When she held up the foreign object, Kaiba nodded. "Sounds like something straight out of an RPG," but at least it looked as if it might be rooted in science and technology unlike- oh say- a bag of holding in tabletop gaming. "I wouldn't bother potentially ruining it, no. None of my equipment is working either- and I have dissembled and reassembled it." At least with the extensive work he'd put into his duel disk he was sure there had been no mistakes in the attempted repair process. As for the portion she left unvoiced, he would have scoffed at the notion of the Earth being no more- unless. Unless Yugi had ended up losing that last duel, though even then he was dubious that Dartz could actually restructure the world.

It was clear from the position she took, that she was truly giving the plans a thorough inspection.

"Considering we only just regained the ability to utilize fire, it's a tall order to expect a more complicated process to succeed." Though it would be more durable than the suggested material on his sheets. After a brief pause- he realized just how defeatist his words had sounded and he didn't like it one bit. Had he been here so long that he was going to allow this place to determine how and in what manner he proceeded? Without even trying?

"Heh- it might be worth a shot at that."
