I couldn't open the Channel with these three here; I had to create a Mana concealment at all costs. I decided to put off the summons for a while and listen to their story.
"First of all, thank you for your help."
I nodded without replying. These two were brought here to monitor and gather information, and a lot of my metallic materials were consumed in the process. Even though they were quite troublesome to buy, fill, and make, they weren't expensive materials; I should think of it as an opportunity cost. Instead of saying anything, I silently waited for Yusu to speak.
"I have heard about the kind of arrangements you have placed in the crack in space. Not only this world but also the world across the crack; you created a sealed barrier, right?"
"Yes."
