In the misty Jiangnan of the Dayin Dynasty, a heavy rain closely intertwined the fates of Shen Yunshao, the legitimate daughter of the down-and-out Hou Mansion, and Xiao Jinyuan, the prince of Zhenbei. She healed him and detoxified him, but he mistakenly thought she was the daughter of his enemy but couldn't bear to do it; he gave her half a piece of residual jade, and she left behind a handkerchief embroidered with hibiscus flowers - no one expected that this would be the beginning of entanglements in troubled times.
When Shen Yunshao was forced to marry into the prince's palace on behalf of his sister, the old prince died suddenly on their wedding night, and the two were forced to work together to solve a series of unsolved cases. From the wedding hall to the mourning hall, from the harmonious singing of the piano and the piano to the tense situation, they tested, suspected, fell in love and killed each other in the whirlpool of power and intrigue. She was shocked to realize that there was an ancient poison dormant in his body, and he discovered that the scar on her wrist hid a shocking secret; when she faked her death and escaped and sneaked into the enemy's hinterland, he was missing by the deep sea and could only scream her name in the beacon fire.
As the identity of the former princess was exposed, the iron hooves of the Republic of China Army shattered the peaceful life. When Shen Yunshao was faced with the choice between his parents and his country, Xiao Jinyuan swore that "my territory is only where my wife and children are." Little did he know that he had already been involved in a larger chess game - the late emperor's edict revealed the lie of centuries-old grudges, the contest between the conservatives and the reform parties swept the world, and the alien coalition forces took advantage of the opportunity. Their children have been instilled with the belief in revenge since childhood, and youth instigation turns out to be the key to stabilizing the situation.
From the water towns in the south of the Yangtze River to the grasslands of Saibei, from the Maritime Silk Road to foreign countries, they worked to mediate during the locust plague, depended on each other for life and death during the Hegong Uprising, and took action to break the vassal rebellion. Medical skills and martial arts are intertwined, gentleness and iron-blood collide. When the legend of the Phoenix reborn from the ashes shines into reality, can they temper their sincerity in the ashes of fate?
