The structure of the creatures on this planet seems very simple. Some of them are like those with an abnormally low degree of evolution in the Cambrian. There are no vertebrates at all.


    In the process of dissection, no myelin sheath was found in the neural network of these organisms. The so-called myelin sheath is a protective layer wrapped outside the nerve, which is a unique equipment of vertebrates.


    It''s like a wire. A wire wrapped with insulation is better than one not wrapped. The same is true of nerves. Nerves wrapped in myelin sheath can increase the transmission speed of electrical signals by a hundred times, from one or two meters per second to one or two hundred meters per second.


    It is the existence of this layer of myelin sheath that makes vertebrates ascend the throne of hegemony in the biological chain, because among all organisms, only mammals can add attributes to their body shape without limitation.


    Other creatures are more than one meter in size. The brain sends a command, and the body takes one second to receive the command. It''s very bulky. Even if an ant can grow as big as a man, you can calmly go around his back and attack his fragile abdomen, because their nerve transmission speed is too slow to turn around.


    As for the robotic Zerg on the moon, it''s another matter. The neural lines of silicon-based organisms and carbon based organisms are completely two things.


    However, now the following things, nerves must have a higher level of evolution, otherwise a body close to 10000 meters long cannot be so flexible.


    Chengying tries to communicate and probe the mental power into the other party''s brain. In a moment, the huge and terrible mental power kicks back. If it hadn''t been for his millions of years of Taoism, he would have been extinguished by this spiritual force in an instant. Even so, he felt a burst of chest tightness and poor breathing.


    It was the first time for him to feel that his mental power was suppressed. In the past, he was the most powerful in Douluo continent. But in front of this guy, his mental power was as fragile as a baby, almost broken as soon as he touched it.


    Fortunately, the other party didn''t mean any harm. The impact just now was because someone suddenly communicated with him. He was too excited.


    It is only today that we found that the strength of spiritual power is closely related to the volume of the brain. The big guy below, the diameter of the brain is afraid to be hundreds of meters, and the volume is hundreds of millions of times that of the shadow. Naturally, he also has much stronger spiritual power than the shadow.


    "Who are you? How did you get to this planet? Do you still have soul power? Sorry, I have nothing to entertain you. Are you from a planet in orbit 3? Do you have company? How''s the third orbit planet? " A series of questions asked the filmmaker dizzy.


    The other party''s mental strength is too strong. It''s like shouting with a square dance trumpet in your ear. It''s so shocking that the camera''s brain is buzzing. If anyone else on Douluo mainland comes, I''m afraid they''ve been shocked.


    "Sorry, can you keep your voice down? My brain can''t stand it." The film studio can''t stand each other''s enthusiasm. It seems that this guy hasn''t spoken for too long. It''s not easy to meet a guy who can communicate and say everything.


    "Sorry, I have been here for so many years. I have no soul power, so I have to cultivate my spiritual power. I don''t have a good sense of propriety. Do you have any companions? There is no soul power here. Can you fly back to the planet in the third orbit? "


    From between the lines of the big guy, the undertaker heard that the guy was probably from Douluo, so he asked in turn, "do you also get the planet from the third orbit? When did you get here? How did you fly here? "


    The big guy in the water patted his tail fin and set off a huge wave. He didn''t care what the film set him. Now he just wanted to talk to someone, so he kept talking:


    "I was originally a Kunpeng of the third orbital planet Jean. I usually live in the sea. My favorite food is Orca and deep-sea squid. Sometimes I turn into birds and fly to land to catch diamonds and mammoths. Their meat is very chewy, but it''s a little stuffed."


    Background: "


    With this guy''s size, how on earth do little guys like diamond mammoths plug their teeth? Put the whole head between his teeth?


    Kunpeng seemed to see the doubt of the background film and explained: "at that time, I was not as big as I am now, probably... Well, in your familiar unit of measurement, it was about 70 or 80 meters in size, and a bird should have a 100 meter wingspan.


    At that time, nothing on the mainland was my opponent. Your race, uh... You were a little like a monkey, but why didn''t you have hair? In short, your race was still picking fruit from trees at that time, because you were too small, so you were not within the scope of my prey.


    I have lived on that planet for hundreds of thousands of years! In fact, it''s quite boring. Besides eating and sleeping all day, I occasionally bully deep-sea demon whales and evil killer whales.


    After a long time, I felt bored when I was invincible on the mainland. I once flew around the earth under my feet and knew that there was a ball under my feet. I wanted to go outside the ball.


    So I tried to fly out. At first, it was very difficult. The soul force in the high altitude was thin and it was very difficult to fly. After trying for hundreds of years, I found a little trick. I flew more with the power of wings and rushed out of the atmosphere for the first time.


    There is no soul power there. I feel very uncomfortable, but my feathers can well isolate the soul power and ensure that my soul power is not lost. Therefore, I can move outside the atmosphere for a long time.


    You know, the eagle''s eyes are very powerful. As a Kunpeng, my eyes are even more powerful, so I saw other planets. At that time, the nearest planet to me was the planet in the fourth orbit.


    After observing his trajectory for more than ten years, I determined his operation rules. I wanted to go and have a look. I thought there would be interesting creatures on other planets. On this planet, I was too bored, so I made some preparations, reserved a lot of soul power, found a chance to fly past the nearest fourth orbit planet.


    You know what? I''ve been flying for five years. In those five years, I''m just bored and crazy. There''s nothing around. I can only fly. My soul power is consumed a little. Fortunately, I have stored a lot of soul power, which is enough for me to fly to the fourth planet. I think I can supplement my soul power there. Since I can fly here, I should be able to fly back.


    But when I flew here, I found that the problem was big. There was no soul power here, and the planet was extremely desolate. My soul power had been exhausted and had to land here, but I found that I couldn''t fly back.


    You should know that in space, there is no air, and even if I beat my wings hard, I can''t accelerate. Without soul power, I can''t even change my direction! "
