The eldest princess Li Yanxi was originally a chess piece placed by her father in the Zhenguo Palace to overthrow the founding family with great achievements.
In her previous life, she watched the Duke's palace being exiled and his consort heartbroken, only to realize that she had already been deeply in love; her mother died tragically, and she also died of illness in the palace.
Once she was reborn on her wedding night, she decided not to let anyone manipulate her again. She closely liaised with the Duke of the country, taught the dandy prince son-in-law strictly, copied books and punished him by kneeling, polished his character, and raised a naughty child into a peerless man.
The husband and wife teamed up to defeat the emperor's plot, save the queen mother, and support the new emperor. In the end, they gave up the imperial power and wealth and traveled the mountains and rivers hand in hand.
