Diseases and epidemics breed everywhere, demons and ghosts run rampant, the human world is devastated, and all souls struggle to survive.

Thousands of years later, the human race has no access to the mystic, but the disease has been growing and growing outside the Great Wall. It was not until the demonic disease invaded the Great Wall that the human race realized that without the access to the mystic, the disease and epidemic were invincible. But in this era when the human race has no access to the mystical, what should the human race do? . . .
