A sharp whistle sounded.
The dense swarm of zombies surged from the red mist once more, this time in numbers greater than ever before, crashing into the outer wall with a direct sound.
Su Changxing maintained his steady frequency of arrow shots, suppressing the zombies' progress in climbing upward, and not a single zombie managed to climb up the outer wall within his line of sight.
So far, nearly a hundred zombies have died under his arrows.
A scream rang out.
Shen Jinxuan's eyes trembled as she shouted to Su Changxing, "Zombies have already broken through up here."
Su Changxing kept his shooting frequency up, saying in a calm voice, "No problem, check the situation by the door and guard it."
Seeing Su Changxing's composed demeanor, Shen Jinxuan felt reassured and stood by the door, looking into the corridor where no zombies had yet charged down, seemingly already dealt with.
