"Hello, I sense you are very powerful. Could you spar with me later?"
Goku momentarily forgot about the Dragon Balls, only wanting to test his skills against this powerful opponent.
Even though he might not be able to win, it was precisely because he couldn't win that he needed to fight, to find his weaknesses, and to improve.
The Ancient One paused slightly, then smiled:
"Of course, but I'm not actually that powerful. There are far more powerful people in this world than me."
She wasn't lying about that.
She could thoroughly fleece those dimensional demons and even keep them outside their dimensions.
This wasn't just due to her own strength; more importantly, it was the support of the three Sanctums and her powerful backing.
Whether it was the Trinity of Vishanti or Eternity, one of the five primordial gods, they were not people ordinary dimensional demons could afford to offend.
In a one-on-one fight, her strength was roughly equivalent to Odin after he left Asgard.
Odin had the support of the entire Asgard; she was no match for him. Similarly, if Odin came to Earth, weakened by her use of the three Sanctums, he would also be no match for her.
"Grandpa Odin said the same thing. I will train hard and try to spar with them in the future!"
Goku's face was full of anticipation upon hearing this.
The Ancient One's smile widened; she liked this child more and more.
Although so far, she still couldn't tell which dimension this child came from.
But based on the future she saw with the Time Stone, as long as this child exists in the future, Kamar-Taj and the entire Earth will be wonderful.
That's why she specifically kept a Dragon Ball, wanting to meet this child.
"If you're interested in them, I can introduce you to them first. That way, when you're strong enough, you can spar with them properly."
"Great! Great!"
Goku nodded eagerly.
He was worried about not finding any powerful fighters later, so getting to know them beforehand would be ideal.
"But they're all a bit temperamental, so we'll just take a look from afar, say hello, and come back."
Ancient One blinked.
Goku nodded again.
"Then let's go!"
Ancient One stood up, reached out and took Goku's hand, then stepped forward, already passing through the dimensional barrier and entering the tunnel of light.
Soon, they arrived in a pitch-black space.
"Look, that's Dormammu, a wicked guy who likes to devour universes everywhere."
Goku looked up, and in the endless darkness ahead, a gigantic face appeared.
That face was larger than an ordinary planet, and contained a terrifying dark power far exceeding Zeref's.
He seemed to have noticed Ancient One and Goku's presence, and his face immediately showed anger.
But before he could attack, Ancient One, with Goku, stepped forward again, entering the tunnel of light.
This time, they appeared in a world shrouded in flames, below, countless souls wailed.
At the highest point of this fiery world, a demon draped in a blood-red cloak sat atop a throne of piled bones.
"Mephisto, the Lord of Hell, is an extremely cunning fellow.
If you ever spar with him, just start fighting. Don't let him speak."
Goku looked up at the fanged figure above, feeling a threat no less than that posed by Dormammu.
Mephisto, on his throne, looked down at the Ancient One and Goku, a look of surprise in his eyes.
Especially when he saw Goku wave at him.
In the blink of an eye, the two vanished again.
"That's the Eye Demon Shumagras, a member of the Great Old Ones, evil, ancient, and powerful."
"That's Nightmare, the ruler of the Dream Dimension. When fighting him, be careful not to get pulled into a dream."
Having toured the infinite multiverse and different dimensions, Goku witnessed all sorts of dimensional demons.
Feeling the power of those dimensional demons, his heart was filled with immense excitement.
This world still had so many powerful beings, so many opponents to challenge.
Unfortunately, his strength was still far from sufficient.
Training, Training, Training—he needed to train even harder in the future, to adventure and fight in more worlds.
Once he had enough strength, he would challenge all the masters he had met today.
"What a strong-willed child!"
Back in the antique hall, the Ancient One watched as Goku, far from being frightened, became even more excited and determined. A sigh escaped her lips.
"Whenever you feel ready to challenge them, come find me anytime, and I'll send you there.
Or, if I'm gone, my successor will also send you there."
"Thank you, you're such a kind person!"
Goku's goodwill towards this bald female sorceress increased by one, one, and another.
The Ancient One looked at Goku and smiled: "I should be thanking you."
If Goku could grow strong enough to crush those dimensional demons, so that they would never dare to invade this world again,
Kamar-Taj would have a much easier future.
Of course, Goku was still far from that level, but seeing the future through the Time Stone, she felt he still had potential.
"Here you go, this is yours."
The Ancient One handed the Dragon Balls on the table to Goku.
Goku thanked them again and placed the last Dragon Ball into the box, completing the set of seven Dragon Balls once more.
However, he didn't chant the incantation to summon Shenron.
Instead, he planned to follow Dumbledore's advice and bring the Dragon Balls back to his own world.
He wouldn't take the Dragon Balls to other worlds unless absolutely necessary, to prevent any petty gods from bringing unexpected danger.
Actually, it wasn't entirely impossible; Dumbledore offered a compromise.
Except for wishes like resurrecting the dead that must be fulfilled in this world, other desires could be granted in his own world.
For example, Zeref's curse.
If possible, he could bring Zeref to his world, wish for the curse to be lifted, and then he wouldn't have to worry about Death God's revenge.
This included bringing Mavis's soul and body to his own world, and also using the Dragon Balls to revive her and remove the curse.
However, if he did that, he definitely wouldn't be able to return to the Fairy Tail world.
Zeref and Mavis didn't want to leave the Fairy Tail world yet, so they didn't implement such a plan.
"So, shall we spar now?"
Seeing Goku put away the Dragon Balls, the Ancient One didn't covet the Dragon Balls in Goku's box.
"Yes! Yes!" Goku's eyes immediately lit up again.
