Returning to the desert island, Conan, Lana and Dr. Lao recover the flying machine Lao used to escape from Industria, but they need to return there to fix it completely. While flying to the city, they find and rescue Dyce, who was left to die in the desert for his act of rebellion. The Falco arrives and attacks, but Conan tricks the crew into crashing their plane. When another earthquake occurs, Lao begins to surmise that the Earth's crust is breaking up, heralding yet another cataclysm. Following their arrival, Conan and Dyce go to rescue the crew and retake the Barracuda, while Lao and Lana infiltrate the Triangle Tower. However, Monsley has had time to inform Lepka that Lao is back in Industria.
