Lier had replaced his entire body. He had swapped out his naturally designed nervous system for the most advanced Neural Implants and cut away every function he barely used, making room for Brain-Computer Overclocking.
For example, his digestive system: he had removed his stomach and intestines entirely, replacing them with a high-energy drink Storage Bag that he opened only in emergencies. The rest of the time, nutrients were delivered straight to his brain from the nutrient solution stored in his wheelchair. As for his other limbs, they likewise relied on the wheelchair for electricity or bioenergy.
But in practice, as someone who didn't focus much on limb-based combat, Lier had kept almost none of his limbs' motor functions. Instead, he had transformed them into precision tool mounts directly linked to his brain.
All they needed was electricity.
His endocrine system was another example. As a modified human with only his brain still original, growth-regulating hormones, hormones related to emotional control, and other regulatory hormones had become far less meaningful. He had kept only the hormones that enhanced his metabolism and brain function, and the glands that secreted them would now be controlled directly by his Neural Implants rather than by instinct.
His Immune System, complex motor system, sensory system, and more could likewise be greatly simplified, freeing up the areas of his brain that supported the body's passive functions entirely. Neural Implants would integrate those areas into Computing Power he could actively allocate, squeezing even more processing capacity out of his brain.
This also concentrated the effects of Lizard Serum and extended the lifespan of Lier's cells overall.
In concrete terms, Lier could use Brain-Computer Overclocking more often, and it was more powerful.
The price was that he had very little of his Native Body left. If another human underwent
