Killing a fat mouse in the dining hall

The two mice in the dining hall have lived in the sewer for a few months. They were not very old at first. Now, the longer they grow, the more fat they are. They have long been trying to clean them up, and they are suffering from nothing. At ordinary times, the sewage mixed with rice grains in our trough will flow into the sewage pipe from the small channel with a cross section of about half a square meter. The small channel is covered with a stainless steel column, and the two mice will hide behind the trough, every time they wash dishes, they will run out and feed in the narrow channel. They are not afraid of people at all. I have driven them many times.
To capture them, I thought a lot of ways, including installing boards in Water tunnels and sewers, and quickly blocking their loops when I saw them for food. Just think about it. It seems that I only saw one mouse recently, and the other did not know where to go. I thought of another solution for breakfast two days ago. Simply put them in a single stick, and I found a spoon discarded by others on the windowsill when I washed the dishes, so I prepared it on the windowsill.
After dinner tonight, I could see a mouse there. So I told the teacher who was about to wash the dishes to leave. I put down the bowl, picked up the prepared spoon, and inserted it in the mouse loop. The mouse squatted down at me and surprised him, so he went back. The water channel is low and it does not run fast. when it passes through the spoon, I immediately squeezed it into the water channel with the spoon. It struggled, and its tail tilted out, which is better, I step on the mouse's tail with my shoes, and I am not afraid that it will run. Then I use a spoon to tie its body and head to it. It wants to bend back and bite me, but there is a stainless steel bar, I can imagine it is helpless, desperate before death. Later, I came to a teacher and helped me boil it with a bowl of boiling water. After a while, the mouse would not move. So I put it up with my tail and broke it's head with my feet, and confirmed it was dead, then, it is thrown into the bucket.
Then I washed my hands and continued to wash the dishes. Some other teachers are scared, some are pity, and some admire me. I just had to find another partner and I gave it a chance.
For me, it was no longer possible to beat a mouse. When I moved my office here, I killed one and all my colleagues went out of the house with fear. When I went home every year, I had to play a lot of mice in my house, because I went upstairs as a granary, and I couldn't sleep until I heard them scream every night. In the middle of the night, together with my parents, I had a big grain-packed pocket at the door of the room, opened my mouth, grabbed a stick in the room, drove the mouse into the bag, and finally killed it, one night at most seems to have been beaten for seven or eight times, killing one after another.
