Dumbledore quickly grabbed Orion who was about to cast a spell.

He wiped the sweat from his forehead and said, "Alas~ It's not appropriate to do this in broad daylight. Fiendfyre is a powerful dark magic and can't be used carelessly!"

Orion nodded and said, "I understand, Principal. We can let him go if we carry some people on our backs, right?"

[Single Female Lead], [Le Ziwen]

A time traveler who was sent into another world by a dump truck, with an unreliable grocery store system.

While eating barbecue and humming a song in his small home in the valley, the old man with a crooked nose suddenly put a wizard hat on him and said that he wanted to start school early.

Evan has time-traveled once again.

His first time traveling was from Earth to the D&D world, where he went through trials and tribulations and became a sorcerer of the Universal School.

However, a fierce battle ended his second life.

When Evan opened his eyes again, he was surprised to find that he had once again traveled to a magical world that was both familiar and strange.

An owl flapped its wings and flew swiftly, delivering his Hogwarts acceptance letter, but the timeline he arrived in was 1971.

In 1971, a turbulent era, the Demon King was stirring, the Phoenix perched high in the castle, and the towers of Nurmengard remained tightly shut.

And those future heroes—Lupin, Sirius, James, Lily, Snape… at this moment, they are just innocent teenagers, unknowingly walking into the vortex of fate.

This is a glorious era, though not detailed in the original work, it is equally magnificent and filled with brilliant stars.

However, for Evan at this moment, the first thing he needs to solve is how to restore his spellcasting ability in this world without a magic network and with scarce magic power.

Or perhaps, he could go even further, relying on more advanced magical research concepts, gathering a group of intelligent and powerful companions, and launching a magical revolution that would change the entire magical world.

In any case, the times are waiting for Evan's actions.

-----------------

The timeline is set in 1971, in the same year as Sirius Black, Lupin, and Snape. The protagonist has mastered the spell system of D&D, has no system, breaks up the original pairings, is slow-paced, not mindless, and will seriously consider the plot.

[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.

Many years later, Harry Potter, who was hailed as the greatest white wizard of this century after Dumbledore, was interviewed by a reporter.

"Mr. Potter, is the person you respect most Headmaster Dumbledore?"

Harry shook his head.

"Is that Professor Snape?"

Harry still shook his head and said softly, "From beginning to end, there is only one person I respect, and that is my teacher - Al Yaxley."

The Hogwarts High Inquisitor's Order prohibits any professor from providing students with violent, morbid, or information that cannot be explained by magic. Any professor is prohibited from teaching students how to commit crimes in disguise by setting up crime-solving and decryption sessions in class. The above regulations are in accordance with Article 34 of the Education Order. Signed: High Inquisitor Dolores Jane Umbridge... "Good heavens, Hermione. I think we should go tell Professor Holmes that his entire course has been defined as illegal by the Ministry of Magic..." "Yes, Ron. But you probably can't find him now, because he just took Harry to the Chamber of Secrets." "The Chamber of Secrets? What is he doing there?" "Little things like stabbing himself with the fangs of basilisk and wipping the basilisk's corpse!"

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!

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!"

As the grandson of Gellert Grindelwald, Claude was treated as the third generation of the Dark Lord from the moment he began attending Durmstrang. Later, forced to defend himself, he caused a disturbance and was expelled. After transferring to Hogwarts, he enjoyed a pleasant life, but later discovered that the wizarding world was not as simple as he had imagined: traveling across millennia, applying magical rules, possessing artifacts, and even discovering the existence of gods. All of this was due to a wish granted by a god.
