"What use is a pretty face?!"
"I want power! Do you understand? Power!"
Yu detected a hint of mockery in the tone of this strange, bewitching voice.
Yu, who had been inwardly wondering if he had fallen under a genjutsu, suddenly began to feel agitated.
"In this world of ninjas, if you don't have power, you're worth less than a pile of dog shit, do you understand?!"
Ever since he transmigrated into this world, Yu, knowing the future plot, had not dared to slack off on his training for even a single moment.
After being brought back to Konoha following the battle at Jie-Geng Mountain, Yu had spent a year of hard work.
He finally succeeded in extracting physical and spiritual energy to fuse them, embarking on the path of chakra cultivation.
However, because he was still too young, although he could successfully extract chakra, his physical limitations prevented his chakra levels from reaching the level of a genin.
The Third Shinobi World War had just begun, the Six Paths of Pain would eventually single-handedly destroy all of Konoha, and the Fourth Shinobi World War would decide the ultimate existence of the world.
Faced with these events that had already occurred or were about to unfold.
Ever since arriving in this world, Yu's heart had been suppressed for far, far too long.
"Of course I understand."
"But this is not a genjutsu, so you don't need to waste your effort searching for one."
Feeling the near-runaway state of Yu's emotions, the bewitching voice began to sound increasingly languid. "I am hidden deep within your soul; it was your craving for power that awakened me."
"Deep within my soul?"
"No wonder your voice didn't seem to come from the outside; I thought I had been caught in a genjutsu just now."
Listening silently to this voice from the depths of his own soul, Yu narrowed his amber eyes, his mind beginning to race. "Then what exactly are you? And what can you give me?"
"I am a devil."
Sensing the intense craving for power within Yu's heart, the voice, as intoxicating as poppy, paused slightly, as if to drag him into an abyss of eternal damnation. "As long as you hand your soul over to me, I can give you the power to dominate everything!"
"A devil, huh..."
"Tch, how cliché."
After subconsciously retorting, Yu secretly clenched his small, tender fists, his eyes flickering with a deep, profound desire for power. "You want my soul, right?"
"Take it! As long as you give me enough power to rule this world! Take it all if you want!!"
Ever since arriving in this ninja world woven with iron and blood, Yu's desire to become stronger had been as intense as a drowning man's need for air.
"Very good!"
Seeing Yu agree to the deal without hesitation, the devil deep within his soul nodded in satisfaction. "Then I shall bestow upon you the Devil Law!"
Devil Law??
What the hell is that??
Listening to the devil in the depths of his soul, just as Yu felt bewildered, he suddenly felt a completely foreign power surge into his body.
This strange power was entirely different from the chakra he was currently cultivating.
Yu felt as if his entire body had been reforged, and it began to undergo earth-shaking changes.
"What is this?!"
"My body feels different than it did a moment ago!"
Looking at his hands and body with surprise and astonishment, Yu felt that he had changed, though he couldn't quite put his finger on how.
"Aha, it seems your luck is quite good; you actually drew the law of the String-String Fruit."
At this moment, the devil inside Yu began to sound quite gleeful.
String-String Fruit?!
Yu froze, a bolt of lightning flashing through his mind.
Holding a sliver of curiosity, he suddenly swung his small, tender hand forward with all his might.
"Bang!!"
A shocking scene unfolded!
From Yu's fingers, a transparent, invisible, and nearly imperceptible thin thread was whipped out.
Carrying the full force of Yu's strike, a loud bang echoed as the wooden target in front of him was sliced clean in two!
The cross-section was neat and smooth, as if it had been severed by an invisible, razor-sharp blade.
"What is this?!"
Seeing the effect produced by his own palm strike, Yu stood there completely stunned, but he quickly realized, "This... isn't this the String-String Fruit from One Piece?!"
His mind immediately conjured the image of the Paramecia-type String-String Fruit ability belonging to Donquixote Doflamingo, the 'Heavenly Yaksha' and one of the Seven Warlords of the Sea from One Piece.
How could Yu not understand what was happening? His amber eyes widened in shock. "What Devil Law? Isn't this just the power of a Devil Fruit??"
"In essence, there is no difference between the two."
"Although I am a devil, I currently lack a physical body and cannot directly produce a Devil Fruit for you."
Facing the ecstatic Yu, the devil deep within his soul seemed to smile. "So, I have bestowed the power of the Devil Fruit upon you directly in the form of a Law."
"You should know, this is a power even purer than a Devil Fruit."
"At the very least, you won't have to fear seawater because you've been forsaken by the ocean."
A Devil Fruit that doesn't require fearing seawater?!
Listening to the words of the devil in the depths of his soul, Yu's young face froze in surprise.
If that was the case, wouldn't this so-called Devil Law be even stronger than a Devil Fruit??
"Hmm... that actually sounds pretty good."
Coming back to his senses, Yu rubbed his smooth chin and nodded in satisfaction. "This way, I won't have to taste the Devil Fruit, which is rumored to taste worse than shit..."
"That is not all."
Sensing the irrepressible excitement in Yu's heart, the devil in the depths of his soul continued to elaborate: "Furthermore, as your chakra level increases, I will grant you a brand-new Devil Law."
"What??"
Suddenly hearing what the devil inside him said, Yu's handsome little face lit up with excitement. "There's actually such a good deal?!"
"But don't get too happy too soon."
As expected, there was no such thing as a free lunch; the devil deep within Yu's soul immediately poured cold water on him. "Just like Devil Fruits, a person's body cannot contain two Devil Laws at the same time."
"If that's the case, then what use is it for you to give me more Devil Laws?" Hearing this, the smile on Yu's face instantly froze.
"That is why, at this point, we need to use some mediums." The devil deep within Yu's soul began to guide him. "For example... there is a profession in this ninja world called a puppeteer."
"A puppeteer?"
Hearing the devil's words, Yu frowned slightly, asking in confusion, "Why? Can't you just grant the Devil Law directly to a target I choose??"
