'Damn evil Senju clan!'
'Damn Senju Tobirama!'
Inside an office at Konoha Hospital, Uchiha Raizen clenched his teeth and cursed furiously in his heart.
Every time he thought of his current situation, Raizen couldn't hold back his hatred for Tobirama anymore.
He wished he could dig up Senju Tobirama's grave, unearth his corpse, crush his bones and scatter his ashes.
Seven years ago, he died in a car accident, and muddleheadedly transmigrated into the world of Naruto, merging with the soul and memories of a 10-year-old boy from the Uchiha clan, becoming Uchiha Raizen.
On the same day, having survived the calamity, Raizen cheerfully strolled along the main street of Konoha, and saw Senju Tobirama for the first time.
At the moment he saw Senju Tobirama, a notification sound suddenly rang in Raizen's mind.
[Ding~ System activated. Host has obtained all of Senju Tobirama's talents (Upgradeable)]
The sudden notification sound gave Raizen a huge scare, followed immediately by a wave of joy.
But when Raizen, unable to contain his excitement, raised his head, he met Senju Tobirama's wary and scrutinizing gaze directly.
That cold gaze as if looking at a monster made Raizen feel like he fell into an ice cave.
'Why the hell are you looking at me like that?'
'You're not thinking of killing me, are you?'
'Just because I looked at you again in the crowd?'
'Is there no reasoning left in this world?'
Fortunately, Senju Tobirama was in a hurry to head to the ceasefire negotiations with the Hidden Cloud(Kumo) Village and the Second Raikage.
So he merely gave Raizen a cold warning glance, then quickly left Konoha under the escort of his disciples and guards.
Seeing Tobirama leave, Raizen let out a deep sigh of relief.
He roughly understood why Tobirama's gaze toward him felt wrong.
Senju Tobirama had always been highly wary of the Uchiha clan.
Raizen's sudden burst of madness just now had triggered a strong sense of familiarity in Tobirama's eyes, the kind of look he himself would have during research.
That kind of gaze, in Senju Tobirama's eyes, was an extremely angerous signal.
'This child absolutely must not be left alive!'
Senju Tobirama was a ruthless character, he wouldn't show any mercy just because Raizen was only 10 years old.
So Raizen shouted loudly in his heart toward Senju Tobirama, 'GO TO HELL!'
He knew that during this negotiation trip with Hidden Cloud Village, Senju Tobirama would be ambushed by the rebellious Kinkaku and Ginkaku and suffer serious injuries.
In the end, to protect his disciples and lead the enemies away, he would die.
Thinking of this made Raizen feel much better, 'That's what you get for glaring at me, those who glare at me die!'
———
Sure enough, not long after, news of Senju Tobirama's death spread through Konoha.
The entire village was immersed in a sorrowful atmosphere, while Raizen secretly let out a huge sigh of relief.
Just when he thought he could finally sleep soundly without worry, the miserable days came knocking.
Because Raizen discovered that as soon as Sarutobi Hiruzen, who had just taken over as Hokage, returned to Konoha, he was immediately put under surveillance.
Not only monitored, he was also inexplicably expelled from the Ninja Academy, losing the chance to graduate and become a Genin.
And he was ordered that from now on, he, Raizen, was not allowed to engage in any form of training, could not learn any ninjutsu, and could only live under surveillance as an ordinary man.
'Are they afraid I'll get strong, and also afraid I'll run?'
'So they want to completely cripple me?'
'It was so hard to transmigrate into the Naruto world, who doesn't want to gain powerful strength, with Tsunade on the left and Mei Terumi on the right?'
'But instead, I died before even beginning my journey.'
'Just because I was looked at by Senju Tobirama once in the crowd, my whole life was ruined.'
Truly the most miserable transmigrator deservedly.
What's worse, the Uchiha elder Uchiha Kagami, citing that Raizen had violated clan rules, uncharacteristically became tough and forcibly expelled him from the Uchiha clan.
From then on, for a long time, if Raizen so much as moved his body, an entire squad of ANBU would rotate shifts to monitor him, the setup was shocking.
Needless to think, it was clearly due to instructions Senju Tobirama left for his disciples before dying.
'So, Senju Tobirama, what kind of grudge or hatred do we even have?'
'Why the hell couldn't you let me go even after you died?'
'Just over one look, was it worth it?'
While hating Senju Tobirama to the core, Raizen also felt a strong sense of powerlessness rise in his heart.
His cheap parents had died when he was very young in the long-drawn First Ninja World War.
So Raizen had never received formal education from the Uchiha clan; everything he learned was from the few years in Ninja Academy.
At age 10, with no extraordinary talents shown, his strength was only slightly stronger than a newly promoted Genin rookie.
In this situation, Raizen had nowhere to call for help.
So what if he had all of Senju Tobirama's talents, and they were upgradeable?
Did he dare to research? Dare to train?
With so many eyes watching him, if he showed the slightest abnormality, what would await him was obvious.
In the early years of his Hokage reign, Sarutobi Hiruzen was known for making ruthless decisions.
So for these seven years, Raizen could only spend his days and nights pondering theoretical studies in his mind.
Studying the principles of various jutsu, thinking about possible improvements, considering the creation of certain specialized jutsu for alternative purposes.
But none of it had materialized into anything real yet.
Fortunately, the family that adopted Raizen was extremely kind and took great care of him, treating him almost like their own son over the seven years.
Especially after the unwilling Raizen showed amazing medical talent, his unaware foster father Namikaze Sharito took the liberty of using connections to get him into Konoha Hospital as an apprentice.
Maybe because even a medical ninja posed little threat, Sarutobi Hiruzen didn't interfere with this matter, he tacitly allowed it.
Thus Raizen became a medical… no, just a doctor, because he had no ninja title, and it was impossible for him to become a medical ninja, even though he had already mastered many medical jutsu.
"Doctor Raizen, there's a wounded patient who needs surgery," Just as Raizen was cursing Senju Tobirama internally, a nurse rushed into his office and said anxiously.
"Is it a ninja or a civilian?", Raizen routinely asked.
Everyone in the hospital knew that Raizen used different treatment methods depending on whether the patient was a ninja or a regular person, so the question didn't seem strange.
"It's a ninja!", The nurse quickly replied, without any doubt.
"I'll head over right away. Prepare the operating room," Raizen said as he packed up his special medical kit.

[Inside the Operating Room]
Raizen quickly stitched and bandaged the ferocious wound on the patient's arm.
"How are you feeling?", Raizen asked the injured ninja with concern.
"Doctor Raizen, I feel much better now," The ninja, relieved to have saved his arm, replied.
"Next, I'll conduct some recovery-aiding treatment on you," Raizen nodded as he took out silver needles from his medical kit, speaking seriously.
"Try performing the ninjutsu you are most proficient in. You don't need to actually use it, just simulate the chakra flow path internally during casting. Remember, the slower the better."
"Um… doctor, why is that?", The injured ninja asked with some confusion.
"Don't you want to recover faster?", Raizen feigned displeasure and asked with a frown.
"I understand!", The ninja stopped hesitating, "I'll do it right away."
He then lifted his severely injured arm and, together with his uninjured hand, began forming hand seals slowly.
Raizen placed his hand on the ninja's abdomen, carefully sensing.
