After a human boy meets a cat demon:
There are monsters in the library, there are monsters in the toilets, my first love is a monster, and I am also a monster.
Yuan Dajun trembled: Why do you all want to eat me?
Group of demons: Your blood can greatly increase our demon power, and your flesh can enable us to ascend as soon as possible. There is a mysterious power hidden in your body. If you get it, you can dominate the demon world.
Yuan Dajun: What, you are my aunt
Jiang Miaomiao: You have inherited that person's bloodline. I love you more than life, and I will protect you for all my life.
Yuan Dajun: I just hope that there is no such thing as sex in the demon world, otherwise I might as well die.
