Yuuji made a decision. He wanted to resurrect Iroha with Impure World Reincarnation and then continue to experiment on Iroha.
Like implanting Hashirama cell on Madara's body, Yuuji didn't mind going this route if necessary.
Right now, only Iroha was suitable for human experiments. He could not do anything to the Hyuga Clan and secretly kidnap Hyuga's clansmen.
So...
"Iroha, you have disappointed me, but it doesn't matter. I will find a way to let you succeed."
Yuuji planned to use Impure World Reincarnation and dig out Iroha's right eye at the same time.
At this time.
"Wait, wait a minute, Yuuji-sama, I think I can still be saved..."
Iroha said with a soft voice.
The vital signs that were constantly declining were now stable at a low level as if they had achieved a balance.
Yuuji stopped what he was doing.
Kabuto, who was going to pick up a prisoner, also turned around with a surprised look.
"Did you survive? Well done, Iroha."
Yuuji praised and looked at Iroha.
Iroha's body was still trembling slightly, trying to adapt to this new organ that was so powerful that it was unimaginable.
Every heartbeat seemed to drive his whole body to jump.
"How do you feel?" Kabuto's eyes sparkled.
"It feels very strange. It feels like there is a powerful power source in my body... and it brings me even stronger power..." Iroha opened his right eye and observed his own changes.
Every time his heart beat, it would burst forth with more power, pushing forward the flow of blood even faster.
"If you refine the chakra now, there should be a burst of growth... Has there been any change to Byakugan?" Yuuji asked.
"Byakugan, there is a slight swelling feeling. It seems to have become more active, and the eye power has also increased a bit." Iroha murmured in a low voice.
Yuuji pondered for a moment and nodded slightly.
Next was all kinds of tedious tests.
They tested the changes in the body in all directions, as well as the changes in Byakugan.
From the physical test to the efficiency of chakra extraction, and finally to Byakugan's long-range vision and perspective observation...
All kinds of abilities welcomed a wave of rising.
As time went on, Iroha's strength would improve further.
What really caught Yuuji's attention was the change in Byakugan.
"Byakugan's eye power has indeed increased a bit. The test for Byakugan has to be carried out regularly. I want to get the most comprehensive data. After you adapt to this heart, immediately start the transplant of other internal organs, and finally the bone marrow transplant, so that you can have Otsutsuki's blood-making ability."
What Yuuji wanted to do was to transform Iroha step by step into an artificial Otsutsuki.
"After Toneri transplanted Byakugan, he can upgrade Byakugan to Tenseigan. I hope Iroha can also do this."
There was a trace of expectation in Yuuji's calm eyes.
This Tenseigan was the true supreme Bloodline Limit of the Otsutsuki clan, unlike Rinnegan who needed to fuse with God Tree's bloodline to possess it.
According to Yuuji's own calculations, even the Tenseigan in the Otsutsuki clan should still be an incomparably precious treasure.
Kaguya, Isshiki, Momoshiki, Kinshiki, Urashiki, Hamura, none of these people had been able to awaken Tenseigan.
Momoshiki still had to rely on eating his younger brother to open the third Rinnegan, using the power of the three Rinnegan in his body to match up with the new ninja world F2, and he himself had not been able to open Tenseigan.
"Tenseigan..." Yuuji looked meaningfully at Iroha's right eye.
Could it succeed?
He did not expect Iroha to succeed in the end, but at the very least, he had to let him see that this path was feasible. He had to slowly turn Iroha into Otsutsuki. As long as he could continuously increase Byakugan's level, it would be enough.
If it was really necessary...
This kind of high-purity Byakugan...
Yuuji pondered.
"Iroha, from now on, I allow you to not appear as a Root ninja.
If you want to, you can use the identity of a Hyuga to walk in the village." Yuuji ordered.
Iroha, who was feeling Byakugan, was stunned, and then he nodded expressionlessly.
Anyway, there was no difference to him.
'Moreover, restore the identity of as a Hyuga? What is the meaning of Yuuji-sama doing this? Moreover, transplanting Otsutsuki's organ can improve Byakugan's eye power...'
Iroha touched his chest. His strong heart was beating.
He tried hard to think about whether this was a new mission.
Not long after.
Iroha slowly took off his mask in front of the mirror. He felt a little strange about his face.
Root ninjas did not have the past or the future. They only lived for missions and silently provided nutrients for Konoha.
Subconsciously, Iroha focused his gaze on the lines on his forehead.
Caged Bird Cursed Seal.
He stared for a while, picked up a Konoha forehead protector, and put it on his forehead, covering the shameful and sad mark.
After that, Iroha walked out of the secret base with a cold expression on his face.
After several years, he once again revealed his face and walked on the streets of Konoha.
It had been more than three years since the Battle of Kikyo Pass.
Konohagakure which can often see outsiders coming here was recovering its vitality at a speed visible to the naked eye.
Under Fourth Hokage's rule, this village was developing on a good side, and the loss of power was also recovering quickly.
"Konohagakure... These ignorant villagers have no idea how precious all of this is."
Iroha's expression was indifferent, without any change in his emotions.
Wherever he passed, the cold aura emitted from his body made the passers-by shrink back and carefully avoid him.
Iroha naturally successfully attracted the attention of some people.
"This guy is a little strange. He is wearing a Konoha forehead protector and his left eye is closed..."
"Did he lose an eye in the war? And it is Byakugan?"
"I remember now. No wonder he looks familiar. Isn't this guy Iroha? After graduation a few years ago, there has been no news of Iroha!"
"What a cold feeling. This guy is like a piece of ice. I understand now. He has joined Root."
Some people of the younger generation immediately rushed over and looked at the person in front of them in surprise.
After all, Hyuga's eyes were unique.
"Iroha, are you Iroha? In school, you are also called a genius. I haven't seen you for a long time."
Kurenai's eyes lit up and she immediately went up to greet him.
"Kurenai? You are already an excellent ninja." Iroha paused and said with a numb expression.
It was clearly congratulations, but there was no warmth in his words.
Many people immediately understood and confirmed that this guy had joined Root.
Kurenai was about to walk over.
But Genma appeared at the first moment and stopped her with a solemn face, "Don't worry, Kurenai. I won't let this guy hurt you."
"...?"
"..."
"Genma, you are making things difficult for us." Ebisu covered his face.
Ibiki glanced at Genma, "This guy, I don't know what stimulated him. He tried his best to pick up girls. Although it seems inexplicable many times, he did what we wanted to do but were afraid to do."
Kurenai was stunned and rebuked, "What are you doing? He is Iroha, not an enemy. Besides, didn't you publicly announce a few days ago that you wanted to protect Sister Yugao"
Genma frowned and said seriously, "Kurenai, the first time I saw you, I felt that you were different from other girls. You were more gentle and needed my protection. As for the matter between me and Yugao, I was afraid that you would be angry, so I didn't tell you. I didn't expect you to already know."
Genma reached out and grabbed Kurenai's small hand.
Then, Kurenai slapped him to the ground and raised her foot to kick him.
Screams filled the entire street, attracting the attention of countless people.
Iroha looked at the scene in front of him with an indifferent expression. He did not show any expression. His gaze toward the crowd also revealed a strong sense of distance, as if he was observing some endangered animal.
"Although I don't quite understand, I saw a male dog make a request to mate with a monkey. However, it was rejected. This is generally the case."
After Iroha finished speaking, he raised his foot and left, not having any desire to talk to these people of the same period.
"You bastard, it doesn't matter if you don't know how to speak or shut your mouth. Have you not learned how to speak in Root for the past few years?"
Genma stood up with a swollen face, sneered at him, and slowly rolled up his sleeves.
Both of them listened to Yuuji's orders, and Genma thought that the mission to strengthen the clan was much more important than the mission that Iroha had received.
"Wait, Genma, he is a ninja of Root!"
"Root ninjas have no feelings..."
The others' expressions changed slightly, and they were about to stop him.
Iroha slowly turned his head.
At this moment, his right eye slightly widened, and Byakugan's eye power instantly burst out and landed on Genma.
Genma's heart jumped, and his movements suddenly stopped. He helplessly watched Iroha slowly walk away.
"This guy, Iroha... what exactly is going on? That eye power just now gave me a very uncomfortable feeling."
Genma looked at Iroha's back in bewilderment.
He was not attacked, nor was he subjected to genjutsu. It was common knowledge that Byakugan could not cast genjutsu like Sharingan.
But the pressure that appeared and disappeared in an instant was real...
"What is going on with this guy? He lost a left eye, but he has an even stronger right eye?" Genma was suspicious.
Ibiki said lightly, "I remember that Yuuji once snatched back a Hyuga clan main house Byakugan from Kirigakure on the battlefield. At that time, this matter become a topic of gossip for a period of time, but it was left unsettled for a long time. There was no more movement from the Hyuga clan, could it be..."
Everyone was deep in thought.
They all remembered.
Could it be... that the main house Byakugan had been transplanted onto Iroha?
...
Iroha returned to the Hyuga clan grounds.
This attracted the shocked gazes of some Hyuga clansmen.
"Hey, isn't this guy..."
"That's right, Iroha. A clansman that first to join Root!"
"He actually came back. What's going on? Could he have retired from Root?"
"Don't joke around. How could there be a saying of retirement in a place like Root? Even if Danzo died, the person who took over Root wouldn't be easy to talk to!"
Some of the clansmen had already reported to Hiashi and the elders of the Hyuga Clan.
Soon, the entire Hyuga Clan was alarmed.
It was because Iroha's identity was too special. Not only was he a Root ninja and represent Yuuji, but also because...
His right eye was transplanted with the main house's eye
This has set a precedent for the entire Hyuga clan with an extremely bad nature!
Very quickly, Iroha, who had returned home, received an order from the clan to participate in the clan meeting and receive questions from the clan head and elders.
Iroha went.
"Iroha, are you returning this time to carry out a mission?" An elder asked directly.
"If returning to the clan itself is a mission, then it is indeed," Iroha replied indifferently.
The branch house head, Hizashi, knelt down with a gentle expression and said, "No matter what, you are welcome back. If Yuuji-sama needs our Hyuga clan to cooperate, please tell us. We will help if we can."
The higher-ups of the Hyuga Clan nodded.
If they couldn't beat him, they would lie down. Their Hyuga clan knew the way to survive very well.
In the face of others, Hyuga can be conceited, but in the face of Yuuji's extraordinary strength, and he was already a high-level existence in the village, the Hyuga Clan was very sensible.
Back when Yuuji was only Danzo's student, they didn't dare to push him too far in order to take back the Hyuga main house Byakugan. In the end, they could only compromise and watch as Yuuji transplanted this Byakugan to Iroha.
Now... they didn't expect that Yuuji would actually let Iroha go.
Everyone, whether it was the branch house or the main house, unconsciously stared at Iroha's right eye.
Their expressions were all different.
This was a new path that had opened up for the Hyuga Clan.
The eyes of the main house member had been placed on the members of the branch house...
"Wait!"
Hizashi's expression changed.
Even more people noticed that something was wrong.
"The deterrence of this eye... why is it so strong!"
"The original owner of this eye was not talented. It was far from being able to dig out Byakugan's potential, let alone develop it to such an extent. But why was Iroha able to push this eye to such a level..."
"I remember very clearly. A few years ago, when Yuuji brought Iroha to our clan to pressure us, this eye was still very ordinary!"
Waves of shock rose in many people's hearts.
Why was it like this?
Just what kind of change had happened to this Byakugan that caused his eye power to rise to this level, surpassing most of the Hyuga's Byakugan?
While many people were shocked and longing in their hearts, they felt even more uneasy.
If Iroha had done it himself, then it would be even more terrifying. This meant that those with outstanding talent from the branch house would be able to maximize the strength of the main house Byakugan after seizing their Byakugan.
Of course, it could also be that Shiranui Yuuji had helped Iroha increase his eye power, but this kind of thing... could even strengthen Byakugan? Just what kind of secret did he grasp?
"Everyone, if there is nothing else, I will be going back. Let me know when the clan has a mission."
Iroha's left eye was tightly closed, and his left eyelid had caved in.
The right eye slowly opened, making people frown.
He turned and walked out of the meeting room.
This kind of rude action, no one was in the mood to blame.
"His eyes, his eyes... Did he advance to Mangekyo Byakugan?!"
Hoheto, who was guarding outside the venue, looked at Iroha's right eye. His eyes suddenly widened, his body trembled, and he was extremely excited.
Jealousy surged out like an explosion, gnawing at his heart.
The Otsutsuki was killed by Yuuji, and then Iroha returned to the clan. The eye power of his right eye was increased, and if there was no connection between them, Hoheto would gouge out his own eyes!
"Beyond the eyes of ordinary Byakugan, it is true! Our clan pays too much attention to Caged Bird Cursed Seal. Byakugan's potential has been locked down by too many people, and the number of people in the main house is too small, which makes it possible for our clan to break through Byakugan's limit!"
Hoheto thought of the Uchiha Clan. This clan did not create a Caged Bird Cursed Seal to deal with its own clan. As long as they could open Sharingan, they would be valued.
Now, Fugaku and Kazue had broken Sharingan's limit.
"Is Caged Bird Cursed Seal a mistake in itself?"
Hoheto clenched his fists, his breathing rapid, and his eyes filled with ambition.
He remembered the conversation he had with the Otsutsuki clansmen that day. He knew a lot of secrets.
Hoheto touched his forehead.
"There is a high chance that Iroha has not broken through Caged Bird Cursed Seal. This technique has bound the Hyuga Clan for thousands of years. It is not so easy to break it. But if he can't break it using the Root power. How can I get rid of this shackle... Or should I think of a way to get the scroll that records Caged Bird Cursed Seal?"
