Chapter 113: Another Series of Upgrades! 

While cautiously moving through the Mad Ape Forest, Vincent finally had the time to focus on the system notifications he received.

There was one thing that stuck in his mind.

It was about primal energy. When he assisted in killing Zhang Chen, he received a notification that a few points of his primal energy had recovered.

At the time, he thought it was a one-time event.

But he did not expect that he would also recover primal energy after killing Xu Zheng.

"Is it possible that I can recover primal energy by killing a human?" he thought but quickly dismissed the idea. There was no way he could conduct further research on it.

He might not feel guilt about killing enemies, but he wouldn't harm humans solely for experimentation.

After some time, he finally encountered one of the inhabitants of the Mad Ape Forest.

It was a group of black-furred monkeys.
