Eight Trigrams Seal
"Partial Tailed Beast Transformation?"
Shuichi looked at Naruto's change and thought to himself.
This state appears a moderate number of times in the original work. Jiraiya said that the Nine-Tails Chakra would burn and tear Naruto's skin, and its powerful healing ability would damage the Jinchuriki's body and even shorten his lifespan.
Killer B to have any problems using it, except that it consumed a lot of stamina. Shuichi couldn't make a detailed judgment on how it felt, since he wasn't Jinchuriki.
"The quality of the chakra has increased significantly, which may be due to the special properties of the Nine-Tails," Shuichi silently assessed.
Once transformed, Naruto was no longer in control; the Genjutsu Barrier was completely ineffective and no longer needed.
To Kakashi's astonishment, the appearance of the Four-Tails Naruto brought an instant calm.
Then several tails hooked back on its head, and it raised its head and opened its mouth, with black and white chakra converging in the center until it was compressed into an ultra-high density dark sphere.
"Tailed Beast Ball? This humanoid form... how is that possible?" Kakashi asked in disbelief.
But what happened next was even more unexpected: the dark chakra sphere suddenly shrank dramatically, its density almost bursting out of control.
Naruto, however, swallowed it whole, causing his entire body to swell into a giant, fat ball, looking both comical and ferocious.
"What? Oh no..."
Boom!
A terrifying energy cannon suddenly erupted, and a small black dot could be vaguely seen heading straight for Shuichi.
The impact along the way completely overturned the nearby ground, and the released chakra frantically compressed the air, forming a super-powerful shockwave tens of meters high.
"Hehe, it looks quite cute, no wonder it's Nine-Tails fox."
Ice Release: Ice Rock Ancient City!
Shuichi slapped the ground with one hand, and a gigantic, crystalline city, tens of meters in length, width, and height, rose up.
The next second, it collided with the mutated Tailed Beast Ball, boom--
The deafening explosion echoed through the forest, reaching even Konoha several kilometers away, causing many ninjas to immediately look over in alarm.
Others attempted to explore in that direction, but were stopped by the Anbu at the edge of the village. "The Lord Hokage has ordered that no one is to proceed to the area at the two o'clock position today."
"Everyone, there's no need to worry. This is just a secret experiment arranged by the village. If there's nothing else, please return to your posts as soon as possible."
Near the Forest of Death, the Anbu) also intervened and calmed the numerous ninjas, preventing anyone from going there to cause trouble on their own.
Back on the field, Kakashi watched the smoke and dust dissipate, somewhat numbly.
Two-thirds of that ice crystal city was gone, leaving only a giant spherical crater in the middle; it had almost been completely destroyed.
He had witnessed Shuichi's Ice Release defensive power firsthand. With such Tailed Beast Bomb, he had absolutely no way to deal with it, and even Kamui couldn't absorb it at all!
"Is this the power of the strongest Tailed Beast? Even with only half of the Nine- Nine-Tails in its Four-Tails form, it's already this powerful..."
While he remained silent, Shuichi vanished completely. Sensing that his target was no longer behind the Ice Wall, the crimson fox was about to search for him...
Suddenly, the ground nearby trembled violently, and several thick wooden stakes surrounded Naruto, while several wooden hands reached out and pressed down on him.
Wood Release: Wood Style: Deep Forest Emergence!
Roar...
Naruto's berserk body tried to break free of the restraints, but he only had time to struggle before his chakra was suppressed.
The deep infrared glow gradually faded, revealing a comatose boy with flushed skin, who appeared to be temporarily unconscious.
Swish...
Shuichi appeared out of nowhere in front of him, grabbing his clothes with one hand and pressing down on Naruto's head with the other.
Seeing that the situation had calmed down, Kakashi quickly jumped to Shuichi's side and asked, "Is it over?"
"No, the first phase of the test is just to let you see the hidden power of your future subordinates." Shuichi chuckled. "You should step back a bit. Sealing is a delicate task; I need to control it carefully..."
After Kakashi retreated a distance, Shuichi formed several hand seals in quick succession, and nine enormous ice pillars appeared out of thin air, forming a circle around him.
Similar to the Kumogakure's suppression of the Tailed Beast' power, Turtle Island Sacred Land, he could accomplish the same feat single-handedly using Yin-Yang Release.
Wow!
With the changing scenes, Shuichi has awakened the Sharingan and stolen other people's souls, could easily enter the spiritual world.
Beep beep beep...
In the dimly lit space, every step felt like walking on water.
Shuichi moved unhurriedly, and soon arrived in front of a huge cage. Looking at the pitch blackness before him, a slight smile appeared on his lips.
Snap!
The cage bars trembled, vertical pupils lit up from the darkness, and the enormous fox head slammed into the sealed door. "It's you? A Wood Release user, how did you manage to get in here..."
"It seems you don't have a deep impression on me. Well, it's been over a decade since we last met," Shuichi said calmly.
"You can now call me the Fifth Hokage. I've come in today to have a talk."
"It's the Hokage again! They're all damned!" Nine-Tails roared furiously, "So you're that brat from back then, you despicable bastard..."
Seeing its frantic cursing, Shuichi realized that verbal persuasion might not be effective, since it wasn't his area of expertise.
"Senior Minato, I've figured out the seal you left behind. Even without the key, I can handle both breaking it and resealing it on my own."
Shuichi ignored Nine-Tails and calmly declared, "Naruto has only just Jonin; he has a long way to go before he can control Nine-Tails Chakra."
"Now that I am the Hokage, I do not want other villagers to sacrifice themselves because of the Jinchuriki's loss of control."
Furthermore, once Naruto goes berserk and kills his comrades, he will never trust this power again. Therefore, I hope you can understand my actions today.
"Save that remaining chakra for when you and your son reunite later. If you agree, you don't need to resist the suppression later."
Having said that, Shuichi leaped up and tore open the seal.
At the same time, the person outside pulled up Naruto's shirt and unleashed the sealing technique directly into his stomach.
Since it's not a perfectly matching key, there are bound to be places where Yang Release Chakra violently blasted open.
Crack! The seal on the Nine-Tails was completely broken.
In Kakashi's eyes, Naruto's body was merely emanating Chakra Cloak once more; he had no idea that the Lord Hokage had actually shattered the seal.
It's easy to imagine how powerful Shuichi's suppression is now; he single-handedly blocked Nine-Tails from escaping, and the little chakra Minato left behind was simply not enough to stop him.
The strongest Hokage in history is no joke!
Perhaps knowing this, the Fourth Hokage did not appear.
The Nine-Tails... was so surprised by the suddenness of the surprise that it paused for a moment before reacting. It immediately lunged forward and smashed open the sealing gate, bang!
"Roar! You arrogant bastard, die!"
The Nine-Tails's massive body charged rapidly toward the tiny human, and angrily slammed down with one claw—thud!
The ground was deserted. Shuichi had somehow appeared in the air, with Sage Mode markings on his face, and a spinning windmill with a diameter of more than ten meters in his hand was ready.
Buzzing--
Sage Art: Wind Release: Sage Art: Wind Release: Super Tailed Beast Rasenshuriken!
Bass!
The Wind Blade sliced through space like lightning, striking the Nine-Tails directly in the chest and exploding, instantly unleashing a blindingly terrifying Wind Ball that blasted it to the ground.
Roar!
Countless tiny wind needles pierced the Nine-Tails' body, causing it to scream in pain. Its eyes bulged with bloodshot veins, and its chakra, filled with hatred, immediately swept through the entire space.
Glug glug...
Seeing Nine-Tails) charging up its Tailed Beast Ball again, Shuichi was speechless. Couldn't they come up with something new? It's always the same claws and balls; I'm so tired of it!
Even the Eight-Tails can spray ink and stuff, and other Tailed Beast can use ninjutsu, but the strongest Nine-Tails doesn't seem to know much...
Shuichi didn't want to strain himself any longer; at his speed, he wouldn't give it time to slowly prepare its chakra.
Whoosh... A Senbon flew to the Nine-Tails's side, and the next moment a figure flashed out.
A colossal, pale sphere had materialized in his hand, larger than the two heads of the Nine-Tails. Crackling with electricity, it pressed down on his upper body with terrifying energy—BOOM!
Sage Art · Lightning Release · Sage Art: Lightning Release: Great Ball Rasengan!
This unparalleled attack lifted the Nine-Tails' entire body, and the powerful impact sent it flying back into its sealed cage. It crashed sideways to the ground, tumbling several times, its entire body a mess, clearly suffering serious injuries.
In all these millennia, I've never suffered such humiliation! But before it could even get up, Shuichi hands and unleashed Sage Art Technique Ice Release - Ice Style: Ice Dragon Jutsu!
With a whoosh, several thick, crystalline Ice Crystal Dragon, like pythons, swarmed towards the Nine-Tails, immobilizing it in just a few breaths.
"This is... the power of the Sage of Six Paths?" Nine-Tails struggled desperately, but couldn't get up at all.
After careful perception, it realized that this Yin-Yang Release was somewhat similar to, slightly different from the power of the Six Paths, but essentially from the same source.
Who exactly are you?
"I already said it once, I am the Fifth Hokage of Konoha." Shuichi slowly walked over. "Now, I finally have time to speak properly."
"This action is merely to warn you of some things. The Rinnegan has already appeared, and the information about the Demonic Statue of the Outer Path is completely confirmed. If nothing unexpected happens, the target is none other than you Tailed Beast."
"In the future, when Naruto encounters danger and needs to borrow your power, he'd better cooperate obediently. Unless he loses control himself, he's not allowed to attack Konoha ninjas."
"Please note, this is not my request. I'm just reminding you that you must make a big commotion to buy as much time as possible before I arrive to rescue you."
"With me here, Konoha has no need for the power of the Tailed Beast. If you continue to cause trouble, I won't hesitate to send you into the mouth of the Demonic Statue of the Outer Path. You'd better watch yourself!"
Nine-Tails struggled to speak, saying, "Demonic Statue of the Outer Path? How could you know such a secret...?"
Unfortunately, Shuichi ignored it. The outer body had already set up a new Eight Trigrams Seal and directly pressed it onto Naruto's stomach.
Click, click, click... The cage closed again, and Shuichi's figure was no longer visible in the mental space.
"Alright, that's basically solved!"
Shuichi smiled, put away the Scroll, healed Naruto's burns, and then carried him on his shoulder. "Let's go back."
"Phew... that was quite a commotion!" Kakashi walked over, his deadpan expression returning. "Looks like you've reinforced the seal; I don't need to worry about the rest."
"Haha, well... actually, the new seal is a little looser than before." Shuichi turned to look at Kakashi, revealing an innocent expression. "It means... when Naruto gets emotional, the Nine-Tails Chakra leaks out even faster, so you need to be careful about that."
Kakashi: "..."
What the hell?! This is a total rip-off!
"Because I had a friendly exchange with Nine-Tails, it will probably agree not to interfere with Naruto. So as long as he's conscious, your team can actually use Nine-Tails Chakra to defeat the enemy."
"However, Naruto's willpower is too weak right now. The Tailed Beast Cloak with two tails is almost the limit. As his teacher, you should try your best to cultivate his abilities in this area." Shuichi said, essentially shifting the blame onto Kakashi.
In this life, Naruto did not grow up under the villagers' disapproving gaze, and having never left the village to experience danger, his character was too naive.
He still needs to rely on the bond with Team 7 to gain love, and then go on missions to increase his experience. Anyway, the more bonded he is, the stronger he becomes.
As for whether he could eventually become the Perfect Jinchuriki, Shuichi didn't really care. He had already fulfilled his duties Hokage, and protecting the safety of the village was his top priority.
"This is way too much trouble..." Kakashi muttered helplessly, "Are you trying to kill me with exhaustion?"
"Don't worry about it, I've already arranged the training plan for those three little ones." Shuichi nonchalantly, handing over a Scroll:
"Take Sasuke for example. I deliberately slowed down his progress. I haven't taught him any Ninjutsu above B-rank. Now that you, his teacher, are personally instructing him, I guarantee he'll behave."
Kakashi curiously opened it and found everything from several B-rank Lightning Release to the Chidori style.
Haruno Sakura is similarly gifted, with various Water Release, Genjutsu, and Medical Ninjutsu waiting for her... Such treatment is absolutely unmatched by any other class.
Of course, Kakashi understands Shuichi's thoughts very well. This action shows that Team 7 all have the potential to Hokage, and it seems that getting along with them in the future will be very interesting.
Finally, Shuichi gave Kakashi three enormous Wood Release seeds to keep safe.
"When Naruto develops his Fourth Tail, throw this at him, and my power will automatically activate. Consider it an extra layer of insurance; it should be foolproof."
"I see."
Kakashi glanced at the training plan and was just about to put it away to take back for further study when he suddenly exclaimed in surprise:
"Are there really so few Ninjutsu suitable for Naruto? And you've simplified this C-rank Wind Release into a single hand seal, which actually increases its difficulty. Why did you design it this way?"
Shuichi explained, "Because in actual combat, Naruto would probably forget even the second hand seal."
Don't be surprised, he really is such an amazing ninja. His brain isn't as efficient as his body's instincts, so it's okay if it's difficult; it's better than learning it but not being able to use it.
"..."
Two weeks have passed since the Nine-Tails seal was renewed.
Naruto had sustained minor injuries, recovered and woke up in just one hour. While he was still agitated, the Medical Ninja told him the "truth": "That was a Genjutsu trap set up by hostile forces from another village, specifically targeting you. The village has already dealt with them."
"Sakura? Of course she's fine. I told you it was just Genjutsu. Don't worry, get some rest!"
Since Naruto will find out his identity sooner or later, it won't be difficult to keep him in check with this flawless explanation.
Furthermore, out of humanitarian concern, Shuichi even arranged for Sakura to visit him, making him an exceptionally kind and perfect Hokage. If the Fourth Hokage and his wife knew about this, they would surely be extremely grateful...
