Master, please stop your playful behavior

Shan Yunhan, the guardian of the demon world, infiltrated the Xuanyuan School, the number one sect in the cultivation world, and was forced to worship a playwright as his teacher.His master, Feng Yixue, was domineering and cold in front of others, but miserable in tears behind him.Everyone told him openly and secretly that his master was the best person in the world to him.Make an exception and accept him as a disciple, punish him for an accident, and even cut his blood to recuperate his wounds.But he especially wanted to tell those people that everything Feng Yixue did was a conspiracy! ! !Just because their identities have been swapped.This master who has treated him so well is the protector of the Demon Realm, and he is the real closed disciple of the head of the Xuanyuan Sect! ! !His playwright master is not only the chief culprit who intermingled the body and soul of the two of them, but also the bloody enemy who stabbed him ten years ago!He didn't say anything about the misfortune before, but now he's consuming his spiritual power, occupying his cultivation base, and not even leaving him a fig leaf! "Good disciple, be obedient, and call Master to listen. Otherwise, just..." "How about it?!" Come and teach me well, let you know what it means to be gentle with others..."
