Ma Wenming, who accidentally traveled to the world of cultivating immortals, was forced to awaken to a strange system. It was a system for doing good deeds, but the rewards were demonic cultivation. What was even stranger was that the people around him seemed even stranger.

Yandere! Yandere! Yandere!
