Lille had replaced his entire body, using the most advanced neural implants to replace his naturally designed nervous system, and he cut off all the functions he barely used to free up space for his brain to overclock.
For example, his digestive system was completely removed—stomach and intestines replaced by a high-energy drink storage bag that only opened in emergencies. Normally, he relied on the nutrient solution stored in his wheelchair for direct brain nourishment, while the rest of his body parts were powered by electricity or biological energy provided by the wheelchair.
But in reality, as a character who didn't emphasize physical combat, Lille had almost no retained limb motor functions and instead transformed them into precision tool bases directly connected to his brain.
It only needed electricity.
