"Professor Dumbledore, have you ever seen Hogwarts at four in the morning?" Russell said calmly. "From midnight to six o'clock, get six hours of sleep." "From six to eight o'clock, sweat it out in the Forbidden Forest, including but not limited to wrestling with trolls, practicing riding on unicorns, dodging centaurs' arrows, and so on." "From eight to six, be ready for a full day of study." "From six to ten, study late into the night in the library." "From ten to twelve, practice dueling skills in the Room of Requirement." This is the simple yet fulfilling day of Russell Fishthorne, the King of the Curriculum at Hogwarts.

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.

But some vengeance still needs to be avenged.

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.

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.

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."

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."

Joel Hemis always thought of himself as an ordinary druid. Until he was eleven, when he received a letter delivered by an owl—and from that moment on, he became a proud little magical owl. ...That school year, the Forbidden Forest welcomed a Patronus. By the time all the teachers and students of Hogwarts realized what was happening, they were already surrounded by the Forbidden Forest!
