In her previous life, Shen Heng was killed by Xiao Xuance himself, and her entire family was wiped out; in this life, she married into the Zhenbei Prince's Palace and became the stepmother of six-year-old Xiao Xuance. Ding - she set three tasks for herself: first, to find out the ghost in the palace; second, to prevent Xiao Xuance from going dark; third, to raise this future mad dog into a good cub who only recognizes her. She taught him how to recognize people, forced him to eat, made him kneel in the ancestral hall, and was the first to protect him when he was beaten. Xiao Xuance gritted his teeth at first: "I don't want you to worry about it." Then he grabbed her sleeve and said, "Mom, don't want me." Shen Heng thought she was just using him to break the situation, but when the sword fell, she still blocked him without hesitation. The king of Zhenbei, Xiao Cheng, looked at the young and old, and his eyes deepened: "Shen Heng, are you protecting him, or are you saving yourself?" After the old secret letter from the palace was revealed, she realized that the knife that killed her in the previous life was never in Xiao Xuance's hands.
