I continued to walk forward, slowly looking at the bluestones on the wall, all of them were trapezoidal, and after walking a short distance, I came to the room. I carefully searched the inside of the room, but there was no flaw, and C was made of the same rectangular bluestone, the only difference was that there was no exit on the other side of Ding, it was a dead end. It seems that there are no clues in this room. I walked slowly back down the passage to C, and this time C was still C, unchanged. However, I came to C through guò B, which means that C must have another passage to B.

I returned to the door of the C passage and continued along the left side of the passage. At this time, I found that the bluestone of the passage was not a trapezoidal body! It's a cuboid again! I immediately shone my wolf's eye on the wall to the right of the passage, and found that the bluestone of the wall was trapezoidal.

I understood, and as I expected, I was bewitched by the clever design of the room. The left wall of the passage is made of cuboids, and the right side is made of trapezoidal masonry, which leads to the different curvatures formed by the walls on both sides. The stone wall on the left side of the cuboid moves forward in a straight line, while the stone wall on the right moves forward in an arc. In addition, the passage is very wide, and people will instinctively choose to stick to one wall in a dark and unfamiliar environment out of self-preservation, so they will be led to different rooms by sticking to different walls. In other words, along the left side will move forward in a straight line, while along the right side will gradually deviate from the straight direction. If I'm not mistaken, going along the left wall will lead you to Room B. After walking for a while, I found room B. It seems that the ghost wall designed by Qi Jiguang still hasn't been able to get rid of the basic principle of ghost hitting the wall, and the subtle differences between the two sides have created different results.

After figuring this out, I was much more relieved, and immediately came out of room B, walked along the other wall, and sure enough, I arrived in room A. And through room A came to room E, and from room E to self, and then to B. This qiē is clearly explained. Knowing the basic structure of the ghost wall, I felt much more at ease. It seems that the fat man and Shirley Yang are also trapped in the ghost wall and can't get out. I will hurry to them, lest they be in any more danger.

At first, I was in a state of chaos because I was too anxious to find Shirley Yang, but now that I understand the truth, it seems that I am beyond the design of this ghostly wall, and the criss-crossing passages are very clear in my eyes, as if I have a blueprint in my heart. I went in the direction the fat man had run to him, and sure enough, it was some new room, but it was basically the same as I had expected. This time, I was no longer reckless because I was in a hurry, but carefully observed the bluestones on both sides of the passage, and looked for the fat man room by room.

I had just reached the door of a room when suddenly a strong wind came in front of me, and I subconsciously lowered my head sharply, and there was a bang, the sound of some kind of iron object hitting the wall. Before I could straighten up and another strong wind hit, I rolled on the spot in a hurry and easily dodged. Before I could stand up, all of a sudden, I shouted, "Fatty! Your uncle's! It's me! The sapper shovel that came to him stopped the momentum, and the fat man threw the sapper shovel and dragged me up from the ground and hugged me: "Old Hu, where have you gone, this city tower is so weird, I've been around for more than an hour and still wandering around here." If you don't come again, I'll have to plane the wall. ”

I was almost out of breath by him, so I quickly broke free from the fat man's arms, rubbed my buttocks that was hurt just now, and said: "You are really not long-hearted, and you can't see who comes up to pick up the shovel, if I dodge slowly, you will be treated as a watermelon now." It's a good thing you don't have the brains to shoot in the heat, otherwise you'd have waited to bury me.

The fat man ignored me and quickly asked me: "Old Hu, is this a ghost hitting the wall?" I'm sweating in these rooms, I can't get out, and I don't know what happened to you and Shirley Young. How did you find me? ”

I briefly told the fat man the principle of this ghost hitting the wall, and the fat man slapped his thigh and said, "Fuck, I said how I can't get around." I remember that we once encountered some soul ladder in an ancient tomb in the Western Zhou Dynasty, and it seemed that the fucking used this principle, anyway, it accidentally made people fall on the road. Do you say that these ancients were all idle, not thinking about anything else every day, and studying how to trap people. ”

I said: "This old dragon head was built by General Qi Jiguang, in order to resist the invasion of the Japanese invaders, maybe he built this ghost wall so that if the unfortunate Japanese invaders enter the city tower and can trap the Japanese invaders." ”

The fat man said strangely: "I remember the last time I was in the Soul Ladder, you said that this kind of inconspicuous little illusion can only deal with the situation of few people, if the Japanese really invade, thousands of people rushed in, and the underground was full, what the is the use of hitting the wall?" ”

I was stunned, the fat man was right, ghosts hitting the wall, hanging soul ladders and these things can only trap a few people, once there are more people, it is useless, why didn't I think of it. I patted the fat man on the shoulder and said, "Okay, little fat, I've made enough progress, and now I'm able to draw inferences." It seems that nothing can stop a heart that pursues progress. For a while, I really couldn't figure out what this ghost was for, so let's go find Shirley Yang quickly. ”
