One day, she transmigrates into her own funeral, where her scumbag ex is showing off his affair with his shameless mistress in her mourning hall.
To prove his worth as a benevolent ruler, the emperor promises that whoever marries her will become the crown prince.
The Hua family has served the throne loyally for generations. Knowing that Great Yan has no one to secure its future, they decide the original owner should marry the future crown prince, assist him, and protect Great Yan.
But the one who transmigrated is a woman of the modern age. She won't be threatened by worldly matters or crushed by a sense of duty.
Instead, she takes another path, striking a bargain with the imperial uncle, a powerful figure who stands outside the rules and holds sway over the court.
Little does she know that the cold, unfeeling imperial uncle has already prepared to take all of Great Yan down with him.
But with her in Great Yan, losing it suddenly seems a shame.
[I hear the Hua family's legitimate daughter is widely learned and capable of assisting in government. If you help me ascend the throne, I will grant you a lifetime of peace.]
She thinks his protection means restoring the Duke's residence to its former glory, but she never expects to be coaxed into becoming the only woman in Great Yan's imperial harem.
[My heirs are a matter of national importance. The empress must work hard, day and night.]
