Two armies faced off, dragons danced wildly. This was a war between the living and the dead, a contest of life and death, a divine duel between the Cold God and the Red God, a song of ice and fire. Harry Potter, rising above the crowd, arrived at the battlefront: "Ten years of bitter fighting have finally brought us to this day." "Brave men bid farewell to their loved ones, raging with rage as they spill the blood of their enemies... and we, our names will live forever!" "Our fame will inspire future generations of heroes!" With these words, Harry, filled with rage, drew his flaming sword, turned, and roared: "Night King, stand forth!!!"... After years of battle in the world of A Song of Ice and Fire, Harry returned to his loyal Britain, armed with the King Training System. Hagrid brought a message: In the Scottish Highlands, our home, at the world's greatest school of magic, Hogwarts, your name has already been written in the acceptance book. "So I'm a wizard..."

(Otome + multiple male protagonists + sweet love + separate endings + parent generation + child generation) Lina, a male health expert, traveled through time to the magical world of Harry Potter and became Selina Lestrange, a therapist at St. Mungo's. She was also a crazy fan of Sirius Black. She took advantage of her position to go to Azkaban every day, but it was hard for her to "deepen her roots" in a field she was not good at.

See how she shakes off the label of "star chaser" and "rebuilds her reputation" at St. Mungo's! And wins everyone's love (mistake)!

Sirius: That woman has changed! How come she's still... pretty?

Snape: I don't have that disease, thank you!

Lucius: I heard that you can help me give birth to a daughter?

Bill: Thank you for your care every time

Barty Jr.: You saved me, my life is yours...

Please look forward to more male protagonists——

(Sirius chases his wife to the crematorium ➕ all members survive ➕ private settings like mountains, focusing on otome literature for a hundred years, the official pairing may be broken, if you don't like it, please don't enter)

(The Big Bang Theory×HP. Warning to otome fans, especially those with a special madness ⚠️) Penny suddenly discovered that her bed had become a passage to another world. Every night it was connected to the beds of people from other worlds. There was always a stuffy old man who called himself "Professor" sharing her bed.

This guy had a terrible temper and a sharp tongue, and he always said things to her that she couldn't understand. And then, after an accident, she was able to see him? What's more, she could enter and exit his world?

Snape's perspective: At first he thought it was the Death Eaters who were causing trouble, but later he found out it was a curse and a calamity for him. He was the only one who could sense the damn stupid woman. No matter how many times he changed beds in the room, he could still feel her body approaching like a gorilla when he slept at night, and magic was ineffective on her. Later he could see her, and she was even more shameless to threaten him with this, the woman who only knew how to drink and eat, and blackmailed him with "beauty" magic.

He was a fool with only a pretty face, so he wouldn't fall for her trick. But as time went by, when everyone could see her, Snape always felt like he had lost something...

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.
