The Science Team embarks to rescue Chrome as Senku is unable to persuade the elderly villagers to remain behind. They sets up camp near a cliff, Kohaku keeps watch, while Suika moves ahead to scout. Senku decides to modify the Steam-Gorilla and make it a tank. He makes Paper-Shields to armor the Steam-Gorilla. Kinro expresses disbelief at the strength of the Paper-Shield, to test it Senku asks him to attack the shield with his spear, however Kinro's spear breaks when he attacks the shield. Senku finishes the Steam-Gorilla Tank. Tsukasa builds anti-vehicle traps, wary of Senku possibly building a vehicle.
