My Traitor Became a Little Fool

[I can't write about cultivation anymore, please slow down orz first] I once had a disciple who betrayed his master for a demon cultivator, making me a joke in the cultivation world. After twenty years of separation, I picked him up in the mortal world, and he became a fool living on the streets. This fool has forgotten the grudge between us and wants to be my Taoist companion. * First person main attack Master attacks & apprentice receives Mission: Not to be defeated by adversity.
