The fatso turned out to be Zhao Lusi's younger brother, Zhao Zhiwei. He was the youngest of the three siblings but his cultivation was on par with that of Zhao Lusi, his elder sister. This showed clearly that the fat young man was more talented than his older sister or he had access to some precious resources that Zhao Lusi could not access for some reason. After thinking about the situation, Kai Syaoran decided that the latter reasoning was far-fetched.
Zhao Zhiwei looked at the strange man in his sister's pavilion with suspicion but as if he had been struck by lightning, he started panicking again as he tried to explain his problem to Zao Lusi. His words were incoherent. Pa Zhao Lusi slapped Zhao Zhiwei making him stop panicking. He began to explain in clear sentences while holding his left cheek. Kai Syaoran sat by the side on a comfortable chair and listened to the siblings' conversation.
