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.

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."

[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.

In 1991, Harry Potter, who was looking forward to campus life, stood on the platform of the Hogwarts Express, accompanied by his parents, godfather, Uncle Remus and a snow-white owl, and hugged and said goodbye to them one by one. The wind blew his bangs aside, revealing his smooth forehead above his green almond-shaped eyes. He just felt that he was the happiest little wizard in the world. The last person to say goodbye to him was his godfather, Sirius Black. "Harry, remember, have fun!" Black squatted down, his grey eyes sparkling, "If anything happens, you know, just look for Uncle Regulus—" This is a story about a game geek who plays "Assassin's Creed" and travels through time to the story of Regulus Black, a relative of Harry Potter. Regulus is responsible for hard work, and others are responsible for happiness! Protagonist: All..

Others learn magic for great benefits, but Noah learns magic simply to have fun.

Thus, the aged Nicolas Flamel became a bald, muscular boxing champion, Voldemort regressed to a five-year-old child, and the entire school was forced to go clubbing on their first day of school—from then on, the art style completely collapsed! —When an alchemist's pranks become his strongest weapon, the entire magical world becomes his playground!

(No female lead + Career-focused + Pseudo-system + GGAD + Independent rise to power + Super cool personality)

Xiao Er transmigrates into the world of Harry Potter and inherits the Black family estate. Upon entering Hogwarts, he discovers that this magical world is far from simple — and his own origins are even more mysterious.

He dominates Slytherin, becomes the top student, handles Snape with ease, teases Draco, redeems Theodore, reunites GGAD (Grindelwald and Dumbledore) at the tower, establishes a magical throne, inherits the ideals of pure-blood supremacy, and breaks through a decaying world!

One legendary tale after another unfolds.

— Content Warnings —

The protagonist starts off as someone who goes from rags to riches and might get a bit arrogant, but evolves into timeless elegance.

Apart from GGAD as the canon male/male pairing, there’s no romance in the main plot. Fan extras might include other CPs (couples).

Ron is portrayed as mildly antagonistic in the early stages, but he matures later on.

The shadow cast by two generations of Dark Lords gradually dissipated.

The White Lord (crossed out), the greatest wizard of this century, fantasized about receiving woolen socks in the headmaster's office.

Ryan Wells lived a quiet and leisurely life at Hogwarts.

With some insignificant external help, he was held in deep reverence throughout the wizarding community.

"Master Ryan! Do you have any new prophecies today?" People traveled thousands of miles from all over the world to Hogwarts in the hope of receiving a prophecy.

"Senior Ryan, what should I pay attention to today?" asked the younger students who had been helped.

"Ryan, any new prophecies?" Professor Flitwick cast a levitation spell on himself and patted his favorite student's shoulder affectionately in mid-air.

"Mr. Wells, what are your thoughts on the Ministry of Magic's future work?" asked the Daily Prophet reporter...

On a frozen tundra, through the billowing steam and blinding blizzard, the shape of a colossal beast slowly emerges.

A grotesque construct seemingly cobbled together from wood and iron, devoid of any sense of beauty or design. Whether it can even move is a mystery—it’s a wonder it holds together at all.

At the front is a massive steel face locked in a twisted grin, with a red mechanical tongue lurking inside its maw.

Below, four claw-like mechanical legs—thin and bird-like—stride awkwardly through the snow, barely supporting the towering monstrosity above. Their fragility is alarming against the beast’s massive frame.

They say, deep within the fortress, a mysterious figure dwells… weaving the fate of all who live.

★★★The new book "Hogwarts' Vampire Count Professor" has been released! ! ! ★★★Notes before reading this work: [The main plot is in the HP world, with very few Marvel plots] [The timeline is during the Grindelwald era, without the three little ones] [The protagonist is a kind camp, with a non-traditional Snake House personality] [It is not an invincible flow or a routine cool story, but tends to be growth-oriented and group portrait] [The plot is in the later part of the book, and Voldemort is not the final boss] "Voldemort, I'm here to negotiate!" Sivan, wearing a cloak, held the Ring of Raggadoor in his left hand, and placed his wand on Voldemort's brow with his right hand, with a warm smile on his face.
