"Lingang! Can you hear me?"
Xiaoyun worryingly asked as only gunshots came back from Lingang's transmission.
But after a short moment, Lingang's voice finally came back.
"Yeah, I can hear you. A jockey mutant just jumped over the wall and almost got on top of me."
"Okay. If you need reinforcement, just tell me, and I'll send them over."
Xiaoyun ended the transmission as he shifted his attention back to the battlefield.
The zombies were using the zombies' bodies from the last wave to climb up the wall as the moat and trenches in front of the wall filled up.
With every zombie killed, it created more height for a zombie staircase up the wall.
The firepower from all of the soldiers firing their guns was still able to hold them back.
But as more and more zombie bodies piled up, it finally reached the point where zombies could straight-up run the bodies towards the wall.
