During this conversation, you temporarily gained Hiruzen Sarutobi's trust. However, you were well aware that covert observation and probing would still be unavoidable, and it wasn't the time to overturn the table yet.
From that day on, you began to treat patients in the hospital with even greater diligence and effort. On one hand, it was to familiarize yourself with the human meridians and acupoints taught by the Hyuga Clan. On the other hand, it was also to improve Tsunade's favorability, to earn her greater trust, and thereby gain the opportunity to enter Shikkotsu Forest.
As days passed, your Medical Ninjutsu became increasingly refined. Especially in the treatment of bloodline-related fields, you held great authority and were highly trusted by your colleagues in the hospital.
During one medical procedure, you were unexpectedly noticed by Orochimaru, who had come to find Tsunade. He was extremely interested in your unique medical methods and extended a sincere invitation, but you declined, citing your own significant shortcomings.
After some more time, Danzo, known as Konoha's 'Shadow of the Pot', also sought you out. He too was interested in your research in the bloodline field. You knew Danzo's true nature as a treacherous schemer. Your research in this area was purely for Kushina's sake, so you didn't want to get into other troubles, and thus you politely refused him as well.
Of course, during this period, your outdoor activities with Kushina and others never stopped, almost once a week. Through continuous interaction, your bonds with them gradually deepened, and Kushina's attitude towards you underwent a significant change; she would always intentionally or unintentionally start to care about you.
As your interactions became more frequent, your feelings deepened, and your relationship became much closer. Whenever Kushina was unhappy, she would always come to you. Although you initially seemed a bit impatient, your body would honestly accompany her in play.
Gradually, your relationship had developed beyond ordinary friendship, and Kushina had grown accustomed to your company. But you knew that your time was limited and you couldn't always be with her.
So you decided to start training even harder and promised to give her a surprise. Kushina was very happy and expressed her anticipation.
"Are you really sure?"
Upon hearing Takeshi's request, Tsunade looked shocked.
She truly hadn't expected that this child could master Medical Ninjutsu to such a degree in such a short time.
In some areas of research, he even far surpassed her, his teacher.
Initially, she only wanted another money bag; she never really expected this disciple to achieve anything significant in medicine.
After all, he was a Uchiha. Although he could use Mystical Palm Technique, his innate conditions were not as good as others, so Tsunade didn't have high hopes for Takeshi.
But who would have thought that her disciple was so ambitious, forging his own path and becoming self-taught?
He directly transformed into a medical expert in bloodline disease...
"Yes, Teacher, I have made up my mind!"
Through his research on human meridians and special acupoints, Takeshi discovered that when Ninja perform Ninjutsu, they need to circulate Chakra through most meridians and acupoints to succeed.
But in reality, many Ninjutsu do not require Chakra to flow throughout the entire body.
It only needs to be circulated and stimulated in specific meridians and acupoints to be successful.
The method used by those with powerful Bloodline Limits, who forcibly drive and operate techniques with vast Chakra, is incorrect!
This not only causes severe erosion and damage to organs and even cells, but prolonged use will also lead to physical weakness and eventually death.
This discovery was completely an accidental byproduct of his research, and yet it was such a byproduct that inexplicably made Takeshi a medical expert in treating bloodline disease.
Many people came to him because of his reputation, but what Takeshi truly wanted was a method to increase bloodline concentration.
Now his basic theory and practice had been fully exercised; all that remained was the final step of 'flushing the meridians' by entering the Three Great Sage Regions.
"Alright."
Actually, she had long intended to teach Takeshi the Summoning Jutsu.
The reason she hesitated was fear that he would act recklessly and casually attempt Sage Mode.
One must know, this was a technique that even she couldn't master, and the risk of learning it was extremely high; a slight mistake could lead to death.
However, if she gave him a few warnings, perhaps it wouldn't be so serious.
After all, Takeshi was a fairly reliable kid.
Tsunade pulled out the Shikkotsu Forest summoning scroll from her embrace and handed it to Takeshi. Without much hesitation, he decisively signed his name.
Now, all the conditions were finally met.
After successfully contracting with the slug of Shikkotsu Forest, you began the formal experiment of the bloodline purification method. First, you stimulated some special acupoints on your own body to activate bloodline potential, and then you used natural energy to attempt to 'flush the meridians', strengthening the bloodline potential, repeating this continuously.
You attended classes during the day and returned to Shikkotsu Forest at night. When injured, you sought treatment from the slug. Your daily life was extremely regular and incredibly busy.
During this period, Third Hokage Hiruzen Sarutobi came to see you a few times, but each time he tried to indoctrinate you with the Will of Fire. Eventually, you grew tired of it and simply refused to meet him.
Thanks to being both the young clan head of the Uchiha Clan and Tsunade's disciple, Hiruzen Sarutobi didn't say anything to you, but you always felt that his attitude towards you seemed to have changed.
You noticed this, but your mind was entirely focused on increasing bloodline concentration, so you temporarily didn't pay much attention to it.
Just like that, in a blink of an eye, three years passed. Through your unremitting efforts, you finally managed to increase your Indra bloodline concentration.
You could clearly feel your control over Yin Release becoming stronger, your spiritual energy improved, and your ocular Ninjutsu became incredibly powerful. Even in the state of a Three-Tomoe Sharingan, you could activate the Complete Susanoo.
This change made you extremely excited, but you didn't become complacent. Instead, in every subsequent self-experiment, you supplemented and perfected the bloodline purification method until it was completely stable and safe before you began to use it on Kushina.
Mission: Help Kushina avoid a death ending. Mission Progress: 43%
Through three years of effort, Takeshi had increased the mission progress to almost half. And once he increased Kushina's bloodline concentration, it would experience another surge.
"Takeshi!"
At this moment, a girl's call came from the doorway. Kushina's heart leaped with joy. She quickly took off her shoes and walked in.
Her fair, tender feet stepped on the floor. She expertly flopped into the soft sofa nearby, burying her small face and letting out a lazy, sweet voice.
"Takeshi, what surprise are you going to give me?"
"Come over here, and take off your top."
