Chapter 45: Zombie Wave (7)
"Sir, the horde appears to be splitting. A large portion has diverted toward NYC," the AI reported.
Zack turned his attention to his satellite feed. Among the swarm, he spotted a peculiar figure—a zombie that looked almost human. Its pale, sunken eyes glimmered with unsettling intelligence. It raised its head and let out a piercing roar, its frequency beyond human hearing.
Within seconds, the horde shifted. Half the zombies veered off, swarming around the construction site and heading straight for NYC. The satellite view showed the split clearly—like a river parting around an obstacle.
"Since when do zombies act tactical?" Zack muttered, narrowing his eyes. "Someone—or something—is giving orders."
"Ego, what do you think?" Zack pressed.
"Just before the horde changed direction, I detected a faint high-frequency sound wave," Ego explained. "It seemed to trigger their behavior."
"A signal?" Zack's mind raced. "Can you trace where it came from?"
"Unfortunately, it was too weak to pinpoint, but it originated about ten kilometers away, near the rear of the horde."
That was the same area where Antonny's team had been bombing earlier. Zack's jaw tightened as a grim realization set in. If there was something commanding the zombies, it had to be dealt with—and fast.
