After Liu Yu entered the universe, he felt that his body was completely weightless, just like swimming in the water, very relaxed.

Liu Yu is in outer space, surrounded by endless darkness, and can see endless starlight in the distance. (Protective cover produces its own air)

The earth is as beautiful as in science fiction movies, giving people a huge visual impact.

After taking one last look at the earth, Liu Yu turned around and headed towards the goal.

I don't know if I will be able to come back to Earth in the future?

Many years later, when I thought about the earth, well, it was my "hometown".

When he was in outer space, Liu Yu also removed the protective shield, and he could feel all kinds of rays passing through his body, as well as endless cold.

However, Liu Yu's physical body has been strengthened by the origin many times, and it is very powerful, and all kinds of rays and radiation cannot harm Liu Yu's body in the slightest.

If an ordinary person enters space without the protection of a spacesuit, it will soon be because the atmospheric pressure in the body is greater than that of the vacuum environment, the atmospheric pressure will expand rapidly, causing the lungs to rupture, and then enter the human circulatory system, which will lead to death in twenty seconds.

Liu Yu's current physical body is very strong, whether it is bones or skin tissue, the internal organs in the body, including the cells, are super tough, and the atmospheric pressure in the body cannot be spread at all.

Of course, after Liu Yu was far away from the earth, he still arranged more than ten protective shields around himself, and the largest effective protective shield spread to a size of 500 meters.

The function of the shield is, naturally, to prevent oneself from being hit by a meteorite.

Not only was a protective shield protecting the physical body, but Liu Yu's divine sense was also fanning in the direction of his advance, and its length reached a distance of millions of meters.

With a million-meter divine sense warning, even a meteorite traveling at high speed, Liu Yu also had enough time to avoid it.

In fact, the demigods in the small world of the Star Realm's divine consciousness can scan a distance of 100,000 meters.

However, Liu Yu was different, because Liu Yu had been sleeping in the core space of the small world for 10,000 years, and the growth rate of his divine consciousness was naturally very fast and powerful.

The universe is a dark, ray-based universe, but at the same time a lonely, silent universe.

When Liu Yu is tired of flying, he will also stop, and his mind will enter the small world to watch sentient beings, so as to alleviate the boundless darkness.

In this way, Liu Yu reached the expected orbit of Mars after a year, and then he didn't have time to watch Mars in outer space.

Because Mars is in rapid motion, if you miss it, you don't know how many years it will take to meet Mars again.

As soon as Liu Yu entered Mars, he felt a sense of gravity, and some water molecules, as well as the gray layer in the sky, Liu Yu estimated that now is the time for the Martian sandstorm to erupt, and his luck is not too good, but Liu Yu didn't take it to heart, a small sandstorm naturally won't let Liu Yu take it to heart.

Mars is only a quarter the size of Earth and nearly 7,000 kilometers in diameter.

Mars, like Earth, has a variety of geomorphological environments, from lava-filled lowlands to ancient highlands filled with craters in the north, separated by obvious slopes, interspersed with volcanic terrain, numerous canyons, and polar crowns of dry and water ice at the north and south poles, with wind-blown sand throughout the planet.

People in the 21st century have been speculating that Mars had life in ancient times, and trying to find evidence, but not many people believe it.

In addition, some people have been looking for evidence that the current Mars is the existence of microbial life, such as the thousands of dry rivers on Mars, which are all topics of interest.

In fact, Liu Yu is also very curious about whether there is life on Mars, whether it is microlife or multicellular organisms.

The place where Liu Yu now landed is the South Pole of Mars.

According to Liu Yu's understanding, there is dry ice in the South Pole zone of Mars, and even scientists have proved the existence of groundwater or underground lakes.

There is indeed dry ice in Antarctica, and it is very cold, so as for the situation underground, it needs to be investigated.

Immediately, Liu Yu's divine consciousness spread out of his brain and spread to the interior of the earth under his feet.

One meter, five meters, ten meters, thirty meters are all frozen soil layers, and by forty meters the frozen soil is gone, but contains very few water molecules.

At 100 meters underground, the water molecules are further raised to the same level as the water content of the air in the desert areas of the earth.

There are no microorganisms in this area, and most of them are rocks.

When Liu Yu's divine sense spread three hundred meters into the interior of the earth, he still didn't feel the existence of liquid water, and then continued to spread without the existence of microorganisms and water, so Liu Yu gave up and continued to investigate here.

Liu Yu remembers that NASA discovered an underground lake on Mars and determined that there is water, and it is also the Antarctic zone.

Then Liu Yu flew in the sky, comparing the position in the south pole of Mars according to the pictures in his impression.

About half an hour later, Liu Yu saw a landform that seemed to be sunken, similar to a lake, and he was very obvious in the entire red landform of Mars, because this was similar to the landform of a lake, and there were some white things like "salt".

After Liu Yu felt that this was the position, he hurriedly landed and stepped on the footprints one by one.

Then Liu Yu spread out his divine sense again and surveyed 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 damp soil.

Liu Yu felt that there was a drama, and there might really be an underground lake in this place.

When Liu Yu's divine sense spread thousands of meters underground, he found that the soil had begun to get wet, and if he pinched it with his hands, he might squeeze out the water.

Suddenly, Liu Yu's consciousness relaxed, it was water, liquid water.

In the observation of Liu Yu's divine sense, when he was 1,700 meters underground, he found a huge space, and the entire space was filled with liquid water.

Liu Yu also seemed a little happy now, and finally found the underground lake.

The reason for being happy is that you can live for a long time, so you have to find something to do, right?

The first person on the earth to see liquid water on an alien planet was the first person to have access to that liquid water right away.

The 1,700-meter-thick layer of soil is a huge project to open such a deep passage on the earth with current technology.

Of course, the method used by Liu Yu is the simplest method, that is, it directly talks about the soil being collected into the small world, which is just a matter of moving thoughts.

Whoosh, a square of dirt was collected into the small world by Liu Yu.

The passage is sloping, which is convenient for self-movement.

The entire passage is circular in shape and three meters thick in diameter.

Ten minutes later, Liu Yu had already hit the passage to a distance of 1,690 meters, and then Liu Yu stopped.

Because Liu Yu is afraid that when he penetrates the underground lake, because there may be pressure in its internal environment, countless liquid water may rise from the channel at that time.

In this water-deficient outer space, this underground liquid water is very precious, even if you can't use it, but you have to consider the development of human beings to establish colonies on Mars in the future, right? 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 link between the passage and the outside world.

Immediately, Liu Yu opened the entire passage, and the entire passage was also connected to the underground lake.

Liu Yu snapped his fingers, and a dazzling Origin Flame appeared on Liu Yu's index finger, illuminating a large range of space.

The water level of the underground lake is not full, and it is still five or six meters high from the underground space.

At this time, Liu Yu looked at the somewhat turbid lake.

PS: Ahem, it's time to ask for recommendation votes again.

Here I would like to thank Star City Sky for the reward of 100 starting coins, thank you very much, it makes me more motivated to write.

Special thanks to the reader called "Last Name" in the QQ group, and today he also called a video to me and said, "The reality of the writing, the country will release nuclear weapons in its own country, and the things used to hit the protagonist may be blocked, and I also put forward some opinions, which is really moving." ”
