Hong Kong Underworld: Rise of the Kowloon Kingpin

Transmigrated into the body of a murdered gangster's younger brother, he inherits a bloody legacy and a city that shows no mercy. With enemies closing in and nowhere to run, a mysterious system awakens—his first mission: survive. Armed with system rewards that push him beyond human limits, he recruits ruthless allies, claims the lawless Kowloon Walled City as his throne, and begins a calculated ascent through Hong Kong's criminal underworld. Every rival crushed brings him closer to the top, where power, wealth, and a growing harem await.
