Li Ang murmured to himself, "The location where the Spirit Vein has broken is just beneath the skull, in the frontal lobe. The skull and scalp themselves pose an obstacle, so the headdress isn't as effective as I imagined. Perhaps implanting the Fine Gold wire directly beneath the skull could form a circuit—for safety's sake, it would be best to sheathe the Fine Gold wire in an insulating layer. But the problem is... the conditions for a craniotomy just aren't here."
Never mind whether he was the sole neurosurgeon in this world. Even Li Ang himself wouldn't perform a craniotomy on someone else without the means for hemostasis, disinfection, or anesthesia. It was essentially no different from murder.
"And the second method is to find a superconductor with a Spiritual Energy transfer efficiency greater than Fine Gold..." Li Ang mused to himself as he rose from his seat. "If I were given enough time and materials, perhaps there would be hope to find it."
