The story opens with a creak at the evil museum. It's been a while since we've seen it, but it's still creepy. It turns out that the curator of the museum is actually a student named Qianxi. He's a poor guy who's trying to scrape together enough money to pay his tuition. He tells us that he's looking for a job. He wants to be a nude model, but he can't find a job anywhere else. The workmates at the museum think the curator is a weird person. They also think that he eats people. The back zipper on the museum's door is broken. The curator needs to get dinner with him tonight. Qianxi tells us the story of the bloody ball. It was bought by the classmates. The ball is in a hole in the ground. The hole is so deep that the ball just rolled in it. The bugle call and the rustle of the bugle are all signs that the bug is in the hole, and Qianxi wants to know what's going on. He doesn't want to go to the creepy museum anymore, he tells us. The case of the dismembered body has been found again in the mountain forest. The major case squad is involved in the investigation. The kid wants to go back to the museum, but the curator won't let him.
