From the moment Yang Tian was born, he knew he was born into a wizarding family that combined Eastern and Western traditions. It seemed his life was settled; his parents loved him, everything went smoothly, and he lived a life that was both awkward and comfortable.

Unexpectedly, the mysterious and powerful evil organization turned out to be the family's mortal enemy.

Clash after clash, battle after battle...

Yang Tian and Nightmare both moved forward with determination!

But what's with Dumbledore and Snape's wariness and estrangement?

What's with the supposed break in the transmission of magic between the East and the West?

Why is Salok so ubiquitous?

But none of that matters! The support of my family, the help of my friends, the guidance of my teachers...

I will surely be able to fuse Eastern and Western magic, unravel the mysteries of ancient magic, and forge a brand new path!

Snape: This kid has unparalleled talent in potions, but he always substitutes precious herbs with cheap ones that I don't recognize. He's a total swindler!

Dumbledore: Is this kid still using Patronus? Those solid figures, could they be the legendary mythical beasts?

Voldemort: Kid, if you're so tough, don't use those two little pieces of paper, let's have a proper fight!

......

At the top of the world, he and his comrades stood tall.

Forward? Or...backward?

John Shafiq, son of a nun.

As a special wizard who can devour magic power.

From the day he gained power, he knew that the world was full of greed and malice towards him.

For him, Hogwarts was the only refuge in this world.

But the fledglings always have a time to spread their wings.

Even a dormant dragon will eventually rise from the abyss.

When that day comes, what will the appearance of the dragon leaping out of the deep pool be?

[Voldemort, why does your magic taste so bad? ]

PS: The protagonist is a human, not a dragon. Dragon is just a title.

William, an ordinary person, originally thought he would live a plain and uneventful life.

A letter delivered by an owl transported him to a magical world.

Is the protagonist in danger?

William said he didn't have time.

Has Hermione become cunning?

Hmm, and then what?

Dementor Riot?

Now we have the materials!

William never considered himself a freak scientist.

He was just an ordinary, unremarkable scholar.

Luochen traveled across time, came to the world of Harry Potter, and got the wizard supreme system. Although the system is relatively doggy, it is called a ruthless system if it is turned on and hung up. Leveling up is like drinking water, destroying Horcruxes in a few days, crushing Snape in half a year, and rivaling Dumbledore in a year.

When everyone found out that Voldemort had become a woman, and Lockhart had become a big devil, Hogsmeade was not the only one, and the Chinese language was popular all over the world...

Luo Chen has become a god, overlooking all living beings!

Smile lightly: All life in the world is in my palm. Who is more powerful than me in the world?

(The main text has been completed, and the movie-watching extra is being written)

Please don't mind this weird introduction.

After Bai'e and the pioneers offered the "Negative World" fire at the center of the Creation Vortex, his vision went black. When he woke up again, he found that he and his deceased Golden People companions had traveled to a strange world and shrunk to the size of a 10-year-old child!

As for why, just assume it was Aha who did it.

Dumbledore: Savior? Interesting.

Wan Die: Did I say to annihilate Wan Bang Nier Doron? HKS!

Na Ke Xia: Magic↗↘Skills↘!

Bai'e: Harry, why do birds fly?

Harry: ?

Voldemort: Don't come over here!

Xiadie: (smiles slightly)

Having transmigrated into the last bloodline of the Grindelwald family, he initially wanted to live a low-key life, but was forced to bind himself to the "Underworld God System".

From then on, the style of Hogwarts completely went astray.

"Petrify everyone? That's too lame. Come and witness the power of our Zaun petrification!"

"Want to learn the Patronus Charm? First, pay protection money to the system. Avada Kedavra can turn a melon into a rainbow color for you."

Dumbledore looked at the savior, who had been turned into a "henchman," and fell into deep thought: "This kid...maybe he can form the most cowardly villain alliance in history with Tom?"

Until one day, I was cornered by the Dark Lord, and the system suddenly prompted me—"Hey buddy, there's only one guy on the other side, call for reinforcements to take him down!"

Travel through the ruined magic academy, the epic battlefield of blood and fire, and the doomsday scorched earth where demons wreak havoc.

When Zhang Peiran opened his eyes in the cycle of death, the bricks and stones of Hogwarts Castle were being corroded by the Dark Mark, the smoke of war in Middle-earth obscured the brilliance of the Silmarils, and the Eye of Sargeras could be seen on the broken coastline of Azeroth.

Voldemort's power was infused tenfold by the abyss. The Mordor orc army, accompanied by the fallen Maia, swept across the earth, and the Burning Legion's twisted fel warships obscured the entire starry sky.

There is no way to retreat, only hands holding the magic wand and rune sword, walking alone in every world where eternal night is approaching.

(Advance warning: This is a long and endless story with no female protagonist. It focuses on the magic system. The current planned routes are "Harry Potter World", "Lord of the Rings Middle-earth", and "Azeroth World of Warcraft".)
