Bab 588: 588. Rush To The Mines

Walker looked toward the rooftops where he began to see dwarves here and there. They were setting up tripods on the roofs and connecting them to the pipes. He had no idea what was happening until he felt the surge of water elemental mana. 

He began to feel drops of water on his face almost as if it was raining within a place without a sky. It was a wonder to him until he realized that that the tripods were a form of watering device. The water from the pipes was being sprayed  to soak massive areas with water as if it was really training. 

"We only do this when we are on higher volume periods and the heat causes things to melt or catch fire. I never planned for this system to be used t defeat slimes. Let alone, a species I have yet to see in my life." The king of the middle was still bragging making Walker worry even more.
