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.

Qi Komo unexpectedly transmigrated to the world of Harry Potter and gained a "Game of Life System." This system allowed him to enter game worlds and, by achieving in-game accomplishments, gain "materialization chances" to bring items from the games into reality.

He loved playing games, but before he could even celebrate, he discovered that the games he encountered were all frustrating ones like Elden Ring.

Fortunately, as a member of the "Wind Spirit Moon Shadow Sect," he had the sect's protection. Whenever he faced a difficult game, he could always find a way to lower the game's difficulty.

And so, Qi Komo lived a carefree life in the Harry Potter world, attending school, playing games, and raising little witches.

Many years later, looking at Hermione, now the Minister of Magic who had defeated both the Dark and White Lords, Qi Komo was filled with emotion.

"Raising" games are indeed the most fun.

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?"

"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!"

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...

On the day he crossed the world of Harry Potter and received the admission notice, Ethan awakened the achievement system. As long as he made the corresponding events, he could get rewards.

With three million gold, he has achieved the achievement of [hegemony and wealth can rival the country].

Get the blood of magical animals and achieve the achievement [I'm not a human].

Use Avadaso's life to kill 100 wizards and achieve the achievement of [Gnawing Big Melon Lover].

......

On the day of graduation, when Ethan was seamlessly appointed Minister of Magic, the reporter of The Prophet's Daily asked:

"Mr. Adrian, as the youngest and best Minister of Magic in history, I heard that you have been famous for Hogwarts in the first year of admission, won the Merlin Order Medal in two years, and directly overturned the professor in three years... I don't know why you have achieved such dazzling results?"

Ethan Adrian spread his hands: "I really want to make progress!"

He was at Hogwarts, and had just become a Half-Blood Prince.

…

In 1976, 16-year-old Severus Snape welcomed a new life.

That year, Voldemort had not yet split his soul into seven pieces.

That year, Nagini was still hiding in the forests of Albania.

That year, Pandora was still doing wonderful experiments at Hogwarts.

That year, Ms. Rosmerta was in her prime and very graceful.

That year, Snape decided to experience this wonderful world.

On this day, the first-year Hogwarts freshman, the young savior Harry Potter, learned that a fifth-grade transfer student came to his college. He asked curiously: "Mr. Linde, where did you study magic before you transferred?"

Linde smiled slightly after hearing this, "I was the chief mage in Winterhold in the first grade, studied pyroxene magic at Rhea Lucaria College in the second grade, and conducted actual combat training in Middle-earth in the third grade. Years went to Candlekeep to build their mage tower at Baldur's Gate."

"That sounds incredible, so what are your plans for this year?"

"If you want to build a floating city, you have to set up your own secret religion. Maybe you can solve a little trouble for Professor Dumbledore by the way? For example, a certain Parseltongue is not very friendly."
