Konoha, Land of Fire, June 12th, Year 14 of the Konoha Calendar
Today was Sunday, a rare free day in Seimei's life as he had no academy classes, no mission, or any other commitment.
What? Did you say that the Ninja Academy's first semester usually starts in August?
Well, Seimei thought that, too.
Usually, students of the Ninja Academies had their June and July months off before beginning their next academic year's first semester in August.
However, after the third-year S-class evaluations were done, the Academy, like a ruthless corporate boss, took away its 60-day holiday.
As a result, instead of August, the S-class students of the Central Ninja Academy had to attend the first semester of the fourth academic year at the beginning of June after just a short one-week break.
These S-class teachers became increasingly unreasonable with each passing day.
The training, academic courses, and combat lessons intensified even more. And if that wasn't enough, the students also had to drag their already exhausted bodies to complete two missions of at least C-rank every month.
Of course, many students also use these missions to slack off a bit. Not much. Just one or two days per mission.
Even if each mission had a relatively longer deadline of seven days, the students didn't dare to think about slacking off more than one or two days per mission.
Why?
Because if they were caught, their demonic teachers might just intensify their individual training even more.
Never mind.
People should be honest and diligent.
Anyway, Seimei had already completed his first mission, and today was Sunday, so he was free to explore a new technique of the Senju clan right now.
It wasn't anything fancy. It wasn't a Jutsu. It wouldn't even increase his strength in the short term.
It was a special training method.
But if he practiced it diligently, he could accelerate the development of his physique. In the long term, he could become stronger, faster, and sturdier. His already enhanced reflexes and regeneration capabilities would experience a massive boost.
This was the training method that made the Senju clan ninjas' already strong physiques even more monstrous.
And what did a consistent improvement to an already ridiculously powerful physique give you?
Chakra.
An enormous amount of chakra.
No wonder every adult Senju had such a large chakra capacity, regardless of their bloodline purity and innate talent.
They had an almost cheat-level training method.
It was the Senju clan's secret Chakra Infusion Training Method that was perfected by countless generations of Senju Shinobi.
The core principle of this technique was quite simple.
You had to slowly extract chakra from your own chakra network and gently infuse it into the cells of your entire body.
That included your skin, muscles, tendons, bones, nerve receptors, and even sensory and internal organs.
The slow but steady infusion of chakra would make these body parts stronger and better over time.
Their bodies and combat senses would slowly become more powerful than an average Shinobi who had never gone through the chakra infusion method.
Of course, the process was far from simple.
One mistake, and you could suffer from serious muscle, bone, or internal damage.
That was why this technique had to be practiced under the guidance and watch of a veteran Senju Shinobi.
And today, the one who would be teaching the chakra infusion technique to Seimei and supervising his training was none other than his uncle—The God of Shinobi, Senju Hashirama.
With him by his side and his mastery over medical Ninjutsu, Seimei wasn't worried about being seriously harmed.
Even if he messed up, got injured, and ended up coughing blood, Hashirama would fix him up within a few minutes.
But he didn't want to make such mistakes, though, because the resulting pain would be undeniably real.
Who would want that unless someone had a masochistic tendency?
Certainly not him.
He was not some overly enthusiastic snake uncle.
But it didn't matter now.
Why?
That was because Hashirama was standing in front of him, and he was about to talk about the chakra infusion technique.
On the other side, Hashirama held his chin with his left hand while staring at the ceiling of the room.
His expression indicated that he was thinking deeply about something right now.
Then, he crossed his arms, tilted his head slightly to the side, and looked at Seimei.
After a while, he clapped his hands with an enlightened expression on his face. The whole reaction and gesture were so exaggerated that people would think his uncle had finally found the path to nirvana.
A few seconds later, Hashirama asked, "You read the scroll on the chakra infusion technique, right, Seimei?"
Seimei stared at his uncle's antics blankly before replying, "Yes."
Hashirama smiled and said, "Perfect."
"You see, Seimei. Although the underlying principle behind the chakra infusion technique is simple, the technique is incredibly difficult to execute."
"You need great control over your chakra."
"If you lose control of your chakra during the infusion process, it can lead to serious cell or tissue damage."
"Recklessness could leave you crippled for the rest of your life."
"Of course, I'm talking about the ninjas who don't belong to the Senju or Uzumaki clan, or those who don't possess overflowing vitality."
Seimei nodded as he kept listening.
"Now, other ninja clans also have their own specialized chakra infusion training method."
"However, since most ninja don't have as much chakra, healing capability, and innate chakra control capabilities as the Senju, their application of this technique is limited to specific organs."
"Let's take the Inuzuka clan as an example."
"Their chakra infusion technique focuses on strengthening their nose, ear, and the sensory organs related to them to enhance their hearing and smelling capabilities."
"They also infuse chakra into their leg muscles to make themselves faster than many ordinary ninja clans without a proper chakra infusion technique."
"Then, we have the Akimichi clan."
"Their chakra has an innate Yang attribute. So, they infuse their chakra in their fat-storing glands, their skins, and their bodies."
"It helps them store fat and expand their bodies safely without suffering from typical health issues and muscle tears."
Hashirama paused for a bit and then explained with a smile.
"But we don't have those restrictions."
"Our bountiful chakra, superior chakra control, and powerful physique with innate regeneration capabilities meant we could afford to be a little reckless."
"We infuse chakra into our entire body. And I truly mean Entire Body."
"We infuse chakra into our entire body's skin, muscles, and bones to make our body sturdier, stronger, and faster."
"Your physical strength will increase. Your agility will be off the charts. Your physical defense will be as tough as a rock."
"We infuse chakra into our nerves to make our reflexes lightning fast."
"We infuse chakra into our eyes and optic nerves to improve dynamic vision and eyesight."
"We infuse chakra into our skin, ears, tongue, and other sensory organs to push our innate sensory capabilities to the limit."
"You will also infuse chakra into your bone marrow, blood, heart, and every other internal organ in your body to improve your regeneration capabilities, digestion, energy storage per cell, and your overall survivability."
"You won't just improve one or two aspects of your body, but your entire physique."
"Your blood, body, and your entire body will become more attuned to chakra and natural elements. Your chakra capacity will increase at an accelerated rate."
"Your innate physical shackles will be shattered."
"It will bring you nothing short of a complete evolution of your potential as a Shinobi."

Additional Thoughts: Hehe...I'm back, guys. Well, I still have to keep my right eye closed for like ten more days. But the pain in the eye is already gone. It's just the recovery time now. Hopefully, I would no longer be the one-eyed king after these ten days passed. The eye-to-hand coordination with one eye really sucks!
