Carl swam deeper as he strengthened his shield to suit his surroundings. He was around thirty meters under the sea and found it cold. He hadn't learned to deal with it yet. "Miku, I feel cold. Is there a way to warm it up?" he asked. The only way he knew was to use a lighter. However, it wouldn't work in water, would it?
"There are tools for it, right?" Miku asked him back.
He thought. What tools could be used?
Then he gave a shake. "What's that?" Wrong question. He should have known better about that than her.
She shrugged because she really didn't know. She had only foreguessed. "Maybe something quick to boil water like a kettle at home? Isn't there a similar tool to warm up a larger amount of water?"
He thought again. He felt like there was such a tool. He had never seen it in person but had felt it. That was for warming the pool. "I think there is, but I'm not sure we can use it in the ocean. There's too much water to warm up."
