Douluo see you

The spacecraft AI began to detect the surface environment of Mars. This time, the only person who landed was Cheng Ying. On the one hand, his strength is already very strong, and he does not particularly need guards. On the other hand, the five-element escape method is adaptable to various extreme environments The strongest, even if you throw him into the sun, you can still be intact.

In this aspect of interstellar exploration, the five elements escape method is undoubtedly extremely suitable.

"Detected atmospheric composition, oxygen content is 5%, nitrogen content is 70%, carbon dioxide content is 15%, and the content of various rare gases is 10%."

"Interesting? So much carbon dioxide? There might be life here." Chengying is not unreasonably guessed. There are a lot of free carbon elements in the atmosphere, which are likely to form the most primitive organic matter. Compared with silicon-based organisms, carbon-based Biology is obviously more realistic.

In addition, a large amount of carbon dioxide is also like the planet's insulation layer. Greenhouse gases envelop Mars, giving this supposedly extremely cold planet a relatively suitable temperature for survival.

The only flaw is that there is little oxygen, but oxygen does not affect the birth of life. The earth did not have much oxygen at first. If photosynthesis hadn't been pointed out, where did so much oxygen come from?

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 was highly toxic to them, which led to the mass extinction.

As for whether Douluo Xing has any experience in this area, Cheng Ying doesn't know it. Paleontology is a rather side subject. Tulips, who have been busy climbing war science and technology, have rarely dabbled in this area.

This time I came to the new planet. In addition to leaving the teleportation coordinates, it was to survey the surface of the planet. The current situation of Mars is actually very interesting. If some algae are thrown into the water body of Mars, they will be invasive alien species. I am afraid that it can multiply and absorb carbon dioxide in the planet's atmosphere and turn it into oxygen.

While retaining a certain amount of carbon dioxide to maintain the greenhouse effect, it does not seem impossible to transform this planet into a habitable planet.

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

Although synthetic food can provide the human body for survival, human beings have evolved a little bit at this step. The recipe does not mean that it can be changed by changing. The synthesis of trace substances contained in many plants and animals is extremely troublesome.

On the other hand, a habitable planet is also very beneficial to the development of the planet. There is no 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 prerequisite for doing this is to determine if there are any particularly terrifying creatures on this planet. After the shadow is near the landing site and leaving a teleportation coordinate, it jumps out of the spacecraft, flies at low altitude, and heads toward what is observed in space. The Great Rift Valley flew away, where there was tens of thousands of meters deep in the liquid water, and there was probably a large amount of creatures hidden.

It does not mean that a large size is necessarily strong. The wildebeest is not small, but it is not the opponent of the lion, but the individuals of single-celled organisms are undoubtedly weak.

If you want to have enough destructive power in the macro world, you must have a sufficiently complex body structure.

Chengying didn't wear any spacesuits, but just wore a casual outfit and flew low above 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. The gravity here is weaker than Douluo Xing, even less.

His landing place was next to the Great Rift Valley, and he quickly found the place of the Great Rift Valley. From the naked eye, the Rift Valley was still very spectacular.

From one end of the rift valley, you can't even see the other end. You must be in a state of extremely clear weather and high visibility before you can vaguely see the cliffs at the other end.

The rift valley is bigger, but it is not so steep. The flowing water and wind have carved the angular cliffs round, and the round cliffs seem to have been polished.

Chengying touched the damp place on the cliff and was a little surprised. It was a bit slippery. This was not the touch of an inorganic substance. He didn't carry a microscope with him, but with mental power, he still felt the cellular structure on the slippery thing. , Seems to be an algae-like organism.

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

But this is also normal. Oxygen is not a very stable substance. The high 5% of the oxygen in the atmosphere means that there is probably something that maintains the production of oxygen.

Looking down from the cliff, it is a pitch-black water surface. The underwater is not bottomless, like a gloomy abyss, which can swallow everything. Cheng Ying hesitated for a moment, jumped off the cliff, operated the water movement technique, and escaped into the water. Explore underwater.

The water in this canyon is salty water close to the composition of seawater, but it is relatively lighter. After all, the water body in the canyon has less evaporation than seawater.

Unsurprisingly, the ten meters of the surface of the water body is the most complex area of ​​biodiversity. There are a lot of strange creatures that have never been heard before, but these creatures are generally more casual.

Because there is no fierce competition, all living on the organic matter suspended in the water, everyone just grows like this.

The complexity of the species structure is relatively low, and it is far from the powerful life in Chengying's imagination. At least so far, there has not been a dominant species like vertebrates.

Even those similar to arthropods do not exist, each of them looks like suspended meat, which is really disappointing.

Just as Chengying was about to explore deeper and deeper, a sense of crisis arose spontaneously, making his back chill, and immediately he gave up his plan to go deeper and flew above the water.

He just got out of the water, and a huge mouth that was so huge that he was dizzy covered the area where he was just now. Just looking at that open mouth was a thousand meters in diameter, and the ghost knew how big this guy was.

The creatures in the area just now were swallowed by this big mouth, and the excess water was drained 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 10,000 meters, and probably only this tens of thousands of meters deep rift valley on Mars can accommodate him. .

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

It's just that no vertebrates have been found on Mars before. This big guy doesn't seem to belong to the biological chain of this planet. When he was puzzled, Chengying tried to communicate with the big guy.
