[OPM: Alright! But how do we do it?]

[Sorcerer Supreme: Don't worry, leave it to me.]

Having said that, he then asks the System on how the [Arena] Function works.

[You only need to tap on a member's profile and there, you will see a word that says [Challenge] and I think you should get the rest.]

"I see." Xyrus then proceeded to did as the System told him. And just like what it said, when he viewed Saitama's profile, he saw the word [Challenge] There and then tapped on it.

Meanwhile, in Saitama's world.

Inside his apartment, he was sitting lazily while staring at the blank space in front of him.

"Why does he take too long?" Saitama complained and before he knew it, a familiar interface appeared in front of him and there, it says.

[One Punch Man has been challenged by Sorcerer Supreme. Accept?]

"Ohhh! It's finally here. Of course it's accept!" Saitama nodded in confirmation.

In fact, Saitama wasn't the only one who saw this. All the members in the group saw the same message and can't wait for the battle to start.

[Prof. Senku: Here it is, I wonder who will win?]

[Anya: Sorcerer-chan will surely win!] Anya expressed her support to her benefactor.

[Iruma: I- I think they're gonna be a draw?]

[Whitebeard: Gurararara, it is finally getting interesting. Though I wish I could also challenge him but my Injury will surely hinder be back, and I'll probably lose.]

[Tony: Oh wow, you have an injury? The strongest man alive has an injury?]

[Whitebeard: Don't worry, even though I'm already sick and injured, I could still make you regret talking like that to me.]

[Tony:....]

[Prof. Senku: How about you guys stop fighting and let's just watch the live stream of the Sorcerer guy.]

In the Livestream, they could see Saitama and Xyrus facing each other while their surrounding was all white, with noo other color can be seen other than white, except for Saitama and Xyrus who were wearing a non-white clothings.

Saitama can be seen stretching his arms and legs, as if he was warming up.

While Xyrus was standing still, waiting for his opponent to make his first move.

After cracking his neck for the last time, Saitama seriously stared at Xyrus, to him this might be the best battle he'd fight so far.

So, without waiting for Xyrus to make a move, Saitama already disappeared from his place, and appeared behind Xyrus with his fist cocked back.

Xyrus didn't let him have the first hit, so he turns around as fast as the lightning, and also cocked his fist.

Soon, both of their fists met each other, and collided. Even though there was still an inch as a gap between their fists, a loud booming sound can be heard already.

*Boom!*

*BoOM!*

*BOOM!*

The more their fist collided with each other, the more the intensity of the explosion sounded.

If there was someone here, then all they'd see was two guys in front of each other while their arms were blurring around.

Not only that, you can even see the shockwaves of the collision of their fists.

Finally, someone was pushed back, and it was unexpectedly Xyrus who looked at his bleeding fist.

He already expected this, after all, physical fight isn't his forte.

Meanwhile, Saitama was grinning madly, he knew that this battle will surely cure his thirst for strong opponent.

[Prof. Senku: I think I'll turn off the scientific side of my brain, since it says that this is scientifically impossible, especially for humans.]

[Tony: Same.]

[Anya: Sup-Sup-chan! Go go go! Defeat that baldy!]

[Iruma: S-Sup-Sup-chan? Are you referring to the Sorcerer Supreme? And please don't call him baldy, it might anger him or something.]

[Anya:.... No.]

[Whitebeard: Gurararara, this fight reminds me of my fight with an old friend.]

[Prof. Senku: Hoh, then this old friend of your must be hella strong if he could contend with someone like you.]

[Whitebeard: Yeah, but he's dead. After he found the One Piece, he turned himself in, and the rest is history.]

[Prof. Senku: My condolences.]

[Whitebeard: Gurararara, not only he found One Piece, but he also started a new era. An Era of Pirates.]

[Prof. Senku: Pirates? Really? And what's this One Piece that you've been talking about.]

[Whitebeard: One Piece.... It is a treasure that resides on the last Island, Laugh tale. It is said to be of unimaginable value, riches that surpassed the world government's. But that's what the rest of the world only knows. Because what lies there isn't all treasures but something else....]

[Prof. Senku/ Tony: What is it?]

[Whitebeard:...... I don't know, after all, I haven't been there.]

[Tony: Damn Old man, don't leave us blueballed here.]

[Prof. Senku: hmm, interesting.]

[Whitebeard: Anyway, enough about me, let's focus on the fight.]

While they were talking about One Piece earlier, Saitama and Xyrus were in a stalemate.

Although Saitama always managed to injure Xyrus whevener their fists collided, Xyrus always healed, much to Saitama's annoyance and amazement.

If his opponent could heal as fast as Xyrus, then Saitama won't have a problem of always finishing his opponents in one punch.

____

Although it looked like Saitama was in an advantage, everyone knew that Xyrus wasn't using his everything.

After all, they've saw him reverse the time, so they assumed that he must be able to control time and such. And not only that, they could see the unfaze expression of him, which shows that he wasn't using his all in this battle.

[Tony: Why haven't he finish him yet?]

[Prof. Senku: I think he wanted to prolong this, so Saitama-san's thirst in battle will fade away.]

[Whitebeard: Gurararara, he truly deserves the rank#1 in the rankings.]

[Anya: Zzz.]

[Iruma: A-Anya-san? I think she fell asleep.]

Meanwhile, Saitama was sweating all over his body, while breathing heavily.

This is the first time he experience exhaustion, he doesn't know how long have they been fighting, but he could clearly feel exhaustion.

"You must be exhausted by now, right?"

"Yeah."

Saitama answered Xyrus's question, before he stopped fighting.

"Well, you might not noticed it, but from the start of the battle, I've been using a rune to slowly transfer your stamina into mine, hence why you're exhausted." Xyrus revealed the reason for Saitama's exhaustion.

"No wonder you're not sweating even a bit." Smiling wearily, Saitama can't believe that he'll lose for the first time, after he became what he is today.

"So, do you admit defeat, or do I make you?" Xyrus said.

"C'mon, I can do this all day." Despite the exhaustion, Saitama's stamina seems to be recovering at a fast speed.

"Interesting." Xyrus muttered while looking at Saitama in shock. He doesn't know where he got all this stamina from, but from what he can see, his whole body's aspects seems to have no end.

It was like, he has infinite strength of something.

"Tell me, Saitama. How did you get this strong?" Xyrus finally can't help but ask him.

Saitama seemed to get serious when he heard his question.

"Do you really want to know the secret to my strength?"

Xyrus leaned forward in seriousness before nodding his head.

'It seems like this is very serious.' Xyrus thought to himself.

[Prof. Senku: Wait wait! Is he really gonna tell us the secret to his strength?!]

[Tony: Seems like it.]

[Whitebeard: Is it perhaps a devil fruit?]

[Prof. Senku: What's a de- you know what, your world is very weird.]

[Whitebeard: Yes it is.]

[Iruma: Everyone, here it is! Brace yourselves.]

[Prof. Senku: I'm just gonna take note of this.]

[Tony: yeah, me too.]

"... The secret to my strength is..."

[Hey, Vsauce. Michael here.]
