In the meantime, Mr. Cai's son-in-law, the younger brother of Cai, has returned to the house. He asks his grandfather to let Cai take a bath, but the old man refuses, saying that he'll take care of the girl later. Cai tells him that his name is "xuan wu" , and that his family is from the "noble muchi" family, which means "noble" in Chinese. Cai asks if he's threatening him, and the elder man says that there's a "crab poison" in the water, which will kill him if he drinks it. Cai says that he doesn't want to tell his grandfather that Cai has been kidnapped, so he won't reveal the identity of the person who's been kidnapped. He's not going to tell Cai that the target of his kidnapping has been "kidnapped" . He says that Cai is violating his privacy by using a "cheap trick" like that, and he calls him a "slam !" .
