After the End of the World, the Elite City of Kodian

In 2032, the end is coming. The earth's crust cracked, snow-capped mountains flooded, and the land was submerged and broken into more than a dozen sides. Just half a year later, the human elite renamed the largest continent on the Twelve Sides, and built the Twelve Sides Cloud City above the Twelve Sides. In 2042, 16-year-old Lin Meng got a pass from Kodian City with his outstanding ability. As a "remnant" survivor who did not board the Ark, he was assigned to perform tasks in the parallel digital space on the second day after entering the city.
