The Power of Shockwaves.
This was the third method, the final method, and also the one Yuya was most confident about!
Buzz!!
Even though he had adjusted the intensity of the shockwaves to the lowest level, the moment he unleashed that power within his heart, Yuya's vision instantly went dark.
He almost passed out.
But...he succeeded!
The door in Yuya's heart, which should have been the "Death Gate," the eighth of the Eight Gates, was forcibly blasted open with a tiny crack under the force of the shockwaves!
Coming back from the brink of unconsciousness, feeling the completely different flow of power in his heart, Yuya couldn't help but reveal a trace of excitement and joy on his face.
The power of shockwaves—it really could serve as the key to unlocking the first gate in his heart!
That meant, aside from himself, perhaps there was no one else in this world who could train in this reverse Eight Gates technique!
At this moment, the first gate in his heart had only been ripped open by a sliver.
But the power surging from his heart was already countless times stronger than before.
And as the power of his heart grew, the flow of blood would bring even greater strength, further enhancing Yuya's body step by step, forming a perfect, positive cycle.
That alone was enough to surprise Yuya.
But the benefits didn't stop there!
At the moment when that gate in his heart was blasted open, Yuya also felt a strong surge of chakra brewing there.
Chakra flowing within his heart!
As that chakra brewed, it simultaneously nourished his heart.
And with the heart being nourished and strengthened by chakra, it beat with even more power, blood surging through his veins!
This was the second positive, mutually amplifying cycle!
Even Yuya hadn't expected this.
"I didn't think that forcefully opening the gate would allow me, with a body that struggled to cultivate chakra, to directly gain powerful chakra!"
A look of uncontainable joy flashed across his face.
He immediately recalled that when the Eight Gates are normally opened, it's essentially breaking the shackles of chakra within the body—but that chakra is temporary, just a burst of power.
But what Yuya now possessed...was permanent!
Yuya could feel that the chakra in his heart was already at the level of a Genin.
With that amount of chakra...
Even in terms of ninjutsu, Yuya would completely break free from his previous destiny as a failure!
It wasn't that he couldn't learn ninjutsu; it was just that his chakra reserves were so low that it was difficult to refine and hard to gather, which made training impossible.
But now, with the first gate in his heart barely halfway open, his chakra had already been tremendously amplified, and he didn't even have to actively refine it. What a perfect kind of power!
That chakra would be stored in his heart, continuously amplifying and strengthening with his heart's power, nourishing each other in return.
And Yuya instantly understood that perhaps, as he unlocked the second gate and even the third, his chakra would continue to grow stronger.
The path he would walk in the future was already laid out clearly in front of him!
But for now, Yuya needed to fully open the first gate.
"Next, I'm going all out!"
Yuya's face lit up with excitement as he continued to use the shockwave force to strike, simultaneously mobilizing the chakra within his heart. The two forces combined.
Boom! Boom! Boom!
The gate in his heart, which had already been cracked, now under the force of the combined shockwaves and chakra, shattered open as if it was nothing!
Buzz!!!
At that moment, it was as if a powerful aura surged from Yuya's body, causing Might Duy, who had been guarding him, to look over with utter shock.
The barrier in Yuya's heart had been completely removed, as if there was powerful chakra brewing there, seemingly about to activate the Eight Gates Formation!
But in the end, that power was exactly as Yuya imagined—not fully erupting, but instead spreading into the other unopened seven gates.
Only when all seven other gates were opened, and then the heart's "Death Gate," could the terrifying power of the Eight Gates Formation be unleashed.
Opening it as the first gate wasn't an explosion—it was stability!
At this point, the first gate of the reverse Eight Gates was completely opened by Yuya!
His chakra reserve, which was once almost impossible to extract even a trace from, had surged to rival that of a Genin!
At the same time, his physical strength, power, and speed had all been significantly enhanced.
It was practically a full-scale upgrade.
If before, Yuya would have struggled against a Genin, now\...a Genin was no longer his opponent!
However, due to the sudden surge in power, Yuya did feel a bit of discomfort.
Pfft!
Blood surged up his chest, and Yuya spat out a mouthful of blood, though there was no worry on his face.
Having just gained a Genin-level chakra reserve, it was only natural he would struggle to control it.
With the heart's restriction lifted, the heart that could now burst forth with even greater strength hadn't yet been reinforced to handle it.
But as long as the chakra and heart continued to nourish each other, he would soon adapt perfectly.
"Yuya, are you alright?!"
Seeing the powerful surge of energy just now, then suddenly calm down, followed by Yuya spitting blood, Might Duy rushed forward in shock and concern.
Yuya shook his head, took a deep breath, and gradually calmed the rampaging energy inside his body.
"I'm fine, but it seems like I still need some time to stabilize things."
"It's okay, Yuya...you're already a genius. To even come up with a training method like this, even if it didn't work out, I'd still admire you."
As he spoke, Might Duy patted Yuya on the shoulder comfortingly. "Victory and defeat are just part of the process. Even if it doesn't work, training in the standard Eight Gates with me will be enough to master Taijutsu…"
Yuya, who had just calmed down the rampaging energy in his heart, listened to Might Duy's comforting words, and his expression became somewhat strange.
"Uh, I don't think I said I failed."
"Right, even if you fail, it's still—wait, what?!"
Might Duy was still rambling on when he suddenly realized what Yuya just said. He instantly widened his eyes and stared at Yuya.
His face was full of disbelief.
"You...you succeeded?!"
"Yeah."
Yuya shrugged.
Boom!!
It was as if a thunderclap exploded in Might Duy's mind, his brain roaring with the shock.
He stared at Yuya as if he were looking at a monster, his expression utterly incredulous, his mouth agape and unable to close.
Are you kidding me?!
That reverse Eight Gates...it actually worked?
Did Yuya just turn the history of the Ninja World into dust?
This guy is a freaking monster!
