From the video, many people could see that there were soldiers clad in exoskeleton armor suits. After some investigation, it turned out these soldiers all belonged to the Peace Party's armed forces.
Seeing the Level 7 zombie wreaking havoc on buildings, killing anyone it encountered, bodies rising again to mutate into miniature, low-tier versions of the silver lava giants, then to the distant Jiuge residents who lifted up drowning Peace Party soldiers to offer as sacrifices, all to exchange for their own safety, and finally, to the Level 7 zombie brazenly bypassing the Peace Party soldiers to directly target the residents of Jiuge behind them.
When the thousands of flame-silver-armored zombies approached the immobile Peace Party soldiers, they actually split into two groups and bypassed them. This scene violently shook the souls of every survivor who watched the video!
