When the male protagonist was working the night shift at a funeral home, he was forcibly pulled into a dungeon of the Strange Realm and bound to the [Strange Error Correction System]. With his extreme observation skills, he broke through the taboo rules of burial and passed through the dungeon for the first time to save the female protagonist. At the same time, he discovered that the system was highly bound to the notes left by his parents.
The male protagonist then teamed up with the female protagonist and the old ghosts who were secretly protecting his parents, and went through six dungeons of Chinese folk customs. They gradually uncovered the truth behind the disappearance of his parents, uncovered Xu Jingshan, the mastermind behind the scenes, and found complete evidence that he used living people to conduct illegal experiments on rules. In the end, he reunited with his parents who had been missing for ten years in the ultimate dungeon "Returning Soul Village", and they joined forces to destroy the experimental base, bring the villains to justice, and completely end the game of the Unexpected Realm. The male protagonist also grew from an undertaker looking for his relatives to a guardian of the rules to protect the innocent.
