It stands to reason that the water of this lifeless underground lake should be clear, but in Liu Yu's eyes, it is a little turbid.

Liu Yu hurriedly used his divine sense to probe into the lake, and in the lake water, Liu Yu's divine sense found a large number of microorganisms, and the largest was the size of a sesame seed.

At that moment, Liu Yu is energetic, there are these microorganisms in the lake water, so the entire underground lake water definitely has a complete ecological chain, which circulates endlessly.

First of all, Liu Yu's divine sense swept towards the level of the underground lake to see how large the area of the underground lake was.

After a long time, what surprised Liu Yu was that the entire underground lake water level was more than 3,000 meters long and more than 1,000 meters wide, and the more you went down the lake, the wider it was below, and the creatures inside also became larger, the entire underground lake was more than 800 meters deep, the bottom was 10,000 meters wide, and there were many dark rivers under the lake.

At the bottom of the lake, Liu Yu did not find large organisms, there were just clusters of plants similar to seaweed, about ten centimeters high, they feed on the excretion of microorganisms in the lake water, and finally these plants release oxygen to nourish the energy needed for microbial activities, and these lakes also contain a large amount of various organic substances, which come from the substances in the rocks and soil impacted by the water flow in the dark river.

Liu Yu is still very curious about the dark river in Mars, and one is whether this underground lake is the only underground lake on Mars.

Then Liu Yu's divine consciousness extended towards a relatively large underground dark river.

The water flow of the dark river is very gentle, even ordinary people can easily swim upstream, Liu Yu estimates that the source of the dark river is countless small tributaries.

In the dark river, Liu Yu found a number of creatures, they were half a centimeter in size, a bit like a cockroach, their shells were very smooth, and they looked hard, and those creatures were clinging to the stone walls of the dark river to gnaw on the rocks, which was also the reason why Liu Yu found that there were a large number of dense holes in the passages in the dark river.

Liu Yu's Divine Consciousness continued to advance towards the Dark River, and when it was about fifty kilometers, his Divine Consciousness came to a wide underground space, which should be an underground lake, but it was much smaller than the underground lake where Liu Yu was.

There are still many dark rivers in the underground lake here, some large and some small, leading to all directions, and cockroach-like creatures have also been found, and some other microorganisms, Liu Yu estimates that the entire Martian underground lake is like this, and the largest creature is only half a centimeter in size.

Half an hour later, Liu Yu passed through the dark river and found no less than ten underground lakes, the range of underground lakes is still very vast, thousands of kilometers long, and the reason for the flow of water is the time of the planet's autobiography, turning backwards, turning upside down, and flowing like that repeatedly.

Mars is alive, but it is all life without intelligence, and even the ecological chain is very fragile.

In the end, Liu Yu collected hundreds of cockroach-like creatures into the dark river in the small world with a wave of his hand, but he didn't know what would happen to them in the world where materials were abundant and they had aura.

Then he was ready to return to the Martian surface, and then removed the two shields, leaving one shield, and as time passed, the last shield would collapse because of no energy, and it would take about ten years, and after returning to the ground, Liu Yu sealed the entrance.

Then Liu Yu was going to see what kind of human face stones, Martian skulls, Martian fossil fish, ancient Martian statues, and similar pyramids on the earth, to see if it was artificially created or nature's magic.

Liu Yu's divine sense can spread thousands of kilometers, which is very easy to view any object, Liu Yu found the skull, fossil fish, human face stone, god statue, and did not find a trace of artificial traces on it, there is a big difference between closer viewing and distant abstract viewing, these things are the result of nature's nature.

In the end, Liu Yu rushed to the north of Mars, where there is the Martian pyramid, according to the 1972 Meiguo "Mariner 9" spacecraft in the exploration of Mars, in the Eliji Plateau area of Mars, found a group of strange-looking behemoths. From a distance, these objects resemble pyramids with a quadrangular base.

In 1976, the American "Viking 1" spacecraft photographed buildings similar to Egyptian pyramids in the Kidoni region of the northern hemisphere of Mars.

Nine kilometers from the building, the spacecraft also took a startling photo. The photograph clearly shows a relief of a person's head. The relief is 1,500 meters long and about 550 meters high. It looks up at the sky silently, giving it a mysterious and unpredictable feeling.

Soon, Liu Yu flew towards the Martian pyramid, and when he was far away, Liu Yu did see the so-called pyramid on Mars, and it was spectacular.

When he flew above the pyramids, Liu Yu landed on the top of the pyramids, because I don't know when these pyramids were formed, they may also have weathered, and there are no artificial traces on the surface, just like an ordinary stone.

In the end, Liu Yu used his divine sense to probe inward from the top of the pyramid.

The inside of the pyramid is completely solid, and when Liu Yu's divine consciousness spread to the inner kilometers of the earth, he did not find any internal space, and there were traces of artificiality inside, and the entire pyramid was as a whole, nor was it accumulated piece by piece, which can show that Mars also had no intelligent creatures in ancient times, and no aliens came to Mars to build the pyramid, which is a small regret, for the time being, it seems that human beings are very lonely in the universe.

In the end, Liu Yu was ready to stay on Mars temporarily, and when his strength became stronger, he went to the Kuiper zone, which is in the outermost part of the solar system, and Kuiper is composed of many meteorites with a size of more than 100 kilometers, and there are 30 astronomical units closest to the sun, which is about 4.5 billion kilometers away.

Then Liu Yu made a hole in the pyramid of Mars, preparing to stay here for a while.

The entire pyramid was carved out of a space of hundreds of cubic meters by Liu Yu, and then the entrance of the cave was sealed, releasing a lot of fresh air and some plants from the small world, which can be regarded as a simple temporary residence.

Liu Yu thought that after waiting for many years, people came to the Mars exploration pyramid and there was a hollow inside I don't know what to think, and finally found traces of inhabitation inside, it is very interesting to think about, maybe this is another historical unsolved mystery.

It took Liu Yu to fly from the earth to Mars in the early years of the year, which means that 10,000 years have passed in the small world, and during this time, Liu Yu has occasionally checked the changes in the Continent of the Gods, but he has not had time to take a closer look.

No, Liu Yu's thinking came to the small world again, and then took over the clone Heavenly Dao.

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

Thanks to 2018~2019~ long-legged beauty, Fu Tianhong rewarded 100 starting coins, thank you very much, and thank you Xiong's life reward of 500 coins, and Hu Wei's reward.

(I remember seeing the name Hu Wei when I wrote the first book, and the avatar is the same, it feels like fate 😂)

I've been writing for more than a year, and I'm still on the street for almost two years, and I'm also helpless, maybe I don't have a talent for writing!
