The fat man saw that I didn't speak for a long time, and asked me again: "Old Hu, you said that when the abbot saw that we were gone at dawn and the kitchen was so messy, would he guess that we were trapped in this dilapidated house and rescued us?" ”

Shirley Yang shook his head and said, "I don't think this door was closed from the outside, but it looks like it was closed by touching some mechanism." Don't you think it's strange that there is a secret room with a trap in the temple? I guess the door of this chamber is used to keep trespassers in. ”

I nodded and said, "Yang Shen is right, there must be a big secret hidden in this Dust Washing Temple, and the abbot or monk in this temple may be the guardians of the secret." I have a hunch that we're going to find something tonight. The fat man wiped his sweat and said: "Don't mention what I found, it's good to be able to get out, if we don't go out, the three of us will have to suffocate here, and now I feel a little out of breath." ”

As soon as the fat man said this, he reminded me and Shirley Yang, and I quickly inhaled hard, and sure enough, I felt that the oxygen was a little thin, and it seemed that it would not be long before the three of us would die of lack of oxygen. Seeing this, Shirley Yang said: "Old Hu, it's useless for us to wait here, if the monk is really the guardian of the secret, then they will definitely not let us out." Let's carefully find out if there is any other way out of this house. ”

Shirley Young and I carefully searched the walls and the ground with wolf eyes, and the fat man was still holding a paratrooper knife trying to pry the door open. The walls were still as smooth as a mirror, and there were no objects or marks to be seen. Suddenly, when the wolf's eye swept over the northwest corner, I noticed several small black objects at the corners of the wall. I took the flashlight and pointed it at the black objects to take a closer look, and found that it was a row of nine small nails like cement nails nailed to the corners of the wall, because the wall absorbs light, so that the flashlight shines on the place with a lot of shadows, these nine nails are nailed into the cracks of the corners, and they can't be seen without careful inspection.

Shirley Young saw me staring motionless at the wall, so he walked over and illuminated the spot where my flashlight was shining, and the nine nails were clearly visible. Shirley Yang said in amazement, "Old Hu, this is the ......" I leaned over to the wall and carefully examined the nails, each about the thickness of a little finger, one end was driven into the wall, and the other end was topped with a disc about the size of a fingernail, dark and shiny. I lightly touched the nails with my paratrooper knife, making a sound of metal colliding, and it seemed that the nails were made of fine iron.

The fat man just sat on the ground and watched me and Shirley Yang's actions without making a sound, and when he saw me carefully taking a knife to test the nails, he stood up impatiently and said: "I said Lao Hu, a few broken nails are not made of gold, why are you putting on this posture for fear of being broken?" I ignored the fat man and continued to look at the nails one by one. Shirley Yang said to the fat man beside him: "There is nothing in this room, except for these few nails, and they are embedded in such a hidden corner, obviously I don't want people to find out." So, I think the nail should be the traction that opens some mechanism. ”

What Shirley Young said was exactly what I was thinking, these nails were indeed too abrupt in this empty house, and they must have had some other purpose. But I don't know what these nails are for, or how to use them. Seeing that I hadn't spoken, the fat man was a little anxious, and said, "Old Hu, if you don't go out again, you're going to be suffocated here." You and Yang Shen are so calm and relaxed, I can't breathe. "I looked back at the fat man, and sure enough, he was gasping for air, and it seemed that some of the oxygen in the room had been consumed. I comforted the fat man and said, "Don't worry, I think Shirley Yang is very reasonable, these nails must be some kind of mechanism, but I can't guess what each nail is used for, I don't dare to move it casually!" ”

"Guess what the, you'll know what you're doing when you pull it off." The fat man began to make a mess as soon as he was in a hurry, and he grabbed the bottom nail and pulled it out. Shirley Yang and I were shocked to see the fat man's mistake, and rushed up to break the fat man's hand, and the three hands were so bad that they pressed the nail into the wall, leaving only the black disc exposed. The three of us were stunned, not knowing if the mechanism was touched, and no one moved for a while. Just as he was stunned, a two-foot-square piece of ground in the middle of the room slowly sank, revealing a deep black hole.

The fat man probably passed over, and when he saw the black hole, he asked me softly, as if he was afraid that speaking loudly would alarm something in the cave: "Commander Hu, did you send someone to investigate?" I nodded and said, "Deputy Commander Wang's mention is good, then you can go." The fat man gritted his teeth and said, "Lao Hu, you are really a villain who forgets his righteousness, and he is reluctant to send Yang Shen, so he will send me." Anyway, fat man, I'm not a person who is afraid of things, I'm going to see what is in this hole that can scare me, and let you see what it means to be brave. With that, he took the wolf's eye flashlight and slowly rubbed it towards the entrance of the cave.
