After Liu Yu entered the universe, he felt that his body was completely weightless. It was as if he was swimming in water. It was very relaxed.
Liu Yu, who was in outer space, was surrounded by endless darkness and could see endless starlight in the distance.
(The protective shield produces its own air)
Earth was as beautiful as in a sci-fi movie, giving people a huge visual impact.
After taking one last look at Earth, Liu Yu turned around and headed toward his goal.
He did not know if he would be able to return to Earth in the future.
Perhaps many years later, when he thought of Earth, it would be his "hometown".
When he was in outer space, Liu Yu had also removed the protective shield. He could feel all kinds of rays passing through his body and endless coldness.
However, Liu Yu's body had been strengthened many times by the origin. It was very powerful. All kinds of rays and radiation could not hurt Liu Yu's body at all.
If an ordinary person entered space without the protection of a spacesuit, the atmospheric pressure in the body would quickly expand due to the universe's vacuum environment. It would cause the lungs to rupture and enter the body's circulatory system, leading to death in 20 seconds.
Liu Yu's current body was very strong. Whether it was his bones, skin tissue, internal organs, or cells, they were all super tough. The atmospheric pressure in the body could not spread at all.
Of course, after Liu Yu left Earth, he still set up more than ten protective shields around himself. The largest effective protective shield spread to a radius of 500 meters.
The function of the protective shield was to prevent meteorites from hitting him.
Not only did the protective shield protect his body, but Liu Yu's divine consciousness also fanned out in the direction he was going. It was a million meters long.
With the divine consciousness warning of a million meters, Liu Yu had enough time to avoid even a high-speed meteorite.
In fact, the divine consciousness of the Star State could only scan a distance of 100,000 meters in the small world.
However, Liu Yu was different. Because Liu Yu had been sleeping in the core space of the small world for 10,000 years, the speed of his divine sense's growth was naturally very fast and very powerful.
The universe was dark and full of all kinds of rays. At the same time, it was also a lonely and silent universe.
When Liu Yu was tired of flying, he would also stop. His mind would enter the Small World to observe all living beings, so as to alleviate the boundless darkness.
Just like that, Liu Yu reached the expected orbit of Mars after a year. Then, he didn't have time to watch Mars from outer space.
Because Mars was moving rapidly, if they missed it, they would have to wait for many years before they could meet Mars again.
As soon as Liu Yu entered Mars, he felt gravity, some water molecules, and the dust that filled the sky. Liu Yu guessed that now was the time when the Martian sandstorm would erupt. His luck wasn't very good, but Liu Yu didn't take it to heart. A small sandstorm naturally wouldn't make Liu Yu worry.
Mars was only a quarter the size of Earth, with a diameter of nearly seven thousand kilometers.
Like Earth, Mars had various landforms and environments. In the north of Mars, there were low plains filled with lava, and in the south, there were ancient highlands full of craters. The two were separated by obvious slopes, interspersed with volcanic terrain, and many canyons were scattered everywhere. At the north and south poles, there were polar caps composed of dry ice and water ice, and sandstorms covered the entire planet.
People in the 21st century had always guessed that there was life on Mars in ancient times and tried to find evidence, but not many people believed it.
There were also people who had been looking for evidence of microbial life on Mars. For example, the thousands of dry rivers on Mars were all topics of interest.
In fact, Liu Yu was also very curious about whether there was life on Mars, whether it was microorganisms or multicellular organisms.
Liu Yu now landed in the South Pole of Mars.
According to Liu Yu's understanding, there was dry ice in the South Pole of Mars. Scientists even proved the existence of underground water or an underground lake.
There was indeed dry ice in the South Pole, and it was very cold. As for the situation underground, it needed to be investigated.
Immediately, Liu Yu's consciousness spread out from his brain and spread to the inside of the earth under his feet.
One meter, five meters, ten meters, and thirty meters were all frozen soil layers. At forty meters, there was no frozen soil, but there were very few water molecules.
At one hundred meters underground, the water molecules increased further, reaching the moisture content of the air in the desert on Earth.
There were no microorganisms in this area, and at most, there were some stones.
When Liu Yu's consciousness spread to three hundred meters inside the earth, he still didn't feel the existence of liquid water. Then, he continued to spread, but there were still no microorganisms or water. So, Liu Yu gave up on continuing to investigate here.
Liu Yu remembered that NASA found an underground lake on Mars and confirmed the existence of water, and it was also in the South Pole.
Then, Liu Yu flew high in the sky and compared the location of the South Pole of Mars according to his impression of the picture.
About half an hour later, Liu Yu saw a landform that seemed to be sunken, similar to a lake. It was very obvious in the red landform of the entire Mars, because this lake-like landform had some white "salt" in it.
After Liu Yu felt that this was the position, he quickly landed and stepped on it, leaving footprints on it.
Then, Liu Yu spread out his consciousness again and explored the inside of the ground.
One meter, two meters, one hundred meters, five hundred meters. When Liu Yu was more than five hundred meters underground, he felt the wet soil.
Liu Yu felt that there was hope. There might really be an underground lake in this place.
When Liu Yu's consciousness spread a thousand meters underground, he found that the soil had begun to become wet. If he squeezed it with his hand, he might squeeze out water.
Suddenly, Liu Yu's consciousness relaxed. It was water, liquid water.
In the observation of Liu Yu's consciousness, when he was 1,700 meters underground, he found a huge space. The whole space was filled with liquid water.
Liu Yu also seemed a little happy at this time. He finally found an underground lake.
The reason for his happiness was that he could live for a long time, so he had to find something to do, right?
On one hand, he was the first person on the whole earth to see liquid water on an alien planet, and he could immediately come into contact with that liquid water.
The soil layer was 1,700 meters thick. Even with the current technology, it was a huge project to open such a deep passage on the earth.
Of course, the method Liu Yu used was the simplest method, which was to directly put the soil into the small world. This was just a matter of thinking.
Swoosh, swoosh, swoosh, a square of soil was put into the small world by Liu Yu.
The passage was sloping, which was convenient for him to move.
The entire passage was circular, with a diameter of three meters.
Ten minutes later, Liu Yu had opened the passage to a depth of 1,690 meters, and then Liu Yu stopped.
Because Liu Yu was afraid that when he broke through the underground lake, because of the pressure in the internal environment, there may be a lot of liquid water rushing to the sky from the passage.
In this outer space, where there was a lack of water, the underground liquid water was very precious. Even if he couldn't use it, he had to consider the future development of human beings to establish a colony on Mars.
Otherwise, why would Liu Yu make a circular passage with a diameter of three meters?
So Liu Yu arranged three protective shields in the passage to isolate the passage from the outside world.
Then Liu Yu opened the whole passage, and the whole passage was connected to the underground lake.
Liu Yu snapped his fingers, and a dazzling flame appeared on Liu Yu's index finger, illuminating a small area of space.
The water level of the underground lake was not full, and it was five or six meters high from the underground space.
At this time, Liu Yu looked at the somewhat turbid lake water.
PS: Cough, cough, it's time to ask for a recommendation ticket again.
Here I would like to thank Star City Sky for the reward of 100 Qidian coins. Thank you very much, it made me more motivated to write.
Special thanks to the reader named "Mo Ming" in the QQ group. Today, he video-called me and said, "In the real world, the country released nuclear weapons in their own country, and using them to attack the protagonist might be banned. Also, he gave some opinions, it's really touching."
