Global Inundation: I Built a City

The apocalypse descends, the world is submerged, and less than one-tenth of human civilization remains. Under the scorching sun, Hu You is tied to a kayak, about to be turned into cured meat by others. On the eve of the deluge, he is reborn. He awakens the "Apocalypse Survival Sign-in System," stockpiles supplies for an entire city in an infinite spatial dimension, and uses the "Universal Panel" to recruit a powerful crew. Now, he commands a luxury yacht, traversing the endless ocean and carrying the torch of human civilization.
