"We didn't encounter a single level two or level three zombie." Mo Chenxuan stated, and Qin Wu nodded.
"Don't you think it's strange?" She asked, but Mo Chenxuan shook his head after a moment of thought.
"Not really." He said and began explaining.
"Most zombies evolved after the black rain. It makes sense that the indoor zombies are weaker than the outdoor zombies."
After listening to the explanation, Qin Wu nodded.
Because the apocalypse began at night, there were originally more indoor zombies than outdoor zombies.
However, things changed over time.
After all, many survivors left doors open during their escape, allowing indoor zombies to go outside. As a result, these zombies enjoyed the black rain and consequently evolved.
Unfortunately, the stadium's structure was too complex.
Even if the gates were open, the zombies couldn't go out, and no survivors dared to go in. This caused the stadium zombies to miss the black rain, which slowed their evolution process.
