After ten years of killing monsters in the "other world" of the mysterious hospital, Su Wan finally got his discharge certificate. I originally wanted to return to the outside world and be an ordinary person with social terror, but I found that this world was being secretly eroded by unspeakable monsters. Seeing the indescribable weird talk raging on the street, Su Wan fell into deep thought: "That's it? It's not as good as a watchdog in the hospital." When he took out a rusty scalpel and approached with an extremely twisted posture while suffering from illness, the monsters collapsed on the spot: "Where did this living dad come from? Let him go back to the ward!" Although the world is very deep, and there are countless horrors dormant, but who is the real monster in front of him?
