In the cultivation world, there is an ironclad rule: never provoke Lu Xuan. Because his disciples are too overpowered! 
Eldest disciple, Empress Fuyao: She built the Fuyao Dynasty and became the ruler of the Southern Wasteland! 
Second disciple, Ye Chen: A master of both alchemy and martial arts, the Alchemy and Martial Emperor! 
Third disciple, Chen Changsheng: So steady... He can easily destroy an emperor with a snap of his fingers, yet he remains hidden from the world! 
Fourth disciple, Forbidden Zone Empress: My body is tainted with mystery and misfortune. Master, can you help me absorb it? 
... 
Lu Xuan: Me? I'm just an ordinary person, slightly stronger than my disciples by a billion points.
