Edward traveled through time again and came to a mysterious world.

From then on, there was a stranger here who could travel between the two worlds regularly.

So, what will he bring to both worlds?

ps1: This book is a traditional fan work and will not completely abandon the original characters to tell the story. The heroine is Miss Justice, and she may join the Queen later on.

ps2: The path of the protagonist of this book is semi-original. He takes the path of [Apprentice] in the early stage and starts to change in the middle stage.

ps3: The protagonist is basically invincible in the same level, but he can't kill high-sequence enemies.

The tallest tower in Nurmengard

This is a forbidden area for wizards throughout Austria and even the world.

At that moment, the cry of a baby with sunset-colored hair shattered the long-lost peace!

Grindelwald: Her bright smile will always inspire those who walk with her and light the way for the rest of my life.

A certain White Demon King: This little girl's childlike innocence and vitality are like fireworks in the night sky.

A diary entry: He is my salvation, my hope, the person who changed my life.

There's a legend circulating around Hogwarts: Miss Lacus's first cry gave birth to the Dementors; Miss Lacus's first nightmare gave birth to the Obscurus; Miss Lacus's first fear gave birth to the Boggart; Miss Lacus's first laugh gave birth to Peeves; and Miss Lacus's light side became Voldemort! "Hogwarts, that's all a lie!" Miss Lacus protests. "Your light has no dark, heavy secrets, only light and bright!"

(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——

Humans are the protagonists of this world. They will never know their own potential, let alone what kind of existence they can give birth to.

When humans created the word fear, fear took on a physical form...

The following worlds have been confirmed: Baldur's Gate, The Witcher, Cyberpunk 2077, and Hogwarts.

"Don't go out after dark. There have been a lot of fake people showing up in the city lately," my brother—the infamous Rainy Night Butcher—warned with a serious expression.

"Your brother's right," Mom—the Original Fake Person—nodded with concern.

"Bro, can you pick me up after school? I’m a little scared." My little sister blinked at him. But in truth, she was an A-Rank Hero from the Hero Association.

"Your brother’s just recovered from a serious illness. Let him rest at home, I’ll go get you." My older sister, the Captain of the Night Watch from the Special Operations Bureau, took on the task.

Qiao Qingshan, who knew all his family’s identities, said nothing—he just kept fiddling with his phone.

And so, my peaceful daily life began...

"Due to the recent outbreak of fake person incidents, we interrupt this program to bring you an emergency notice from the Special Operations Bureau."

1. Fake people often take over the bodies of those who’ve just recovered from serious illnesses by using a technique called 'soul possession.' If someone who has just recovered begins acting strangely, pay close attention.

2. There are no such things as 'transmigrators' in this world. Anyone claiming to be a 'transmigrator' can be immediately classified as a fake person.

3. Fake people who claim to be 'transmigrators' are considered extremely dangerous. Do not trust any information they provide, including but not limited to emotional expressions, identity claims, or cries for help.

Faced with the suspicious looks from his family, Qiao Qingshan could only sigh.

Alright then... so much for my peaceful daily life.

(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...

In his previous life, Harry defeated Voldemort, protected the wizarding world, protected Hogwarts, and became a great wizard like Dumbledore. After a long time, when he was about to leave, he thought of the blond boy. What will happen to them after their rebirth? Harry's life will also change, and his relationship with Professor Snape will also be unusual.

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.
