In the village, Kaseki finished building a wheel. Senku creates blueprints for a steam engine vehicle. Using beeswax, Senku creates a mold for pistons and other parts. At Tsukasa's headquarters, Chrome declares to teach Tsukasa how amazing science is. Hyoga dangles Chrome at the waterfall while Tsukasa interrogates him. Tsukasa wants Chrome to betray Senku and the village in exchange for Senku's head and the village's safety.
