Qin Yujie said: "That's right, Brother Feng, this is the Inner Dan of the Blood-Eyed Bull Demon."

"It's a ball of Nedan, a broken stone, right?" : I stared at Qin Yujie's hand, at the red one, at the round object with a texture like a stone.

"Brother Feng, do you understand? , this is Neidan, and it's not a stone, if you have time, you should really learn this knowledge": Qin Yujie put on an expression that you are too stupid.

"I know how to rob tombs, how to understand what is from that dynasty, how many generations of our family have been doing this, these heavenly treasures, I know that there are really very few, and I am ashamed to be ashamed of my third uncle's hard work": I also said with an embarrassed smile.

Qin Yujie didn't look at me either, put away the blood-eyed bull demon's Neidan, stood up, and it happened that Lei Zi and Lone Wolf also checked the dead monsters on the ground, and found that there were no living ones, so they joined us together.

"Master, I'm afraid there are more than these monsters in this resentful dragon land, there should be more, I don't know what it is, you should be careful": the spirit bones that easily didn't open their mouths actually reminded us loudly.

"Well, I know, Spirit Bone, thank you for the reminder": I still sincerely thank Spirit Bone, since the last incident with the white-skinned old fox, our relationship has been relatively harmonious.

"Nothing is still alive, Xiaolinzi, what should we do, did you find anything when you observed the terrain from the outside a few days ago?" : Lei Zi held Cao Hao's sword, stood beside me and asked.

"Observing from the outside, there is nothing to find, it can only show that this place will not be peaceful, the dragon veins have been cut off, and there is resentment, if there are dead things inside, most of them will become powerful evil things, if we enter here, we must be careful"

"Meihua, you take Hu Dazhuang, go ahead first": I called Meihua and asked her to take the fire zombie and explore the way for us first.

I took back the red and yellow paper figures, and recalled the cyan paper figures, and when the blue paper figures fell back into my hands, I paused and slowly put them into my arms.

Everyone followed the plum blossoms and the fire zombies, and slowly walked inside, this valley was very large, winding and rugged mountains, a full number of kilometers, but when we walked slowly for about a kilometer, we didn't even find any danger.

This makes us all wonder a little, why are there so many terrifying monsters at the mouth of the valley, but not a single monster can be seen at such a distance inside? Could it be that these monsters are all artificially arranged there?

But in the valley, we saw the bones of some small animals, although not many, which made me wonder that the bones of these animals were relatively complete.

There was no sign of being attacked by large monsters, but it was strange that so many animals had died, and along the way, a few of us found about 100 animal bones.

The road in the valley is also very difficult to walk, we walked about a kilometer, and it took more than half an hour, along the way, we are very careful, always on guard, there will be some dangers.

A few of us, about a kilometer forward, I saw a black hole in the distance, looking at the distance, it was still a little far away.

At this time, Qin Yujie also seemed to have discovered that in this team at the moment, the two of us have the best eyesight.

"Brother Feng, there seems to be a hole in the distance, under the mountain in the distance" After finishing speaking, he pointed to a direction in the distance, and the cave was in the northwest direction.

"Well, I saw it too, how do I look at it, there shouldn't be such a big cave in this Kunlun Mountain, I suspect that there are unspeakable secrets in it, and even where did these monsters come from"

Lei Zihe took out the telescope, put it in front of his eyes to look at the dark cave in the distance, observed for a while, put down the telescope and said: "Xiaolinzi, that cave, at least one kilometer away from our current location, that cave should be very large, the location of the cave entrance, there seem to be two huge long stones"

I looked at Lei Zi and asked, "Long stones?" How big is this long stone, can you analyze it from what you just observed and how long it is at a distance? ”

"It's at least more than ten meters long, and the two boulders are aligned, that is, this may be artificially constructed, otherwise how can the two boulders be very flat, and the distance between the left and right is aligned?"

The four of us looked at each other for a moment, and we all began to guess in our hearts, what kind of place is this?

I've been in Kunlun Mountain for a few days, but I haven't heard a little from my father, not even a little clue, but I have encountered a lot of monsters and strange things.

After discovering this cave, we sped up a lot, and it took less than 20 minutes to reach the entrance of this dark cave, and when we got closer, we found that this cave was so big, it was more than 20 meters high.

It's pitch black, and I don't know what's inside, and there's a trace of light inside, and there's no light inside, and the boulders on both sides look like snakes, I'm afraid these two boulders, each of which costs dozens of tons, right?

"Everyone be careful, there is no light here, and I don't know what the situation is inside, Leizi, lone wolf, you bring night vision devices, Yu Jie and I don't need it, we can also see it in the dark"

"But there's a lot of space in here, and the distance I can see is very limited, I don't know how far Yu Jie can see?"

"I'm pretty much the same, what I see is very limited, and the role is not very big, if necessary, I still have to use a flashlight, so bring the flashlight."

I took out the wolf's eye flashlight from my eight-treasure ruyi bag, Qin Yujie also took one, and when Lei Zi and Lone Wolf were distributing equipment, both of them brought flashlights.

After we entered this pitch-black cave, my gaze emitted a faint red light, and Qin Yujie was similar, with a hint of light in both eyes.

Lei Zi and Lone Wolf turned on the night vision device, a night vision device with infrared imaging, at present, this equipment is still very high-end, and it is often used by some mercenaries and special forces personnel.

What surprised me the most was the spirit bone, she was walking on my right side, and the reason for my surprise was that her eyes, like two purple flashlights, shone more than twenty meters away.

In this cave, in the huge empty space, it seemed unusually silent, only the footsteps of a few of us echoed in everyone's ears.

The dark space ahead, as if there was no end, had been stretching inside, and after walking for a few minutes, I heard a strange noise.
