Chapter 70 (5k subscription request) The answer is in what Old Du had said!

Not the original zoo?

Sensing Yu Liang's confusion, Tu You explained again, "This isn't the zoo I used to work at. I arrived here after I was 'mutated' into a rabbit."

"I see." Yu Liang nodded, "So the 'animals' here are all staff from Changhong Zoo?"

"Plus a very small number of mutated visitors." Tu You nodded, "Visitors from the same zoo I was from, as well as visitors like you."

"Ah, I understand." Yu Liang now roughly understood the origins of these "NPCs".

"But in the beginning, there weren't any visitors like you in this zoo." Tu You continued, "Back then, although we still had dietary differences, all the staff were united and we lived well together in this zoo."

She looked at Yu Liang, "Until the first group of visitors arrived, until they discovered...human flesh tastes good."

Yu Liang could almost imagine what happened next, but he just quietly listened.
