Naruto: The Age of Ninja Swords Begins in Kumogakure

Having successfully obtained the batch of reproductive cells, Tamura Hao placed them in a specially made culture chamber before setting off for Konoha once again.

That's right, he has developed an embryo culture device that can be separated from the mother's body. This is due to his sufficient technological accumulation and the pure life force of Grell energy.

Especially the latter. With Grell energy, even a pig could handle it, let alone someone like him who's a cheater.

Although he didn't know how Shin Uchiha would develop cloning technology in the future, Tamura Hiroshi was very confident in what he had done.

He went to Konoha for one person.

After sensing the surroundings to make sure everything was alright, Tamura Hao used his transformation technique, took out a bouquet of flowers he had prepared beforehand, and went to the cemetery outside Konoha Village.

"As expected, it's here."

Looking at the white broom-shaped hairpin to his side, Tamura Hao smiled with satisfaction.

That was Kakashi Hatake, the target of his trip. The reason he expected Kakashi to come here today was because it was the anniversary of Obito Uchiha's death.

Given the bromance between Kakashi Hatake and Obito Uchiha, even when they were on missions, they would carefully plan their return to visit their best friend as soon as possible.

This was also when Kakashi Hatake was least alert, as the other's attention was focused on the tombstone and the memories.

Looking around and seeing that there weren't many people nearby, Tamura Hao used Magnet Release to control a syringe to fly silently over, and then suddenly stabbed it into Kakashi's neck, injecting the super-strong anesthetic inside.

The moment Kakashi felt the pain in his neck, he reacted and reached out to pull out the needle, but it was too late.

Just as he was about to raise his hand to form a hand seal, someone suddenly appeared beside him and grabbed his hand.

"Kakashi, let's have a youthful showdown! This time, I'll carry you around the village a thousand times. I'm sure I can surpass your record from last time."

Tamura shouted enthusiastically, then hoisted Kakashi onto his back and ran out of the cemetery at lightning speed.

Some people saw the two figures, but didn't pay much attention.

The two often competed in all sorts of bizarre ways in the village, and the villagers were already used to it.

However, Kakashi's mind became increasingly muddled, and he realized that this was not Guy. The smell on his body was wrong; it didn't have the sweaty smell of Guy's frequent high-intensity training.

Ultimately, unable to resist the effects of the drug, he fell into a coma. When he woke up, he found himself lying in a room and immediately touched his eyes.

As an elite ninja, Kakashi did not panic. He even naturally looked around and found that it was a bedroom, simply furnished but cozy.

Finally, his gaze fell on the bedside table, where several files were placed, with familiar names written on the side. The format of the files made Kakashi's heart skip a beat.

That was the village's file format, and it was even a relatively old-fashioned one, a version from more than ten years ago.

After thinking for a moment, he picked up the file on top with his father's name on it and began to look through it. He found that it was indeed his father's file, which was very detailed, especially the records for a certain period of time, including who he had contacted and what he had said. It was obviously the result of surveillance.

That period of time was just before my father committed suicide. At the end, there were also records of conversations between several important figures, which I remember very clearly.

Upon seeing the conversation records of those people, Kakashi Hatake clenched his fists, and a surge of anger and murderous intent rose in his heart.

Suppressing his anger, he picked up the second file, which belonged to his teacher, Minato Namikaze.

It didn't seem like much at first glance, but he found a very detailed autopsy record at the very end.

In other words, someone dug up the teacher's body and dissected it. How dare they do that?

The next document was from the teacher's wife, and this one contained even more information, almost like surveillance. There was also an anatomical record at the end, and even research records on the placenta.

The following files were also very detailed, all of which were about people close to him, and the last one was about himself.

After seeing these, Kakashi Hatake's anger disappeared, but his eyes became incredibly cold and menacing, filled with an intense killing intent.

It took him a while to finally suppress his emotions and regain his indifference. He got out of bed, opened the window and looked at the scenery outside. He found that he was on an island surrounded by an endless sea.

"Kirigakure! Ringo!"

Upon seeing the Mist Concealment headbands and the Ringo family crest on some people, Kakashi Hatake frowned slightly. He then looked at a hand-drawn, simplified route map in his hand, compared it with the surrounding environment, and quickly located a building with a metallic sheen.

After thinking for a moment, he jumped out of the window and headed towards the marked building.

The people here seemed to have received instructions; they didn't stop me from going over, they just looked at me curiously.

Kakashi flipped the paper over to find a simplified floor plan on the back. He entered the building, went up the stairs, and quickly arrived at the top floor.

It was a huge laboratory, filled with various instruments and equipment, and a tall young man was busy working on something.

Kakashi walked over and sniffed, smelling a familiar scent—the smell of shampoo, the same as the one who had knocked him unconscious and carried him away. Clearly, this was the person who had brought him here.

"Did you replace my Sharingan?"

He asked directly, revealing that he now possessed not just one Sharingan, but a pair. He had even checked through a piece of glass on the way here and confirmed that it was a single-tomoe Sharingan, not the three-tomoe one he had before, which had been replaced by the other party.

"Yes, it's over there."

While busy working, Tamura Hao pointed to a lump of flesh soaking in a nutrient tank next to him. Kakashi walked over and discovered that there was a small human face on the other side of the lump of flesh, with an eye in the left eye socket. However, it was not the three-tomoe jade he was familiar with, but a complex pattern.

"kaleidoscope?"

Recalling a legend about the Uchiha clan, Kakashi guessed that this might be a Mangekyou Sharingan.

While continuing his work, Tamura Hao explained, "I discovered that when I was examining you. The power within your eye is far stronger than that of a normal three-tomoe Sharingan."

Afterwards, they extracted and cultured the cells, and attempted to cast a forbidden spell that could summon the souls of the dead from the netherworld, but failed.

There are only two possibilities for this outcome: either the other person's soul has been sealed by a forbidden technique such as the Corpse Demon Sealing Technique, or the other person's soul is not in the Yellow Springs Pure Land, meaning the person is still alive.

I checked earlier, and there was only a set of clothes in that grave; there was no corpse.

"Obito!"

Kakashi understood; it meant that Obito might not be dead.

If Obito didn't die, why didn't he come back to find us?

"Is it because of Lin?"

Kakashi quickly thought of another teammate and realized it might be because of that incident.

After all, Obito's feelings for Rin were very deep, so Rin's death must have been a greater blow to him.

After finishing his work, Tamura Hao turned around and began to earnestly deceive people.

"There was something strange about what happened with Nohara Rin back then. The Third Mizukage ordered Nohara Rin to be sealed in a Konoha Chunin, intending to use this to bring the Three-Tails into the village and release it to cause damage. Then our elites would launch a surprise attack from the outside, and we would break through Konoha from the inside and outside."

The plan sounds feasible, but there are differences between the tailed beasts. The Three-Tails is relatively weak, especially on land away from water. It can be sealed with a suitable sealing technique. With Konoha's resources, it wouldn't take long to deal with the Three-Tails. Therefore, the plan was destined to fail.

Many people in the village opposed it at the time, but the Third Mizukage insisted on doing so.

The plan ultimately failed; not only was the Three-Tails killed, but none of the accompanying elite team members survived.

I was quite puzzled before, but after seeing that eye and learning about the relationship between the three of you, I suspect there must be a mastermind behind all of this.

"You should know that the Sharingan of the Uchiha clan needs to be awakened by strong emotional stimulation, and then improved. The Mangekyou Sharingan is the same, but it requires even stronger emotional stimulation, such as the death of a loved one."

Perhaps your eye was activated at that time, which means that Obito Uchiha was also present at the time, and it was he who went berserk and killed everyone there.

Therefore, we in Kirigakure are not the masterminds behind the deaths of your teammates; we are also victims, and in this respect, we share a common enemy.

"Furthermore, I want to compete to become the Fourth Mizukage. The current Third Mizukage and others are my enemies, and I will definitely eliminate them in the future. Don't you want to participate?"

"You want to recruit me?"

Kakashi was silent for a while before asking, realizing that all this talk, including the files he had shown earlier, was to persuade him, to win him over, and to make him betray Konoha and join Kirigakure.

"As the son of White Fang and the strongest genius in Konoha's history, you are qualified for me to recruit you. However, I didn't expect there to be an unexpected surprise."

As he spoke, Tamura Hao handed over a Misty Hidden headband that he had prepared beforehand. He really wanted to recruit this future Konoha technician, the teacher of the two main characters.

"You are very well prepared."

After thinking for a moment, Kakashi took the headband from the other person and put it on his head.

The other party was so well-prepared that he couldn't find an excuse to refuse.

After reviewing those files, he could no longer return to the village; otherwise, he feared he might not have been able to suppress his murderous intent and would have taken action against those people.

It's a pity that I'm not strong enough, otherwise I could have wiped them all out.

Moreover, he no longer had many ties to the village, except for Kai. However, there were still files on Kai and his father, Might Guy, and the last part of the file recorded some shady things.

He guessed that this person would probably also be eyeing Akai.

"What did you do to my body?"

I put on my headband, and this time I didn't cover my eyes.

Previously, even with only one Sharingan activated, he couldn't handle it and had to rely on the seal placed on his forehead to temporarily suppress the eye. Now, however, he feels very relaxed despite having both Sharingan.

Although there is a big difference between a one-tomoe Sharingan and a three-tomoe Sharingan, this is a complete pair. In addition, he can clearly feel the difference within himself.

Very different.

"Come with me."

Tamura Hiroshi stood up, gestured, and walked to another part of the laboratory.

The laboratory on the top floor belongs to him alone and is divided into two parts: one half for biological research and the other half for ninja tool research. The modification of Kakashi's body was carried out in the biological research section.

Kakashi glanced at the fleshy blob with Obito's eye embedded in it, and followed the person toward the laboratory.

Tamura Hiroshi arrived at a pre-prepared projector, turned it on, and played the video of his previous modifications of Kakashi on the screen, fast-forwarding it tenfold.

The video is played while narrated.

"You are almost seventeen years old this year, and your body is basically formed, especially your height, which has reached 1.81 meters. Based on the study of your joints, it has been determined that you will not grow any taller, so I have modified your bones."

"Through the Kaguya clan's Shikotsumyaku (Corpse Bone Pulse) technique, a titanium alloy framework was created around your bone cells to enhance your bone strength. At the same time, a chakra core made from Shikotsumyaku cells was implanted. You can convert Shikotsumyaku chakra through that core to further strengthen your bones..."

At this point, Tamura Hao picked up a picture and handed it to Kakashi; it was a picture of alloy bone cells taken under a microscope.

"It is somewhat similar to plant cells."

Kakashi saw that picture and made an analogy to the cell wall of a plant cell.

Because of Rin Nohara, he also read some medical information and learned about the differences between animal cells and plant cells. Now, this bone cell is surrounded by a layer similar to the cell wall of a plant cell.

"It does have something to do with plants, because our use of the Corpse Bone Pulse incorporates some of the Wood Release power of the First Hokage of Konoha, which makes the resulting bone cell structure more reasonable and robust."

Tamura Hao nodded. Indeed, the First Hokage's Wood Release technique was used in this aspect. In fact, after the First Hokage's body was activated by soaking it in Grell energy, it was also integrated into the Bone Demon's body, further perfecting the Corpse Bone Pulse.

"That is the crystallization of life force, sealed inside the Death Gate of your heart. It can continuously emit high-purity life force to nourish your entire body, effectively assisting in physical cultivation, and providing super-strong self-healing abilities during combat..."

When the video plays down to the heart modification, the essence and effects of that surgical modification will be explained further.

"The chakra core transplanted next to your heart was made from the Uchiha flesh and blood of your current eyes, and it also incorporated tissue cultivated from Obito's eye cells, as well as the cells of the First Hokage."

"Your chakra, after being transformed by that chakra core, can perfectly supply your current Sharingan, and even using Obito Uchiha's eye later will be much easier..."

"You're going to give me Obito's eyes again?"

Kakashi Hatake was puzzled, not understanding what this person was doing.

"That eye isn't that useful, and it was given to you by Obito Uchiha. You are someone he acknowledges, and only you can use that eye; otherwise, he will take it back."

I enhanced that eye with a chakra core cultivated from his cells and Hashirama cells; it has already awakened the Mangekyou Sharingan. I will seal it into the Ea sword afterward.

That eye technique's effect is to distort and tear space, and it will also give that sword the power to tear space.

Furthermore, it can activate the Sage Mode power within Hashirama's cells, enabling Sage Mode to fuse with Sage Chakra and further amplify the power of his eye techniques.

Tamura Hao didn't have much interest in the eye itself; what he was eyeing was the Kamui space that the eye connected to.

Previously, the sealing technique, along with the Amber Purification Bottle, was used to collect the Kamui space and seal it inside the Amber Purification Bottle for future use. Now, only the offensive Kamui that shattered space remains.

Directly transplanting it onto Kakashi would definitely cripple him, so he used it as the core to create a ninja tool.

The design was inspired by the Eajuu Sword from the Fate/stay night game, specifically by Gold Pikachu.

Of course, its power is far inferior to that of others, but it is quite qualified as a ninja tool.

Furthermore, with the chakra core created by fusing Obito's cells and Hashirama's cells as a carrier, it can repair the damage caused by use, making it almost as easy to use as Obito Uchiha with no side effects.

Not to mention he also sealed in a large piece of Grell Stone to aid in its nurturing.

"Is that the ninja tool you were just making?"

Kakashi thought of the thing that had just been made, a uniquely designed ninja tool, or rather, a sword.

"Yes, I used the Uchiha clan's transcription seal to imprint the eye techniques onto the three cylinders on the blade of the Ea. Rotating the cylinders will activate the eye techniques to distort space, and rotating all three together will increase the power by more than three times."

Similarly, the consumption will increase threefold, and from now on, that Ea sword will be your weapon.

Tamura Hao had a high opinion of that sword, after all, it was a weapon capable of shattering space, and during the Fourth Shinobi World War, even the arm of the Gedo Mazo was broken by Kamui.

Of course, he left some arrangements inside and made a psychic contract, making himself the ultimate controller of the Ea sword.

"Of course, that Ea sword is too powerful and consumes too much energy, so it's not suitable for regular combat. That's why I forged another weapon for you."

"That spear from just now?"

Kakashi thought of the spear that had just been placed on the platform.

"That's called Thunder Spear. It has special lightning release power that can amplify your lightning release ninjutsu."

Tamura Hao nodded. It was a chakra core he had specially prepared for Kakashi, made by sealing the corpse of the Third Raikage, which could unleash that kind of black lightning release.

Its design is inspired by the Thunder Spear used by Perfect World No. 10, with blades on both ends.

"Why not a knife?"

Kakashi felt that using a sword was better, as he used to practice with swords. Although he hadn't used it since his father's broken sword, his best weapon was still the ninja sword.

"Because the spear is more suitable for using the Chidori ninjutsu. Also, your identity needs to be kept secret from now on, and you need to change your appearance. You just need to take off your mask and dye your hair, and you shouldn't be easily recognized."

Furthermore, that Thunder Spear incorporates fragments of the White Fang Ninja Sword; you should be able to wield it perfectly.

"A fragment of that knife?"

Kakashi was stunned. He had kept the fragments of that sword sealed at home, but they were completely destroyed by the Tailed Beast Ball that the Nine-Tails unleashed. How did the fragments end up in this person's hands?

"We happened to be on a mission in the heart of the Land of Fire when the Nine-Tails was causing trouble. We heard the commotion and went to retrieve some items."

Tamura Hao readily admitted that he had been to Konoha, and after seeing the change in Kakashi's eyes, he offered an explanation.

"The Nine-Tails' breakthrough had nothing to do with us, and I didn't have the Mangekyou Sharingan to control the Nine-Tails at the time."

"The Mangekyou Sharingan... so it really is an Uchiha?"

Kakashi thought of the Uchiha clan; if we're talking about the Mangekyou Sharingan, it seems to be the Uchiha.

"This document might lead you to the person who released the Nine-Tails."

Tamura Hiroshi took out a document and handed it over; this was one of the harvests from the Root Base.

Kakashi glanced at the person with suspicion, then took the file bag and took out the documents inside. They were investigation records of the Nine-Tails' rampage, including information that Minato-sensei had revealed before his death.

"A one-eyed kaleidoscope!"

Looking at the information his teacher revealed before his death, and the kaleidoscope pattern drawn on it, Kakashi's eyes turned even blood redder, and he even gained an extra tomoe, evolving from a single tomoe to a double tomoe.

"Obito? How could it be Obito? How could he possibly try to harm our teacher?"

Although reason tells me that this should be true, I just can't believe that the culprit who caused the Nine-Tails' chaos was Obito, who also killed my teacher and his wife.

How could Obito have become like that?
