Chang Qing was originally just an ordinary person delivering food, but after running into strange incidents again and again, he completely stepped into a dark world intertwined with "doors", "old cases", "half-page accounts" and evil forces. The old cases in Qingxi, Mengen's real name, old co-investigation files, the changed names - behind every line, there is a terrifying old network covering the provincial capital and even wider areas.
When his loved ones were trapped behind the door, the truth was erased page by page. Chang Qing could only rely on his spiritual power to break the trap and dismantle the net again and again, from the door to the bottom, from the old file to the real name. He doesn't accept fate, he doesn't recognize the rules, and he doesn't recognize the forces at the door who want to make people into "closers."
This is not a simple elimination of evil, but a tough battle that completely breaks through the entire old world. What Chang Qing has to do is to smash this door and everything behind it into pieces.
