Chapter 32: Strengthening Serum.

"Ao!"

Xiao Hui howled softly, signaling his cousin to go eat,

then naturally moved to the cave entrance to lie down, taking over the watch duty.

At that moment, Su Lin,

returned to his place and began studying the Strengthening Serum granted by hunting the grizzly bear.

The first combat rating reaching S+ had rewarded him with a vial of Strengthening Serum.

[Strengthening Serum]: Upon consumption, it may fortify random organs and limbs with a 70% success rate; should it fail, the potion disappears.

The introduction to the Strengthening Serum was straightforward and easy to understand.

It's meant to enhance one's organs or limbs,

whereas the Potential Potion developed the potential across various parts of the body.

Then the Strengthening Serum would unlock the genetic shackles of the species, breaking through the limits of potential.

"No wonder it's so rare; just one vial for an S+ combat rating," Su Lin thought to himself.
