"This is it, Qingshan Camp."
"It's truly magical. Before the apocalypse, we used to come here for training, and there was nothing at all."
Seven well-built, buzz-cut young men stood at the camp's gate, clicking their tongues in wonder.
"This wall looks like it offers no protection, and it's so low, can zombies really not break through?"
One of them said this as he reached out to punch the vine wall, only to see a ring of transparent ripples emanate from around his fist, preventing it from penetrating even an inch.
Another person beside him, seeing this, also stretched out his hand and punched at the air in front of him, and indeed, the same ripples appeared.
"This is a transparent air wall; I wonder how it works," said one of the seven, with glasses, as he ran his hands over the air wall, "Could these vines be fake?"
"Old Four, Old Five, Old Six, stop studying the wall. There's a notice board here."
