Ying Su, a Ravenclaw student at Hogwarts, is a reborn person, a Harry Potter fan, has strong logical thinking, is good at studying, and is an ambitious businessman.

He was reborn into the Harry Potter world, but instead of studying magic, he was always thinking about doing business. He believed that "the wizarding world requires not only strength but also financial resources!"

What? You're saying I'm the prophesied savior of the wizarding world? Are you sure? How about you take a look at my Ten Thousand Souls Banner before you speak? The story of an Eastern magic cultivator attending Hogwarts.

As the grandson of Gellert Grindelwald, Claude was treated as the third generation of the Dark Lord from the moment he began attending Durmstrang. Later, forced to defend himself, he caused a disturbance and was expelled. After transferring to Hogwarts, he enjoyed a pleasant life, but later discovered that the wizarding world was not as simple as he had imagined: traveling across millennia, applying magical rules, possessing artifacts, and even discovering the existence of gods. All of this was due to a wish granted by a god.

After accidentally traveling to the world of Harry Potter, and enjoying his second life in the magnificent wizarding world, Maureen, now the owner of a dark magic shop and known as Mr. Burke, has to find a way to get rid of an employee. Although this employee is young, handsome and eloquent, who made him called Tom Riddle...

The soul of a modern worker-peasant doctor travels through time and space in "Game of Thrones" and becomes the hungry Baron Ion in the Dorne Desert.

While others were still vying for the Iron Throne, he had already dug qanats beneath the sand and created oases with solar stills.

Despite the suspicion of Sunspear and the iron hoof of House Fowler, he used hybrid sand dates and hydraulic hammers to build the foundation of his throne.

See how the tiny baron uses his knowledge to rewrite the rules of the magical continent, making springs gush out of the desert and the iron rose bloom in the yellow sand.

——This time, the chessboard of Westeros is redrawn by scientific and technological thinking.

Cheng Mo's life fell into despair.

My younger sister is seriously ill and her studies are on the verge of collapse...

Until he picked up a mysterious compass, his life took an outrageous turn——

Save Nezuko, accept Tanjiro as his apprentice, and get involved in the dispute between the Demon Slayer Corps and Muzan...

"Wait, didn't you agree to just be a profiteer?"

"My Lord, let's discuss business. I'll sell you penicillin, and you'll teach me breathing techniques, how about that?"

"Ms. Tamayo, I have a report on modern genetics. Would you mind using some of my blood to study it?"

"Muzan? Oh, don't run away with that moving gift bag of time and space coins!"

Cheng Mo just wants to resell resources and make enough money to save his sister.

When he looked back, he discovered that he had already held the authority of countless worlds and became the largest behind-the-scenes supplier in the heavens!

Tanjiro: "Teacher, what is the 'currency' of this world?"

Cheng Mo: "It depends. Maybe it's a devil fruit, maybe it's chakra, maybe... the future of a world."

(This book is also known as: "I Resell Supplies in the Heavens" and "After Accepting Tanjiro, I Became the MVP of the Demon Slayer Corps")

I traveled through time to Doupo, but it seems that I traveled a little too early. The Xiao family was still in the Jiama Imperial Capital at this time. They were one of the four major families, and there were Dou Wang strongmen in the family. At this time, there was no such person as Xiao Yan in the Xiao family. According to the family tree, a family member named Xiao Yan five hundred years ago had his grave not even found. As for Xiao Yan's father, Xiao Zhan, he was still a young boy. The rise of the Xiao family actually fell on a young man named Xiao Li. Many years later, Yao Lao said: "Xiao Yanzi, your family is quite wealthy. Is there a pharmacist in your family?" Xiao Yan smiled: "Of course, my second grandfather is the only pharmacist in the Xiao family, but I don't know what his grade is." Yao Lao: "Oh my God, evergreen vine, snow bone ginseng, blood essence fruit! God bless this old man!" (Single Different Fire: Yin and Yang Double Flame)

Traveling through Doupo Cangqiong, Xiao Chen obtained a heaven-defying system that could replicate everything.

I thought I could easily copy the strange fire and dominate the continent, but the system prompted: Insufficient energy, please recharge first.

In desperation, he had to cling to his fellow villager Xiao Yan's thighs, and by the way, copy some elixirs and skills to barely survive.

Until one day, he accidentally copied the ninth-grade Xuandan. The thunder of the dan shocked Zhongzhou, and the ancestor of the Soul Clan came to his door in person: "Young friend, would you like to pay? My Soul Clan will cover everything!"

Xiao Chen looked at the VIP15 exclusive privilege that popped up on the system interface - [Copy Ancient Dou Emperor], and fell into deep thought...

Traveling across the Dou Qi Continent, Xiao Lei awakens the "Look at You System," allowing him to steal someone's cultivation, skills, and even physical fitness simply by staring at them... Now standing before you is a Heavenly Saint possessing the poisonous body of Hell, the three-flowered pupils of the Green Serpent... the bloodline of the Nine-Colored Sky-Swallowing Python, the bloodline of the Dragon and Phoenix, the bloodlines of multiple Dou Emperors, twenty-two kinds of exotic fire, an Emperor-level soul, dozens of heavenly-grade Dou Skills, Emperor-grade alchemy techniques, and the peak cultivation of a Nine-Star Dou Sheng! Please try to defeat him! Soul Emperor: I...you...this I...

"I am the Legion, I am the Fall..." "I am filth and disaster, pain and curse..." "How dare you be so perfunctory? You actually found a yellow-skinned godfather to deal with me?" "As soon as you get close, I smell the scent of fear, so sweet, so..." "Wait, Houlixie, what the hell is this! The Ten Thousand Souls Banner?!" "Friend, oh no, distinguished guest from the East, my respected Taoist priest, please accept the most sincere greetings from a devil..." "No, no, no, don't let me enter that damn banner, let me go to hell, I promise you anything! God, save me, save me!" Lin Zheng gently covered the other person with the black banner, pressed his mouth and nose, and murmured, "Don't be afraid, dizziness is normal, it will be fine in a while."... Without the Thunder Department, there is no way to summon the Thunder Law? Without the Yin Army, there is no way to summon the Five Demons? Lin Zheng: "Without...
