"Finally got out of the Dark River." Catherine stretched her waist with a sigh of relief, sitting on the ground and taking off her waterproof pants and boots. "My legs are numb from the cold. Why is the water in the cave so chilly?"
"This river flows out from the Frozen Lake in the Frozen Hell. That's the coldest place in the lower caves. According to our route, our final destination is there," Mr. Pannis's voice was still a bit unnatural after the silence just now. "It's a troublesome place, very troublesome."
"What's so troublesome about it?" Catherine asked, puzzled. "Isn't it just cold?"
"It's not just the cold," Pannis frowned. "Let's leave it at that. After we find them, we're still planning on exploring the Frost Realm first. If we can't find them there, we'll consider other options."
"You're the expert, you call the shots," Catherine reiterated her earlier statement.
