Wen Shutiao is the true daughter of the Yongning Marquis's household, who was lost and raised elsewhere.
On the day she was born, her wet nurse, driven by selfish motives, switched her with her own daughter. The impostor, Wen Shuyue, took her place and lived her life.
When the truth came out, Wen Shutiao was brought back to the marquis's household.
The family looked down on her as a bumpkin from the countryside and treated her with cold disdain.
The Yongning Marquis's household had long ago arranged her marriage to Xie Jue, the Second Prince.
But Xie Jue's mother was only a palace maid, and Wen Shuyue had no intention of marrying him.
To escape the match, she secretly schemed to force Wen Shutiao to take her place.
Under the marquis household's threats, Wen Shutiao was forced to agree to the substitution.
Swayed by Xie Jue's honeyed words and desperate to prove herself, she poured her heart and soul into helping him seize the throne, personally placing him in the position of Crown Prince.
But in the end, Xie Jue loved Wen Shuyue.
The pair conspired together and ended Wen Shutiao's life with a cup of poison.
Reborn, she bound herself to a revenge System and vowed to make the scoundrel and the wicked woman pay. Her revenge began in earnest.
She knew she couldn't get her revenge alone. The emperor, Xie Lin, had ruled for many years and was known for his cold nature. He became a blade in her hands.
The delicate young woman threw herself straight into the emperor's arms. She advanced step by step, deliberately tempting him.
The emperor, who had never been interested in women, fell for her. He willingly entered her game and was ready to give everything to fulfill her wishes.
With the emperor's help, Wen Shutiao made Wen Shuyue and Xie Jue pay for their blood debts.
She seduced the emperor into taking the throne, ascended the phoenix throne, and became empress of the realm.
