"With the late emperor's passing and the crown prince's martyrdom, the bloodline of the Great Qian imperial family was extinguished. Sun Fu, the Minister of the Imperial Clan Court, examined the imperial genealogy and discovered that although Chen Yu, the son of Prince Xian, was born to a concubine, he met the criteria of 'succession to the throne by a younger brother upon the death of his elder brother.'" Following ancestral instructions, and acting on the Empress Dowager's decree, the Emperor went to Yunwu County to welcome Chen Yu as the new emperor. At this time, Chen Yu was at the lowest point in his life. He had been married into the Song family for five years, but after the death of Song Taigong, his wife, Song Ziyan, under the influence of Zhao Jingxuan, the son of the county magistrate, insisted on divorcing him, even going so far as to change the funeral into a celebration. Zhao Jingxuan repeatedly humiliated Chen Yu, not only causing a scene at the funeral but also subjecting Chen Yu and his mother to torture.
Chen Yu insisted on holding the funeral for Taigong before divorcing him, but this was misunderstood and met with disdain from Song Ziyan. Her jade bracelet was smashed, and her dignity was trampled upon. At the critical moment, Sun Fu arrived with an imperial decree, rescuing Chen Yu and his mother. At the royal banquet, Chen Yu revealed his identity and ascended the throne. Only then did Song Ziyan realize she had missed a golden opportunity and knelt down to repent. However, it was too late. Remembering his grandfather's kindness, Chen Yu didn't exterminate the Song family, but he severed all ties with Song Ziyan.
Afterwards, Chen Yu returned to his hometown to visit relatives, where he was looked down upon by the Qi Wanshan family. It wasn't until the county magistrate arrived that everyone learned of his imperial identity. Upon returning to the capital, Chen Yu faced a rebellion by Shen Shuo, the son of the prime minister. Fortunately, thanks to the loyal protection of his personal guard, Zhuozhuo, he escaped danger. After Shen Shuo's defeat, Chen Yu repaid evil with kindness, demonstrating the magnanimity of an emperor. At the end of the story, Song Ziyan, reduced to a beggar, encountered the newly enthroned Chen Yu on the street, filled with remorse. The drama concludes with her shock and regret. The story ends with Chen Yu firmly seated on the throne, ushering in a golden age, showcasing his transformation from a lowly son-in-law to a ruthless emperor.
