Due to CHOU's deadly chase, TO and FOK cannot manage to leave the city and hide in CHAN's house. CHOU takes YIM as prisoner and tortures him to make him speak. YIM shows his loyalty by committing suicide for stead of AH LOON's effort to rescue him. CHOU thinks it is AH LOON who kills YIM and is pleased with him. Gradually AH LOON takes up much responsibilities in CHOU's business.
