Super sleuth Zhao Yunlan meets unsuspecting university professor Shen Wei and the two men are drawn together; they strike up an unconventional friendship and soon find themselves at the heart of a high-stakes supernatural battle.

When Li Qian's grandmother passes away, Zhao Yunlan and Shen Wei try to figure out what it means; meanwhile, more people from Dixing suddenly appear on Haixing and a Sundial pendant reveals the truth in more ways than one.

After a student is found prematurely aged and dead at the campus, Zhao Yunlan suspects a girl with gloves is somehow connected to the case and tries to piece all the clues together.

After a woman is murdered and found without her face, Zhao arrives on the scene and finds Shen Wei already there; the woman's friend claims he saw the killer and is determined to avenge his loved one.

When a man and his fiancée disappear, Zhao suspects their butler knows more than he's admitting and seeks to uncover the plot behind their disappearances.

When a woman disappears from a locked bathroom, the case is handed to the SID; after Zhao consults Shen Wei, they try and solve the mystery with their combined knowledge of dark energy and Dixing.
