Kapitel 334: Negotiations With Zombie!? (3)

" Where are them?!" Zhao Yu seemed to have guessed the origin of these zombies.

"It was used by our people…" Huang Zheng Yi looked embarrassed. He didn't think too much about it at that time.

"We can buy those three genetic elixirs…"

As Zhao Yu remained silent, Huang Zheng Yi continued his explanation, "Our people used the three vials of genetic elixir, and as a result, two of them went mad on the spot, biting others randomly…"

"Those who were bitten by them also turned into madmen, biting everyone in sight…"

"Out of necessity, we could only lock them up…"

"Officer, do you know how to restore their sanity in situations like this?!"

So that was it!

Zhao Yu seemed to understand; the side effect of the genetic elixir wasn't death, but turning them into zombies.
