Nie Yongxiao transmigrates into the tragic second son from Infernal Affairs II and awakens the “Overlord System.” Nie Kun is killed from the start, and the four top lieutenants turn against him. With his grandmaster-level Bajiquan and the aura of a future crime boss, he first puts Han Chen in his place, then uses leverage to keep the four elders in check and stabilize the Nie family's foundation. From then on, he will no longer be a gentle gentleman. He will become the new godfather who rules Hong Kong Island's underworld with an iron fist.
