Di Qing transmigrates to Hong Kong Island and becomes one of the seven undercover agents Han Chen has sent into the police force.
Five years later, his unscrupulous superior sends him undercover to Hung Hing as well, to investigate the criminal activities of Mong Kok's boss, Kwun.
Back then, I had no choice.
Now? I wouldn't be an undercover cop even if I were a dog!
An Infernal Walker? No! I want to be the kingpin of Hong Kong Island!
With his identity as a triple agent, Di Qing rises through the ranks in no time.
In private, he's an undercover agent for the police.
In the open,
he gathers one formidable talent after another under his command: Lok Tin-hung, Tin Yeung-sang, Ah Bu, Siu-fu, Lung Ng, Wong Kin-kwan, Fung Yu-siu, Ho Lik-wong, prison warden Ko Chun, and more. His businesses in entertainment, real estate, finance, trade, and other fields are all thriving...
When he looks back, he has become an international powerhouse feared by all, a kingpin of the entire Hong Kong Island underworld!
Years later, the police come knocking. "PC9527, your undercover assignment is complete. You can return to the force now."
Di Qing, impeccably dressed in a suit and tie, has a cigar between his lips. "Officer, what are you on about? I'm a legitimate businessman. Keep this up and I'll sue you for slander!"
