Legend has it that in the metropolis of New York, there exists a "Do-It-All" shop. When you're at your wit's end, it will appear before you. Go inside, write down your needs and the price you're willing to pay on parchment, and leave an address where you can be contacted. If the shopkeeper is willing to accept your request, then…

1. Write down your request

2. Write down the compensation you are willing to pay.

3. Write down your name and address.

IV. Only USD and gold payments are supported.

5. Unconditionally cooperate with store staff

VI. Those who refuse to pay will bear the consequences themselves.

7. If you don't believe me, get out.

[System, Upgrade, Treasure Chest, Cheat Code]

Seven Nights transmigrated, and he brought a system with him.

The system has a cute loli voice, but it only urges Qiye to continue getting stronger.

The world of Naruto...

Eye techniques? Bloodline? Summoning beasts?

The system says it has everything, so it's giving the host an enhanced version!

Impure World Reincarnation?

System: How about a permanent control type Edo Tensei card? No side effects!

The world of Douluo Continent...

Martial Soul? Soul Bone? 100,000-Year Soul Ring?

With the system in hand, everything is a piece of cake!

I've heard that the Asura God breaks the law while enforcing it?

System: Host, get the hell out of here!

The rest of the world is still being sorted out...

Nangong Xiao: "I know more about this other world than anyone else." Asuna: "..." Nangong Xiao: "I'm not cheating, really, why are you looking at me like that?" Kasumi Utako: "..." Nangong Xiao: "Who says a cruel other world can't have a normal daily life?" Maple's eyes lit up: "!!" Nangong Xiao: "War is always the last resort. If you play it like a normal card, things will get very..." Shizuka: "Shut up! You're the main DPS, just focus on outputting damage!!" Nangong Xiao: "Ah, oh, coming right now..."

A familiar, thin figure was standing at the doorway.

He wore a yellow and black square haori, and his long, deep red hair was unusually tied in a high ponytail.

He was holding a katana that he had never seen before.

That was the back view of his father, Tanjuro Kamado.

And facing Tanjuro face to face.

It was a man Tanjiro had never seen before, dressed in a black suit and wearing a small top hat.

Because Tanjiro fell in the snow, he couldn't see the expression on his father's face, who was turned away from him.

But he was able to see the other side.

—The man in the black suit, his red eyes revealing a look of horror.

That was an expression as if he had seen a ghost.

Cheng Feng transmigrated into the world of Fairy Tail. In this world where everyone's combat power is off the charts, Cheng Feng is a little panicked. Fortunately, he possesses the ability to receive magic and also carries a gacha system. With enough money, he can draw cards, and the cards he draws can be used using the receiving magic. This is getting interesting. Paying to get stronger—as long as the money's right, even the Black Dragon will be utterly defeated!

"Hello, I am God."

"Hello, excuse me, where is this place?"

"Never mind where you are, your good brother Li Si has time-traveled!"

"What does this have to do with me?"

"He transmigrated to the Douluo Continent and became Tang San, the protagonist of the Douluo Continent!"

"Now, you have two choices. Press the button on the left, and your good brother will not only inherit the Tang Sect's unique skills, but also gain innate level 20 soul power."

"Press the button on the right, and your good brother will also inherit the Tang Sect's ultimate skills. However, each time you press it, his innate soul power will decrease by one level. At the same time, you will receive one million!"

"Wait, what are you doing?"

"One million per click, I clicked it a hundred times, a small goal, give it to me!"

"He's your good brother!"

"Serves him right for transmigrating into Tang San!"

Gu Luo unexpectedly transmigrated into the world of One Piece and became Luffy's twin sister, Monkey D. Luo.

He was completely dumbfounded at the moment of birth. How could he, a handsome and dashing man, turn into a little girl?

Years later, the world has undergone earth-shattering changes. Ryo becomes the Fleet Admiral of the Marines, Luffy becomes the Pirate King, and Dragon is the leader of the Revolutionary Army.

Blackbeard: "The whole world is taken over by that family, what are we supposed to do?"

Kaido, with tears in his eyes, said: "We're all just tools to help them ascend the throne!"

Buggy the Clown: "I would call Rosa a god, and as for Luffy, get out of here, he's not worthy to be Rosa's brother!"

This era will be rewritten by the Monkey D family!

One day, Luffy said to Ace, "Let's stick to our own way. I'll call you 'brother,' and you'll call me 'brother.'"

[Genshin Impact + Sasuke Uchiha + Role-playing + Time Travel + Thrilling Story + System + Fou]

Jiang Ran was attending a comic convention cosplaying as Uchiha Sasuke when he accidentally traveled to the Teyvat continent while passing by the Genshin Impact booth. He awakened a role-playing system and took on the role of Uchiha Sasuke, whom he was cosplaying at the comic convention.

Many people are changed as a result of this ongoing role-playing journey.

Hu Tao: Ever since Jiang Ran, our guest, arrived, the business at Wangshengtang has become increasingly prosperous.

Zhongli: Jiang Ran's guest advisor? I'm not really good at dealing with him.

Funina: Before I met Jiang Ran, my life was always dull and boring. After I met him, I felt that every day was a new day.

The first 10 chapters are a transition; Fontaine starts from chapter 11.
