Reborn in Naruto As Madara's Grandson

The torture continues for the next two weeks as I have to memorize a plethora of knowledge.

The herbs and medicines are entirely different from my previous world because of the involvement of Chakra. Though some of their effect are almost the same, but more potent.

For various diseases, there is not much knowledge recorded. Shinobi continues to wage war and during warring periods, hardly anyone lived past Thirty. This reminded me of Itachi's disease.

Kishimoto has a knack for killing overpowered characters in a very unconventional way. Sakumo dies by suicide, Shisui dies by suicide, Itachi dies from an unknown disease. Nagato sacrifices his life, Grandpa Madara is backstabed by Black Zetsu.

Moving on to poisons, similar to medicinal herbs, poisons are also enhanced by Chakra. As for medical Ninjutsu's history, there are lots of incomplete text and record. Only after the formation of Hidden Villages did the shinobis start to compile them.

There is still a lot of knowledge buried within the depths of various clans record which they refuse to pass to others.

I found no records of anything related to 'Sage of Six Paths'. He is considered more of a fable than an actual person. Guess Black Zetsu did a good job of eliminating any trace of him.

'After this boring session of book reading, today we are finally about to start on our first lesson on Medical Ninjutsu, I suppose.'

I had doubts about the authenticity of Tsunade's words when she convinced Shizune and as expected Tsunade appears before us as she speaks,

Tsunade place jars in front of us. The jar has milk and coffee mixed within it.

"To test your Chakra Control, I would like you to separate milk and coffee in different layers. This is a simple test I came up with after pondering for a while. The faster and smoother you can do it, the better your Chakra control is."

She shakes the jars to further mix the milk and coffee.

"Now start! You have half an hour to separate the mixture."

I have good Chakra control. Beside my ninjutsu training, I practiced Chakra Control a lot. The situation turned even worse after the 'Sin Seal'. I have to micro-manage my Chakra consumption in order not to trigger the seal. I infused Chakra more than the necessary amount, the seal would start to suck me dry. So, my Chakra control improved further from this handicap.

I still miss those days when I could spam Jutsus non-stop and dominate anyone with my power. Now, even throwing a Lightning Release Rasengan will trigger the seal and leave me dry. I should pay a visit to Uzumaki Village sometime soon. Anyway, this test will be a breeze for me.

I concentrate Chakra in my hands as I redirect it inside the mixture. I start to fine control my Chakra as it interacted with Coffee and Milk particles. Slowly, step by step, I separate them based on their densities as small layers of milk and coffee form.

Tsunade looks at my mixture and nods.

"You are doing great, Izuna. Looks like your chakra control is quite good. Shizune, milk, and coffee have different compositions. Try to separate them according to that. We can also apply this lesson to extract poison from the body."

I separate milk and coffee in a few more seconds and after a while, Shizune also completes the process.

"Izuna your Chakra Control is up to the standard of a Medical-Nin. As for you, Shizune, you need to train hard in your Chakra control. You can still improve further." Tsunade remarks on our abilities.

"Next step is the 'Healing Technique'. You have to gather chakra in your palms in the shape of an orb and move it over injured areas to accelerate healing. There is also an advanced form of this technique called 'Mystical Palm Technique'. Only a few medical-nin can use this technique."

Tsunade presents a dummy doll to both of us.

"This doll is made up of special materials. Whenever you apply healing jutsu on this doll, the material of the doll starts to expand. There is a small cut on this doll. Your task is to use the 'Healing Technique' to close the split wound. Keep in mind, if you applied too much of the healing Chakra; the doll will inflate and blow from over-expanding due to excessive Chakra."

Both Shizune and I start to use the 'Healing Technique' taught by Tsunade. It is quite easy for me as I copied the entire process with my Sharingan when Tsunade demonstrated the technique. I have also copied the advance version 'Mystic Palm Technique' during the war, but I will improve step by step according to Tsunade's instructions.

In a few minutes, I easily closed the tear and handed the doll to Tsunade. Tsunade checked the doll and nodded,

"You have a good aptitude for Medical Ninjutsu, too bad you are more of a combat-oriented Shinobi. Your fighting skills are more useful than Medical skills."

After Shizune completes the process, Tsunade moves to the next step. She hands over Sakura buds to both of us as he demonstrates the next step,

"During an emergency, you can save a wounded partner or friend, if you can skilfully apply Chakra to their injuries. For this step, you need to bloom this Sakura bud with your Chakra."

'So, I have to provide enough nutrition to the buds to make them bloom. Chakra is versatile as we can use it in several ways.' I ponder over the nature of Chakra energy as I start to apply Chakra over Sakura buds.

After a short while, the Sakura buds bloom with pink flowers as I present them to Tsunade. Tsunade is surprised to see my progress. She praises me,

"Your medical skills are quite good, Izuna-kun. It would be a waste to let them rot in combat. Why don't you become a Combat medic?"

I shook my head and reply to her,

"Tsunade-san! I want to grow strong enough to not even allow my friends and family to get injured. I am learning medical ninjutsu to improve my Chakra control and as a precautionary measure for emergencies."

Tsunade sighs as she looks at Shizune. Shizune is struggling to bloom the bud as her expression is quite strained due to concentration.

Shizune ultimately fails as Sakura buds fail to bloom in the time limit. Tsunade consoles Shizune,

"It's alright. You need a little more practice and you will succeed. After this basic course, the next part will be the handling of Chakra tools. You should be able to infuse healing Chakra in scalpels and other tools while operating on a person.

Healing Techniques can only heal the external wounds, for internal injuries you need to operate on the patient to effectively treat him. We will start on that only after you completely master the basic course and effectively heal people in hospitals.

Izuna, you are ready for treating external injuries of patients. From tomorrow onwards, you can start to practice on patients in infirmary."

"Yes! Tsunade-san."

I spent the next month practicing medical ninjutsu under Tsunade's guidance. Tsunade was surprised to see my proficiency with medical equipment as I handled them like an expert.

After just a week, I even completed a minor surgery which greatly shocked Tsunade.

"Kid! I really hope for you to practice Medical Ninjutsu. You can save countless lives during a battle." Tsunade tries to convince me again.

'If I have enough strength, then there would not be any need for battle. I can suppress my enemies with my strength alone, there will be no injuries or casualties.'

Such thoughts ran through the mind as I once again rejected her idea.

'Maybe I wasn't fated to be a doctor. The day I graduated from my masters and was free to practice; I lost my life on that very day. But still in my days as an intern, I saved plenty of people to earn enough Karma to reincarnate in this world with some cheats. I suppose!'

I even demonstrated the 'Mystic Palm Technique' to Tsunade, much to her surprise. In just two months, I have mastered nearly all the Medical Ninjutsu courtesy of Shadow clones.

I have no interest in Tsunade's 'Creation Rebirth Seal' since I have a healing factor. Her technique is flawed. Creation Technique doesn't repair the old cells instead it hastens the creation of new cells through the 'Cell Division'.

A body's cells can only split and divide only a certain number of times; after it reaches the limit, the body doesn't create new cells anymore. This is the reason why Tsunade's actual appearance was much older than her age. This technique also shortens the lifespan of the user, Tsunade could live so long because of her Uzumaki heritage.

Maybe in the future, I can perfect this technique and help Tsunade preserve her beauty. It is such a waste to let her turn into an old hag.
