I Guarded the Demon Prison for Ten Thousand Years, and Wrote a Guide to Rating Demonesses

In a fantasy world, humans and demons are at war, and chaos reigns.

Young Lu Feng inherits his sect's mission and guards the Demon Prison alone, facing countless terrifying demon women with next to no chance of survival.

Luckily, he awakens the System That Lets Demon Women Help Me Cultivate. By writing guides to evaluating demon women, he can continually earn rewards and grow stronger!

"Completed an evaluation of a fox girl. Reward: cultivation technique, Nine Yang Divine Skill!"

"Completed an evaluation of a butterfly demon. Reward: sword technique, Firmament Divine Sword!"

"Completed an evaluation of a rose flower demon. Reward: movement technique, Wind God's Feet!"

Ten thousand years later, countless powerful demon women gather obediently around Lu Feng, reminiscing about the past with sweet smiles.

"I didn't want to give in, but he wrote an evaluation of me, you know."

"Hmph, it's not like I wanted to reach the pinnacle or anything."

"I meant to get the better of him, but who knew he would be so strong?"
