The eldest princess gave birth to a daughter, who was killed by the prince's consort and an outside wife and was reborn. Neither the eldest princess nor her daughter knew that the other party was reborn. After rebirth, the eldest princess remained unmarried and stayed with her daughter for the rest of her life. The daughter was often jealous of men because of the shadow of her consort. The daughter of the eldest princess was privately the master of the Yanyun Cavalry, and the master of the "Tianji Pavilion", the largest intelligence organization in the Han Dynasty. She was the number one killer, but in front of outsiders she was arrogant, domineering, and extravagant. Little did she know that none of the men she chose survived.
