He made a rough assessment.
His physical fitness and chakra, the secondary factors, had both more than tripled.
Most importantly, his eye power had increased more than tenfold!
He felt that the Mangekyō Sharingan was no longer far beyond his reach.
He glanced at the corner where he stored his nutrient solution. The last box was less than half full.
"I never expected this restoration process to consume so much!"
Seiichi made the nutrient solution himself because Soldier Pills tasted terrible.
There were two kinds of nutrient solution. One was for shinobi, with 10 milliliters per vial. The essence was in the concentration.
The other was for civilians, with 500 milliliters per bottle-plenty to fill a stomach.
Both came in a wide variety of flavors and were currently very popular on the market. This had also brought Fugaku's wealth back from the brink of bankruptcy to its former peak, and even beyond.
He drank the shinobi version. A single 10-milliliter vial could meet a person's physical needs for an entire day, along with providing various trace elements, keeping the user from going hungry without leaving them short of nutrients.
There were 100 vials in a box.
He had drunk seventeen boxes.
He would have to think of a solution. Ordinary Uchiha Clan members did not have the resources he did.
Forget becoming incredibly powerful-they might end up starving to death.
Ugh, what a headache!
Who knew the medicine working too well could be a problem!
Forget it. I'll deal with that later.
He had not been home in a long time, and Seiichi was afraid Mikoto would worry.
He hastily threw on a jacket and shuffled home in his shoes.
He needed to buy new clothes and shoes.
"Son, you... you... how did you end up like this?"
Mikoto stared at her son, who had grown so tall and muscular, looking somewhat dazed.
Had her son been away for seven years rather than seven days?!
"Mother, I succeeded!"
Good news ought to be shared right away!
Mikoto had a vague idea of what Seiichi was doing.
Now that she heard Seiichi say he had succeeded, she covered her mouth in delighted surprise.
"Really, Seiichi?"
Seeing Seiichi nod, Mikoto hurriedly sent someone to call Fugaku home.
When Fugaku returned and saw the enormous change in Seiichi's build, he could not help making a few guesses, and a hint of excitement appeared on his face.
Fugaku stationed guards outside the door and forbade anyone from disturbing them.
Then he took his wife, Mikoto, and his son, Seiichi, into the secret chamber in their home.
Not only that, Fugaku set up three barriers in succession to ensure their privacy.
"All right, Seiichi. Go ahead."
Seiichi nodded.
He told them both all his research results, as well as his findings and conjectures.
As Seiichi described everything, Fugaku and Mikoto gradually lost control of their expressions. Even their Sharingan activated involuntarily.
Countless thoughts ran through their minds.
By the time he finished speaking, they felt as though a lifetime had passed.
In that quiet secret chamber.
All three remained silent.
Only the strong, resounding beat of Seiichi's heart could be heard.
"Are you sure there aren't any problems?"
Fugaku's voice was inexplicably hoarse.
"I'm sure."
Seiichi nodded solemnly. This was no time for fooling around.
"Let's give it a try. Seiichi is our son."
Mikoto suddenly said something puzzling.
Though Seiichi remained expressionless, his pupils contracted almost imperceptibly.
Those words most likely meant exactly what he thought they did...
Fugaku said nothing in response.
But the three tomoe in his Sharingan began to spin, their speed steadily increasing.
In the end, only a blur remained. Then, in an instant, the three tomoe joined together, and their shape began to change.
When the Sharingan stopped spinning, a curved triangular shuriken shape accompanied by three small black dots appeared in Fugaku's Sharingan.
(I've made a slight adjustment to when Fugaku awakened his Mangekyō Sharingan here, moving it from the Third Shinobi World War to the Second Shinobi World War. Because the protagonist will take action later, some less important settings will be changed. For example, Fugaku, Shisui, and Itachi of the Uchiha Clan will not take the stage in the Third Shinobi World War.
Especially Itachi. The Third Shinobi World War broke out in Year 45 and ended before Year 48. Itachi was born in Year 43, making him five at the absolute most. Had everyone in Konoha died, or had everyone in the Uchiha Clan died, for them to send a child of around four-and the fucking only son of a prestigious clan's leader at that-onto the battlefield?! Was Kishimoto out of his mind?!)
"The Mangekyō Sharingan! Father, you really did awaken the Mangekyō Sharingan."
Seiichi's knowing expression surprised Fugaku and his wife somewhat.
"You guessed?"
"I've been reading the clan's records since I was little. I've read plenty of descriptions of the Mangekyō Sharingan.
"Mother told me stories about you when I was young, Father, so I had my suspicions. I just wasn't quite sure."
Seiichi's intellect had always been a source of pride for Fugaku and his wife.
So they did not doubt his words.
"But what finally confirmed it for me was discovering that the genetic defects in your blood were the fewest, Father-far fewer than in any other clan member.
"That meant your bloodline had evolved once. For the Uchiha Clan, there is no other evolution, only the Mangekyō Sharingan."
Fugaku nodded. So he knew. He had never intended to hide it from this son of his anyway.
"In that case, let's not waste any time."
Fugaku began steadily exerting pressure on Seiichi with his Mangekyō.
Neither father nor son used any abilities. It was purely a contest of eye power.
As time passed, Fugaku's astonishment continued to grow.
Finally, when he saw Seiichi raise his left hand, Fugaku raised his own left hand in acknowledgment, and both withdrew their eye power in unison.
"As expected, no matter what, the Three-Tomoe Sharingan still falls a little short of the Mangekyō Sharingan."
"No, you're wrong!"
Fugaku's words made Seiichi abruptly look up at him.
"I was already using ninety percent of my eye power just now. That means, in terms of eye power alone, your Sharingan has already reached the level of the Mangekyō Sharingan."
Fugaku's words stunned not only Seiichi but also Mikoto, who had been watching from the side, her eyes widening.
"My eye power has already reached the level of the Mangekyō Sharingan?!"
Hearing that, Seiichi checked with Fugaku again.
Fugaku showed no impatience and solemnly affirmed Seiichi's question once more.
Seiichi lowered his head and began muttering to himself, then abruptly stood up, his eyes growing brighter and brighter.
"Father, Mother. We were wrong, completely wrong. This is the truth!!!"
Fugaku and Mikoto exchanged a glance as they watched their son, whose behavior had become somewhat frenzied.
After a while, Seiichi finally calmed down and sat back down.
"Sorry, Father, Mother. I was a little rude just now."
Seiichi spoke with an excited expression.
"Father, judging from my own case, the evolution of the Sharingan with a complete bloodline has no Mangekyō Sharingan stage.
"Or rather, the Mangekyō Sharingan and Eternal Mangekyō Sharingan are actually the same stage.
"Because the Eternal Mangekyō Sharingan is simply a Mangekyō Sharingan without side effects."
