Dumbledore and Grindelwald (End)

"Grab my arm." Outside the protective barrier of Nurmengard Castle, after Dumbledore had left, Grindelwald said this to Shen Fei.

"Apparition." Shen Fei immediately grabbed Grindelwald's left arm.

He didn't know what had been said between Grindelwald and Dumbledore, but when the two appeared before him, Grindelwald already had his wand in hand. With his wand, this prison naturally couldn't hold him anymore.

In the world of Harry Potter, having a wand versus not having one was like the difference between heaven and earth—even greater than the difference between a Muggle having a gun or not.

After grabbing Grindelwald's arm, Shen Fei felt as if he had entered a continuously spinning space. When he reappeared, he was on the side of a street that looked very ancient. Most of the people on the street wore black robes. A wooden sign on one side told him where this place was: Diagon Alley.

Outside Nurmengard Castle, shortly after Shen Fei and Grindelwald left, a golden circle of light opened silently. A figure in yellow robes stepped out from within. After pushing back its hood, a bald head was revealed—the Ancient One, Supreme Sorcerer. He had actually come to this world too.

Shen Fei probably never imagined such a thing could happen.

Gringotts, the Wizarding World's bank.

After bringing Shen Fei to Diagon Alley, Grindelwald's first stop was here. After presenting identification, the goblin staff at Gringotts immediately became very respectful.

"Vault 444." After passing through a maze of underground tunnels, Grindelwald and Shen Fei arrived at this vault. Grindelwald took out a large number of gold coins—gold Galleons, to be precise.

"Undetectable Extension Charm." Looking at the small bag that had held so many gold coins, Shen Fei immediately guessed what was going on.

This spell was the one Shen Fei most wanted to learn. What impressed him most about the Undetectable Extension Charm was Newt's suitcase. Newt's suitcase was simply incredible.

"Is there anything you want to buy?" After leaving Gringotts, Grindelwald said with a smile.

"A wand." Shen Fei thought for a moment and said this.

In the world of Harry Potter, wizards were entirely a matter of talent—determined from birth. There was no such thing as an ordinary person becoming a wizard.

From the attitudes of Dumbledore and Grindelwald, he was definitely a wizard, not a Muggle.

Whether he was born one or because he had practiced Kamar-Taj's magic, Shen Fei didn't know. But he leaned toward the latter—that it was because of his Kamar-Taj training.

Although Kamar-Taj mages basically fought with blades and fists, when it came to principles, Kamar-Taj's magic was so lofty it bordered on divine power. In this regard, the Harry Potter world, which relied entirely on talent, couldn't compare at all.

Ollivander's Wand Shop was a wand shop with a long history. Most wands in all of England came from here.

Regarding the wands of this world, Shen Fei was very curious about one thing: why didn't people buy several spares?

"He needs a wand." After walking into the shop, Grindelwald said directly.

Hearing Grindelwald's words, Ollivander immediately scrutinized Shen Fei carefully. Then he pulled out a wand from among the many boxes and handed it to Shen Fei.

"This is made of ebony, with a nerve from a Chinese Fireball Dragon. Try it."

Bang.

Taking the wand, Shen Fei felt it for a moment, then casually waved it. An invisible shockwave shot out from the tip of the wand.

Magic didn't always require incantations. Like what Shen Fei had just done, attacks could be launched this way too. This was one of the main methods of combat between wizards. In real battles, it wasn't a duel—no one would give you time to chant a spell. Using such attacks to buy time for casting was the most common tactic.

To put it another way, this kind of attack could be considered a Magic Blast. Since it was pure magic, its power was generally weaker.

Next came magic books. The two went together to Flourish and Blotts.

After thinking it over briefly, Shen Fei directly bought all the textbooks for all seven years at Hogwarts, along with many books on wizarding world history and famous figures.

Although the request was a bit strange, Flourish and Blotts still sold them—probably because of Grindelwald.

Afterward, the two used Grindelwald's Apparition to go directly to King's Cross Station.

Shen Fei was very curious about Diagon Alley, but he could go there anytime later. For now, he needed to show Grindelwald some results from his plan.

Dumbledore and Grindelwald weren't fools. On the contrary, they were among the smartest people in this world. There were many problems in Shen Fei's story, but because of the plan's prospects, they simply pretended not to notice them.

Just like when Shen Fei bought the wand and all the magic books, Grindelwald said nothing.

Speaking of which, these things weren't cheap. His wand cost six gold Galleons—one Galleon cheaper than Harry Potter's wand.

That amount seemed small, but it was actually very expensive. Most people in this world only had one wand in their lifetime, and the price might be one reason.

Look at Ron. His wand broke, and he could only tape it back together, which caused spell rebounds.

Not to mention the prices of those magic books. All the textbooks from first to seventh year cost several times more than the wand.

After leaving King's Cross Station, it was Shen Fei leading Grindelwald. Wizards generally knew very little about the Muggle world, let alone Grindelwald, who had been imprisoned for decades. Even if Dumbledore occasionally told him news from outside, it was mostly about the wizarding world.

"First, exchange money." Before setting out, Shen Fei had brought a lot of gold bars. This could be considered a universal currency across the multiverse. As for why gold—probably, maybe, possibly—it had to do with the properties of gold as a metal.

Gold could not only be used as currency but also as raw material.

Here, he had to thank Ada for teaching him some things beforehand. Otherwise, exchanging money would have been troublesome.

"The technological level of this world is too low." After buying a house in London and roughly investigating the world's technological level, Shen Fei couldn't help shaking his head in disappointment. He had already tried not to expect much from this world's technology, but after actually experiencing it, he was still very disappointed.

"Magic suppressed technological development." The reason for this result was obvious without guessing: magic.

"It seems what I said to Coulson wasn't a lie." Looking at the famous figures in magical history, Shen Fei couldn't help but smile.

Newton, Einstein, and other famous scientists were all wizards. Even the invention of the nuclear weapon was mainly due to wizards.

After reading the basic knowledge of magic, Shen Fei also understood why this situation occurred. Although wizards in this world were basically determined by talent, they were still mages, and they followed one principle: the smarter a person was, the easier it was for them to become a mage.

Later, when talking with Grindelwald about his and Dumbledore's past and that war, Shen Fei suddenly had an idea. Grindelwald and Dumbledore—this pair of lovers-turned-enemies—were too similar to the Red Skull and Captain America.

In this world's World War II, Grindelwald was basically the Red Skull.
