Su Ling was very well-behaved, she didn't bother before she knew Chu Lei's purpose, she just watched from the sidelines, feeling that Chu Lei would send a glass of water when he was thirsty, and didn't say anything, just for fear of disrupting Chu Lei's thinking.

After more than half an hour, Su Ling finally saw what Chu Lei was doing, if he guessed correctly, he should be doing a parachute!

Seeing this, Su Ling finally couldn't help it, she thought of a possibility, and opened her mouth to verify: "Brother Chu, are you making a parachute?" Are you ready to leave? ”

Chu Lei didn't have any intention of concealing it, and nodded: "There is not much food left, we have to find a way to get out of here before all it is consumed, I thought about it for a while, it seems that there is only one way to parachute out." ”

"By the way, Su Ling, what do you think, let's talk about it, two people are more reliable than me alone here." Suddenly, Chu Lei thought of Su Ling, eight years of otaku life made him think of solving everything by himself, but he forgot about Su Ling's existence, as the saying goes, three stinkers on top of one Zhuge Liang, maybe Su Ling will have a better idea.

"Okay!" Su Ling smiled and accepted happily.

Subsequently, Chu Lei and Su Ling shared some of their own ideas.

Su Ling listened carefully on the side, she was a top-level figure at school, and it was easy to enter the state, and after thinking for a while, she said her thoughts.

"Brother Chu, I don't think there's any need to think about the problem of weight-bearing, now our body is the best weight-bearing, converted, the garbage bag is actually a natural parachute, if you add the cushion backpack we need to consider in the end, it's actually exactly the same, the main thing is to look at the wind!"

Hearing this, Chu Lei didn't know if what Su Ling said was correct, but he had enough garbage bags, and there were also a lot of other raw materials for making parachutes, which could be confirmed by experiments, no matter how many theories there were, it was not as clear as experiments!

The two hit it off and began to make parachutes, now no more than before the end of the world, these tools now seem to them to be behemoths, it is not easy to assemble them firmly, plus neither of them has experience in this area, so progress is very slow.

It took a whole morning for the two of them to finally make a parachute, which was simple but strong enough, and dragged the parachute to the balcony with a simulated car, and now the floor-to-ceiling windows of the balcony were all shattered, so there was no need to worry about not finding the place to jump.

On the way, Su Ling also saw the abnormality of the simulated car model, and naturally asked questions under curiosity, as for Chu Lei's answer was 'electric', Su Ling was noncommittal to this answer, knowing that Chu Lei was wary of himself, he didn't ask anything more, and became a quiet and obedient baby.

Chu Lei didn't care so much, the spirit line is now his most secret thing, it's better not to let others know, and the explanation is in his hands, he can explain it how he wants, Su Ling loves to guess and let her guess, it doesn't have much impact on Chu Lei, it will only be more jealous of him, why not do it.

Neither of them is a fool, each has its own thoughts, and in this slightly weird atmosphere, the simulated car model came to the balcony position.

The moment she got out of the car, Su Ling hurriedly covered the hem of the paper suit with her hand, and the wind on the balcony was stronger than she imagined!

Chu Lei has already started to work, although the wind on the balcony is strong, but it is not enough to blow people away, but outside the balcony is different, the wind is howling, just listening to it makes people feel palpitations.

In order to avoid accidents, the two still tied a rope around their waists, and fixed the other end to the simulated car model, with the weight of the simulated car model, even if they fell down, they did not have to worry about being blown away by the strong wind outside, and then the two carefully dragged the finished parachute, and put the heavy object down little by little.

Below is the abyss, Chu Lei is standing on the edge of the balcony, it is inevitable that he will be a little nervous in his heart, the weight of these gravel is comparable to his weight plus the designed cushion, the weight is not light, and you have to be careful of accidents, until the parachute is completely lowered It took two people more than twenty minutes.

The thin garbage bag hunted outside the balcony, the two looked at each other, nodded, cut the safety rope at the end of the garbage bag, and in an instant, the garbage bag fell from the twenty-eighth floor!

The two immediately stretched out their heads to observe, the wind was howling in their ears, and nothing else could be heard, and the wind was so strong that it was difficult for the two to open their eyes, but this experiment was related to the lives of both of them, and they both forced themselves to open their eyes, and always maintained a high level of attention!

At first, the landing speed of the garbage bag was a little slower than the two imagined, which was good news, and as it landed about 100 meters, the garbage bag naturally unfolded, and the speed reached a speed acceptable to the two!

However, before the two of them could be happy, the garbage bag in the landing suddenly deviated from the vertical landing route and stuck directly to the outer wall of the building, and then, it can be said to be sticking to the outer wall and sliding down, until the parachute finally turned into a black dot and disappeared from the field of vision of the two!

……

The simulated car model has returned to the living room from the new, there is no wind in the living room, but the two did not untie the rope tied to their waists, the scene just now made the two a little afraid, fortunately, it was just an experiment!

Because by the time the garbage bag disappeared from the field of vision of the two of them, nearly three minutes had passed, and preliminary estimates showed that at least three or four thousand meters had fallen to an altitude.

Chu Lei didn't dare to imagine that he was dragged along the rough wall like that, and it was very likely that he would be blown away by the wind in the middle of the period, and then slammed on the wall fiercely, and when they completely landed on the ground, let alone safe, there might not even be bones left!

"Brother Chu, I think we can learn from those real airborne troops, and then open them after landing to a certain height, so that we don't have to worry about being blown away by the wind during the descent, and it can better ensure that our landing site will not deviate too far, and the ground wind is not as strong as here." Su Ling's face was a little pale, but she had already begun to work hard to find a solution, she wanted to gain Chu Lei's trust, so she could only try to make herself appear more useful.

Chu Lei lowered his head and thought about it, indeed as Su Ling said, he also saw it just now, in the early stage of throwing away the garbage bag, the garbage bag fell vertically before it was unfolded, and it was not until the garbage bag was opened that it was taken astray by the wind.

If you follow Su Ling's method, you can open the parachute when you land hundreds of meters from the ground, this method is also feasible, but neither of them has any experience in skydiving, as long as the parachute is opened too early or too late during the parachute jump, it may cause irreparable and tragic consequences!

The two stopped talking, racking their brains for a better way......

In the end, the two came to the conclusion that they would either land when there was no wind, or deploy their parachutes when they were about to reach the ground, as Su Ling said!

If there is no wind, it is basically impossible, because Xiangrong City is originally a coastal city, and his house is in a high-rise building, whether it is day or night, the wind will not be small, and the only way is Su Ling's suggestion, but there are many problems in this, such as at what height should be expanded, how to ensure that the garbage bag can be safely expanded......

Throughout the day, both of them were thinking and solving problems, and when they had ideas, they would discuss whether they were feasible or not, and keep practicing, and before they knew it, it was already dark.

Although the two of them said today that they did not make anything substantive and rejected most of the proposals, they gained a lot, at least, the possibility of leaving this closed house has become higher and higher.

After dinner, the two rested early after dark, tomorrow, they will start to practice, today's discussion is just a theory, and further experiments are needed to determine whether it is feasible, after all, this is related to the lives of the two, and they can't afford to play!
