?“ I thought a lot more than you thought, I calculated, with my current physical condition, it would be impossible to get out of this desert without a car, otherwise, by the time you came back here before, I would have already gone out of the desert alone.

And have you ever thought about it, I think the reason why Instructor Liu and the others were able to hand over the weapons to us so happily was because they were sure that even if the weapons were in our hands, they would be able to deal with us.

I still have a very strange feeling, I think Umbrella Stone Shuai should have called in rescuers, but I don't know why, they haven't shown up to rescue the two of us.

So don't think about other things yet, maybe for now, following them to go inside is the most correct choice. ”

"Are you sure?"

"I'm not so sure, but if you think about it, the last time I told you about the Inner Mongolia Absolute Yin Land, I just called Liu Cong, and they arrived two days later.

Although the time between is very short, whether it is manpower or material resources, Liu Cong is very well prepared, coupled with the time of driving to Inner Mongolia, it can basically be inferred that Liu Cong and they should have emergency personnel and materials and equipment to deal with this sudden situation. So after receiving my call, they were able to set off immediately, and they arrived in Inner Mongolia two days later.

I think after Umbrella Shishuai goes out, the first person he looks for should be Liu Cong, after all, only Liu Cong has the strength to fight against Instructor Liu, and only they can help us.

But don't you think it's strange this time? After Umbrella Shishuai left the ancient tomb, we stayed there for five or six days, according to common sense, Liu Cong and they should have appeared a long time ago.

But so far, they haven't heard from us at all, and I guess it's not that they haven't found us, but they've been secretly following us in the shadows, maybe now they're secretly following us in this strange passage, behind us. As long as we can reach the end of the tomb and find the treasures of this so-called ancient kingdom, by that time, it is likely that they will appear. ”

After hearing these words, Yang Lei was also a lot relieved. In addition to these reasons, in fact, Chen Ziyang had another reason that he did not tell Yang Lei, that is, about his left arm and the summoning of something in the depths of the passage.

But he knew that even if he told Yang Lei, it would be useless, but he might be tricked by Yang Lei, so it was better not to talk about it. Anyway, there's no better way to go now, so it's better to explore first.

Just as the two of them finished speaking, Instructor Liu shouted over there and told the two of them to hurry over.

Things are just as Chen Ziyang guessed, now in front of Instructor Liu, and in the center of this huge stone wall, there is an obvious groove trace. Taking out the diamond, Chen Ziyang adjusted the angle of the diamond, and then placed the diamond into this groove.

At the moment when the diamond was just embedded in the groove, a burst of white light suddenly flashed from the diamond, and these white lights instantly radiated out along the lines on the stone wall connecting the grooves, and all the lines on the entire stone wall lit up at this moment, and then there was a rumbling sound, with the groove as the center, a small stone door on the left and right sides opened back at the same time, and a huge entrance appeared on the stone wall.

Instructor Liu couldn't wait to walk in through the entrance, and the others followed. After crossing this huge stone wall, Chen Ziyang found that the ground here was very different from the previous sandy land.

With this huge stone wall as the dividing line, the floor of the passage behind the stone wall is all rocks, although there is still a lot of yellow sand on it, but it can be seen that these are just floating sand paved on the ground, and the real ground here is indeed rock.

"Eryang, have we crossed over? Is this door some kind of portal? How is it that once you pass through this gate, it seems that you are not in the desert? Looking at this sudden change, Yang Lei asked strangely.

"It's not surprising that deserts are formed by weathering rocks, and a lot of rocks are weathered to form a lot of sand, which is the desert.

To put it bluntly, in fact, the desert is a relatively thick layer of sand piled up together, if you dig all this sand, then there are still rocks under the desert, no matter how big and deep the desert is, it is impossible to escape this law, there is no desert directly to the center of the earth.

Generally speaking, the thickness of the sand layer in the desert is sixty or seventy meters, even if the sand layer of the desert where we are located is deeper, it is not deep, and the strange altar before blew away all the forty or fifty meters of sand above the ruins of the ancient country, and this depth is basically to the bottom of the desert.

In addition, it is very likely that the ancient kingdom was not built in the center of the desert, but on the edge of the desert, which was submerged by the desert that expanded later, so the sand layer above was not too thick.

Because of the blockage of this stone wall, the rock behind the stone wall weathers very slowly, and it is relatively well preserved, so this phenomenon will occur. ”

"You're a much better fool than me, and you can say anything to your mouth, although I don't know if you're lying to me, but your words convince me. It's a pity, if you kid go to talk about cross talk, it will be much more developed than now. ”

didn't go to fight with Yang Lei, but Chen Ziyang was thinking back to what he had just said. The main reason why the rocks here do not turn into sand grains is that the rocks here weather very slowly, but the obscuration of the stone walls alone should not have such a noticeable effect.

When he walked on the road in front of the stone wall, Chen Ziyang felt that the ground seemed to be a little harder, and in retrospect, it is likely that the surface layer of sand there was already very shallow.

Originally, this could be judged by the geological formations on both sides of the passage and at the top, but the three walls were all crawling with such strange plants, and he couldn't see what it looked like, so he ignored this point.

It seems that the deeper you go, the less weathered this passage becomes. What he said just now reminded Chen Ziyang, coupled with the strange change in direction of this passage, he had a rough guess, took out the compass, and after calibrating the direction, Chen Ziyang basically knew the reason for the weirdness of this passage.

After walking for a while, the plants on the three walls of the passage became thicker and thicker, and they were already the thickness of human thighs, and the roots of these plants were pressed together, one on top of the other, one on top of the other, one on top of the other, and the whole passage was narrowed a lot.

Xiao Ren, who was following closely behind Instructor Liu, suddenly stopped and stared at a root system on the side wall of the passage, and the other people were attracted by his strange behavior and all leaned over. It turned out that on this root, a spiky thorn-like object actually grew.

This spike is about the thickness of a person's thumb, a few centimeters long, and it is obvious that the spike grows directly from the root system of the plant, not embedded in it.

Although there are many roots of this plant in the place where everyone walked before, the surface of these roots is relatively smooth, and there are no such spike-shaped objects.

Xiao Ren stared at the spike on the root carefully, and then he reached over his finger and pressed it on the tip of the spike.

But no one thought that the spikes that grew from the roots of the plants were so sharp, Xiao Ren just touched it lightly with his fingers, and his fingers were pierced by the tip of this spike, and a drop of blood remained on the spike.

Under the pain, Xiao Ren hurriedly retracted his fingers and put them in his mouth to suck them. "Grandma, why is this thing as sharp as a stone needle!"

"Don't be too troublesome, what's so strange about a spike growing on a plant, hurry forward." Under the urging of Instructor Liu, the five people continued to walk towards the depths of the passage, and just as the five people had just left the spike, the drop of blood hanging on the spike was instantly absorbed.

After inhaling this drop of blood, the spike that grew on the root system actually grew slightly, and even the root system under the spike seemed to have a little more luster.

Because the air circulation in the passage is relatively poor, although the air here can make people breathe, but the whole passage is stuffy and unbearable, after walking for a while, all the people are sweating profusely, and they can no longer walk.

As the crowd advanced, the spikes appeared on the roots of these plants on both sides of the passage more and more, denser and longer. In the beginning, these spikes appeared only every few meters, but later the roots of the plant became thicker and denser, and even now, the root system of the whole plant is covered with such spikes.

As he was moving forward, Chen Ziyang had been paying attention to the pointer of the compass in his hand until the pointer pointed to the north again, and he said to everyone: "It's almost, I can't walk anymore, let's rest here today, I have something to tell you, I have figured out what this passage is about." ”

Although Instructor Liu was very anxious about the matter of this ancient treasure, after all, he couldn't eat a fat man in one bite, and after walking for a day, everyone's physical strength dropped very much, coupled with the stuffy air around him, he couldn't walk anymore, so several people sat on the ground together, and showed Chen Ziyang a look of please.

"When we first entered this passage, it was due north, but then I found that the direction in which we were going had changed, and until now the pointer on my compass told me that the direction we were going had changed due north again.

According to my guess before, this passage is arc-shaped, but because the arc is relatively small, and the field of vision is not good, we didn't find this. But now we've come full circle, but you see, we're still in the depths of the passage, and we're not back to where we entered the passage in the first place.

Since we passed the huge stone wall, there has been very little yellow sand, and the ground here is all rocky, which proves that the degree of weathering of the rocks here is relatively small. Generally speaking, the closer you are to the ground in the desert, the slower the weathering of the rocks will be due to the climate and geographical location.

It was the rocky ground that reminded me that there was only one plausible explanation for this, and that was that the passage was built in a spiral that went underground, like a winding road built on the tall peaks.

It's just the same as the arc of this passage, because this passage is too long, and the slope that extends downward is too small, so we haven't realized that we are actually going down. ”

After listening to Chen Ziyang's words, everyone lowered their heads and pondered for a while, and then they all nodded, agreeing with his statement.

"Although the structure of the passage is clear, I always feel that the passage is not as simple as it seems. I think it's time for us to exchange information, after all, such a large project seems incredible to me, and it would be very difficult to build it now, let alone two thousand years ago, and it was a sparsely populated ancient country on the edge of the desert.

The Art of War also says that if we don't fight unprepared battles, we just move forward so rashly, we are likely to encounter many unknown dangers, we are just a few people, if something really happens, we don't even have a chance to take care of each other, so I hope you don't hide your secrets at this time, and you can integrate all the information together, which will help us safely open the treasure of this ancient country. ”

When he said this, Chen Ziyang kept staring at Instructor Liu, and his words were addressed to Instructor Liu. After all, until now, he is the only one who really has a certain understanding of the treasure of this ancient country.

After thinking for a while, Instructor Liu said to Chen Ziyang: "It's not time yet, I'll say it when it's really time to tell you." ”

Seeing that his persuasion had no effect, Chen Ziyang sighed, and then pulled Yang Lei to a place far away from Instructor Liu to rest.

In order to prevent Instructor Liu from snatching the weapon back, after discussing it for a while, the two decided to take turns to rest, although neither of them would rest too well, but it was better than being a prisoner again.

Lying there, Chen Ziyang carefully recalled what had happened that day. Although there was no danger in this mysterious passage during this whole day, through the previous signs, he felt that the treasure of this ancient country was not simple, and it was likely that the danger would be very great.

And Instructor Liu is still hiding his secrets, and Chen Ziyang can't figure out why he has been reluctant to say, after all, he has followed him so far, and it is impossible to turn back, it seems that there are still many hidden secrets in this, and the truth may not be as simple as he thought.

After resting in the sweltering passage for a night, Chen Ziyang and Yang Lei dragged their tired bodies and continued to walk forward with Instructor Liu and the others.

After a while, a row of stone tablets appeared in front of the passage, only this time this row of stone tablets was not a single one, but composed of small stone tablets.
