'Buzz'

Between the blue sky and white clouds, the beautiful Dapeng bird shuttles between the clouds and mist, soaring into the sky.

The people below watched and talked and applauded.

On the plane, the pilot looked at the speedometer and was also very excited, pulling more than two tons of weight. At this time, the speed of the flight had already exceeded 180 kilometers. If you can maintain this speed all the time and be able to fly stably for a long time. Pengshi succeeded.

He stopped at an altitude of three thousand meters. Nor did he go to any higher places.

Three thousand meters is within the safe zone, no one has been there above three kilometers, it is an unknown territory. Everyone was curious, eager to try, and at the same time full of fear.

Perhaps this heaven and earth is a cage that imprisons all living beings in this world. Stratosphere, an absolute no-go zone.

Is it an absolute no-go zone?

No.

'Aung Aung Aung'

The plane descended, and the airport erupted in strong applause, which lasted for a long time.

Li Zhen looked at Peng Shi, who was surrounded by everyone, with a smile, and then walked into the pergola, looked at Gao Zhihang and said, "Do you think the stratosphere is a forbidden area?" ”

Gao Zhihang nodded solemnly: "That's an absolute forbidden area." Li Shi stated in the book that the stratosphere is a stable, but unbearable place. There will be atmospheric pressure, there will be anaerobic, and it will be extremely cold. An absolute no-go zone for living beings. ”

Li Zhen shook his head: "It is not absolute to say that it is a forbidden area. It's just a relative no-go zone, but it's not that hard to get to. ”

"Isn't it difficult?"

"Hot air balloons can go to the stratosphere."

"Huh?"

"There is a bird and beast called the alpine vulture, and the highest flight altitude can reach 10,000 meters."

"Huh?"

"The ideal flight area for an aircraft is in the stratosphere, which is far safer and more reliable than flying in the troposphere."

"Huh?"

"Airplanes fly in the stratosphere and don't encounter bird strikes. The speed will be faster and the field of vision will be better. At the same time, fuel consumption is lower. ”

"Huh?"

Gao Zhihang was pleasantly surprised: "Didn't Master Li say in the book that the stratosphere is a forbidden area?" In that case, the plane should be flying in the stratosphere. ”

Li Zhen shook his head: "It's said it's a forbidden area, but it's not a forbidden area." It's not a no-go zone, it's a no-go zone. ”

"This reconciliation again?"

"After breaking through the clouds and rain in the troposphere, your field of vision will be wider. But the terrain below will also become blurry, and all you can see is white clouds, and you can't see anything below. That place was so high that even the pilots with the best eyesight could not see through the space of ten kilometers and penetrate a kilometer of clouds. Stratosphere, above the white clouds. ”

Gao Zhihang's face was fascinated, and his heart was full of doubts, how did Master Li know the beauty of the stratosphere? He described it as if he had seen it with his own eyes, but how did he know it?

"Then Master Li, how can I enter the stratosphere?"

"You can enter the stratosphere at any time, but the requirements for the aircraft are extremely high. I think Peng style is competent. I had people send you a telegram and tell you not to go up again because you were crazy. The success of Pengshi is very important, and everything is stable in the test flight. We can't do anything that is excessive, we just want to be stable. Can't get sideways, so let you down. ”

"Ah......h

Gao Zhihang's face was a little red, he knew why he had changed pilots.

Li Zhen said again: "But Peng Shi has the strength to enter the stratosphere, it is stable enough, strong enough. If the cabin is sealed with rubber and the pilot carries oxygen equipment. The Peng is fully capable of flying in the stratosphere. Peng Shi does not need to face atmospheric pressure, because he only needs to fly at an altitude of ten kilometers, and the atmospheric pressure in that place is not to be feared. ”

"Then Master Li, let's hurry up and seal it. I think the sky is in the stratosphere. ”

"No, there's one thing that doesn't show up."

"What's that?"

Li Zhen's eyes were a little ethereal, and he muttered: "The latitude and longitude of this world have not been determined. Without latitude and longitude, we can only rely on the naked eye to discern the direction. ”

"Latitude and longitude?"

Gao Zhihang frowned. He hadn't heard of the concept.

Li Zhen ignored this stubble and said with a smile: "These things take time. But if you want to try 100,000 meters at a time, I'll allow you to do an experiment right now. ”

"Really?"

"Yes, but you need to complete a mission."

"What task?"

"Bring a photograph and take a picture at an altitude of 10,000 meters."

Gao Zhihang's eyes lit up: "No problem." Guaranteed completion of the task. ”

Li Zhen nodded with a smile, and immediately ordered someone to come: "Peng-style extinguish the fire and use rubber to strengthen the sealing conditions in the cabin." Get the oxygen cylinder. ”

"Master Li, what do you want to do?"

"Captain Gao wants to use the Peng style to challenge the altitude of ten kilometers."

"Huh?"

“……”

Everyone was shocked, and after hearing the news, they walked into the pergola together, with a look on their faces that was novel, expectant, and nervous.

Many people have read the books compiled by Li Zhen, and they are afraid of the stratosphere.

And today, is it to break through the shackles of the sky and jump out of the cage to look down on the world?

When everyone walked into the pergola, there were thousands of words that they wanted to ask, but after seeing Li Zhen, no one said anything more.

At this time, Li Zhen's face was full of excitement, he was not as calm as in front of Gao Zhihang.

Compared with Gao Zhihang, Li Zhen also fantasizes about the forbidden area of the stratosphere, and he even wants to know what the stratosphere looks like above Gao Zhihang. Due to various reasons and conditions, Shinkyushu has not had the strength to enter the stratosphere before.

And Zhang Zhi's description of the stratosphere made Li Zhen have a lot of fantasies.

Zeng Zhang Zhi told Li Zhen: "Our world plane is a means of transportation, and after you get on the plane, you will go to the sky with a swish." In the blink of an eye, he was already 10,000 meters in the air. At this point, you break through the troposphere, which is the layer of clouds and rain. At this time, the clouds are under your feet, they are like cotton candy, giving you the illusion that it seems to be a continent, it is a heavenly palace, as if you can jump off the plane and step on those clouds. Because those clouds are solid.

When you enter the stratosphere, the sky is clear. It doesn't matter if your city has thunderstorms or not, but once you enter the stratosphere, there are no more meteorological conditions. You see the golden sun shining all over the sky. Your friends will be waving to you on the ground, but of course you can't see it.

At this time, what you can see is the magnificence and mountains and rivers of the motherland. Truly magnificent. ”

A few years ago, Zhang Zhi told Li Zhen a lot about their world.

The stratosphere left a very strong mark on Li Zhen's heart. He once secretly fantasized that if one day, he must be able to create a flying machine that enters the stratosphere, and also take a look at the magnificence and splendor of the motherland.

He is looking forward to it even more than Gao Zhihang!
