Fourteen years have passed since Matthew traveled to the world of Hogwarts. During his summer vacation, he unexpectedly acquired a metal disc that allows him to travel to another world. This world has a completely different system of magic. The wizards here are not hidden, and even the wizarding organization rules the land. Matthew travels back and forth between these two worlds, merging the two magical systems. He will control his own destiny and even become a god! Matthew will become the driving force of history, bringing tremendous innovation to both worlds! ... (Not systematic, not saintly.)

Evan has time-traveled once again.

His first time traveling was from Earth to the D&D world, where he went through trials and tribulations and became a sorcerer of the Universal School.

However, a fierce battle ended his second life.

When Evan opened his eyes again, he was surprised to find that he had once again traveled to a magical world that was both familiar and strange.

An owl flapped its wings and flew swiftly, delivering his Hogwarts acceptance letter, but the timeline he arrived in was 1971.

In 1971, a turbulent era, the Demon King was stirring, the Phoenix perched high in the castle, and the towers of Nurmengard remained tightly shut.

And those future heroes—Lupin, Sirius, James, Lily, Snape… at this moment, they are just innocent teenagers, unknowingly walking into the vortex of fate.

This is a glorious era, though not detailed in the original work, it is equally magnificent and filled with brilliant stars.

However, for Evan at this moment, the first thing he needs to solve is how to restore his spellcasting ability in this world without a magic network and with scarce magic power.

Or perhaps, he could go even further, relying on more advanced magical research concepts, gathering a group of intelligent and powerful companions, and launching a magical revolution that would change the entire magical world.

In any case, the times are waiting for Evan's actions.

-----------------

The timeline is set in 1971, in the same year as Sirius Black, Lupin, and Snape. The protagonist has mastered the spell system of D&D, has no system, breaks up the original pairings, is slow-paced, not mindless, and will seriously consider the plot.

He traveled to the Harry Potter world with a simplified system. He thought that with the system, he would become the richest man in the world. However, an acceptance letter sent by an owl changed his plan. It turned out that he was not in the city but in the magical world...

I took the letter and looked at the familiar logo on the cover, then looked at the time on the calendar hanging on the wall, and fell into deep thought...

Even though he hated Nanny Wen in his previous life and still hates her now, he doesn't hate others being his nanny!

It’s just that at this point in time...

Well, I can’t rely on the care of the three protagonists anymore, so I can only rely on their parents.

But I didn't expect that I didn't get the thigh, but I became the thickest thigh...

It was also from this day that the world began to emit shrill screams.

Tang: Damn it, who stole my true energy!!!

Yu: "Ahhhhhhhhhhh!!! Oh my god!!!"

Jia Zhang: "Old Jia, please come back and take this thief away!!!"

In short, this is a story about exchanging everything in the Harry Potter world...

Upon opening his eyes, Sean found himself a member of Hollisey's Orphanage. Despite a somewhat bleak start, the magical world he had never imagined was opening its doors to him. Even more delightful, local specialties arrived along with him. "I, Sean, have come this far entirely through my own hard work! Proficiency panel, add points!" From a [Spells Novice] who had just learned the Luminescence Charm to a [White Lord] who had mastered all spells; from a [Transfiguration Apprentice] who could transform matches to a [Magical Legend] who could alter the properties of matter; from a [Potions Novice] who could barely brew a scabies potion to a [Master of the Crucible] who had created an entire potion system. His magical achievements were as numerous as the stars: Transfiguration, potions, spells, the Dark Arts, prophecies, magical creatures, alchemy, astronomy... His life was celebrated by many: Dumbledore, Grindelwald, Scamander... Oh, let's interview the dying Mr. Voldemort; he seems to have something to say. The Dark Lord was kicked to death: "No one told me that there was a White Lord hiding in Hogwarts!" This book is also known as: "A Certain Liver Emperor's Hogwarts", "A Liver Legend of Magic", "Hogwarts: Sorry, I Just Want to Learn"

But some vengeance still needs to be avenged.

Chen Yu, he has many identities.

He is a gamer and a student at Hogwarts.

He is Tony Stark's savior and is also respected as the Second Supreme by the wizards of Kamar-Taj.

He was the victor of the Fourth Holy Grail War and El-Melloi II's student and greatest patron.

He was given the three Unforgivable Curses at the beginning and almost entered Slytherin.

His biggest dream is to explore the magical mysteries of different worlds.

What I want to do most is to fire an Avada Kedavra light cannon at the enemy.

Many years later, Harry Potter, who was hailed as the greatest white wizard of this century after Dumbledore, was interviewed by a reporter.

"Mr. Potter, is the person you respect most Headmaster Dumbledore?"

Harry shook his head.

"Is that Professor Snape?"

Harry still shook his head and said softly, "From beginning to end, there is only one person I respect, and that is my teacher - Al Yaxley."

He came to the magic world with the spark of arcane civilization, vowing to rewrite the fate that was destined to be tragic.

Floating cities rise from the ground, arcane towers connect heaven and earth;

Ancient magic was recast in his hands, and wizarding society was redefined by him.

This is a revolution from low latitudes to high latitudes, and it is the first step for wizards to move towards the sea of ​​stars!

——Voldemort will eventually be destroyed, the savior will no longer walk alone, and he is the one who truly changes the world.
