Siheyuan: Are You Crazy? This Is Called Beast Control.

I traveled through time and came to the Siheyuan, and accidentally opened the beast control system, but it was a little bit cheating. For example, the beast-control cockroach, since it crawls into the shell by itself, becomes a small cockroach. The beast-controlling mosquito turned into a blood-sucking mosquito. It was really a system that made people vomit blood. But fortunately, mainly if the beasts in the courtyard are frightened, then the host will receive generous rewards. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
