My Empress Apprentice Is Becoming Evil

The once abused little disciple suddenly finds that her master has become gentler, stronger, and increasingly acts tough while being soft-hearted towards her... Su Changge: "Damn system, I don't want to be a scumbag villain!" System: "Born to be a scumbag, destined to be a villain!" Feng Wanqing: "What should I do if I fall in love with my master?
