Raising the Villain for Those Years

Shangshen of Penglai, Shu Yun, accepts an old friend's request to protect their son through his tribulation and picks up a pitiful little apprentice along the way.

Unexpectedly, after she completes her task and leaves without a trace, the little apprentice left behind in the mortal world actually falls into darkness, stirring up blood and rain in the Three Realms just to find his master.
