"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.

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?"

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...

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

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!

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.
