[Criminal investigation + metaphysics + exciting unit case writing + high-density reversal] No cheats, no system.
Su Wan, the iron-faced captain of the criminal investigation detachment, only believes that "physical evidence does not lie" and relies on hard-core forensic technology and criminal investigation logic to repeatedly solve strange cases, but he stumbles into a serial ritual murder case. There were no fingerprints, no DNA, and no witnesses at the scenes of the three murders. The murderers seemed to have disappeared from the world, and modern criminal investigation methods had completely reached a dead end.
In desperation, she found Lin Yi, the successor of Meihua Yishu, who was regarded as a "magic stick" by the police force. The folklore professor used only three copper coins to predict the location of the murderer's next crime, and even predicted the murderer's modus operandi.
One is fighting for evidence, the other is believing in secrets, from mutual opposition to tacit cooperation, the Liuhe Soul Suppression Formation, the Seven Stars Borrowed Murder Case, the Nine Palace Soul Locking Bureau... Behind each of the strange and murderous cases, there is actually a shocking secret that spans nine hundred years. When the hexagram finally points to the most unexpected person, with irrefutable evidence and heavenly secrets, who can reveal the final truth?
