After walking for more than half an hour, we walked to the mouth of the valley, which was a bamboo forest, Lu Xiu pointed to the entrance of the bamboo forest, and said: "You keep walking forward, and when you come to the end of the bamboo forest, there is a big stone tablet, and there is a mechanism on the stone tablet. There are our people in the pothos barrier, don't you do anything crooked, you know? ”

Naturally, I nodded like garlic, and when I entered the bamboo forest, I immediately pulled out my legs and ran, looking back from time to time, and no one followed. Luckily, they gave me back the flashlight.

The terrain of this bamboo forest is sloping and the ground is covered with soft bamboo leaves, which are easy to fall over, and the bamboo branches are intertwined. People walking in it will be pumped from time to time, especially those wearing Hanfu costumes, wide robes and large sleeves, and their mobility is even more inconvenient, and they are always tripped.

I simply took off my robe and tied it around my waist, which was much easier.

It took about twenty minutes to run out of the bamboo forest, and it was already dark.

At the end of the bamboo forest was a cliff with a very conspicuous stone gate on it, and I tried to push it, but it didn't move.

Looks like I'm going to have to find the big stone tablet that Lu Xiu said.

At the end of the bamboo forest in the dark, there is only the sound of the wind blowing through the bamboo forest, the bamboo leaves fluttering in the dark, and the place where the flashlight sweeps is all dense and upright green bamboo, in addition, how can you see any stone monuments.

But...... The big rock did see one.

The stone was about half a man's height, and there was no trace of artificial polishing, and its shape was completely incompatible with the stone tablet, but I could not find anything else like it at the moment, so I walked over and looked at it twice. At this glance, it was found that on the back of the stone, there was a deeply carved animal with a human face and a bird's body, and the lower body of this animal was impressively close to a woman with a body.

The image of this bird reminds me of a mythical and legendary bird called Jumang, according to legend, Jumang is the god of spring in ancient times, in charge of the germination of plants and trees, according to legend, the place where Jumang stays and flies, even in the middle of winter, it will draw new branches and bloom.

The pattern on this is similar to the legend of the birth of Yumen, could it be that this pattern lock records the story of the ancestors of Yumen?

Is there really a human-faced bird-like god in this world?

I don't think it's very reliable, why do we Chinese claim to be descendants of dragons, but we are not born of dragons?

I saw that the deep carved sentence and the woman, the shape of the interplay is very strange, one arch, the body is very flexible, at first glance, it looks like a Taiji yin and yang fish, and in the middle of the joint part, there is a disc-shaped thing, which is engraved with the heaven and earth and the direction.

When he came, Lu Xiuzhi said casually that there is a mechanism, and it is a very simple mechanism, because this is a door that opens from the inside, and it is aimed at the people in the feather gate, so it is not complicated. I thought it was probably a button or something, but I didn't expect the mechanism in this place to be quite advanced.

There are two layers inside, inside and outside, and I touched it and found that it can be rotated, and it looks like something like a combination password. The outer layer is the ten days of Jia, B, C, Ding, Penhectogen, Xin, Ren Kui, and the inner circle is the north, northeast, east, southeast, southwest, west, northwest eight directions, and the center is a square circle pattern, which seems to have the meaning of a round place.

I pondered for a long time, but I couldn't figure out how this so-called extremely simple mechanism should be opened, and it was turned around at will, and it didn't turn out of a famous place. Subconsciously, I looked at the sealed stone door and suddenly had an idea in my head.

Could it be ...... Is it arranged according to the heavenly stem?

The location of the stone gate happens to be in the east, so I only need to find the heavenly stem corresponding to the east, maybe I can open the mechanism?

Zhou Xuanye has the intention to teach me some skills, so I have memorized these basic things before. In the heavenly stem, A and B are east, and A is positive, and B is biased, so if my guess is correct, then I only need to combine A and the east position of the inner circle to open the mechanism.

This is not difficult, but in a few seconds, with the slight friction sound, I saw that at the moment of alignment, the stone door on the cliff slowly sank into the ground, revealing the black mountain tunnel behind it.

I immediately breathed a sigh of relief, that Lu Xiu didn't lie to me, for those who know how to do it, the difficulty of this mechanism is simply negligible, even if you don't know how to do it, try it one by one, and you can try it out in the end, but it will take time.

This should be equivalent to a very primitive combination lock, and fortunately I have memorized those things before, otherwise I would have to go back and run again.

Immediately, I flashlighted and walked to the open mountain, and the light went in, revealing a hand-polished mountain tunnel, about two meters high and three meters wide, black, and there were wall lamps on the wall, but they were not lit.

I looked, nothing unusual, so I walked in, just went in and walked forward, I heard a clear sound of friction behind me, and when I looked back, it was actually the stone door that had collapsed, and slowly rose up, as if there was some force pushing underground.

In just ten seconds, the entire stone door was completely closed, and in such an environment, people couldn't help but feel as if they were trapped. This feeling is very uncomfortable, probably because humans are social animals.

As soon as I thought that I would be able to join Tan Jian and the others soon, the strange feeling in my heart was suppressed, and I didn't dare to think too much about it, and immediately walked along the tunnel. The interior of the dark mountainside only echoes my footsteps, which is extremely monotonous.

The tunnel is quite long, and I don't feel a trace of wind when I walk through it, and the temperature in the mountain is very low, so I finally got a taste of winter. Because I want to meet quickly, so my speed is actually very fast, but after walking for more than ten minutes, this tunnel has not yet come to an end, which makes people feel a little surprised, after all, in ancient times, tunnels were mined manually, and how much manpower would it cost to dig such a long tunnel in the mountain?

Besides, hasn't Yumen always been thinly populated?

Thinking about it reminds me of the man-made lake before, where everything shows that there was once a large group of people gathered here. Could it be that Yumen was once very prosperous? So now, why is it declining?

With some jumbled thoughts, I finally made my way to the exit.

There are a lot of messy vines growing outside the exit, and the hole is tightly covered, very hidden, and when I get out, there is a downward slope outside, and I almost fell down, but fortunately I caught the surrounding vines in time, so I didn't fall.

By the dim light of the flashlight, I saw that the land below the slope was covered with dense vines, and the rare trees around it were also tightly wrapped by vines.

Except for the light source in my hand, there was no other movement around, it was dark, and I didn't know where Zhou Xuanye and the three of them were. I could only walk down the slope and walk in the opposite direction of the Feather Gate, shouting the names of the three Tan Blades as I went.

There was no voice in my answer, only the song of an unknown strange bird in the night sky, which sounded very permeable, and a layer of mist floated in all directions, and even the mist seemed to turn green in the green scenery.

"Boss!"

"Brother Zhou!"

"Linlin!"

I don't know how long I've been looking for this pothos barrier, this place is very big, and it's too dark, and the surrounding scenery is very single, making it difficult to find a reference, giving people the illusion that they haven't moved all the time, because it looks like it's almost the same in all directions.

Just when I felt a little furious in my heart, a voice suddenly came from behind me: "Su Tiangu." This voice suddenly sounded in the dark, startling me, but the next second I reacted, it was Tan Blade's voice, not to mention how excited it was for a while, and immediately turned around.

Sure enough, Tan Jian was standing under a tree not far behind me.

I was stunned for a moment, because I came from that place just now, and I didn't see any figure at all, at this moment, why did Tan Jian suddenly appear again? When he saw me, he seemed relieved and said, "Sure enough, it's you." ”

I hurriedly trotted over, looked left and right at him, didn't see anyone else, and couldn't help but say: "Boss, where did you come from, why are you alone, Brother Zhou and Linlin?" ”

He didn't answer, but looked at me and said, "Why are you dressed like this?" Have you seen the people of Yumen? ”

I nodded and said, "It's a long story. ”

Tan Jian said: "Then to make a long story short, come with me first." As he spoke, he grabbed my hand, pulled out a flashlight from his waist, turned it on and dragged me to the southwest, and asked me about the situation of Yumen as he walked, so I gave a general account of my experience in the past two days, and reminded: "There must be people from Yumen around here to monitor us, and I pretended to take refuge in them, so they let me out." ”

While talking, we arrived under a big tree, and a tattered tent was set up under the tree, Tan Jian opened the tent, and I looked inside, but saw Zhou Xuanye and Tang Linlin actually sleeping.

What's going on?

Tan Jian said with a heavy face: "Since yesterday, they have been asleep, and they are ......"

"Give me me...... It's my ......" Zhou Xuanye suddenly said vaguely in his dream.

Tan Jian said: "I keep talking in my dreams, and I can't wake up no matter how I scream, so I suspect that this place is a poisonous miasma, and I wanted to take them to retreat first, but I found that the way I came disappeared." ”

My heart sank, the people of Yumen, now that they don't want us to leave, how can they leave a way out? It's just that an avenue disappears for no reason, what kind of means is it?

I tried to call Zhou Xuanye and Tang Linlin, and sure enough, as Tan Jian said, the two of them did not react, as if they were trapped in a dream and couldn't extricate themselves.
