The interior of the spaceship wreck is not stuffy, the air is still fresh.

  Yan Mo speculates that the spacecraft will still have some functions at work. Later, he thought it was impossible. When he saw some moss and mushrooms growing in the corner of the interior wall of the spacecraft, he realized something.

  These plants are likely to absorb carbon dioxide and exhale oxygen. In addition, this is not a completely enclosed space. There must be some exits connecting the underground cave with the outside, and there are also exits in the underground city.

  After Xiao Sha took two turnes in the passage and bent into a doorway, there appeared a space about two football fields.

  The space is round, with a vacant space in the middle, surrounded by high walls that can hardly be seen their origin. There are honeycombed caves in the walls.

  The open space is full of sand. It's very comfortable to step on. Maybe the sand in the lower layer is very close. People will not fall into it when stepping on it.

  Unfortunately, the sand here is all polluted.

  His shoes are breaking down! These polluted sands can't even lspare of the cloth and dead fur!

  Yan Mo grabbed Xiao Sha and touches him several times.

  Xiao Sha was startled by his sudden move. "Hiss! What are you doing?”

  Yan Mo didn't have time to explain that he had put up the shield and that the amount might have gone very quickly.

  After making sure that he knew enough about the structure of Xiao Sha body, Yan Mo quickly backed away from him.

  "Hissing! What's the matter with you?” Xiao Sha chased him.

  Yan Mo has to be grateful for the clean habits of Chuan Shajias-the Sand Wearers. There is not a grain of sand on the ground. I don't know if these Chuan Shajias-the Sand Wearers also know the power of these polluted sands, so they won't be everywhere.

  "The sand makes me uncomfortable." Yan Mo is calm, and quickly used willpower plus life energy prayer: “May I have the ability to resist these pollutants."

  Just after Yan Mo's voice fell, his face and exposed skin suddenly grew scales like Chuan Shajias-the Sand Wearers.

  Xiao Sha now saw Yan Mo look more and more like Chuan Shajias-the Sand Wearers, and its wisdom is not enough for it to understand the change. It's just urging Yan Mo to move faster.

  Yan Mo raised his arm, looked at his scaly palm, raised his hand to touch his face, removed his protective cover, and stepped carefully into the sand.

  His shoes are gone, and his feet are covered with scales and thick claws.

  The sole of the foot is slightly immersed in the sand. There is no uncomfortable feeling coming from it, and the energy does not pass away at all!

  Succeed!

  A little Chuan Shajia came to see him. He seemed curious.

  This huge sand ground seems to be the playgrounds of the young Chuan Shajias-the Sand Wearers. Some of the young Chuan Shajias-the Sand Wearers scurried about in the sand and fight with each other.

  From time to time, the caves around the walls can be seen with the Chuan Shajias-the Sand Wearers going up and down.

  "Hissing. Don't be confused. Come with me. "

  Xiao Sha quickly climbed to the wall on the left, where there is a cave half buried by sand.

  Yan Mo took one step, another step, and his heart gradually became stable, as long as it has effect!

  When he walked into the caves, Yan Mo looked at them carefully and touched them with his hands. He guessed that these caves were probably the pipeline facilities of the spacecraft. He always felt that there was something under the sand layer, but now it's obviously not the time to explore.

  I don't know if it's Chuan Shajias-the Sand Wearers who occasionally found the occupation, or who put Chuan Shajias-the Sand Wearers here in the beginning?

  The pipe is not narrow, but it's clean. It's just that there will be some peculiar smell of Chuan Shajias-the Sand Wearers.

  The inside of the pipe is not all dark. Some places even emit light, but Yan Mo would not have looked into it.

  The most interesting thing is that some of these pipelines are roads, some are the houses of Chuan Shajias-the Sand Wearers, and there are some large spaces connected by the pipelines.

  Like where Yan Mo is being taken now.

  This is a place like a wastewater treatment pool, but now there is no water in it, only sand.

  There are also many pipes around the waste water pool, which they live in but Yan Mo didn't know at the beginning. After two hours, he realized that the residents here are all the old, the weak and the disabled of Chuan Shajias-the Sand Wearers. It's also warmer here than the pipes outside.

  "Hiss, you're too tall. You will live here for the time being." Xiao Sha stopped at the door of a small room that is half open and has some special purpose.

  Yan Mo looked inside, there is no light, but his eyes can see clearly. This is an empty small room without anything. There seem to be some lines on the wall, but it is impossible to distinguish what it is and what it means. On the whole, this small room is only about eight square meters high, about five or six meters.

  Xiao Sha bit his trousers and said to him seriously, "Hiss! Every Chuan Shajias-the Sand Wearers has to work. Although you saved me, I can't support you for nothing. I will provide you with shelter and food, but you have to work. It doesn't matter if you are disabled, but if you are lazy, people will drive you away, and I can't help you then. "

  Yan Mo smiled, Chuan Shajias-the Sand Wearers are semi intelligent creatures. Their language is not very rich. The hissing call contains some basic meanings. In order to understand conveniently, he understood the meaning conveyed by the other party according to his own language, so he was more used to it. According to Xiao Sha's expression, the social structure of Chuan Shajias-the Sand Wearers is very strict, and they don't like lazy people.

  "What am I going to have to do?" Yan Mo squatted down, reached out and stroked Xiao Sha again, this time in return for a friendship.

  Xiao Sha didn't want Yan Mo to touch him at first, but when Yan Mo's hand really touched it, its attitude changed. Ah, it's so comfortable. Touch me again!

  Yan Mo had to ask again.

  \r \r \r

  Xiao Sha squinted and said: "Hiss, you, you just touch me that’s not allowed! Your job is to help the Chuan Shajias-the Sand Wearers here get the old sand out of the cave and put new sand on it."

  Xiao Sha suddenly looked at Yan Mo: "Hiss, can you spray the net?"

  Yan Mo took a net bag out of the space.

  Xiao Sha went around the net. "Hiss. No, this kind of net hole is too big and has no viscosity, so it can't catch on the sand. "

  Xiao Sha was very sad, "Hiss! Why are you so useless? Even a qualified net can't be sprayed out."

  "What about a net like that?" Yan Mo took out a hemp bag.

  "Hissing! How can you spit out this kind of net? Well, maybe you're not that old.” Xiao Sha rolled some sand with his tongue and put it on the sack. As a result……

  "Hissing! You're still a loser! The net you blow out is useless. You can't even hold the sand!”

  Yan Mo didn't expect that Xiao Sha would experiment on the spot, so he had to make a sad expression of a disabled person. It's amazing that he can make himself out of the scales of Chuan Shajias-the Sand Wearers in a short time, but it will take a long time to fully assimilate the physiological structure of Chuan Shajias-the Sand Wearers to be able to spin and form a net. At least the life energy and willpower he has mastered now are still there not enough for him to do that.

  "Can you give me a sticky net? I'll repay you, brother!” Yan Mo begged.

  Xiao Sha hesitated. Their nets are very important to them, and their energy is consumed when spraying nets. It is said that every time the ancestors of Chuan Shajias-the Sand Wearers sprayed nets, their life span would be shortened. Although they are not so, a complete sticking net is very important to them.

  "Can't you?" Yan Mo's hand touched Xiao Sha's back again, and his voice was very soft.

  Xiao Sha was a bit pinched. He has been staring at Yan Mo for a long time. "Hiss, if you touch me later……"

  Yan Mo took it back. It's better not to promise things or not to promise things. "Can I exchange this with you?"

  Xiao Sha stares at the green spot on the tip of his finger and said, "Hiss! Want! Give it to me!” Before that, it was super greedy for this energy. Finally, this brother took it out again.

  Yan Mo exchanged life energy for a sticky net. Later, he had more contact with Chuan Shajias-the Sand Wearers. He knew that when an adult Chuan Shajias-the Sand Wearers sent sticky net to another Chuan Shajias-the Sand Wearers, it meant that he wanted to mate. If the other party accepted it, it means he agreed. Similarly, if there is an adult Chuan Shajias-the Sand Wearers who wanted to stick the net with another one, it is also the meaning of mating.

  Fortunately, Xiao Sha thinks Yan Mo is ugly and doesn't want to mate with him, otherwise Ha-ha!

  With this adhesive net provided by Xiao Sha friendship, Yan Mo has become an honorable member of the working group of Chuan Shajias-the Sand Wearers.

  It seems that Chuan Shajias-the Sand Wearers are really the bane of this pollutant. Their scales are the best protective armor, and their sticky nets can also net up the polluted sand without fear of damage.

  Yan Mo is assigned to help other Chuan Shajias-the Sand Wearers get the polluted sand out of the cave where the old, the weak and the disabled live, and then bring in new sand.

  The new sand can be taken from the seemingly waste water pool, which is now the sand pool. It should be noted that this kind of easy work is generally only done by the minors, while the adults, who do this kind of work, are generally recognized as the weak and the disabled. Because they don't need to go outside to get sand, it's the work of adult Chuan Shajias-the Sand Wearers to move new sand in from outside.

  Polluted sand can be poured into a circular pipe beside the sand pool, which will flow out along the pipe and return to the desert.

  Xiao Sha probably thought that it had found a place for Yan Mo, arranged a relatively easy job for him, and rescued Yan Mo from the enemy's hands. Its gratitude was almost repaid. He handed Yan Mo over to a leader like Chuan Shajias-the Sand Wearer here and left.

  The leader is a kind and middle-aged Chuan Shajias-the Sand Wearers. He doesn't discriminate against the deformity of Yan Mo. Even when several cubs surround Yan Mo and played around, he scolded those cubs.

  Mo, the newly deformed “Disabled and self-denigrated", packed a bag of sand into the allocated single room.

  Yan Mo is not allowed to work today. His first task is to build his own residence with new sand.

  Yan Mo has a headache looking at the sand. It looked white and greasy. In fact, it's all contaminated sand. If he gets the sand into his residence, it means that he needs to constantly maintain himself with Chuan Shajias-the Sand Wearers scales to ensure that he won't be engulfed by the polluted sand until he dies.

  But it also needs energy to maintain such a scale. Even if he is full of energy, it is not a long-term solution.

  So he threw the contaminated sand in the corner.

  The leader was a little worried. He whispered to his partner that the new one was a little strange. Although it was a big one, it was very weak. He asked to let everyone take care of it and let the children to not pick on it.

  Yan Mo heard it in the room, and his mouth twitched. Unfortunately, the half open door seemed to be unable to open and close. He pulled it, but he didn't pull it, so he had to leave it half open.

  He is not used to the darkness here, even if his eyes can see things naturally. He was also not afraid to be detected by Chuan Shajias-the Sand Wearers outside. He took four small lamp trees planted in the basin from the space and put them in four corners of the room.

  When the room lit up, Yan Mo felt a lot more comfortable psychologically.

  Outside the door, the little Chuan Shajias were exploring his head. He probably found the light of the room suddenly shining. These little Chuan Shajias were frightened.

  Yan Mo heard several cubs hissing for the leader.

  The leader came around, wanted to come in and hesitated. They are not afraid of light, but they do prefer night activities. The light of the lamp wood is very soft, but it is too bright in the completely dark space. No wonder those little Chuan Shajias are frightened.

  In the end, the leader left. They were united and lived together, but they would not interfere with other special behaviors of Chuan Shajias-the Sand Wearers, unless those behaviors would hurt other Chuan Shajias-the Sand Wearers.

  The leader stayed at the door for a while, and judged with his body that the shiny plants were not harmful. He was more curious about where the plants came from.

  The leader decided to report the matter to a higher leader.

  Yan Mo was going to stir up more high-level Chuan Shajias-the Sand Wearers, and it's best to lead them to meet him actively. In this period of time, he just went to study the energy destroying pollutants.

  In fact, it is not correct to say that these polluted sands have the function of swallowing energy. These pollutants are not swallowing energy, but destroying and decomposing the stable composition of energy, so that the destroyed and decomposing energy can be converted into another energy. Then the polluted energy can be absorbed again to maintain the pollutant own ability, it is just like living things.

  “Living things……" Yan Mo looked up and thinks about the components of the pollutants in the sea of souls that are analyzed by virtual machines.

  Is it possible that those pollutants are living things? Or some special alien bacteria?

  In fact, this is not incomprehensible. For example, when a spider catches a prey, it will first inject some digestive enzyme into it, causing the body of the prey to liquefy, and then the spider sucks the liquid.

  If we assume that this pollutant is also a living thing, then it destroys and decomposes the energy of the substance, is it not like injecting a special digestive enzyme into the energy containing the substance, making the energy “Gasify" and then converting it into a certain substance that it can absorb?

  By the way, Xing Hui once told him that when he was shot by an energy weapon, his wings were immediately "corroded" into a small hole, and that hole was still expanding. If he didn't dig out the corroded wing bone, his whole wing might be swallowed up.

  Yuan Zhan was also hurt by the energy weapon at that time, and also dug a piece of flesh.

  So can we judge that as long as there is energy, this “Living thing" - let's call it bacterium X, which will continue to reproduce by decomposing and absorbing energy, but once there is no active and abundant energy around, they will die out?

  If his prediction is accurate, is the desertification of this formerly rich land caused by the supply of these pollutants to increase?

  Maybe the original Bone Sculpting People didn't know how to extract and use this bacteria X. They just found that this kind of thing can destroy energy and make fertile soil into a desert in a short time.

  So when the Bone Sculpting People were forced to leave the eastern continent in a hurry, in order to protect their holy land, they deliberately created this energy to pollute the land around the underground city, not only making the surrounding land desertification, forming a suitable living environment for Chuan Shajias-the Sand Wearers, but also effectively preventing the possibility of creatures entering the underground city from the underground. Even in order to maintain the long-term existence of this material, they are likely to store a large number of yuan-crystals under the soil.

  But when the Bone Sculpting People released this pollutant, I'm afraid they didn't expect that the desert would gradually expand. Do they know the nature and strength of this pollutant?

  "Hiss, why don't you use sand? Are you afraid of the sand, too?” A very young hiss sounded.

  Yan Mo opened his eyes, and there was a significant difference between the hiss of adult Chuan Shajias-the Sand Wearers and that of young ones. The former was low or high, while the latter was a little sharp.

  The little Chuan Shajia, about half the size of Xiao Sha, poked through the open door and into the small half.

  Yan Mo waved to it, smiled, "come here." Children are always adventurous.

  The little guy is not afraid of him. He swishes and sniffs him. "Hiss, you're so strange. I've never seen Chuan Shajias-the Sand Wearer like you before."

  “Is that right?" Yan Mo held the little guy in his arms.

  The little guy struggled first, then became quiet quickly. He felt very comfortable in the arms of this strange partner. It used to climb over the backs of adult Chuan Shajias-the Sand Wearers only when it was very young, but it was the first time that it was held like this, and the little guy was very strange.

  Yan Mo followed the little guy's body and touched it thoroughly. "You just said that I'm afraid of the sand. Are there other Chuan Shajias-the Sand Wearers who are also afraid of the sand?"

  "Hiss, yes. They are relatively weak. If they touch the sand for a long time, they will die, and some will get sick.” The little guy bit the clothes on his body, which material seemed strange in.

  “Aren't some Chuan Shajias-the Sand Wearers sick and can't spray sticky nets?"

  "Hiss, do you do the same? You are pitiful. If you can't spray out the whole and useful sticky net, you won't find your spouse!” The little guy is worried about the strange little partner.

  No wonder Xiao Sha only called him a disabled, but not for his fear of sand. Even if he can't make a qualified sticky net, he just smirked, not vigilant.

  "Hiss, what's this in your cave? Why do they glow?"

  "Have you seen any plants that can shine? Just like those, they are bigger and brighter. "

  "Hissing! Yes, mushrooms that shine!” The little guy seemed to accept the explanation.

  The little guy's thinking leaped, and he quickly asked, "We have many strange looking partners. Some of them can survive, some will die soon, will you die soon?"

  "Oh?"

  One is interested in exploring, the other is curious, two are asking and answering, which is very pleasant.

  Yan Mo also named the little guy because he had a small scar on the corner of his eye, so he called him Little-Scar Shajia.

  Chuan Shajias-the Sand Wearers haven't developed the concept of name. They distinguish their partners by smell. Sometimes they prefix some special people, such as "The poor one who was born without scales", "The one who defeated ten sieges of Chuan Shajias-the Sand Wearers", "The one who couldn't find a mate", etc.

  Time passed quickly, Little-Scar Shajia crawled out of Yan Mo's arms and reminded him, "Hiss, come with me, it's time for dinner."

  From Little-Scar Shajia, Yan Mo learned that the Chuan Shajias-the Sand Wearers who live here don't have to go out to catch prey themselves, and the family will provide them with food, but rarely they will not do this, especially in winter, which is now winter.

  The place to eat is on the open space beside the sand pool outside. The Chuan Shajias-the Sand Wearers who live here line up very orderly to get their food.

  The food giver was the leader just now. The leader looked at Yan Mo and didn't say anything more. It just put the information up, but it didn't seem to attract the above attention. What they are worried about now is the winter food supplement.

  But the master is back. Maybe they don't have to worry about the food source this winter?

  Yan Mo lined up with Little-Scar Shajia. The order of receiving food here is from childhood to old age, from the healthy to the sick. The amount of food is almost the same.

  Yan Mo found that there are many diseased Chuan Shajias-the Sand Wearers here, some of which have obvious scales falling off badly. Little-Scar Shajia also told him that some of them are more seriously ill, and they can't get food by themselves, so they can only be sent to.

  Then, Yan Mo also saw the deformed Chuan Shajias-the Sand Wearers in Little-Scar Shajia's mouth - several Chuan Shajias-the Sand Wearers who have already had human appearance!

  Not only do their facial features look more like human beings, but their heads are also deformed, and they just bulge a piece behind the sharp brain tip. In addition, their upper limbs are more flexible and developed, and there is no web between their fingers. Their scales become smaller, thinner, denser and lighter in color. Their hind claws grow larger, and their tails are thinner, longer, softer and more flexible than other pangolins, just like the other legs.

  But these Chuan Shajias-the Sand Wearers are all weak without exception, and they are all juveniles, not an adult among them.

  "Hiss, see? Aren’t they similar to you? You must be the tallest of them

  Yan Mo's eyes were fixed on those mutated Chuan Shajias-the Sand Wearers, only he knew how excited he was!

  He actually saw an important node in the process of biological evolution!

  Just as the food team was moving slowly, one of the Chuan Shajias-the Sand Wearers suddenly fell to the ground.

  The companions around him were flustered and hissed.

  Little-Scar Shajia: "Hiss, see? Another one can't live. One died two days ago! There will be less food in the future. Maybe they can't survive this winter. "

  Yan Mo gave up the line, ran three steps and two steps, and said loudly, "Can I have a look?"

  The author has something to say:

  This chapter is rather complicated. I want to finish it quickly, but I am reluctant to give up these original storylines. Although I won't write about the war, the foreshadowing is very important, which is equivalent to an explanation: We are ready, and no one knows what the future will be, but we have the determination to protect our home and the confidence to win.

  I decided to write all the stories I wanted to write according to the original plan. Haha~~
