This novel was called "The Peak of Evolution". It was about the protagonist, Li Fei, who was bullied at school. Later on, he accidentally obtained the ability evolution system and fought against the mutated beasts with a group of posthuman companions. His master was not a spellcaster, but a future person who could help him activate the evolution system. He started to make a comeback at school and defeated those who had bullied him before. I hope you like this fairy's recommendation. Muah ~😗
