Military engineer Li Mo transmigrates into the body of a dying beggar in ancient times and binds himself to the “Civilization Heritage System.” With technological knowledge far beyond his era, he starts by making improved tools, then gradually smelts fine steel, makes gunpowder, and develops firearms. Amid the flames of war, he maneuvers between the county magistrate, the mysterious organization Shadow Pavilion, and various other factions, using technology to leverage power and build an armed force of his own. From the slums to the battlefield, from workshop technician to regional warlord, Li Mo follows a road paved with steel and fire, eventually claiming the realm for himself. Along the way, his fate becomes intertwined with those of three women, each with her own character: the gentle yet resilient Lin Wan'er, the clever and mysterious Su Qingyue, and the bold, decisive Qin Hongyu, who appears later. Together, they will write a legend.
