The system of the Ming Dynasty was strict, and the Chu family had been officials for generations. Chu Yunyan's father was a second-rank official in the imperial court, but he repeatedly criticized Long Yan and angered Long Yan. In addition, he was framed by traitors and was killed by nine tribes. Chu's father secretly sent a pair of children out of the house so that his sister Yunyan and his brother Xuanyun could survive, but unexpectedly they got lost along the way and each lived a wandering life. After the eldest princess Yingluo learned about it, she secretly ordered someone to find Yunyan and come to the palace to become a maid. A few years later, Yunyan met King Xin, and gradually became the queen of the dynasty, finally avenging her father's injustice. When the siblings recognized each other, it was already a time of great change. Xuan Yun recognized Hu as his father, eventually forcing himself to a point of no return.
