The evil Senju Clan!
Damn Senju Tobirama!
Inside an office at Konoha Hospital, Uchiha Dan gnashed his teeth and cursed inwardly.
Whenever he thought of his current predicament, Uchiha Dan's hatred for Senju Tobirama was simply uncontrollable.
He wished he could dig up Senju Tobirama's grave, exhume his corpse, and grind his bones to dust.
Seven years ago, he died in a car accident and, in a daze, transmigrated to the Ninja World, merging with the soul and memories of a 10-year-old boy from the Uchiha Clan, becoming Uchiha Dan.
On the same day, a relieved Uchiha Dan happily walked through the streets of Konoha and saw Senju Tobirama for the first time.
The moment he saw Senju Tobirama, a notification sound suddenly rang in Uchiha Dan's mind.
"Ding, the system has been activated! Host has gained all of Senju Tobirama's talents (upgradable)!"
The sudden notification startled Uchiha Dan, followed by a surge of ecstasy.
But when Uchiha Dan, unable to suppress his joy, looked up, he met Senju Tobirama's wary and scrutinising gaze directly.
The latter's cold, monster-like eyes made Uchiha Dan feel as if he had instantly fallen into an ice cellar.
Why the hell are you looking at me like that?
You're not going to kill me, are you?
Just because I looked at you an extra time in the crowd?
Is there no reason anymore?
Fortunately, Senju Tobirama was in a hurry to go to Cloud Ninja Village for peace talks with the Second Raikage at that time.
So he only warned Uchiha Dan with a cold glance before quickly leaving Konoha, surrounded by his disciples and guards.
Seeing Senju Tobirama leave, Uchiha Dan breathed a huge sigh of relief.
He probably knew why Senju Tobirama's gaze towards him was off.
Senju Tobirama was already wary of the Uchiha Clan.
Uchiha Dan's sudden frenzy earlier made Senju Tobirama feel a strong sense of familiarity; it was the kind of look he himself would have when conducting research.
In Senju Tobirama's eyes, this kind of look was a super dangerous signal.
This child must not be allowed to live!
Senju Tobirama was a ruthless character and would not show mercy just because Uchiha Dan was only 10 years old.
So Uchiha Dan shouted in his heart at Senju Tobirama: "Yashiyare! (Go to hell!)"
He knew that this time, Senju Tobirama would be severely wounded by the surprise attack of Kin-Gin brothers, who instigated a rebellion, during his alliance negotiations in Cloud Ninja Village.
Finally, to protect his disciples, he would draw away the enemies and fall directly.
Thinking of this, Uchiha Dan's mood improved considerably.
You dared to glare at me; those who glare at me die!
Sure enough, not long after, news of Senju Tobirama's death spread throughout Konoha.
The entire Konoha was enveloped in an atmosphere of sadness, but it made Uchiha Dan breathe a huge sigh of relief.
Just when he thought he could rest easy, the tragic days still arrived.
Because Uchiha Dan discovered that as soon as Hiruzen Sarutobi, who had just succeeded as Hokage, returned to Konoha, he was immediately put under surveillance.
Not only was he monitored, but he was also inexplicably expelled from the Ninja Academy, losing the opportunity to become a Genin upon graduation.
Furthermore, he was ordered that from now on, Uchiha Dan could not undertake any form of training, nor could he learn any Ninjutsu; he could only live under surveillance as an ordinary person.
Are they afraid I'll become strong, and also afraid I'll run away?
So they want to completely cripple me?
It wasn't easy to transmigrate to the Ninja World; who wouldn't hope to gain powerful strength, with Tsunade on the left and Mei Terumi on the right?
But he died before he could even start.
Just because Senju Tobirama looked at him once in the crowd, his whole life was ruined.
The most tragic transmigrator, well deserved.
Even more, Uchiha Kagami, an elder of the Uchiha Clan, for the first time became uncharacteristically forceful and, because Uchiha Dan had violated clan rules, stubbornly expelled him from the Uchiha Clan.
For a long time afterwards, whenever Uchiha Dan made even a slight movement, a squad of ANBU Ninja would take turns monitoring him, an astonishing display.
He didn't even need to think; he knew for sure that Senju Tobirama must have given some instructions to his disciples before he died.
So, Senju Tobirama, what grudge do I have with you?
Why won't you let me go even after you're dead?
It was just a glance, do you really have to be like this?
While hating Senju Tobirama to the core, Uchiha Dan felt a strong sense of powerlessness rise within him.
His adoptive parents had died in the prolonged First Shinobi World War when he was very young.
Therefore, Uchiha Dan had not received the traditional education of the Uchiha Clan; all the knowledge he learned was from the Ninja Academy.
He hadn't shown much talent, and at 10 years old, his strength was only slightly better than a rookie Genin.
In this situation, Uchiha Dan had no one to turn to.
Even if he had all of Senju Tobirama's upgradable talents, what good was it?
Did he dare to research? Did he dare to train?
With so many eyes on him, if he showed even a slight abnormality, it was easy to imagine what would await him.
In the years since becoming Hokage, Hiruzen Sarutobi had been very decisive in his actions.
So for these seven years, Uchiha Dan could only engage in theoretical thinking and research day and night in his mind.
He pondered the principles of various Ninjutsu, the feasibility of improving various Ninjutsu, and the feasibility of creating Ninjutsu for specific purposes.
However, none of these had yet been put into practice.
Fortunately, the family that adopted Uchiha Dan was very kind and took good care of him; after seven years of living together, they almost treated him as their own son.
Especially after a reluctant Uchiha Dan displayed astonishing medical talent, his unsuspecting adoptive father, Wave Wind She Ren, took it upon himself to use his connections to send him to Konoha Hospital as an apprentice.
Perhaps thinking that a doctor, even a Medical Ninja, posed no threat, Hiruzen Sarutobi didn't interfere, effectively giving his tacit approval.
This allowed Uchiha Dan to become a Medical… no.
Just a doctor, because he had no Ninja title and could not become a Medical Ninja, even though he had already mastered quite a few Medical Ninjutsu.
"Dr. Dan, there's an injured person who needs surgery!"
Just as Uchiha Dan was continuously cursing Senju Tobirama in his mind, a nurse ran into his office, speaking urgently.
"Is it a Ninja or an ordinary person?" Dan asked as a matter of routine.
Everyone in the Hospital knew that Uchiha Dan would use different treatment methods when treating Ninja and ordinary people, so this question didn't seem abrupt.
"It's a Ninja!" The nurse answered quickly, without suspicion.
"I'll be right there; prepare the operating room!" Dan said, while tidying his specialised medical kit.
Inside the operating room.
Uchiha Dan quickly stitched and bandaged the gruesome wound on the injured person's hand.
"How do you feel?" Uchiha Dan asked the injured person with concern.
"Dr. Dan, I feel much better," the Ninja, relieved to have saved his arm, replied.
"Next, I'm going to perform some treatments to help with your recovery."
Uchiha Dan nodded, taking out silver needles from his medical kit and saying seriously.
"Try to perform the Ninjutsu you're most skilled at. You don't need to actually use it; just simulate the Chakra's flow path within your body during the jutsu. Remember, the slower, the better."
"Um... Doctor, why is that?" The injured Ninja asked, somewhat confused.
"You don't want to recover faster?" Dan feigned displeasure, frowning as he asked.
"I understand!" The Ninja no longer hesitated. "I'll do it right away!"
After saying that, the injured Ninja raised his severely injured arm and, along with his other uninjured hand, began to slowly form hand signs.
Uchiha Dan placed his hand on the injured Ninja's abdomen, carefully sensing.
