The bats were faster, and in a few moments they all flew away, each with one or two prey on its claws.

Watching the swarm of bats fly out along the cave, Yu Shan's heart moved and followed.

Yu Shan's flight speed was not much slower than that of a bat colony, so before he could be left by a bat colony, Yu Shan discovered the habitat of the bat colony.

Looking at the cave like the knife mountain, Yu Shan couldn't help but feel numb, this is an underground cave, it doesn't seem strange to have any scene, so whether it is the stone knife hanging down from the top of the cave, or the stone sword rising from the ground, Yu Shan doesn't need to be strange.

However, he could always wonder why there were so many stone thorns here, and why these bats chose to breathe here.

The size of the bats is not small, and the danger of crossing this cave is not small, is it to show off their flying skills? Or show how good the ultrasound of bats is?

Flying to the end, Yu Shan found that this cave was actually in the blade cliff he found, and this group of bats lived at the bottom of the cliff, not in the cave.

Looking at the big bats hanging upside down in the crevices of the cliffs, Yu Shan didn't know whether to cry or laugh, the feces of these big bats were all wasted!

If you live in a cave, it's all luminous sand!

And now, it has been washed away by the flowing water, so the bottom of the cliff is clean and refreshing, and there is not even a peculiar smell.

"It's a pity, do you want to find a way to trap these bats in the future? Otherwise, you won't be able to harvest a steady stream of luminous sand. Yu Shan shook his head and flew in the direction of the Heavenly Peak.

There was a lot of delay, and by this time it was already dawn. So Yu Shan didn't continue to look, but returned to the vertical hole at the entrance.

Soul to the core. Yu Shan woke up, took out his mobile phone and looked at it. It was already past five o'clock, and it was already dark outside.

Approaching Qian Xiaohao, Yu Shan directly took the drothel back, this is not Yu Shan's deliberate concealment, who let Qian Xiaohao, this kid sleep like a dead pig?

Retracting the right-handed snail, Yu Shan noticed that the yin qi of the underground Yin River had quieted down, as if it had been locked in the Yin River again.

It's really weird. The yin qi of this yin river erupted, as if there was time, not day.

Yu Shan carefully calculated the time, it seemed that every seven or eight hours, the yin qi in the underground Yin River would gush out along several channels, although the yin qi finally went to the mountain and was not found, but he could also guess some, such as the underground palace on the Heavenly Peak. For example, the eight halls.

Those places should have things supported by yin qi, for example, the cultivation on the side of the Heavenly Peak, and among the eight halls, there must also be places where yin qi is needed.

I won't be able to understand this for a while. Yu Shan simply didn't want to think about it, Qian Xiaohao hadn't woken up yet, but Pang Tong was shouting through the walkie-talkie.

I think Pang Tong is worried about Yu Shan and Qian Xiaohao below. So when it dawned, I immediately started contacting them.

At this time, Qian Xiaohao slept extremely sweetly, and Yu Shan didn't care about him. He picked up the walkie-talkie and communicated with Pang Tong for a few words. Let him wait on it with peace of mind.

Pang Tong is on it, as long as they guard their back road, if the rope is broken, Yu Shan and Qian Xiaohao will be miserable, although they will not be trapped here, but it will always be a trouble.

"Huh? You wake up so early? "When Yu Shan observed the underground Yin River, thinking about the Yin Qi here, why it would erupt regularly, Qian Xiaohao woke up.

"How? Did you sleep well last night? Yu Shan asked with a smile, asking this is just to ask, what is the difference between Qian Xiaohao and a pig.

Unexpectedly, Qian Xiaohao replied seriously: "When I first fell asleep, I woke up several times, dreaming that I was about to slide down the stone, and I grabbed the stone hard, but I couldn't catch it."

After waking up, I found that in fact, my body did not slide down at all, but because I had been sleeping on the highest part of the stone, I was about to fall down from the highest side, and after waking up once, I couldn't sleep even more.

Finally, when the candles are extinguished and the light is all gone, a person will feel that there is a ghost sneaking attack on his head or back in the whole darkness, and he has been scared by ghosts since he was a child, but he didn't expect to be even more scared here.

Later, I thought about it, I could only comfort myself, the ghost came, I fought with him, I died, I was a ghost and fought with him, I had two chances, he only had the chance of a ghost, so I thought about it, I was not afraid, but the ghost should be afraid of me, so I fell asleep, I didn't expect the ghost to be really afraid of the wicked, and I slept extremely comfortably in the second half of the night. ”

Qian Xiaohao stood up and jumped a few times, feeling relaxed, and even the wet feeling on his body didn't seem to be so uncomfortable.

"Refreshed! It's really strange, it's not even five o'clock, and I've slept for five or six hours, how can I rest so well? Can deep sleep really increase sleep quality? Qian Xiaohao stumbled and muttered to himself suspiciously.

Yu Shan's eyebrows tightened, and he thought of something, could it be because of the relationship between those yin qi?

Yu Shan hadn't said anything yet, and at this time Qian Xiaohao also realized something, only to see his face change and say: "No, this feeling is too good, is my skill increased again?" Impossible, right? Sleep here, you can also increase your strength? ”

Yu Shan was really stunned this time, he could think that it should be Qian Xiaohao's spiritual power that has increased, this kid is learning to contemplate thoughts, that is, the soul of exercise, although he can't directly absorb the yin qi to cultivate, but the yin qi that has been transformed by the magic weapon may be able to absorb it.

Yu Shan touched the drothel in his pocket, which was the only explanation he could think of.

Last night's long river of yin qi is definitely not something that ordinary people can bear, and only a Buddhist treasure like a right-handed snail can turn yin qi into peace.

In this way, it makes sense that Qian Xiaohao has gained some benefits.

"Shanzi, do you feel anything abnormal?" Qian Xiaohao looked at Yu Shan and asked suspiciously.

Yu Shan smiled and said, "Is it that the spiritual power has increased?" There is an underground yin river here, so it is appropriate to sleep at night and have nightmares, as for why you can sleep so comfortably in the second half of the night, it must be the result of the blessing of the gods. ”

"Gods? Where is it? You're not going to talk about you, are you? Qian Xiaohao said with a look of disbelief.

Yu Shan smiled and said, "Maybe there are treasures to take care of you, so you can increase your strength even when you fall asleep." ”

"Treasures? You say there's a treasure here? Qian Xiaohao immediately nervously began to look around, like that, with an eager face, as if he had diarrhea and didn't find a toilet.

Yu Shan sneered: "There's no need to be so anxious, right? ”

"How can you not be in a hurry? This is a magic weapon that can be cultivated even when I sleep, if I have such a magic weapon, I just need to sleep well and play well in the future, how much time will it save me? Qian Xiaohao said with a wistful expression.

"No need to daydream, that treasure is mine, and I can't give it to you." Yu Shan directly shattered his illusions.

"Your boy has really made a profit." Qian Xiaohao said with a snicker.

Although Qian Xiaohao's cultivation is not very good, but he has been with Qian Kaiyuan for a long time, and he still has a little knowledge, how can he sleep until dawn in such a place?

There is obviously a reason for this, and the only possibility can only lie in the mountain.

Yu Shan didn't pay attention to Qian Xiaohao's treacherous smile at all, he said directly: "Wealth is not exposed, even if you get benefits, you can't shout indiscriminately." ”

"I know, make a lot of money with a muffled voice!" Qian Xiaohao said with a salivating face.

Although he really wanted to see it, Qian Xiaohao still endured it and didn't ask what kind of magic weapon it was.

Yu Shan thought about it for a while, and didn't mention it, this magic weapon is a trouble, Yu Shan wants to keep it, he has to be careful, so he doesn't plan to take it out, so that Qian Xiaohao is greedy.

"I suspect that the underground here is shrouded by a large formation, so I didn't see any clues before, but now that the Taishan leyline has been triggered, there have been changes here, and this underground Yin River has been exposed.

Today we are trying to drill all the caves to one side, and if we can understand the whole underground, we may be able to deduce what is going on. Yu Shan directly changed the topic.

"Okay, surveying and mapping is my forte, you have to say earlier, I use a compass to record the terrain and direction here, then it will be easier." Qian Xiaohao immediately said.

Yu Shan said: "It's not too late, let's have breakfast first, and after breakfast, we will start to act." ”

Boil water and eat compressed biscuits, Qian Xiaohao and Pang Tong heard that they were going to explore, and they didn't know how much time it would take, so in order to deal with the accident, Qian Xiaohao and the most food they bought was compressed biscuits.

Luckily, the two of them weren't planning to stay here for long, so they were going to eat some.

After breakfast, put on my gear and walk along the upper reaches of the underground river, to the end, to climb into the pipe cave I found yesterday, and into the most beautiful large space inside.

Although Yu Shan didn't come over to take a look last night, Yu Shan knew that this place was all a place for the Heavenly Ghost Sect to cultivate.

Shoot with your mobile phone all the way, in this place, Yu Shan and Qian Xiaohao found a lot of beautiful stalactites, Pang Tong didn't come down, how can they take pictures of it, let Pang Tong take a look.

There are not as many stalactites here as in the eight halls, but the stalactites here are of better texture.

Even Yu Shan saw a white and transparent stalactite, which was like a piece of jade, with a crystalline surface that sparkled in the light of the headlamp.

This stalactite is about ten centimeters thick and more than two feet high, and there are other things such as stone grapes.

After checking all the way, I finally had to find a main road, which was the innermost part of a cave hall, where there was a very steep uphill, and after two people climbed to the top, it seemed that the cave ended here, and no other passage was found.

But where did the traces of the torch burn come from? (To be continued.) )
