Lan feels a sharp pain in the lower abdomen, so Tong takes her to the doctor; along the way, they run into Ching, who offers to accompany them to the hospital.

Tong needs Tak to swear an oath that he has never wronged the Koos in any way; Leung has a crush on the teenage girl Wing Chi-Yau; to get her attention, he and his brother Koo Yu-Yan pretend to offer free medication to the public every morning.

Tong promises Chairman Tsui that he will provide evidence within a week; if he fails, Au Yeung Biu Boxing School will be expelled from the Guangzhou Martial Arts Federation; Lan is so worried about Tong and the boxing school that she has fallen ill.

Suspecting that Wing Tak killed his father-in-law Au Yeung Biu and Biu's second life Hau Ho-Fa, Koo Kin-Shing hatches a plan to lure the man out.
