Jiang Buwan returned to the Jiang family as a "discarded daughter" and secretly laid out plans as the divine doctor "Sadan". She established her authority in the family struggle, revealed her identity when her father was critically ill, and used surgery as a condition to gradually seize family assets. Assistant Lu Jinhang regained his memory and turned out to be the master of the Dark Empire, "Lu Xifa". After experiencing a trust crisis, the two joined hands. Jiang Buwan settled accounts with her stepmother and stepsister, took control of the Jiang family; Lu Jinhang regained control of Asian forces. They jointly fought against the behind-the-scenes organization "Oracle", exposed the truth about his right hand being crippled back then, and finally destroyed the organization. After the dust settled, the two broke family conventions and embarked on a new journey hand in hand.
