I was stunned, how did the Seventh Master of the Heart Dao know that I had entered that secret passage: "Yes, I just came out of that secret passage." ”

"That's right." The Seventh Master explained: "Outside, there are four bright mirror-like cliffs by the lake, and the four secret passages are the inside of the mountain that leads to the four cliffs. In addition to the secret passage in the cave we entered one after another, there are two other tombs that lead to one ice and one fire, and the remaining one leads here. ”

"How do you know?" After being scolded by the man in black, my good impression of the Seventh Master and the Budai monk suddenly disappeared, and the original "you" was replaced by "you": "Have you entered those secret passages?" ”

The Seventh Master shook his head: "No, on the way in, I can roughly guess the specific structure of this Chengling hanging coffin." ”

I opened my mouth and asked, "Microclimate?" ”

"Yes!" The Seventh Master nodded and said, "The entire Chengling Hanging Coffin is in a wonderful microclimate. I don't know how many years the spring rainstorm will make this microclimate completely displayed, Yuwentai is based on this strange climate, transformed into a tomb hanging coffin. According to my guess, during the rainstorm in the beginning of spring, the canyon outside will be flooded by rain because of the scarcity of vegetation; In the interior of the cave, that is, in the first layer of the cliff, there are three lakes, except for the first lake that directly receives the rainwater pouring in from the outside, the other two lakes are formed because of the topography and geology, one up and one on the other, one fire and one ice. ”

The old clam interjected and asked, "Why doesn't this happen during the summer rainstorm?" ”

The seventh master grinned: "It's very simple, first, there are many vegetation in summer, and the rain will not collect so much; Second, because of the lake in the mountains, the phenomenon of fire and ice melting only occurs in the beginning of spring. Of course, this is just my guess, but if you follow this route, it shouldn't be too much of a guess. After the lake of fire melted into the lake, the rainwater poured in from the outside and the water from the normal pool, and through the huge tank built by Yuwentai, it merged into the lake in the second cliff wall. It's the lake out there where the water level is rising. ”

"It's a trick!" The old clam sighed: "Yuwentai is really smart, there are so many hanging tombs dug on the cliffs on all sides outside, if someone comes in and believes it, looking for it outside for a few days, it is almost equivalent to waiting for death!" ”

"That's right." The Seventh Master continued: "In fact, most people will not find the real Chengling hanging coffin in the third layer of cliffs. But Yu Wentai thinks farther than us, even if we come in now, if we don't get out as soon as possible, we will still wait here to die. ”

Why is that? I frowned, after the seventh master said this, I quickly built the entire Chengling hanging coffin in my mind, at this time I heard that I had to go out as soon as possible, and I went through it in my mind, and suddenly remembered something: "Seventh master, you mean that in this hanging coffin, going out from the top of the cliff is a dead end, and we can only go back from the two layers of cliffs that pass through the outside according to the original way, but because of the microclimate, the fire lake with the only exit will slowly refreeze into a frozen lake after the rain disappears?" ”

"That's right!" The seventh master smiled: "What Xiao Gu said is right. The two lakes, one fire and one ice, are not opposite each other all the time, but most of the time, they are ice lakes. Only at certain times does the lower glacial lake begin to melt due to the rising temperature underground, and it quickly becomes boiling water, taking advantage of the high temperature to quickly melt the glacial lake directly above it. And after the rain recedes, it will quickly recover into a glacial lake in a short time, and once it arrives, it is impossible for us to smash through such thick ice rocks to get out, so we are also waiting for death. ”

"And what about the only way out?" I asked immediately.

"The only way out is to go back to the lake outside from the waterhole where you came in, or the cliff where we came in, and follow the secret passage back to the cave before the rain recedes completely."

"So, at what time will the rain reced?" Liang Ruoyi asked.

The Seventh Master groaned and looked at the cloth bag monk.

The old monk recited a Buddha name: "If you count according to time, one end and one tail, one convergence and one retreat." A total of five days, with rainwater beginning to collect on the first day and pouring into the lake on the second day; Then, on the fourth day the rain began to recede, and on the fifth day it was completely restored, so that the water level had already begun to drop, and the remaining time should be about three hours. ”

Three hours? In other words, six hours is quite a lot of time. I nodded, but when I turned my head to look at the stone pillar that pierced the sky, my heart suddenly cooled! Just talking about these stone pillars that are hundreds of meters high, climbing up is a problem!

"Time is running out, let's go up!" The seventh master said in a deep voice.

I hurriedly waved my hand: "That, Seventh Master, I'll wait below, okay?" That's too high! ”

The seventh master shook his head without hesitation: "No, Xiao Gu, let's not say that we need you, just say that we will probably walk on it when we leave, you stay below, we can't have time to come back to save you!" ”

But ...... "I don't have a better reason for a while, I can't stay down there and die."

"It's okay, we're in two groups and we're pulling with ropes." Liang Ruoyi proposed.

The seventh master responded: "It's okay, then, Miss Liang, you take Xiao Gu with you, let's work in groups of three." This stone pillar looks like it should be 300 meters high, because it is a spiraling hanging stone steps, it is best for each of us to tie two ropes around our waists, one for others and one for walking on the stone steps above to ensure safety! ”

In the dark, everyone nodded, tied the wristband of the flashlight, and tied it to the wrist, because they were afraid of shaking their partner's eyes in the process of spiraling, they all adjusted to near weak light, tied the rope, and finally checked that there was no problem, the old clam was in the front, followed by the seventh master, the cloth bag monk, me and Liang Ruoyi, and stepped on the hanging stone steps.

More than a thousand years have passed, and the stone steps under your feet are still sturdy, and you don't shake when you step on them. The height difference between each of the two stone steps is about one foot, and the difference between the front and back is about one foot, so spiraling around the huge stone pillar with a diameter of about two zhang, as if dancing in mid-air, but the atmosphere is too different, after going up about five meters high, I shine the flashlight downward, and my legs are weak, and I almost fell down!

"Don't look down!" Liang Ruoyi said.

I was so frightened that I stopped, grasping the rope with one hand and the stone steps in front of me with the other, and my voice was full of tears: "God, I was wrong, what is this to do!" I can't stand it if it's more than five meters! There are more than 200 meters to ......"

"If you don't look down, there's nothing!" The old clam shouted on it: "Boy, I tell you, the most terrible thing about this road is not the difference in height between up and down, but the ......"

Before the old clam finished speaking, the seventh master directly interrupted: "Xiao Gu, listen to Miss Liang, if you don't look down, there will be nothing." ”

I nodded, answered, swung my legs, which were already a little numb, and continued to walk upward.

In the endless darkness, five weak flashlight lights, like five jumping elves, walked slowly upward around the stone pillar. I finally got over the urge to look down and walked cautiously upwards step by step.

I don't know how long I walked, but I finally understood what Lao Clam meant when he said that "the most terrible thing is not the height difference between up and down"!

People repeat the same actions in the same environment for a long time, and they will produce a wonderful psychology, or a kind of treacherous illusion. I climbed up in the darkness at such an almost uniform pace, that at last I could not help but look around with my flashlight—it was all darkness, and downward, it was darkness; upward, is darkness; There is darkness on one side of my body, and there is a stone pillar on the other, and the darkness on this side and the stone pillar on the other side are still transforming into each other as the angle of my body changes!

I felt a sense of weightlessness all of a sudden. It's like I'm in an endless universe, walking with my feet that never ends, and there is always darkness in front of me......

Coupled with the fact that the road is spiraling, after I looked around, I suddenly felt that my head was dizzy, and my body in the endless darkness was also fluttering, and I instinctively closed my eyes.
