"Nawaki-chan, I didn't ask you about this. Let me ask you again, when did Kirito learn how to create clones of himself?"

Mito held nawaki's head with her hands, exerting a bit of pressure, and asked him with a kindly smile.

to Nawaki eyes, it was anything but kind

He felt immense pressure as he tried to recall the information he needed.

Kirito buddy, you are on your own.

He decided to reveal everything without hesitation, even if it meant implicating his friend, Kirito. "Two weeks ago," he admitted.

Kirito had shared with him the trick of using Shadow Clones to accelerate his training.

This method involved bringing the memories and experiences of the clones back to the original upon their dispersal, effectively hastening the learning process.

Nawaki had found this approach to be highly effective, and he had managed to master several previously elusive ninjutsu.

In gratitude, he had passed on the Shadow Clone technique to Kirito.

As a technique made by his grand Uncle, he felt that it was within his rights to teach it to Kirito without consulting others.

Kirito, after learning the technique, had become even more dedicated to his studies. He would send three clones daily to engage in different activities: one conducted strange experiments in the basement of the orphanage, another came to Mito's to learn sealing techniques and utilized the library for research, while a third focused on practicing ninjutsu. The

original Kirito attended regular ninja school.

This rigorous routine was maintained diligently. Kirito's enthusiasm for learning far surpassed Nawaki's, driven by his unrelenting work ethic.

Every day, Kirito dispatched a multitude of clones to tackle various tasks, making the most of his time.

Nawaki, on the other hand, was less successful even with substantial chakra reserves. He was unable to match Kirito's boundless spirit and will to learn. Over a dozen clones were utilized daily to learn the art of Ninjutsu and engage in physical exercises.

Therefore, Nawaki was well aware of why Kirito's Shadow Clone had suddenly dispersed.

He was almost certain that the original body had been pushed to its limits and had likely collapsed from exhaustion.

Mito couldn't help but sigh when she heard Nawaki explanation. She placed a hand on her forehead, seemingly deep in thought.

She was aware of the Shadow Clone technique's side effects but hadn't expected Nawaki to teach it to Kirito.

"I was too careless. If that foolish Nawaki can use Shadow Clones to accelerate his training, Kirito couldn't possibly be unaware of it," Mito lamented, berating herself for not being a more responsible teacher.

Reflecting on the drawbacks and limitations of using the Shadow Clone technique for training, Mito felt a profound sense of remorse.

Mito, due to her deteriorating health and the increasing restlessness of the Kyuubi within her, spent most of her day resting. She had focused primarily on teaching sealing techniques to Nawaki, who required more attention due to his unpredictable nature. Despite her initial decision to accept Kirito as a disciple, she hadn't given him much personal attention.

Kirito, however, proved to be a bright and diligent child, quickly picking up on the lessons and requiring less supervision. This made Mito less concerned about his progress.

Unexpectedly, Kirito's rapid growth had also resulted in an unforeseen challenge.

"Momoka."

Mito's expression grew stern as she called out toward the door.

Instantly, a woman with a snake-like appearance named Senju Momoka appeared before Mito, immediately kneeling on one knee and lowering her head respectfully. She inquired, "Master Mito, please give me your instructions."

Momoka was an elite Jonin of the Senju clan and served as the captain of Mito's bodyguard.

"Retrieve Kirito and bring him back to me," Mito ordered.

"Understood."

With a swift nod, Momoka disappeared using the Body Flicker Technique to carry out Mito's directive.

...

When Kirito regained consciousness, he found himself in a familiar room. Though still groggy and exhausted, the memories from his shadow clone allowed him to piece together what had transpired and what he could expect.

His complexion soured as he cursed to himself, "That damned loli who used paralyzing poison on Senbon. Not only did it paralyze my body, but it also severely disrupted my chakra flow, causing my shadow clone to dissipate prematurely. The mental fatigue returning to my original body made me pass out from exhaustion."

As Kirito stirred awake, the door swung open, revealing Nawaki. He sported a bruised and swollen face, indicating that he had received a thorough beating from someone.

Kirito recognized the room instantly—it was the guest room at Nawaki's house where he had taken a nap before.

Nawaki wasted no time and asked, "What happened? Why did your shadow clone suddenly vanish?"

Kirito recounted the events truthfully.

"Grandma Mito is extremely upset this time. You better brace yourself for what's coming, hehehe~" Nawaki said with a wicked grin.

Brothers should share both joy and pain

Nothing personal, it just to vent the pain in my heart

The grin, however, quickly turned into a grimace of pain, as his facial injuries caused him to wince and tears formed in his eyes.

Kirito couldn't help but gulp as he noticed the bandages wrapped around Nawaki face. He remembered the terrifying fury of Mito when he had first entered the ninja school and how he had witnessed her rage while learning sealing techniques with Nawaki.

As he contemplated nawaki being beaten and left hanging from the ceiling with his head embedded in the ceiling itself, and the sight of him lying amid the rubble, Kirito realized that growing up with Mito as a teacher might not be as easy as he had initially thought.

Mito had a remarkable level of control over her power, allowing her to inflict severe pain without causing death.

Using the shadow clone to attend her class was a blatant act of disrespect. While it might have gone unnoticed, now that it had been discovered, punishment was inevitable.

Kirito was soon summoned to meet with Mito. The woman, despite her youthful and beautiful appearance, exuded an aura that made one feel as if the sun itself was dying.

To Kirito's surprise, Mito didn't appear angry this time, and her gaze held a different quality compared to usual.

Normally, Mito looked at everyone in the village with the same gentle eyes, with no special distinction. However, when her gaze fell upon Nawaki, there was an added kindness and anticipation, and she couldn't help but smile.

Kirito wasn't taken aback by this, nor did he feel jealous. It was only natural for Nawaki to receive Mito's love as her grandson. Kirito, at best, served as a tool to help Nawaki's progress.

He had realized this long ago and didn't expect or hope for more. He was grateful to Mito for her attentive teaching of the sealing technique, answering his questions in detail, and being a good teacher.

In return, he tried his best to excel in his role, encouraging and aiding Nawaki, and repaying her kindness in education.

This time, There will be no stepping on an explosif tag.

What a ridiculous death for Hashirama grandson

He bet madara had a good laugh out of it.

However, it seemed that something had changed now.

Mito was looking at him with a different expression, and there was a spread of delicious and beautifully presented food on the table, indicating that Mito wasn't angry but had actually invited him for a feast.

Kirito couldn't help but suspect if there was something weird about the food.

"Eat up, young one. These dishes are all prepared for you, so make sure not to leave anything behind," Mito said kindly.

Kirito couldn't help but wonder, "Is this some kind of super nasty prank?"

"Thank you, Mito-sensei. I won't hold back then," Kirito replied gratefully.

The food tasted delicious, and it wasn't a cruel prank. In fact, it had remarkable effects.

"Is this the famed medicated meal prepared by a medical ninja? It's rapidly replenishing my chakra and alleviating mental fatigue," Kirito marveled at the changes happening in his body.

"How is it? Does it taste good?" Mito inquired with a smile, observing Kirito's rosy complexion.

"Yes, it's incredibly delicious," Kirito replied sincerely.

"Then we'll dine together like this every day," Mito said as she served another bowl of rice to Kirito with her own hands, her smile unwavering.

Kirito was taken aback. "This may not be very convenient..."

Kirito initially wanted to decline Mito's invitation but stopped himself midway. He realized that Mito's expression didn't look so nice.

Forget about nice, It was effing scary

A man should choose his battle wisely.

"Little one, you can't skip class like you did today; it would make your teacher sad," Mito said with a smile.

As she spoke, she put her hand on Kirito's head.

He knew he will die if he refuse her.

He responded promptly, sitting up straight and nodding obediently. "Yes, Mito-sensei, I won't do it again,"

As a result, Kirito changed the way he split his time between his main body and shadow clones. The main body had to attend Mito's sealing technique lessons in person, and thanks to the daily intake of Mito's medicated food, there were no more instances of using three shadow clones simultaneously leading to physical exhaustion.

-------------------------------------

By the time Kirito left Nawaki's house, it was already nighttime. Thanks to the medicinal food that had effectively replenished his chakra and relieved his fatigue, he was now bursting with energy.

"Hey, Kirito, you've been studying sealing techniques with Mito-sama for so long today. Have you had dinner yet? Why don't you come over to my place for a meal? There's plenty to go around."

"Little Kirito, you seem to be in high spirits today. You usually look so tired. Make sure to get enough rest," 

"Kirito boy, I entrust my foolish child's education to you. Don't be concerned about my feelings. If he needs to be scolded or disciplined, go ahead. As long as his grades improve, I'll reward you with a powerful ninjutsu..."

Kirito strolled through the Senju clan's land, where many clan members greeted him warmly, offering sincere smiles.

Children, especially orphans like Kirito, were sensitive to the kindness and malice of others.

Kirito had a deep fondness for the Senju clan, as they were very pure and friendly. Once they learned that he was Mito's disciple and an orphan, they found ways to care for him, warming his heart.

In contrast to the Uchiha, who exuded cold and dark chakra, the people of the Senju clan radiated warm and sunny chakra, providing a sense of reassurance.

"What wonderful people. It's a shame that their numbers dwindled in this village," Kirito thought to himself.

He had pondered the disappearance of the Senju clan in Konoha's future. In later events of the series, only Tsunade remained active in the ninja world. Kirito contemplated this issue.

He had initially thought tha the Senju clan did it in response to the Second Hokage's order, willingly forsaking the Senju name to assimilate into Konoha.

However, upon direct contact with the Senju clan, Kirito realized that things were not as simple as they appeared.

The decline of the Senju clan was primarily due to the wars they had endured. The First and Second Hokage had brought great glory to the Senju clan, which became a source of immense pride for them, a legacy they felt compelled to protect at all costs.

However, after the deaths of the two Hokage, this legacy became a heavy burden for the Senju clan. They were determined to restore and safeguard this glory, and children of the Senju clan grew up under the shadow of these two great men, dreaming of becoming Hokage themselves.

As a result, they shed blood and sweat in the service of the village, always at the forefront of Konoha's defense. In both Ninja World Wars, the Senju clan was the mainstay of the Konoha ninja forces, often leading the charge.

In times of war, the Senju clan became a primary target for enemy forces who feared the possibility of another Senju Hashirama or Senju Tobirama emerging from their ranks.

Various factors had contributed to the deaths of many young adults and strong men from the Senju Clan during the wars.

Besides Mito and Tsunade, the Senju clan of today had very little combat strength left. Only a group of elderly and frail women and children remained.

In the original storyline, Mito passed away, Nawaki died young, Tsunade left the village due to her heartache, and the Senju clan had significantly declined, ultimately renouncing their surname and integrating fully into Konoha to shed the weight of their former glory.

Kirito pondered over how to prevent the demise of the Clan. He already had an answer in mind, but before that, he needed to attain sufficient power.

Half an hour later, Kirito returned to the orphanage, which had seen significant improvements. With an adequate economic foundation, a new building was constructed with various amenities such as slides, swings, and horizontal bars for the children's enjoyment. Kirito had his own house as well.

Upon his return, he greeted Nono and the others and then proceeded to his house.

From there, he descended to the basement entrance, where he had set up a seal to conceal and secure the area. This was a result of his ongoing training in sealing techniques under Mito's guidance.

Kirito's seal at the entrance was relatively low-level, but it served to prevent unauthorized access, especially by curious children.

"Kai "

He unlocked the seal with practiced ease, revealing a staircase leading underground.

As he descended into the basement, sensor lights illuminated the area. The basement contained three main categories of items: books, scrolls, and glassware.

The books consisted of topics related to medicine, electricity, and biology, which Kirito had purchased from a bookstore. Thanks to these books, he had gained knowledge in these fields, particularly biology.

The scrolls primarily contained ninjutsu, with an emphasis on sealing techniques. Thunder release and Yin release techniques were also included.

Kirito had acquired most of these techniques from Mito and Chizuru. While the collection of sealing techniques was from Mito, he had received many other ninjutsu through battles and connections with the senju clan.

The glass vessels in the basement contained various living organisms, including insects, plants, and even organs. Most notably, they contained numerous red hairs, all immersed in a green solution.

"Uzumaki blood is truly remarkable. Even a single strand of hair, when provided with nutrients, can regenerate and develop into flesh," Kirito remarked as he examined the fleshy tissue in one of the largest glass containers.

The tissue had started as a strand of Mito Uzumaki's hair that Kirito had secretly collected. After nearly a month of cultivation, it had undergone significant transformation, brimming with vitality and even producing chakra.

Chakra was the source of energy for all ninja arts, and Kirito believed that mastering powerful chakra was the key to becoming a formidable ninja. He envied individuals like Mito and Nawaki, who possessed naturally immense chakra, and he yearned for such power.

However, he was not born into the Uzumaki clan and lacked access to this potential. Therefore, he devised a plan to follow Orochimaru's example and integrate Uzumaki blood into his body through biotechnology.

The blood fusion 1.0 experiment was about to commence.

"Let's see if you can survive after being mixed with my blood," Kirito thought expectantly as he dripped his own blood into the glass container.
