In his previous life, Harry defeated Voldemort, protected the wizarding world, protected Hogwarts, and became a great wizard like Dumbledore. After a long time, when he was about to leave, he thought of the blond boy. What will happen to them after their rebirth? Harry's life will also change, and his relationship with Professor Snape will also be unusual.

[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.

As a time traveler from the Harry Potter universe, Vilan Costa always considered himself lucky. This was because in the timeline he traveled to, the infamous Voldemort had just reached the pinnacle of his power when he was assassinated by an unknown powerful wizard. He and Harry enrolled at Hogwarts at the same time, studying together in Gryffindor House. Harry lacked the lightning-shaped scar and the reputation of a savior, but he had both parents and a happy family. Vilan spent his first three years at Hogwarts uneventfully, until the summer vacation of his third year, when everything changed. His right eye developed a problem. After several days of unsuccessful treatment, it gained a unique ability—in short, it could accurately detect tiny marks on objects...

He traveled to the world of Harry Potter and became Ron Weasley, awakening to an extraordinary level of enlightenment, which brought a bit of a shock to the magical world.

"Your comprehension is extraordinary. By visualizing the starry sky, you learned the Star Sword Technique, and with one strike, you can freeze fourteen continents."

"Your comprehension is extraordinary. By breathing while asleep, you've learned the Great Dream Breathing Technique. You can practice it while you sleep."

"You have an incredible comprehension. By observing, you learned the Animagus transformation and mastered the Seventy-Two Earthly Demon Transformations."

"Your comprehension is extraordinary. Through practicing the flying broomstick, you can fly with a sword and take heads from thousands of miles away."

Ron single-handedly killed the dragon, and Harry Potter said: "And my friend, you are the real savior."

Seeing Ron master all the spells, Hermione Granger said: "Genius is just the starting point for you."

Ron destroyed the city and split the sky with one sword. Dumbledore said: "My boy, you have shown me what real magic is."

Ron imprisoned Voldemort in the Horcrux, and Voldemort said: "I wish I had never been born."

Ron chuckled: "When I'm not practicing, you see me as the bright moon in the sky. When I'm practicing, you see me as a mayfly seeing the world!"

What should I do if [Transformation] + [Marvel] + [HP]

is in the wrong world?

Hermione dressed as an HP world, but appeared in Marvel.

A mysterious magic book that makes Hermione jump back and forth in the worlds of Marvel and Harry Potter.

……

Tony Stark: It's time to study the Anti-Wizard Warframe.

Hermione: Are you talking about your ragged mantling that was torn down by whom?

Hulk: Roar!!

Hermione: Shut up and be careful I remove your pants...... Except for your weapons!

Ancient One: There are no mages on the timeline......

Hermione: Again, I'm a wizard!

Nick Fury: Where exactly are you from?

Hermione raised an eyebrow: I, Hermione, from Hogwarts!

[The protagonist's belly is black, the main world HP and the Marvel Cinematic Universe, there will be other Marvel worlds in the future, but they will not be fused]

Young An Ang travels to the magical world and, after many hardships, becomes the Sorcerer Supreme. Just as he is about to take control of Kamar-Taj, he suddenly receives an owl from Hogwarts and awakens a heaven-defying system. As long as he completes the heaven-defying tasks, he will receive unexpected artifact rewards.

An Ang smiled. It was time to give the magical world a little shock from the Sorcerer Supreme!

Why did the Savior change from a man to a woman? Why did Professor Snape cry during class?

Why does Professor Quirrell keep getting elbowed in the back of the head by giants?

Why is Professor McGonagall obsessed with mysterious plants? What kind of bizarre quest is "Educating Hermione"?

Why did all the Death Eaters suddenly start clamoring to quit overnight?

How will this terrible darkness, which threatens multiple magical worlds, end?

It all started on the day that the Venerable Master An Ang entered the academy.

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?

After traveling through the Harry Potter world for seventeen years, Whitefall, who could only use dark magic, was expelled from Hogwarts and became a Death Eater. He was later imprisoned in Azkaban for helping Voldemort.

With no other options left, he took out his wand and was about to commit suicide.

As he was about to die, he heard a golden light explode in his head.

[Ding, your Infinite Forbidden Spell System has been bound.]

No, I was already in Azkaban, and Goldfinger only came?

When he woke up again, he had returned to the scene seven years ago.

At that time, he had not yet entered Hogwarts and was surviving in the cracks of an orphanage.

With the help of the system, Bai Yun uses power far beyond black magic to reach the pinnacle of magic.

If he were to live his life over again, he would make the entire magical world submit to him!

"Auror? What does your arrest of dark wizards have to do with me, the Forbidden Spells Master?"

"Death Eaters? Do you think a mere Voldemort is worthy of my submission?"

"Defense Against the Dark Arts? Sorry, I was instantly killed by a forbidden spell!"

In this life, Bai Yun officially opens a new era of the magical world with his memory and golden finger!

Harry: It seems my classmates are more dangerous than Voldemort?

Dumbledore: Our house has opened Azkaban?

Voldemort: You are using my words!

[Some settings have been added to the magic system, which may affect the settings of the original work]

Arthur Blake.

(The only legitimate heir of the Black family and an important partner of the "loyal and brave" Malfoy family.)

Arthur did not practice or use the Dark Arts like most of the Black family.

On the contrary, Arthur learned a kind of magic that was rarely mentioned in the entire Harry Potter world, magic related to lightning.

This was the ability of Thunder Magic, possessed by a max-level character he used in the game he played before crossing over.

Originally, he wanted to wait until his thunder technique was perfected, then appear out of nowhere and shout to Voldemort, "Use thunder to shatter the darkness!!!"

However, Voldemort, who had lost his brain, not only wanted to steal the Philosopher's Stone, but also wanted to control him.

Arthur thus encountered his first crisis that threatened his life.

However, Arthur, who turned a disaster into a blessing, found another way besides thunder - soul magic.

------

Voldemort had marked himself with the most powerful enemy he had ever faced, once again fulfilling the prophecy about the savior without his knowledge.

At the moment of his death, he felt immense regret in his heart.

It was then that he remembered what the famous five-star-rated General MacArthur once said: "At the beginning, I thought I knew everything and could control everything; but later I found that the fact was that I knew nothing."
