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!"

"Robin, a model citizen, is transported to a magical world, inheriting the bloodline of the Eastern Phoenix from the start! After enrolling at Hogwarts, with his extraordinary talent and the blessing of the Phoenix bloodline, he gradually rises to the pinnacle of the wizarding world, becoming an existence surpassing even the god of magic, Merlin!"

[Slice-of-life story + no female lead + research]

Lin Yi, whose love for astronomy is etched into his soul, is born into the HP world with all the knowledge from his previous life and a super brain that can "remember everything he sees".

He thought he could easily become an academic star in the magical world, but he discovered that wizards' understanding of the brilliant starry sky above them was still stuck in the primitive stage of "divination of good and bad fortune".

How can we tolerate this?

With a wave of his wand and a telescope in hand, his goal is to elevate astronomy from a "required, easy subject" to a "cutting-edge magical engineering" capable of changing the magical world!

From drawing precise star maps imbued with magic to developing powerful spells that draw upon the power of the stars;

From analyzing the probability theory behind divination to creating astrological artifacts based on constellations...

While Voldemort and his followers were still obsessed with pure-blooded people on Earth, a scholar under the stars was quietly turning the entire universe into his magical laboratory.

This is the story of a hardcore academic genius who, in a magical world, uses scientific thinking to climb the magical technology tree, and incidentally crushes everyone else in the process.

The rating is low at the start, don't be scared away! I solemnly swear, this is a divine herb, not poison. Transmigrating to the HP world, Luke awakens the Magic Chef System, harvesting emotional points with delicious food to exchange for rewards.

As for learning magic at Hogwarts? Sorry, you can freely exchange for spell learning speed, potion-making skills, and alchemy experience. With a system, you can really do whatever you want.

Thus, the teachers and students of Hogwarts witnessed the terrifyingly strong yet seemingly unorthodox freshman Luke.

[Congratulations, host! Your Magic Hawthorn Candy Balls have successfully garnered 1000 positive emotion points, easily earning you the Beginner Transformation talent!]

Minerva McGonagall: Didn't the principal say you weren't good at it? You learned it in the time it takes me to twist my hip?

[Congratulations, host! Your magically spicy hot pot has successfully garnered 10,000 positive emotion points, instantly transforming you into a fire god in half an hour!]

Dumbledore: To be able to perform such a move with just a slight glance at my notes... perhaps he's more suited to it than Harry...

[Congratulations, host! Your Magic Lamb Skewers and Lamb Kidneys have successfully garnered 10,000 negative emotion points. You can claim the Dark Lord's Three-Piece Set without any side effects.]

Voldemort: You're just a little wizard from Badger Hill, why aren't you doing your job properly and learning dark magic? Don't I have any dignity?

...

When everyone's stomachs took the shape of Luke's, his magical talent and strength skyrocketed. A chef? Call him the God of Cookery!

The Death Eater was stunned: Oh my god! Run!

He is the real demon king!

Who has ever seen someone catch Avada Kedavra with a spatula?

Laudgreen displayed his extraordinary magical talent as soon as he entered Hogwarts.

Potions is easy to learn, but most of the finished products can only be drunk by animals. Snape regarded him as a fool who tarnished the great potions.

Transfiguration can easily turn inanimate objects into living things with their own thoughts, but it is powerless to do the opposite, which greatly puzzled Dumbledore.

In the study of spells, the spells cast by Lord always have some strange effects.

He only had no problems with Potions and Magical Creatures, and the magical creatures even regarded him as a child of nature.

Everyone praised him, saying he would become the next Newt Scamander, but he stuck to his profession.

Laudgreen: Although I am a master of Transfiguration, my spells are incredibly creative, and the magical creatures trust me, I am actually a botanist.

Why did I transmigrate into this guy's body?!

Snap snap snap~

The angry boy raised his hands and slapped himself until his head looked like a pig's.

"Excellent work, reward me!"

A voice echoed in his mind, interrupting the pig-headed boy's chaotic thoughts.

You have received a reward of 666 Galleons from the system.

And in that Diagon Alley, a boy grasped his first magic wand...

"Wow! This thing is interesting!"

[You have received a Wizard Duel Gift Pack as a reward from the System Master]

A casual, appreciative system master

A manual left behind by an adventurer who grilled a phoenix.

An ancient secret, its traces erased by time.

When the stone pillar that sealed history crumbled, demons symbolizing destruction emerged from hell.

In Hogwarts, the Knights of Conquest donned ferocious heavy armor and charged straight forward, their feet treading on blood and fire.

This is a not-so-serious, but still very serious, Harry Potter fanfiction.

Welcome to the world of magic!

First grade, Horatio: Headmaster, look, use this scythe of mine to hook out the soul, then lock it in this lamp and roast it with the fire.

Second grader Horatio: Principal, look at this cabbage! It can increase in value infinitely and even kill the basilisk in an instant!

Third grader Horatio: Principal, do you think this soul contract could arm the Dementors into my army of Soul Reapers?

Fourth grader Horatio: Headmaster, look, this gravity magic can pull down meteorites from outer space to strengthen Durmstrang and Beauxbatons College.

Fifth grade, Horatio: Principal, you said if I projected this mark onto the moon, everyone who saw it would be brainwashed into a believer in houttuynia cordata, and the houttuynia cordata I planted in the Forbidden Forest would sell like hotcakes.

Sixth grader Horatio: Headmaster, look! The tree that grows from this seed can convert cosmic energy into magical seeds. Then all of humanity can become wizards, mastering both technology and magic. Conquering the stars will be just around the corner!

Seventh grader Horatio: Principal, look...

Dumbledore: "Enough talk. Take out your wand. It's either you or me today."

The blue nine-magatama Rinnegan, with a fat, silly and cute duck god standing next to it.

Until one day, Voldemort and his army of Death Eaters surrounded Hogwarts Castle.

Our little Sith was guarding the castle gate alone.

"Tom Riddle, today you will feel what true despair is!"

"Psyduck, Freeze Ray!"

Poor Bellatrix was frozen into an ice sculpture.

"Senjutsu, Wood Release, True Thousand Hands!"

"Susanoo!"

Chen Hao stood on top of a hundred-meter-high Susanoo Buddha, looking down at the shivering Death Eaters below.

"Are you ready?"

Inside the castle.

Luna: "Sith, you're so handsome!"

Hermione: "Harry, are you sure your cousin is human?"

Ron: "Harry, a new generation of Dark Lord is born, although this guy is a bit flat!"

[Single female protagonist Hermione (yandere version), invincible, daily, only the Harry Potter world, a lot of personal settings.]

[I'm really a yandere, I don't like it if you mistakenly enter. I really can't write a description, so let's leave it at that.]

Humans are the protagonists of this world. They will never know their own potential, let alone what kind of existence they can give birth to.

When humans created the word fear, fear took on a physical form...

Travel through the world of Harry Potter and obtain the [Positive Energy Explosion Attribute System].

As long as you do positive things, the relevant people may drop attributes.

"I picked up 1000 Occlumency experience points, and my Occlumency skill level reached max. I got the achievement: Spell Mastery!"

"I picked up 500 points of Potions experience, and my Potions skill level was upgraded to level 5. I got the achievement: Potions Master!"

"I picked up 1000 points of physical experience, and my physical fitness increased to level 7. I got the achievement: Tear a dragon apart with my bare hands!"

...

Snape: "Are you an expert in potions? You should be the one to take the potions class from now on!"

Dumbledore: "You can master all spells at once, and you are so positive! You are the hope of the wizarding world!"

Voldemort: "We are all wizards. What do you mean by tearing the earth apart with your bare hands? Also, how come you are more proficient in dark magic than I am?"

Looking at the various black magic spells at the maximum level on his panel, Lynch was speechless.

Do positive things, why is the attribute explosion rate of black magic so high?

He looked at the admiring eyes of the people in the magic world:

"Although I'm very proficient in the dark arts, that doesn't prevent me from being the most positive wizard in the world. No one should object, right?"
