Hogwarts was also currently in the middle of the night, at roughly the same time as the World of Fairy Tail, around eight o'clock.
Thus, Headmaster Dumbledore was not yet asleep; he was busy studying a diary.
This was no ordinary diary, but an evil Horcrux housing a fragment of Voldemort's Soul.
Not long after the school term began, a major incident had occurred.
The Chamber of Secrets of Slytherin had been opened once again, and Filch's cat, Mrs. Norris, had been attacked and petrified.
Fortunately, the matter did not escalate for long before it was resolved.
Hagrid, who had once been wrongly accused of opening the Chamber, led Harry and the other Little Wizards who practiced Ki to track down the Basilisk that had emerged from the Chamber, using their Ki sensing abilities.
Then, with everyone joining forces—one person firing a Kigong Wave, another a Dodompa—they blasted the Basilisk into smithereens before it could even show its head again.
By now, Hagrid could barely manage to use a Kigong Wave, though its power was still far inferior to that of Goku.
Harry and the other Little Wizards had also mastered the Dodompa, barely managing to release it by converting the magic within their bodies into Ki.
If they relied solely on the Ki cultivated through physical training, they wouldn't have enough to release a Dodompa.
When they found the Basilisk, they also found Ginny, who had been released to open the Chamber, and subsequently discovered Voldemort's diary that had bewitched her.
Through studying the diary, combined with previous conjectures and a vast amount of research, Dumbledore finally unraveled the secret of Voldemort's immortality.
In the books 'Magick Moste Evile' and 'Secrets of the Darkest Art', there was mention of a Dark Wizard from Ancient Greece named Herpo the Foul.
This Dark Wizard achieved immortality by splitting his Soul and attaching the fragments to objects.
Objects created through this evil dark magic are known as 'Horcruxes'.
As long as a Horcrux is not destroyed, the Dark Wizard who created it can return to life through the Soul within it.
This diary containing Voldemort's Soul was clearly one of Voldemort's Horcruxes.
And it was likely not the only one.
It was imperative to find out exactly how many Horcruxes Voldemort had made, locate them all, and destroy them to kill Voldemort once and for all.
"Tom, just how many Horcruxes did you make?"
Dumbledore questioned the diary on his desk.
Words quickly manifested on the diary; it was Voldemort's Soul responding: "Old man, you will never know how many Horcruxes I made.
Because this is my sixteen-year-old Soul—how could the sixteen-year-old me know how many Horcruxes I would make in the future?
Hahaha..."
"In that case, you no longer have any value."
Dumbledore drew the Sword of Gryffindor from the Sorting Hat and pierced the diary right through the center.
Blood immediately oozed from the diary as it let out a piercing scream.
After a moment, the screaming stopped, and the diary crumbled into ash, dissipating into the air.
At that moment, Goku's figure appeared in the office. Seeing Dumbledore holding a sword, a curious look appeared on his face: "Grandpa Dumbledore, are you practicing swordsmanship?"
"Yes, just stretching my old bones a bit tonight."
Dumbledore was a bit surprised to see Goku appear, but he quickly regained his composure and replied half-jokingly.
"By the way, you've come at the right time. I've nearly finished modifying the Animagus transformation magic.
If you are willing, you can begin the Animagus transformation ritual at any time."
"That's great!"
Goku's face lit up with surprise and joy upon hearing this.
If the Animagus transformation could truly turn him into a Great Ape, his strength would be significantly boosted.
The key was that an Animagus Great Ape transformation was different from the one triggered by his tail.
Transforming via his tail required a full moon, and after transforming, he would lose his reason, thinking only of destruction.
But an Animagus transformation didn't require a tail or a full moon; he could transform into the Great Ape form whenever he wanted and revert just as easily.
The most important aspect of an Animagus transformation was maintaining one's humanity, letting the human side master the beastly nature.
So as long as it was successful, there would be no risk of losing his mind.
"Grandpa Dumbledore, let's put the Animagus matter aside for a moment. I need your help to save someone."
Although he really wanted to perform the Animagus ritual immediately, he remembered the purpose of his visit.
"Save someone?"
A curious look appeared on Dumbledore's face.
Goku then quickly recounted all of his recent adventures to Dumbledore.
After listening, Dumbledore couldn't help but sigh with emotion: "magic can actually be used in such a way? It seems our exploration of magic is still too shallow!"
He had no interest in the Breathing Techniques of the demon slayer World.
Although some students at the school were learning Ki Magic from Goku and were already becoming like warriors, as a wizard of the oldest and purest generation, he was still only interested in magic.
The magic in the Fairy Tail World, which was completely different from their own, along with its unique casting methods, truly did attract him.
Coupled with the recent discovery that Voldemort had created an unknown number of Horcruxes and that the future remained fraught with danger, he couldn't help but have a few more ideas.
Perhaps he could use Goku as a medium to achieve a magical exchange between the two Worlds, learning from each other's strengths and progressing together?
Of course, this thought only flashed by; after all, making it happen would be no simple task.
"Since I haven't seen it for myself, I'm not sure if I can break the Seal. You'd better take me there to have a look first."
After a moment's thought, he replied to Goku.
Seeing that Grandpa Dumbledore was willing to help, Goku immediately put him into his box, then leaned against the desk and fell asleep again.
His figure entered the white space once more.
Since successfully taking an owl to the demon slayer World last time, he understood that he could also take people into other Worlds.
But he couldn't take them directly; if he simply pulled Grandpa Dumbledore into a sleep state with him,
Grandpa Dumbledore would be left outside and wouldn't enter the white space with him.
Only by placing Grandpa Dumbledore inside the box made with the Undetectable Extension Charm could he be brought into the white space and thus into other Worlds.
Pushing open the door to the Fairy Tail World, Goku reappeared inside the temple on Galuna Island.
"Goku, where's the helper you mentioned?"
Seeing Goku appear, Gray and Lyon stepped forward and asked anxiously.
In their eyes, Goku had used Teleportation Magic to go somewhere else and had now teleported back.
But since Goku wasn't with anyone else, did that mean he hadn't found the helper who could break the Seal?
"Right here."
Goku opened his box and released Dumbledore, who was dressed in wizard robes and holding the Elder Wand.
