Seeing the mouse's wounds close at a slow but steady pace, Tsunade saw her disciple in a different light.
While this wasn't a big deal, it should be noted that all the wounds on the mouse's body were closing at the same time.
For a medical ninja, multitasking meant he had a greater chance of saving a seriously injured patient.
A ninja who ends up with most of their body injured after a battle is not someone a novice medical ninja can save. Several medics have to team up to heal the injured ninja's entire body at the same time.
Although her student hadn't yet reached that stage, Tsunade could see that Natsuo had a good chance of matching her Iryojutsu skill. After all, Natsuo was only 7 years old.
"Well done," Tsunade said after Natsuo finished closing the wounds on the mouse's body and she checked that everything was perfect.
"Now, show me your ability to heal muscles and tendons," Tsunade said, wanting to see her disciple's performance.
After all, previously they were only skin wounds and, although numerous, they were very different from healing cut muscles.
With the poor mouse in front of him, Natsuo got to work.
Circulating Yang chakra in the mouse's body, Natsuo saw the mouse's body state on his interface and analyzed his next course of action.
Focusing on the most severe wounds, Natsuo chose one and began to join the severed muscles.
Natsuo's Yang chakra manipulated the severed muscles and stretched them before reattaching them.
It took Natsuo several minutes to heal the most serious damage before he could heal the minor wounds.
And with a little more Yang chakra, the injured muscles slowly healed in 5 minutes.
"Done," Natsuo said as he wiped the sweat from his forehead.
Tsunade picked up the mouse and examined it.
With a smile, Tsuande looked proudly at his disciple.
Although it took Natsuo a while to heal the mouse's muscles, his work was excellent and Tsunade couldn't find any place on the mouse's body where the healing wasn't done well.
"You told me that you haven't been taught how to heal bones yet."
"I will show you how to heal simple bone injuries, and you will practice on your own over the next few days before I assess your progress," Tsunade said, and Natsuo nodded.
Natsuo approached and introduced his Yang chakra into the mouse's body and waited for Tsunade's actions.
Under Natsuo's watchful eye, Tsuande damaged the mouse's bones before slowly beginning to heal them.
Tsunade's chakra didn't fight against Natsuo's chakra and healed the mouse's bones. And Natsuo witnessed this entire process.
"That's all for today"
"You can stay here practicing with the mice in this lab and use it when it's empty."
"Of course, you can also take them if you want to practice in your free time."
"I'll introduce you to everyone at the hospital so you can come and go as you please."
"Starting tomorrow, you have to be here at the hospital and you will follow me while I see various patients."
"You can have your afternoons free," Tsuande said.
Natsuo nodded and they both left the laboratory.
After Tsunade gave him a tour of the hospital, introducing him to everyone, Natsuo returned to the laboratory to 'continue' his practice.
Unbeknownst to Tsunade, Natsuo had drastically reduced his speed.
After practicing every day for the past few years, closing simple wounds was very easy for him.
Regarding healing muscles and tendons?
That was like breathing for Natsuo after practicing so many times during the last year.
Because he wanted to keep a low profile, Natsuo lowered his skill level in front of Tsuande.
While he believed Tsunade wouldn't harm him, Natsuo wasn't as confident about the Third Hokage and Danzo Shimura.
Even though he was now Tsunade's disciple, Natsuo was still an Uchiha.
Alone in the lab, Natsuo practiced all morning before leaving the hospital. Tsunade had told him that she had been very busy the night before, so she would probably be sleeping now.
Before leaving, Natsuo took some mice and knocked them unconscious before placing them in a single cage and taking it with him.
As he left the hospital, Natsuo noticed many doctors and nurses looking at him and smiling.
By increasing his senses, Natsuo was able to tell that his training with Tsunade was already known throughout the hospital at that time.
Natsuo returned the smiles politely and left the hospital in the direction of the orphanage.
And as he walked through the village towards the Uchiha clan compound, Natsuo noticed some people staring at him for more than a couple of seconds.
Natsuo had to accept that gossip travels fast in the village, as his status as Tsunade's disciple was spreading rapidly.
And as expected, Natsuo was greeted with big smiles at the Uchiha clan compound.
From the guards at the gate, everyone he met along the way greeted him.
The adults spoke to him for a few minutes and congratulated him on becoming Tsunade's disciple, while the children looked on with envy.
Natsuo greeted everyone and arrived at the orphanage, where they also kept him busy for a long time before letting him go.
After lunch, Natsuo went to his room and spent the afternoon practicing his chakra control.
In addition to his chakra control decreasing each time his chakra amount increases, Natsuo set out to have absolute control over his chakra in the future.
Out there are not only people stronger than him and with more chakra than him, so great chakra control will be useful to lessen the gap between Natsuo and his opponents.
So, from time to time, Natsuo dedicated a large part of his day to improving his chakra control.
Unfortunately for Natsuo, he couldn't spend the night practicing because Sanjiro came to get him on behalf of the clan leader.
The Uchiha clan was having a meeting at the Naka shrine and the patriarch wanted Natsuo to be present.
Sighing inwardly, Natsuo outwardly smiled at Sanjiro and shortly afterwards left the orphanage after changing his clothes.
.
.
.
As Natsuo expected, the meeting was boring.
If it weren't for the fact that he was able to learn the extent of the Uchiha clan's business dealings, Natsuo would think this meeting was a waste of time.
Upon learning about the clan's business dealings and the money they earned, Natsuo viewed the Uchiha clan in a different light.
In addition to various shops in the cities of the land of fire and farmlands, the Uchiha clan also owned a couple of iron and silver mines.
The money from both mines contributes a large part of the money to the Uchiha clan.
Of course, the Uchiha clan also spent almost everything on maintaining its clan members.
And specifically, to its strongest members.
From what little he could hear, each clan in the village had its own private forces outside of the Hokage's control.
The Hokage could only command these forces in times of war and after having negotiated with the clans.
Of course, although the Hokage had a great deal of power by being in command of the other ninjas in the village, the strongest ninjas in the village were from these clans.
Natsuo saw everyone in the room smile with pride and mentally shook his head because he knew that this situation wouldn't last long.
Unlike clan ninjas, civilian ninjas will be growing rapidly in the coming years, surpassing clan ninjas.
And after the second and third world wars, the Hokage would have the majority of the village's forces in his faction.
From his 3 disciples called the 3 Sannin and Katake Sakumo, there were 4 elite ninjas under the command of the Third Hokage, a force that the other clans did not dare to provoke.
And although the Third Hokage's faction suffered a severe blow after Sakumo's suicide, the three Sannin still existed.
Along with the appearance of Minato Namikaze, the clans found themselves at the bottom of the power scale in the village.
After the second and third world wars, the village clans dwindled without any explanation, and Natsuo could only guess that the elders of these clans died in those wars.
And after suffering so many losses, the clans learned their lesson and kept a low profile.
Natsuo could also tell that these clans harbored resentment towards the Hokage faction because none of them fully supported the Hokage when the village was invaded in the future.
During Orochimaru's invasion during the Chunin Exams and during Pain's attack, controlled by Nagato.
