An unprecedented change in heaven and earth. It is not a single event, but a combination of multiple disasters. First of all, the spiritual energy recovery on a global scale is out of control, leading to drastic changes in the natural environment, the reappearance of ancient forbidden areas, and cracks in alien spaces. At the same time, a zombie virus originating from the fusion of an unknown alien virus and Earth's biological genes (possibly related to ancient ruins) broke out and spread rapidly. The existence of aura further catalyzed the mutation of the virus, forming sci-fi zombies with both physical threats and supernatural abilities. The catastrophe has been going on for ten years. The original social order has collapsed, and human civilization has retreated into a small-scale gathering with the survivor base as the core.
