A complete team of modern doomsday underground ark survivors (including engineers, agriculturists, tactical commanders, psychologists, etc.), At the moment when the ark ran out of energy, collectively traveled to a low-magic fairy world where the aura had just been revived and the civilization was in feudal ancient times. What they faced was not a high-level fairyland, but a troubled world that was not much better than the ruins of Doomsday, full of wild monsters and ignorant sects. The mission of the protagonist group is: to use the last remaining "civilization fire" and "scientific methodology" to rebuild the glory of mankind in this new world, and to uncover the ultimate secret of why the two worlds are connected.
