Chapter 518: Entombed In Silence

Yui nervously approached the scary demoness whose name struck terror for the older generation of Hunters.

This demoness was so tall, and her aura was intimidating enough to make Yui feel as if she might die if she got too close. If her Master managed to enslave a demoness like this, just how terrifyingly strong must he be?

With a cautious yet determined demeanor, Yui gently touched the metal buttons adorning the wall and began her explanation, "These buttons," she said, her soft voice steady despite her nerves, "each has a specific purpose. They're labeled so that anyone can understand their function."

Rebecca, her patience already thin, flicked her wet silver locks back with a scoff, "The last time I visited this world was more than 60 years ago. But you humans seem to have devolved to make things harder than they need to be," she remarked, her voice dripping with scorn.
