It is a novel with two male protagonists, the kind where a master is attacked by his apprentice. The routine of rebirth + time travel + system, there will be plots such as the yandere's little dark room.
Zhang Qingyun was confused when she traveled through time in this world of cultivation. The time travel novel does not deceive me. The system wants him to stabilize the world, but he has to take good care of the sources of instability. Hey, just play.
As the elder of Niu Duocuo's largest sect, he not only accepted him as his only disciple, but also allowed him to practice the black and white arts. In the end, the person who created instability in the world made Zhang Qingyun unstable.
It's a subject I've always wanted to write about, and the plot is novel, giving new life to an old subject.
