Five years ago, Su Jianwei, the princess of Zhaoning County, burned the military rations. She was convicted of a crime that caused harm to the country and was exiled to the far north. Five years later, she returned to the capital while lying in a coffin: "The imperial decree sentenced me to exile until death. Now that I have died once, why not come back?" The world thought that she just wanted to reverse the case and take revenge, but they didn't know that three thousand "dead soldiers" were still alive, and the poisoned food, the East Palace and the emperor's old sins were all hidden behind the fire. She used the infamous name of A and the spring lantern as a network to rescue victims, open a women's clinic, and re-examine old cases. She went from being a guilty woman in a coffin to becoming the new emperor elected by all nine states. Gu Yanci, the cold-faced young minister who once personally convicted her, will also accompany her to re-judge the world and uphold the first law of the new dynasty.
