Start with Killing Wujing

No system The world where Jiang Xiuyuan lives has just recovered its spiritual energy. Due to the lack of mature martial arts, the mastermind behind the scenes sent him to a mysterious world where humans and monsters coexist. "I need you to learn and master the cultivation techniques of this world, and then bring them back." After saving the little girl who was almost killed by the monster, Jiang Xiuyuan finished his evil work and killed the fish monster. "One less, why is there one less?" Demon King Sun Wukong cried out, holding his head. "I think the benefactor looks ugly, like that demon who entrusts the world. You can take the vacant spot." The fat monk said with a smile. This is the story of the four people traveling westward who are destined to be absent.
