Ever since obtaining the Naruto template, Adam had frequently chatted and communicated with Kurama.
His primary goal was to borrow Kurama's power, offering the condition that Kurama could occasionally come out for some fresh air.
What did Kurama desire most?
Freedom, of course.
Naruto's side would never allow Kurama to break free from the Eight Trigrams Sealing Style and roam around. In fact, to prevent Kurama from influencing Naruto further, Konoha even assigned Yamato, who could use Wood Release, to constantly accompany Naruto and help suppress Kurama's power.
But Adam's situation was different. Adam promised to open the Eight Trigrams Sealing Style at regular intervals, letting Kurama out for an hour of free activity.
This was because, once the Eight Trigrams Sealing Style was opened, it would revert to its original state during the next load.
Adam had also experimented to verify this, by slightly tearing open the Eight Trigrams Sealing Style to let some of Kurama's power leak out.
The result was that the Eight Trigrams Sealing Style became perfectly intact again during the next load.
Kurama fully participated in the experiment, so when it was inside Naruto, it continuously worked on Naruto's Eight Trigrams Sealing Style, slowly prying it open with its Chakra, hoping to gain freedom one day.
But when it came to Adam, it simply gave up, knowing that prying it open was useless anyway.
That was until Adam discussed the matter of letting it out for fresh air.
"Four months is too long, kid. I lent you all my power to assist you in battle.
Three weeks, no less!"
"Kurama, you need to know how many years you've been confined.
You only came out once, it seems, when Naruto was born, and you were controlled by a member of the Uchiha clan, and soon after, you were sealed away. I can let you out for an hour, a full hour.
During that hour, as long as you don't kill anyone or cause destruction, you can do whatever you want. That's the taste of freedom.
Two months, letting you out once every two months, that's already my bottom line!"
Adam replied with conviction.
Kurama paced back and forth in its cell, falling into a state of indecision.
It yearned for freedom so much, staying in a cramped cell every day, transferring from one Jinchuriki to another.
It didn't know how long it would take to break the Eight Trigrams Sealing Style on Naruto's side, and it truly wanted to run freely outside.
Finally, it seemed to have made a decision, clutching the bars of its cell with both paws and saying:
"Once a month, I'll agree right now if it's once a month!"
"Deal!"
Adam immediately grinned and nodded.
Actually, if Kurama had insisted, he would have accepted once every three weeks. After all, it was only an hour each time.
"Uh..."
Hearing Adam agree so readily, Kurama froze for a moment, a hint of regret stirring within him. Perhaps if he had insisted a little longer, three weeks might not have been impossible.
However, as the proud Kurama, it would not be as dishonest as humans. Since it had agreed, it naturally would not go back on its word.
Actually, there was another very important reason why it was willing to cooperate with Adam, besides being able to get out of its cage for fresh air.
It was that it didn't feel any hatred, fear, or disgust towards it from Adam, which gave it a slightly different feeling towards Adam.
Over a thousand years, it had suffered through war, hatred, and betrayal, almost becoming a collective of hatred, so it was most sensitive to human malice.
"Then let's begin!"
Adam walked to the sealed cell door, reached out to grasp the seal, and then activated all his mental power, gradually peeling it open.
The Eight Trigrams Sealing Style was a top-tier Sealing Technique developed by the Fourth Hokage based on the principles of the Four Symbols Sealing Style, capable of firmly sealing the powerful Kurama within Naruto's body.
It was almost impossible to undo the Eight Trigrams Sealing Style from the inside, but it was much easier from the outside.
Adam did not know Sealing Technique, but he could use his powerful mental strength, in conjunction with Kurama inside, to forcibly tear open the Eight Trigrams Sealing Style little by little.
"Just a little more!"
As most of the sealing paper on the door was peeled off, the Sealing Technique on Adam's stomach also gradually disintegrated like ink.
However, just as Adam was about to completely unveil the Eight Trigrams Sealing Style, a hand suddenly appeared and grabbed him.
"Naruto, you can't!"
Adam turned his head to see a man with the same golden hair as Naruto, wearing a jacket with "Fourth Hokage" written on it, appearing beside him.
"I almost forgot, besides half of Kurama and the Eight Trigrams Sealing Style, there's also Minato and Kushina's Chakra inside Naruto."
When Minato sealed half of Kurama inside Naruto, he also sealed a portion of his own and Kushina's Chakra inside Naruto.
Once Naruto's Eight Trigrams Sealing Style was about to be broken by Kurama, he would appear to reinforce the Eight Trigrams Sealing Style, preventing Kurama from escaping.
Similarly, once Naruto's mind was about to be completely taken over by Kurama, Kushina's Chakra would also awaken, using the Adamantine Sealing Chains, unique to the Uzumaki clan, to help Naruto subdue Kurama.
"Um… I'm sorry, I'm not your son Naruto. Naruto's Eight Trigrams Sealing Style is perfectly intact. I need Kurama's help right now. We can chat again another time!"
Pushing Minato aside, Adam directly tore open the Eight Trigrams Sealing Style.
Minato, however, was confused by Adam's reply. Not Naruto? How could Kurama be inside him? Why was his Eight Trigrams Sealing Style also there? And what did it mean that Naruto's Eight Trigrams Sealing Style was perfectly intact?
"Kurama, lend me your power!"
The Eight Trigrams Sealing Style was completely torn open, and the door was also opened. Adam raised his fist towards Kurama.
And Kurama also raised its paw and touched Adam's fist:
"Adam, remember your promise, once a month!"
"What exactly is going on here?"
Minato, standing beside him, was also utterly bewildered.
Meanwhile, on the outside, looking at the metallic torrent Magneto was shooting at him, Adam let out a loud shout, and a massive amount of Kurama's Chakra immediately surged into his body.
The fatigue from fighting Apocalypse earlier vanished, and his body surface rapidly changed, instantly being covered by Kurama's massive Chakra, transforming into a Kurama avatar seventy meters tall.
"Hold it!"
Nine giant fox tails quickly extended from behind him, forming a defense in front, blocking all of Magneto's metallic torrent.
"Devour my Tailed Beast Ball!"
Opening his mouth, a black Tailed Beast Ball with a diameter of over ten meters rapidly formed.
The Tailed Beast Ball is the Tailed Beasts' most destructive move, the ultimate expression of Chakra form transformation. One shot can blast apart a mountain.
And as the strongest Tailed Beast, even with only half of its power, Kurama's Tailed Beast Ball was far more powerful than those of other Tailed Beasts.
Crucially, because Kurama's Chakra was so immense, many people believed it had infinite Chakra, so if it wanted to, its Tailed Beast Ball could be fired consecutively.
"Boom!"
The powerful Tailed Beast Ball collided with the metallic torrent, which was immediately shattered into Diffindo.
