Shinobi World No. 1, Sunagakure, deep within the underground biological research area.
Unlike the usual bustle of research into "Gene Serum" and "Battle Armor," this newly established secret chamber was exceptionally quiet. The air held a mingled scent of disinfectant, nutrient solution, and some exceedingly faint, indescribable energy particles.
Layers upon layers of purification and soundproofing runes covered the walls and floor, ensuring that not the slightest trace of energy or information could escape.

Rather, they were fragments of the purest, most fundamental "chakra affinity guidance units," obtained through his meticulous processing and repeated refinement with Dragon Vein Power, stripping away every possible mental imprint and directional tendency.
They contained no great power themselves and were almost impossible to detect by conventional means.
