After Earth's destruction, three survivors crash into a world of immortal cultivators. Their instruments reveal "true qi" is just ionized helium-3—so they beat cultivators with an electromagnet, wire, and physics textbook. Spirit stones become perfect fuel for their mobile base, and science seizes control of the cultivation world.
