"Shit, I was cheated by this guy." when he got up in the water, I saw that all the meat pieces with anesthetic we had just thrown into the water were vomited out by him. I couldn't see that this thing was very powerful. I could actually find that there was a problem with those meat.

I don't have time to consider the details. I want to protect my companions from floating and running for their lives. In the idiom, there is a mantis to block the car, and in real life, there is a monkey to block the snake neck beast. However, this thing is more flexible than fish in the water. In the dark water, I only saw its cyan gray figure flashing in the light column of the diving flashlight, and then rushed close to us. With its head tilted, it knocked me away, swam to the position above our four holes, and then swam around like a patrol.

Although this hit me seven meat and eight vegetables, I began to wonder: "is it full and not interested in us?" this was my first thought. However, my fluke was soon broken by the cruel reality. Every time we wanted to bypass it and return to the lake from the hole, we would be hit by it. It's reasonable to say that with its size and flexibility, it's easier to bite us than a cat catching mice. What does it do every time it takes the trouble to drive us back? Does it like to eat live, ready to raise us for a few days, and then move chopsticks when it is hungry? That's a reason, too. Even if it wants to raise us as pigs and kill us in the new year, we can use oxygen for less than 20 minutes at most.

I made a crossbow gesture to Sanmei, and Sanmei shook her head. In fact, I know that the Kunlun crossbow is a sharp weapon in killing demons and ghosts, but it is a normal life between heaven and earth. It is the same as the four human beings who bite the oxygen cylinder. They also have the right to enjoy everything in nature, Therefore, the sky killing Kunlun crossbow will not have an effect on it.

Seeing that the oxygen index was getting closer to the warning line, I couldn't help being anxious, but it was useless to be anxious. The more urgent the oxygen consumption was, the faster. I gestured to my companions to look around to see if there was a channel to enter other underground waters.

These four people, except Ivan, are all rolling at the edge of the knife all year round, so their psychological quality is relatively excellent. Even if Ivan was afraid, he was embarrassed to show it. The four immediately swam separately to find an exit.

Just below the vertical part of the entrance, there was the strange building with two floors high and half the size of a football field. I wanted to search for the exit around the four towers, but I was attracted by several human statues on the platform on the top of the tower. I stopped to have a look. Unexpectedly, I saw more suspicious places.

On the square top platform of the tower, four black stone men stood in four directions, East, West, North and south. They were almost as high as normal people. They looked very strange. Generally speaking, this kind of ancient architecture has some decoration, which is very normal. For example, the gate of the wolf palace where we rob the Buddha's head is filled with cast-iron axe holding werewolves.

However, these four stone men look strange. They are decorated or symbolic portraits. Generally, they are either kneeling slave soldiers or armored warrior generals. However, these four stone men are bare and their hands are chest high, like doing radio gymnastics. The expressions of the four faces are either ferocious and terrible, or thinking with frozen eyes. They are very vivid, just like the faces of living people under the black water.

Seeing such a strange building, I was curious. I wanted to spend half a minute to take a closer look at the nearest black stone man. When I was close, I looked up and down. Suddenly found that the stone man's feet are connected with a circular turntable, and the material is the same as the stone man, which seems to be one.

Trying to push the stone man's outstretched hands, I was surprised to find that they can rotate and are very flexible. They should be connected with some mechanism under them. I immediately adjusted the brightness of the diving flashlight, increased the intensity of the light column to the maximum, and then rushed to several companions to draw circles. The three of them also responded to the signal a few times, and then quickly swam back to me.

While the three of them swam back, I lay down at the foot of the stone man and cleaned out the mud, water and grass, which made muddy water everywhere. However, I could see the disc of the stone man standing by using a diving flashlight from a close distance. Just now when I was cleaning the mud by hand, I already felt something engraved on the stone plate. When I looked carefully, it was some strange symbols, composed of points, horizontal lines and a shape like a shell. All symbols form a whole circle on the periphery of the black stone plate, which is a bit like the concept of 360 degrees in modern geometry.

Just as I was observing these symbols, the three companions swam over one after another and came up along the light of my flashlight to observe the symbols on the stone plate. Their faces were mixed with expressions of surprise and confusion.

Sanmei responded first, pulled through the underwater tablet, wrote "password disk" on it, and drew a question mark behind it.

Seeing these words, we nodded and agreed with her. The black stone man in front of us, together with the other three, should constitute some kind of password mechanism, but what is the purpose?

Ivan suddenly began to push the stone man's hands and turn them. It seemed that he wanted to use the exhaustive method to see what would happen after the password was entered. I took his hand and stopped this meaningless behavior. These four combinations are equivalent to a set of passwords composed of four digits. Each digit has 360 possibilities. The possible combination has a power of 360. Although I can't get the result by mental calculation, I know it will be an astronomical number and it is absolutely impossible to crack it in these 10 minutes.

Just when we were in a daze, the snake necked beast blocking the hole didn't let us out, suddenly swung its fin and tail and swam straight to us.

"He's going to eat?" I felt the underwater pistol, ready to find a chance to blind him, and then see if I had a chance to escape.

Unexpectedly, it did not directly attack us, but cruised back and forth seven or eight meters above our heads. When turning back and forth, it occasionally looked back at us.

"What is this thing doing? Do you pray before dinner? Or do you exercise to appetizer?" my mind was confused again. I thought that my mother-in-law might be able to communicate with this spiritual ancient monster here, and maybe let us live after discussion.

We watched it have fun and were ready to swim around it back to the cave, but as soon as we moved, it opened its mouth and made a fierce expression at us. Two eyes stared like underwater searchlights, staring at us.

Sanmei suddenly grabbed the three of us, then pushed the stone man's outstretched arm and pointed it to the direction of the snake neck beast. Seeing Sanmei's action, the snake neck beast put away his fierce appearance and changed it into a happy and excited expression. Then, with a swing of his fin tail, he swam to another stone man.

"The monster is inputting the password for us." with the idea that even I was startled, we turned three other black stone men and pointed our outstretched arms in the direction suggested by the snake neck beast.

As soon as the fourth stone man was placed, a large number of bubbles appeared at the diagonal intersection of the square tower top platform, and a circular stone column slowly sank.

This time there was no need for the snake necked beast to show a fierce expression. The four of us immediately swam there and drilled into the exposed circular hole. Soon after Ivan at the back came in, the fallen stone pillar slowly rose up under the action of the mechanism and stuffed the hole just now.

This time it's completely over. At least there's still a little weak light on the head, which gives people some psychological comfort. But now, when there's no way back, it often forces out the latent strength of human beings.

After shining a few times with a flashlight, we found a square channel. After swimming in, it was a right angle turn. Facing him was a thick stone gate that was bolted up. After opening it, he drilled into another closed waterway and finally drilled out of another stone gate. But at the end of this time, there was no stone gate, but a square sink. After swimming a few more times, I found that the water was getting shallower and shallower. Finally, I stood up from the water.

After testing the air with a lighter and finding nothing wrong, the four of us took off our respirators and eye masks respectively. They were all tired and gasped. Ivan gasped and said, "where is such an evil door?"

No one answered him. They all took random photos with a flashlight. Next to the pool, there were some metal utensils, which were rusty. There are lamps on the four walls, but the oil inside is dry. We got out of the pool and turned to one end of a passage. In front of us was a long row of separated rooms.

"We should be on the second floor," I said somewhat ostentatiously, and prepared to calculate the height of the whole building minus the floor height of the room.

"How clever," Jin Lihua said a rare compliment to me, and then I saw her flashlight shining directly on a group of downward steps, looking at me like a smile. I was so angry that I thought, "don't tell me if you see it."

Along the solid stone steps, we walked down one floor. As we walked, I observed the building material of the tower and found that it was built after cutting with very strong sedimentary rock. It was hard to carve with a diving knife, which left a very shallow trace on it. Moreover, these stones are bonded and filled with some things, which seems to have a very good sealing performance. I just don't know who built such a magnificent project here in what year, month and purpose.

After walking down one floor, I pushed open a sealed stone door. The first feeling was that this floor seemed to have a very charming aroma, which was refreshing. In addition, there were more rooms on this floor, and there was a square large reservoir in the middle. It seemed that there was no problem to raise several great white sharks in it.

Many murals are painted on the walls around the pool, including ancient people fishing at sea, fighting sea monsters, praying for God, offering sacrifices and praying. I'm afraid there are hundreds of murals on the walls around the pool. It seems that the strokes are very delicate, many brush details are done in place, and the characters, scenes and actions are very vivid. Sanmei may be influenced by her father's heredity. She is very interested in these things with art and looks at them alone. Ivan, I and the golden pear flowers are scattered and looking everywhere to see if we can find anything.

Women are always sensitive to scented things. The golden pear flower twitched her nose and found a jade bottle in a room with seven twists and eight twists. The bottle has three sections. The belly of the bottle is large. It is carved from top-grade ruby. It is painted with some simple patterns, and the mouth of the bottle is stuffed with things. But even so, you can still smell a very strong aroma at the mouth of the bottle. That feeling is really light when you smell it. It feels like smoking poison. This is still the case without removing the cork. If you remove the cork, I don't know what the aroma inside is like.

Ivan didn't know which room he was in and found some eggshells bigger than ostrich eggs. Because of the age, they had been broken into pieces, but some could still see the shape.

It was interesting to see what they were looking for. I also turned around to find a very tight door, opened it, and then searched the house.

This room has a thing like a stone bed, on which is a complete humanoid groove. If you hide on it, your head, hands, feet and body will sink in respectively.

"What's this for? Don't the ancient people in this tower like to turn over when they sleep? They should fix themselves." I looked at the stone bed the size of the coffin curiously and found that if they lay down, there was a wrench at the hand on the right side of the bed and pulled it hard. After a few bangs, clicks and creaks, several semicircular blades pop up in the grooves of hands and feet.

"It's not sleeping. It's obviously bleeding. It's really evil. I noticed that after the wrench was pressed, several small sliding doors on the stone bed opened, revealing several stone bottles. This bottle has no plug, and its workmanship is a grade worse than the three section belly shaped jade bottle that golden pear flower found just now. It is engraved with some abstract patterns and illuminated by a flashlight There seems to be something at the bottom of the bottle, but it has dried and stuck to the bottom of the bottle for too long.

After counting almost seven or eight of these ceramic belly bottles, I wanted to break one. I thought that if someone studying archaeology was nearby, I had to smoke me. I wanted to ask Sanmei of family origin to see if she knew what this thing was doing.

Back next to the big pool, Sanmei was talking to Jinlihua and Ivan. When she saw me, she said, "come on, I know what this tower is for. It's a sacrificial tower."

"Sacrificial tower? To whom? Poseidon?" I said jokingly.
