Ning Yu is reborn in the Cangming Realm as a personal disciple of the Lingxiao Sword Sect.

In this world, where sword cultivators are caught in a vicious race to outdo one another, his dream is to become a legendary Sword Immortal.

But then his master dumps the task of teaching his junior sister, a princess with a terrible case of princess syndrome, on him. She puts him through the wringer until he can barely take it.

Then one day, Ning Yu awakens the Earnest Guidance System.

Correct his junior sister's bad habits, teach her how to conduct herself, and make sure she works hard at cultivation...

No matter the area, whenever his junior sister makes progress, Ning Yu earns rewards and grows stronger.

And so, Ning Yu takes off...
