"The power of the Eighth Gate: Gate of Death is truly immense. It actually boosted me this much, though it probably still doesn't compare to Guy from the original story."
Seiryū clenched his fist, feeling the surging, formidable power within his body, and could not help muttering to himself.
A stinging pain radiated from every part of his body.
Fortunately, Seiryū's pain tolerance had been "trained" up, and with Kaidō healing him, the pain in his body was greatly eased.
It was not unbearable!
"A kick that distorts space, huh. I probably can't do that right now. In terms of sheer physique, I definitely don't compare to Guy from the original story."
Seiryū pondered.
In the original story, Guy's final Night Guy distorted space, and Seiryū estimated that he could not achieve that right now.
That was normal.
No matter what technique it was, it depended on the user's performance.
In the original story, Might Duy opening the Eight Gates only reduced the Seven Ninja Swordsmen of the Mist to a joke. It was incomparable to Guy fighting Six Paths Madara head-on.
There was another reason.
Seiryū's current physique definitely could not compare to Guy's in the original story.
He was only eleven or twelve years old.
His body had not fully matured yet.
With all these factors combined, Seiryū felt that his Eighth Gate: Gate of Death could not reach the level of Guy after opening the Eighth Gate in the original story!
"After opening the Eighth Gate, did the intangibility passively disappear, and was the Dragon Vein chakra repelled?"
Seiryū also noticed it.
After opening the Eighth Gate: Gate of Death, the Dragon Vein chakra had been forced back into the Yin Seal by the chakra boosted through the Eighth Gate.
He could not stack the two states.
And Creation Rebirth, which required Dragon Vein chakra to be used, had also shut down.
"It must be because I can't control this chakra or maintain the balance between the two chakra modes. It's the same principle as Senjutsu chakra. I'm just not skilled enough."
Seiryū did not think it was impossible to stack them.
It was just that the power of forcibly opening the Eighth Gate was too strong, leading to a situation where he could not fully control it.
After opening it a few more times in the future and becoming skilled at controlling that powerful chakra, he should be able to stack the Eight Gates and the intangibility state.
"If I can fully master Dragon Vein chakra in the future and then stack the Eighth Gate: Gate of Death on top of it, forget Madara in his prime, even Six Paths level, Kekkei Mōra level, or the Ōtsutsuki Clan might get kicked into oblivion by me, right?"
A sharp glint appeared in Seiryū's eyes.
Just opening the Eight Gates was already this powerful.
If he could also stack the intangibility state while fully mastering the Dragon Vein chakra, how strong would he be?
Just thinking about it was exciting!
Six Paths level, Kekkei Mōra level, whoever it was, he would kick them all into oblivion!
"Are you crazy!?"
Just as Seiryū was thinking about this, a nervous, worried, and angry voice came over.
Tsunade rushed over, dragging her somewhat weary body, her face full of anxiety.
Gritting her teeth, she roared, "You even dare to use this kind of power? Stop it immediately!!"
What on earth had this kid done?
He actually opened the final Gate of Death!
This was the final gate, the one that meant certain death once opened!
Was this kid really not afraid of death?
Why would he not listen to her?
Nothing had happened to her, so his reaction was a bit too extreme!
"Uh, I almost forgot."
Hearing Tsunade's words, Seiryū realized it and could not help smiling sheepishly.
He had been busy daydreaming about how strong he would be in the future and had almost forgotten that he was still in the state of having opened the Gate of Death.
So, Seiryū began trying to close the Eighth Gate: Gate of Death just like he closed the other gates, and his expression stiffened the next moment.
Seeing Seiryū's stiff expression, Tsunade gritted her teeth. "What are you standing there for? Your body can't take it anymore!"
"It seems I can't close it."
Seiryū tried several times but could not close it, so he explained, "It's different from the previous gates. The chakra of the Eighth Gate is too powerful, and I can't control it enough to close it."
If he could not control the chakra, he could not close the Eighth Gate: Gate of Death.
Seiryū finally understood why opening the Eighth Gate: Gate of Death meant certain death.
This kind of power was simply uncontrollable and would continue until the user's body broke down!
And the body breaking down was almost equivalent to death.
Even Naruto, who was granted the "Yang Power" in the original story, could only maintain Guy's last breath.
"Then what should we do?"
Tsunade showed a rare look of panic, biting her red lips as she said, "Think of a way, quickly!"
If this kid died.
She would not know what to do!
She probably could not bear such a blow either!!
"Don't panic. I won't die. I had already considered this. If the chakra is uncontrollable, then use Sealing Jutsu. Our predecessors have already taught us through experience, and this isn't my first time experiencing something like this!"
Seiryū's expression was very calm.
What storms had he not weathered?
A mere fatal wound!
Was it not just uncontrollable chakra leading to the body breaking down?
Child's play!
When the Dragon Vein entered his body before, it was almost the same situation!
He just had to seal it up!
"Bakudō. Sealing Jutsu."
Seiryū began trying to seal himself, casting various Bakudō and Sealing Jutsu one after another onto his body.
He wanted to seal this uncontrollable chakra inside his body.
However.
Although it was contained.
This chakra was far stronger than the Dragon Vein chakra from back then.
Seiryū found that he could not seal it completely.
It only slowed the rate at which his body was breaking down.
"W-what happened? You."
Tsunade asked anxiously.
Before she could finish.
'Bang, bang, bang.'
Under the scouring of the violent chakra in his body, muffled explosions rang out.
The Sealing Jutsu Seiryū had applied to himself was actually forcefully broken open.
"?"
Seiryū was also stunned.
It could not be completely sealed!
Hey, hey, this was no joke.
If this continued, it would not just be a serious injury.
He might really die.
"Don't panic. I have other preparations!"
Seiryū's mind worked differently from ordinary people, and he was still quite calm at that moment.
It was as if he was not the one about to die.
Seiryū smiled at Tsunade. "If this method doesn't work, after you go back, immediately practice Impure World Reincarnation and resurrect me. I have other backup plans!"
Although he had been a bit angry just now, Seiryū had not opened the Gate of Death on a whim.
He had already been considering how not to die after opening the Gate of Death.
Seiryū had a few fairly reasonable contingency measures!
First, use Sealing Jutsu to completely seal the body and see if it could close the opened Eighth Gate: Gate of Death!
He had just tried it. This plan had failed, so skip it!
Second, at the last moment, use Kaidō to stabilize his life force, similar to the price Guy paid to avoid death thanks to Naruto's "Yang Power."
The price should be being seriously injured for a long time and waiting until he could use recovery methods to slowly recover!
This was the safest method. It just required some time to recover.
Third, dig out the heart where the Eighth Gate: Gate of Death was located and "close" the Eighth Gate: Gate of Death from the source!
The gate of the Eighth Gate: Gate of Death was right at the heart. After opening the Eighth Gate, the heart acted like the power pump of the Eight Inner Gates Formation, continuing to work until the body broke down or failed.
Once the power source was dug out, let's see how it kept working!
Then use Kaidō and Creation Rebirth to restore the heart, achieving a method similar to exploiting a bug.
This was an idea that appeared after Seiryū realized that stacking Kaidō and Creation Rebirth had an effect similar to "High-Speed Regeneration"!
Fourth, if he died, then he died!
Anyway, this world had methods of resurrection. First, let Tsunade practice Impure World Reincarnation to let his dead self "live" again in the form of an Impure World body.
Then, "apologize" to Nagato-senpai once.
Ask Nagato-senpai to do him a favor and use the Samsara of Heavenly Life Technique to resurrect him!
After that, when he was strong enough that using resurrection methods would not cost him his own life, he would resurrect Nagato-senpai.
An honest mutual life exchange!
The above were the contingency preparations Seiryū had thought of to avoid the certain death of the Eight Inner Gates Formation!
With these preparations, what was there for Seiryū to be afraid of?
As for which plan to use now?
Seiryū indicated that it was naturally the third one!
There was no other reason. The third one was the most effective!
Besides, it was just digging out a heart. What was the big deal?
"You."
Hearing this, Tsunade's expression changed drastically.
However, Seiryū did not give her time to speak and instead reminded her, "Stay farther away. Don't get splattered with blood. You used to be quite afraid of blood, and I'm afraid the scene coming up will be too bloody and cause your hemophobia to relapse."
"Come, come, come. I'll perform an open-chest act. No, it should be seppuku. No, that's not the right position."
"Yeah! Want to see my true heart? I'll take it out and show it to you right now!"
Seiryū still had the mood to talk nonsense. "I'll let you see that my 'heart' for you is so bright red and so warm!"
As a Medical Ninja, Seiryū naturally knew the Chakra Scalpel.
Plus, he could materialize and shape chakra.
Creating a chakra blade was very simple!
Speaking of which.
The Chakra Scalpel in Medical Ninjutsu was not the same as applying the properties of Yin Release chakra.
One required constant control to maintain its shape changes and would disperse if not maintained.
The other could maintain stable shape changes even after leaving his control, and it would be fine even if thrown!
Tsunade: "..."
What kind of time was this?
This kid still had the mood to talk nonsense with her here!
And what did those words of his mean?
What exactly did he want to do!?
'Shh.'
Just as Tsunade was wondering what Seiryū wanted to do, Seiryū began showing off his operation.
He picked up the condensed chakra blade and stabbed it toward his heart!
Seiryū was ruthless enough to himself.
He did not even frown when stabbing his own heart!
As the chakra blade tore through his chest, blood immediately sprayed out, splashing onto Tsunade, who had not backed away far enough.
This left Tsunade stunned on the spot.
She already could not understand Seiryū's actions.
Was this kid afraid he would not die fast enough?
"Witness the miracle, the Shinobi World's first heart transplant surgery. Uh, does this count? Forget it, whatever! The first heart transplant surgery will be born in my hands!"
Seiryū spoke in a very sacred tone, as if he were doing something great.
As a Medical Ninja, with Vollständig: Heavenly Eye that could see through the body.
Although Seiryū's knife work was ruthless, it was incredibly precise.
He cut out the entire heart with one slash.
Then, with a fierce grab, he drove his left hand into his chest.
When he took it out again, his "true heart" was beating slightly in his palm, and faint thump-thump sounds came from it.
Not to mention, it was quite powerful.
This proved that Seiryū's heart was very healthy, with no problems!
"What a miraculous feeling. The power seems to have been drained instantly. I'm a bit weak."
Seiryū's voice instantly weakened, his life like a candle in the wind that would be extinguished the next moment.
But as expected of the Uzumaki Clan, their life force was strong.
Plus, he was still maintaining Kaidō, so even with his heart cut out, Seiryū felt he could still be saved!
As for pain?
Seiryū indicated that his tolerance for pain was extraordinary.
It was all "trained"!
Instead, performing a "heart transplant surgery" on himself gave Seiryū another strange experience!
This feeling, if told to others, they would not believe it. No, there should be others who understood this feeling.
Such as Kakuzu and Hidan, that immortal duo. They should have common topics with Seiryū.
The two of them were quite twisted too.
As the heart was cut out, the blood-colored steam rising from Seiryū's body disappeared in an instant.
The feeling of weakness came because the Eight Inner Gates Formation was closed in such an unreasonable way.
"Huh? Is that Great-grandfather and Second-grandfather?"
Seiryū's consciousness began to blur, and his vision fell into darkness.
Vaguely, Seiryū seemed to see Hashirama and Tobirama ahead, turning their heads in a chaotic passage.
They looked at him with confused and stunned expressions.
"What a wonderful experience. Is this the passage to the Pure Land?"
Seiryū found this feeling very novel, but he knew he did not have much time left.
He could not let himself actually die!
He hurriedly formed seals with one hand and whispered, "Kaidō! Creation Rebirth!"
Simultaneously casting two recovery-type techniques and stacking them together gave him the ability of "High-Speed Regeneration."
As long as his head was not cut off and he had enough chakra.
Broken arms and legs were not a big problem.
The heart was not either!
In other words.
If Seiryū wanted to.
Just selling organs could make Seiryū a tycoon.
'Hum.'
At the hollow spot where his heart had been, flesh, blood vessels, and nerves began to grow from the original heart connection.
The speed was not slow, and in just a few seconds, a brand-new heart was formed.
It beat powerfully with a thump-thump sound!
"Now I finally know how important it is to have a 'true heart'! A 'true heart' for a 'true heart,' this saying is perfect!"
With his heart restored, Seiryū instantly swept away his previous weakness.
He could not be said to be full of life, but he was already out of danger!
Looking at the old heart in his hand, Seiryū handed it to Tsunade and smiled. "Here, this is my 'true heart.' Please keep it safe. Don't let me down in the future!"
Subconsciously taking the heart that had stopped beating from Seiryū, Tsunade was completely stunned.
She had a feeling that her worldview had been shattered.
What the hell!
What on earth had she just seen?
Was this a method a human could think of?
Was this something a human could do?
The Eighth Gate: Gate of Death of the Eight Inner Gates Formation, which meant certain death once opened, had just been resolved by Seiryū in this way!?
(To be continued.)
