After a Deranged Villain Got His Hooks into Her, She Ascended Through Good Deeds

(Villainess cultivator, female lead, System, no romance. The pitch has been approved, so please add to your collection!) Elite teacher Xi Qingyue wakes up to find herself the master of five great fiends: the Demon Venerable of the Blood Yin Hall. Each of her five disciples is crazier than the last! Their evil scores are higher than one another's! All they think about every day is killing. [Congratulations, Host, you have bound to the Merit System of Moral Guidance. The day everyone's evil score reaches zero will be the day you ascend.] Xi Qingyue: Isn't this exactly my area of expertise? From that day on, the Blood Yin Hall's ways changed: Bloodhand Demon Li Xuan gets up early every day to stand on the mountaintop and recite the Rules for Disciples... The Thousand-Faced Poison Master spends every day figuring out how to make calming tea... At first, the five disciples suffered terribly. Making fiends do good deeds? Had their Demon Venerable been possessed? Later, they followed their master step by step to the peak of the cultivation world, earning the respect of other sects as well. The five disciples changed completely. Wherever they went, they told everyone: If you're going to cultivate, follow your master and walk the righteous path!
