During the Dajing Dynasty, the moon was as cold as water and people's hearts were like frost. Shen Qingci was once the daughter of the prime minister who was famous in Beijing. Once her family fell into decline and her father and brother were unjustly imprisoned, she took off her clothes and hid in Yueliang Town, a water town in the south of the Yangtze River. She made a profession of medicine and guarded a lone lamp, waiting for the day when her injustice would be over. She thought that in this life, she would only have the fragrance of medicine as her companion and the moonlight as her neighbor, but she never thought that an unexpected medical visit would bring her into Xiao Jue's world.
