Bang was not familiar with Saitama's name.
About two years ago, when Lynn moved from the dojo to live in Z-City, Bang had asked him the reason.
[There's a person named Saitama living in the suburbs of Z-City. He's very strong. Living near him gives a sense of security. ]
That was the first time Bang heard Saitama's name.
As a martial arts grandmaster, Bang could remain calm even when facing a Dragon-level Monster. But even he couldn't help feeling a flicker of curiosity upon hearing this reply.
After all, the dojo was his home, and Lynn had been living with him at the time.
This peculiar reply was essentially an indirect way of saying that this person named Saitama was stronger than himself.
However, Bang's temperament was gentle and tolerant. He wouldn't delve deeply into someone based on just a couple of sentences.
After getting the reason from Lynn, he allowed him to move to the Z-City suburbs. In their occasional conversations afterwards, he would sometimes hear Saitama's name, but they never met.
It wasn't until today, when he came to the Z-City suburbs to check on Lynn's mental state, that he finally encountered Saitama.
Extremely strong.
That was Bang's first impression of Saitama.
When the other party approached from behind with Lynn, neither he nor Bomb had been able to detect them immediately.
The mere fact of accomplishing that suggested Saitama's strength was not beneath his own.
And after that, Saitama's evaluation of the Flowing Water Crushing Rock Fist and Whirlwind Iron Slash Fist further ignited his curiosity.
"Since you find them average, young friend, and we have nothing else pressing, how about sparring with me for a bit?"
"Huh? Fight?"
Saitama showed a rare hint of hesitation.
He wasn't very fond of fighting with anyone other than Monsters. After all, his purpose in training to become stronger was to be a hero.
"Young friend Saitama, the Flowing Water Crushing Rock Fist is a technique I created by assimilating the ways of a hundred schools. Finding any flaws in this technique is very important to me."
Perceiving Saitama's hesitation, Bang pondered for a moment and added, "Regardless of the outcome, I will hold no ill will towards you, and I will offer a token of gratitude afterwards."
Token of gratitude?
Catching the key phrase, Saitama perked up a bit.
"Then let's begin, old man."
"Thank you for obliging, young friend. Then I won't hold back."
Receiving a definite reply, Bang hesitated no longer. He raised his hand and threw a punch directly at Saitama before him.
Facing this near-ambush attack, Saitama simply tilted his head casually and dodged it.
"Indeed, not simple."
Bang's eyes lit up, and he immediately unleashed a flurry of attacks from both sides.
His meticulously honed fist technique was now on full display. Hundreds of fist shadows instantly materialized, descending like a thousand troops and ten thousand horses.
But as if replaying the earlier scene, Saitama merely swayed left and right casually, dodging all the fist shadows.
In a daze, he stepped forward, one pace after another, towards Bang, continuously closing the distance between them.
"Huh?"
Bang finally realized the severity of the situation.
Holding back no longer, his legs suddenly exerted force. In a flicker, he appeared at Saitama's side.
But at that very same moment, Saitama's figure also vanished, reappearing right beside Bang an instant later.
"..."
Bang fell silent.
Looking at the big, bald-headed guy next to him, who appeared completely nonchalant as if nothing had happened,
he sighed inwardly and dropped his stance.
"So that's how it is. I see."
"Old man, you're not fighting anymore?"
"No more fighting. Let's end it here..."
Bomb waved his hand, a bitter smile appearing on his face.
His eighty-plus years of life weren't for nothing.
If he stubbornly continued the fight, Lynn would have to visit him in the hospital tomorrow.
"There's always someone better, indeed. No wonder Lynn says the Z-City suburbs feel safe. I'm even considering moving there."
"It's very inconvenient."
Saitama replied with complete seriousness, "The suburbs aren't well-maintained. Water and power outages are frequent."
"That's a good point too."
Bomb chuckled lightly and turned his gaze forward again.
In the brief moment he and Saitama were talking, Lynn and Bomb had already fought their way several blocks away.
Wherever the two passed through, it was as if a natural disaster had swept by. Sturdy concrete buildings were reduced to rubble, and the earth, pockmarked with craters and fissures, served as the backdrop.
After a while, the thunderous noises ceased. Lynn and Bomb reappeared on opposite sides of the street.
Compared to before the fight, the upper half of Lynn's clothes had vanished, but his body was completely unharmed.
On the other side, Bomb's martial arts uniform looked exactly the same as before the fight, but there was a streak of blood on his cheek.
"Uncle Bomb, shall we continue?"
"No need. Let's end it here."
Bomb raised his hand to wipe the blood from his face.
In truth, he had initially planned to hold back a bit.
But as the fight progressed, he realized there was no need to hold back at all. Lynn's regenerative ability was astonishingly fast.
No matter what kind of wound he inflicted, the other party could heal it in an instant and then launch a counterattack.
Unless he went all out to test Lynn's limits, continuing like this wouldn't determine a victor.
"Lynn, I understand your strength now."
Bomb pulled out a book and tossed it to Lynn: "This is the manual for the Whirlwind Iron Slash Fist. Read it through yourself today. Come find me at the Flowing Water Dojo tomorrow."
"Thank you, Uncle Bomb."
Lynn accepted the Whirlwind Iron Slash Fist manual.
Through the recent practical combat, he gained a deeper understanding of this fist technique's power.
If the Flowing Water Crushing Rock Fist is a technique leaning towards defense and counterattacks, then the Whirlwind Iron Slash Fist is a technique that pushes offense to the extreme, fitting his combat style even better.
With the sparring session concluded, Lynn waved goodbye to Bomb and Bomb and took Saitama to get dinner.
Watching the two disappear from sight, Bomb pondered for a moment before looking at his brother: "What do you think, brother?"
"No major issues."
Bomb clasped his hands behind his back.
His trip to Z-City today to fight Lynn and test his strength was only the surface-level objective.
In reality, his true purpose was to observe whether Lynn had mutated into a Monster, and if so, whether his disposition remained normal.
"Manipulating lightning and rapid recovery from injuries—these powers indeed don't seem like abilities a normal person would have. However, his aura feels somewhat different from that of a Monster."
"His martial will remains as firm as ever. Even when at a disadvantage, he stayed calm without revealing obvious openings. Overall, this transformation doesn't seem to be a bad thing."
"That's good."
Bomb finally felt relieved, his worries laid to rest.
He trusted Bomb's judgment. His brother was better at observing details than he was.
If even Bomb said so, then there was no need to worry.
...
One hour later.
After personally cooking and finishing dinner, Lynn returned to his room and took out the Whirlwind Iron Slash Fist manual.
The manual wasn't very long. Activating the State of Selflessness and entering a brainpower-enhanced state, he quickly finished reading it.
Closing his eyes, he recalled the recent fight. Bomb's every move and stance in the battle were slowed down and analyzed repeatedly in his mind.
After a while, Lynn raised his palm and casually swung it towards a spot not far away. A sharp gust of wind abruptly sliced through the air.
Accompanied by a crisp sound, the wooden chair in front of the table was cleanly split in two, the cut surface perfectly smooth.
"Not bad."
Lynn nodded in satisfaction.
Compared to ordinary fist techniques, the Whirlwind Iron Slash Fist placed higher demands on physical fitness.
If it were before, he absolutely couldn't imagine being able to unleash a wind gust rivaling sword energy with a bare-handed swing like he just did.
With the fist technique successfully learned, the next step was repeated training to integrate it into instinct.
"Time to recruit some helpers."
His consciousness slowly sank. One-Punch Lynn arrived at the Mist Plaza and called out to the other Lynns.
After a moment, a figure walked out from the edge of the plaza.
"Good morning, workaholic."
"Good evening, Jujutsu Sorcerer."
One-Punch Lynn and Jujutsu Lynn high-fived.
"Got time to help me pull an all-nighter?"
"Whirlwind Iron Slash Fist? Sure."
After receiving the memories, Jujutsu Lynn's eyes lit up.
Fist fighting was good. He loved fist fighting.
In a world like Jujutsu Kaisen where the solution to any problem is often to throw punches, being exceptionally good at punching already meant you were halfway to victory.
More importantly, mastering the Whirlwind Iron Slash Fist to its peak allowed it to be combined with the Flowing Water Crushing Rock Fist as a combo technique.
Add a Black Flash critical hit on top of that, and they might even be able to forcefully break through Gojo Satoru's defensive shell.
"How come you still haven't found a new finger on your end?"
On the other side, One-Punch Lynn, having digested the memories from Jujutsu Lynn, ruthlessly teased.
"Your efficiency is too slow. If it really doesn't work out, just go steal and eat the Sukuna's Finger stored at Jujutsu High."
"Don't rush. I've been learning barrier techniques these past few days. It's not too late to act after perfecting my Domain."
"Fine. Remember to practice the fist technique for me."
"Don't worry, I'd practice it even if you didn't say so."
After a brief chat, the other Lynns received the message and arrived in the Mist Space.
After sharing their power and finding his helper, One-Punch Lynn left the Mist Plaza and began a new round of intense self-training.
...
Jujutsu World.
His consciousness returned from the Mist Space. Lynn left his dormitory and headed towards the western training grounds.
Due to his recent battle with Jogo, the western district of Jujutsu High had suffered heavy losses, with many areas reduced to ruins.
But it was, after all, the headquarters for Jujutsu Sorcerers. Plus, with Gojo Satoru, that rich guy, footing the bill, a group of 'civil engineering saints' soon arrived at Jujutsu High.
With money as the driving force, the workers seemed powered by a nuclear engine. The overall repair speed was astonishingly fast, and many areas were already back in use.
Walking on the freshly paved concrete path, his phone rang. Lynn stopped and looked at the caller.
"Hey, Itadori, what's up?"
"Lynn, we have a mission."
Itadori's voice came from the other end of the line.
"Fushiguro is already here. He's contacting Kugisaki. We're waiting for you at the school gate."
"Alright, I'm on my way."
Lynn changed direction and ran towards the school gate.
Although the quality of Cursed Spirit in the Jujutsu World was generally mediocre, not as good as the Monsters in the DanMachi World,
Cursed Spirit that appeared still had to be dealt with. Leaving them alone would cause casualties among ordinary people.
"Where's the mission location this time?"
On the way to the school gate, Lynn asked.
"Juvenile Detention Center."
Itadori's voice came from the other end of the phone.
