I'm doing Jujutsu Kaisen in the ninja world.

Obscene!

"Wait a moment!"

Shinji suddenly interrupted Kakashi's pretentious spellcasting with a thunderous roar.

Kakashi's heart skipped a beat when his spell was interrupted.

This guy jumping out now is definitely up to no good.

Clearly, he guessed correctly, but there was no reward.

"We finally managed to meet, how can it end so abruptly?"

Kakashi said in a deep voice, "So you mean...?"

"Since we've met today, why don't we give Sasuke another lesson and show him what a real battle between strong people looks like?"

Upon hearing this, Kakashi immediately understood Shinji's sinister intentions. Shinji wanted to take this opportunity to teach him a lesson and get revenge for his past targeting.

"Maybe next time, I used up a lot of energy just now."

At this point, Kakashi didn't try to hold on any longer and readily admitted that he was exhausted.

Sasuke didn't suspect anything when he heard that.

After all, given the terrifying power just now, it's normal for it to have consumed a lot of energy.

The ball was kicked back to Shinji.

Shinji didn't expect Kakashi to be so decisive, but it didn't matter. He had anticipated that the guy wouldn't agree so easily.

"It's alright. Since you've expended a lot of energy, let's skip the ninjutsu and just exchange techniques."

"The activity we just did wasn't even a warm-up."

Oh no, I've been infected!

Seeing the smile on Shinji's lips, Kakashi immediately realized something was wrong; he had been careless.

[Chapter 451: A Chaotic Fist]

Forget ninjutsu, just pure taijutsu?!

Kakashi's heart skipped a beat. He thought to himself, "This bastard still won't let me go. He's going to make me lose face in front of Sasuke!"

Although he believed his physical skills were not bad, he also had to consider the situation and who he was comparing himself to.

In comparison, he was more confident in his ninjutsu.

However, with the tiny bit of chakra he has left, he probably can't unleash any powerful ninjutsu.

Most importantly, what excuse should I use if I have to refuse again?

Wouldn't the image of a wise teacher that we just painstakingly built up be about to collapse?

However, Shinji didn't give Kakashi a chance to refuse, shouting, "I'm here!"

And then it really happened!

A particularly simple and unadorned punch, with neither speed nor power being particularly remarkable.

This made Kakashi hesitate instinctively, not saying what was on the tip of his tongue, but instead instinctively blocking and counterattacking!

boom!

Shinji was knocked back more than ten meters by Kakashi's punch, and each time he stepped on the ground, he created a deep crater, as if he couldn't withstand Kakashi's enormous strength.

"Alright, as expected of Kakashi Hatake! He's really amazing! In that case, I'll show you my true skills."

Hearing Shinji's loud shout, Kakashi looked at his fist in confusion.

When did I become so amazing?

That punch just now was incredibly powerful?

He was completely bewildered, and then Shinji knocked him senseless.

Shinji charged forward again, throwing the same punch, but this time the speed and power were far superior to Gang's.

Kakashi's face instantly changed color. He barely managed to block with his left arm, and the pain made him grit his teeth, feeling as if his bones were about to crack.

"That power and speed...this guy was deliberately holding back!"

Kakashi wasn't stupid either; he immediately realized Shinji's sinister intentions and blocked his escape route.

After all, given the power of his previous punch, there was no reason for him to call for a halt.

With no way out, Kakashi could only grit his teeth and begin to fight back.

He wasn't worried about his life or safety; at most, he'd just get beaten up.

Because he had already figured out the other party's purpose.

Thump thump thump...

Under a barrage of powerful punches, Kakashi's defenses could not withstand prolonged attacks, and finally, a gap was blasted open in his defensive line.

Then Shinji punched Kakashi in the stomach.

The sharp pain in his abdomen caused Kakashi's forehead to instantly bead with cold sweat, but he endured it and, in a moment of momentum, delivered a punch to Shinji's face.

Shinji let out a scream and flew backwards for 7 or 8 meters, which was extremely exaggerated.

There wasn't even any redness or swelling...

Kakashi was so angry he almost ground his teeth to powder.

He was clearly the one in so much pain he was about to vomit blood, yet he seemed to be the one who had the upper hand.

What's even more infuriating is that after that bastard got up from the ground, he kept putting on an act.

"Such power, such speed! It seems I made the right choice in my opponent. Sasuke, watch closely, this is what a battle between men should be like!"

Kakashi was being pushed higher and higher by Shinji, and it was too late to say anything now.

I might as well go all in and fight it out.

Even if it means getting beaten up, I'll make that bastard pay!

"Good timing!"

Shinji shouted, his eyes shining with excitement, and then he didn't fight back at all, letting Kakashi's storm of attacks rain down on him.

Of course, he wasn't the only one taking the beating.

He always throws a punch secretly when Sasuke can't see him, catching Kakashi off guard.

They specifically target areas like the kidneys, ribs, and lower abdomen for striking.

Then you can see that even though Kakashi is clearly dominating Shinji, his expression is becoming more and more ferocious, and his eyes are getting wider and wider.

Kakashi had contracted a group of ninja dogs, but he had never seen anyone as dog-like as him before.

Leaf Whirlwind!

Seizing the opportunity, while Kakashi was using Leaf Whirlwind, Shinji simultaneously delivered a spinning kick, striking Kakashi in the face and sending him flying.

"what!!"

Shinji let out a cry of pain, and using the force of kicking Kakashi, he flew in the opposite direction and crashed heavily to the ground.

In reality, Kakashi's kick didn't even hit him.

"Kakashi Hatake, your strength is indeed formidable! Even your taijutsu is on par with mine, but the battle has only just begun, and we must determine a victor today!"

Shinji, who had stood up again, covered his perfectly healthy left cheek and spoke loudly and righteously.

Kakashi, whose teeth had been loosened by the kick, quietly pulled down half of his mask, spat out a mouthful of bloody saliva, and looked utterly helpless.

They're not even giving him a chance to surrender.

So the two of them got back up and started 'fighting' again.

Bang, bang...

Kakashi, feeling like his kidneys were about to explode, endured the pain and found an opportunity to ask in a low voice, "What exactly do you want? Even if you don't like me and want revenge, shouldn't you have done enough?"

"Hehe, is it that obvious?"

"...What do you think!"

"I had no choice. I finally got this chance. If I don't give you a good beating this time, I won't have another chance."

"..."

Shinji's honesty left Kakashi speechless, and he thought to himself that he was really unlucky to have run into such a vengeful guy.

So what if I monitored you for a while, misunderstood you a few times, and even got into a fight? Is it really necessary to hold a grudge like this?

Hmm... thinking about it now, he really does seem to be quite hated.

"Tell me, when will this be over?"

"Hurry up, just like before, let me beat you up, and we'll call it even."

"Fine, I admit defeat. Go easy on me, don't hit my face..."

"Ah, I know, enough with the nonsense."

Ada!

Just as he finished muttering to himself, Shinji punched Kakashi in the face, giving the guy a black eye.

Kakashi was speechless, then gritted his teeth and fought back.

Their original routines and tactics gradually disappeared, and the fight devolved into a brawl between street thugs.

The reason was that Kakashi's stamina was almost depleted, and coupled with the constant beatings, he simply abandoned all technique and almost started throwing wild punches.

Shinji had no idea that Kakashi had this kind of fighting style. In order to appear evenly matched, he was forced to resort to random punches.

This really put Sasuke, who was 'watching and learning' from the sidelines, completely dumbfounded.

"Is this what a battle between masters looks like?"

"Does Brother Shinji mean to me that the ultimate goal of physical training is to return to simplicity?"
