Once the core was finished, it was time to implant it inside his skull.
Li Chen was already thoroughly practiced in opening skulls and confident he could complete the operation flawlessly, so he pressed on without pause.
First, he sat at the table and, with a click, removed his own head from the Keen Warrior body, setting it steadily on the tabletop.
Then he released his Divine Sense, controlling the Keen Warrior body with his mind as he concentrated Magic Power along the blade and began the operation.
As Li Chen worked his art, Gang Edge gathered over the steel blade, making it incomparably sharp. The moment it touched the bone, it easily melted through it.
Li Chen kept his Divine Sense locked tightly on his own head. Following his established plan with utmost care, he started at the lambdoid suture and removed most of the back of his occipital bone.
Then Li Chen applied the blade to the occipital bone, deftly hollowing out its center and discarding that portion of bone.
After that, he connected threads to the Auxiliary Brain with the Silk-Threading Art and slowly pressed it into the opening.
This specially made core had a plate-like shape fitted to the contours of his skull and slotted neatly into place. Its rear casing perfectly replaced the discarded bone, providing stronger protection, while the actual working components lay flat against the occipital bone, minimizing the possibility of pressure on his brain.
Once this was done, Li Chen fitted the piece of occipital bone back into place, bonded it with refined gold, and fused the seams he had opened shut again.
This "welding" process took up more than eighty percent of the entire operation. After all, fitting the core was only a simple modification; the reinforcement he performed along the
