章 170: Chapter 169 It's not okay now

It was much smoother than during the day, although the change of routes played a role, when Gao Yuan penetrated much deeper than he had in daylight, he still didn't encounter a large scale pursuit by zombies.

Zombies had begun to appear in larger numbers on the road ahead, scattered around with about a dozen or so, but one must not underestimate these dozen zombies – if detected and chased by them, a large swarm of zombies could quickly be drawn in.

Gao Yuan had always suspected that zombies had a unique way of notifying their own kind of prey's presence; at first, he thought it might be ultrasound, but scientists at the base had experimented and found no evidence that zombies could emit ultrasonic or infrasonic waves.

Should he just run straight past? Even if discovered by zombies, they wouldn't be able to catch up with him, but doing so would seem to have the same effect as during the daytime.
