"What do you mean by that?" Kate curiously asked.
"Let me ask you something... If someone is really directing them from behind, why are they leaving the city?"
The question caught Kate a little off guard, as she couldn't really think of an answer.
"Is it because they are scared of something?" Kate threw her random guesses.
"Maybe. But it's probably because they want human flesh... Remember what we saw when we encountered that zombie family?"
As Kate thought back to that exact moment, she suddenly realized what Xiaoyun was talking about.
"Human flesh?"
"Exactly. Whoever is leading this zombie horde has run out of human flesh to eat in Shenzhen."
"Wait, that means the entire city is..."
The two fell into silence as the idea of not having a single human alive sounded crazy for a city as big as Shenzhen.
