Nine-tailed chakra leaks naturally could not be hidden from the ninja in charge of defense outside, Kirito had just succeeded in suppressing the nine-tailed back again, a group of jōnin and some people Kirito knew who were proficient in the sealing art of sealing class ninja quickly arrived successively.
Some of the earliest arrivals also saw Kirito use the sealing technique - Adamantine Seal - Change to suppress the Nine Tails back.
"It's already fine, go back, you're not needed here for now."
Momo then exercised her right as Hokage's advisor and gave orders to the ninja who rushed over.
"Ha, if you need anything, please be sure to let us know first, we'll be standing guard outside."
A Sarutobi clan jōnin at the head of the group immediately responded and then left with the rest of the group.
However, some of the ninjas from the sealing class stayed behind, and they were taking out some sealing scrolls to seal the long-lasting Nine-Tailed Chakra in the room.
Kirito was also doing this kind of thing at this time, and he was much faster than the sealing class ninjas, directly using the chakra chains formed by the sealing technique - Adamantine Seal - Change to turn these Nine-Tailed Chakra, which were originally supposed to be intangible things, into something tangible as fast as he could pull them to Kirito's side.
In the end, the large amount of Nine-Tailed Chakra floating around in the room was collected by Kirito into a bottle covered with a large number of sealing jutsu, which he then put into an empty psychic card.
When the sealing class ninja in the room saw this, each of them eyed the chains of chakra released from Kirito's body.
They were knowledgeable and knew the power of this Chakra Chain.
Without a doubt, this was an offensive sealing technique that could not only possess the effect of binding chakra, but could also be used to whip people, thus disrupting the chakra in the enemy's body and preventing them from releasing their jutsu properly.
Sealing Jutsu - Adamantine Sealing Chain!
This name unanimously surfaced in their minds.
This powerful sealing technique that belonged uniquely to the Uzumaki clan was something that their sealing class had studied and had the relevant learning scrolls, but they hadn't seen anyone learn it in all these years.
However, the chains formed by the Adamantine Sealing Chain they remembered should be golden in color, completely different from the Chakra Chains Kirito was releasing at this time.
Obviously, this should be a new version formed by Kirito's modification of the Sealing Technique-Adamantine Sealing Chain.
And since Kirito wasn't a member of the Uzumaki clan like them, that meant that they had the same chance to learn this improved Sealing Jutsu-Adamantine Sealing Chain.
Worthy of being Lord Mito's favorite disciple, the most outstanding sealing art genius since the founding of Konoha, he had even managed to complete the improvement of this powerful sealing art.
"Kirito, is the sealing art you're using now is Adamantine Sealing Chain?"
Soon, an older sealing class ninja cheekily asked Kirito.
"That's right, it's a modified version that can be learned without the Uzumaki clan bloodline."
Since Kirito had used this improved sealing technique out, he anticipated the scene before him and said calmly.
"Then can you ..."
Hearing Kirito's affirmative answer, the older sealing class ninja immediately tried to say what he was really up to.
But before he could finish his words, he was interrupted by Kirito, only to see Kirito nod his head and say, "No problem, I will announce this sealing technique later, you can all learn it, but it requires two conditions, one is that you can't teach it privately, and you have to be implanted with the sealing technique by me, and the second is that you have to fully participate in the next Nine Tail inheritance."
"No problem."
The older sealing class ninja agreed without hesitation.
Kirito's conditions were not harsh at all and could be said to be very lenient.
The first condition would have been a matter of course, this improved Adamantine Sealing Chain was originally unique to Kirito, and his willingness to contribute it was already very rare, spreading it out would be impossible.
The second condition is also acceptable, these people were originally ordered by Sandaime to come here to carry out the matter of the nine tails inheritance and have long been ready to face the nine tails directly.
Overall, Kirito was simply giving them a precious sealing technique for nothing.
As the older sealing class ninja agreed, the other sealing class ninjas also agreed with vigor.
"Well, I'm here to thank you all on behalf of my teacher first."
Kirito said gratefully when he saw that all the Seal Class ninjas present had agreed to his terms.
The gratitude was genuine.
Only those who had directly faced the Nine Tails were deeply aware of how powerful the Nine Tails' power really was, once the Nine Tails broke free from the seal, these Seal Class ninjas who had taken part in the sealing of the Nine Tails would be the Nine Tails' primary target of attack, and would face a huge threat, and a single slip up would be the end of their lives.
These people risked so much to come here, Kirito felt that this improved Adamantine Sealing Chain to them is not a big deal, if they can learn, it can at least increase the security of the sealing of the nine tails a few points.
There is strength in numbers.
The original plot did not explain in detail the process of Konoha's success of the Nine Tail Jinchuuriki, but after he personally felt the power of the Nine Tails, he thought that this process is not so easy to achieve, and the Konoha should have paid a small price to succeed in sealing the Nine Tails once again.
This is known when you think about the Nine Tail Rebellion in the original plot.
The current Konoha is not as weak as it was after the 3rd Shinobi World War, but it definitely won't be easy to seal the Nine Tails.
Moreover, Mito's current condition was just too weak, and it was unknown how much of a role she would be able to play in sealing the Nine Tails.
In that case, he needed more manpower to learn Adamantine Sealing Chain, a sealing technique that could effectively trap the Nine Tails.
Kirito took out a Summoning Scroll card from his body and used the Summoning technique - Release to take out a Scroll from it, and then summoned the Sealing Chain to come over and began to teach them the improved version of Adamantine Sealing Chain hand in hand.
The sealing class ninjas here were all elites in the sealing class, with solid knowledge of the basics of sealing arts, and with a little guidance from Kirito, their learning speed increased by leaps and bounds.
Suddenly, Nawaki ran over and interrupted Kirito's teaching process, he said to Kirito, "Kirito, Grandma is awake, she's calling you over."
Hearing Nawaki's words, Kirito immediately stopped teaching and quickly walked over to Mito.
"I'm coming, sensei."
Kirito held one of Mito's hands with both of his and said softly.
"Kirito, you've done a great job, you've completed all the final subjects, you'll have to put in more effort in sealing the Nine Tails next."
Mito used his other hand to touch Kirito's head and said with relief.
"Sensei, I've just seen the power of the Nine Tails, with my current ability, I'm afraid I won't be able to subdue it."
Kirito said with a bit of a headache as he sniffed.
This is the big truth, with his current strength in the hands of the Nine Tails to escape is probably no problem, but subdue it that is as difficult as heaven.
"Don't worry, I'm here, how far have you practiced your Yin Seal?"
Mito said calmly.
It was true that her current physical condition was terrible, but it was still possible to make one more effort before dying.
"At the rate I'm accumulating chakra now, it's still about half a year away from completion, I think."
Kirito answered truthfully.
The cultivation of the Yin Seal, he had started a year ago.
However, the process of accumulating chakra was destined to be a time-consuming and laborious matter, and even if he had the White Zetsu clone, a rechargeable treasure that could quickly restore chakra, he still couldn't complete it in a short period of time.
Not to mention that he was probably much more daring than both Tsunade and Haruno Sakura.
In order to be able to cultivate the Sage Mode successfully, the pool of chakra that he had opened up in his body with the Yin Seal was huge, reaching the extreme level of his chakra manipulation, and if he completed the buildup, the amount of chakra in his Yin Seal was estimated to be at the level of a Tailed Beast.
That's right, the Yin Seal, a powerful sealing technique, was an important piece of the puzzle for him to learn the Sage Mode without completing his bloodline fusion experiment.
"Your appetite is still as big as ever, that's it, before I leave, let me help you out."
Mito smiled as he heard Kirito's reply and flicked Kirito's forehead with his finger.
As soon as the words left his mouth, before Kirito could react, a large and warm chakra passed along Mito's hand that was holding his.
"Be quiet, and focus on receiving it."
Seeing this, Kirito wanted to speak out to stop it, but was interrupted by Mito's voice.
Kirito looked at Mito's familiar kind expression at this moment and couldn't help but burst into hot tears, he immediately closed his eyes to keep the tears from flowing out, and then focused on accepting the chakra that Mito was passing over, and continuously channeled this chakra into the pool of chakra that he had opened up with the Yin Seal.
For a while, a small rain of chakra rained down over the pool of chakra opened up by the Yin Seal in Kirito's body.
Drops of blue chakra rain continued to drip down into the chakra pool, quickly filling up the pool whose water level was only two-thirds of the pool's height.
Not long after, a blue diamond-shaped seal appeared on Kirito's brow.
The Yin Seal was successfully cultivated!
