The last boss of the ninja world

An airborne trooper arrived from Konoha's medical team, causing all the members of the medical team to secretly comment.

Since the start of the medical reform, Tsunade has taken over the position of captain of the medical team. She has never accepted an apprentice so far. The paratroopers have followed Tsunade as an intern since they arrived. Their background and identity will inevitably arouse suspicion.

Fortunately, Tsunade's prestige was strong enough that Tsunade had no objection, and the members of the medical team did not dare to openly discuss it.

Tanino Musashi, who is unaware of his colleagues' thoughts, has been in trouble recently.

Tsunade is gentle and generous towards her friends, but she is very strict towards her followers and apprentices.

Starting on the second day of the report, Tsunade gave Musashi an order to master the changes in the nature of Yang chakra within three months.

[Yin] attribute chakra is the aggregate of energy.

Ninjutsu related to the change of [Yin] attribute properties include [Shadow Imitation Technique], [Shin-Chan no Jutsu], part of [Illusion Technique], part of [Sealing Technique], etc., which are ninjutsu that directly use powerful energy to act on the human body.

The [Yang] attribute chakra is the aggregate of physical abilities.

Ninjutsu related to the change of [Yang] attribute properties include [Doubling Jutsu], some [Medical Ninjutsu], etc., which are ninjutsu that directly act on one's own body or the body of others.

Tsunade's order is to master the changes in [Yang] attribute properties, rather than simply mastering [Medical Ninjutsu].

To master a certain ninjutsu, Musashi only needs to remember the order of the seals and practice persistently. No matter how talented he is, he will one day be able to use the ninjutsu proficiently.

But mastering certain property changes requires understanding.

For example, Uzumaki Naruto mastered the changes in the nature of [Wind Release] after a long period of understanding, such as leaf training, waterfall diversion training, etc.

Having a certain attribute in the body is not the same as mastering the changes in the properties of that attribute. The former is a ninjutsu that can release the attribute, while the latter is a ninjutsu that can use the changes in the properties to develop new ninjutsu.

"so hard……"

In the research room, Musashi scratched his scalp and rubbed it.

To master the changes in nature, no matter how good the teacher is, even if you tell the answer directly, you still need to understand it yourself.

Kakashi had demonstrated the change in nature of Naruto's wind attribute countless times, but Naruto couldn't understand the key.

"It would be great if I could also have multiple clones..."

After countless failures, Musashi simply began to lose his temper, lying on the chair dejectedly and worried.

Shadow Clone Musashi Kai, but unfortunately Musashi could only create one shadow clone, and he exhausted himself every time and still couldn't get the point.

"If you want to give up, I can approve your application to leave the team now!"

Seeing Musashi lying down lazily, Tsunade leaned behind Musashi with a straight face and shouted sternly.

There was no trace of the gentleness he had before, which made Musashi hate and fear him, but he didn't dare to refute, so he had to hold his head and cheer up again.

"Sister, I won't give up!"

Musashi assured him firmly.

"Yang attribute is the power of the physical body. If you can't find the direction, you can try to make a small opening in your arm, and then feel the energy lost by your body."

When Tsunade saw that Musashi had regained his energy, she was harsh again and again. In fact, she suspected that Musashi wanted to take this opportunity to deliberately establish friendship with her. He came to the medical team to gain gold, rather than sincerely wanting to learn medical ninjutsu.

Tsunade was very confused when she received the news that Musashi was going to report to the medical team.

Nowadays, the rumors are becoming more and more like the same thing. Even the Hokage opened a back door for Musashi and wanted to bring them together.

Tsunade refused in her heart, but when she thought that Kato Dan's soul lived in Musashi's body, Tsunade could not refuse Sarutobi Hiruzen's kindness.

Relatives are leaving one after another. Although the medical team is busy with work, by staying in the medical team, Musashi does not need to perform dangerous missions. Even if there is another war, the medical ninja will be protected and stay at the rear.

She really didn't want to lose again.

"Thank you sister!"

Musashi understood that Tsunade was imparting her experience to him, and he was overjoyed and bowed deeply to Tsunade to thank him.

He really wanted to become stronger, and he also really wanted to learn medical ninjutsu. Although he did have a slight attraction for Tsunade, most of the time, Musashi's attitude towards Tsunade was that he regarded Tsunade as a sister with whom he had a close relationship. That’s all.

Well, that's all, Musashi added internally.

Tsunade left with satisfaction, leaving Musashi alone in the laboratory.

"Try to open a wound on your arm and feel the loss of physical energy..."

Muttering, Musashi overcame his fear and used a scalpel to cut a one centimeter long wound on his left arm.

Before Tsunade reminded him of such self-mutilation, Musashi would never have thought of such a way.

Blood slowly overflowed from the wound.

Musashi closed his eyes and used chakra to look inside his body.

"Perceive with your heart, not with chakra."

Tsunade returned to the laboratory again. There was nothing wrong with taking a detour, but she couldn't bear the thought of Musashi being like herself and leaving herself scarred.

"Don't use chakra to sense?"

Musashi was a little confused, but still believed Tsunade's advice.

Giving up looking inside with naked eyes and chakra, Musashi let go of his mind.

It felt like there was an ant or a mosquito on my arm, and I felt slight pain from time to time.

After a long time,

There was a pool of bright red blood on the table, and the wound was about to heal itself. Musashi suddenly opened his eyes.

There was great joy on his face, and he picked up the scalpel again without hesitation and made a deeper wound next to the previous wound.

He didn't understand the reason, but chakra was decreasing with the loss of blood.

Even though I didn't see any loss of chakra when I looked inside, the total amount of chakra in my body has decreased. This is contrary to common sense. The chakra must have flowed out through the wound.

The chakra flowing out is the energy of the physical body!

"leukocyte?"

In the world of Naruto, the physical fitness of human beings is much stronger than that of people on Blue Star. Even without any treatment, Musashi's wound healing speed is hundreds of times faster than that on Blue Star.

The main cause of wound healing on Blue Star is white blood cells.

"I understand!"

Musashi was overjoyed and felt the process of blood gradually coagulating.

The essence of [Medical Ninjutsu] is to speed up the patient's self-healing speed!

Both Tsunade and the First Hokage have extremely strong self-healing abilities, which are special abilities brought by [Yang] attribute chakra.

In a daze, Musashi sensed the existence of that magical energy. He couldn't tell what it was, but it did exist.

Everyone has [yin] and [yang] attributes in their body, which is how Kishimoto describes it in the Book of Ninja.

Sensing the existence of the Yang attribute, Musashi began to try to turn the chakra in his body into that magical energy.

One minute, two minutes, three minutes...

Half an hour later, a dark green chakra light suddenly appeared on Musashi's wrist.

[Medical Ninjutsu] Most of them are Unseal Ninjutsu, and Seal Ninjutsu generally have specific therapeutic effects. Only ninjas who are proficient in the changes in Yang attributes can be called medical ninjas in the true sense.

The dark green chakra light group is the [Yang] attribute chakra group!

A dark green light group appeared, and the healing of the wounds began to accelerate at a speed visible to the naked eye. After a while, the two wounds disappeared without a trace.

"This is the change of the [Yang] attribute. I finally learned the change of the [Yang] attribute!"
