Xie Yun, 24, is a brilliant folklorist and a part-time yin-yang master.
He always speaks with a smile, yet his fingertips trace talismans no ordinary person can see. He says:
"Ghosts aren't here to kill people, Captain Lu. They're error codes spit out by this world's bugs. They're here to... seek justice."
And so the most rational law enforcer and the most metaphysical problem-solver are forced to work together.
Their daily routine goes like this:
At a haunted house crime scene, Lu Chen checks for fingerprints while Xie Yun questions the spirits.
In the autopsy room, the coroner performs an autopsy while Xie Yun "questions the corpse."
In the interrogation room, Lu Chen gets inside the suspect's head while Xie Yun... reads their face.
Lu Chen: "None of this is scientific."
Xie Yun: "But the case-solving rate is 100%."
