"Guide to the Underworld: Soul Hunting in Red Makeup"
On a rainy night, a headless female corpse lay quietly in the reservoir, clutching a blood-stained red rope in her hands, and the incantations of the underworld were engraved in her pupils. For the first time, the criminal investigation captain Lu Chen came into contact with the truth "beyond science" - when he pushed open the weird Hongzhuang funeral shop, Yu Hongzhuang was talking to the souls of the dead in the flickering candlelight.
She is a guide walking on the edge of yin and yang, with cinnabar as the blade and yellow talisman as the bridge; he is a law enforcer who believes in evidence and is rational and cold-blooded, but is forced to admit that there are "unexplainable evils" in the world. When serial murders occur one after another, the resentment of the dead tears apart reality, and the two are forced to join hands - he traces the clues in the world, and she explores the unspoken injustices in the underworld.
However, the conspiracy of the "Judge of the Underworld", the mastermind behind the scenes, is far beyond imagination: the cracked underworld passage on the Ghost Festival, the living people swallowed by resentment, the blood debt that has been entangled with the Yu Hongzhuang family for hundreds of years... This duel is not only a matter of life and death, but also affects the balance between the Yin and Yang realms.
When truth and magic collide, reason and faith collide, can this "incompatible" pair find a way out in a city where resentful spirits are raging?
