In the end, despite the nagging feeling that it was impossible, Yuya clenched his teeth and swallowed the strange fruit that seemed to be a devil fruit without hesitation.
One second... two seconds...
Nothing. Was it a failure? Or simply dormant?
"Seems it's not a poisonous strange fruit, but it also doesn't seem to have any special abilities," he muttered, disappointment creeping into his voice.
Yuya stood there, his eyes narrowing slightly as he tried to recall the nature of the fruit's abilities. It had been a long time since he arrived in this world, and his memories were starting to blur.
But even now, he hadn't sensed any abilities manifesting. It seemed it was just a whim; that fruit just happened to grow that way.
"Forget it," he sighed, shaking his head.
With determination coursing through him, Yuya returned to the wooden post where he had been training, lit a lamp, and prepared to start his practice of five hundred straight punches.
However, just as he tightened his fist, ready to strike the wooden post, astonishment washed over him.
"What is this?!"
In that instant, he felt the chakra within him begin to flow, a warm surge spreading through his veins. A delicate white halo shimmered around his fist, catching the light in a mesmerizing dance. Yuya's breath caught, and his heart raced as realization struck him like a bolt of lightning.
Could this... be the ability of that devil fruit from earlier?
"Wait, this white halo feels so familiar, could it be..."
Disbelief flickered in Yuya's eyes, as if he had been struck by a grand prize falling from the sky. This halo, though barely visible, was unmistakably linked to that ability!
With adrenaline surging, Yuya punched the wooden post with all his might.
Buzz!!!
As his fist neared the wooden post, the white halo erupted in a brilliant explosion.
Crack!
A soft yet distinct sound echoed from where his fist made contact, reminiscent of ice or glass shattering, as fine cracks spread into the air. The shockwave shattered the air like glass breaking under pressure, splintering the stillness of the grove.
Then, a powerful shockwave surged forth, crashing into the wooden post, which had already been deeply dented by Yuya's earlier strike.
Crack!!
The wooden post was forcefully broken from that dent!
Retracting his fist, Yuya could no longer hide his elation.
This was it! This was the ability, the one known as one of the strongest fruits in the world of One Piece... the Shock-Shock Fruit!
The person who eats the Shock-Shock Fruit can unleash all kinds of shockwaves—air shocks, earthquakes, or sea quakes. When developed to the extreme, it even possesses the power to destroy the world.
At this moment, Yuya didn't even think about why a devil fruit would appear in the Naruto world; he was overwhelmed with excitement, clenching his fist and gazing at the faint white light, his heart racing with exhilaration.
With this, even if he couldn't practice ninjutsu, what did it matter?!
After a long, tense moment, calm finally settled over Yuya.
"Although it's incredible to have gained the power of the Shock-Shock Fruit, it seems to be slightly different from what I imagined…"
Pondering this, he approached a large tree.
The previous wooden post had already been broken, so he could only use this tree to test it out.
"Ha!"
With a determined shout, Yuya tightened his fist.
Buzz!!
The white light appeared again, though it was dimmer this time.
In the next moment, Yuya swung his fist towards the tree trunk.
Boom!
A thunderous sound erupted, but Yuya's fist did not touch the tree trunk; it stopped just inches away, yet he still felt as if he had struck something solid. The impact reverberated through his arm, sending a jolt of energy coursing through his body.
This was the power of the Shock-Shock Fruit's air shock, capable of hitting the air as if it were a solid object. With further development, it could even shatter space!
Crack!!
Fine cracks spread through the air around him, making it seem as if space itself was fracturing.
However, these cracks were very thin.
The tree, thick as a hug, shook slightly from the impact of the shockwave, causing a few leaves to flutter down.
"Tsk... it's indeed impossible to shatter everything with just one punch right after obtaining it; I still need to train hard and keep developing it."
Yuya's brow furrowed as he contemplated his next steps. The thrill of discovery mingled with a sense of urgency. He needed to push his limits.
Because just now, when he used the ability of the Shock-Shock Fruit, he felt a slight consumption of chakra within him.
Of course, it was just an extremely minute amount.
Could it be that the power of the Shock-Shock Fruit in the Naruto world is completely linked to chakra, turning it into something similar to the Shock Release Bloodline Limit?
With this doubt, Yuya continued his detailed testing.
After a while, he finally began to understand the power he had obtained.
The Shock-Shock Fruit was now referred to by Yuya as the Shock Release Bloodline Limit.
It allowed his punches, physical techniques, and even thrown shurikens and kunai to carry shockwave power.
However, the magnitude of this power was directly linked to his physical strength.
Simply put, the stronger the body... the greater the shockwave power he could unleash!
If Yuya could now open the eighth gate of the Eight Gates of Death and enter the state of the Eight Gates, it wouldn't be impossible to shatter the moon with a single punch!
Moreover, the shockwave power also consumed chakra, but it was minimal.
The chakra consumed to unleash the shockwave power was even far less than that of a D-rank ninjutsu, and even with Yuya's poor physique, he felt no pressure in activating it.
This meant that chakra consumption was not a concern; what was most important for Yuya was to enhance his physical strength and train in physical techniques!
The stronger his physical techniques, the stronger the shockwave power he could exert.
Right now, Yuya's fist could only slightly shake the thick tree, causing a few leaves to fall. It would be very difficult to shatter a C-rank ninjutsu, and this level was clearly not satisfactory for Yuya.
He needed to become stronger!
"There are still quite a few forbidden techniques to enhance the body, Sage Mode... super strength... the Lightning Release techniques of the Third Raikage from the Cloud Village... and the Eight Gates of Death…"
With each thought, a glimmer of hope appeared in Yuya's eyes, but in the end, he could only smile wryly.
Because he currently had none of these, and they were hard to obtain.
Thinking of this, Yuya stopped his wild thoughts and decided to focus on steadily increasing his physical strength. Once he became strong enough, he would slowly seek out these techniques.
Just as he was about to continue his training, a flash of inspiration struck Yuya's mind.
