Hum, hum, listen solemnly, but notice the sound of turbulence.

Solemn heart slightly a joy, thought that a helicopter rescue came. However, following the sound, I took a breath of air.

It turned out that the sound was not from the helicopter at all, but from the bottom of airship 1.

With the naked eye, you can see that the air flow is like a vortex, rolling continuously at the bottom of airship 1, just like a jet plane, but the air flow is not as strong as the plane.

"It's really an airship! Is this prison suspended in the air using the principle of airship? This... Is incredible Exclaimed grave surprise.

"It's not only incredible, it's impossible!" Dongping Xinyi was silent for a while and suddenly said.

His words are not aimless, but because the airship really has limited load, it is impossible to hold up a huge building. Even though the building is all made of lightweight composite materials.

The largest airship in the world is the Hindenburg, which was built in Germany in 1936.

Hindenburg was the largest, most advanced and most luxurious airship in the world at that time. It is 248.6 meters long, almost as long as the world's largest passenger liner "Queen Mary" at that time, and the largest diameter is 41.4 meters. In order to build the Hindenburg, 128.8 km long steel wire, 101.43 km long steel bar and more than 5 million rivets were used. Finally, it is wrapped in a huge "cigar" with a huge fiber skin. Such a large airship only weighs 100 tons with fuel and engine, but it can carry 363 tons of passengers and cargo.

Unfortunately, on May 6, 1937, the Hindenburg airship, carrying 97 passengers, flew over the lakeshore naval air terminal in New Jersey to land. Unexpectedly, there were two explosions at the tail of the airship. Then, due to the flammable hydrogen, the whole airship burned and became a huge fireball in the sky. The people present were shocked. The huge airship turned into a fire in a few minutes and fell down slowly. Everyone rushed into the fire to save people. One person gave his life to save people. After everyone's rescue, 61 of 97 people survived, which is a miracle. However, the Hindenburg airship fell and burned into a pile of charred skeletons. The largest and most magnificent airship in the world was destroyed in this way.

Although the Hindenburg can carry hundreds of tons, it is only the weight of a 150 flat building. The construction area of airship No.1 is so large that it is not only the weight of a 150 flat building? Even if it adds up, it will weigh thousands of tons at least.

That's why Dongping Xinyi said that it's impossible. Even though the science is quite advanced, it's very difficult to simply rely on power to support a building floating in the air for a long time.

However, it is not the time to study the suspension principle of No.1 airship, because the biggest problem faced by the solemn four is how to return to the land from the hundreds of meters of air. Otherwise, it's all empty talk, and eventually we have to climb back inside the prison.

"If I really can't think of a way, I'd rather jump straight from here." Dongping Xinyi looked at the undercurrent rolling below and said coldly.

Chen ZhongLuo agreed: "I'm old, and I don't want to go back to suffer any more. Even if you die of chivalrous spirit, you will be able to leave a reputation of dying for freedom. "

It's rare that he still has time to joke.

Donald is afraid to say a word, he may not have the courage to die, but let him climb back, I'm afraid it's impossible.

Only solemn, looking at the sky outside without saying a word, do not know what to think.

In the warden's office.

Finally, a prison officer found that he hadn't received the warden's instructions for a long time and wanted to contact the warden. Then he realized that something was wrong here.

So with the cooperation of these belatedly arrived prison guards, they finally broke the door of the office and woke up Frege.

When freig wakes up, the first thing he does is to push away the guards around him, quickly come to the monitoring platform and open a strange picture. When he fast forward to watch it for nearly ten minutes, a smile appears at the corner of his mouth.

"Ha ha, they think they are smart, but they never think they are still dancing in my palm. You guys, stay here. If they don't show up in that place, they will definitely return from the tunnel. If they dare to come back, I'll let them have a taste of what life is more than death! " There was a crazy light in freig's eyes, he said fiercely.

And this emotional, but affected the injury, let him eat a pain. The injury caused by his solemnity was very strange. Freig felt a dull pain all over his body, as if his bones had been shaken apart. Even if you sit down, you will feel pain because of the stress on your spine.

Although freig is very strange how to have this kind of symptom, he has no time to take care of it at this time. He can only find an injection, inject a painkiller, and then stare at the surveillance screen.

"You say that if the power alone can not support the long-term suspension of airship No.1, what auxiliary means will the architect use to ensure this situation?" The four people in the passage were silent when they spoke solemnly.

What I ask is a silent question.

It's a critical time for his life. He is still asking this kind of question. Does he want to incarnate himself as a scientist?

Dongping Xinyi and Chen ZhongLuo didn't answer, but it was Donald who felt that he couldn't talk about it if he didn't pay attention to it. After all, it was seriousness that brought him out.

He thought for a moment and said, "I think it's possible to build some support around."

"For example?"

"For example, fix the supporting beams on both sides of the canyon, and then build a beam foundation." Donald replied.

"Well, that's about what I thought. In ancient China, there was a famous castle in the air, called Xuankong Temple. It is said that when the Xuankong Temple was built, there were no wooden piles, but when people saw that the Xuankong Temple seemed to have no support, they were afraid that the temple would fall down when they went up. In order to reassure people, some wooden columns were placed under the temple, so some people used "Xuankong Temple, half a day high, three horsetails hanging in the air" to describe the Xuankong Temple. The real center of gravity is supported in the hard rock, and the rock is chiseled into the shape of a right angle trapezoid, and then the flying beam is inserted to make it fully close to the sharp angle of the right angle trapezoid, and the flying beam is semi inserted based on the principle of mechanics. This is the reason why Xuankong Temple can be suspended. I think airship No.1 actually has this kind of application. "

Solemnly, looking out, he said.

"Seriously, do you mean that as long as we can find the flying beams, we can use them to get close to the cliff, and then find a chance to climb up?" Chen ZhongLuo's eyes brightened and asked.

He nodded solemnly and gently.

"If there are flying beams, according to the principle of mechanics, they should be distributed here, here, and these two angles!" Donald quickly drew a figure on the ground, Tao.

Solemnly with the help of the muzzle of the light carefully look, and then frown.

Donald said that the four directions are far away from the vent. Without the help of foreign objects, it's like a fool's dream to move closer to the past.

"See! There it is At this time, Dongping Xinyi suddenly grabbed the wall of the pipe with one hand and half of his body leaned out, waving in the wind and shouting.

His action is extremely dangerous. If he is too bad, he will fall to the bottom.

But seeing his nimble retraction, the man returned to the pipe.

"It's not a flying beam, but it's similar. It's a cable beam. The cable beam nearest to us is seven or eight meters, which is hard to grasp. " Dongping new road.

Seven or eight meters, even on the flat ground is a long distance, not to mention in the valley of the mountain wind. But this gives a serious problem to several people.

"What if we join our clothes together to make a rope and then swing through it with the help of a rope?" Solemn way.

"Theoretically, it can, but the pipeline is smooth. How can we borrow the strength?" Dongping new question.

"I'll stay and send you all over." Solemn calm way.

"What do you do? No, I'll stay! " But Chen ZhongLuo is against it.

"Don't argue with me. I have my own way after seeing you off." Solemnly waved his hand, indicating not to argue on this issue, now time is running out.

Then he takes off his clothes first. The quality of prison clothes is very good. After twisting into a rope, it is absolutely enough to bear the weight of a person.

Dongping Xinyi, without hesitation, took off his clothes and twisted them into a rope to connect them solemnly.

"I owe you my life." Dongping Xinyi looked solemn and said solemnly.

"Two, I'm afraid? You can escape because of me, right Solemn way.

"Before, it was only half a bar, now it is one. I'll remember As soon as dongpingxin finished, he turned around and stopped talking.

Solemnly shaking his head, he took the clothes handed over by Donald and Chen ZhongLuo and tied them together.

Four people's clothes are completely connected, but it's about five meters, although it's still a little short. But both Dongping Xinyi and Chen ZhongLuo have kung fu. With the inertia of throwing up, they can still overcome the gap of two or three meters.

As for Donald, we have to think of another way.

"Come on, who will come first?" Solemnly, although he asked, he looked at Xinyi in Dongping.

Dongping Xinyi is on the outside, but he is the only one.

Dongping Xinyi is not polite. He reaches for one end of his clothes and tries to make it strong. After confirming that there is no problem, he nods to Zhuang: "OK."
