Roger traveled to the world of Harry Potter.

The game started on hellish difficulty; he became the apprentice of an old, powerful, and extremely temperamental dark wizard. Just as he was cautiously serving this unpredictable mentor, he unexpectedly discovered that the bio-computer he had developed in his previous life had also transmigrated with him!

From then on, Roger's magical training began with the three Unforgivable Curses! "Analysis of the Imperius Curse complete." "Begin observing Professor Quirrell."

Years later, when the Daily Prophet was preparing to write a legendary feature on Mr. Roger Lewis, prominent figures in the wizarding world spoke out:

Professor McGonagall (with a serious expression of amazement): "Without a doubt, Mr. Lewis is an unprecedentedly outstanding graduate in the history of Hogwarts." Dumbledore (his wisdom gleaming behind his half-moon spectacles): "I must admit that no one understood the nature of magic better than Roger. Not even the four founders of Hogwarts." Voldemort (in a complex tone): "It is well known that I made indelible contributions to Roger's magical research..."

Rita Skeeter (writing furiously with her quill pen, her eyes gleaming with gossip): "Mr. Riddle, was it the summer before Mr. Lewis enrolled?"

Voldemort (lost in memories): "Sigh...that summer, they invited me to participate in the experiment, though the method was crude...If they had said it was to develop an elixir of immortality, I could have provided tremendous assistance! I wouldn't have needed to go through the trouble of finding the Philosopher's Stone...I still deeply regret missing this opportunity to return sooner!"

I've been transported to Hawkins, the town from Stranger Things, and become Will's brother, Jonathan Byers. This America is too dangerous; horror stories unfold everywhere, and the sweet air is thick with evil. The neighboring town is Silent Hill, with a street called Oak Street, home to the Shining Hotel. I've heard there's a cabin in the woods beyond town. Legend has it that deep in the forest lies a fairytale town inhabited by vampires and young wolves, while Jason and Voldemort lurk outside. From time to time, demons from hell invade the world, aliens are always causing trouble on Independence Day, and Thanos, the head of the Space Office, is willing to snap his fingers—if you're unlucky, you'll be vaporized to dust. Luckily, I have a Dungeon Fighter Online (DNF) game system with me, allowing me to become a professional exorcist and form an exorcist alliance. I've gathered Constantine, Johnny Depp, Van Helsing, Nick Wilde, and the Ancient One. Everyone, don't fight over this monster; let me kill it! I'm super strong… If you, fellow readers, find "This Stranger Things is a Bit Cold" enjoyable, please don't forget to recommend it to your friends on QQ groups and Weibo!

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.

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?"

[Single Female Lead], [Le Ziwen]

A time traveler who was sent into another world by a dump truck, with an unreliable grocery store system.

While eating barbecue and humming a song in his small home in the valley, the old man with a crooked nose suddenly put a wizard hat on him and said that he wanted to start school early.

(Otome + gender change + group favorite + parent-generation + multiple male protagonists + multiple endings)

What? Others who traveled through time are the Dark Lord's daughter, Harry Potter's sister, or at least a divine beast with its own system, right? Good heavens, but when I come to this place, I become the hated Peter Pettigrew?

The good news is she's still a girl, but the bad news is she has to keep her vest covered at all times when living in the men's dorm. Why is Sirius looking at me with increasingly ambiguous eyes? What? Lupin, you want to talk to me alone? Snape, aren't you madly in love with Lily Evans? And... Newt? Who are you? I don't remember your name in the book.

Watch how Alayya turns the tide and transforms from a disliked little mouse into a popular heroine!

(Note: This article involves the gender reassignment of Peter Pettigrew. Those who are incompetent should leave immediately. You are also welcome to read my other articles.)

Every time you travel through a new world, you become a strange character or even a non-character.

Talking Tom, Knight, Witch, Slime, Snow King...

Ding Hai was also forced to start a wandering life in the heavens and all realms.

When he turned into Tom Cat, he received an invitation letter to Hogwarts School.

Then, the adventure of the fun people began...

Become Harry's cousin, the original author's designated Muggle.

Brother Xun has a good saying: "Merlin closes a door for you and opens a window for you."

After getting a weird mage system... Merlin opened the skylight over Dudley's head... well, maybe Merlin lifted the roof off Dudley's house.

Dudley Dursley: "Listen, I'm not what you think, I'm a spellcaster!"

Under the moonlight, Dudley twisted his waist and put on a strange posture, and a BGM sounded behind him: "Okay, I have a showdown. I admit that wizards have limits, so I don't want to be a wizard anymore! Potter!"

"System, if you do this again, I will learn the seventy-two changes and become a Super Saiyan."

This book is also known as "The God of Physics", "Anything but Magic", "Actually I Can Magic", "I'm Really Not Harry Merlin".

"Come with me."

"I'll be your teacher before you enter Hogwarts, introducing you to the vibrant wizarding world and all sorts of wizards."

"I'll teach you everything I know: potions, spells, transfiguration, even the Dark Arts."

"And if one day you grow up to be a truly great savior, then point your wand at me."

"Use all the methods I've taught you, use all you have, and kill me!"

"Do you have the guts?"

"Lily Evans and James Potter's son—"

"Harry Pott!"

In a narrow alley drenched in rain,

Severus Snape, with smooth, fresh, non-greasy black hair, holding a black umbrella, reached out his hand to the nine-year-old savior of the wizarding world, who sat on the ground, his face filled with fear and bewilderment.

On a sunny afternoon, Kyle finally received the admission notice he had been longing for, and came to Hogwarts, a prestigious school with a thousand years of history.

Here, Kyle has a very fulfilling life. Apart from studying every day, he also uses his spare time to grow a la carte, grow some flowers, or go to the dark underground secret room to give psychological counseling to a small animal that has been abandoned for thousands of years. .

Dumbledore: Kyle is a good boy who is upright, brave, kind and sincere.

Professor McGonagall: The principal is right, Kyle never breaks the school rules.

Snape: Ah yes yes yes...

Quirrell thought so too, but one day, he pushed open the trap door and jumped into a room full of biting kale...

Dementors are evil magical creatures that have no facial features and can only distinguish living people by smell and the emotions floating in the air.

Wherever they go, all happiness will disappear, leaving only the deepest fear in people's hearts.

Legend has it that under the hood of the Dementor there is a face that can devour souls...

"That's the theory."

Cohen Norton did not deny this.

"But this doesn't affect my desire to be a good person. No, it's weird."

As he said that, Cohen licked the lollipop in his hand and turned a blind eye to the child next to him who was crying because the candy Cohen's brother gave him suddenly disappeared.

[Ding! Goodwill value +1, sin value +1]

[Note: Giving candy first and then snatching it is immoral and you will be condemned by your conscience]

(This is a story about a funny person who travels through time to the magical world, becomes a subject of some evil black magic experiment and grows up positively and healthily - just listen to it seriously)

- The following is an incomplete introduction -

"What is this, Tom Riddle's diary? There's a soul in it, take a sip."

"What is this, Slytherin's locket? Pry it open and take a sip like an oyster."

"What is this, Hufflepuff's cup? Add some milk tea and take a sip."

...

"What is this, Harry Potter? You smell good, bro, sip--"

"Cohen, don't come over here!"
