, and reached out to take the card, only to see the word "5" written on the back of the green card. Immediately afterwards, a system prompt sounded 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, Xingwen's dictionary is still easy to use.His dictionary is like a brick, which can be moved wherever it is needed.
