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.

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

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!"

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!

"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!"

When a science PhD travels to Hogwarts, he discovers that magic is just another form of energy—as long as there is a theory, it can be quantified, copied, and enhanced!

From analyzing the structure of wands to developing magic circuits and energy arrays, he ushered the wizarding world into the "era of technological magic."

Voldemort was sent to the research institute by him, and Dumbledore asked him to give a public lecture on "Magical Physics".

However, this was just the beginning—when he broke through the dimensional barrier, new worlds began to emerge:

In Middle-earth of The Lord of the Rings, he single-handedly suppressed Sauron;

On the continent of The Witcher, he combines magic and runes through alchemy;

In the Marvel Cinematic Universe, he even got Tony Stark to come and get inspiration from him;

After Harry Potter, he will eventually become the supreme god of magic in all the heavens and the myriad worlds!

It took Samael 11 years of traveling back and forth to realize that he had come to the world of Harry Potter and had become a wandering descendant of the Gaunt family.

What kind of sparks will be produced when Parseltongue meets Anaconda?

What effect will occur when werewolf venom is combined with the blood curse?

What changes will happen when Orochimaru meets the Green Snake with Three Flowers?

Samael Gaunt, a wizard seeking fame and power.

Harry Potter: He was my best friend.

Dumbledore: He is a true Slytherin.

Snape: He might be the third Dark Lord.

Hagrid: We have the same hobbies.

The incomplete fragment of the artifact carried a soul to the magical world we imagine, albeit a little too early. Voldemort was still Tom Riddle, Snape's mother hadn't been born yet, and the original Dark Lord was still striving for the greater good.

The male protagonist has no CP in the main text, but there is ambiguity in the early stage. Support ggad, Sili

"You want to take over the wizarding world?" Lucius Malfoy looked interested.

"No," Lin Zhen smiled. The sunlight shone on him, making him look like a holy angel. "Controlling the world is too tiring. I just want to change the world."

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.

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.

"Albus Dumbledore made two great mistakes in his life: one was Tom Riddle, and the other was Jim Lynch." Jim Lynch, the "Mist Hangman," a forbidden legend who hunted hundreds of dark wizards, was locked in the Forbidden Forest by Dumbledore himself. When the savior Harry enrolled in school, he tore open his cage and returned to the wizarding world as a professor. Dumbledore regarded him as a hidden danger, and the Ministry of Magic became his chess game, with death walking with him. When the sky of Hogwarts was set on fire, Lynch stepped out of the fire and smiled elegantly at Voldemort: "Hello, Tom, did you miss me?"
