It's often done during peaceful times.
And the ones who spend a fortune to make such a thing in the mountains are either doomsday enthusiasts or just have too much money, so they can only spend it on this.
At the beginning of the apocalypse, Lin Fan saw a post while surfing the internet.
"Things to Note in the Event of a Zombie Outbreak."
There was a person claiming to be a fanatic of zombies, with immense wealth, who had bought a mountain early on, hollowed it out, and turned it into a secret base.
It seemed a bit similar to the current situation.
I wonder if this base belongs to the guy who boasted online at the start of the apocalypse.
Perhaps it is.
After all, not many people across the country have such idle thoughts.
The gate that should have been tightly closed was torn open violently, creating a huge passage, with some zombie corpses lying at the entrance, and the floor flowing with viscous liquid.
Listen carefully.
You can hear a 'hiss' sound.
