"How to change the composition of the atmosphere?" Ye Chen asked in confusion, this question is probably not much simpler than changing the surface of the planet, all kinds of gases in the atmosphere are mixed together, it is difficult to separate them, Ye Chen doesn't know, Zode and they have any way to separate these evenly mixed gases.

Zode said: "Under normal circumstances, the planetary colonies we are looking for contain a lot of water, so that a large amount of oxygen and hydrogen can be obtained by electrolyzing these waters, and after the hydrogen is stripped away, oxygen enters the atmosphere, and many toxic gases in the atmosphere can be burned, and these toxic gases react with oxygen to convert toxic gases into non-toxic gases, so that the atmospheric composition of the entire planet will change." ”

Ye Chen nodded and said, "This can indeed be regarded as a method, but I think that the energy you need to consume in this method is probably not small, if you want to ionize oxygen that can change the composition of a planet's atmosphere, that huge amount of energy will probably reach an astronomical amount." ”

Ye Chen roughly estimated that in order to obtain the oxygen content that meets the requirements, the energy required to be consumed is enough to be higher than the energy consumed by all human beings on the earth for a thousand years, which is definitely an extremely huge project.

"That's right, it takes a lot of energy, but we Kryptonians are never short of energy, and the energy facilities we use are somewhat similar to the nuclear fusion reactions on your earth, which convert the mass of matter into energy, but our mass and energy conversion efficiency is much higher than yours, and the restriction of raw materials is smaller than yours, so you don't have to worry about energy, what we need is sufficient water."

Zod looked up at the Earth, which was so small in the distant sky that it was almost indistinguishable from the other stars, and smiled disdainfully, as if to laugh at the backwardness of technology on Earth.

"The water source is easy to handle, just leave this to me, Europa I left behind. It's a planet covered in ice and snow, and if I move it over, won't the problem of water be solved? ”

Zod was stunned for a moment and said, "You want to use Europa to hit Mars again?" "If Ye Chen wants to obtain water through impact again, it is not impossible, but the Martian surface they have just modified will be destroyed again.

Ye Chen shook his head, Europa may contain a lot of life, Ye Chen didn't want to completely destroy Europa.

"No, I want Europa to be a moon of Mars, which would both stabilize the axis of rotation of Mars. It can also create a better environment for life on Europa, and as for how the water on Europa flows to Mars, I have my own way, so you don't have to worry about this. ”

Coming out of the zod spacecraft, Ye Chen once again came to the orbit of Jupiter, after losing Io here, it seems that nothing has changed, Io's small size is almost insignificant compared to the behemoth of Jupiter.

It's the same process as transferring Europa. Ye Chen calculated in detail the coordinates of Europa's most suitable orbit in the spacecraft, and after everything was completed, he built a wormhole again and migrated Europa from Jupiter's orbit to the Martian orbit.

Moment. Europa is pulled by the gravitational pull of Mars and moves in a predetermined orbit, which changes the orbit of Mars, but everything is within the range of the computer's calculations. For the rest of the long years, Europa will follow Mars on its orbit around the solar system, just like the Moon and Earth.

Europa enters orbit around Mars. Huge sunlight shone into Europa's cold surface, and Europa had never seen such a strong light since its birth, and for a moment, the cold ice began to melt and turn into clear water.

However, at this time, Europa did not have an atmosphere, and as soon as the sea water was generated, it evaporated directly under extremely low air pressure and became part of Europa's atmosphere. However, this process does not last forever, until Europa's air pressure meets the conditions for the presence of liquid water, and the gasification process naturally stops.

In an extremely thin atmosphere, the sun heats Europa very quickly, and the sea above the ice is already tens of meters thick and boiling.

"If this continues, the sea layer will become thicker and thicker, and the remaining heat of sunlight will become weaker and weaker, so that it will be difficult for the ice under the water to melt again." Ye Chen pondered for a moment, "Let's start now, Europa's water source, enter Mars!" ”

Ye Chen took out the green light ring, put it on his hand, and called on the energy in the green light ring, and a spiral wormhole with a diameter of about 50 meters appeared in the Ganymede sea layer, and the other end appeared on the towering mountains of Mars. The reason why he chose to be on the mountain was because Ye Chen wanted as much of the surface of Mars as possible to be watered by water.

Ye Chen tried his best to control the oval shape of the wormhole, so that under the limited water surface, a larger contact area could be obtained, and at this time, the wormhole had expanded to a length of one thousand meters.

In an instant, a relentless and endless stream of water flowed into the wormhole, gushing out on Mars at the other end of the wormhole, and the moisturizing water flowed through the dry surface of Mars, bringing hope for life.

Under Ye Chen's frantic extraction, Europa's sea gradually began to become shallow, and the strong sunlight projected in again, greatly speeding up the speed at which Europa's ice melted.

However, Europa's ice is about 50 to 100 kilometers thick, and it will not melt in a short time, but the amount of water contained in it is twice as large as the sea water on Earth, which is enough to meet the needs of Mars.

On Mars, Zod stood outside the porthole of the spaceship and waited quietly, he had probably guessed what Ye Chen wanted to do, so he didn't follow Ye Chen, estimating that now there was almost a big flood on Mars.

"Look, General, over there!" At this moment, Fura looked out of the porthole of the spaceship in surprise, and saw that on the horizon not far away, a raging tide was rapidly coming, and it would not be long before the ship could reach here.

"Let's wait, I'm afraid this flood will last for a long time!" Zod said calmly, Mars has just been born, and the surface is still emitting amazing heat, just as this global flood has swept over, which can bring life to this parched land, and countless water vapors will evaporate, rise into the air, and then transform into a global heavy rain, washing away the dust in the air.

After these things, it is time to ionize the water source and inject a large amount of oxygen into the planet, and when the time comes, a new and vibrant Mars will finally be born. (To be continued......)
