Chen Yu, he has many identities.

He is a gamer and a student at Hogwarts.

He is Tony Stark's savior and is also respected as the Second Supreme by the wizards of Kamar-Taj.

He was the victor of the Fourth Holy Grail War and El-Melloi II's student and greatest patron.

He was given the three Unforgivable Curses at the beginning and almost entered Slytherin.

His biggest dream is to explore the magical mysteries of different worlds.

What I want to do most is to fire an Avada Kedavra light cannon at the enemy.

"Attention, attention! Everyone, look over here, follow my lead. I have an announcement to make!"

"I, Chen Yu, the Sword Master of Avada, come and fight me if you don't agree!"

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!

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.

Originally titled "HP: I Died Early and Passed Through the World"

Faye was sickly since childhood and had to stay in the hospital ward all year round. She died when she was less than ten years old. After her death, she was bound to a system and traveled to the magical world.

Little Faye remembered the system novel that the nurse sister had read. The system always assigned various tasks, and there were penalties if they were not completed. She couldn't help but feel a little worried.

The system said: "We are a regular system, not some wild system with a punishment mechanism!"

... ...

Later, Xiao Fei's relationship with the system was indeed as the system said, free and unrestrained. He would often appear from one corner and then disappear to another.

One day, while wandering the castle, Faye saw a fluttering black robe. Having heard so many fairy tales from her family, Faye thought to herself, "Oh! That must be the most perfect wizard!" So she followed...

From then on, the black-haired, black-eyed professor who was the most feared by the students at Hogwarts had a "little tail" with a completely different style beside him...

"Little Tail" would give him his favorite Christmas presents, would accompany him quietly while he brewed potions, would tell him to love himself, and would even use his little hands to "slap" his head when he unconsciously belittled himself...

... ...
