The Dajing Dynasty has been peaceful for a hundred years, and the imperial power has gradually declined. The queen and her brother, the prime minister, are in charge of half of the court. The Li family, the minister of the Ministry of Industry, was a prominent family for a century. Li Xian was upright throughout his life, but he was regarded as a thorn in the side of the prime minister. He falsely conveyed imperial decrees, falsely accused him of corruption, and even had his family exterminated. From then on, he controlled the dynasty, had private soldiers, and became rich enough to rival the country;. General Han and Li Xian were close friends. They were called back to Beijing to guard the border. It was very sad to see their former close friends being exterminated. From then on, a secret investigation into the matter began. Eighteen years later, General Han's son (Han Jingan) became famous at a young age and was granted the title of Marquis Jingyuan. He was in charge of the military power in northern Xinjiang and was the royal family's sharp weapon to check and balance the family. Above the court, the Han and Du tribes were fighting openly and secretly, and the undercurrent was surging. The male protagonist was betrayed by his comrades on the battlefield, was injured and fled to a mountain, where he was rescued by the female protagonist. Then began the two-way redemption of various misunderstandings.
