Su Qingnan, the Sixth Prince of Great Qian, was implicated in an old family affair and came to be regarded by the outside world as the Prince of Beiliang, a good-for-nothing whose martial arts had been completely crippled. For years, he lay low in silence, secretly reorganizing Beiliang, improving people's livelihoods, recruiting talented individuals, and training elite troops, all to protect the people living along the border. As his engagement is called off and various forces begin testing him one after another, Su Qingnan gradually reveals his true strength. Leading the Beiliang army, he puts an end to border threats and recovers lost territories, rising from a disgraced prince whom everyone looks down upon to a ruler who commands the fate of the entire realm.
