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.

[Location: Aman. Would you like to sign in?]

Adrian Wisen, who traveled to the world of Harry Potter, didn't have any big ambitions. As a professor at Hogwarts, his daily routine is to take care of children, farm, and cause trouble for the elderly headmaster. Everyone who knew Adrian Wisen also knew that he was a kind and amiable wizard. Oh, there is one important thing. Never go near those plants he grows!

"Dumbledore, hasn’t he already graduated? Why is he back at school?"

"Oh, Severus, don’t be so nervous. He’s the new Defense Against the Dark Arts professor!"

"Damn it! If I catch him using a cauldron to cook hot pot at school again, I swear I’ll duel him!"

...

"You are the worst class I have ever taught!"

"But, Professor… isn’t this your first class?"

...

"Miss Granger, as the study committee leader, you’ll guide everyone to read by the Black Lake every morning."

"Mr. Potter, as the sports committee leader, after reading, take them for a run around the Black Lake!"

...

"The countdown to the O.W.L. exams is 100 days!"

"Break the cauldrons, sink the boats—fight for full marks on the O.W.L.s!"

Douglas Holmes, a Hufflepuff with an Eastern soul, returns to Hogwarts three years after graduation to apply for a teaching position—

and brings a whole new style to the school.

Traveling through the Doupo world, the plug-in is a diary. Chu Xiao was full of black lines: "Who writes a diary?"

Writing a diary can reward fighting skills, fire treasures, magical powers of the world, and everything else?

"You are really good at judging people!" Chu Xiao said that he is not serious at all.

Knowing that I will be seen, I have read countless books, but can't I make up a little story?

As a result, the style of painting in the Douqi Continent and even the entire world has changed.

Xun'er: "The men chasing me are from Zhongzhou to the Jiama Empire. You treat me as air. Go and soak a snake. I will beat her back to make snake soup."

Medusa: "What do you mean by being with this king is an obligation? You are cheap. This king will tie you up and bring you back to be a son-in-law."

Xiao Yixian: "Accompanying is the longest confession of love, but you dare not give me a name. Isn't it bad to bully my evil poisonous body?"

Yun Yun: "You said I was your first love. You destroyed the Yunlan Sect without mercy. Let me destroy it again as the leader of the Hua Sect?"

Han Yue and Han Xue: "Explain what super doubling means." Su Mei, Cao Ying, Huo Zhi...

Good news: I have traveled through time and space and reborn. I will live another life and be free and unrestrained. I have money and women.

Bad news: I was reborn in the Naruto world and I am ordinary. I have no blood, no family, no resources, and I am destined to be cannon fodder.

Good news: I have a golden finger. Can I cash in the future in advance? Overdraw the future? Advance the future? Simulate the future? Who cares!

Enrich the present with the future, and determine the future with the present. Step on the right foot with the left foot and soar into the spiral.

Do you think I am only twenty years old?

Excuse me, I have lived for hundreds of years!

Not enough chakra? I have a future simulation and hundreds of years of growth period.

Without ninjutsu resources, I will get them for free in the future and develop!

Everything is possible in the future!

What? Uchiha...

Like cursed spirits, evil spirits, monsters, disobedient gods, etc.

However, this does not prevent him from having followers.

I traveled through Naruto and became a daimyo at the beginning. The system rewarded me with the power of six paths!

A big name, and having offspring is definitely very important!

Humph, I have both strength and power!
