William didn't know what to say, except to change the subject:
"I got this from the other world we went to, it seems its spirit power is quite concentrated and pure. This is great news! We can come here when reaching the pinnacle stage, and get endless benefits from training here."
"This…" Speaking about this shifted her attention away from what she wanted to ask, "Are you sure it's safe?"
"Nothing in this world is safe, right?" he shrugged, "As long as I'm here, we can handle it."
"What if… It just came out…" She pointed towards the hole with both hands and didn't know how to explain her thoughts.
"I hope it won't," William looked at the hole before adding, "This hole is the only thing stopping that spirit power from spreading. I've been there for hours, and so far it's so good."
"But it may leak out, and hurt lots of people right?" She interrupted him, and he couldn't refute her words.
