Yi Lin, a genius student from Blue Star, dreams of finding the way to immortality by learning the cultivation methods from ancient books.

He grew up in a low-key manner and became the director of a library, reading and referring to various books every day.

I accidentally traveled to the continent of Teyvat in a game I had played before, "Genshin Impact".

Some big guys are carrying out the Red Revolution here

Some big guys are doing a Renaissance here

Some bigwigs here are in charge of the seven countries and various sectors of government

Some big guys started the industrial revolution here

Some opened shops, some engaged in scientific research, some did beauty work, and some fell in love...

Yi Lin thought of the various Genshin Impact light novels he had read before, and couldn't help but sigh that all the senior time travelers were indeed very talented.

Why don't I come here and try to change the cultivation system?

Genshin Impact, start!

The Teyvat dimensional upgrade plan has officially started!

PS: The plot may undergo major changes. A training craze has been set off in Teyvat and everyone is like a dragon, breaking the original fate of Teyvat and eventually the world will be upgraded!

(Liyue/Human, not a demon god/Double heroines Heulia + Buyel)

(The emotional line is less described, and the focus is on career development)

(The author cannot modify the label without a female protagonist, and the system can only automatically modify it regularly. Please bear with it.)

More than ten years ago, a child fell from the sky in front of the Rock King. When Morax saw the child, he frowned for a long time: "What an ugly child..."

More than ten years ago, Zhong Gui fell from the sky. The first person he saw when he opened his eyes, and the first thing he said was that he was jealous of her beauty. Zhong Gui was determined to stick to him for the rest of her life, eating and drinking his food, and even eating him out of money!

Everything was going smoothly until Zhong Gui returned from his travels in the seven kingdoms.

Zhong Gui: Am I engaged?

Ganyu: When did this happen? How come I have a new fiancé?

Shen He: Senior sister? Why is she here?

Hu Tao: This is my adopted husband. Where did you come from? Zhongli, Zhongli, they're bullying me!

…

Then, you need a tool to travel to other worlds!

Chat Man: Here I come!

Lin Fan traveled to the continent of Teyvat and inherited a grocery store in Liyue Harbor at the beginning, intending to just let it run wild and get by.

But one night in a warehouse, he found a blue-haired girl who was unconscious due to overtime work and had a beautiful sleeping face!

[Ding! The Human Fireworks System has been activated! Goal: Let Ganyu sleep peacefully. Reward: God-level talent!]

From then on, his shop became the strongest shelter and holy place for slacking off in Teyvat!

Guests from the Wangsheng Hall come to buy things on credit every day, and they always ask, "Put it on the Wangsheng Hall's account."

The demon-slaying sage Xiao squatted on the roof just for a bite of almond tofu.

Qixing Secretary Gan Yu stayed on his bed and begged for a refill of refreshing flower tea.

The clever Walnut always wants him to book the Wangshengtang set meal in advance!

When the vortex demon attacks, Liyue Harbor is in danger.

Lin Fan hung up a sign that read "Closed Today" and said helplessly to the "ordinary" customers in the store:

"Mr. Zhongli, stop dishing out walnuts. Your (former) subordinates are about to be drowned."

"Ying, stop playing games. It's time to unsheathe your Wuxiang sword."

"And Wendy, stop pretending to be drunk and get up and work!"

He just wanted to be a quiet shop owner, but these big-name customers were all hidden top gods?!

Meng Xing, after a second time travel, arrives in Teyvat with a maxed-out combat account, expressing his desire for a retirement life free to do as he pleases! Follow your heart, focusing on achieving enlightenment through a single thought! The regrets of the Liyue immortals? Make amends! Resurrect my... ugh. Guizhong, the immortals, the Yakshas, ​​the Great Compassion Tree King, your souls have returned! Return when I tell you to. Break the game with violence, focusing on a no-holds-barred approach. Winter? Monsters? Abyss? Heaven's law? Too lazy to even think about it!

Welcome to the Ninth Art Arcade, connecting all worlds!

Here, you'll find

Walnut, the head of the Hall of Rebirth, counting the zombies on her way to survival and tracking the progress of the Soul-Saving Master.

Kiana, the most powerful (and future) Valkyrie, faces her inner self and conquers her fears in Silent Hill.

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")

Chu Fan, who traveled to the Holy Grail War, knew no magic. But Chu Fan remained unfazed, for he carried with him an FGO system. What? You're going to such great lengths to summon a powerful Heroic Spirit? Ah, I have three Saint Quartz and can summon one instantly, with no limit on the number. What? You're so precious with your Command Seals that you dare not use them carelessly? Ah, my Command Seals refresh once every day at twelve o'clock, and they won't disappear even after all are used. What? You're telling me you're banding together to take on me? Chu Fan snorted coldly, then waved his hand, and dozens of Heroic Spirits appeared around him. "I heard you're trying to outnumber me?" (This story and characters are purely fictitious. Any similarities are purely coincidental. Do not imitate.)

I, Youqi, am a puppeteer. I am good at drawing character designs with telekinesis, and making puppets that are based on real people and are 100% restored.

"So, this is why you make puppets for us?"

Looking at the blue-haired boy, Yakumo Yukari narrowed her eyes and said with a smile.

"No..."

"No what?"

"Not just yours."

"Go to hell!"

PS: I was originally going to name it [Re: Moe Girl Guardian]~

PPS: This fox's custom is to start the infinite flow with Gensokyo as the beginning, and the main world [Gensokyo + Nura + Others]

A website called "Projection of All Realms" has been appearing in various worlds for some time now. As the scenes unfold, they have stirred the blood and moved countless people, causing a transformation to occur throughout the myriad realms…

Even though he has awakened the "Wish Magic", Noah can only fulfill the wishes of others.

[Natsu wants to eat meat, the reward is fire resistance]

Xiaoyu wants some pocket money to buy a Super Moose plush. The reward is the Shadow Queen's blessing.

[Lonely Yugi Muto wants to make friends, the reward is the trap card "Holy Shield"]

[Navy hero Garp hopes to gain excellent parenting experience, and the reward is Armament Haki]

Great White Shark Tiandao hopes to have a long-term supply of good tea to practice Tianwu Tea Ceremony. The reward is the gradual awakening of magnetic field power.

[Matou Sakura prays for salvation, and the reward is a piece of evil black mud]

………

After responding to other people's wishes countless times through the "Wish Magic", Noah suddenly realized that he was standing on top of the world.

And all of this started from that bustling magic guild.
