This was exactly what Sparrow had feared. He quickly pulled back, trying to find another route, but no matter which direction he took, obstacles blocked their way.
The city was unreachable. Worse, as they flew over the forests, small villages, and towns, they noticed unusual restlessness—something was stirring below, making the land just as dangerous as the sky.
With no other choice, Sparrow retreated and set course for City A's hidden base. There, he could use the satellite phone to contact his master and young madam, informing them of the troubling signs they had witnessed. The zombies were migrating toward City B, and the mutated animals were becoming increasingly aggressive. At this rate, returning by either air or land was impossible for him and the others.
