It was already dark when they followed the map and found the cave. The cave was indeed in a deep ditch, but Mo Yantian could not see any traces of the ditch being excavated by hand.

Could it be that I guessed wrong? But it is unbelievable that such a deep ditch suddenly appeared on this endless plain. Although he had some doubts about this, the reality of the situation did not allow him to think too much. This plain is unobstructed, and the cold wind gusts at night, and the few of them have been walking in the heavy rain for a long time, and their clothes have already been soaked, and it will be terrible if they are caught by this wind again. In addition, the few of them were exhausted from the fierce battle just now, and they urgently needed a place to rest. In other words, now I can only hide in that cave and make plans.

Mo Yitian led a few people to carefully walk down the deep ditch and came to the mouth of the cave marked on the map. The cave also appears to have been formed naturally on the surface. Upon entering the cave, he found it very dry, not at all like a tunnel leading to the bottom of the sea. But for now, drying is a good thing, at least don't worry about colds for everyone. The cave is large enough to accommodate more than a hundred people. Mo Beitian found a relatively flat place to sit down, he took out the igniter from his bag and prepared the haode firewood in advance to make a fire.

Laksin and the others sat down as well, and they took off their rain-soaked clothes and used the remaining firewood to build a stand to dry them against the edge of the fire. Mo took out dry food and distributed it to everyone and told them to rest early today and set off tomorrow to find the tunnel. Everyone was indeed too tired because of the day's fatigue, and they fell asleep after eating dry food. Mo Yitian wanted to study the map again at first, but he was too sleepy to do it, so he had to give up.

Nothing else happened that night, and Mo was the first to wake up after dawn. He sat up and leaned against a rock to study the map. It is clearly written on this map that there is indeed a tunnel in the depths of the cavern that leads to the bottom of the sea. It looks like you can get there by walking a little further.

Just as Mo was studying the map, Lakshin and the others also woke up. Mo Beitian briefly explained the analysis of the map he had just made, and he still thought that if he didn't get into the tiger's den, he would get the tiger, even if it was a trap, he had to give it a try. Rakshen and Xiao Xiao naturally agreed with Mo Yantian's idea, but the silly grandfather Situ Heshi always had a hippie smile on his face.

Mo is very helpless, and now it can only be like this. He also only wants to get rid of the pursuit of the Republic as soon as possible and return to the original village, where there may really be a good medicine for his teacher's illness.

After a brief breakfast, a few people packed their bags and continued on their way. The cave was much bigger than expected, and the road began to narrow a little further in. At this time, Mo Beitian, who was holding a portable flashlight, suddenly noticed that there was something strange about the surrounding walls. He looked closer and was taken aback, only to see that the stone wall was carved with all kinds of murals. Stylistically, these murals should have been made by different people, and the artists painted them at different times, but this is not the most shocking part, and the most inexplicable thing is that the scenes depicted in these murals are not the only ones that have been seen. Yes, they painted exactly the same thing as the one in that pyramid.

Mo Yitian handed the flashlight to Xiao Xiao in the back: "Look at what this is?" ”

Xiao Xiao was also taken aback when she took the flashlight. She'd seen it before, and though she didn't know what the scene in it meant, it would be strange for anyone to see the same thing in an unrelated place.

"Brother Mo, what's going on?" Xiao Xiao couldn't help asking.

Mo Beitian didn't answer him, because even he himself was confused, how could he explain it?

Xiao Xiao guessed Mo Yantian's mind after a few seconds, she didn't continue to ask, but silently returned the flashlight to him. Rakshen also came up at this time, and he glanced at the painting on the stone wall and walked away without looking back. In his opinion, there is no need to waste time on things that he can't understand, anyway, if someone is using his brain to think about these things, he doesn't need to participate.

Mo is the one who uses his brain, but he is wasting his brains. Such a clueless thing can only be put aside for the time being, and when the clues are clear, the truth will naturally surface.

Mo Zhitian knows this truth very well. He didn't dig any deeper, but chose to follow Lakshin and move on. In this way, the few of them quickly reached the entrance of the tunnel. It's a shame that this entrance is a dead end!

To be more precise, the so-called entrance was blocked by a door. This is a stone gate, and this gate is more than ten meters high. The door is carved with auspicious clouds and flying sky. Directly below the door was a beast's head, which was so hideous that it opened its mouth as if it wanted to devour everything that came near it. The joints of the doors are sealed with a cement-like substance, so that the air from the outside cannot enter and the air from the inside cannot come out. Now Mo Zhentian finally knew that this cave in Weishenme would be so dry. Originally, this gate blocked the air in the undersea tunnel, so that moist air with moisture could not enter the cave, so the distance from the cave entrance to the cave was relatively dry.

"Damn the gates! I've found it all here, but there's still nothing I can do! Mo cursed. He slammed the stone door with his fist incessantly, but the door just didn't move. There was no way, Mo had no choice but to retreat, and he began to observe the door carefully, hoping that this door could have a mechanism like the doors in the pyramid. It's a pity that after searching for a long time, he didn't find the mechanism to open the door. The only thing left to see was the beast's head. However, Mo Beitian didn't want to look at it anymore, because he knew that the beast head was actually a big lock, and the open mouth of the beast head was the keyhole of this door. But I don't have a key, so it's useless to just know the keyhole!?

Where can I find the key? Mo Beitian began to get anxious. As he scratched his cheeks, he suddenly thought of the clue Paul had left for him. The first three puzzles are solved, but there's one thing that doesn't come in handy, and that's the key! The reason why Mo Yitian thought of it was entirely because of the murals he saw along the way. He thought that since the scene depicted in the fresco was the same as that in the pyramid, there must be some connection between the two places. In the pyramid he solved the Maze of the Gods, and the clue he used was the third puzzle. Because of this, when facing a gate that may come from the same source, it is natural for Mo Yitian to think of those clues.

It seems that this is not a coincidence, and the connection of these clues should lead to something else. As he thought about it, he took out the key and inserted it into the beast's mouth, and the huge stone door opened.
