After listening to all the plans, one dwarf said, "Lord. what. about. Other. Zone."
He shook his head, "Not sure about zone 2 and 3, but zone 1 and 0 must need to have an arena." He still was not sure about where to place elite-grade snakes and left those planning after the experiment.
All 4 nodded and 2nd one asked, "Lord. there. are. Many. ways. Make. Arenas."
"Really?" Grave looked at them in confusion and asked, "Tell me a few of them." Though he came with the arena he did not think too deeply about the ground construction. He already had enough on his plate, so he did not give them any crude construction design.
"Lord. we. can. make. one. big. arena. where. everyone. come. to. watch. or."
"We. can. make. multiple. small. arena. say in poison. forest. we. can. make. 20 arena, 1 for. each. species."
