Young biologist Levid accidentally travels to the Harry Potter world and arrives in Grindelwald's time, his physical age reverting to eleven. "Ding! Binding the host to the Merit System. Perform good deeds and accumulate virtue, and you can redeem Merit Points for rewards! Furthermore, if the host ultimately achieves the Dark Lord's accomplishments, they will instantly become a god." Levid:? ? Years later... Dumbledore: He's a great man. In this day and age, few are willing to sacrifice their own interests to help others. Grindelwald: Nonsense! This guy may be young, but he's unscrupulous to achieve his goals. He's clearly one of my kind! Newt: That young man looks more ferocious than a raging fire dragon, but... why is Kirin so close to him? Tom: Who told you to be the Dark Lord? Sometimes I want to call you a saint! Levid: Saint? Nosed, you're so rude!

Kerry Black is a time traveler. She doesn't have any cheat codes, but she possesses an innate ability to sense and relate to creatures. Her dream is to capture and train all manner of magical creatures. Her goal is to use them to defeat Voldemort, and then live a carefree life. She can't write an introduction; writing is a hobby, practice, and not a livelihood.

Well, this is a legendary wizard from another world. At the critical moment of entering the divine realm, he was inexplicably drawn into the world of Harry Potter by a space-time wormhole. Faced with...

With a single arrow

Haha, the good news is that I traveled to a book I like, "Harry Potter", and there is a system. The bad news is that I used the Eye of God of the original god.

Protagonist: So? Do I have magic?

System: God's Eye has been issued, unlocking the Ice element. You can randomly draw a surname, with a 20% chance of drawing a pure-blood family. Note that non-pure-blood families also have a chance of possessing magic. You can use 10 original stones to unlock the "Pure-blood Surname" lottery? 90% chance of being pure-blood.

Protagonist: ...6. Why am I alone on the shore of Black Lake?

System: Because they've already started sorting into different houses. Ding—, start the main storyline, "Crossing the Black Lake: Start your first mission!"

Protagonist: There's no boat! Hey!

System: Please explore more content on your own.

Protagonist: Can you give me some hint?!

system:……

Protagonist: 6, no sound.

McGonagall and Dumbledore: Why is most of the Black Lake frozen? It's summer, right?

——————————————————

Protagonist: I'll just fight monsters. It's fine if you're not a Genshin monster! Why are you giving me a cosmic monster that's broken into pieces?! Sometimes it's not even that! I...

Protagonist: Why is there someone from another time? Is this Dumbledore's brother? So young, like Voldemort's youth? Huh? What a lousy system!

The system remained silent and just kept issuing tasks.

Protagonist: ...You are just a decoration.

Riddle (Voldemort): You are mine from now on. You must support me! Otherwise, I won't let you go!

Riddle (Voldemort) after growing up: As long as you are by my side, anything is fine

Everyone: He is not you

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...

(Luna started school a year early)

Reborn in the HP world, Ethan White possesses a special ability.

Received acceptance letter → [Magic Resistance +1]

Touch the Old Ghost → [Spirit +1]

Touch Peeves...

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?"

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."

"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.

In the year 1340 of the Shire Reckoning, one year before the departure of the Lonely Mountain expedition, the Grey Wizard had yet to visit the Shire, the Dwarf King was still forging weapons in the Blue Mountains, and the dragon still slept deep within the mountain…

In that very year, a young wizard unexpectedly crossed into Middle-earth, carrying the Hogwarts Sign-in System.

Overnight, Hogwarts Castle rose from the ground, standing tall and majestic on the lands of Middle-earth; flying broomsticks streaked across the skies, becoming a unique sight in this world.

In the wild lands, the legend of a black-robed wizard began to spread silently.

He was a friend of the Elves, a bane to the Orcs, a nightmare to the Trolls, and the lifelong nemesis of the Dark Lord Sauron.

Years later, when the Dark Lord was defeated, the Elves sailed West, and the Age of Men began—Duir, who had signed in at all corners of Middle-earth, looked toward the fabled lands in the West.
