The Cold-Faced Regent's Beloved Poison Doctor and Adorable Baby

In the Great Yin Dynasty, the cold and ruthless Regent Xiao Yichen wields immense power, yet suffers torment from a mysterious icy poison in his body. To preserve her sect's lineage, the Holy Maiden of the Mystic Sect, Baili Susu, crosses paths with him on a cold night of fate and gives birth to their daughter, Xiao Yao, whose soul carries the knowledge of a modern poison doctor.

Xiao Yao is exceptionally gifted from a young age. She never forgets a herb or poison she has seen, and can heal people with simple medicinal plants. To protect her from persecution by Xiao Yichen's political enemies, Baili Susu painfully sends her daughter to the prince's manor. When she first meets her father, the little girl is utterly unafraid. She not only pinpoints the source of Xiao Yichen's icy poison, but quickly wins the hearts of everyone in the manor with her mischievous antics and remarkable skill with poisons and medicine, gradually turning the cold-faced prince into a doting daughter slave.
