When urban legends invade reality, when strange rules become the iron law of doomsday, the world begins to collapse.
After Zhao Jue accidentally touched the taboo of the "other world", he was dragged into an endless whirlpool of terror. In order not to implicate his only brother, he was forced to embark on the road to escape.
Knocking ghosts, brain-slicing demons, ancient mountain village gods, insect mother heretics... Faced with these existences that cannot be understood by common sense, Zhao Jue's only weapons are the notes on humanities and customs left behind by his parents as a folklorist after their death, and his weird simulation ability.
By imitating the "Gravekeeper", he can deceive the souls of the dead; by imitating the "Mourner", he can pass through the epidemic area. Every time he "enters the play" is a fatal dance with the abyss, and every victory makes him one step further away from his identity as a "human".
When all the clues pointed to the ultimate forbidden place "Silent Ao", he discovered that the final secret left by his parents was not a seal, but a door to the myth.
