While thinking about the purpose of this level-six powerful being, Lin Qiao continued approaching the two vehicles. She didn't get too close, but stopped about ten meters away to quietly observe the area surrounding the vehicles.
Through observation, she discovered that the surrounding zombies had been following the human scents emitting from the vehicles and slowly gathering toward this area.
Lin Qiao sniffed at the air and found that the human scent in this area wasn't really strong, but was actually quite faint, as a large part of it had probably been blocked by the vehicles.
The zombies nearby were able to sense the human scents from the vehicles, but the ones who were further away couldn't sense it at all. Therefore, all the surrounding zombies had wandered to this area by chance before detecting the scents of human beings and coming at the two vehicles. However, the shooters in the vehicles would blow their heads up before they could approach.
