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: ......

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.
