Su Yu, the finest special forces king in twenty-first-century Huaxia, sacrifices himself to protect his comrades during a decapitation strike and transmigrates to the Jiajing era of the Ming dynasty. Armed with the most powerful Support System, he starts from nothing and steadily builds his own power. Through a series of twists of fate, Hu Zongxian, Yan Song, Xu Jie, and others all help him grow stronger. Alongside his three sworn brothers, Su Yu wages war against Japanese pirates in the east and repels the Jianzhou Jurchens in the north. Wherever his blades strike, Ming officials prevail; wherever his horses ride, Ming territory expands. Step by step, he rises to greatness and ultimately ushers in a golden age for Huaxia under the Ming dynasty.
