"I'm full!"
Half an hour later, Goku rubbed his bulging belly, his face full of satisfied smiles.
In all these days, this was one of the few times he had eaten his fill.
Crucially, the food also tasted very good.
This made him feel very favorably towards Hogwarts and Dumbledore.
"Goku, can you tell me where exactly you came from?"
Seeing that Goku had eaten and drunk his fill, Dumbledore began to formally converse with him.
"Mount Paozu."
Goku, of course, held nothing back. He answered whatever Dumbledore asked, without any concealment.
"What was that power you used just now to destroy the roof of the Great Hall?"
"That was the Kamehameha, a technique created by Grandpa Master Roshi."
"Who is Master Roshi?"
And so, through this question-and-answer session, Dumbledore quickly gained a more detailed understanding of Goku's situation.
This also plunged him into deep thought.
With his mastery of mental magic and life experience, even without using Mind Reading, he could confirm that Goku was not lying.
However, what Goku said made him feel incredible, as if it were something that happened in another World.
Having lived for over a hundred years, he had been to every part of the World, even China.
So he could confirm that the World Goku experienced was not his current World.
Rufus believed that Goku had accidentally touched a Portkey, causing him to travel from China to Knockturn Alley.
This judgment was incorrect.
What Goku accidentally touched was not a Portkey, but an item with a similar function to a Portkey, only with a much longer range of teleportation.
muggles have always researched the starry sky and the Universe, believing that other alien civilizations might exist beyond Earth.
They, as wizards, also had similar research.
In the Department of Mysteries at the Ministry of Magic, there was a Planet Room specifically for studying the Universe and Planets.
Goku might have been transported from his own Planet to their Planet.
Or it's possible he entered their Universe from an entirely different Universe.
There are still too many unsolved mysteries in this World; no one can truly say what the real facts are.
Besides Planets, the Department of Mysteries also researches brains, time, prophecy, death, and love.
Each of these is a power that current wizards cannot fully master.
"You said that if you gather seven Dragon Balls and summon the Dragon God, you can truly revive a dead person?"
Taking a deep breath, Dumbledore looked up at Goku and asked the question he cared about most.
As he asked this question, his hands were trembling unconsciously.
"Of course, Upa's father was revived by me after collecting the seven Dragon Balls and summoning the Dragon God."
Goku gave an affirmative answer.
In Dumbledore's mind, the scene of Goku summoning the Dragon God and reviving a man instantly appeared.
"It's true, it's actually true, it really can revive the dead..."
As Goku answered, he secretly used Mind Reading and saw this part of Goku's memory.
He would not use Mind Reading to peek into others' memories unless absolutely necessary.
However, that answer was too important to him, so important that he slightly lowered his standards.
The most painful and regrettable thing in his life was causing the death of his sister, Ariana.
He had always wanted to revive his sister, even contemplating using the Resurrection Stone, even though he knew that what the Resurrection Stone revived might not be his sister.
So if the Dragon God could truly revive his sister, he would be willing to pay with his life.
"Mr. Goku, if I want to summon the Dragon God to revive my sister, is that possible?"
Dumbledore looked at Goku with expectant eyes.
Goku nodded:
"Of course, but the Dragon Balls can only be used once a year, and I promised to revive the soldiers who died because of me.
So if you need them, you'll have to wait until the year after next to collect and use the Dragon Balls."
"It's alright, I can wait a few years, as long as I can revive my sister before I die, that's enough."
Dumbledore's eyes couldn't help but well up; he felt that this time he truly saw hope for his sister's revival.
At the same time, his heart was filled with gratitude towards Goku.
"Then, can we start our duel?"
Goku stood up from his chair. Having eaten and drunk his fill, it was the best time for a battle.
Dumbledore also stood up:
"We can start, but we need to go to a more suitable place."
Given the power Goku displayed in the Great Hall, he was afraid that fighting at Hogwarts would destroy the entire school.
"Fawkes!"
At Dumbledore's call, the ancient phoenix Fawkes flew from a high gilded perch behind the door to hover above Dumbledore's head.
"Apparition!"
With a flash of flame, Dumbledore took Goku from the Headmaster's office on the eighth floor, instantly Apparating to the huge Quidditch Pitch outside the castle.
Apparition is impossible within Hogwarts, even for him.
However, with the power of the phoenix, he could overcome this restriction.
"Begin!"
Dumbledore drew his Elder Wand.
Besides fulfilling Goku's request, he also wanted to see Goku's true strength in this duel.
Combining the battle he saw in the hall earlier with Goku's description, he already had some idea in his mind.
But he still needed to try it himself to know for sure.
"Here I come!"
Goku clasped his hands in a bow, adopted the Turtle School's starting stance, and with a flash, charged towards Dumbledore.
His speed was so great that ordinary human eyes could no longer clearly see him.
"Path of the Fire God!"
Dumbledore also couldn't see Goku's body; Goku's current speed was much faster than it had been in the castle.
However, as a top-tier Mind Reading master, he didn't need to see with his eyes; he could easily sense Goku's location with his mental power.
So he raised his hand and cast a large-area flame magic.
Given Goku's speed, ordinary targeted spells, even the most terrifying Curse of Slaying, would be useless.
Because they simply wouldn't hit him.
Only this kind of large-area magic could restrict Goku's speed.
Indeed, facing the wall of fire rushing towards him, Goku chose not to confront it head-on but instead leaped over the sea of fire, intending to launch an attack from the air.
But the sea of fire was not static. Dumbledore gently waved his wand, and countless fiery ropes sprang from the flames, instantly trapping Goku.
If it were a wizard, even one of the caliber of Snape or Professor McGonagall, being bound by Dumbledore's fiery ropes would essentially be the end of the fight.
But Goku was not a wizard; he was a martial artist who used Ki as energy.
With a loud shout, his body erupted with Ki, forcefully breaking free from the flames, and in mid-air, he unleashed his ultimate move directly at Dumbledore:
"Kamehameha!!!"
His intuition told him that Dumbledore was an opponent worthy of his full power.
"Super Shield Charm!"
Three thick layers of magic defensive shields appeared in front of Dumbledore, but they didn't block the terrifying Kamehameha; they merely slowed it down slightly.
Fortunately, Dumbledore had already witnessed the young Goku use Kamehameha with his feet in the Great Hall, so he was prepared.
Therefore, after the Kamehameha continuously broke through three layers of Shield Charms, Dumbledore had already Apparated away from his original position.
"Boom!"
A huge explosion reverberated through the heavens and earth.
Dumbledore, floating in the air, couldn't help but twitch his lips as he looked at the completely vanished Quidditch Pitch below.
The power was somewhat beyond his expectations.
He had originally thought that blowing off the roof of the Great Hall was already very powerful, but he hadn't expected that wasn't his full strength.
If he had taken it head-on, he felt that even if he used all his defensive magic spells, he wouldn't be able to block this one attack.
Currently, no magic in his mind had destructive power comparable to the Kamehameha that young Goku had just unleashed.
An Explosion Spell could destroy a street, but that was because buildings easily collapsed, not because its destructive power was truly strong.
If an Explosion Spell were used on the Quidditch Pitch, it would at most create a not-too-deep pit.
The Fiendfyre Curse, in Grindelwald's hands, could burn down a city, but that would take time to burn slowly, allowing the Fiendfyre to spread outward.
It wasn't a case of one Fiendfyre Curse instantly reducing an entire city to ashes.
However, young Goku's Kamehameha was different; it instantly obliterated the entire Quidditch Pitch, leaving only a giant crater.
"Found you!"
Just as Dumbledore was astonished by the destructive power of young Goku's Kamehameha, young Goku's figure had already appeared behind Dumbledore.
He had known before that the wizards here could teleport.
So, seeing that the Kamehameha missed its target, he immediately landed, his eyes quickly searching for Dumbledore's location.
Upon finding him floating in the air, he immediately pushed off with his legs and appeared behind him.
"Illusion Punch!"
Countless fists rained down on Dumbledore.
But just as the fists were about to strike Dumbledore, young Goku's expression suddenly became dazed, and Dumbledore once again vanished.
"Confundus Charm!"
Sensing young Goku approaching, Dumbledore first cast a Confundus Charm, then immediately Apparated away.
"Dodon Ray!"
After recovering his clarity, young Goku once again located Dumbledore and then unleashed a Dodon Ray.
Kamehameha consumed too much Ki; if he used it too often, he would quickly run out of energy.
Dodon Ray, however, was much easier.
The easiest was still to attack with his fists and feet, but Dumbledore could teleport, so he had to use Kamehameha and Dodon Ray to suppress him to get close.
"Super Shield Charm!"
Dumbledore once again used a triple Shield Charm, and although it still didn't fully defend, it was much better than defending against the Kamehameha before.
Because of the Shield Charm's delay and weakening effect, he didn't need to use Apparition to dodge; he could evade it himself.
This gave him time to immediately launch a counterattack.
His Apparition could almost be instantaneous, but the entire process of Apparition was not comfortable.
It was like his body was forcibly squeezed into a rubber tube.
It didn't matter when he was young and strong, but as he got older, using it too much would take a toll on his body.
So, for him, it was better to use Apparition as little as possible in combat.
"Thunderous Explosion!"
Facing young Goku's renewed assault, Dumbledore waved his wand, and a wide-area explosion directly blasted young Goku away.
Unfortunately, this level of damage could only cause young Goku pain, but it couldn't truly injure him.
Young Goku flipped over and charged at Dumbledore again, simultaneously using multiple Afterimage Techniques to confuse him.
"Whirlwind Surge!"
Small tornadoes formed around Dumbledore, breaking through the multiple Afterimage Techniques.
The tornadoes couldn't harm young Goku, but they would affect his movement speed, preventing him from using Afterimage Technique.
"Impedimenta!"
As Dumbledore waved his wand, young Goku felt his movement speed decrease again.
As the Wizarding World's recognized most powerful wizard, Dumbledore, though he disliked fighting, did not mean he was not good at it.
He was an all-around wizard, proficient in all aspects.
Through the previous probes, he had already grasped young Goku's general situation.
In his opinion, young Goku was like a fire dragon, possessing powerful offense and defense, and normal magic simply had no effect.
Crucially, young Goku's body was also small, unlike a fire dragon, which was easy to hit.
So what he needed to do now was first slow down young Goku's movement speed so that his magic could hit young Goku.
Only then would he have a chance to gradually subdue young Goku and win this duel.
For this duel, he personally had no desire to win or lose, but for the sake of the subsequent plan, he had to win.
Young Goku's weakness was obvious: his resistance to mental magic was not very strong.
As long as he could hit young Goku with the Stupefy Curse a few more times, he could win this duel.
"Kamehameha!!!"
Unfortunately, before he could cast the Stupefy Curse, young Goku's battle instincts had already sensed danger, and he once again unleashed a powerful Kamehameha.
Facing the Kamehameha, Dumbledore could not withstand it and could only Apparate to dodge.
The Whirlwind Charm and Impedimenta failed, and young Goku returned to his normal movement speed, continuing to search for Dumbledore's location.
But this time he didn't find him.
Dumbledore could not Apparate too far; although a greater distance was safer, the magic's effect and hit rate would greatly decrease.
So, after Apparating, he immediately cast an Illusion Charm to conceal himself and quietly approached young Goku.
"Stupefy!"
A blue light shot out from less than half a meter away from young Goku.
At this distance, if unprepared, even with young Goku's speed, it would be difficult to dodge.
And once the attack succeeded, with his brain in a dazed state, Dumbledore would continuously fire Stupefy Curses until young Goku was completely unconscious, before he could react.
However, he miscalculated.
"Found you!"
The moment the Stupefy Curse was fired, young Goku, as if knowing in advance, actually turned his body to dodge the attack and, with the momentum, delivered a whip kick to Dumbledore behind him.
He couldn't see Dumbledore after he became invisible, but his sense of smell and hearing were far superior to Superman's.
So he could smell Dumbledore's scent and perceive the faint sounds Dumbledore made when moving.
He just pretended not to see him, only counterattacking the moment Dumbledore approached and launched his attack.
The previous battle had already made him understand that if the distance wasn't close enough, it would be difficult for him to attack Dumbledore before Dumbledore used Apparition.
In terms of combat, he was never lacking in wisdom.
"Confounding Charm!"
Just as Goku's leg was about to strike Dumbledore, Dumbledore instantly cast another Confounding Charm.
Due to the Confounding Charm's effect, Goku's attack was interrupted.
This time, Dumbledore did not Apparate away again; instead, he waved his wand repeatedly, casting one Sleeping Charm after another.
Goku, who had just overcome the Confounding Charm's influence through sheer willpower, immediately felt an overwhelming wave of drowsiness wash over him.
He knew this was magic Dumbledore used, just like the Good Boy's Sleepy Sleepy Fist Grandpa Jackie Chun used at the World Martial Arts Tournament.
"Can't sleep! Can't sleep!"
Despite his best efforts to stay awake, he eventually closed his eyes and collapsed to the ground.
"Whew, I finally won."
Seeing Goku finally fall, Dumbledore couldn't help but wipe the sweat from his forehead.
Even when facing Grindelwald and Voldemort, he had never fought so exhaustingly as he did today.
Because he basically understood the magic of Grindelwald and Voldemort, they countered each other's moves, and it came down to whose magic was superior.
Except for the Curse of Slaying, there would generally be no one-hit fatal situations.
But Goku was different from them; if he was hit even once, whether by a close-range attack or a Ki blast, Dumbledore couldn't withstand it.
Goku had great combat talent, but Dumbledore had also never been defeated in this World.
To be honest, he still had some forbidden magic he hadn't used.
"Where is he?"
Just as he was about to lift the Sleeping Charm on Goku, Goku's body suddenly vanished.
And with his magical prowess, he actually couldn't figure out how Goku had disappeared.
However, very quickly, a thoughtful expression appeared on his face.
Goku had said before that he came to their place after falling asleep and encountering a door.
So he guessed that Goku's disappearance now was likely because he had fallen asleep due to his Sleeping Charm and returned to his own World.
"Please, please come back!"
"Dean, what's going on?"
Just then, a black smoke flew from a distance and landed beside Dumbledore.
It was Professor Snape, the Dean of Slytherin.
He looked at the entirely vanished Quidditch Pitch and was almost dumbfounded.
The battle between Dumbledore and Goku caused such a huge commotion that the Professors and students having dinner at Hogwarts naturally felt it.
However, within the Hogwarts grounds, Professors couldn't Apparate and could only rush over on foot.
Professor Snape, mastering flying magic, was one step faster than the other Professors.
"Nothing, I was just dueling with that child, and now the duel is over."
Dumbledore explained.
Snape was stunned by the words; he immediately realized that Goku hadn't used his full strength in their previous battle in the Great Hall.
Otherwise, with the current state of the Quidditch Pitch, the entire Hogwarts Castle would probably be destroyed.
"Did you win?"
"A narrow victory."
Dumbledore said with some emotion; it was indeed a narrow victory.
"Where exactly is this child from, to possess such terrifying strength?"
Snape's eyes widened again upon hearing this; even Dumbledore only had a narrow victory, so how terrifying must that strength be.
The key was that he was still so young; it was simply incredible.
"Where is he?"
"He left for now, but I believe he should be back tomorrow."
Dumbledore stared at the spot where Goku disappeared, silently praying in his heart.
While the two were talking, Professor McGonagall and other school teachers also rushed over.
"Let's head back to school; I have something to discuss with you all."
Dumbledore waved his wand, and with his power alone, he repaired the entire Quidditch Pitch with a Repairing Spell.
If Goku could return tomorrow, then his plan could begin.
Tonight, he would give the school teachers a heads-up.
The next day, Goku slowly woke up in the White space.
"I lost. Grandpa Master Roshi was right; there are many powerful experts outside, and I still need to go to more places and train harder!"
At the World Martial Arts Tournament, he lost to Grandpa Jackie Chun.
At Korin Tower, he almost died at Tao Pai Pai's hands initially.
In Baba's tournament, his weakness was exploited by Grandpa.
And in this duel, even at his best after eating his fill, exerting his full strength, he still lost to Dumbledore.
"I really want to learn the wizards' techniques. I wonder if Grandpa Dumbledore is willing to teach me."
Standing up, Goku once again came to the door with "Harry Potter" written on it.
He wanted to learn any technique that could improve his strength.
So he planned to go back to Hogwarts to find Dumbledore, request to learn Dumbledore's techniques, and then spar with Dumbledore.
Once he could defeat Dumbledore, he would begin the next stage of his journey.
Pushing open the door, his figure appeared on the Quidditch Pitch outside Hogwarts Castle.
"Good morning, Grandpa Dumbledore!"
Seeing Dumbledore standing in front of him, Goku raised his hand and greeted him politely.
"Good morning, Mr. Goku. Would you like to have breakfast together?"
Seeing Goku appear again, Dumbledore finally breathed a sigh of relief.
In fact, after his meeting with the school teachers last night, he hadn't slept at all, waiting here all night, and finally, Goku appeared.
"Food, that's great!"
At the mention of food, Goku's mouth immediately watered.
Dumbledore summoned a phoenix, which, amidst flames, took Goku back to the Headmaster's Office.
As he tapped his finger on the table, a large amount of delicious food immediately appeared on it.
"Wow, how did you conjure so much food all at once? Is this also your magic?"
Goku looked at the table full of delicacies, a curious expression on his face.
He had noticed it yesterday, but his mind was focused on the impending duel, so he hadn't asked in detail.
If he could learn this technique of conjuring food out of thin air, he wouldn't have to worry about going hungry in the future.
"This isn't food I conjured with magic; it was made by the house-elves and brought here."
Dumbledore smiled and shook his head:
"However, if you want to conjure food with magic, it's not impossible.
As long as you master advanced Deformation Curse, you can transform other things into any delicacy you desire.
But this transformation process needs to adhere to Gamp's Law of Elemental Transfiguration; for example, we cannot conjure food out of thin air, but we can transform it…"
Dumbledore rattled on and on, leaving Goku completely bewildered.
Without a magic foundation, he couldn't understand the principles of the Deformation Curse, but that didn't stop him from trying hard to memorize it.
"Want to learn?"
Seeing that the time was right, Dumbledore suddenly asked.
Goku nodded without the slightest hesitation.
"If you want to learn, I can teach you. Not just the Deformation Curse; any magic I know, I can personally teach you, but there's a condition."
Dumbledore paused for a moment, and seeing no expression of aversion on Goku's face, he continued:
"I want to invite you to be our special Professor at Hogwarts, to teach students how to use the power you displayed last night, and to learn your fighting style."
