[Single female lead, Hibiscus, a genius protagonist. The story will try to follow Rowling's original character traits as closely as possible, though some elements may be added by the author.]

Having been reborn into the world of Harry Potter, Raven only wants to live a happy and joyful life with his family and friends.

So Hogwarts gained a little badger who always acted on his whims.

Harry: Where's Raven? I want to see if he'd be willing to help.

Ron: He seems to have gone fishing in the Black Lake.

Harry: But I just checked the Black Lake, and it's not there!

Ron: Maybe he went to have hot pot with Hagrid? He always says that having a fish hot pot after swimming is very comforting.

......

Dumbledore: Raven, you should continue to create a few more spells so that you have a very good chance of getting a Merlin First Class before your fifth year.

Raven: But Professor, I don't want to continue. I've become more interested in alchemy and fishing lately.

Dumbledore: Your interests are very varied.

Raven: Yes, but I feel like fishing will be a long-term hobby of mine. Those damn fish just won't bite. I think I need to learn some new techniques to deal with them.

......

Grindelwald: You possess the immense talent of Raven, you...

Raven: Sorry, Mr. Grindelwald, I'm not really interested in the greater good.

Grindelwald: But war between wizards and Muggles is inevitable.

Raven: Let the people who should be worried about this worry about it. I'll bend over if the sky falls.

Grindelwald: ......

......

My dear grandpa is actually a werewolf, the truth behind the Philosopher's Stone, and the back-up man behind the four founders.

None of this prevents Loren from being a bastard, having fun with Seamus, exchanging experiences with the twins, and explaining the weirdness of Quidditch...

This is a story about hanging out at Hogwarts.

Loren: Look at that cat above, it looks so easy to touch.

Hermione: Heartbeat, in short, it is heartbeat.

(PS: The three little ones are the same age, they don’t follow the main line of the original work, they don’t have a system, and they try their best not to be OOC.)

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.

"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!"

Ike Strider, a top student at Hogwarts, a stubborn library dweller, and a stowaway in the restricted area.

While Hermione and her two useless men were making trouble in the school, Ike focused on learning and studying magic.

Although under the influence of an unknown existence, he was always involved in various troubles.

But no matter what, he could not change his attitude towards magic.

After all, magic

was his only hope...

[System + Lighthearted + Humorous + Hogwarts Fanfiction + Fun]

In the dilapidated hut of the London orphanage, Professor Snape's face was so somber it seemed to drip water.

He never expected that a Muggle orphan's first words upon receiving an invitation from Hogwarts would be: "Is the tuition expensive? Can I take out several loans to invest?" [Resentment level +19!]

Signas, a transmigrator, awakens a system that allows him to absorb the "resentment" of others. Not only can he win incredible items through lotteries, but he can also directly enhance his magical skills! From magic immunity potions to instantly mastering profound spells, he discovers that Hogwarts is practically his personal "resentment ATM"!

Signas solemnly promised: I never provoke trouble, but if someone comes to me with their grievances, I will never hesitate to take action.

[You've successfully angered Snape and won the rare item 'Calming Potion' in the lucky draw!]

[You successfully tricked Professor Quirrell, gaining a large number of skill points and Levitation Charm LV10!]

You successfully pulled down Malfoy's pants...

You have successfully enraged Voldemort...

...

Hermione: Signas, that's incredibly disrespectful to the professor!

Ron: Hey buddy, you made Malfoy cry again!

Harry: Signas, how did you do that?

Voldemort: Damn it! Mudblood, what have you done...?

Signas: Actually, I really didn't mean to make you guys angry!

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.

Leonard, an earthling, travels to Hogwarts and awakens the powers of the Seven Gods of Teyvat (wind/rock/thunder/grass/water/fire/ice), but he needs to gradually unlock them through the sacred relics of Hogwarts' underground leylines - the statue of the God of Wind in the Astronomy Tower, the statue of the King of Rock in the Chamber of Secrets, the Fountain of Wisdom in the Forbidden Forest... Each sacred relic contains a thousand-year contract between the ancient elemental wizards and Hogwarts.

As Hermione Granger's distant cousin, his wandless levitation and rock-lance combat astonished the wizarding world. Hermione, with her photographic memory, translated these powers into learnable "elemental spells," becoming his sole theoretical partner. From using wind to generate bay leaves in Potions class, to using a rock shield to block the basilisk's petrifying gaze in the Chamber of Secrets, to using lightning to split the Dementor's black mist in Azkaban, the two redefine the possibilities of magic through the complementary "wisdom and power" of the original novels.

As the power of the Seven Gods is gradually released, Leonard discovers that Voldemort's Horcrux is actually a "crystallization of abyssal energy", which can only be destroyed by the corresponding power of God's Eye - the Rock King's Spear shatters the golden cup, Wuxiang cuts off the diary with a single blow, and the Echo of Green purifies the poisonous fog... and Hermione pieces together a bigger truth from the family genealogy and "A History of Magic": the gargoyles and leyline obelisks of Hogwarts, and even the entire magical world, are all in line with the elemental laws of Teyvat.

When the final battle came, the shadows of the Seven Gods appeared over Hogwarts. The Wind God swept away the Death Eaters, the Rock God held up the city shield, and the Thunder God cut off the dark magic... Leonard and Hermione stood in the center of the seven-pointed star, weaving the fate of the two worlds with the resonance of elements - it turned out that as early as a thousand years ago, the authority of the Seven Gods had laid the foundation for the protection of the world.

Mike looked at the white marble tomb in front of him and stroked the elder wand in his hand. After a while, Mike raised his head expressionlessly and said, "Let's begin!" A group of wizards stood neatly behind Mike. They were all wearing white robes. They all looked excited when they heard Mike's order. He began to release phantom and disappeared into twisted figures. Mike was left standing alone in front of Dumbledore's grave, stroking the elder wand in his hand. "You know, how can a mudblood like me succeed without doing some evil things? All for the greater good."
