There are a group of monsters living in the mountains and forests, including kitten monsters, little monkey monsters, tiger monsters, little rabbit monsters, little pig monsters, etc. They live a simple and happy life of cultivation together... However, one day, there was thunder and lightning, howling winds, and heavy rain. When the little pig monster went out to find food, it unfortunately fell into the valley and met an injured 'big wolf monster'. The kind-hearted little pig monster saved the big wolf monster, and then was 'eaten' by the big wolf monster in revenge.
