Enslaved By My Ex-Boyfriend In An Isekai Hellscape

Kien: "Hi, I died and went to hell, so I decided to take you along with me."

When Liu Xuelan broke up with her high school online boyfriend and went to study abroad, she never imagined that she'd be reunited with him under such unpleasant circumstances six years later. Somehow, the bastard had gotten himself killed and sent to hell, which was filled with demons trying to claw their way to the top of the Underworld in a vicious dog-eat-dog world.

Kien: "Also, there's a sexual cultivation system, so bear with me if I *use* you to level up."

Xuelan: "..."

Kien: "There honestly wasn't really anyone else I wanted to fuck, so I picked you."

Note: This story is total trash and I'm embarrassed to have even come up with it. Warning: Enormous non-con/dub-con alert, not for those who are faint of heart. It’s very dark, inconsistent, and angsty. I'm not very good at writing smut. I'm not very good at plot either...
