Amidst the chaos of war, a hundred-year-old elder Su Mu and his little granddaughter depended on each other.

To protect her, Su Mu stepped forward to enlist in her place, enduring endless mockery from others, and unexpectedly awakened the God of War system. He lifted a giant cauldron to establish his might, fought bravely against enemies on the battlefield, and remained razor-sharp even in the vanguard camp. Targeted and framed everywhere by garrison commander Xu Shigui, Su Mu turned the tables by playing along, joining forces with various factions to crush the Northern Di army. The centenarian veteran shed blood to protect his country and family, breaking through all obstacles along the way. His monumental military exploits shocked the imperial court and military, ultimately making him the God of War of the Northern Frontier.
