Ian used his sword to pry open the chest of the mutant, and discovered that the parasite was not 'entwined' around the spine but that it was actually a part of the spinal cord—the parasite enveloped the mutant's spine like a neural structure, causing the brown-red worm body to spread throughout the mutant's entire body, wrapping around the stomach and extending into the intestines, taking over the digestive system.
At its tip was the mutant's original brain.
—This parasitic worm had completely replaced the mutant's neural structure and had taken full control of the body!
The original mutant was left with just a carcass, its spinal cord and all neural systems had been consumed and replaced by the parasite!
Narrowing his eyes, Ian's mouth curved into an arc of interest as he raised his sword to lift the mutant's still relatively intact skull, revealing its inner side full of viscous mucus and the brain cavity with bizarre pustules.
The youth couldn't help but exclaim in amazement.
