Xin Qiji was reborn as Huo Qubing's twin brother. His biggest bargaining chip was his macroscopic understanding of the "future" historical direction from the Southern Song Dynasty, as well as Xin Qiji's lifelong literary, Taoist, and military strategies, political wisdom, and unfulfilled ambition. However, the price of failure he faces is twofold: if he cannot change Huo Qubing's fate of dying young, he will once again lose the sharp blade to protect China, and repeat the mistake of his previous life of "serving the country without wanting to die on the battlefield"; if he cannot gain a foothold in the turbulent court and battlefield, he himself will be swallowed up by the torrent of history and conspiracies like his previous life, and completely annihilated with double regrets.
