(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...

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.

"Things you believed in during your childhood and the stories you experienced will become irreplaceable treasures."

"I believe that language has its own unique power, and there is nothing that cannot be solved by speaking it out!" said Xiaogong.

First grade, Horatio: Headmaster, look, use this scythe of mine to hook out the soul, then lock it in this lamp and roast it with the fire.

Second grader Horatio: Principal, look at this cabbage! It can increase in value infinitely and even kill the basilisk in an instant!

Third grader Horatio: Principal, do you think this soul contract could arm the Dementors into my army of Soul Reapers?

Fourth grader Horatio: Headmaster, look, this gravity magic can pull down meteorites from outer space to strengthen Durmstrang and Beauxbatons College.

Fifth grade, Horatio: Principal, you said if I projected this mark onto the moon, everyone who saw it would be brainwashed into a believer in houttuynia cordata, and the houttuynia cordata I planted in the Forbidden Forest would sell like hotcakes.

Sixth grader Horatio: Headmaster, look! The tree that grows from this seed can convert cosmic energy into magical seeds. Then all of humanity can become wizards, mastering both technology and magic. Conquering the stars will be just around the corner!

Seventh grader Horatio: Principal, look...

Dumbledore: "Enough talk. Take out your wand. It's either you or me today."

False druids: follow the way of nature, master the magic of nature and the form of the wilderness, and gain the ability to transform into wilderness creatures and control the elements. The real druids, however, look further: the flow of planes, the birth and death of the world, the upside-down galaxy, and even the endless echoes of the multiverse, are all the pulse of nature. Nature is not just mountains, rivers, lakes and seas, but existence itself, the breath of law, and the rhythm of time. I am nature, and nature is me. The flow of all things is in the mind. Okay, no more pretending. This is a druid who traveled to the continent of Faerun, mastered the transformation into the Star-Forging Dragon King, specialized in the Society of the Stars, controlled the power of nature and the secrets of the stars, could crush planets at will, and mastered the birth and death of the universe. Notes: Druid, stars, Star-Forging Dragon King, Plane War, Multiverse

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

Words are like silk, weaving the warp and weft of stories; stories are like rivers, settling the pebbles of knowledge; knowledge is like fire, forging the stars of wisdom; and in the folds of time, the ancient light of civilization shines forth.

In 1991, Harry Potter, who was looking forward to campus life, stood on the platform of the Hogwarts Express, accompanied by his parents, godfather, Uncle Remus and a snow-white owl, and hugged and said goodbye to them one by one. The wind blew his bangs aside, revealing his smooth forehead above his green almond-shaped eyes. He just felt that he was the happiest little wizard in the world. The last person to say goodbye to him was his godfather, Sirius Black. "Harry, remember, have fun!" Black squatted down, his grey eyes sparkling, "If anything happens, you know, just look for Uncle Regulus—" This is a story about a game geek who plays "Assassin's Creed" and travels through time to the story of Regulus Black, a relative of Harry Potter. Regulus is responsible for hard work, and others are responsible for happiness! Protagonist: All..

Matthew traveled to "Harry Potter", only to find that the world was facing the invasion of various foreign evil gods:

The "Dimensional Devil" that rules purgatory, the "Eyes of the Abyss" that dominate the spirit world, the "Paradox Devourer" that occupies the void...

There is also the "Blood Lord" who stole his chance to travel through time and whose strength has undergone a qualitative change...

There are suddenly many evil cults in the world. They are the root of the old beliefs and the anchor point for the invasion of foreign gods.

Fortunately, the system has awakened an incredible wisdom!

Yes, you read that right! The system has given itself a cheat code!

And as the host...Matthew can completely skip the comprehension steps and directly obtain the results of comprehension!

What does your understanding mean to my understanding? We just have different divisions of labor.

Many years later, when many evil gods were willing to burn the world to death in order to descend upon Hogwarts:

[You have come into contact with the origin of the laws of space. Due to your extraordinary understanding, you have gained the right to manage the crystal wall of the world.]

[You watched the world that was about to fall. Due to your extraordinary understanding, you mastered the endless world destruction chain.]

You can figure out the system, and leave Hogwarts to me!

Looking at the system prompt, Matthew announced domineeringly:

Evil God, get out of my Hogwarts!

Dumbledore: Wait, your what?
