The main cast, including Andy Yan, Louis Liu, and Tony Ying, along with action director Kar Lok Chin, appeared at nine o'clock in the morning. The crew first filmed the scene where Andy Yan, dressed in a suit, leads Tony Ying and others as they run around wildly with guns. To avoid affecting nearby shops with the subsequent explosion sounds, the staff went door-to-door to notify everyone, even hanging up black cloth to shield the area, preventing any unintended harm. When everything was ready, a sudden downpour occurred, causing great distress for both the cast and crew, who scrambled to find shelter.
