"Dididi"

Liu Xing opened his eyes and looked out the window, and the genius was bright.

"Kim? Something? Liu Xing asked with a yawn.

"The spacecraft has been built and is ready for test flight."

"Very good, when Zhuge Qiang comes over, I will board the plane for a test flight."

When Liu Xing heard this, he suddenly came to his senses, and softly woke up Shanshan and Hu Die, who were lying beside him.

"Liu Xing, is there anything wrong so early?" Sansa asked, yawning.

The top-secret figure was unobstructed at a glance, shaking Liu Xing only trembling.

"I'm going to take a spaceship test flight today, but let's transport these spirit stones to the big black spaceship first."

Tens of thousands of top-grade spirit stones were placed in this room, and Liu Xing was not at ease.

Wait for the test flight, Jiang Hai will definitely go, and when the time comes, the second elder of Qiankun and the black woman and the white elder will guard here, and the safety factor is too low.

The three of them took out all the storage rings, bracelets, and jade wrenches to be able to put all the spirit stones in place.

Taking advantage of the faint night, all the spirit stones were loaded into the storage room of the big black spaceship, which was the safest place in the spaceship.

The shell of the big black spaceship itself is very hard, and Liu Xing's flying sword can no longer leave any traces on it, and it also has the function of self-repair.

"Xiaojin, has the solar system of the Big Black been set up?"

Liu Xing has always been pained by the consumption of this spaceship, and a hundred top-grade spirit stones can't fly far.

It just fired a few powerful lasers, consuming most of the energy.

"If it is set up, this solar energy system will not have much effect on the earth, if it is in space, the solar energy system can basically meet the daily consumption and flight consumption of the spacecraft."

"That's not bad."

The earth has a thick atmosphere, and a lot of sunlight is consumed, and in space, the temperature on the side of the sun can reach hundreds of degrees Celsius, so solar power generation can increase several times.

"Not only the solar system, but also the thermal difference power generation system, the temperature of the spacecraft facing the light side can be as high as several hundred degrees Celsius, and the backlit side will be more than 100 degrees Celsius, which can use the temperature difference to generate electricity."

"Oh, it's the first time I've heard that the temperature difference can generate electricity." Hu Die wondered.

Although she is a university student, she studied Western medicine.

"I've read in books that when the temperature in a metal is uneven, the kinetic energy of the free electrons at the high temperature is greater than that at the lower temperature."

"Like gases, thermal diffusion occurs when the temperature is uneven, so the free electrons diffuse from the high end of the temperature to the low end of the temperature and accumulate at the low end, creating an electric field in the conductor and a potential difference at the ends of the metal rod. This diffusion of free electrons proceeds until the action of the electric field force on the electrons is balanced with the thermal diffusion of the electrons. ”

Sansa used to be a librarian and had read quite a few books.

"I don't understand it at all!" Liu Xing smiled bitterly.

"I just know some of the principles."

Shanshan stuck out her tongue and said cutely.

"All right, go down, lest the others suspect it."

Liu Xing stepped off the spaceship and personally went to invite Brother Jindan.

Ten minutes later, more than a dozen Jindan monks and dozens of sect leaders came to lead the square.

Liu Xing snapped his fingers.

The large iron door of the factory slowly opened, and a dark black spaceship slowly drove inside.

This spacecraft looks a bit like a manta ray, and it also looks a bit like a B-2 bombardment/plane.

Because it is a transport plane, it is huge. Both the length and width are one hundred and fifty meters long and ten meters high. It can carry four or five hundred tons of cargo.

"Ancestors, masters, please go up and have a visit!"

Liu Xing asked Xiao Jin to open the hatch, and everyone walked into the spaceship with excitement.

The inside of the ship is spacious and the layout is simple. It is divided into two floors, the upper floor can accommodate people, and the lower floor stores goods.

Liu Xing brought them to the wheelhouse, which was the core of the entire spaceship.

"This is the cab, and this robot can help you drive, so you don't have to worry about not having a driver."

Liu Xing pointed to a humanoid robot in the main driver's seat and said.

Everyone looked at the spaceship with a sense of science and technology, and couldn't help but talk about it.

"Alliance leader, I can't imagine that you can make a spaceship so quickly!"

Li Ba of the Kunlun faction has a hot temper, and he has always looked at no one well, but now he is sincerely convinced by Liu Xing.

"Tsk, Jiang Xinyu gave birth to a good son!"

Jiang Hai couldn't help but admire.

"When it comes to slaying demons and eliminating demons, our Shushan Sword Sect should be the first, but the alliance leader's contribution to the human race is the greatest contribution!"

The sword cultivator of the Shushan Sword Sect, who had always been arrogant, also praised again and again.

"Haha, I didn't expect Jiang Xiaobai of the Shushan Sword Sect to praise people! It's rare, it's a rarity! ”

Qing Xuanzi laughed so hard that her fat body trembled, as if she had found the funniest joke, and she laughed so much that she almost burst into tears.

"Bang bang".

A flying sword was pressed against Qing Xuanzi's neck.

"Just kidding, the sword has no eyes, don't hurt the harmony!"

Qing Xuanzi stretched out two chubby hands and carefully removed the sword against his neck.

"Humph!"

Jiang Xiaobai of the Shushan Sword Sect snorted coldly and took back the flying sword.

"Alliance leader, when is the test flight?"

The old poison of the Five Poison Sect asked calmly.

He had seen strong winds and waves, and even when he saw a spaceship, he was not overjoyed.

"Wait, there are a few experts coming!"

Liu Xing looked at the time, it was already eight o'clock, presumably Zhuge Qiang should be almost there.

Say Cao Cao, Cao Cao will arrive.

Zhuge Qiang walked into the cab with three middle-aged men in white.

"Liu Xing, I'm sorry, I'm a little late."

Zhuge Qiang looked at it, dozens of pairs of eyes were staring at him, and these people were all cultivators with high cultivation strength, and the pressure was great.

"It's okay, we've just come up. Sit down, robot, take off! ”

The Devil spewed out a large amount of flames and flew straight above the nine heavens, and in only 57 seconds, it had already flown out of the atmosphere and reached the Earth's escape layer.

"So fast!"

"It's lightning fast!"

"It feels faster than lightning!"

……

When the spacecraft reaches the escape layer, it stops and rotates freely around the Earth.

These Jindan monks can usually fly, but they will never fly very high without anything, at most two or three thousand meters high, no matter how tall they are, they are not comfortable.

And the Earth's atmospheric escape layer is at least 1,000 kilometers, even if it is a Jindan monk, it is beyond the reach of the dust.

According to the physical properties such as temperature, composition, and charge, and taking into account the vertical motion of the atmosphere, the atmosphere can be divided into five layers, including the troposphere, stratosphere, mesosphere, thermosphere, and fugitive layer. The fugitive layer refers to the highest layer of the atmosphere.

The temperature of each layer of the atmosphere is different, when it is relatively close to the ground, the atmospheric temperature is about ten degrees, and then the temperature at the altitude where the plane flies is relatively low, it has reached minus 100 degrees to minus 50 degrees, and finally at the edge of the atmosphere, the temperature rises sharply.

The temperature of the fugitive layer is 2500 degrees Celsius.

Even the Jindan monks will be burned to death.

"What a beautiful earth!"

"It's the first time I've seen the Earth from this perspective, and it's so shocking!"

"Look! The Sahara Desert, as delicate as a watercolor painting! A scientist in a white lab coat said.

"That's Siberia, and the mouth of the river is like a big tree!"

The spacecraft orbits the earth rapidly, and in two hours, you can watch the sunrise and sunset.
