The mask was suddenly held down by one hand, and then a familiar figure floated past me, stopping not far from the mask, the dagger slashing at the hand, and the arm stirring in the churning water. The mask seemed to be very afraid of blood, and stopped in place with its tentacles waving wildly, but did not dare to move forward. Shen Muhan turned around and pulled me to escape from the mask's attack range, and Wang Chuan also followed when he saw this scene.

Shen Muhan dragged me to a cave before stopping, pointed to the hole and got into it first, I glanced at the mask that was getting closer and closer behind me, and hurriedly followed Wang Chuan into it.

The space of the stone cave is very small, and I can't stretch my arms out, so I can only swim and climb forward. The whole process was very uncomfortable, and if I wasn't careful, my back would hit the rock wall, and after a while, I felt that my back was already swollen. When I couldn't hold it anymore, the space finally became larger, and the direction of the stone cave became diagonally upward, and after continuing to float for a while, it surfaced.

The stone wall in front of you has become a sloping staircase, and it looks like there is a lot of space. Shen Muhan and Wang Chuan had already taken off their breathing masks, and were sitting on the steps panting for breath, when they saw me climbing up, Wang Chuan asked while panting, "What is that?" Why is it so evil? ”

I took off my mask and shook my head without saying a word, thinking to myself that I didn't know that I didn't raise it. Although the air here is not fresh and mixed with a sour smell, but there is no feeling of difficulty breathing, Shen Muhan and Wang Chuan don't seem to be in trouble, but they are more embarrassed, and they are obviously much better after resting for a while.

The stairs are diagonally upward, and the top seems to be a platform, but due to the large number of platforms, it is difficult to see the situation on the platform from the current position. Shen Muhan's hands were still bleeding, and when they came down, the three of them were wearing diving suits, and now there was nothing that could be bandaged, so they could only wait for the bleeding to stop naturally. Wang Chuan rested for a while and asked Shen Muhan how he found this hole.

Shen Muhan shook off the blood on his hand and retold the story.

When Wang Chuan and I collided, the tentacles wrapped around our legs had already been released. The mask pulled Shen Muhan in front of him, his mouth getting bigger and bigger, and he seemed to be very interested in Shen Muhan. Shen Muhan took the opportunity to grab the dagger that Wang Chuan had inserted in the mask and pulled it out, and the mask pulled Shen Muhan's legs in pain and wanted to tear her apart alive. Seeing that he was about to be unable to support it, Shen Muhan touched the dagger on his waist, but he didn't expect that because of the sudden force of the tentacle, the painful dagger almost came out, and in a hurry, he reached out and grabbed the dagger, and a wound was cut on the palm, and blood flowed out.

The mask suddenly became very frightened, and threw Shen Muhan out with all his might, just hitting the position of the hole. At that time, the exit that Shen Muhan wanted to enter had disappeared, and the mask seemed to have no weakness, so he came in along the hole and found the current place, and there was still air to breathe. When I went back to save us, I saw my breathing mask in water, so he fixed it for me. Thinking that the mask seemed to be afraid of her blood before, he cut his hand again, blocked the mask's attack, and took the opportunity to escape with us.

"You all know the rest of the story." After Shen Muhan finished speaking, he blew a few breaths into the wound. Wang Chuan still wanted to continue to ask me to stop, now is not the time to chat, it is more important to find out the situation here first.

"There's still space up there, I don't know what it is, the road outside is impassable, I don't know if there will be an exit from above." I shook my flashlight up the steps. As soon as he finished speaking, there was a sudden slippery and greasy feeling on his ankle, and the whole person was pulled to the ground, and his forehead slammed on the steps, sliding all the way down into the water.

Seeing this, Shen Muhan and Wang Chuan stretched out their hands to grab me but caught them empty, so they could only thrust their daggers up the steps in a hurry, trying to slow down the speed of the slide. The dagger sparked and finally got stuck in a gap in the steps, halting its downward trajectory and sliding half of its leg into the water.

Seeing this, Shen Muhan and Wang Chuan rushed over together, constantly slashing at the tentacles. The mask seemed to be determined not to die, allowing the dagger to continue to fall, and the blue liquid continued to flow out, still stubbornly entangled and refused to let go.

I don't know how many times I slashed, but the force on my ankle finally loosened, and I quickly climbed a few steps up the stairs before I sat down, and the broken tentacles were still wrapped around my ankles, but I didn't have much strength after leaving the mother's body. As soon as I jumped with my dagger, the tentacles fell down the steps, wriggling for a moment and scattering into countless tiny tentacles, and finally turning into a puddle of blue liquid.

"Looks like the tentacles can still get in, so let's go up and have a look." Shen Muhan said a word, and took the lead in walking towards the stone platform with a flashlight.

The steps are all black, I can't see any material, the surface is very smooth, the height of each layer is about more than 20 centimeters, the width is only a palm width, and it is very difficult to stand on it. And because of the connection to the seawater, the surface is very slippery, after walking a few floors, I almost fell, and finally I can only climb up with my hands and feet, although this posture is a lot safer, but it is very physically demanding, and after a while, I feel that my hands and feet are filled with lead. Shen Muhan knelt on the steps to rest regardless of the pain in his knees, and Wang Chuan also lay on the steps like a toad panting. I looked up at the stone platform, there was still a long distance, and I simply learned Wang Chuan's posture to rest for a while.

Just lying on the ground, Shen Muhan suddenly shook me with a flashlight: "Wood, it's not right, you see that we have been climbing for so long, it seems that the distance from the stone platform has not changed." ”

Just now, I have been paying attention to the steps, for fear that one will accidentally roll down, and now that the girl reminds me like this, I realize that after climbing for so long, the distance of the stone platform still seems to have not changed at all.

Wan Chuan raised his head and took a look: "Could it be a ghost hitting the wall?" ”

I gave him a blank look, and squeezed him angrily: "You are an archaeologist, not a tomb robber, what kind of wall do the ghosts hit?" ”

Although Wang Chuan made a lot of money after the run, the situation in front of him was indeed a bit unbelievable. It's been half an hour since I started to climb up, and even if the steps are longer, you should be able to see the changes, so that you won't stay in place, could it be that this is a downward elevator?

I shook my head and shook off the unreliable thoughts, and asked Shen Muhan, "Girl, what do you think?" ”

Shen Muhan thought for a while: "If the distance between us and that stone platform remains the same no matter how we climb, there is a situation where this result may occur, Yuan!" The distance between any point on the circumference and the center of the circle is the same, and if we are in the circumference and the platform is the center of the circle, no matter how we walk, we will never get even a little closer to the platform. ”

After Shen Muhan's reminder, I suddenly understood, if it is really like what the girl said, it can indeed explain the situation in front of me, but after thinking about it, the feeling in the body will not be wrong, we have been climbing up, if it is a circle, it cannot be all the way up, and the stone platform has always been in front of us.

"No, girl, if we climb up the circumference, the center of the circle can't be directly in front of us."

Shen Muhan thought for a while: "Is it a folding space?" ”

Wang Chuan listened for a while and interrupted: "Wait a minute, what are you talking about folding space?" ”

Shen Muhan thought for a while how to explain, and finally gave Wang Chuan an example.

"For example, if you go from the second floor to the third floor, normally you just have to climb up to get there, but when you go up to the third floor, the stairs fold up, and the second and third floors overlap each other, and when the stairs unfold, you go back to the second floor."

Wang Chuan touched his head, looked confused, and wanted to continue to ask, but I stopped him.

"Is it a folding space, just try it, girl, you stay here, I'll go up and try it."

I asked Shen Muhan to keep the flashlight on and continue to climb up by myself. Although the folded space mentioned by Shen Muhan just now can explain this phenomenon, there is a big loophole, the formation of the folded space requires a lot of gravity, and the most likely thing at present is a black hole, this place obviously does not have the conditions for the formation of a folded space, but it makes me think of a method.

I looked up at the situation in front of me while climbing, and after climbing for a while, I saw that there was an extra beam of light on the stone platform above, and I couldn't see the flashlight light in Shen Muhan's hand behind me, I took a few steps back, and finally stopped on the floor where the flashlight light could be seen above and behind me, and groped on the steps.

When I was just climbing, I kept thinking that since there are people who have made this place, someone must come, whether this place is a space folding or a space cycle, there is always a boundary point, otherwise whoever comes will be the same as us.

After fumbling for a while, I felt a bump on the steps not far away, I tried to twist it but there was no response, and with a force on my hand, the bump sank into the stone steps with a "click", and then there was a sound of machine running. Wang Chuan also heard the voice, and shouted vigorously to ask what the situation was. I didn't reply, I stared in the direction of the stone platform above, and when the sound of the machine was completely gone, the flashlight light above disappeared, and a stone platform appeared closer than before.

I thought to myself that this was the case, and as I called out to them, I climbed up the stone platform, and soon reached the end of the steps.

A black gate appeared on the stone platform, and a slit had opened in the middle, and a faint blue light shone out from the crack in the door.
