There Is a Letter Coming from the Cloud

In 2076, the wasteland girl Su Li awakened a "Watcher" Cheng Li who had been sleeping for fifty years in the ruins of the old capital. He lost his memory and only remembered that there was a "key" related to the revival of mankind in his body. In order to find the answer, the two must travel through the 3,000-kilometer death zone to the Wangfeng Post that disappeared on the map. In addition to sandstorms and mutant beasts, they are pursued by various forces: "scavengers" who believe in purificationism, greedy plunderers, and the dark truth about why the world collapsed that is gradually reviving in Cheng Li's mind. This is a journey to find sparks in the graveyard of civilization. While everyone was looking for scraps in the sand, they chose to look up at the long-forgotten starry sky.
