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.

Shikatari Nanatsuki traveled to the world of death and became the younger brother of the first captain Shikatari Takeunsai.

He thought he had a big boss to look up to, but he found out that Lu Qu Ba Yun Zhai was already terminally ill and would not live for many years.

Fortunately, he has awakened the teacher system, and he can become stronger just by teaching.

In order to gain the strength to gain a foothold in this world, Shikatori Nanazuki became a teacher at the Spiritual Arts Academy, and inherited the Shikatori Dojo, working hard to teach.

Many years later, Aizen Sosuke suddenly found...

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...

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...

Gran: "Weiss, I have the most delicious food in the universe. Do you want to try it?"

Weiss: "Trying to trick me into saving you? Don't be silly... It smells so good!!"

Gran: "Mr. Weiss, I want to learn how to break the rules. I want to learn Ultra..."

Weiss: "Don't be silly, how could you possibly learn... What, how did you comprehend the second level of selflessness so quickly? What, you learned to break the rules again??"

Beerus: "Boy, you have good talent, so I'll make you my candidate!"

Xiangpa: "How outrageous! That skinny rib has such a talented candidate!"

Bardos: "This little guy is amazing, he even learned angel control techniques!"

High Priest: "Will Gran surpass me one day?"

...

My name is Ye Xiao, of course you can also call me Abel Astaroth, an ordinary time traveler, and now a pure-blooded demon.

His eldest brother is Beelzebub, one of the four great devils.

Sona is his fiancée and Rias is his childhood sweetheart.

After awakening the memory and activating the system, I found that there is more than just the Devil High School in this world.

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

However, this does not prevent him from having followers.

Jiang Yuan traveled through the world of Full-time Mage, and his soul fused to awaken his heaven-defying dual talents!

Every time he awakened a talent, he would get a unique talent:

Water Talent [Extreme Cold Inferno], Undead Talent [Soul Abyss Domination], Lightning Talent [Thunder God Realm], Psychic Talent [Divine Mind Overclocking]...

While Mo Fan was still shocking the world with his dual talents, Jiang Yuan had quietly risen, and his talent crushed everything!

From Bo City to the Magic City, from the Academy to the Holy City, no one could stop him.

In this life, he wanted to control the origin of magic, subdue the Undead Emperor, tear apart the dark plane, and even the Archangel of Holy Light had to kneel and recite his name!

"Supreme Lord God,

the supreme god who controls the origin of magic,

the supreme ruler who rules the world,

the conqueror of the underworld,

the tearer of the dark plane,

the eternal glory of the Holy Land of Light!

Your authority runs through the heavens, and

your divine power suppresses all worlds.

May your divine light illuminate our way forward,

and may your laws protect us forever!

We pray devoutly and

welcome the Lord God to come!"

Lu Ran crossed the world of full-time mage, awakened the water system and the undead system, and also had a special natural talent. The fusion of the magic system, and the two systems shared a stardust.

The fusion of the undead system and the water system has derived a river that can swallow living beings in the spiritual world of Lu Ran.

The Ming River absorbs living and dead souls, and feeds the mainland.

Under the control of Lu Ran, the Ming River expanded from a trickle several meters long to a vast ocean of millions of miles.

In the peace of Hanoi, hundreds of millions of living beings sing praises:

"He is in charge of the power of the underworld, but the Lord of living beings!"

......

A few years later, the maritime empire in the Pacific Ocean, led by the Cold Moon Eye Emperor, swept through the huge waves and tried to invade the land of Kyushu.

The Seven Archangels of the Holy City acquiesced, but the Kyushu Gods opposed it!

On that day, a black ocean covering hundreds of thousands of miles appeared above the canopy of the demon capital.

In the vast black ocean, there is the cry of hundreds of millions of living beings:

"Those who praise the name of the god of the underworld can prove eternal life in the underworld!"
