"The twelfth floor is the current frontier of floors," Rui told him. "We're going to clear it."

"If it's the current frontier of floors, then that probably means that it's going to take quite some time to harvest all those organic and mineral ores, right?" Kane asked.

"Right," Rui nodded. "Your stealth is going to be quite necessary to keep our identities hidden."

Kane's eyes widened as a decapitated serpent collapsed to the ground, still slithering while its head rolled away.

"Careful, stay away from the head, it's still alive and will bite anything that goes near it," Rui warned him, while carefully avoiding the snake. "The head can survive for days after its decapitation, and its venom is still extremely potent. Neither of us will survive a single bite."
