Walking in this dark and endless place of evil, every step must be taken carefully, and every poplar tree is densely covered with the outline of human faces, these faces have not yet broken free from the confinement of the poplar tree, and they are all round with empty eyes, wide and twisted mouths, staring at us.

Luckily, they didn't break free like the faces just now, otherwise we would have been torn to the point that there was no scum left. If you think about it, if these faces were all stripped from the dead and then pasted on, then this place is probably hiding thousands of wandering souls, and these unseen souls are likely to be hovering around us.

If you open your mind a little bigger, you can also think that every poplar tree here is a living person, and they may have been cursed by some terrible curse, so they are forever imprisoned in this dark place.

"Why did Xiao Qing plant so many poplar trees in his tomb?" Alan Lin looked at the trees in front of her and asked suddenly.

"Maybe it's to green the environment and improve the ecology." Zheng Tian replied casually while fiddling with his DV.

"You mean he wants to build an ecological civilization and take the path of sustainable development?" I said with a smile.

"That's what I'll say, but the scene in front of me is really magical, and you can't even use a green screen to shoot a movie here." Zheng Tian used DV to take a panoramic shot of these poplar trees with human faces.

"I guess it's some kind of ritual, you see these poplar trees arranged so neatly, like guardian believers, and the coffin in front of the tree, it makes this place look like the road to the altar.

"Speaking of this coffin, I have long wanted to ask, why are they all placed in front of the big tree, is this your Chinese tree burial custom?" John asked.

I shook my head and was just about to speak, when I suddenly heard a sound of prying things behind me, and turned my head to look, it turned out that it was the fat bear who started the idea of placing the coffin in front of the tree. I hurriedly drank him: "Stop! Can't open the coffin! ”

Fat Bear said impatiently: "Fat Master, I'll do a simple inspection, and it won't be delayed for too long." ”

I walked to his side, pressed the crowbar in his hand and said, "You are still an old man, why have you forgotten even the most basic things, Uncle Dao once told me, 'Arrange the coffin in front of the tree, put the Gu for the soul', your coffin will only cause unwarranted right and wrong." ”

John was very interested in what I said, and asked me what I meant, but I didn't know what it meant, but I knew that there must be something bad in this coffin, and after a few perfunctory words to him, he pointed to the faces of the people on the trees and scared the fat bear and said: "Look at these faces, they may not want to open the museum like you when they were alive, and it turned out to be what it is now." ”

"You dead fat man don't want to die yourself, don't pit us all together!" Zheng Tian was a little frightened when he heard this, and hurriedly accused Fat Xiongdao.

The fat bear was discouraged by what I said, and after muttering a few words, he let go of the crowbar, and after a few minutes of walking on, Elan Lin suddenly shouted at us in surprise: "Look! There are markers on this tree! ”

We hurriedly gathered to the tree she was pointing to, and found that there was indeed a V-shaped mark in the gap between the faces, exactly like the one we had seen before, which should have been left by Gan Feng and them.

"They're still alive." Alan Lin stared at the mark and whispered.

Professor Wu also sighed: "And they have always believed that we will come." ”

I muttered a little in my heart, after all, anything can happen in this kind of place, and Gan Feng and they really have to say whether they are dead or alive now.

After a quarter of an hour of walking through the poplar forest, we finally came to the end of a large body of water, and it was hard for me to imagine such a large underground river beneath the desert if I hadn't seen it with my own eyes. If I had to make an analogy, I feel that this body of water is no less than the size of Xuanwu Lake.

At this time, the entire underground world has changed from a small opening at the beginning to a big world now, and the flashlight hit the rock wall overhead, and the light quickly disappeared, and there was no end in sight. It seems that we have been going diagonally downwards before, otherwise we would not have come to such a huge underground world.

"Do you smell anything strange?" Zheng Tian suddenly asked with a few snorts.

Due to the fierce battle before, my mouth and nose were already full of blood, so I was not very sensitive to some smells from the outside world...... How to put it, it's a bit like the taste of sulfuric acid.

John saw the water source, very excited, probably because of the habit of cleanliness and the eagerness to clean the blood stains on his body, regardless of what Zheng Tian said, he hurriedly ran over to get a handful of water to wash his face, suddenly, a message flashed through my mind, I immediately ran forward and grabbed John: "Don't wash!" ”

But it was too late for me to catch it, and John had already put one hand into the water, and the next second I heard his heart-rending wail of pain.

I hurriedly dragged him back, and found that the upper half of his two fingers that were stained with water were corroded in an instant, and the blood kept bubbling out, and the white bones were shocking to look at.

"It's ...... It's stinging! Zheng Tian called out suddenly.

"yes, we meet again." As I spoke, I took the gauze handed over by Ai Lanlin and bandaged the reckless fellow first, and then told the rest of the group about what happened to us in Zanglong Mountain.

Although the fat bear also went to Zanglong Mountain, he later separated from us and went out on a different route, so he didn't experience the stinging pool, but this man-eating sting left an indelible impression on me.

"In the "Secret Book of Heavenly Works", it is said that the stinging water originated in the Western Regions, and it is likely to be the one in front of us." I can't believe that what lives only in legends and documents has found its roots.

"But I'm more concerned about how we're going to get over now." Elanlyn looked at the vast water in front of her and said anxiously.

"In the water, the feathers don't float, and there is no way to pass at all!" I shook my head regretfully.

"I'm sure there's a way." Professor Wu said firmly.

"Why are you so sure?" I was a little puzzled by Professor Wu's fascinated confidence.

"There is only one way to come, and when we get here, Ganfeng and they are gone, indicating that they must have successfully crossed the river." Professor Wu said.

Indeed, if Gan Feng and the others weren't stupid enough to strip naked and jump into the river in an attempt to swim over and then be instantly melted into powder, they should have found a way to cross the river safely.

"Chengzi, do you remember how your Uncle Dao and Wei Yin crossed the stinging waters in the ancient tomb of Zanglong Mountain?" Zheng Tian asked.

I thought back for a moment and said, "It was as if there was an uncorroded ship that floated up in front of them and took them away." ”
