Ye Nian, the legitimate daughter of the Ye family, lived with her family in Jade City on the border since she was a child. She was able to carry a gun on the battlefield at the age of fifteen and made great military exploits. When she returned to Beijing to report on her duties, the emperor granted marriage to the Ye family in order for his beloved son to successfully ascend the throne. Ye Nian married Nangong Han, whom he had never met before. On the day of the wedding, Ye Nian discovered that Nangong Han was his brother's friend. Later, Nangong Han ascended to the position of prince as he wished, but he did not expect that the day he was granted the title was the day when the entire Ye family was exterminated. The blood of the Ye family paved a beautiful road for him. Ye Nian fled back to Jade City, but died halfway, in Nangong Han's arms. He thought that when he reached the top, he would be able to protect his beloved, but he did not expect that she would die in his arms.
Nangong Han accidentally returned to the past and vowed to rewrite the ending.
