"Ghost blowing the lamp?" Hearing this, my heart suddenly shocked: "Didn't you say before that the ghost blowing the lamp is actually a lack of oxygen?" ”

Beard nodded: "It's hypoxia, I'm talking about hypoxia, damn, you're right, the water pressure squeezes out the air, and we're going to be hypoxic soon." Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ”

Wrong! I suddenly realized that although the lighter didn't hit, I didn't feel suffocated. So why can't the firebolt hit? As soon as I said what I thought, the beard rolled his eyes and said, "Is it the wind?" As he spoke, he licked his thumb and raised his hand. I know it's a sniper's way of judging the direction of the wind, it seems that the beard is not blown, he really used to be a soldier.

"How?" I asked.

The beard turned his wrist, and immediately looked at the stone wall behind him, and suddenly his face was happy: "Damn, there is a hole there!" ”

I immediately turned around and immediately saw that on the stone wall behind me, more than a meter above the water, there was a stone cave half a person high!

I finally understood why the water pressure and the air pressure don't interact with each other, it turns out that there is really an exhaust design here, if it weren't for the rising water level, I guess we would never have seen this hole in our lifetime.

"Hurry up." The beard said and began to row with the palm of his hand: "The exhaust hole must lead to the outside world, let's go out first." ”

"Let's go, what about the knife?"

"Since he got rid of us, he must be sure that he will go out by himself, and we can't save him with our skills."

The beard was right, so I gritted my teeth and helped him row. The stone wall was only two or three meters away from us, and we soon reached the bottom of the stone cave.

Still bearded leader, he went up and reached down to me, at this moment, the water suddenly exploded with a bang, I looked back, just in time to see the water worm rushing out of the water, two pairs of giant claws one by one, grabbed at me.

I screamed in my heart, "Mom, isn't it? Got the python out so quickly! While he was busy trying his best to climb into the stone cave, he just got into the stone cave, and suddenly felt his back tighten, and the whole person was dragged back at once.

I screamed and looked back, and immediately saw that the guy's ugly head had poked over, the giant claw hooked my backpack tightly, and the jaw was about to pounce, at such a distance, I could clearly see its fangs like jagged teeth, and smell the fishy wind in its mouth, and suddenly my brain was dizzy, and my heart said damn it, bad breath is so bad!

The thought flashed, just as the jaw of the thing was about to touch my neck, I instantly inserted the pistol into its mouth, with a few muffled sounds, the bullet burst its head at once, and the foul-smelling green liquid sprayed my face in an instant, at the same time, the beard took the opportunity to pull out the dagger from my waist, and quickly cut off the giant claw, I didn't care about the nausea, immediately flew out a few feet, kicked it into the water fiercely, and then turned around and crawled all the way, I don't know how far to climb out, the beard pulled me back, panting and breathing: "Don't run, didn't keep up, eighty percent hung up. ”

I wiped my face, smelled the stench of the body fluids of the water worm, and thought that I had really walked around the ghost gate just now, and my heart palpitated, and my hands began to tremble. "That thing can't be gregarious, right?" I looked around warily.

The beard will not be able to, the water worm is particularly fierce, and after a nest comes out, it will look for its own territory, and it will soon be eaten away by the same kind when it gets together.

Only then did I put my mind at ease, and my beard patted me and said, "Don't rest yet, let's talk about it when we go out." ”

I thought about it too, took a sip of water and took a breath, and immediately followed my beard to the depths of the cave. In the meantime, I took a closer look at this stone cave, there is no trace of artificial excavation, it is completely a natural formation, and a closer look at the top of the cave can be seen, there are many uneven bags hanging down on it, I have studied geology in college, I know that those are incomplete development of stone stalactites, this is a very young underground cave! However, it is relatively dry here, and it seems that the stalactites have stopped growing, and it is estimated that the underground river here has been artificially modified and the river has been diverted. Damn, what a big project is to renovate the underground river? To what extent is the owner of this mother's tomb?

Thinking that if this is an underground karst landform, I can't help but be a little worried, this kind of underground rock structure is very unstable, the formation of rock caves in all directions, it is easy to get lost, and it is not so simple to get out.

Sure enough, after we climbed out for more than ten minutes, the front suddenly opened up, and three forks appeared. The beard suddenly stopped and looked back at me: "How to go?" ”

My heart says how do I know? But I still subconsciously took a closer look at the three holes, and in a flash, I noticed that on the first hole on the left, there seemed to be something flashing, but when I shone the flashlight on it, I couldn't see it again.

What's going on? Could it be that I'm hallucinating? I shook my head and moved the flashlight to the next hole, where something lit up again.

The thing was glowing green, I was shocked, and hurriedly transferred the flashlight back again, with the memory of the flash just now, I suddenly locked the location of the flash, and after a closer look, I found that there seemed to be something stuck in the stone crack on the side of the hole.

At this time, the beard also noticed something strange, walked up to take a closer look, and said, "How can there be such a thing here?" As he spoke, he dug his hand into the crack in the stone and pulled out something the size of a large bubble gum.

I walked over and took a closer look, and it turned out to be a pocket watch! I took it and looked at it, and found that the lid was open, and the shell of the pocket watch had rusted off, but the hands showed no signs of rust, and it seemed that the waterproof of this watch was absolutely level, and the hands and numbers on the pocket watch were plated with a layer of green substance, I think it should be fluorescent, otherwise it would not be shiny. The pocket watch is rusted like this, it must have been around for many years, it won't be left by Li Laohan and them, so who will it be? Could it be the reactionaries who fled in those days?

The beard shook his head: "No, this kind of luminous technology has not been applied to watches at that time, I remember the luminous watches that only appeared in the eighties, and I look at this pocket watch, at most it is something from the seventies and eighties of the last century." ”

"Seventy or eighties?" I said, "According to you, apart from those reactionary elements back then, there are other people who have come in here?" ”

Hu Zi said: "It doesn't matter who came in, what matters is why the pocket watch appears here, do you think it will be a mark?" If, as you said, there is a pattern here, and the caves are intricate, then the people who come in will definitely leave marks along the way. ”

I nodded, yes, anyway, we don't have a choice now, so let's go this way.

Beard also nodded in agreement, and then drilled into this stone cave, about seven or eight meters, and then Beard suddenly sighed and stopped.
