"Xiao Xie, thank you so much for providing us with such a valuable research material." Dr. Wei smiled and nodded at her, his face full of appreciation.
"It's my duty." Xie Ning's expression was rather detached. She nodded and turned, walking to Gu Chen's side. "Let's go check the east wall. Where do the flocks usually attack?"
Gu Chen gave Dr. Wei a nod of acknowledgment, then took his girlfriend's hand and started walking. "You think there's something strange about those bird flocks too, don't you?"
"I do. It's a bit strange. These flocks of Mutated Birds seem organized. They come to cause trouble every so often, and some can even get past the laser protection shield."
"There must be a Spiritual System Mutated Bird organizing their movements."
"So you're saying these flocks aren't actually coordinating with the zombie tide below, but are acting on their own?"
Xie Ning nodded. Just then, she heard a series of sharp gasps from the edge of the wall.
"Holy crap, what is that?"
