Sea Level Rises 70 Meters, I Strike Gold

When catastrophic heatwaves melt the Antarctic ice caps and flood the world under 70 meters of ocean, civilization crumbles—but one man thrives.

In this flooded apocalypse where survival is luxury, he doesn't just survive—he becomes the king of a new world order.
