The spacecraft AI began to detect the surface environment of Mars. Only the photographer landed this time. On the one hand, he is already strong and does not need special protection. On the other hand, the five element escape method has the strongest adaptability to various extreme environments. Even if he is thrown into the sun, he can be intact.


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


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


    "Interesting? So much carbon dioxide? There may be life here. " The background is not groundless speculation. There are a large number of free carbon elements in the atmosphere, which is likely to form the most primitive organic matter. Compared with silicon-based organisms, carbon-based organisms are obviously more realistic.


    Moreover, a large amount of carbon dioxide is also like the planet''s insulating layer. Greenhouse gases wrap Mars, so that this supposedly extremely cold planet has a relatively suitable temperature for survival.


    The only defect is that there is little oxygen, but oxygen will not affect the birth of life. The earth did not have much oxygen at first. If photosynthesis had not been pointed out, where would there be 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 had no experience of living in an oxygen environment. Oxygen was highly toxic to them, which led to the mass extinction of organisms.


    As for whether douluoxing has experience in this field, it is unclear. Paleontology belongs to a rather eccentric discipline. Tulips, which have been busy climbing war technology, have little involvement in this field.


    This time I came to the new planet, in addition to leaving the transmission coordinates, I was surveying the planet''s surface. Now the situation of Mars is actually very good. If some algae are thrown into the water body of Mars, as alien invasive species, they may be able to reproduce in large quantities, absorb the carbon dioxide in the atmosphere of the planet 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 the planet into a livable planet.


    The value of a livable planet is much higher than that of the moon, which must hide in dungeons. It is more valuable just to engage in agricultural production.


    Although synthetic food can provide the needs for human survival, human beings have evolved a little after all, but this step can not be changed. The synthesis of trace substances contained in many animals and plants is extremely troublesome.


    On the other hand, a livable planet is also very good for the development of the planet. You don''t need to wear heavy spacesuits. You have to be stuffy in eating, drinking, Lasa and sleeping. There is no doubt that the work efficiency will be greatly improved.


    But the premise of doing this is to determine whether there are particularly terrible creatures on the planet. After the shadow is near the landing site and leaves a transmission coordinate, he jumps out of the spacecraft, flies at low altitude and flies towards the Great Rift Valley observed in space. There are probably large creatures hidden in the tens of thousands of meters deep liquid water.


    It doesn''t mean that a large size must be strong. The wildebeest is not small, but it is not the opponent of the lion, but the individual of a single-cell organism is 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 spacesuit, just wearing a casual suit and flying low on the surface of Mars.


    The lack of oxygen had little effect on him, and the difference in temperature and pressure had no effect on him. The gravity here was weaker than that of dolosine.


    His landing site is next to the Great Rift Valley. He soon found the location of the Great Rift Valley. 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 can vaguely see the cliff at the other end only when the weather is very sunny and the visibility is very high.


    The rift valley is large, but it is not so steep. The water and wind carve the angular cliffs round, and the rounded cliffs seem to have been polished.


    Chengying touched the wet place on the cliff and was slightly surprised. It was greasy. It was not the touch of inorganic substances. He didn''t carry a microscope with him, but with his mental strength, he still felt that there was a cell structure on the greasy thing, which seemed to be a creature similar to algae.


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


    However, this is also normal. Oxygen is not a very stable substance. As high as 5% of the oxygen in the atmosphere indicates that most of it exists to maintain the production of oxygen.


    Looking down from the cliff, there is a dark water surface. The underwater depth is not bottomed out, just like a dark abyss, which can devour everything. The filmmaker hesitated, jumped down from the cliff, operated the water art, escaped into the water and explored underwater.


    The water in this canyon is salt water close to the composition of sea water, but it is relatively lighter. After all, the evaporation capacity of the water body in the canyon is not as large as that of sea water.


    Unexpectedly, 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 unheard of, but these creatures generally grow casually.


    Because there is no fierce competition, they all rely on the suspended organic matter in the water to survive. Everyone can just grow like this.


    The complexity of species structure is relatively low, which is far from the powerful life imagined by the filmmaker. At least so far, no overlord like vertebrates has been seen.


    Even arthropods don''t exist. They all look like floating meat pieces, which is really disappointing.


    Just as the film was ready to explore deeper, a sense of crisis came into being, cooling his back. Immediately, he gave up his intention to continue to explore and flew over the water.


    He just got out of the water. A huge mouth that made him dizzy shrouded the area where he was just located. Just look at the big mouth with a diameter of kilometers. Who knows how big this guy is.


    All the creatures in that area were swallowed by this big mouth, and the excess water was discharged from a place similar to gills.


    Looking down from the sky, the thing below seems to be an extremely huge whale with a body length of nearly 10000 meters. Probably only the tens of thousands of meters deep rift valley on Mars can accommodate him.


    To be exact, such a big thing can no longer be called a whale, but should be called 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 the planet. When he was confused, the photographer tried to communicate with this big guy.
