I Picked Up a Disciple Who's a Black Lotus

Blurb: Fu Yu found a pitiful child in the human world, took him in as her disciple, cleansed him of the filth covering him, and patiently guided him. From a young age, Yan Zimo was passed from one buyer to another, wandering from place to place and seeing the world's ugliness firsthand. Fu Yu's arrival was a little flower blossoming in the muddy mire of his life. To protect his little flower, he kept his violent nature in check and worked hard to cultivate. In just over a century, he became the most gifted disciple of the Yongqing Sect. Everyone in the sect thought of Yan Zimo as a bright, aloof figure, like the moon in the sky or a snow lotus in a pond. Only he knew how dark and twisted he was, and that his feelings for his master could never see the light of day. When he learned that his master was marrying into Qingqiu, demonic energy flooded the Yongqing Sect and black clouds churned overhead. Yan Zimo transformed into a Blood Demon and abducted her. Theme: Positive feelings can bring uplifting, positive energy.
