That's all. Chapter 208, Extraterrestrial Life

However, even if he was interested, Li Yuanshan did not start exploring the universe immediately, because it was almost the time of the Chinese New Year, and he had to go to the furniture store.

Everything was normal, Yang Mingdong and a few people came back on the twentieth day of the first month, Li Yuanshan bought some souvenirs and took them home with large bags and small bags.

A few days after returning home, Li Yuanshan and the two began to explore the universe.

Out of the solar system, there are planets around Proxima Centauri, choose one as a foothold, and then continue on. The Milky Way is a large galaxy with as many as 120 billion stars, and most of the stars near the center are older stars (such as white dwarfs), while the outer regions are young stars.

The Sun is just one of the many stars in the Milky Way, and it stands to reason that since life can appear on the Earth around the Sun, there should be many stars older than the Sun, and so many planets around the stars, there should be many life like the Earth, and much earlier than the Earth. Then, the time for the emergence of highly intelligent life like human beings will also be much earlier. However, the two explored and observed many planets, but found nothing.

However, the two did not have the idea that the Earth was the darling of the galaxy, and the planets they explored were just a drop in the ocean.

After more than eight months of continuous exploration, the souls of the two did not know how many planets they had visited, and finally discovered that there was life on one planet!

"Hahaha...... After looking for so long, I finally found it!" Li Yuanshan's soul excitedly transmitted his thoughts, "This is the first living planet outside the earth! This shows that the earth is not the only one, there are many living planets in the universe!"

This is a planet that revolves around a star that is much farther from the center of the Milky Way than Earth, young stars, young planets, and low-end life, primitive and backward but thriving.

Jiang Mingyue was also very happy, after all, this was another planet with life. After being happy, Jiang Mingyue said: "Hundreds of millions of years ago, more than a billion years ago, the earth should be like this!"

"Pretty much. Li Yuanshan felt everything on the planet and sighed: "The vitality of heaven and earth here is so strong! If you practice martial arts here, you don't have to work hard, and you can easily break through the innate nature." ”

"The earth should have had such a strong heaven and earth vitality, you say, before us, there were people who reached or even surpassed our realm. Jiang Mingyue said thoughtfully, "It's just because the Heaven and Earth Yuan Qi has been consumed too much and has become thinner that you left the earth?"

"I wish I had, but it shouldn't be. Li Yuanshan thought for a while and said, "When the vitality of heaven and earth is strong, human beings have not yet appeared. After the appearance of human beings, the Heaven and Earth Yuan Qi must have dissipated and consumed a lot. Then the human race found the method of cultivation, and I don't know how long it has been. Although there were "Neijing" and "Su Wen" during the time of the Yellow Emperor, there were qi practitioners before the Qin Dynasty, and the qi practitioners were not just practicing internal strength! From past understanding, the cultivation method of internal strength was more refined and perfected in the Tang and Song dynasties. Even if there were really Qi cultivators before, their cultivation methods were very rudimentary, and it was almost impossible to attain. "Not to mention the difficulty of other processes, the genetic level can trap them to death. If Li Yuanshan didn't know about genes, the two would not have been able to break through. And although Li Yuanshan knew the genes, he couldn't observe them at that time, and what he could distinguish at that time was only at the level of cells.

After saying that, he began to take a closer look at the creatures on the planet.

The environment here is more primitive than the time of the dinosaurs, with large and small plants, but the structure is relatively simple. There are not many species of reptiles in the animals, but with their higher intelligence and stronger bodies, it is foreseeable that in the future, this will be their world, until new and higher species appear, but this time is very long. Think about how long the dinosaurs ruled the earth, if it weren't for the sudden extinction, after the emergence of human beings, there would have to be a long battle between the two sides before the dinosaurs would withdraw from the stage of history.

Soon, the two discover a fight taking place in one place. On the coast, a lizard-like reptile with a six-meter-long body and a thick tail covered from head to tail is hunting a fish more than three meters long.

Don't look at the small size of the fish, but the temperament is fierce, with the aquatic animal's fast swimming specialty, swimming quickly, opening the mouth full of steel teeth to bite.

However, since its opponents dared to prey on it in the water, they naturally did not come to send it to death. Its opponent was covered with scale armor, and although it bit the opponent's left hind foot, it could not bite through the scale armor, and did not hurt the opponent, but was thrown away by the opponent, and then was pulled by the big tail, and was bitten on the abdomen in a dizzy moment, and struggled for a while to die.

"Hehe, a master of light skills can't do a golden bell cover iron cloth shirt. Li Yuanshan's soul smiled.

"This big lizard also has a disadvantage, which is the abdomen. Jiang Mingyue said, "The lizard's feet are very short and can't protect its abdomen, if this fish attacks the lizard's abdomen, it can win." ”

"But this fish doesn't have this brain. Li Yuanshan said with a smile, "However, from this point of view, the future evolution direction of this lizard is either to shorten the length of the abdomen or increase the length of the limbs, otherwise there is only one way to go extinct." ”

As he spoke, another fight broke out in the distance. This time, it was still the lizard that was hunting, and the object of predation was a fish less than two meters long. Despite the fact that this fish is less than two meters long, it has a special feature, it has a sharp upper jaw that is nearly one meter long.

"Yo! This guy's pointed mouth is so good! Not to mention attacking the abdomen, even where the scale armor on the side of the attack is covered, the scale armor of the big lizard may not be able to block it. Li Yuanshan said with a smile, "I hope this fish brain is almost good, let's see whether the spear is strong or the shield is strong." ”

Although no one is smart in the fish's brain, after all, it has survived many battles, and its fighting instinct is very strong, so it will naturally look for the opponent's weak point to attack. However, as predators, lizards have more combat experience and do not give the billfish a chance to attack the abdomen.

In this way, the pipefish could not find a chance to attack and began to turn and flee. At this time, the pipefish realized that the opponent was not one, but two.

In desperation, the billfish frantically swung its fins and tails and turned in another direction to escape.

With a muffled "poof", the mouth of the sharpfish hit the side of the lizard that blocked it, penetrating the scale armor and piercing deeply into the lizard's body.

The lizard that blocked it was seriously injured, and under the severe pain, it howled "moo", and its body struggled violently and rolled over. The upper jaw of the pipefish pierced into the lizard's body, and it couldn't pull it out for a while, and it was rolled by the lizard, making it dizzy.

The lizard struggled for a while, and the pipefish finally broke away from the lizard, stabilized, and quickly left with its tail while the other lizard did not surround it.

"It hurts!" Li Yuanshan said with a smile, "This mouth is powerful! It seems that not only is it necessary to increase the length of the limbs and shorten the abdomen, but this scale armor also needs to become stronger, otherwise it will be unbearable to put on a mouth." This lizard is finished, with such a serious injury, even if it would not have died, the same kind of people will not let go of this opportunity. ”

Sure enough, when the badly injured and exhausted lizard came ashore, it was greeted by a lizard of about the same size. The battle ended quickly, and the lizard was easily bitten off its neck and fell to the ground to die. The abdomen was torn open and the flesh was eaten.

Stayed on this planet for a long time, observing the flora and fauna on it. Li Yuanshan's soul imagined: "If these species are brought back to Earth, I don't know how much of a sensation it will cause!"

"If you haven't brought the space here, how can you bring it back?" Jiang Mingyue said, "Moreover, these animals and plants may not be able to survive if they are brought back, after all, the environment is too different, and the pollution on the earth is not small." Also, it's better not to bring it back, we don't care, but what about the others? Who knows how much disaster they will have if the viruses and bacteria they carry go to Earth!"

"That's right. Li Yuanshan said, "Not to mention viruses and bacteria, these things really can't survive on the earth, and the climate and environment are too different!" As for pollution, the most typical is DDT. DDT, whose chemical name is bis-p-chlorophenyltrichloroethane, is a chemically synthesized insecticide with good insecticidal effect, which began to be used in large quantities during World War II. But then it turned out that this kind of thing is very difficult to degrade and has a very large impact on living things. Moreover, with biological activities and water cycles, it has spread to the whole world, and even in Antarctica, which is far away from the land where humans live, the presence of DDT has been found in penguin blood. Ten years ago, when the two of them caught fish at sea and put them in the space, it was easy to clean up the pollutants in the fish, but when they returned to the village, it took some time to promote the decomposition of DDT, and they cleaned it up every once in a while. Now the village probably has the lowest DDT content in the world.

After observing for a while, the two made a note of the location and continued their search. This time, the two plan to search for the center of the galaxy, hoping to find a planet where there is a higher level of life, or even a civilization or civilization that surpasses that of the earth. After all, the closer to the center of the Milky Way, the longer it takes for stars to form, and only when the formation time is similar or even longer than that of the Sun and the Earth, the time for life to appear will be longer, and there will be a greater chance of the emergence of human or humanoid intelligent life and the formation of civilization.

However, this is too difficult to find, and I encountered several planets with life along the way, all of which have not yet formed primate life, and even one planet that has just formed single-celled organisms.

Continuing to explore inside, they came to a star about a third closer to the center of the Milky Way than the Sun, and the two stopped in surprise.

What surprised the two of them was that there were unnaturally formed things on several planets around this star! For example, on the planet where they are now staying, in addition to a few buildings that have been covered with large transparent covers, there are also many mines.

Although these buildings appear to be unnaturally formed, everything is destroyed, and not a single life has been found, not even the simplest single-celled life.
