Life forms on earth are undergoing subtle changes. Due to the lack of some spiritual aspects of personality or character, they gain special powers throughout their lives, even if those powers are not what they want.
(Heshu and Li Weiyang are good friends who have known each other since junior high school. After they entered the same high school, they both joined the student union. Their parents divorced when they were young. Heshu, who was living alone at home, regarded Li Weiyang as his own relative, and Li Weiyang often relied on Heshu, a trustworthy presence like an elder brother. But after meeting the man-slayer, will the old friends become farther and farther away? And will the man-slayer who kills people on the street be the strange girl from the same class in junior high school?)
