On a quest to understand humanity, Bai Suzhen starts off by challenging the expertise of physician Xu Xian but finds a rival named Qing ready for her.

After Bai ponders an intervention to heal a sick mother, a noble decision by Xu captures her attention.

Chaos erupts at the Lantern Festival, forcing Bai to defy the heavens; fighting monk Fahai finds out why the city's children are missing.

With an assist from an old friend named Jingsong, Bai attempts to find the missing children and learns the truth about the powerful culprit.

Bai fights the powerful culprit with a crew of former adversaries and later tests Xu's integrity when she gets suspicious of the people around him.

At Xu's family dinner, Bai must act as a mere mortal but faces friction from his longtime admirer, Jin Ruyi.
