By then, Shinra started his hard days, working tirelessly as he learned everything to grow stronger.
Ozu Toshio also gave his everything, training Shinra's muscles to the limit with the power of science and money.
Still, not only did Shinra train hard to improve his physical ability, Shinra also studied the knowledge of high school and anything that interested him, including the armed martial arts.
Whether it was swords, a whip, an axe, a mace, a spear, or even firearms, Shinra easily mastered all of them to near perfection, which stunned everyone silly.
What was this?
Was this Superman?
Shinra's talent was simply so frightening, yet everyone continued to support him since the faster he learned, the more excited Shion became that she didn't waste her time and invested in him to grow even stronger.
Was it tough?
Of course, yet, for Shinra, who was a ninja, and also born from the Uchiha Clan, even if his Chakra was only so-so, it also started to improve after he was taught by Mikoto how to refine his chakra.
Still, even if he had said that his chakra was so-so, it was when he compared it to those famous characters such as Naruto, Sasuke, and many others, but frankly, it was hard for him to gauge how much potential his body had as his knowledge of chakra was limited, but fortunately, Mikoto brought him many records and important books from the Uchiha Clan, so he knew that he had the potential to become a Kage, who was known as the leader in the ninja village.
Still, this didn't surprise him since in the past, after Tsunade, Jiraiya, and Orochimaru left Konoha, the strongest ninja was Uchiha Shishiu, the indecisive fool, who thought all of he did was for the Uchiha Clan, yet the truth, he was being manipulated by Sarutobi and his group before being killed as his eyes were gouged out.
In the world of Naruto, the power of bloodline was everything.
If one wasn't part of the Senju or the Uchiha, then their limit was just that, and it was impossible for them to be beyond that. Some who weren't part of those two clans might be able to become powerful, but their limit was only a Kage level, the leader of the ninja village, and beyond that, it was impossible.
To live peacefully, it was impossible to just rely on the power of Kage, especially when many aliens existed and wanted to devour the planet to become stronger.
In front of those existences, the Kage was just an ant!
Still, even so, his power wasn't bad, especially when Mikoto also taught him about the power of a ninja, from controlling his chakra, refining the basics, and giving him all the ninjutsu he needed.
However, while a Uchiha could learn anything as long as they saw a ninjutsu with their Sharingan, as it had the ability of "Eyes of Insight," making them able to learn anything in near-perfection almost instantly, there was still a limit since everyone had something known as an affinity.
What is affinity?
It means whether a ninja can learn a ninjutsu of a certain element or not.
There are many elements, but the basics are fire, lightning, earth, water, and wind.
Most people could only have one affinity, but fortunately, as a Uchiha, he was quite special, so he had many affinities. It wasn't everything, yet, it was good enough.
"Yin, Yang, Fire, Water, and Earth. That's your affinity."
After confirming Shinra's affinity with the chakra paper, Mikoto didn't feel surprised by the fire and yin affinity, as Shinra was a Uchiha, and all the Uchiha had a fire and yin affinity.
Yet, it surprised her to know that he also had a yang, a water, and an earth.
The earth aside, the yang and the water were surprising, Mikoto thought.
"Is it?"
"Yes."
"But, it doesn't really matter since the more, the better, right?"
"Well, that's true."
If possible, Shinra wanted to have affinity with all types of elements, but he knew that he couldn't be greedy, and at the same time, having more affinity wouldn't mean that he would become powerful. Instead of wasting his chances to rob others' meaningless talents, so he could gain all the affinity, it was better for him to think about how to gain the Eternal Manekyou Sharingan, so that way, he could use the "Eye of Usurp" infinitely, without being afraid of being turned into a blind person.
'So, who should I rob?'
Sasuke was definitely impossible since Shinra knew well that this guy was tied to a fate, and Indra's reincarnator, a piece that was set by the manipulator behind the world of Naruto.
If somehow Shinra used the "Eye of Usurp," he knew that he would be targeted by the one who manipulated the world of Naruto behind the scenes, the Sage of the Six Paths, Hagoromo Ootsuki.
More importantly, Shinra also didn't hate Sasuke, so he never thought to do anything to Sasuke, especially when he was in a relationship with Sasuke's mother.
Lastly, Sasuke also hadn't awakened his Sharigan, so it was meaningless for Shinra to steal anything from Sasuke.
If Shinra had to rob the "Eye of Usurp," the best person was Shishui, since as long as he robbed Shishui of everything, his eyes would become that Eternal Manekyou Sharingan, but unfortunately, he couldn't as he didn't have a chance, he was still weak, and he also hadn't awoken his Manekyou Sharingan at that time.
Still, to make the Eternal Manekyou Sharingan, he needed another pair of Manekyou Sharingan, and it was definitely far from easy to get those eyes, as those who had those powers were all powerful on their own.
Then again, all of those who owned those eyes were all shitty people, and when Shinra grew stronger, he wouldn't let them go.
"What jutsu can I learn?"
"The Uchiha have many fire jutsu, so you should learn fire jutsu. As for the other jutsu, it is limited."
"Fire, huh?"
Shinra didn't think that a fire jutsu was weak, especially when a certain most powerful character could destroy the entire ninja world of Naruto with just a fire jutsu, but if he learned a fire jutsu, could he have a similar effect to that person?
Naturally, no.
So—
"I want to learn the water, earth, and yin jutsu first, Mikoto-san."
"Okay."
Mikoto agreed, and like how she taught Shinra, he also taught her many things, including common sense, history, and those that she was interested in. Then, as expected, her mind was blown away, especially when this world wasn't ruled by a daimyo, and everyone, as long as they were powerful enough, had their fair chances to stand above many.
Whether they were the son of a butcher, a farmer, or even a beggar, as long as they worked hard, and were ruthless with themselves, and would do anything to change their fate, everything was possible, which was different from the world of Naruto, where everything was determined by their bloodline.
After all, in the world of Naruto, if one's parents were farmers, then they could only become farmers.
Naturally, for them, the members of the Uchiha could only become a ninja as it was their destined plan.
Mikoto could tell that Shinra's ambition was far stronger than a mere revenge; his eyes saw deeper, but no matter what, she would support him.
However, there was something that she had to tell him first.
"Shinra-kun, there is something that I want to tell you."
"Hmm? What is it?"
Mikoto blushed, becoming awkward, and subconsciously held her belly. It had been a while, and she was a little unsure, but as she had confirmed it, she wanted to tell the truth, but the bell of their home was pressed so many times as they heard Shion's cold voice.
"Shinra, go and prepare to fight! Teach someone a lesson for me!"
"Hmm?"

His first fight will start!
