The passionate BGM in Naruto's mind came to a screeching halt. Hidan's appearance hadn't morphed into some Lovecraftian horror, but that only made Naruto even more panicked.
Because within Hidan's distorted voice, he heard Boruto's voice.
Right now, Hidan's grin stretched ear to ear, his head tilted at an unnatural angle as he babbled nonsense about not being able to tell things apart.
Sasuke noticed that Naruto didn't move and frowned.
'What the hell is that noise?'
'Why does that guy's voice sound a bit like Boruto's?'
Sasuke turned his head and looked back, then at Naruto's pale face.
"What's wrong?"
Naruto's hand trembled as he pointed at Hidan, his lips trembling violently.
"BORUTO!!"
"DID YOU STEAL MY BOOKS!?"
His blood pressure has soared to Hiruzen's level.
Although he didn't know how this kid got into Hidan's body, Naruto planned to deal with this cheap son, who stole his forbidden book, first.
'Damn it!'
'This world already has an Uchiha Xiao Yan.'
'What? You brat actually want to be a Uzumaki Huowang?!' (T/N: The book Boruto stole is Dao of the Bizarre Immortal, and the MC's name is Li Huowang.)
"Naruto?"
When Sasuke saw his good brother take out his weapon, he also took off the Xuan Heavy Ruler on his back.
"You go save Mitsuki first."
"I'll take care of this damn brat!"
Today was supposed to be about taking down the villain Hiruko and saving the world.
Who would've thought it'd turn into a father-son beatdown instead?
Sasuke hesitated for two seconds after hearing this, and finally nodded, transforming into lightning and disappearing.
"Boruto! I'm going to spank your ass that they will crack today!!"
Naruto carried the Black Coffin without any fear.
In response to Naruto's words, Hidan, who was in a strange state, held his head with both hands and shook it from side to side, while stomping in place.
"No! You're not my father!"
"My father is the Nanadaime Hokage!"
"Fake! It's all fake!"
"Everything is fake!"
"Don't come here... I-I'm not scared of you!!"
Hidan held his head and roared, Naruto was now certain this brat had somehow used this cultist as a medium to manifest in this world.
As Hidan's distorted voice echoed, a crimson storm erupted around him, and Naruto was faced with disgusting smell of blood.
Hiss…
At this moment, a long tongue suddenly lashed toward Naruto's face, making him annoyed on the spot.
"Damn it!"
"You dare fight back!?"
"You think just because you're possessing someone, you're amazing now!?"
Naruto frowned, revealed a savage look, and he activated the Mount Myoboku's Sage Mode on the spot. Orange eye shadow climbed into his eyes, and the Chakra in his body instantly surged.
Grasping Black Coffin's hand, a large amount of Chakra immediately poured into it.
The Golden Rinnegan opens, and the Time Acceleration was activated!
'Let's go, Kurama!'
Under the three-second time acceleration, Naruto clearly felt the tongue wrap around his waist and yank him forward.
The moment time resumed, leaned back and disappeared from the spot.
"Dad!"
"I missed you... I really missed you!"
"No one believes what I said..."
"I'm not crazy... I'm really not crazy!"
Boruto's voice, which is now speaking through Hidan, shifted between grief and fury.
But now, Naruto just wants to teach this book-thieving brat a lesson.
"Crazy my as*!"
"SHUT THE HELL UP!!"
Whoosh…
Naruto clasped the Black Coffin with both hands, stepped horizontally, twisted his waist, and with the help of strong inertia, he swung at Hidan's face with full force.
In his eyes, Boruto just deserves a beating.
'You read that book and now you're putting on a whole act?!'
'You really didn't learn well at the young age.'
Naruto had seen this kind of thing before.
In his previous life, a teenage boy from a relative's house read two novels and suddenly started whining about being 'depressed'.
'Just needed a good beating!'
Bang…
With the heavy blow, Boruto, who possessed Hidan, fell back uncontrollably and lay straight on the ground.
Naruto seized the opportunity, walked up to him in three steps, raised the Black Coffin high and smashed it at him again.
"That's it?"
"You still acting tough!?"
"Steal my books again!?"
"Keep shouting?"
Boom…
Boom…
Naruto cursed as his hand kept hammering down relentlessly.
Each strike sent the blood-soaked dirt flying, mixed with Hidan/Boruto's agonized screams.
Last time he met Boruto, he hadn't gone all out because he was just worried he might actually kill him.
But it's different now!
Boruto was possessing Hidan, which has immortal body.
He could go as hard as he wanted, and there will be no consequences.
Rustle…
At this time, Naruto, who was beating his son, noticed from the corner of his eye Hiruko's figure flying upside down from the cave.
Sasuke carried the Heavy Xuan Ruler on his back, cracked his neck and strode toward Hiruko with unhurried confidence.
"Heh."
"You think you're strong?"
Hiruko wiped the blood from his mouth and slowly got up from the ground. When he looked at the young man in black cloak, his face was filled with contempt.
"Just ordinary Lightning Release..."
"Let me show you what real speed is. "
After Hiruko finished speaking, he activated his Storm Release and instantly appeared before Sasuke.
"Goodbye, kid."
Grasping a bolt of lightning in his left hand, he slashed it toward the black-cloaked young man's neck.
Hiruko's reflexes were indeed faster than Sasuke's, so fast that Sasuke could only manage to lift his head in response.
But...
That was enough.
The moment the lightning touched Sasuke's neck, Hiruko's pupils abruptly contracted.
Because he saw the legendary Mangekyo Sharingan!!!
Zzztttt…
Sasuke activated his left eye, instantly dragging his opponent into the special space.
"Heh, you bandaged white-haired old geezer!"
"Remember this..."
"This technique is called Yasakatome!"
When Hiruko heard Sasuke's words again, he suddenly found himself in a forest.
There is also a three-story villa at the center of the forest...
Meanwhile, in the outside world, Naruto, who was still committing child abuse, noticed that Sasuke and Hiruko had disappeared at the same time, and frowned slightly.
'Strange...'
'How did they disappear all of a sudden?!'
'Was Sasuke about to get wrecked in some unexpected way?'
"Don't worry about him."
Just as Naruto was puzzled, the Immortal Emperor Kurama spoke up.
"That familiar power..."
"Is that the Mangekyo?"
The big fox's muttering instantly made Naruto put a little more force into swinging the Black Coffin.
'Damn it?!'
'When the hell did Sasuke awaken his Mangekyo!?'
'And he didn't even tell me?!'
'Was this bastard saving this move to use against me?!'
Naruto became a little angry when he thought of this.
'Good, good...'
'Forget it about secretly dressing up as a woman, but you can't even tell me about awakening the Mangekyo?'
Naruto glanced at Hidan, who was barely breathing on the ground, and added even more strength to his strikes.
"Ahh!"
"Dad, stop hitting me!!"
"I'm sorry, I'm sorry!"
Boruto, who was beaten continuously, lay on the ground, weeping pitifully with Hidan's body.
His previous deranged demeanor was gone, and even his eyes became clear.
Hearing the guy's pleas for mercy, Naruto stopped his assault, further convinced that this kid just needed a good beating.
The only thing that felt awkward was seeing Boruto crying like this while using Hidan's body.
It was kind of gross.
"Na... Naruto..."
"Something's wrong."
"I've never sensed Chakra like this kid's before..."
In Kurama's vision, behind Hidan stood the faint silhouette of a thirteen or fourteen-year-old yellow-haired boy, who was clearly an older version of Naruto's son.
But what confused the fox was...
He suspected that there was something wrong with Boruto's mind, as he actually wore a mask made of coins on his face.
Moreover, the kid's body was emitting faint traces of black-red Chakra...
