The Fake Heiress Swapped Marriages and Jumped into a Pit of Fire, While Her Sister Married a Powerful Minister and Rose to the Top

Xie Ningyin is reborn inside the bridal sedan and only then learns that her younger sister has been reborn too.

In their previous life, her sister stole her marriage match, only to live as a widow, be exiled, and finally die alongside her.

In this life, her sister cries and begs to switch back to their "original" marriages, pushing Xie Ningyin into the Duke of Zhenguo's household.

The whole capital laughs at her for stealing her sister's good match, waiting to see her ignored and mocked.

Xie Ningyin looks at the devoted, protective husband before her and thinks of the fiery pit her sister is about to leap into. She smiles sweetly.

Later, her sister schemes against concubines in the inner quarters, raises an ungrateful wretch, and waits bitterly for her husband to rise to prominence.

Meanwhile, Xie Ningyin uses her medical skills to save the emperor and empress, open up trade routes, and rise to power...

Her sister screams in despair, "Why, after living another life, are you still so lucky?!"

Xie Ningyin looks down at her and replies calmly, "I've never believed in fate. I only believe in my own hands."
