"Changhe Base was initially constructed by the state organization, but after losing contact with the higher-ups, Changhe Base began to build on its own. There were many dangers faced back then, but ultimately the construction was completed successfully. Now, Changhe Base is a massive Survivor Base with walls over a hundred meters high..."
"Whoa, walls over a hundred meters high! Built on flat ground? That's freaking awesome!"
Xiang Bo exclaimed again.
Although the outer walls of Red Maple Base are even higher, reaching thousands of meters, those are not actual walls, but natural mountains.
Even though these mountains are quite steep, this does not mean that zombies cannot climb them, so they still need to send people to stand guard on the mountains round-the-clock to prevent a zombie invasion. Even during the previous ice and snow period, there were teams of people guarding the mountaintop.
