She should have been a phoenix among the branches, but she was switched at birth and made into a servant girl. She loyally served the young lady, only to be betrayed by her in return. Fortunately, Heaven has eyes: reborn in a new life, she rolls up her sleeves and vows to bring the young lady down. But... why on earth has that wicked young lady been reborn with memories of her past life too? Heaven, you can't keep making things this difficult! It wasn't enough to let the young lady steal her place. Now she wants to fight her for their senior fellow disciple, too? Does she really think she's a pushover? She's a professionally trained assassin, after all. In this life, she'll surround the enemy with every move and checkmate them with her final play. Who else could do it but her?!
