The protagonist Chen Zixiao has been able to see various monsters since he was a child. As he gets older, monsters come to his door to help him solve his troubles. Being assigned to the last class in the school, he and a group of poor students accidentally collided with various monsters and caused many ridiculous farces. I would pour a Coke and an earthworm would suddenly jump out of the glass. I went to take medicine, and there was something like a sticky starfish lying on the medicine box. What else could I do? I had to drag my groggy head to sleep. Unexpectedly, as soon as I opened my thick, soft and lovely quilt, I saw a huge green frog squatting inside. It was looking at me on the bed with its round eyes.
