After the whole family of the Zhenbei Hou Mansion was destroyed, Qin Zhao was reborn on the execution ground and returned to fifteen years ago. He no longer acts as a loyal minister, but draws on the memories of his past life to work step by step, first eliminating his enemies, and then winning people's hearts. He forms an alliance with the swordsman genius Shen Qingwu, subdues the rebel general Xiao Wujiu, deals with the northern lord Yan Chiyu, and even competes with Yue Jianxue in the maelstrom of intrigue. With all the old grudges settled, he pointed his sword towards the sky, vowing to overthrow the decadent dynasty and make the world a river of blood. However, the secret of rebirth, the identity of the orphan from the previous dynasty, and the chess game played by the mysterious old man Xuan Yi all make this road to dominance increasingly complicated and confusing.
