The Fairy Fell to Demonic Corruption, Only to Replenish My Magic

I'm Hao Xiu.

A menial disciple of a sect, a passing character in a novel.

But I accidentally stumbled upon the Holy Maiden cultivating demonic arts. She set her sights on me, and I was brutally "ravaged"!

"Hao Xiu, I'm the Holy Maiden of the sect! Cultivating with me is a blessing you couldn't earn in several lifetimes!"

By "blessing," do you mean becoming your cauldron and having you drain me of every shred of my dignity as a man?
