For the last seven days, Seimei had been going through a crazy grind at hell-level difficulty.
The first three days, which were Seimei's holidays, he went through two complete chakra infusion trading sessions under the supervision of his 'beloved' uncle, Senju Hashirama.
If that were all, it would still be fine.
But no, he also had to endure intense physical workouts and nearly bone-breaking Taijutsu training.
His Taijutsu sparring partner?
It was the God of Shinobi, Hashirama, himself.
Fortunately, although Hashirama was a bit of a goofball, he knew when to hold back to train the younger generations of ninjas.
Of course, even then, Seimei was still hit hard by his 'beloved' uncle's fists of love.
This guy's physical stats alone were off the charts. So, even though Hashirama held back a lot of his physical strength, Seimei still felt his bones creak and his internal organs shake with each exchange.
If it weren't for another special medicinal bath formula of Senju clan that relieved fatigue, mended muscle tears, and restored his health after an intense workout, he would have to resort to medical Ninjutsu to stay in top shape the very next day.
And after the holidays ended, Seimei had to endure Kamishiro Kirito's, his homeroom teacher's, training on top of Hashirama's Taijutsu lessons.
This was tough. Truly tough.
But Seimei didn't complain.
Because he could feel his Taijutsu skills progressing by leaps and bounds in those seven short days.
The combination of the system's proficiency upgrade panel and Senju Hashirama as an instructor was almost divine.
To put it simply, Seimei made more progress in his Taijutsu over these seven days with Hashirama than he did in seven weeks of his usual solo training.
His progress was practically visible to the naked eye, which made Hashirama even more excited, leading him to increase the physical and Taijutsu training difficulty by a notch.
But to Seimei, all this random stuff didn't matter right now.
Because today, Seimei felt like he could make a breakthrough to strengthen his physique.
His skin, muscles, tendons, and bones were brimming with infused chakra, ready to evolve to the next stage.
Just a little push, just one more chakra infusion session would be enough for him to break through his shackles and drastically improve the power of his physique.
So, he was eager to start the chakra infusion training session as soon as possible.
He had read about the benefits of the first major physique enhancement in the clan records. And now, it was about time to experience the very same thing himself.
-----
Konoha, Land of Fire, July 31st, Year 14 of the Konoha Calendar
Today was the eighth day since Seimei restarted his chakra infusion sessions after returning from the Kitakari town mission.
Seimei had already gone through three chakra infusion sessions in the last seven days, and today, he would start the fourth.
In the special training room, Seimei was quietly preparing the medicinal bath. His uncle, Senju Hashirama, was standing beside him.
Soon, Seimei stood up and said, "Okay. The medicinal bath solution is ready now."
Hashirama smiled and added, "Very well."
"It's about time you achieve your first major physique enhancement, building a solid physical foundation for the next major enhancements."
"I can already sense it."
"The cells of your skin, muscles, tendons, and bones have already been brimming with infused chakra, which pushed their current adaptation capability to their absolute limit."
"Now, they just need a little push."
"The gentle energy of the medicinal herbs and one more session of chakra infusion will force these cells to break through their limits, triggering a controlled evolution in a positive direction."
"This will make your bones stronger and muscles denser and more explosive, reducing lactic acid accumulation and muscle tissue fatigue."
"Your tendons and ligaments will become more flexible, and their tensile strength will increase several times, helping you move your body more flexibly."
"Naturally, your dexterity will improve, too."
"Finally, your skin will become more elastic and resilient."
"As for the deeper benefits and other factors, you will naturally see it with your own eyes and feel it yourself after you complete the first major physique enhancement."
Seimei listened to his uncle silently and slowly nodded his head.
He knew that his physique stat had reached the very limit before a major breakthrough.
According to his system's evaluation, his current physique stat was 19. So, if he could cross this threshold and reach 20, its effect on his physique would be more than just the deceptively simple and lackluster one point or 5% increase.
No. His physique will at least get a 100% enhancement. Afterwards, for every one point increase, his physique would probably improve by 20% to 30% per point until he reached another major threshold of 29 points.
Then, it would be time for another major upgrade.
But this is a talk for another time.
Right now, Seimei was completely focused on finishing the chakra infusion session.
He was excited, but he kept his composure.
Hashirama added, "Alright. Take off your clothes, get into the medical bath, and start infusing chakra into your skin, muscles, tendons, and bones."
Seimei didn't waste any time.
He discarded all his clothes except for his underwear and fully submerged his entire body into the medicinal solution, while keeping only his head out of the surface of the liquid.
Without further delay, he started extracting wisps of chakra from his chakra pathways and chakra points (tenketsu) before slowly merging them into his skin, muscles, tendons, and bones.
Soon, his entire body began to itch, and he began to feel a mild ache in every part of his body.
Fortunately, the medicinal liquid acted in time as its medicinal properties entered Seimei's body through his pores.
Its gentle energy soothed Seimei's aching body as the medicinal properties were constantly guiding the body cells to break through their limits and evolve as gently as possible.
The pain didn't completely go away. It was still there. But Seimei gritted his teeth and held on.
Time kept moving one second at a time. And in the blink of an eye, nearly two hours passed by.
Soon, Seimei noticed his body undergoing a tremendous change. And this wasn't subtle at all.
His body cells refused any more chakra infusion and began to mutate drastically.
His bone cells were becoming stronger, tougher, and began to gain unique shock absorption properties. The tensile strength of his ligaments and tendons kept increasing.
His muscle tissues were becoming denser and more tightly packed. The amount of energy stored within them started growing, and the muscle's burst power surged.
His skin cells also changed. They were coated in a natural layer of chakra on a microscopic level, causing Seimei's physical defense to surge several times.
The peripheral nerves, blood vessels, and chakra pathways also received a boost. However, he couldn't determine the extent of the boost they received.
Everything was going well. The only problem was the pain.
It was painful. Way too painful.
The pain of the rapid evolution of the physical body in real life was no joke.
He had been deceived by the novels and anime of his previous life, where the protagonist and other people made one breakthrough after another with a smile on their faces.
Who was the bastard who said that breaking through the physical limits would feel like receiving a comforting massage? What happened to the feeling of taking a relaxing, cold bath on a hot summer day?
Those novels deceived him.
Forget about receiving a comforting massage. Right now, all he was feeling was pain. It felt as if thousands of deadly, venomous ants were crawling inside his body and chewing his very being with their pincers.
I swear…
If I ever become strong enough to travel back to Earth, I would beat the shit out of these misleading bastards and let them feel the fraction of pain I am feeling right now.
Ouch…damn it.
Seimei, you have to hold on.
Pain is temporary, power is eternal.
Don't forget…
You are the great ancestor of the …ouch ouch!
Hisssss….
Why is the time flowing so slowly?
While Seimei was in the middle of cursing, his body continued to evolve.
And after a little over ten minutes, Seimei finally felt the pain subside.
Instead, he sensed the tremendous explosive power and terrifying potential of his current body.
He slowly clenched his fist again and again as if he were trying to feel power hidden in his muscles.
Soon, the pain he was feeling was completely gone.
And his whole body felt light, as if a huge burden was taken off his back.
He felt more alive. He felt like he was reborn.
Soon, the Otsutsuki bloodline's immense vitality and the remaining medicinal energy within the liquid healed his body completely.
He felt completely refreshed.
At this time, Hashirama's voice echoed in the room again.
"Congratulations, my dear nephew. You have achieved the first major physique enhancement."
