"Captain Butler, when do we make our move?" a fully armed combat squad member asked.
Butler took a final puff and threw the cigarette butt at his feet.
They were now on the top of a tall building.
A transport helicopter was parked on the roof.
Butler did not dare to get too close to them, for fear of being discovered.
He wanted to strike when the two sides have sufficiently weakened each other, and then reap the benefits.
Through the telescope, he could see the zombies from the north continuously swarming to the other side, and the corpses had piled up into many hills.
"It's almost time. Gather up and set off!"
Butler walked into the transport helicopter.
In the transport helicopter, more than thirty fully armed combat members were ready to go.
A loud roar was heard as the transport helicopter slowly took off and flew in the direction of the bridge.
Soon, the transport helicopter arrived above the battlefield.
