Hyuga Ningyuan naturally started with herbal medicine.
He had an entire Barefoot Doctor's Manual stored in his mind—the only problem was that modern herbs didn't match up with those of the ninja world.
Once he memorized both herbal texts, he could naturally identify the plants common to both worlds.
After that, he could directly use them to treat illnesses!
Don't underestimate the Barefoot Doctor's Manual just because it was meant for barefoot doctors—that's not the case at all.
This book certainly couldn't be called the pinnacle of modern medicine, but it was at least a comprehensive medical compendium from the 1960s, covering traditional Chinese diagnostics like observation, auscultation, inquiry, and pulse-taking, acupuncture and massage, common herbs, battlefield first aid and treatment, various acute conditions, infectious diseases, internal and surgical medicine, pediatric and gynecological common ailments, trauma, and even ENT and ophthalmology.
Mastering this single book would make one a divine physician in ancient times, and the same applied to the ninja world, because medical standards there, excluding chakra, weren't particularly high either.
If supplemented with chakra techniques, while it might not cure every disease, treating 99% of them should be no problem.
The remaining 1% would be viral infections like smallpox, rabies, Ebola, and AIDS—but then there was the Delicate Illness Extraction Technique in medical ninjutsu.
This technique could only extract diseases caused by microorganisms, but if the user's spirit continued to evolve and the technique upgraded to the viral level, even those terminal illnesses could be treated.
At that point, it would truly be a cure for everything!
With the Arcane Brush Palace at Level 5, Hyuga Ningyuan had a photographic memory.
He first memorized the Barefoot Doctor's Manual, then the Ninja World Herbal Compendium, followed by Human Anatomy, Human Skeleton, Understanding of the Five Viscera, Chakra Meridians, and Poison Identification and Antidotes.
After memorizing everything, he began searching the [Arcane Brush Palace] for all the biology, medicine, and pharmacology knowledge, secret formulas, prescriptions, and videos he'd seen in the modern world, integrating them into his own knowledge system.
He also activated his Byakugan, scanning his body inch by inch, cross-referencing everything with the books' knowledge.

"Reading books actually gives experience?" Hyuga Ningyuan was startled, then figured it made sense.
After all, reading was the proper way to learn—scientists who built rockets, nuclear bombs, and fighter jets created everything from scratch, and they didn't level up by building rockets either.
Alternatively, skills could be divided into theoretical skills and experiential skills.
Theoretical skills, like mathematics and physics, could be leveled up purely through study and paper-based deduction.
Skills like painting and calligraphy—no matter how many books you read, you had to practice to improve.
Those were called experiential skills.
Medical Skill should be a combination of theory and practice, but the normal learning process was theory first, then practice—so no problem.
As he frantically memorized and studied, his Medical Skill level grew rapidly.
[Ding, your Medical Skill level has increased to Level 2]
Equivalent to a medical undergraduate graduate.
[Ding, your Medical Skill level has increased to Level 3]
Doctorate achieved.
[Ding, your Medical Skill level has increased to Level 4]
Residency training—wait, Medical Skill didn't have branches, did it?
Apparently, there were quite a few branches: pediatrics, gynecology, internal medicine, surgery, orthopedics, and even proctology, the specialty of transmigrator big shots.
But the system remained silent, clearly believing that with Hyuga Ningyuan's learning ability and operational skill, there was no need to specialize.
He should become a generalist big shot!
[Ding! Your Medical Skill level has increased to Level 5]
[You have obtained the trait: Benevolent Medical Practice]
[Benevolent Medical Practice: Your medical ninjutsu effectiveness +30%, the effectiveness of any medicine, prescription, or talisman water you create +30%, side effects -30%. You gain a healer's aura, patient and family trust +30%]
A massive chunk of comprehensive medical knowledge and treatment experience was suddenly crammed into his mind. Hyuga Ningyuan felt a momentary dizziness, but under the effect of [Mirror Water], he endured it without injury.
Then he saw that the Medical Skill subject had also unlocked a trait.
Medical ninjutsu effectiveness +30%, combined with White Swan's healing effect +40%, meant his medical ninjutsu was 170% as effective as others'!
And that didn't even factor in the Hyuga clan's innate chakra intensity.
The effectiveness of any medicine he created was boosted by 30%, with side effects reduced by 30%—this allowed Hyuga Ningyuan to prescribe freely.
Every medicine had its toxicity, but under this trait, the toxicity was greatly weakened while the effects were greatly enhanced.
The healer's aura increased patient and family trust by 30%, greatly reducing the risk of medical disputes.
Not that he was afraid of them anyway.
"Right now, my medical level is about that of a full-department chief physician," Hyuga Ningyuan silently savored the experiential memories in his mind. Powerful, but still within the bounds of scientific understanding.
If supplemented by the trait's effects, it could reach the level of a top-tier hospital director. Combined with medical ninjutsu, even academicians in medicine would fall short.
Oh, I don't actually know any medical ninjutsu yet—never mind, then.
But even without medical ninjutsu, his skill was enough to treat 95% of the diseases at Konoha Hospital.
The 5% that can't be cured—that's just a lack of the right tools, or diseases that require Medical Ninjutsu to treat, like the bridge in a heart bypass, the guidewire in an interventional surgery, or the laser in laser surgery.
From a medical novice to a Medical Dao Grandmaster, total time taken...
He glanced at the system time—roughly three hours.
It wasn't even mealtime yet. Too absurd!
"Arcane Brush Palace!" Hyuga Ningyuan finally realized his core skill was the Phoenix Genealogy Chart, but the Arcane Brush Palace was no less important!
This thing massively boosted his wisdom, mental strength, and learning ability, letting him remember everything at a glance and draw inferences from one instance.
Plus, the [Mirror Water] effect—Heart Like a Mirror, Perceive All Things—made it feel like he had a permanent low-tier Brain Overclocking.
How terrifying was Brain Overclocking?
Eddie could instantly conceive a book bursting with inspiration and excellent prose, learn piano in a flash, or pick up a foreign language in moments.
Lucy relied on this to ascend to godhood, and big shot Chen Ang used it to show off across myriad worlds.
If not for the [Mirror Water] effect keeping his heart calm as still water, Hyuga Ningyuan felt he'd already be floating on air.
"Looks like there's nothing left to learn. What now?" Hyuga Ningyuan flipped through the book in his hands—he'd just skimmed it all in one go. Sarutobi Biwako thought he was just getting a general overview, but she had no idea he'd already mastered medical skills and become a Medical Dao Grandmaster.
Now he'd memorized all the books, his medical skill level was maxed out, and there was no need to read anymore. Yet he had nothing else to do.
Tell Sarutobi Biwako he was done learning?
No way. Half a step ahead is a genius; a full step ahead is a freak. He didn't want to steal the spotlight.
"Since I've got nothing better to do, I'll fuse some skills."
Hyuga Ningyuan turned his attention to the four skills: Blade Art, Spear Art, Staff Art, and Sword Art.
