After Reclaiming My Roots, I Join My Fake Heiress Sister in Tearing Through the Marquis's Estate

The day I left Medicine King Valley, I was taken to the Mighty Marquis Residence, where I learned I was the marquis's eldest daughter, switched at birth by mistake.

Mother hugged me tightly, blaming herself for failing to discover the truth all these years.

Father waved a hand and gifted me jewelry and fine clothes worth a fortune.

My brother thumped his chest and vowed to dote on me until every noble young lady in the capital envied me.

Only the eldest daughter who had taken my place for fifteen years glared at me with hostility.

"I'm telling you, there will only ever be one eldest daughter in this residence, and it's me!"

I had no desire to argue with her, but a string of comments suddenly appeared before my eyes.

[Here we go! As long as the real daughter gives her a welcome gift, the male lead and his parents' plan to turn the two girls against each other will succeed.]

[Next, they'll compete for favor. One will drain her heart's blood and become a medicine human, suffering a fate worse than death. The other will be poisoned with an aphrodisiac and seduce the Third Prince, who will fall gravely ill, paving the way for the male lead's career.]

[Too bad that once the male lead has made a name for himself, both sisters will be beyond saving because their bodies have been damaged too badly. In the end, they'll be thrown out onto the streets and freeze to death.]

The hand clutching the welcome gift for the eldest daughter suddenly grew hot.
