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?]

In the shadow of the green lantern, Carl tapped Voldemort's diary with a hook stained with evil despair.

"Poor lonely ghost, you are mine, come out and play, how are we going to carry out this pleasant torture?"

On the day when the owl delivered the Hogwarts admission letter, Carl was excited, but also glad that he did not choose "Harry Potter" when he copied books to make money. He was just one step away from biting into the special melon of Avada. After Professor McGonagall arrived, Carl discovered his talent (external plug-in): "Detect Minerva McGonagall, Animagus Transformation... Match Nidalee, Vastaya Xayah Transformation..."

It is understandable that they can transform into a cat, but why did Professor Snape match Viego? "Forever lost my love! Defeat with a single glance!

A reborn Saiyan with an invincible hairstyle, just as his memory awakened, he received a call from Frieza! Of course, Rhodes chose to ignore this! I have been reborn, but if I go back to die, wouldn’t that be a waste of my rebirth? Therefore, when Frieza was planning to wipe out his entire homeworld, Rod had already headed straight to Earth with his loli teammates. Super comprehension, cultivation methods, gravity room, wishing, time house, Senzu card bug, buffs are stacked layer upon layer. Then, he became invincible and started the wave!

Gentle mother, working-class father, born in the Sawada family, living in Namimori-cho.

When he was ready to embrace his future career as a gang leader, he learned that his family was moving out of Namimori-cho.

In Karakura-cho, seeing the orange-haired boy, his small eyes were full of big doubts, why did the boy named Sawada Tsunayoshi come to the world of the god of death?

On the first day of the transfer, how should I persuade my parents to leave Karakura-cho? Very urgent.

(The power system of the god of death is the core, and the power of the tutor is the external manifestation.)

Chu Ge, who traveled through the fantasy world, finally awakened the system eighteen years later.

It was just the name of the system that made him a little unable to hold back.

The villain writes a diary and checks in the check-in system?

What stitching monster?

On the first day of the system, reward the spirit.

On the seventh day of the system, reward the king body.

Receive the system for thirty days and reward the holy body.

As Chu Ge kept writing his diary, changes began to occur around him.

Many years later, facing many lucky sons and the beautiful female fairies beside her.

Chu Ge: "The system misled me! I am really not a thief Cao!"

Qin Chuan accidentally traveled to the world of Collapse Iron, joined the chat group, signed in and obtained the remains of the dragon. Unexpectedly, this power contained the origin of the dragon, and he became the Dragon Lord of Luofu by mistake. Ailixia: I knew that Qin Chuan was the best to me, and I like Qin Chuan the most. Daci Tree King: I wonder if you, Qin Chuan, are interested in becoming my sage, or... the partner of a god? Kinomoto Sakura: When I grow up, I want to marry someone like Qin Chuan's brother. Feixiao: Qin Chuan, do you want me to show you how to do push-ups? Hmm? Face to face, of course. Qin Chuan racked his brains but couldn't figure it out. He just wanted to spoil the plot and save people from the beginning. Um, what are you inviting me to the basement for? Don't come over here! ! !

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!

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

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

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

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