"Don't put all your hopes in the 'savior', let me carry the burden!" "Believe me, there is nothing to fear from Voldemort, he was never our true enemy!" Ethan Vincent, winner of the 2008 World War II Award

[HP Fanfiction + Single or Multiple Female Protagonists + System + Snake Court + Behind the Scenes + Slow Heat]

[ps: Don’t join Ron’s party, I don’t like this character]

My name is Leggett Black.

After crossing over, I obtained a system....

It was also from this day that the world began to emit shrill screams.

Tang: Damn it, who stole my true energy!!!

Yu: "Ahhhhhhhhhhh!!! Oh my god!!!"

Jia Zhang: "Old Jia, please come back and take this thief away!!!"

In short, this is a story about exchanging everything in the Harry Potter world...

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!"

The following is a real interview record:

"Professor Evans Kahn, what do you think of the rumors that you are the first generation Dark Lord and the confidant secretly cultivated by Headmaster Dumbledore?"

"That is pure slander!"

Evans stood at the Wizengamot's inauguration ceremony, his face indignant.

"Dark Lord? White Lord? These all sound too scary."

"If there must be a title, I actually prefer the word Beast King."

The next day, newspapers throughout the wizarding world published reports about the third generation Dark Lord changing his nickname.

"Wait, when did I admit that I was the Dark Lord?"

I am a great alchemist and the supreme wizard king in the magic world.

Loki regards me as a nightmare, Thanos regards me as a thorn in his side, Thor... Why do you call me brother-in-law?

You can call me by my name, John Wick.

My motto is: "There is nothing that cannot be solved by your weapon. If there is, add an Avada Kedavra." ...

A few years later

Harry: "Ethan is our best friend. If it weren't for him, we wouldn't have been able to pass Snape's exam."

Ron: "Harry's right!"

Hermione Granger: Actually, I don't know much about him, but I've recently been wondering whether he prefers house-elves or magical creatures in the wild.

Minerva McGonagall: "He is incredibly gifted, brave and upright, and I'm so glad I had him here.

Snape: I hate him.

Voldemort returned from his adventure: "No! Ethan White is the most evil being! I must see Dumbledore immediately! Dumbledore! I am Tom!"

Ethan White himself: "I personally strongly protest against Mr. Tom Riddle's accusations. In fact, I have always wanted to find him to clarify some misunderstandings. Unfortunately, Mr. Tom has always avoided me... By the way, where did you see him just now?"

"Extraordinary wisdom is mankind's greatest wealth. I came to Hogwarts to learn the wisdom accumulated over the years," said Blackley.

What kind of story will unfold when a new friend enters the Harry Potter story?

Dumbledore: "Oh, that little Ravenclaw kid you're talking about. He's a smart kid who's obsessed with knowledge."

Harry: "Blackley is a very reliable man, but he can be strangely persistent sometimes."

Hermione: "Merlin's lace stockings! This is the first time I've seen someone so eager to learn."

Blackley: "Knowledge is the most precious treasure in the world, and I am a goblin with an extreme greed for knowledge. So, Professor Dumbledore, can you really not explain the principle of the Killing Curse? I want to invent a counter-spell for the Killing Curse."

Dumbledore: “…”

Voldemort: "That little wizard is simply a lunatic. He actually wanted to capture me and dissect me for research! He is a lunatic!!!"

This book has many private settings. The protagonist is an orphan in this world. His adoptive father is a super ancient magician and alchemist who has lived for 17,000 years. He knows a lot of ancient magic and ancient alchemy and will teach the protagonist some, but he rarely appears and basically appears to complete the protagonist's character.

[Daily flow, easy, very talented in magic, from the same class as the Weasley brothers, single female protagonist (original), may be a little worse in the early stage, but will improve in the later stage, so please watch it later]

But some vengeance still needs to be avenged.

The last bell of the century has sounded.

The shadows are hazy, and the last demon hunter is chasing the out-of-control werewolf.

The blood moon is in the sky, and the ancient vampires are preparing to welcome the return of their ancestor.

Shrouded in fog, Little Red Riding Hood in Storybrooke is looking for the descendants of Grimm.

Wizards walked out of Hogwarts, "The damned mudbloods are usurping the glory of purebloods."

Groudon tore through the ground, "The thugs from Azkaban are on a killing spree."

Kyogre stirred the waves, "A new Dark Lord is about to ascend the throne."

Rayquaza pierced the sky, "Great Wizard King, Builder of the White Tower, Swordmaster of Gryffindor, Paris respectfully welcomes you."

Allen touched Arceus beside him. The sixteen tablets of creation radiated eternal light. "I'm just a training master who does this out of interest."

Rebecca: Harry, explain why you stood me up last time, honey~ (pulling out the iron gall)
