The Yong Dynasty lasted for the third year of Yong'an. The barriers of Yin and Yang are loose, and evil spirits are rampant. The imperial court set up a demon town to catch ghosts, and the folk Taoist sects each occupied one side. The two factions fought for hundreds of years, but no result was achieved.
Lin Zhenghao, a graduate of the 21st Century Materialism History Department, was dragged into Dayong by a mysterious copper coin when his grandfather was sorting out the relics of his old house on July 7th. When he woke up, he was lying in a coffin, with more than thirty corpses next to him, all with eyes open without pupils.
He inherited the original owner's body, the original owner's wanted criminal record, and an outrageous physical condition - hiccups when nervous. But in this hellish world, he can knock down ghost generals with just one belch.
The copper coin left behind by my grandfather is the legendary "Heavenly Master's Order", which can absorb the energy of ghosts and seal away powerful ghosts; the incomprehensible fragment records the lost ancient soul-suppressing secret technique, which in Dayong is far more powerful than all contemporary ghost hunters. His partner, Shen Qingluan, is the youngest member of the Hundred Households in the Demon Suppression Department. He has a cold face and a sharp tongue. After watching him hiccup for a whole year, he said, "It's okay, he's not dead." The mentor, Mr. Mo Wen, an old man who was jailed for owing rent, turned out to be a former third-level demon-suppressing general of the Demon Suppression Department.
From a wandering soul to the ghost king of the underworld, from the dark ghost of the Demon Suppression Department to the shocking catastrophe three hundred years ago - Lin Zhenghao uncovered the biggest lie in the world step by step: What the Demon Suppression Division suppresses is not the monster, and what it guards is not the door, but the cage. The cage contains the ulterior and bloody past of the founding of Dayong, and the "soul-locking seal" between his eyebrows is the key to unlocking the cage.
