With Ope Ope no Mi in Marvel (Resident Evil, Marvel, Harry Potter)

"I thought I could choose the world freely, but it turns out it's all just a matter of luck." Upon truly entering the dimensional space, Daniel Davis understood why dimensional space exploration is considered extremely dangerous.

The concept of a multiverse and infinite universes is not wrong, but most of these worlds are void. Finding a space with life in such a vast number of dimensions depends largely on luck.

"Finally found one." After an unknown amount of time spent in the dimensional space, evading countless dangers, Daniel finally discovered a world with life ahead.

Sizzling.

It was as if he had returned to his early days at Kamar-Taj, learning magic with only sparks flickering in his hands. To open a portal to the world ahead, he would need more time.

"Now I understand why Dormammu had to be summoned to appear on Earth." The barrier of the dimensional space is extremely solid. Theoretically, jumping from one universe to another is very difficult.

Especially for large creatures, breaking through this barrier is nearly impossible. In contrast, smaller creatures can more easily penetrate this barrier, much like the dimensional monster the Guardians of the Galaxy fought at the beginning of the second movie.

"I wonder what kind of world it will be." After finally opening the portal, Daniel immediately crossed over.

"Ah!" As soon as he stepped through, he felt himself falling rapidly.

"Damn." Looking at his position, about a hundred meters above the ground, Daniel cursed inwardly and quickly thought of using a portal to land safely. However, the spell for the portal didn't work. Luckily, he reacted quickly, activating his Ant-Man suit to shrink himself.

Bang.

Around twenty meters from the ground, he felt as if he had hit an invisible barrier, bouncing off it repeatedly before finally landing. Dizzy and disoriented, he recovered and removed his helmet, looking confused at the dark, somewhat dilapidated castle on the nearby hill.

"This is a protective shield." Pressing his hand against the invisible barrier, Daniel was astonished by the pressure he felt.

"Young man, this is not a place you should be." A voice, both unfamiliar and aged, startled him. Turning to the source, he saw a tall, thin old man with long silver hair and a long beard, dressed in a peculiar white robe and holding a strange wooden wand.

"Who are you?" After a moment of silence, Daniel drew a Desert Eagle from his Ant-Man suit before speaking.

"Expelliarmus." The old man pointed his wand at Daniel, and a powerful force disarmed him, causing him to drop his gun.

"I am Dumbledore," the old man finally said.

"Expelliarmus, Dumbledore... is this the Harry Potter world? And that's a wand." The name Dumbledore stunned Daniel.

"Dumbledore, the headmaster of Hogwarts?" After a long pause, Daniel asked.

"This is not a place you should be," Dumbledore said, staring into Daniel's eyes. His wand pointed at Daniel, seemingly ready to cast a spell.

Realizing the situation, Daniel quickly formed a seal with his hands, summoning a golden magic shield two meters in diameter in front of him.

Unable to use portals and facing Dumbledore, Daniel had no intention of hiding his strength.

"Wait, I don't know what this place is. I came here by accident," he said from behind the shield, pulling out another Desert Eagle.

"This is not a place you can come to by accident." Dumbledore's frown deepened as he examined the golden shield, recognizing it as a form of magic unfamiliar to him.

As headmaster of Hogwarts, Dumbledore was highly knowledgeable about magic, but this was something entirely new.

"I made a mistake during a teleportation, and I ended up here."

"I believe you, but this place cannot be exposed. I need to use a Memory Charm on you, just to make you forget about this place." Dumbledore's eyes bore into Daniel's as he spoke.

"Sorry, but I won't accept any memory-related magic," Daniel said, taking out a box and placing a miniature missile on the ground, restoring it to its original size.

"I know I'm not your match, but I'm not without means. You know what this is, right?" He said, cursing his luck internally.

This Harry Potter world was perfect for him, offering magical knowledge that complemented Kamar-Taj's system. While the attack magic might not be powerful, it was certainly fascinating.

But facing Dumbledore right off the bat was unexpected.

"I know, a Muggle weapon, banned by the Ministry of Magic." As someone dedicated to maintaining peace between the magical and non-magical worlds, Dumbledore recognized the weapon.

"I promise not to reveal anything about this place. Let's both just walk away."

"Is that weapon really so powerful that it frightens you?" Another old voice spoke from the side.

Turning, Daniel saw an elderly man with a pale complexion and tattered clothing but an air of dignity, appearing on the other side of the barrier.

"It's a weapon comparable to a large-scale spell," Dumbledore explained to the old man.

"Muggles can now create such terrible weapons. One day, the Muggles you protect will destroy the wizarding world," the old man said, his face darkening.

His words left Dumbledore silent.

"Come in and talk. By the way, I am Grindelwald," the old man said, turning his gaze to Daniel.

"Damn." Grindelwald's self-introduction made Daniel step back.

Now he understood why Dumbledore wanted to erase his memory. This was where Grindelwald, the dark wizard, was imprisoned. Dumbledore didn't want this place's location to be revealed.

Just as Voldemort had Death Eaters, Grindelwald had followers. If this place were exposed, Grindelwald's followers would surely come.

If it were Voldemort, Dumbledore might simply kill him. But Grindelwald was his lover, so he couldn't kill him.

"Alright." After a moment of silence, Daniel agreed to Grindelwald's proposal. With Dumbledore present and no portal available, there was no escape.

Kamar-Taj's teleportation magic has a flaw: in a different world, the dimensional space must be re-established before it can be used.
