The bombing gang, aware that the police are on to them, plan a simultaneous bombing of the property company and the police headquarters. They double their ransom demand to $20 million and kidnap May, luring Ka-Kui into a trap in which he is strapped with an explosive vest and forced to pick up the extortion money from the property company. However, after picking up the money, Ka-Kui tells the gang that they are being followed and split up. Ka-kui, still holding the ransom, is able to drive his car into a tunnel so that the bomb he is wearing cannot be activated and he strips it off. He then goes to rescue May, who is being held in a warehouse full of fireworks. Ka-Kui again faces the deaf-mute man, who throws small firebombs at him. Ka-Kui then gains the upper hand and brutally retaliates against the mute man, finally throwing him off a third story catwalk onto a pile of plastic drums below. Ka-Kui then rescues May and departs the warehouse, just as it explodes in a huge ball of fire.
