Harry Potter:

In 2026, Blue Planet was attacked by monsters from another world. Lin En, who was originally middle-aged, was forced to join the ranks of defending his country. Unfortunately, he was killed in an orc raid. When he woke up, he came to England 20 years ago. Reborn as Andres Mori with a complete set of golden fingers, he had a chance to save Blue Planet. Until many years later, he not only saved mankind but also led mankind to conquer the other world. He was called by humans: Marquis of Paradise Island, founder of Hogwarts, guardian of mankind, conqueror of the other world, and great magician.

(This work is a system-based work. The early stage focuses on building Hogwarts to train wizards. The middle stage allows the trained wizards to integrate into the Muggle world to establish a society where wizards and Muggles coexist. The later stage welcomes the invasion of the alien world and resists and counterattacks. The number of words is determined by the work's performance.)

In the magic world a thousand years ago, he traveled with four teachers for seven years. Ryan found himself back in 1991, back to the orphanage he was familiar with. After three days. He saw a pure white owl flying towards him with a Hogwarts admission letter in its beak. So Ryan knew that he would return to the Hogwarts that was familiar yet unfamiliar to him. "Mr. Ryan Elias." "Dumbledore called you the most outstanding graduate in the history of Hogwarts, the Dark Lord regarded you as his greatest enemy, and the dark wizards called you a wizard destined to be great. For these titles..." "Of course." Ryan answered calmly with the answer that should be given. "I approve of it all." Be it potions, duels, spells, alchemy, the dark arts, or even cooking and pranks. "Of course I will always be the best." Because he...

Adrian Wisen, who traveled to the world of Harry Potter, didn't have any big ambitions. As a professor at Hogwarts, his daily routine is to take care of children, farm, and cause trouble for the elderly headmaster. Everyone who knew Adrian Wisen also knew that he was a kind and amiable wizard. Oh, there is one important thing. Never go near those plants he grows!

The story begins. Ian thought he was just a little wizard with a bit of talent and a simple [plug-in]—as long as he worked hard, he could become stronger.

However, as time passed, he began to realize something.

The teachers guiding him in magic were either legendary powerhouses or figures straight out of myths.

*"Standing before you is the noble Apostle of the Maze, the Co-Spokesman of the Old Dead, and the heir personally chosen by the founder of Hogwarts!"*

What? The noseless monster wants to make a move?

He must have never heard of the original spell recorded on my Chocolate Frog’s Famous Wizards Collection Card!

Dumbledore: *"That spell…!"*

Dumbledore’s expression changed as Ian recited *"Call of the Guardian Spirit."*

Silver-white threads surged, intertwining and condensing until a familiar figure appeared, one that a certain professor had spent his entire life drowning in guilt over.

In the wizarding world, magic only erupts when one is about to turn eleven. Rhine was ready to lie down when he just received the Hogwarts admission letter, until...

[Congratulations to the host for joining the Chan Sect, the Honghuang human connection system is officially bound]

Rhine: "This is Harry Potter, system, are you crazy?"

[Main quest: Make friends, participate in the Battle of the Gods and survive]

Rhine: "I repeat, this is Harry Potter. I'm going to take my head to participate in the Conferred God Battle?"

[In front of you is Yuan Hong, the leader of the Seven Monsters of Meishan. He is a natural species, more than eight feet tall, holding a water and fire stick.]

[Make friends with Yuan Hong to gain the talent - Iron Skin and Iron Bones.] Invulnerable to swords and guns, immune to water and fire, and can extend your life by a hundred years. 】

Rhine fell silent as he looked at the half-blood giant Hagrid in front of him.

"Okay, this is the primitive world, right?"

"I just want to ask, are you authentic?"

At just seven years old, Dina Avery was imprisoned in Azkaban, becoming Sirius Black’s fellow inmate.

On his first day behind bars, he discovered that "Merlin’s XX" wasn’t just an expletive—it was a real summoning ability. He could actually call upon Merlin’s powers, including but not limited to:

- Merlin’s Beard

- Merlin’s Stockings

- Merlin’s Magic

- Merlin’s Bloodline

- Merlin’s Treasure

From that day on, Dina relentlessly “borrowed” from Merlin’s legacy.

Four years later, Dina made history as the first young wizard to receive a Hogwarts acceptance letter while in Azkaban. After being picked up by Snape, he found that his home was gone.

But it didn’t matter. He was Merlin’s heir.

The scum responsible for his family’s destruction would soon face justice—

at the hands of the new Merlin, just like in The Count of Monte Cristo.

The demon moon and calamity stars are coming, the demons and ghosts are rampant, the demons and demons are rampant, and the bloody storm is coming!

Through the story of Draco Malfoy’s twin brother who was reborn as Draco Malfoy and decided to become stronger in order to protect his family!

Hogwarts is the daily text of the main scene, with additional original plots for summer and Christmas holidays. The characters are close to the original description, and try to skip the refined text of the original content. Readers need to read the original

"My name is Tom Riddle. I was born in the Wu Orphanage and I am a wizard."

"I speak Parseltongue well, have a yew wand, phoenix feathers, 13.5 inches, and am in Slytherin."

"My favorite magic is chewing big melons."

"Huh? What did you say? I am Voldemort? Come on, I am so handsome, how could I be that noseless Tom?"

Tom, who traveled through the world of "Harry Potter", entered the wizarding world with the same name as Voldemort and a face that looked like the Dark Lord when he was a child.

Dumbledore: I suddenly feel my eyes are blurry, otherwise how could I dream of going back to 1938.

Lucius: Two masters, I can’t tell them apart. I really can’t tell them apart.

Voldemort: Who am I, where am I, and what shall I do?

Hogwarts: Huh? It turns out the Dark Lord is right next to us!

Tom: I'm really not Voldemort. This is all Noseless Tom's fault.

..........

"Let the magic world surrender to us!"

When Voldemort was madly venting his ambitions on Tom, he was met with a big bite of melon.

"Only losers are Voldemort, and I am Tom Riddle!"
