With the roaring of the excavator, the sand was shoveled onto the truck.
Such a commotion, yet no other zombies appeared, which puzzled Li Yu.
Seeing Bai Jie still investigating, Li Yu turned his gaze away from the river and approached them, asking, "How is it? Any findings?"
"It must be influenced by the water quality. The mercury and lead content in this water is more than ten times that of normal water. Perhaps the zombie was affected by the water," Bai Jie said, lifting her head.
Upon hearing this, Li Yu thought for a moment and asked He Chao who was nearby, "Are there any chemical plants around here?"
He Chao thought for a bit and replied, "I remember, upstream, there's a chemical plant. I recall that before the apocalypse, it made the news because local residents collectively opposed its construction, but somehow, it still got built."
Li Yu frowned; his intuition told him that the change in the zombie was definitely related to the chemical plant upstream.
