Naihe Island

It was a world-destroying catastrophe, with meteorites falling from the sky, floods surging into the sky, and then the extremely cold nights and icy clouds covering the sky... After all of this passed, except for the vast ocean of ice, there was only a mere inch of land left in the world and a handful of survivors. But human beings are always tenacious, and they can thrive on even an inch of land. Generation after generation, they have moved rocks into the sea and built tens of thousands of tall buildings from the ground. Towers reaching into the sky reach straight into the sky. On top of the clouds, humankind's new civilization is blooming again. However, after entering the ladder to heaven, who would want to return to that small place again? Above the clouds, you can bathe in the sun and enjoy the breeze, but under the clouds, the sun is not visible and the cold remains. On the "Naihe Island", there are just countless people who have been left behind and want to climb the ladder to heaven.
