Douluo live long see

The spaceship AI began to detect the surface environment of Mars. Chengying was the only one who landed this time. On the one hand, he is already very strong and does not need to be guarded. On the other hand, the five-element escape method is adaptable to various extreme environments. The strongest, even if he is thrown into the sun, he can still be intact.

In terms of interstellar exploration, the five-element escape method is undoubtedly very suitable.

"Atmospheric composition has been detected, oxygen content is 5.00%, nitrogen content is 70.00%, carbon dioxide content is 15.00%, and the content of various rare gases is [-]%."

"It's interesting that there may be life here with so much carbon dioxide." Chengying is not unreasonable speculation, there is a large amount of free carbon in the atmosphere, and it is likely to form the most primitive organic matter. Compared with silicon-based organisms, carbon-based organisms are obviously Be more realistic.

Moreover, a large amount of carbon dioxide is also like an insulating layer for the planet. The greenhouse gas wraps Mars, allowing this planet that should be extremely cold to have a temperature suitable for survival.

The only drawback is that there is little oxygen, but oxygen will not affect the birth of life. The earth did not have much oxygen at the beginning. If photosynthesis was not pointed out, where does it come from so much oxygen now.

The emergence of photosynthesis, in that ancient era, also led to a mass extinction of species. A large number of organisms did not have the experience of living in an oxygen environment. Oxygen is highly toxic to them, which led to a mass extinction of species.

As for whether Douluo Xing has any experience in this field, Cheng Ying is not sure. Paleontology is a rather remote subject, and Tulip, who has been busy with war science and technology, has little experience in this field.

When I came to a new planet this time, apart from leaving the teleportation coordinates, I just surveyed the surface of the planet. The current situation on Mars is actually very interesting. If some algae are thrown into the water of Mars as alien invasive species, they will I'm afraid it can reproduce in large numbers, absorb the carbon dioxide in the planet's atmosphere, and turn it into oxygen.

In the case of retaining a certain amount of carbon dioxide to maintain the greenhouse effect, it seems that it is not impossible to transform this planet into a habitable planet.

The value of a livable planet is much higher than that of the moon, a planet that must hide in dungeons. The value of being able to engage in agricultural production alone is high.

Although synthetic food can provide what the human body needs for survival, after all, human beings have evolved little by little, and the diet does not mean that it can be changed by changing. Many trace substances contained in animals and plants are extremely troublesome to synthesize.

On the other hand, a livable planet is also of great benefit to the development of the planet. You don't need to wear a bulky spacesuit, and you have to be bored in it when eating, drinking, and sleeping. There is no doubt that work efficiency will be greatly improved.

But the premise of doing this is to determine whether there are any particularly terrifying creatures on this planet. After Chengying left a teleportation coordinate near the landing site, he jumped out of the spacecraft, flew at low altitude, and headed towards the place observed in space. Flying to the Great Rift Valley, there are probably large creatures hidden in the liquid water tens of thousands of meters deep.

It doesn't mean that a large size is necessarily powerful. Wildebeests are not small, but they are not opponents of lions, but single-celled organisms are undoubtedly weak.

To have enough destructive power in the macrocosm, one must have a sufficiently complex body structure.

Chengying didn't wear any space suits, just wearing casual clothes and flying at low altitude on the surface of Mars.

The lack of oxygen has little effect on him, and the difference in temperature and pressure has no effect on him, and the gravity here is weaker than that of Douluo, so it's nothing.

His landing place was next to the Great Rift Valley, and he quickly found the location of the Great Rift Valley. Looking at it with the naked eye, the Rift Valley is still very spectacular.

From one end of the rift valley, you can’t even see the other end. You must have extremely clear weather and high visibility to vaguely see the cliff on the other end.

The rift valley is bigger, but it is not so steep. The flowing water and wind have carved the sharp-edged cliffs into roundness, and the rounded cliffs seem to have been polished.

Chengying touched the wet place on the cliff, and was a little surprised. It was a little slippery. This was not the touch of inorganic substances. He didn't carry a microscope with him, but with his mental strength, he still felt the cell structure on the slippery layer. , which appears to be an algae-like organism.

In other words, the oxygen content of the atmosphere here may have been rising.

But this is also normal. Oxygen is not a stable substance. The oxygen in the atmosphere is as high as 5.00%, which means that there is probably something that maintains the production of oxygen.

Looking down from the cliff, there is a pitch-black water surface. The water is bottomless, like a dark abyss, which can swallow everything. Chengying hesitated for a moment, jumped off the cliff, used the water movement technique, and escaped into the water. Explore underwater.

The water in this canyon is salt water close to the composition of seawater, but relatively speaking, it is a little lighter. After all, the water body is in the canyon, and the evaporation is not as large as that of seawater.

Unsurprisingly, the ten meters above the surface of the water body is the area with the most complex biodiversity. There are a large number of strange creatures that Chengying has never heard of, but these creatures generally grow more casually.

Because there is no fierce competition, and they all rely on the organic matter suspended in the water to survive, everyone can grow as long as they like.

The complexity of the species structure is relatively low, and it is far from the powerful life that Chengying imagined. At least so far, no hegemonic species like vertebrates have been seen.

Even arthropod-like ones don't exist, and each of them looks like a floating piece of meat, which is really disappointing.

Just when Chengying was about to go deeper and explore, a sense of crisis emerged spontaneously, sending chills down his spine, and he immediately gave up his plan to go deeper and flew towards the surface of the water.

He just got out of the water when a huge mouth that made him dizzy enveloped the area where he was just now. Just by looking at the big mouth that opened, it has a diameter of a thousand meters, who knows how big this guy is.

The creatures in the area just now were all swallowed by this big mouth, and the excess water was discharged from a gill-like place.

Looking down from the sky, the thing below seems to be an extremely large whale, a super big guy with a body length of nearly [-] meters, probably only this tens of thousands of meters deep rift valley on Mars can accommodate him to survive .

To be precise, such a big thing can no longer be called a whale, but should be called a kun.

It's just that there are no vertebrates on Mars before, and this big guy doesn't seem to belong to the biological chain of this planet, so doubts arose, and Chengying tried to communicate with this big guy.
