Shen Qingci, who in his previous life assisted a scumbag to ascend the throne but was squeezed out of his worth and died tragically, was reborn on the sedan chair where he was forced to marry the regent. He took the initiative to knock on the door of Xiao Yan, the cruel wife of his wife, and used the antidote spell as a bargaining chip to make a deal - she helped him seize the world, and he protected her and took power for revenge. In this transactional marriage, the heroine who is sober and engaged in career gradually develops a true love with the powerful minister, but the heroine always insists that "what I want is power and freedom, not competition for the favor of the wife."
