{Chen Yan} of the Municipal Criminal Investigation Detachment has been able to see "things" that ordinary people cannot see since he was a child. A bizarre "self-immolation case" broke the peace - the deceased repeatedly chanted "The old world is coming back" before his death, and strange runes that did not belong to modern times remained at the scene.
During the investigation, he met the enchanting bar owner {Su Mei}. The woman smiled brightly, but she always left vague traces at the scene of the murder. What's even more troublesome is that the masterminds behind the scenes have appeared one after another: the psychologically twisted "Stitch Monster", the yandere and paranoid "Copycat", and the far-reaching "Old World Believers". They use supernatural means to create serial murders, forcing the world to make a choice between the ignorance of the "Old World" and the order of the "New World".
{Chen Yan} holds the ancestral evil-suppressing compass, while solving the supernatural puzzle, while dealing with the good and evil {Su Mei}, only to find that all the murders point to the "Old World Sacrifice" that was deliberately covered up twenty years ago, and he himself has long been a key piece in the chess game.
