It's been a while, but the monster has managed to find the key to the "buzhou mountain" , which is a portal in the universe that can be used to open up other dimensions. The key, says the monster, is the only key he knows that's not locked away at the jiuli house. The other key, he says, is kept at the other side of the mountain, at the "taiyin youying" . The monster asks the master of the house to give the key back to him so that he can use it to unlock the other dimensions of the universe.
