Waterways

It seemed like an absurd suggestion. Kane did not even bother replying. His expressions fully conveyed the sheer magnitude of how unimpressed he was. "Explore the rest of the dungeon first before mining a floor that we just cleared, have you lost your mind?"

"Hear me out," Rui placated him. "The water isn't going to stick around for too long, it will eventually be absorbed into the bedrock of the dungeon. I told you the benefits of exploring the dungeon while the water was still there, right?"

Kane nodded. "Tunnels systems that don't really lead anywhere except for eventual dead-ends will be blocked off, while tunnel systems that lead to dungeon floors will be open because the water will be drained into the dungeon floors, rather than being blocked off inside the tunnel."

"Exactly," Rui grinned. "So basically, the water is the best exploration team that we could possibly ask for."
