What Happened to the Plumber? Still Talking Nonsense

[Urban ghost stories + regular professional ghost stories + single female protagonist] Chen Yan, as the "Trouble Terminator" who knows the most about circuits and pipelines in the market, accidentally triggered the entrance to the parallel world and activated the [Plumber System] while repairing an old house. After being bound to the system, he was forced to travel through a copy where strange rules and supernatural events intertwined - from a residential building where the elevator stopped late at night to a hospital that was always short of water, from a school laboratory where circuits kept tripping to an urban village where water pipes leaked blood. Seemingly ordinary water and electricity skills: repairing circuits, clearing pipes, and replacing valves, turn out to be the key to breaking the situation in the dungeon... While pretending to be a pig and eating a tiger to hide the system's trump card, he joined forces with Su Wange, a copy survivor whose fate was entangled, and made a comeback in the hunt of hypocritical NPCs, blackened teammates, and revengeful monsters. He gradually revealed the system's ultimate mission of "repairing the abnormal world" and the causal ties between the two that had been erased in their previous lives.
