Carrying the system, Chen Feng traveled through Hong Kong, holding the police badge in one hand and the gang in the other, starting a two-front counterattack. In the police station, he relied on Lei Luo to attack dissidents and was quickly promoted from a new police officer; on the streets, he conquered scattered gangs, fought against the forces of Ma Jianshan and Yan Tong, and controlled the core areas of Yau Ma Tei and Mong Kok. He used a combination of police and gangsters to balance the forces of all parties, resolve life and death crises one after another, and finally broke the comprehensive pattern of Hong Kong and became a hero who could not only hold police power but also intimidate the world.
