When the Yin Seal imprint was completed, Kirito instantly felt the pressure on his body, which had hindered his ability to fully use chakra, disappear instantly. His chakra reserves skyrocketed as the full chakra within the Yin Seal began to output chakra with low power, feeding it back to Kirito, it's master, and increasing the normal amount of chakra in his body in a passive form.
The feedback brought by a Yin Seal that accumulates a small Tailed Beast-level Chakra was undoubtedly amazing. Even though it was just a little bit, Kirito felt that his chakra had been improved by two or three layers in disguise, reaching the level of a jounin-level Chakra without the yin seal.
He is probably half a Kakashi.
For a moment, Kirito felt his whole body was full of strength.
The Yin Seal is a secret technique developed by the Uzumaki Clan. Its main function is to save chakra. It is not the Seal of hundreds developed by Tsunade on the basis of the Yin Seal in the later stage. Therefore, it does not have the ability to instantly heal, strengthen attacks, and increase speed. Instead, it maintains youthfulness, improves body function, and keeps body function in full swing.
These were all the functions of the Yin Seal that Mito taught him.
Kirito estimated that the Seal of hundreds developed by Tsunade must have a certain relationship with her family's secret techniques, Senju power Fist and Palm healing Technique. The Seal of hundreds had multiple more functions.
"Yin seal, this brat actually mastered this sealing technique first, what a monster," Tsunade remarked, looking at the blue diamond-shaped mark on Kirito's forehead with admiration.
The difficulty of Yin Seal cultivation lies in possessing extremely strong chakra control power, which Tsunade already possessed. Now, she just needed to make up for the knowledge of sealing techniques.
Since stepping into the battlefield, Tsunade found that the amount of chakra she was proud of was far from enough to heal all her teammates. She remembered this sealing technique that can provide a large amount of chakra and had always wanted to practice it successfully. However, between fighting and daily use of the Palm Immortal Technique to heal her comrades' wounds, she had no time and enough chakra to practice the Yin Seal.
After finally returning to Konoha this time, she intended to learn this sealing technique.
However, she hadn't learned it yet, and a junior like Kirito had learned it before her.
But she wasn't jealous; she was just admiring and happy because her grandmother's sealing technique was being passed down to successors.
Konoha's descendants had preserved the knowledge of their ancestors well, just like the Will of Fire. This was a very happy thing.
"Mito-sensei, that's enough, stop now," Kirito said, noticing that he had successfully cultivated the Yin Seal, but Mito did not stop the chakra transfer.
"Have you succeeded? Let's practice another one, but this one can't be as big as the previous one," Mito suggested with a smile, looking at Kirito with bright eyes.
When Kirito heard Mito's words, he felt a shock in his heart. When he looked into Mito's eyes, he felt as if his secrets had been seen through.
Before he could speak, Mito said to the other people in the room, "You all go out. Let Kirito and me be alone for a while."
When the others heard Mito's words, Momoka's wanted to say something, but Mito only gave her a stare, and then she went out obediently.
Momoka, the Hokage consultant, was like this. What else could the others say? They all went out obediently and waited outside.
Nawaki still wanted to protest, but Tsunade took him out with one hand.
Once the others left the room, Mito casually set up a sealing barrier that could not be sensed from the outside world.
Seeing this, Kirito smiled wryly and said, "Teacher, when did you find out?"
The next moment, a head exactly the same as Kirito's grew out of Kirito's shoulder—it was a Zetsu clone.
"Hmph, I'm your teacher; you want to keep that little secret from me? You're a hundred years away from being able to do that," Mito glanced at the head on his shoulder proudly but didn't ask Kirito about zetsu's avatar.
She actually didn't know what the zetsu clone was; she just vaguely discovered that there was another person in Kirito's body by relying on the perception ability brought to her by Kyuubi. But she didn't expect it to be true. Her disciple was more than she imagined. His means were really not that simple.
That's good too—Konoha and The senju clan have him to protect them.
No matter how bad the situation is in the future, they won't get bullied.
She was very clear about the character of her disciple. He was someone who would never suffer. It was best for the Sandaime and Danzo not to provoke him; otherwise, there would be no good outcome.
If they goes overboard, people won't even be able to find their body
"Teacher, this is me..."
Mito didn't ask about the origin of Zetsu avatar, but Kirito didn't intend to continue to hide this mentor who had been so kind to him and wanted to explain the origin of the avatar.
Now that the zetsu's avatar had been discovered, there was actually nothing to hide.
He believed that Mito would not tell other people the secret of the zetsu avatar; otherwise, she would not have let the others out just now.
"Okay, I'm almost dead. I don't want to hear your little secret. Just know it yourself. Speed up. My chakra is less than before. The little fox in my body is getting restless again. my ears are a little tired now of its roaring."
Mito shook her head and said, not wanting to listen to Kirito's explanation.
Of course, the fewer people who knew about secrets, the better. She had no hobby of prying into other people's secrets. She just needed to know that Kirito would not harm her or the people in the village.
"Then let's forget about sending me chakra. You are so weak now, and if you lack enough chakra, you can't suppress the Nine-Tails," Kirito quickly persuaded.
"Don't worry; I educated that little fox when I just fell asleep. To broke away from the seal, It took a long time of accumulation. the seal was being eroded by its chakra. Now I have strengthening it back. It is fitted with a new chain, and no matter how hard the beast struggles for the time being, it will not be able to come out again," Mito said confidently.
Hearing this, Kirito said, "Sensei is indeed the most powerful sealing ninja in the world," decisively flattering her.
Mito accepted it calmly, with a happy expression on his face, and then said with a straight face: "Okay, stop flattering; quickly save up chakra and practice the Yin Seal. I will sleep for a while later, and I am a little tired."
Kirito immediately suppressed his smile, suppressed his tears, and closed his eyes again, concentrating on assisting the Zetsu avatar in practicing the Yin Seal.
There had been a successful process of practicing the Yin Seal once, so it was naturally easy to practice it again.
He quickly opened up a chakra pond constructed from Yin seals on his clone, which was much smaller than Kirito's main body.
And Mito's chakra was truly extraordinary—it must reach the Tailed Beast level, and she had a Yin seal, which also stored Tailed Beast-level chakra.
As long as Kirito no longer greedily created a Yin Seal Chakra Pond that could accumulate Tailed Beast Chakra and then quickly cultivated a Yin Seal for his Zetsu clone, it would not be a joke. He had complete confidence to do it.
About half an hour later, a blue Yin seal also appeared between the brows of his Zetsu's avatar.
"Kirito, please protect this child for me. We Konoha owe her too much," Mito said a little tiredly, then slowly closed his eyes and exhausted his last effort to concentrate on suppressing the Nine-Tails in his body.
"Yes, teacher, you can leave it to me with confidence. I will safely seal the Nine-Tails into Kushina's body. I will become Kushina's pillar and guard her until the moment I die," Kirito promised solemnly.
If it were before,. when the Yin Seal had not been cultivated successfully, he definitely would not have the confidence to make such a promise. But now it was different—his Yin Seal had been cultivated successfully, and even his Zetsu avatar also had a Yin Seal on his body.
With double Yin Seals accumulating chakra, he was now confident that he could temporarily suppress the Nine-Tails with his improved sealing chains using his own strength alone.
Adding the Sage Mode was also within reach.
This was the confidence brought by the last gift from his beloved teacher.
The third Hokage and the other two Hokage consultants undoubtedly attached great importance to the Kyuubi Jinchuriki. It took less than 10 minutes for the Kyuubi Chakra to leak from Mito, and they arrived one after another.
However, when they arrived, Mito was alone with Kirito.
They wanted to enter, but were blocked by Momoka's, unable to enter for a long time.
"What is happening here ? "
"Wait. Don't get in "
"Momoka, it's been almost 10 minutes. What are Mito-sama and Kirito doing inside? The Kyuubi is involved, and now is not the time for Mito-sama to be self-willed," Koharu's questioned Taohua, who was blocking her way.
"You have to make me say it a few times before you understand ? Mito-sama is helping Kirito practice the Yin Seal. Without her order, no one can go in and disturb them for the time being," Momoka replied forcefully, showing no respect to Koharu.
"You..." Koharu started to protest, but Mito's assistant, Mitokado hamura, held her shoulders and shook his head at her, signaling her to endure it.
Reluctantly, Koharu held her tongue, but she continued to mutter in a low voice, "Really, after such a big incident, how could that guy let Master Mito continue to fool around? What if Kyuubi accidentally breaks the seal? At that time, they should quickly reinforce the seal. That's more important than anything else..."
The ninja's hearing was very acute, so even though koharu's deliberately whispered, those around could still hear her.
It was evident that Koharu's actions were deliberate, aimed at criticizing Momoka and elevating herself.
However, the others around merely watched with cold eyes, remaining sober. No one questioned Mito's orders or stood up to support Koharu viewpoint.
"Hmph, this foolish woman thinks of herself as the most esteemed female ninja after Mito-sama. Mito-sama's influence in Konoha's internal affairs remains significant, even if she hasn't been actively involved for a long time," Momoka sneered inwardly at Koharu clumsy performance.
"Momoka, I heard that Kirito has successfully improved the Uzumaki Clan's unique sealing technique, Adamantine chains into the Titanium chain's, allowing anyone, not just members of the Uzumaki Clan, to learn it. Is this true?" Hiruzen asked Momoka suddenly.
Having arrived earlier, hiruzen had swiftly gathered information about the recent events. He likely understood what had transpired between Mito and Kirito while they were alone.
Momoka nodded in response to hiruzen question, smiling as she confirmed, "Yes, Master Mito tasked Kirito with mastering the Adamantine chains technique as his final assignment, and he has executed it perfectly."
This revelation surprised Hiruzen, as he had not expected Kirito to successfully improve such a powerful sealing technique.
In fact, the Uzumaki chains had been studied extensively by Konoha's sealing experts for some time, but none had managed to enhance it, not even Mito herself. Kirito's success was a breakthrough.
The Sandaime expressed his gratitude and admiration for Kirito's abilities, stating, "Konoha is truly blessed to have Kirito among its ranks. He is undoubtedly a genius."
Meanwhile, Kirito had used a special technique learned from a monk named Fayi, who hailed from the wind country's. Through this technique, which utilized both chakra and natural energy, Kirito found a substitute for the Uzumaki blood required by the original Adamantine chains.
This discovery allowed Kirito to successfully enhance the Adamantine chains, making it nearly as effective as the original version.
"How is she ? " After Kirito emerged from Mito's room, Momoka immediately inquired about Mito's condition, peering into the room to see that Mito had fallen asleep.
Kirito assured everyone that Mito was fine and that the Nine-Tails seal remained stable.
With a heavy heart, Kirito turned to the Sandaime, informing him of Mito's intention to prepare for the Nine-Tails inheritance ceremony.
"We need to get ready "
"It seem like we have no choice anymore. Leave it to me "
The Sandaime acknowledged Kirito's words and promptly began preparations, creating a shadow clone and sending it to issue various instructions.
Upon hearing Kirito's announcement, those who cared deeply for Mito, such as Momoka, Tsunade, Nawaki, and Kushina, couldn't help but feel sadness well up within them.
"Grandma..."
"Mito-sama.." Nawaki and Kushina even shed tears.
Despite his own sorrow, Kirito knew there were more pressing matters at hand. He approached Kushina and said, "Kushina, come with me. I have something important to discuss with you."
