Chen Yu, who had been a son-in-law for five years, was forced by the Song family to sign a divorce letter so that Song Rushuang, the daughter of the Song family, could remarry Liu Yuan, the son of the county magistrate. Faced with all kinds of humiliation from the Song family and Liu Yuan's deliberate attempts to make things difficult, Chen Yu calmly signed the contract. At this moment, Zhengsun Bo of Daqianzong arrived with the heavily armored imperial guards, revealing that Chen Yu was the son of Prince Xian and the sole heir to the royal family, and was ordered to welcome him back to the capital to ascend the throne. Chen Yu tore up the letter of divorce in public, threw down a copper coin to end his five-year relationship as a coolie, and left resolutely amid the panic and regret of the Song family. He did not go directly to the palace, but decided to go back to Xianwang Palace to retrieve the relics of his late mother. With the departure of the new emperor, the power and destiny of the Daqian Dynasty ushered in a dramatic turn.
