After leaving the Tongtian River, we continued to follow Liu Yuan forward, along the way are some karst landforms, the path is winding, strange rocks, dense vegetation on both sides of the path, many branches have grown, this is not obvious The path is covered tightly, if it is not for Liu Yuan's familiarity with the terrain, in the face of this environment, we may have to come in alone for several days to reach the destination.

Along the way, we followed Liu Yuan's footsteps, he held a firewood knife and constantly cut off the branches around the trees, the surface of the surrounding mountains exposed many caves, the entrance of the cave is five or six meters high, because there are too many caves, we have not seen what the fairy cave looks like, so every time we meet a cave, we will ask Liu Yuan if he has arrived, he was annoyed by our question, so he told us that the cave hall of the fairy cave is as high as dozens of floors of houses, I roughly calculated in my heart, good guys, dozens of floors of houses are so high, it must be nearly 100 meters! The real number of such a tall cave hall is rare, and it is rare to look at the world, I don't know if this Liu Yuan described it is an exaggeration, or is there really a cave in the depths of this mountain?

After hearing Liu Yuan describe the scale of the fairy cave, we all have a rough outline in our hearts, and when we encounter some small caves, we don't ask anymore, just follow him and keep walking forward, the environment in this mountain changes very quickly, the jungle that was still directly exposed to sunlight just now, it rained lightly in a blink of an eye, and the rain was sprinkled on the body, making people feel a little cold.

Liu Yuan, who was walking in the front, suddenly paused, stretched out his hand to feel the size of the rain, and said, "It's bad, it's raining at this time, I'm afraid we won't be able to enter even if we reach the Immortal Cave, so we can only wait outside for dawn." ”

After speaking, Liu Yuan continued to walk forward without looking back, the steps under his feet were much bigger, and the speed was faster, this mountain road was rugged and difficult to walk, coupled with the rain and the road was slippery, we carefully looked at the road under our feet and did not dare to be distracted, as for the scenery on both sides, there was no effort to see it at all.

I walked like this for a whole afternoon, during which Liu Yuan described to us, saying that he had seen the Dragon King in this fairy cave with his own eyes, and the dazzling light in the cave was the treasure of the Dragon King.

Liu Yuan told us more than once, and the Seventh Master and I also pretended to be serious and nodded yes, for the Dragon Lord, the glittering cave, and the treasure thing, we didn't pay attention to it at all, this kind of thing only exists in myths and stories, and the reality definitely does not exist, this Liu Yuan has lived in the mountains for a long time, has shallow cultural knowledge, and has feudal thoughts, and we don't care about him, we just want to arrive at the Immortal Cave as soon as possible and have a look.

Finally, we rushed to the outside of the fairy cave before the sun set, although Liu Yuan had already told us the scale of the fairy cave before, but it was really immersive, I was still shocked by the scene in front of me, the huge cave entrance is 100 meters high, the width is also twenty or thirty meters, the towering trees on both sides of the cave cover the sky, because it is now ten o'clock in the evening, when the bats come out to feed, thousands of bats gather outside the cave, the black pressure is a piece, very scary, but fortunately these are just ordinary bats, not those vampire bats that I encountered before, otherwise at this amount, we would definitely die here.

Liu Yuan waved his hand, signaling that we could set up a tent outside the entrance of the cave to rest, this cave could not be entered at this time, it was easy to encounter danger, and we had to rest all night, and wait until dawn tomorrow to pass.

This time Liu Yuan did not stop us from lighting the bonfire, obviously he also knew that this place was not complete, after eating, according to the old method, except for the sentry man, everyone else rested.

This night I stood at the second post, when Wang Chuyi called me up, the temperature was already very low, although I was very reluctant, but still got out of the warm sleeping bag, after getting dressed, I added some firewood to the fire, and then picked up a flashlight to look around, this deep mountain and dense forest, but the night was very quiet, except for some faint bird calls, there was almost no sound, only the fairy cave was not the same, the wind blew out of the hole, blowing on people, feeling very cold, There was a small river outside the entrance of the cave, which was very clear, and I walked to the river, trying to crouch down and wash my face and relieve my sleepiness.

When my hands touched the river water, I felt that the river water was not as cold as I imagined, the temperature was not much different from other rivers, it stands to reason that the water flowing out of the cave was cooler than the river water outside, and most of them would make people feel cold, but now there is only one explanation for this situation, that is, there is an underground river in this fairy cave! Only in this way can the river maintain such a high temperature without passing through the dark caves.

Just when I held the river water in both hands and was about to wash my face, I suddenly heard the sound of rushing water in the fairy cave, this sound echoed in the cave, like a megaphone, getting louder and louder, I didn't pay much attention to it at first glance, until the river in front of me suddenly increased, almost in an instant, it had already overflowed my ankles, and there was a tendency to continue to rise, I couldn't help but chuckle in my heart, calculate the days, now is the dry season, why does the river water suddenly rise? Could it be that it is really the dragon king's trouble? Looking at the deep hole, I was so distracted that the river had risen to my knees.

At this moment, I suddenly found that not far from the entrance of the cave, there was a huge shadow surging in the river, thinking of the river that surged in an instant, I couldn't help but be surprised, now I can almost be sure that there is indeed an unknown creature in the river water of the fairy cave, and look at the river water that does not exceed my knees at this moment, it proves that the size of this unknown creature is very large! I was so frightened that I quickly retreated for a dozen steps, and before I could stand firm, the river was like a low tide, and it was retracted, and then the whole river became calm again.

I crept closer to the river again, and this time I didn't dare to use a flashlight again, because some of the underwater creatures were mostly phototaxitous and would gather at the sight of bright light.

After I checked the river, I found nothing suspicious, the water was the same as when I first saw it, and the water level became very normal, so I did not dare to stay too long by the river, so I had to retreat again to the tent where we had set up, and after waking up the tiger to take the sentry, and telling him what had just happened, I fell into a deep sleep.

This sleep directly slept until dawn, when the seventh master called me up, Wang Chuyi had already taken a tool and began to measure the water level of the river in the fairy cave, it seems that everyone already knows the scene that happened last night, at this time Liu Yuan is kneeling by the river, and keeps kowtowing in the direction of the fairy cave.

After a while, after Wang Chuyi finished his measurements, he came to my side and said, "According to your description yesterday, the size of the shadow under the water should be very huge, otherwise it will not cause the river to swell. ”

I nodded again and again, Wang Chuyi continued, "There are two conditions for the survival of large creatures, the first is to have enough food, and the second is to have a large enough space, I have just measured, this river, near the shore of the water depth is about six meters, it is estimated that the middle position can reach ten meters, this space is enough, and there are groups of bats in this cave, there are schools of fish in the water, the location of the entrance of the fairy cave, there are many bird nests, and there are also many snakes, which have formed a complete food chain, I speculate, I'm afraid the rumors of the water monster are true, there really is a big guy here. ”

As soon as Wang Chu's words fell, Liu Yuan stood up and walked over and said, "I told you everything, it's the Dragon King!" Wait a minute, don't touch the glowing treasure in the hole, if you anger the dragon lord, it's over. ”

I nodded, indicating that I would not touch it, Liu Yuan walked towards the dense forest with a firewood knife, and soon carried out two thick bamboos, and then began to tie the raft skillfully, during which he didn't say a word, just desperately tied the rope, and waited until the raft was tied, we didn't have any delay, a group of five people, divided into two groups, I and Huzi and Liu Yuan in a group in front. The Seventh Master and Wang Chuyi followed us with a raft.

After entering the fairy cave one after another, I saw that the top of the cave was covered with dense and small pits, and the water droplets dripping from the stalactites on the cave wall made a tinkling sound, I raised my head and observed carefully, only to see that in the gap at the top of the cave, there was the nest of those bats, although there were still some bats hanging upside down on the top of the cave, but most of the bats had already drilled into the gaps.

According to Liu Yuan's description, most of the gaps in the top of this cave are connected to the outside world.

I guess that the wind in the cave blows in through these cracks, and then forms a whirlpool-like air flow inside the cave, this air flow will make a sound when it hits, due to the special geographical environment, the sound of this impact is very peculiar, and it becomes a dragon chant in Liu Yuan's mouth, which is the sound of the dragon lord when he is angry.

The bamboo raft continued to slide forward, the water began to slow down, our strength to support the boat was much smaller, the deeper the cave went, the lower the water level, about five or six hundred meters later, the branches brought into the cave by the flowing water blocked the river, the dead branches piled up together, and formed a high wall, the bamboo raft was no longer passable, we could only walk ashore, along the rock wall gap inside the cave, walk forward, the more we went inside, the narrower the space, but at this time we could already hear the sound of running water, the river was blocked by dead branches, But the water continues to flow forward through cracks in the ground.

In such a huge cavern, everything became very dim, always giving people an eerie feeling, just when we passed through a narrow entrance, suddenly heard a strange noise, as if something popped, fell to the ground, frightened Wang Chuyi hurriedly raised the flashlight towards the place where the sound came from.
