Yunwen and I didn't dare to stay. Sanfu also squatted sensibly. We got on the horse and hurriedly rode down the mountain. We galloped all the way, and our speed was already fast. However, the stone walls and mountain walls were still rising. I didn't know if we had touched some mechanism.

The ascent was very fast. Sanfu ran at first, and he could jump over some obstacles. But the more he ran, the higher the walls became. Even though Sanfu was tall and could jump very high, he could not pass the obstacles by simply jumping over them as before. In a blink of an eye, the stone walls had reached a height of four or five meters, as high as two floors. No matter how high Sanfu could jump, he was not a grasshopper, and he certainly could not jump over a height that was twice his shoulder height.

Gradually, we could only run along the aisles in the middle of these stone walls and mountain cliffs, and run in the narrow passages in them, which basically trapped us in a maze. There were only two roads in the West Zhou Dynasty, with occasional forks. If we made a wrong judgment, we would enter a dead end, or we would have to go back. In short, these stone walls were piled high, blocking out light and wind, and could only confuse people's five senses. They didn't know what to do, and they were like headless flies, wandering around everywhere.

Sanfu's physical strength and endurance must be good. He has been running in it for half an hour and can still hold on. But Yunwen and I also know that this is not a solution. Before we can think of a suitable way, we should not waste our physical strength easily. After all, the whole mountain top has become a maze. We don't know how many times we have gone around. If we continue blindly, we will be trapped to death.

Yunwen stopped the horse and we both got off and looked at the stone wall that suddenly appeared abruptly. It was tall and towering, and we felt at a loss. It was because we were in this mountain. Now we were in this maze. We were really like people in a game, like frogs in a well. We could only see a corner. We looked around and saw endless stone walls all around us. Most of them were similar. The light was dim and it was very difficult to see any major differences.

"We didn't touch anything just now, how come such a pile of rock walls rose up and trapped us inside?" I asked.

"The Root of Heaven and Earth, I think it's because of the Root of Heaven and Earth. You were fighting with it just now, and the Golden Que Sword destroyed a small part of its connecting rhizomes. These Roots of Heaven and Earth spread one after another underground, and are controlled by a mother body. If you destroy one part of it, the entire mother body will launch a malicious attack against you. This maze might have been pushed up from the ground, with the purpose of trapping and killing the invaders inside." Yunwen said.

"Is the Xuanpin Gate the root of heaven and earth? Since it is the Xuanpin Gate, it should be the same as the Tao. At least it should be a little tolerant. It was obviously the one who attacked you first, and now we are fighting back a little, why is it still angry?" I expressed my confusion.

"It's just called the Root of Heaven and Earth, and it has nothing to do with the Great Dao. This Root of Heaven and Earth is an ancient evil creature that is stationed underground and grows by consuming the spiritual energy of the earth. It is extremely poisonous and highly aggressive, and it has a vengeful nature that will punish anyone who offends it, no matter how far away they are. I'm afraid that's why we are deeply trapped in it now." Yunwen said.

"It should be called the Unreasonable Root. Giving it a name like the Root of Heaven and Earth is really disrespectful to the ancient saints. But how could it create a maze directly? Besides, why didn't we see it when we came here in winter and spring before?" I asked.

"I have seen it before. Do you remember where you saved me?" Yunwen asked.

I thought back. When I first arrived at the mountain, the nine-tailed white fox sent me to the top of the mountain. The area we were in was surrounded by purple mist, which was a kind of poisonous miasma. After that, when I saw Yunwen, I didn't spend much time to judge the surrounding environment and was in a hurry to save her. Now I think about it, she should be within the boundary I drew before, that is, within the poisonous miasma area in the mountain.

Of course, I didn't feel poisoned and unconscious in this area this time, also because that part of the root of heaven and earth was destroyed by me just now, the fog dispersed a lot, and also I covered my mouth and nose in time in the area with higher concentration. That thing needs a long time of inhalation to cause local nerve anesthesia, accompanied by slight fever and swelling of the head, and it will take a long time to work and cause coma. The situation was not that serious when I rescued Yunwen just now.

But now I see that there is more and more purple mist in this maze, but for some reason I don’t feel that the ancient man with a hot head is here anymore.

"Remember, the place where you were rescued seemed to be within the poisonous miasma area." I said.

"The purple poisonous fog is the poisonous gas of the Root of Heaven and Earth, so we have seen it at that time, but I didn't explain it to you clearly. As for why such a maze suddenly appeared, I don't know. But in the Tiancan scroll, I remember the description of the Root of Heaven and Earth is, 'The Root of Heaven and Earth is good at trapping things. When the things are exhausted and exhausted, and there is nothing they can do, it will swallow them alive to replenish its mother root.' It means that it is good at being trapped to death by living things, and then swallowing them alive. Therefore, it may have built such a maze specifically to trap things." Yunwen said.

I went to the stone wall and touched it. Indeed, the piled earth and stones on the stone wall were all in a disorderly manner. They had not been artificially excavated, but were constructed in a special way. I gently touched the joints between the earth and stones on top. In addition to a lot of rotten things, there were also a lot of sticky substances. These sticky substances had solidified and felt very hard.

It is said that birds sometimes use their saliva as adhesive when building nests. For example, swiftlets and common swifts are good at this. Moreover, many trees secrete some sticky gum. The roots of heaven and earth may not have gum or saliva, but it is thought that they also use some kind of highly sticky adhesive to make these soil and rocks stick together like the principle of nesting. They are particularly strong, comparable to cement and steel bars, and can be glued together and cannot be easily kicked apart.

"It's really cruel and ruthless! By the way, since it also appears in the Tiancanjuan, could it be one of the eight treasures of Taiqiong Cave?" I asked.

Yunwen shook her head and said, "Not really, but its magical power is not inferior to that of a treasure, so we all have to be careful."

I nodded.

It seems that our plan to escape is impossible. After all, this maze is strange. No matter how we run up, down, left, or right, we will end up back in this place. It may really have the ability to trap people to death. Just now, I didn’t care too much in order to save Yunwen. The swing of the Golden Que Sword exhausted all my energy. It was only by licking it a few times by Sanfu that I recovered some strength.

I have also thought about using the powerful dragon soul scales on Sanfu's body to store spiritual energy, just like I did that day when I dealt with the black knight monster. I could ride on it and use the Golden Que Sword to destroy its mechanisms at will. But now Sanfu's dragon scales haven't grown back yet. If I'm not sure what to do, I'm afraid it will waste its vitality and be useless. Besides, it has to agree to borrow it. When Yunwen is not in danger, I can't use it even if I want to. If it could be used, the Golden Que Sword should have reacted when I was riding the horse just now and started to shine again.

I had no choice but to continue leading the team forward to see if there were any other clues. Unfortunately, after walking around and going forward, there was only one road. We should have gone directly outside, but we found that we were circled back. We had made enough marks along the way, so we decided to walk it again, trying to avoid the marks we had made before and not feeling that we had taken a detour. Unfortunately, after walking for a long time, we ended up back at the starting point.

We were all dizzy and sweating from walking. We were constantly walking in this endless wall of earth and rocks and the purple mist was rising. We were exhausted.

"We have walked all the roads around here, some are repeated and some are not, and there is no sense of turning. Why can't we get out?" I couldn't help but worry.

"In fact, even the roads in the civilized world are mostly not straight, but have some curves. This maze is the same. Its curves are subtle and easy for our subconscious mind to think that they are unimportant and not pay attention to them. By the time we react, we are back to the starting point." Yunwen said.

However, at this moment, I suddenly heard a subtle sound, a kind of gurgling sound. I immediately smiled and said to her, "You just said that it was the mother body that made these stone walls rise. Could it be that it adjusted the curvature of the stone walls to make them move, thereby deceiving our subconscious and misleading us to come back?"
