It was almost noon, and the sun was shining hotly on our heads, so Hu Yinman and I carefully bypassed the huge red cage ghost fungus, and walked at the bottom of the sinkhole close to the mountain wall, with all kinds of vegetation in between, and the verdant bamboo forest also blocked some of the light for us.

"It's weird here. It stands to reason that all the plants in the sinkhole will be very "slim" because they compete for the sun and desperately grow upward. But it's different here, except for those red cage ghost mushrooms that have just grown, everything is growing in a decent way. Hu Yinman whispered.

I listened to her and took a general look at the plants, but they were exactly as she had described. This is a shrub layer dominated by small patches of palm bamboo. There are many herbs with ancient origins, and Hu Yinman later told me that these are mainly precious varieties such as narrow-leaved nest fern, cold fern, and dark green short-intestine fern, and almost all of them have developed into shade fleshy herbaceous forms.

However, it is not only on the cliffs around these sinkholes, there are coniferous broad-leaved evergreen and deciduous mixed forest plant communities, including trees and other shrubs and herbaceous plants represented by palm-leaved trees, short-leaved yellow cedars, Fujian cypress, etc.

However, none of them are stunted small vegetation that is no taller than a single one. We climbed over a boulder, and I said to her, "There are steep rock walls around the sinkhole, how do you think these things grow?" ”

Hu Yinman gave me a blank look, as if she thought that the question I was asking was a bit silly, but she still explained to me: "As long as there is periodic rainfall, or there are other plants symbiotic in the surrounding area, as well as high air humidity, relatively shady environment, etc., it is suitable for the growth of some plants." ”

I nodded, and by this time I had come to a concave in the rock formation, which was blocked by a large mass of tree roots, filled with plants and dirt, and the initial torrential rain seemed to have no effect on these tenacious plants. It seems that it has been here for a long time. Hu Yinman and I switched places, crawling along the rock fragments towards the edge of the underground river.

Halfway through, I stood on a high place and looked down at the concave surface in front of me, and I actually felt that this place felt a little familiar.

After a while, Hu Yinman and I walked to the entrance of the underground crack, and the water flowed rapidly below, bringing up white waves, and a cold wind in the river. The whole underground river is like an inverted trumpet, and the wide cave roof above the narrow river channel shines like a strange deep night sky with torches, and the countless stone curtains glow with sparkling phosphorescence, and resemble the stars in the night sky.

"There's a crack there that seems to be separate." Hu Yinman said to me suddenly.

"Where?" I howled at the sound of the water.

"You see there's a swarthy fork in the river." Hu Yinman pointed with his hand. I looked along my hand, and sure enough, a few steps away from the underground river, there was a black hole that could hold three or four people, and there was nothing to see inside, and it was pitch black.

"Let's take a look?" I said to her, with a bit of provocation, in fact, I was joking with her, I hope she is here to wait for me.

"Just go." She raised her head and pouted and looked at me, "I have climbed through various caves by the Qingshui River in junior high school, and this thing is not a piece of cake." ”

"Okay, let's feed it." I just wanted to propose a plan to climb over, but before I finished speaking, I saw Hu Yinman with one foot on the round stone, and jumped over with one hand holding the stone pillar on the river, and there were a few upright stone pillars in the underground river, these stone pillars were basically stone stalactites formed over hundreds of millions of years, they hung upside down from above, and finally reached such a length after the accumulation of time.

"Okay." When I didn't say it, I was embarrassed and took care of myself as I gave myself a chance to laugh at myself. This girl is too tough, just do it, this surname. After thinking about it, I realized that I had no words to lament her, because she had jumped to the opposite side.

"You're so slow! How can I not pay it back. She grinned and stood in the crack of the underground river and shook her hand at me.

"Okay, okay, miss, don't walk around. Am I still going to carry a torch? ”

"Then you threw it over?" Hu Yinman's eyes narrowed into an arc and a half moon, it seems that this Nizi wants to run away with the fire. But I couldn't help it, so I waved at her to stand away, and I threw the torch over.

I looked at the perimeter of the dark river, found the position where Hu Yinman stood before, and jumped cautiously, this jump, I immediately felt that the air in this cave was extremely cold, the cold wind blew across the water, and it was surprisingly big, I held the stone pillar with one hand and tightened my clothes, and subconsciously said: "This is too cold!" ”

"What do you think? The underground river is like that, but the wind here is relatively small, and the bigger ones can blow you away. Besides, because there is no direct sunlight and it is far from the surface, can it not be cold? Hu Yinman lay on his stomach at the mouth of the crack and looked at me with half of his head smiling.

"Hey, you can light the torch for me." I'm a little worried about her running away right now.

"I know, I know." She and he shone it at me with a torch, and I looked back to see that the river was winding, sometimes open, sometimes narrow, and it was really chilling to look at it. I jumped over a few stones, and finally landed in the crack of this dark river, only to find that Hu Yinman didn't know where to run?

"You really left me." I shouted, "There's a ghost in there." "I just wanted to scare her, but now I'm panicking, this voice is obviously encountering something?" What's wrong? What's going on? I shouted as I walked through the cave in the dark.

"Come here, where are you?" Hu Yinman screamed.

A little fire lit up not far away, and I hurried over. In front of her was a corpse, lying on the ground, probably tripping her up! No wonder she reacted in this way, I ran over and helped her up, but when I saw the corpse on the ground, I was suddenly stunned, the corpse was actually dressed in modern clothes, and the corpse was not completely shriveled, obviously just dead. But now there is a slight smell of corpses.

"Don't be afraid, don't be afraid of the dead." I hugged Hu Yinman behind me, and then pinched his nose and looked at the corpse carefully, he was back up, face down, so I couldn't see her face clearly, but from her coiled hair, it could be seen that it should be a woman, I walked up and kicked the corpse, and found that the corpse was already stiff, it seems that the time of death was more than 30 hours, so it was the last day or two? I resisted the stench and turned the body over, and a face I didn't expect came to my eyes.

"Why? Why her? "Countless voices in my heart shouted." What's going on? Aren't they gone? Why did you find this place before me? What are they looking for? ”

"What's wrong?" Hu Yinman seemed to see what was on my mind: "Do you know this woman?" Is it your girlfriend? ”

I ignored her, it was so sudden that a few days ago she was my captive, she told me some things about Pangu, and even threatened me with her cold eyes, but now she actually died here? Why? I suddenly felt that this thing was not ordinary, so the things around me were like a labyrinth, and the people who entered the labyrinth either accompanied me to die in it forever, or a few people were crazy to go here, and they could not escape the fate of death.

"Let's go, I don't know her." I couldn't help but take Hu Yinman's hand and walk towards the depths of the crack, I wanted to take a look, I desperately wanted to see what was in the depths that would attract them? And what made her die here?

Now that the sky is completely dark, Hu Yinman and I are holding torches and carefully exploring the crack, and the firelight reflects the walls in the crack red. But I don't know if it's insects or the wind blowing the branches, and there is always a sound in my ears. This rustling sound stings my eardrums all the time.
