After graduating, Amosta Bryan concealed his identity and hid in the underground world of the British wizarding world.

He wandered on the edge of light and darkness, danced at the junction of life and death, and used the rewards of entrusted tasks to support his own path of magic traceability and return the grace of the orphanage for his upbringing.

Until one day, he was brought back to Hogwarts by a mission with ulterior motives, and since then, the established destiny has once again headed home!

Twyle, the most outstanding graduate in Durmstrang's history, came to Hogwarts.

"One day, Muggles will be able to use science to observe magic, to see through our magic, and to construct a mathematical model for every spell.

"What will the wizards do when that day comes?"

"Being caged like a rare animal?"

"still……"

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

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.

He traveled to the Harry Potter world with a simplified system. He thought that with the system, he would become the richest man in the world. However, an acceptance letter sent by an owl changed his plan. It turned out that he was not in the city but in the magical world...

I took the letter and looked at the familiar logo on the cover, then looked at the time on the calendar hanging on the wall, and fell into deep thought...

Even though he hated Nanny Wen in his previous life and still hates her now, he doesn't hate others being his nanny!

It’s just that at this point in time...

Well, I can’t rely on the care of the three protagonists anymore, so I can only rely on their parents.

But I didn't expect that I didn't get the thigh, but I became the thickest thigh...

A few years after graduating from Hogwarts, Claire returned to Hogwarts in a different identity. This time, he came back with his own purpose! It was because of this return that he discovered the different secrets of the professors at Hogwarts! Headmaster Dumbledore, the greatest wizard of our time who talks nonsense! Professor Snape, the head of Slytherin House who loves and focuses on ethical blockbusters! Professor Hagrid, the Hogwarts key keeper, the Forbidden Forest warden, and the future Professor Hagrid, the head of Hogwarts Care of Magical Creatures, who is keen on studying the genetic inheritance of magical creatures! ... ...The true face of Hogwarts slowly revealed itself to him! !

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?"
