When a science PhD travels to Hogwarts, he discovers that magic is just another form of energy—as long as there is a theory, it can be quantified, copied, and enhanced!

From analyzing the structure of wands to developing magic circuits and energy arrays, he ushered the wizarding world into the "era of technological magic."

Voldemort was sent to the research institute by him, and Dumbledore asked him to give a public lecture on "Magical Physics".

However, this was just the beginning—when he broke through the dimensional barrier, new worlds began to emerge:

In Middle-earth of The Lord of the Rings, he single-handedly suppressed Sauron;

On the continent of The Witcher, he combines magic and runes through alchemy;

In the Marvel Cinematic Universe, he even got Tony Stark to come and get inspiration from him;

After Harry Potter, he will eventually become the supreme god of magic in all the heavens and the myriad worlds!

Traveling through the world of Harry Potter, Howl Weasley awakened the "氪金" system. As long as he had Galleons, he could continue to become stronger.

Others rely on hard work to study, but Hall relies on Galleon.

Others rely on their understanding to learn, but Hall relies on Galleon.

Others rely on talent to learn, but Hall relies on Galleon!

As long as you are willing to pay, you can destroy Malfoy, Black, and Lestrange.

As long as the money is paid, even Dumbledore can kill him.

Since then, the reputation of a "money-making madman" has quietly risen in Hogwarts.

Mysterious man: "I heard you are very powerful in magic, kill someone for me."

Hall: "One hundred Galleons."

Mysterious Man: "Here... help me kill Voldemort."

Hall: "Who?"

Mysterious man: "Are you scared?"

Hall: "You have misunderstood. That is the last bloodline of Slytherin, the great leader of the Death Eaters, the legendary Dark Lord, and the undead with seven clones!"

"This money is not enough..."

"I really want to be naughty." Said Aiden Prewett, the descendant of a famous dragon family, a master of alchemy, a seeker of the spiritual path, a master of everything he learns, a friend of the goblins, and the ultimate king of the deep world.

.......

Aiden Prewett takes the audience through the system to the magic world, and races on the road of exploring the mysteries of magic and climbing to the peak of the soul.

But malice surges from the mind, and the crises buried in the past are always chasing. In the process of fighting against them, Aiden will eventually ascend to the throne of God.

Dumbledore: "I have a weak heart, let me go."

Snape: "You are born evil..."

Erwin, who traveled through time and space to become the only son of a mafia family, relied on the novels and TV series he had read in his previous life to support the crumbling building and pull up the Cavendish family, which was in crisis.

Just thinking about the happy life in the future, the appearance of a white-bearded old man changed everything.

It turned out that this was the magical world of Harry Potter.

At the same time, the necessary gold finger for the traveler has arrived, and you can draw cards by gaining reputation.

[Congratulations to the host for drawing the spell: Levitation! ]

[Congratulations to the host for drawing the spell: Shattered to pieces! ]

[Congratulations to the host for receiving the gold special reward: Magical Animal Affinity! ]

[Congratulations to the host for receiving the purple spell special reward: Unforgivable Curse Set]

..........

The appearance of Erwin is rapidly changing the wizarding world.

Pure-blood family? The wizarding world only needs one noble, and that is the noble Cavendish family!

Hermione: It is the pride of my life to be a vassal of the Cavendish family.

Luna: Dear Mr. Erwin, because of your presence, the wizarding world seems to have regained its glory!

Voldemort had been planning for many years, and when he finally returned, he was stunned.

"Who can tell me why my Death Eaters have now become vassals of the Cavendish family?"

Having been reborn into the world of Harry Potter, Raven only wants to live a happy and joyful life with his family and friends.

So Hogwarts gained a little badger who always acted on his whims.

Harry: Where's Raven? I want to see if he'd be willing to help.

Ron: He seems to have gone fishing in the Black Lake.

Harry: But I just checked the Black Lake, and it's not there!

Ron: Maybe he went to have hot pot with Hagrid? He always says that having a fish hot pot after swimming is very comforting.

......

Dumbledore: Raven, you should continue to create a few more spells so that you have a very good chance of getting a Merlin First Class before your fifth year.

Raven: But Professor, I don't want to continue. I've become more interested in alchemy and fishing lately.

Dumbledore: Your interests are very varied.

Raven: Yes, but I feel like fishing will be a long-term hobby of mine. Those damn fish just won't bite. I think I need to learn some new techniques to deal with them.

......

Grindelwald: You possess the immense talent of Raven, you...

Raven: Sorry, Mr. Grindelwald, I'm not really interested in the greater good.

Grindelwald: But war between wizards and Muggles is inevitable.

Raven: Let the people who should be worried about this worry about it. I'll bend over if the sky falls.

Grindelwald: ......

is in the wrong world?

Hermione dressed as an HP world, but appeared in Marvel.

A mysterious magic book that makes Hermione jump back and forth in the worlds of Marvel and Harry Potter.

……

Tony Stark: It's time to study the Anti-Wizard Warframe.

Hermione: Are you talking about your ragged mantling that was torn down by whom?

Hulk: Roar!!

Hermione: Shut up and be careful I remove your pants...... Except for your weapons!

Ancient One: There are no mages on the timeline......

Hermione: Again, I'm a wizard!

【Reincarnated as Dudley Dursley + Power of Logic & Strength + Fixing Canon Regrets + Power-Up via Magic Item Fusion + Straight Talker (Honest and Open Schemer) + Light System (Low Presence) + No Female Lead】

A bold and street-smart man from Blue Star reincarnates into a parallel Harry Potter world…

…as none other than Harry’s infamous Muggle cousin—Dudley Dursley.

By fixing key regrets in the original story, Dudley earns the right to fuse magical items, cleverly balancing brute force and sharp reasoning, evolving from a simple Muggle into a Concept-Level Archmage.

From there—

The Savior’s dark childhood is lit by a light so twisted it loops back to righteous.

The half-giant’s beloved dream of dragon-riding becomes reality, soaring over the Forbidden Forest.

The sweet-toothed old bee (Dumbledore) stops doing faith leaps from Astronomy Tower.

The prideful little dragon (Draco) embarks on a new path of growth, with friendship taking center stage.

The venom-spitting bat (Snape) is no longer misunderstood, but ends up tasting an even deadlier venom himself.

The pink toad (Umbridge)… actually becomes a literal pink toad.

Hogwarts undergoes sweeping educational reform.

The deeply cherished dead return from beyond the Veil.

And the brutal war that didn’t even spare the birds becomes a one-sided steamroll—with full counterattacks stacked to the max.

It took Samael 11 years of traveling back and forth to realize that he had come to the world of Harry Potter and had become a wandering descendant of the Gaunt family.

What kind of sparks will be produced when Parseltongue meets Anaconda?

What effect will occur when werewolf venom is combined with the blood curse?

What changes will happen when Orochimaru meets the Green Snake with Three Flowers?

Samael Gaunt, a wizard seeking fame and power.

Harry Potter: He was my best friend.

Dumbledore: He is a true Slytherin.

Snape: He might be the third Dark Lord.

Hagrid: We have the same hobbies.

At first, Ian was desperate to travel through the apocalypse...

Until he found out he could get into Hogwarts and become a wizard.

As the only transcendent, he said that the end of the world is really fragrant, and a whole world of resources is waiting for him to develop and control.

Potion? Alchemy? It doesn't matter if you fail, just use resources to smash it all out.
