Chapter 138: Fear of Insufficient Firepower (2nd update, seeking subscriptions)

Outside the shelter.

Seeing the situation was well under control, Shen Congfei had the prepared metal cages ready, trapping all the mutated creatures.

The choice not to kill was, on the one hand, due to the fact that some key ingredients in the antidote needed to be extracted from the mutated creatures.

The antidote injected into the Fanatic Foodie had almost depleted the refined substances stored in the lab.

On the other hand, it was due to the biological enhancement drug.

He vaguely remembered that during the initial test, some components of this drug were also required to be extracted from the mutated creatures.

The remaining ingredients needed to be obtained from the surviving Imperial Five Noble families, from a being known as the Beast Duke.

It was said that only this NPC had such a unique substance.

Shen Congfei didn't know the source of this substance until after the internal test, it seemed like something that only the Beast Duke had, and no one else had it.
