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?]

After transmigrating into the Marvel universe, he becomes Peter Parker.

At first, he thinks being Spider-Man—often called the "Little Hulk"—is a pretty good deal.

But fate seems to be playing a cruel joke on him.

The sudden appearance of Spider-Woman completely shatters his wishful thinking.

He doesn’t want to be sacrificed!

Until…

He discovers a completely different life script hidden in the farm left behind by his parents!

…

Years later.

The sky tears open as a massive wormhole appears.

Thanos, wearing the Infinity Gauntlet, confidently leads his "invincible" fleet to Earth.

The next moment, a figure streaks through the air—

With a single punch, Thanos is sent flying!

“You shouldn’t have invaded my Earth!”

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...

Xiao Fan traveled through the world of fighting spirit, bound to the sign-in system of all worlds, and gained extraordinary enlightenment at the beginning.

Not only that, he was also invited to join the Wanjie chat group.

With double cheats, shouldn’t this take off directly?

Xiao Fan developed steadily in the Dou Qi world, and struck hard in the chat group world. He broke through the Dou Emperor realm before Xiao Yan, and the name of Thunder Emperor resounded throughout the heavens and myriad worlds!

Su Xiaoxiao: The omniscient and omnipotent immortal? No, I’m a fangirl of Thunder Emperor!

Ip Man: With the might of the Thunder Emperor, I can beat ten thousand of them now!

Zhu Yuanzhang: Thank you, Thunder Emperor, our Ming Dynasty has become a place where the sun never sets!

Kanan: I’ve already washed and am waiting for Thunder Emperor to come!

Xiongba: I caught a divine dragon and presented it to the Thunder Emperor as a mount!

When Xiao Yan suffered the humiliation of a broken engagement, and the Xiao family endured immense shame, when Xiao Yan shouted, "Thirty years east of the river, thirty years west of the river, don't bully a young man into poverty!" At this moment, the elders of the Xiao family remained calm, "Alright then, the bet is on."...

After Xiao Yan went through countless hardships, successfully broke the engagement, and returned to the Xiao family... seeing the Xiao family's foundation displayed by Patriarch Xiao Zhan, "You can make do with these resources like Dou Techniques and medicinal herbs for now, this is..."

Elder Yao: "Little Yanzi, how is your family so rich?"

Xiao Yan: "Master, I don't know either!"

..."Father, tell me this isn't true..."

"No, this is true."

Finally, the author's skill is limited, and there are some questionable or even 'toxic' points in certain settings. I hope readers will point them out in time. Any opinions can be posted for discussion. I am extremely grateful.

The strongest Red Dragon Emperor, one of the three royal families of Kyoto Onmyoji, the essence of the flower blossom courtyard family - the daily day of the Buddha conversion of the flower blossom courtyard.

Get up in the morning, wake up the girlfriends next to you first, and if it's the wife nine-tailed fox Yasaka and the cat and big sister Hei Ge together, let them cooperate with each other to avoid tail knots, and then start morning exercises.

Towards the end of the morning workout, the maid group led by Grefia will come in to help wash and change clothes, but occasionally the maid group will come in early to join in.

After washing up and having breakfast, Dr. Yasaka and Chisato Hasegawa sometimes want to feed it himself, but the normal staple food still has to be eaten, otherwise it doesn't matter if it's full.

After breakfast, we leave for school, but if Janovia and Yuki Nonaka don't show up until before departure, it's best to be with Lias and Mio Naruse, otherwise you'll be able to miss school all day.

As for the afternoon, if there is an arrangement, it is best to do lunch by yourself, even if it is a lunch sent by Senior Sister Zhu Nai, it is best to let the maid group check it, and the same goes for dinner.

Washing up before going to bed is casual, but if you want to go to bed early or do it yourself, don't count on the maid group at this time, their professional ethics should not be able to withstand after a day's test.

Traveling through the Pokémon world, he became the eldest son of the Veil Gym family, Li Shuwen.

He was determined to inherit the gym from his unreliable father. He never thought that the trainer brothers who had known each other for many years through the Internet and supported each other's progress would actually be a blonde beauty.

On the day of passing the Alliance Gym Leader Assessment, the blonde beauty appeared with flowers in her hands.

Li Shuwen was shocked. "My brother is Shirona? And she confessed to me?"

Is this what it means to have a double harvest in love and career?

Bro, you smell so good!

Ethan's soul was thrust into the Marvel universe, but unlike many others in his situation, he didn’t receive any overpowered system to guide or assist him. Instead, fate had a different plan.

As he reached adulthood, he awakened as a mutant—an incredibly powerful one at that. His ability? Vector control, a power that allowed him to manipulate forces and motion at will, much like Accelerator. With this, he became an Omega-level mutant, a rarity among his kind.

But Ethan wasn’t content with just existing. He saw the grim fate that awaited mutants and made a vow—to change everything, to turn the tide, and to lead his kind to glory.

Professor X:. "Ethan, I am old. My time is running out. From now on, the responsibility of safeguarding world peace and ensuring the future of mutantkind falls upon you."

Magneto: "Charles, always the diplomat. But tell me, why do you assume you have the first claim? If anyone is to guide Ethan, it should be me. He should inherit my vision, not your dream of coexistence."

After traveling back in time and becoming a prince of Stromgarde, he had a system similar to the human base in Warcraft, so Garen wanted to use this base to change the tragic fate of the Kingdom of Stromgarde, and even the human world, Azeroth. So he started the road of building up his army, united with the human prince and the high elf, won the second war against the orcs, trained Thrall, started eating, sleeping, fighting trolls, conquered the hundreds of tribes of Azeroth as his war vassal army, colonized Draenor, and defeated the legendary journey of the Old Gods. ...

Fourteen-year-old Su Chen just wanted to be an ordinary mortal and live a good life.

It’s a pity that he was born extraordinary!

His body is immortal and his cell activity is terrifyingly extreme. Even if his body is so damaged that only one cell remains, it can quickly proliferate and regenerate.

His genes are constantly mutating and evolving. All external stimuli and all the enemy's attack characteristics will prompt him to evolve corresponding means of restraint.

In a word, it is impossible to hurt Su Chen a second time using the same method.

In order to better summarize the countless abilities that are constantly emerging in his body, he even created the concept of a system to summarize how many abilities he actually has.

Even Su Chen himself knew that as time went by, he would become omniscient, all-knowing, and omnipresent.

By the way, this kind of existence seems to be called 'OAA' in this world.

I can only...
