Outsiders watched the spectacle; insiders saw the craft.
The core criterion for judging whether the Healing and Regeneration Technique had taken effect was
whether the lead surgeon possessed the ability to stimulate cells at the microscopic level to accelerate their growth, then extract them with precision.
By that standard, even though this was Hyuga Yu's first time performing surgery of this level, Furobuki could already conclude that he had grasped the essentials of the Healing and Regeneration Technique.
The boost the Byakugan provided to Medical Ninjutsu had completely exceeded Furobuki's expectations!
This was hardly surprising.
Before this, Hyuga Yu had already mastered the lower-level ninjutsu of this A-rank Medical Ninjutsu, the Delicate Illness Extraction Technique, to the utmost degree.
He had even used himself as a guinea pig, forcibly opening the Eight Inner Gates by severing and reconstructing the meridians in his brain, deceiving the Caged Bird, and accomplishing the feat of pulling off a substitution under heaven's nose.
Doing this now was merely within Hyuga Yu's expectations.
But the difficulty of the surgery clearly did not lie there.
The difficulty was the same as with the [Byakugan: Wind Release: Chakra Mode] Hyuga Yu wanted to construct—
The patients he had taken over were all "living dead," neither fully alive nor dead. Their lives were already fragile. Even if Hyuga Yu's surgical procedure could ensure that the ultimately fatal lesions would be removed and repaired, the question was
whether the patients could hold on until then. That was the most critical and troublesome issue.
This was also the root cause that had plagued the Medical Team's higher-ups, leaving even a Medical Ninja of Furobuki's caliber unable to save these patients.
In other words, to complete the surgery, save them... restore their consciousness so that, in their final moments, they could
