September.
The temperature dropped to zero degrees.
The acid rain continued to fall.
But now it began to mix with tiny hailstones.
In less than twenty days, the temperature plummeted from over seventy degrees above zero to zero.
Almost three to four degrees a day.
The sky remained murky grey, one couldn't see their own hands when they stretched them out.
The ongoing acid rain made the human living environment even worse.
And the zombies were the last straw that broke the backs of many Survivors.
At the Big Camphor Tree Base.
The ever-increasing zombies did not diminish but continued to grow in numbers.
In theory, they were continuously using the Mobile Switch Blade and even employed the Crossbow to snipe zombies on the walls, but their numbers didn't decrease.
Fortunately, the continuous darkness and the Zombie Tide meant the bodies of the zombies under the walls were devoured by other zombies, preventing a pile-up of corpses.
