KAN-YE took on the secret mission personally and left for Shanghai. But YU- HIN stopped him because he is still unfit, and went for him. YU-KAI overheard about the conspiracy towards his brother, and told him. While being doubtful, YU-HIN found prove. In his anger, he left shanqhai and went back home. HQ-FU disapproved of his father’s behaviour and they had a fight. The revolution party had a warehouse where they hide firearms for later use. It's next door to the YU's warehouse. YIK-HUN arrived at the warehouse and saw the place had been searched. He was caught later when HA-MAI found the firearms hidden in the tea warehouse of his father.
