The Age of Energy

The Kingdom of Science begins working on the complex components needed to build Senku’s cell phone, a critical tool for the upcoming war. However, producing thin gold wire by hand proves to be an exhausting and inefficient challenge. To overcome this obstacle, Chrome and the master craftsman Kaseki come up with a revolutionary idea—the invention of a water wheel. This breakthrough dramatically increases productivity, marking the dawn of a new age powered by energy, machinery, and scientific innovation in the stone world.
