Blue Star Quarantine Province

On New Year's Eve, a meteor shower streaked across the sky. Xu Yan, like everyone else, thought that was the most beautiful blessing for the New Year. A year later, a strange disease spread. The symptoms of infected people are strange and changeable, from arthritis to anthrax, the symptoms of all known diseases switch repeatedly in the patients. Three years later, the vaccine became available. The vaccinated are called "new humans" and their physiques are strengthened and their aging is slowed down. The one thousandth person who cannot be vaccinated is called "old humanity". Xu Yan is one thousandth of that. He was driven into a quarantine area and imprisoned within high walls. Here, he saw the real desperate situation - not the virus, but what was left of humanity after being abandoned by the times. He tried to re-establish order among the ruins, trying to gain a semblance of dignity for the people within the walls. But inside and outside the high walls, there are undercurrents surging. The promise of the alliance, the truth about the vaccine, the deepening rift between the new humanity and the old humanity—— Xu Yan gradually discovered that everything he believed might not be true. And who was this high wall built for?
