Undercurrents surged in the age of martial virtue. Qin Wen, the legitimate son of the general, was in a high position at the age of twenty-one. He was granted the title of Border Marquis and was in charge of 200,000 border army cavalry. His father Qin Hanxuan was a Taiwei, and the Qin family was extremely powerful and had no title, which aroused the fear of many emperors, civil servants and clans. The royal family repeatedly tried to restrain the princess by marrying him, but the Qin family flatly rejected them.
Qin Wen was ordered to go south to investigate the case and was assassinated. He was injured and fled to the south of the Yangtze River. He unexpectedly met Shen Bailin, the daughter of a merchant. She was caught in a dispute in the house, with a gentle and tenacious character and a pure heart that was not tainted by intrigues. She suddenly broke into Qin Wen's life full of killing and plotting.
The imperial power was tightening step by step, turmoil arose in the court, Emperor Wu died suddenly, and the new emperor ascended the throne and the power struggle resumed. Their identities are separated by clouds and mud, and the road ahead is full of dangers. Qin Wen is devoted to each other in the whirlpool of power, and Shen Bailin accompanies him with her intelligence and character. The two cross the family gap, fight hand in hand against the wind and rain, and maintain a deep love that is not favored by the world in the palace of dynasty.
