Once demoted as a slave, Shen Zhiyi heard an edict that did not belong to this era in the woodshed on a cold night - "In the 23rd year of Yongchang, Prince Xiao Jingheng usurped the throne and ascended the throne.

In order to change her destiny, she approached the cold-faced prince with a humble body, and worked step by step, pretending to be obedient while secretly arranging plans.
