Six years later, when Su Youqing took her daughter, Su Xiaoxiao, to the hospital for a check-up, Shen Mu discovered that Su Xiaoxiao had characteristics of the genetic traits in Song Jin's family. Shen Mu then informed Song Jin about it. When the entire clan of the Song family learned that Song Jin had a daughter, they were overjoyed. In particular, Song Jin's grandfather immediately ordered him to retrieve his great-granddaughter as soon as possible. From then on, Song Jin embarked on the journey of searching for his daughter.
