Xu Chengan, the legitimate prince of Yongsui Kingdom, was resurrected five years after he died in battle, while Ling Shushu, the righteous princess of Yuanzhao Kingdom, was burdened with the blood debt of two generations: her mother, Song Lingyue, was abducted by the late Emperor Yongsui to be the substitute for the drowned princess, which led to the entire Song family being executed; her adoptive father, Ling Zhengguo, was framed by a traitor and his family was ruined. When the two met in Taoyuan, their scarred souls redeemed each other, but they were separated again due to the rebel pursuit and Shu Shu's postpartum amnesia.
Five years later, Yongsui used military force to force Yuan Zhao to marry his daughter. Ling Shushu married into an enemy country, but met the "late" Xu Chengan again in the court - he had become a cold-faced powerful minister, but she was the princess of the enemy country. The memory of the past is blurry, but fate is entangled: Xu Chengan was falsely accused and imprisoned, Shushu ran to save him, but was repeatedly misunderstood due to the conspiracy of concentric poison and identity exchange. On the way to escape, she met her mother's old friend Ji Wuxia, and accidentally found her biological son Nian'an, and the memory fragments gradually pieced together.
Xu Cheng'an raised troops to clear the emperor's side, eradicated the traitors and traitors with iron-blooded means, and set the record straight for the Song and Ling mansions. On the day he ascended the throne, the concentric Gu turned into a testimony of sincere mutual understanding. He held her hand and pointed to the new grave and new life outside the palace wall: "You took back this country for me; I owe you the rest of my life."
