Chapter 165: S-Grade Mutated Mecha Snake

When it was almost noon the next day, Peter found traces of the mutants in a valley. The entire surface of a rock had been burned by the high temperature, leaving traces that looked like charcoal on it.

However, after chasing them all the way here, he didn't discover anything new.

Just as Peter was deciding whether to continue his pursuit, an unusual sound came from the valley. It sounded like a powerful mutant creature.

Rumble!

Rocks began to fall from the valley as a huge snake appeared at the entrance. The moment the snake appeared, a system prompt sounded in Peter's mind.

[S-Grade mutated mecha snake genes detected. Extracting…]

[Extraction failed. Genes cannot be extracted.]

The system prompt surprised Peter as this had never happened before.
