Villain's Path: My Senior Sister Replenishes My Yang!

Transmigrated into a fantasy world as the villain, I'm immediately rescued by my gorgeous senior sister—who proceeds to slap me across the face! The protagonist worships me, destiny itself hates me, and I couldn't be more thrilled. As a true disciple from an immortal sect in the upper realm, I'm here for worldly experience. Crushing some so-called 'Child of Destiny'? Please. With my background and a senior sister who knows exactly how to 'replenish my yang,' this is going to be fun.
