Yan Fei neutralized the threat above his head and then pivoted the gun barrel to start firing all around. This room was filled entirely with key members of the Assassin Sect; even Yang Wanlin, who had sought to murder Yan Fei, was one of the Yang Family, making everyone present an enemy to Yan Fei. Firing with the 20 millimeter machine gun in this setting, he naturally wasn't worried about hitting any innocents.
Caught off guard by Yan Fei's attack, the Assassins fell into the white smoke without warning. Fortunately for them, they were well-trained and experienced, so even plunged suddenly into such a blinding environment, they didn't descend into panic. Instead, they shouted loudly to quickly organize themselves, trying to locate Yan Fei hidden in the dense fog. Little did they know that Yan Fei would suddenly unleash a powerful High-altitude Dual-use Anti-aircraft Machine Gun, opening fire in all directions.
