It's still sand under the sand. Yuan Zhan and Yan Mo walked on the bottom of the sand, and the sand in front of them receded with the steps of the two people as they walked forward. A passage that allows two people to pass side by side will appear in the direction where the two people pass and are about to go.

  To ensure safety, Yan Mo also made a shield for the two with willpower.

  "Chuan Shajias-the Sand Wearers generally live 30 meters or more below the sand layer, and their most livable sand layer is about 10 to 15 meters. If they go under more than the 30 meters, they will not be able to bear the pressure of the sand layer, and they will not be able to move freely. If they go over 35 meters, they will not be able to move." Yan Mo said as he walked.

  Yuan Zhan consciously walked underground. They plan to see what's under the desert before meeting Chuan Shajias-the Sand Wearers.

  "These sands……" Yan Mo grabbed a handful of sand and puts it to his nose and sniffs. "Did you smell it? A strange smell. "

  Yuan Zhan also grabbed a handful of sand and rubbed it. “It's mixed with things, not like ordinary sand."

  "You mean the sand doesn't form naturally?"

  "Yes." Yuan Zhan seems to know how to distinguish whether the soil is naturally formed or artificially prepared. Previously, Yan Mo asked him to prepare some soil with special ingredients. Now, he can detect the difference in any soil basically by touching it.

  Yuan Zhan face suddenly changed color. He threw away the grains of sand. It doesn't count if he threw them away. He also smashed the one in Yan Mo's hand, "Throw them away! They can drain up energy!”

  Yan Mo also noticed that, but he didn't throw it immediately, but he was asking for The Guide info. However, The Guide only told him that the sand was a composite of unnatural items, which was not within the scope of The Guide.

  Yuan Zhan cautioned, "These sands give me a similar feeling to those energy weapons. Let's walk around and have a look."

  Yan Mo thought, "We won't know without direct contact, but if we contact these grains of sands directly, they will consume our energy. We can separate the grains of sand, but the animals can't. No wonder those insects and animals were not willing to come to this desert. Only the rat king is willing to lead the way, but also refuses to enter this desert. This desert is not small.” From the sky, it's almost five times the size of Jiu Yuan city.

  They walked around the bottom of the earth and found that the sand layer with strange smell was just more than 30 meters, and it was just around the boulder on the ground, that is, the periphery of the underground city formed an irregular circle which composed of the abnormal sand formation.

  Yan Mo thought, squatted on the ground and drew a picture, with a small circle inside the big circle.

  "The small circle represents the underground city and the big circle represents the polluted desert. Do you see anything?"

  Yuan Zhan said, “If this underground city is really what you said the Bone Sculpting People left at the beginning, then they also made this circle of polluted desert?"

  Yan Mo got up. "It’s very likely. This underground city may be very important, so it was not enough for the Bone Sculpting People to leave only Chuan Shajias-the Sand Wearers who watch the house and protect the yard, and they decided to pollute the surrounding land. They were afraid that even some creatures will attack the underground city from the underground."

  "You mean the Bone Sculpting People deliberately turned this land into a desert in order to create an environment for Chuan Shajias-the Sand Wearers to live in?"

  “More than that. There is also a problem with the sand quality of this desert. Have you noticed that there is almost no plant in this desert?”

  "The sand can absorb energy. What plants can live here?"

  "Chuan Shajias-the Sand Wearers haven’t wondered why only they can live in this polluted desert. How do they get into the underground city? Is there a safe passage?”

  “I'm more curious about how the Bone Sculpting People can make such grains of sand?" Yuan Zhan sneered.

  Yan Mo raised his finger. He caught something in his head.

  "Spaceships, energy weapons, remains of the underground city, the Bone Sculpting People, grains of sand, Chuan Shajias-the Sand Wearers. Give me some time to ponder them!”

  Yan Mo closed his eyes, his consciousness sank into the Soul Sea and appears directly next to the Dragon Blood Tree.

  Yuan Zhan closed his eyes when he saw the priest had gone to the ancestors again, so he went to take him into his arms.

  Once again, the half of the land opposite the Dragon Blood Tree has changed greatly. It used to only put some simple pharmaceutical tools, but now it has become a super modern laboratory.

  Looking carefully, this laboratory is exactly the same as the second one.

  Yan Mo, a medical lunatic, used a lot of willpower + life energy + belief points to copy the whole second laboratory.

  Although everything here is virtual, but because of the life energy, their actual use is exactly the same as the real laboratory. Here, Yan Mo can do a lot of experiments without increasing SCUM VALUES.

  The young sapling was sitting on the bookshelf reading with its legs up. When it saw him come in, it puts its hands to greet him.

  Yan Mo hailed it, changed the previously touched contaminated sand and began to test it.

  Little sapling threw the book aside, jumped down, and jumped to Yan Mo. He seemed very interested in what Yan Mo was going to do.

  Yan Mo also intended to cultivate the young seedling into his own lab assistant. While testing, he will tell him the reasons and steps for doing so, and also tell him to do some small things, such as taking the test tube and pressing the button.

  Little sapling never had such a good time.

  The test results came out.

  These grains of sand are indeed polluted, but the pollution source does not belong to the material on this planet, because the instruments here cannot distinguish its composition.

  Yan Mo thought about it, got out the energy gun and went to the Dragon Blood Tree.

  “Break it down for me."

  It took a thousand faith points to break down energy guns, not many.

  Yan Mo immediately agreed to put the energy gun into the mouth opening of the Dragon Blood Tree.

  The Dragon Blood Tree swallowed the energy gun and spit out a pile of parts in a short time.

  The parts were all floating in the air. Besides the parts, there are some familiar text of Yan Mo, introducing the names and functions of these parts.

  “Found it!" Yan Mo grabbed a cystic part, which felt very hard and translucent like a yuan-crystal.

  \r \r \r

  Yan Mo gave the capsule and sand to the Dragon Blood Tree, "Tell me if they can eat the same energy."

  The number of faith points needed this time is very high, up to 5000.

  Yan Mo agreed without blinking an eye.

  The result of the analysis is that Dragon Blood Tree told Yan Mo: The components of the sand grains, both of which make the energy consummation are the energy weapon.

  Dragon Blood Tree can't analyze like an instrument, it can only tell Yan Mo the results.

  If the energy weapons cause the same components of energy to be consumed as the pollutants contained in the sand, then why Chuan Shajias-the Sand Wearers who can live freely in the polluted sand

  Thinking of a possibility, Yan Mo's heart rate accelerated, he quickly quit the Soul Sea and opened his eyes.

  “Let’s go to Chuan Shajias-the Sand Wearers! I may know the reason why this underground city is important!” Yan Mo regretted that he didn't ask Chuan Shajias-the Sand Wearers before.

  They only glided in a circle of sand 20 meters deep.

  The Chuan Shajias-the Sand Wearers are really here. Maybe they can't fight in a small number. Thousands of Chuan Shajias-the Sand Wearers surrounded Yuan Zhan.

  It seems that they are surprised that there are creatures that can move in the sand and have not died. In the past, as long as the creatures fell into this desert are dragged into the ground by them for about one meter, no matter how powerful they are, they can only die after a few moments.

  These Chuan Shajias-the Sand Wearers found that their claws could not deal any damage to Yuan Zhan, and they forced him to run in one direction.

  Yuan Zhan followed them and dragged Yan Mo to the underground city.

  Yan Mo looked back at those Chuan Shajias-the Sand Wearers. He now looked at these Chuan Shajias-the Sand Wearers, just like he looked at any treasure, and his saliva will flow out. Maybe their future hope lies in these ugly little monsters!

  The Chuan Shajias-the Sand Wearers in the back don't know what they have done. Running in the sand, Yuan Zhan suddenly felt the front sink. He pretends that he can't stop and slid down the sink.

  “Poof!" Yuan Zhan and Yan Mo fell on a pile of sand.

  "Shua Shua Shua." A large number of Chuan Shajias-the Sand Wearers fell from above.

  Yuan Zhan held Yan Mo and rolled down from the sand.

  This is an underground hole!

  The place where they fell is like a movable pedal hole. When those Chuan Shajias-the Sand Wearers fell, the pedal returned to its original state, and the sand did not fall any more, only a sand pile was formed under the pedal.

  Although their eyes can see things in the dark, the complete darkness will still have a certain impact on that. In the dark, countless small yellow lights were lit, which are those Chuan Shajias-the Sand Wearers!

  Yan Mo stealthily took out the torch from the space and hands it to Yuan Zhan for lighting.

  There was a little commotion in the group of Chuan Shajias-the Sand Wearers.

  “Poop poop!"

  Without waiting for two people to look at the underground void, thousands of Chuan Shajias-the Sand Wearers suddenly spit out a large number of sticky nets, forming a huge capture space.

  All sides are nets, even on the ground. Ordinary warriors can't escape at all.

  The two men have shields, and the mesh doesn't stick to them, but it's not easy to get rid of them.

  The sticky net is very strong and sticky. It can't be torn off or swept away. When it's stuck to the body, it will not only be restrained, but also the skin will feel burning.

  Yuan Zhan thought that this kind of sticky net could be solved by burning it. But he soon found that the sticky net could not be burned. When it was burned, black and blue smoke rose, and an unpleasant smell came to his nose.

  "Hold your breath!" once Yan Mo smelled the smoke, he realized that it was wrong. It was like the burning of plastic multiplied by three times the smell of scorching. It was disgusting and dizzying.

  Yuan Zhan has held his breath for a long time. He didn't need to breathe through his nostrils when walking under the ground. “Are you sure?"

  Yan Mo knows what he's asking and pushed him gently, “I'm ok, you go first. Let the people above block all the exits. Don't attack before you receive my signal, especially don't take the initiative to hurt these Sand Wearers. "

  Yuan Zhan pretended to be dizzy. He burnt a road in all directions. When he is about to go out, he acted as if he was supporting Yan Mo. Then he disappeared in this underground hole.

  These Chuan Shajias-the Sand Wearers probably also know that Yuan Zhan is difficult to deal with. They didn't chase after people when they are driven away. Their main purpose is to rescue the ugly and weird little friend with two long feet (Yan Mo). When they see that they have rescued the little friend, they were very happy.

  The first Chuan Shajias-the Sand Wearers learned how to climb to Yan Mo's feet and bite his trouser legs, "Hiss." Come with me.

  Yan Mo was thinking about how to shuttle through the sticky net in the full space, but stopped when he saw the Chuan Shajias-the Sand Wearers start licking the sticky net on the ground and around them.

  "Hiss." Don't waste it. Do it like us. The brothers Chuan Shajias-the Sand Wearers greeted him.

  Yan Mo: “.…… I cannot."

  Chuan Shajias-the Sand Wearers: "Hiss!" you are such a rare waste. Come on, you wait here.

  Yan Mo stood at the same place, watching Chuan Shajias-the Sand Wearers lick and lick, and soon all the nearby sticky nets were eliminated.

  That's not all. The industrious Chuan Shajias-the Sand Wearers have finished sticking the net, and then they go to deal with a Little Shajia. He saw that they are throwing out the sticking net together again, pulling the little Shajia and dragging it out.

  There are also passages in this underground cavity. A large number of Chuan Shajias-the Sand Wearers dragged the little Shajia one by one and disappear from the passage.

  At last, only Yan Mo and the Chuan Shajias-the Sand Wearers were left in the underground cavity.

  Yan Mo decided to call the little Shajia Xiao Sha for convenience. [1] Xiao means Little Sha means Sand

  Xiao Sha greeted Yan Mo and asked him to follow him.

  Yan Mo thought that the passage of Chuan Shajias-the Sand Wearers were very narrow. He really found it when he walked through there. At first sight, those passages were artificially paved and sealed with rocks. In other words, the underground cavity was more like digging through the original rock layer.

  No, walking along, Yan Mo found that this is not a rock layer that has been dug through, but the original huge underground cave, which has been transformed manually.

  Who could have thought there was such a huge underground cave under the thick desert?

  Yan Mo heard the sound of water flow and understood the reason why Miao Xiang and others could survive in the desert underground city.

  With such a large underground karst cave and rich groundwater resources, Yan Mo can almost imagine how rich a piece of land the ground was thousands of years ago. Unfortunately, after man-made damage and pollution, the richer land in the past has become a desert, and even grew trend of expansion.

  Expansion……

  Yan Mo thought about the polluted sand layer. If the pollutants can devour the energy, can they also devour the energy contained in the land? Will the original polluted soil layer not be so large at first, only after tens of millions of years of evolution, will it expand to the current level where it managed to spread? If the time is longer, the polluted sand layer originally hidden in the ground is blown around by the wind, then the land far away will be……

  Yan Mo shuddered!

  He walked into the underground cave for about half an hour.

  "Hiss." Xiao Sha turned around and signaled that they have arrived.

  Yan Mo looked up and forward, dumbfounded.

  How can Yan Mo not recognize the creation in front of others?

  Although the shape is a little beyond imagination, it should be the tail of some kind of huge spacecraft?

  Almost a small city wide and a large spaceship has a black tail poking out, which was slightly obliquely inserted in the rock layer. Its cross-section was embedded in a black rock, including the black stonework on the hull.

  Another ship! Or did the Ding Yue find the same as the one here? But how many parts did that one break?

  No wonder the Bone Sculpting People attach so much importance to this underground city. Yan Mo couldn't help but wonder if the civilization origin of the Bone Sculpting People would be related to the objects found in the ship?

  In his mind, he could not help drawing a picture: A group of wild people with long horn on their forehead found the wrecked ship, because of its unique shape or some residual functions, these wild people with horns thought it was a God.

  So the Horn savages worshipped it and began to explore the wrecked ship.

  Later, some people found some strange tools and items, they may just feel they looked funny at first, but slowly found that they are also very easy to use. So the wisdom of these Horn savages was enlightened, and they began to imitate the appearance of these instruments with bones.

  With the passage of time, the wisdom of Horn savages is also accumulating. Maybe they have finally cracked something, maybe they have found something similar in nature, so bone objects civilization was born

  Tens of millions of years later, because of the war, the Horn-people were kicked far away from their hometown and their holy land. They could not take the spaceship, nor wanted it to be found. They polluted the land and migrated the Chuan Shajias-the Sand Wearers, who were suitable for living in the desert, to guard the spaceship for them, leaving instructions for future generations.

  Unfortunately, the inheritance of the Bone Sculpting People has also been lost. The Horn-people have forgotten the holy land, or they have not forgotten, just don't know the clear direction? Just like they don't know where the inheritance hall is in the eastern continent.

  Yan Mo suddenly thought that the desert is not far from the Jiu Yuan, and the straight-line distance is about seven or eight hundred kilometers.

  Yan Mo suddenly squatted down and began to draw a map. He first marked the underground city, followed by the inheritance place under the Tiangui mountain stone column. Then he drew a line between them, and then he looked to the land to the west of the line. There was the Ding Yue tribe on a large plain there.

  Yan Mo wrote something, pointed a little to the west of the two points, and an equilateral triangle appears.

  "Hiss." What are you drawing? Xiao Sha patted him gently with his tail.

  Yan Mo chuckled and wiped out the simple map with his feet. “Nothing, you live here?"

  Looking down, there is a deep cave entrance at the lower end of the tail of the spacecraft.

  At the entrance, there are Chuan Shajias-the Sand Wearers crawling in and out.

  "Hiss." Come on, don't worry. I'll protect you. Xiao Sha is very righteous, saying that Yan Mo can depend on his help in the future.

  Yan Mo smiled and followed Chuan Shajias-the Sand Wearer into the cave.

  The cave entrance is narrow, and Yan Mo needs to bend down to enter. But the space inside is not small. As soon as you enter, you can see an artificial wide channel.

  Yan Mo touched the edge of the wall, not the rock, not the soil. It should be the inside of the spacecraft.

  “May my eyes see everything in the ground."

  As soon as the low noise falls, the original blurred vision immediately became clear and incomparable.

  Yuan Zhan went to the ground to explain what Yan Mo ordered, and told everyone that the sand layer is dangerous. Don't step into the ground again.

  This time he went down to the bottom of the earth about fifty meters, completely avoiding the sand above.

  He didn't worry about Yan Mo, so he decided to go to the underground city to investigate, but he would be more careful when he knew that there were dangerous substances that could devour energy.

  Miao Xiang did not leave the dungeon at last.

  He is full of strange confidence in this place, as if he is determined that no creature can easily enter here.

  Strange to say, he is familiar with the underground city, but doesn’t know why he is familiar with it.

  He knows that he has lost a very important part of his memory, but it doesn't matter. As long as he is still alive, everything is still hopeful to be recovered.

  Although some of his memories are missing, there are many useful things in his memory. For example, he knows where to look for the ancestral tree of yuan-crystal, where there are treasures, and knows the underground city.

  He has been studying the underground city these days, and he can now enter the fourth floor underground.

  From his memory, the underground city seems to have 12 floors. He knew that there were some very important treasures in the underground city, but he could not go down and he didn’t remember what those treasures were, which made him a little anxious.

  In particular, the scouts heard that the people of the Jiu Yuan had reached the outskirts of the desert and could enter here at any time.

  "Don't worry, they can't come in. Even if they come in, we don't have to be afraid of them.” He stroked his box like weapon and smiled at his subordinates.

  “Tell those insect be ready to kill as soon as they find foreign enemies!"

  "Yes."

  After his subordinates left, he immediately got up and entered a small door. He wanted to summon Chuan Shajias-the Sand Wearers and tell them something.

  [1] Chuan Shajias-the Sand Wearers would look almost like this……
