15 One Punch!

"The underground is quite spacious."

The underground space must be as vast and extensive as a subway station. After descending a flight of stairs, they found themselves on a straight road paved with steel and concrete, wide enough for a large truck to enter and exit. Each step echoed back a long reverberation upon hitting the ground.

Although it was unclear if he meant it sincerely, Saitama, with a softened expression, remarked, "It's quite exciting."

Saitama's tone was overly plain, to the point of being blunt.

Meanwhile, Roy pondered about something else, "The resources, technology, and manpower required to build this underground base are not something ordinary individuals can bear. Hmm, although Dr. Genus has developed an organization similar to religion, to be able to construct such a structure, it seems Dr. Genus is quite powerful."

Considering the marvelous technological level of this world, such a degree was acceptable.

In daily life, the technological achievements enjoyed by this world were not much higher than those of the 21st century. This was also why Roy didn't need to spend much time adapting to life in this society.

However, on the other hand, scientists hidden in this society often possessed technologies surpassing those of a generation or more.

Tactical armed robots, mechanically modified life forms, artificial monsters, autonomous construction robots, and even medical technology capable of saving those on the brink of death... It wasn't an exaggeration to say that if these technologies were published or cooperated with the government, within less than 20 years, we could colonize the moon. And given 50 to 100 years, we might even venture out into the solar system.

But the people who possessed these technologies didn't have such ambitions. More often, they acted based on their own desires.

Of course, Roy had no position or qualification to say whether anyone was right. Strictly speaking, Roy was one of them. Regardless of what Roy learned from Yumemi Okazaki, just Roy's supernatural ability... Dark Matter was enough to profoundly change the world.

One of the reasons why many scientific and technological designs and hypotheses couldn't be realized was because of material limitations.

If one could obtain any material they wanted, even many black technologies could be realized. If everything was interconnected, breakthroughs in one aspect of nature could bring about significant developments in another. Solving the material problem could actually incidentally solve the energy problem as well. After brain-teasing technologies were realized, countless stars in the universe could serve as energy sources.

So, if Dark Matter were truly contributed, regardless of how many years it would take, developing to the level of a Kardashev Type III civilization shouldn't be a problem, right?

In any case, even with these achievements, Roy didn't feel the need to engage in such activities.

Lack of strong desires and concepts in this regard was one reason, and feeling it was too troublesome and tiring was another. However, if someone with insight came to lick his boots for help, there was a good chance Roy would agree. Simply put, he wasn't proactive.

"The life reactions are deep inside this building, but many of the reactions are of the same kind. Are they clones?" Genos diligently performed his task, and he seemed to have sensed something as he looked up. "Sensei, Roy-san, there are two life reactions approaching us. Please be careful!"

Since it was a straight road, there were basically no obstacles blocking their line of sight.

They saw a humanoid creature of about three meters tall, clutching a man's head, rapidly approaching.

In fact, before entering their line of sight, the echoes of something approaching could already be heard on the road.

"Oh, found them. There are three. Which one?"

"The one without hair..."

"Then the other two are unnecessary!" The horned humanoid creature grinned wickedly. "Let's kill them all!"

'Is it that anyone with a bit of strength in this world becomes arrogant?'

Just as the horned humanoid creature that goes by the name Carnage Kabuto was about to punched Genos into what resembled a piece of modern art, Roy's drooping eyelids snapped open.

Swish...

"Eh?"

Carnage Kabuto froze.

Dr. Genus, who was caught in Carnage Kabuto's hand, also froze.

Although it seemed like a punch had been thrown, the seemingly unremarkable youth stood unharmed in the same spot. But the once clean and tidy corridor was now stained red with copious amounts of blood.

"Waaaahhhh... My left hand!!!!"

Indeed.

Carnage Kabuto's left hand had been severed.

At an unbelievable speed.

There was a black mist-like substance swirling around Roy's right hand, mixed with flashes of white.

"H-How is this possible!" Driven by the shock of losing one hand to Roy, Dr. Genus, who had been thrown to the side, struggled to stand up, his face filled with disbelief as he stared at Roy, who remained expressionless.

'Carnage Kabuto... He's the strongest mutant I've ever created. Since his birth, he has never been defeated. Even the so-called heroes were only equals at best! Although he's a flawed product in terms of character, his performance is overwhelming! How could he lose a hand without even reacting...'

Dr. Genus felt incredulous.

"Shit..."

Carnage Kabuto's panic didn't last long. It would be more accurate to say that extreme anger quieted it down. Its muscles began to swell all over, from about three meters to over five meters, and its entire body transformed into a paint scheme.

"You've thoroughly angered me! I'm going to torture you all to death now!" Carnage Kabuto, in Carnage Mode, looked like it was about to go completely berserk. "Hooahhhhh... After activating this mode, I'll lose my sanity for a whole week, and my fighting instincts won't be quelled!"

The hand that had been severed by Roy's attack on Carnage Kabuto's original body wriggled for a moment at the wound, then flew back to Carnage Kabuto's body. The damage caused was completely restored in an instant.

"Next, I'll completely massacre you. Then I'll go to the town and continue killing until next Saturday!!"

Ah, this guy said what shouldn't be said.

"N-Next Saturday, and then it continues for a week, which means..." Saitama's expression was so shocked that his mouth couldn't close, and he turned woodenly to Roy. "Is, is it true?!"

Roy nodded silently.

Shocked by the overly terrifying reality, Saitama stood still, dumbfounded.

"Scared, huh? But it's too late now! No matter how you beg, I won't let you off!" Apart from Roy and Saitama, who were shocked by what Carnage Kabuto said, it showed a bloodthirsty smile and launched its attack at an incomprehensible speed. "Die!"

Carnage Kabuto possessed astonishing physical qualities.

Its favorite thing to do in battle was to either sneak behind the opponent at a speed it deemed unreachable or launch an attack directly to the front in a taunting manner.

Since the corridor was too narrow for it, Carnage Kabuto directly unleashed a punch of millions of tons, aiming straight at Roy and Saitama.

"Today is supermarket sale day aaaaahhhh...."

Saitama grimaced as he swung his fist, directly turning Carnage Kabuto, who had thought to himself I've won, now no one in the world can stop me! into sauce.
