Villain System: Let the Young and Naïve Duchess of the Cang Court Principality, Sylvia, Experience the Betrayal of Her Loved Ones, and Achieve Transformation and RebirthTransmigrating into a Western fantasy world centered around beast taming, Xia Ya stared at the beginner mission in front of him, lost in thought.Sylvia—the legendary “Silver Witch of Cang” recorded in history—had already ascended to legend status five hundred years ago.

Not long after my exile, an evil god descended upon the royal capital, annihilating all life.So… my brother did all of that… to save me?
