Over Cloud Gorge Base, the alarm had grown more and more deafening. After a short while, people saw a huge, irregular ring rise around the base. It ascended a hundred meters into the sky before stopping. The buildings on the ground were instantly enveloped by the enormous shadow cast by the ring. As the first ring rose, the second followed suit, rising slowly, and then the third and fourth, up to a total of seven rings, each reaching higher than the last, swiftly taking over half of the airspace above Cloud Gorge Base. It appeared almost like a miracle, with countless turbines spewing blue flames beneath each ring.
The survivors who had just arrived at Cloud Gorge Base did not know what those were and looked on with confusion. In contrast, the long-term residents had understood upon seeing the massive rings ascend that an onslaught of a two million-strong zombie horde was an exceedingly grave matter.
