After a dramatic upheaval on her wedding day, Sheng Niannian, the legitimate daughter of a general's household, leaves for a distant land with her triplets. Over the next five years, she studies medicine diligently and remains devoted to helping others. When she returns to the capital, she seeks no revenge or old grudges, asking only for a divorce and the safety of her children. At the birthday banquet, she keeps her composure in a crisis, arranges shattered stones to form the words 'May You Live Ten Thousand Years,' saves the Sixth Prince's Consort, and earns a jade token granting immunity from execution. She also outsmarts the General's household's schemes and protects her birth mother. Each of the three children displays their own talents, becoming their mother's strongest support. Through their time fighting side by side, Prince Han Ye Wuyuan finally sees the truth and transforms from an obsessive man into her protector. United as husband and wife, they clear the old case, while Sheng Niannian uses her medical skills and benevolent heart to bring blessings to the capital and build a kingdom of her own.
