Invincible! This person has lived for a billion years

William was about to greet the Sea God Poseidon when he appeared.

Zeus also materialized in front of him.

"Zeus, we meet again." William greeted him with a smile.

William and the Sea God Poseidon had always been on good terms, with Poseidon being more easy-going, while Zeus was somewhat more reserved.

"William the Obliterator!" Zeus stared at William, a flash of severity in his eyes, and commanded in a low voice, "Come in!"

William looked at him puzzledly, sensing that Zeus wanted to pull him into his domain.

But he didn't want to go.

Then, nothing changed.

The severe look in Zeus's eyes vanished, replaced by confusion and shock.

The domain of a high-ranking divine king was fully activated, yet William remained unaffected.

This was the domain of a high-ranking divine king!!

William said, "If you have something to say, just say it. Poseidon is not an outsider."

The Sea God Poseidon looked at his brother sideways: "Brother, that's quite the spine!"

He understood that Zeus had intended to pull William into his domain for a proper fight.

Such a thought indeed showed some backbone.

The Sea God Poseidon had always been unclear about how powerful William really was and who he was exactly. Ever since he saw the stele in the New York City Museum, his curiosity had only deepened.

If the inscriptions on that stele were true, then after they, the three brothers, defeated Cronus, it was William who divided Cronus's power into three parts, giving them to Poseidon and his brothers.

That meant, in front of William, the three great gods would have to call him uncle.

...

Zeus was also immensely shocked inside. When William had beaten him before, he hadn't felt him to be this strong.

"I... indeed, it's been a while since we've seen each other. I've missed you, William. Where have you been all these years?" Zeus was genuinely prepared to concede to reality.

"Ha!" The Sea God Poseidon laughed out loud, giving Zeus a strange look.

"I haven't gone anywhere, just wandering around out of boredom." William considered himself quite the conversationalist.

After all these years apart, he was also curious about what Poseidon meant, "What did you mean by 'spine' just now?"

Poseidon smiled at Zeus and said softly, "Brother, where's your spine?"

Finally, Zeus couldn't hold back any longer, gritting his teeth, he said, "William the Obliterator, enter my domain. I want to have a proper fight with you."

William suddenly understood what Poseidon meant by 'spine.'

His smile grew even stranger, enjoying the situation as Poseidon stirred things up from the side.

"A domain, huh?" William said, "How about this, both of you come into my domain!"

As soon as he spoke, Poseidon and Zeus felt the world around them change dramatically, with all cosmic laws disappearing, leaving nothing but void around them, and only William in front of them.

William rubbed his hands together and said, "I see you're both getting on in years, you need to stretch your muscles!"

Poseidon was shocked and said, "William, I didn't say I wanted to spar with you."

William laughed, "But I want to spar with you! Two is a spar, three is fun."

Zeus tried to use his divine powers, only to find that after being forcibly pulled into William's domain, he was as powerless as a mortal.

As for his high-ranking divine king's domain, it couldn't be activated at all.

William punched Poseidon in the stomach, chuckling, "Spine, right?"

Poseidon was torn between laughter and tears: "I never said I had any spine. It was my brother who said that."

"You're full of tricks too!" William, still not satisfied, hit him a couple more times and then kicked him over.

Zeus, watching from the side, suddenly shouted at William, "Master! I was wrong!"

William was taken aback, asking, "What did you call me?"

"Master, I remember now, you are our master!" Zeus said, "I remember when we were kids, and you did this to Poseidon, you said the same thing. And this feeling, I remember it now."

William quickly regained his composure and said, "Calling me master won't help!"

Then, he unleashed a flurry of blows on Zeus as well.

Talking about spine in front of him?

And even trying to pull him into a domain for a duel.

How could their relationship improve without giving him a good beating?

Zeus has also fully realized the situation just now.

William the Obliterator was always shrouded in mystery, but logically, in their realm, they, the three high-ranking Olympian gods, were supposed to be the strongest beneath the Cosmic Entity. However, when William's domain was activated, their divine powers were nullified.

The only one capable of doing this must be their even more mysterious master from the past.

The Sea God Poseidon also had an epiphany. With Zeus's words, everything suddenly made sense to him.

When they were very young, a mysterious master had taught the three brothers how to use their divine powers.

...

With this realization, everything became clear.

Why William was so powerful.

William's remark "Calling me master won't help" wasn't a denial, was it?

Not denying it meant he was acknowledging it, right?

"Master, we've missed you!" After being beaten, Zeus actually hugged William's legs and cried out.

William, however, didn't know how to continue.

It was like a child being naughty, getting a spanking, and then hugging his legs crying. Could he continue to hit?

It didn't feel right to go on.

The Sea God Poseidon also straightened his clothes and respectfully said to William, "Master."

Seeing his brother behaving so formally, Zeus instantly felt he had acted rashly, let go of William's legs, took a couple of steps back, and respectfully called out, "Master!"

William never expected they would find out.

Back when the three brothers were children, he hadn't really taught them much. They were naturally talented, but their powers were somewhat weak in the world of the gods at that time. Considering they were Cronus's children, William decided to act as their master and took care of them for a while.

As for teaching them anything...

He felt he hadn't really taught them much.

"Alright! I'm not your master," William waved his hand, opting for a firm denial, and swiftly changed the subject, saying, "If you two have the time, could you take that little girl in the room as a disciple?"ʀᴇᴀᴅ ʟᴀᴛᴇsᴛ ᴄʜᴀᴘᴛᴇʀs ᴀᴛ ɴo(v)elFɪre.ɴet

Zeus and Poseidon exchanged glances, and Zeus asked, "Which one of us does the master want to take her as a disciple?"

William said, "If you're free, both of you teach her. Consider her your joint disciple."
