This novel is based on The Legend of Agim.
After Xiao Guohui awoke from the Shelter Matrix, he lived in the real world's surface for more than thirty years. He was injured during his last expedition to an overseas shelter. After returning to Shelter 77, he prepared to spend his remaining days there with the help of basic medical facilities. By then, the shelter had been deserted, with only Kola, the former leader of the conservative faction and representative of the shelter's human administrators, still at her post. As the bridge between the real world and Agim, Kola, now in her twilight years, spoke with the mostly paralyzed Xiao Guohui about the secret passed down from one generation of administrators to the next. It was connected to the bizarre dreams Xiao Guohui had relived every night on the continent of Agim decades ago...
In addition to his missing limbs, Xiao Guohui's internal organs had suffered irreparable damage. With his life dwindling to its last drop, his only option was to return to the world of Agim, where he could continue his once-absurd legend thanks to the special privileges of a "Prophet" and the difference in the passage of time between the Matrix and the real world.
