The young biologist Levitra accidentally traveled to the world of Harry Potter and came to the era of Grindelwald, and his body age turned back to eleven years old.

"Ding! The merit system is being bound to the host. You only need to do good deeds to redeem rewards with merit points! In addition, as long as the host finally achieves the Dark Lord achievement, he can become a god on the spot."

Levitra:? ?

A few years later...

Dumbledore: He is a great man. In this era, not many people are willing to sacrifice their own interests to help others.

Grindelwald: Nonsense! Although this guy is young, he will do anything to achieve his goals. He is obviously one of my generation!

Newt: That young man looks more ferocious than a violent fire dragon, but... why is Qilin so close to him?

Tom: Who asked you to be the Dark Lord like this? Sometimes I want to call you a saint!

Levitra: Saint? No nose, you curse too dirty!

Traveling through the world of Harry Potter, Lucien awakened the loan magic system. With a flick of his hand, he could advance his rewards!

Of course, debts still have to be repaid.

So, the students at Hogwarts got to know a new student who was not only better than you, but also more competitive than you.

[Congratulations to the host for obtaining "Loki's Faceless", please repay the loan: Perfectly master the art of transformation]

Dumbledore: "With talent and hard work, could it be that Lucien is the future of the wizarding world? But the prophecy..."

[Congratulations to the host for obtaining the "Dark Magic Encyclopedia". Please repay the loan: Voldemort's head]

Voldemort: "What do you mean you owe a debt and need to borrow my head?"

[Congratulations to the host for obtaining the "Resurrection Potion Formula". Please repay the loan: create fifty new potions.]

Snape: "Lucian has developed the formula for the resurrection potion? Lily... tell Dumbledore I'm resigning as Potions Professor? Go find Lucian!"

…

Lucien put his hands behind his back and said, "I didn't expect to be this good. I just took out too many loans."

"Don't put all your hopes in the 'savior', let me carry the burden!" "Believe me, there is nothing to fear from Voldemort, he was never our true enemy!" Ethan Vincent, winner of the 2008 World War II Award

Dumbledore: "Mr. White is the most gifted student I've ever seen, but unfortunately he just doesn't like to study..."

Voldemort: "Why? He learned the dark magic I painstakingly studied just by yawning?!"

Charlie lay on the sofa and sighed helplessly, "I don't want to either, but the system is giving me too much!"

He came to the magic world with the spark of arcane civilization, vowing to rewrite the fate that was destined to be tragic.

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!

Kevin traveled to the world of Harry Potter and grew up in an orphanage without ever coming into contact with magic. It was not until he was 11 years old that he finally received the admission letter to Hogwarts.

Reborn, he just wants to enjoy this magical journey, but as time goes by, he can't help but get caught up in it...

"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.

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.
