Cultivation, but with a School Life System

Xu Chen transmigrates to a cultivation world and suddenly awakens a System. He thinks his chance to turn his life around has come, only to discover it's a school-development System. He can only earn rewards by training people to become singers, actors, and female CEOs.

Where am I supposed to find those people in a cultivation world?

Xu Chen can only use the knowledge from his past life to teach his students: turning tone-deaf singers into ordinary ones, making chuunibyou even more chuunibyou, and teaching expressionless students to show a range of emotions...

A few years later, Xu Chen stares pensively at the Sword Immortal, the world's top assassin, and the leader of the martial world. You call these people singers, actors, and female CEOs?
