[Rebirth + Tycoon System + Urban Fantasy + Underworld + Satisfying Read] Bai Qi, the God of War who slaughtered his way through the Warring States era, was sentenced to death at Duyou. Now he is reborn as Zhang Jin, an 18-year-old orphan on the verge of death in a modern slum, and gets caught in a gang shootout from the start. Using the military strategies of the Warring States era, he unites scattered street fighters and employs tactics like “besiege a point to draw in reinforcements” and “win hearts and minds first” to gradually absorb the underground factions and establish the disciplined Wuan Hall. Faced with a siege by financial oligarchs and an invasion by international gangs, he brings the battlefield formations of the cold-weapon era into modern business wars and street fights, turning the underworld upside down. In the end, he becomes the underground warlord who holds all power in his hands, yet he never abandons his commitment to protecting the people or crosses the line when it comes to his country.
