Hong Kong film: Undercover agent exposed? I turn evil and amass troops.

(Rapid troop build, Darkening build)
In a Hong Kong film, Huo Wenyao discovers that his undercover identity in "Infernal Affairs" has been exposed.
He was distrusted by his police colleagues, hunted down by Han Chen's men, rejected by his girlfriend, and hated by his friends.
Neither human nor ghost!
That being the case!
I choose to turn to the dark side!
"Ding... The 'Darkened Troop Explosion System' has been bound. Reward: The Seven Heavenly Brothers..."
With the trump card in hand,
Huo Wenyao decided to flip the table!
First, eliminate Han Chen and seize all his assets.
Then, they summoned various ruthless gangs: the doctor's gang, Hong Jipeng's gang, the Wang Jianjun brothers, and Qiu Gang'ao's gang.
He overthrew Hung Hing, pushed down Tung Sing, destroyed Wo Luen Shing, and step by step built his own underground dynasty.

Then it ventured into the business world, destroying HSBC and Jardine Matheson, and crushing British tycoons such as Li Ka-shing, becoming a capital giant with influence radiating throughout Asia.
