The first shot cracked through the air before Li's command finished echoing.
Chen Minghao fired from the left window, his rifle bucking against his shoulder as the round punched through the lead zombie's skull.
The impact was clean—entry wound centered, head snapping back from the force—but, unlike before, the body didn't drop right away. It staggered forward two more steps, its momentum carrying it closer to the gate before its legs finally gave out and it collapsed onto the pavement.
Commander Li registered the delay without comment, his own rifle already tracking the next target in line.
The second zombie took a headshot from Liu Zhenyu's position, the bullet tearing through bone and brain matter, but it continued its advance for another three steps before falling. The pattern repeated across the defensive line as more rifles opened fire in controlled sequence.
The sound of gunfire built into a steady rhythm rather than chaotic noise.
