Zhao Heng, the emperor of the Great Zhou Dynasty, was reborn into a dangerous situation where he was ignored by the princes and surrounded by powerful ministers. In the name of a "weak lord", he secretly worked step by step, first using Wen Boheng's corruption as a sword to cut through the iron curtain of the court; then borrowing Pei Zhao's loyalty to reshape the imperial army; and using Xie Xuanying's navy to break the siege of Xiao Chengji in the north. Empress Shen Zhaorong struggles with the guilt of her past life between her family and her husband. Every choice she makes rewrites history. Zhao Heng has gone from being a puppet in the palace to playing chess in the world. Every plot and every battle is the beginning of him demanding his life from his old enemy. The princes had not yet noticed that the young emperor with low eyebrows and obedient eyes had already sharpened the butcher's knife.
