During the prosperous period of the Zhao Dynasty, Yin and Yang were out of balance. Even after death, resentment persists, turning into painted ghosts, mirror nightmares, and lantern demons, wreaking havoc in the world.
In Dali Temple, a "Crime Department" is secretly set up. Xie Wuwu, whose left eye is connected to the netherworld, can see the true form of ghosts and gods, and the ice heart of the Miemen is hidden under the warm skin; Su Yexin, with a silver needle to stabilize the soul, and a soft sword with flowing light, walks into the deceitful path in order to find the trace of his sister; Mo Chen, with a right arm to seal the ghost, can control the mountains; Hua Xiangrong, holding a thousand machine fan, knows the ancient and modern secret formations.
The four people jointly hold "Netherworld Records" to judge Yin and Yang, and decide between life and death. From blood lanterns in the streets to nightmares in the east palace, from the resurgence of a century-old ghost king to the riots in the imperial mausoleum of the previous dynasty. However, deep inside the mystery, the shadow of the "Netherworld Sect" emerged, collecting special fates in an attempt to open the door to the underworld.
When the souls of their loved ones are reduced to bargaining chips, and when the people they trust show their ghostly appearance, they realize that the deepest terror comes from the human heart. This is a huge gamble with lifespan as the price and soul as the stake. In the carnival of monsters and monsters, we must guard the last line of defense in the world.
The blood moon is coming, and people will eventually die. What's knocking on your door tonight?
Concept: In the darkness, the glimmer of humanity is the blade of dawn. Explore people's persistence in justice, responsibility and love in the face of absolute terror and despair.
