Traveling to the time and space of One Piece, Li Xuan holds the Supreme Simulation System. The closer the character he imitates is to the original, the more powerful the abilities he gains.

Assassin's Shadow Seven, Uchiha Clan Madara, Arrancar Ulquiorra...

Warring States: Where is the Xuanwu Kingdom hiding? What kind of horrifying conspiracy is hidden behind the Assassin's Alliance?

Five Elder Stars: The Akatsuki organization is undoubtedly a terrifying force that surpasses all the Four Emperors combined, and its power is immeasurable!

Red-Haired Shanks: So, the powerful enemy we face together actually comes from the realm of nothingness?

As the different characters played by Li Xuan appear one by one, the people in this world suddenly realize...

The "truth of the world" that they once knew seems to be gradually revealed...

[Under One Person + Gender Change + Fireworks (The Ultimate Venomous Fun Person) + Extreme Joy + No CP]

Just because of seven consecutive fireworks, Luo Yun was sent directly to the world of "under one man" by the God of Fun Aha. He changed from a 185cm male college student with abdominal muscles to a 145cm little loli who looked like Fireworks. He was also bound to the Chosen Fun Person System. As long as he played the role of Fireworks and gained pleasure, he could unlock new abilities and continuously improve his strength.

Thus, a quirky girl, an outstanding drama master, and a dangerous masked fool appeared in the alien world. She was not interested in wealth, status, and power. The only thing that made her take action was [fun].

She fooled Zhang Chulan, played tricks on everyone in Quan Xing, and even made the Ten Lords dizzy. She gained endless joy from the grand dramas she directed, one after another.

Zhang Chulan: "Hua Huo, you are not a human! Give me back Pella!"

Xia He: "Damn it! Why is Hua Huo prettier than me?"

Wang Ye: "This girl is really good at playing games. She even deceived herself!"

…

Playing Hanabi? No! From now on, I am Hanabi!

What is joy? I am joy!

Ahahahahahahahaha!

Ahahahahahahahahahahahahaha!

"So, Xiao Ke, how did you join the company?"

"Me? I think I'm a refiner."

Zhang Chulan looked at Liu Ke who was hammering iron sheets and making a red mecha, and couldn't help but curl his lips.

"What kind of refinement is this? Do you think I haven't watched Marvel?"

After transmigrating the heavens,

Yang An realized… he didn’t just cross into one world.

With a single body, he manifests into thousands.

With unified will, his mind handles countless tasks.

Tomb-Raiding World: Cursed by the Mountain-Moving Sect, he travels thousands of miles back to his homeland — to battle ancient gods.

Strange Tales (Liaozhai) World: As a mere mortal, he suppresses demons and spirits, ends the decaying dynasty, and ushers in a new era of humanity.

Marvel World: Hidden in the shadows, he builds a golden age of superhumans and seizes control of the world.

Some admire him, love him, and see him as hope.

Some hate him, fear him, and treat him as a heretic and a monster.

In the end, Yang An forges an immortal name across the worlds!

When Liu Neng woke up, he found himself a nine-year-old kid, and he had picked up the title of "Marquis of Qingshan" for free!

But before he could be happy, he discovered——

This marquis was extremely poor. His fiefdom consisted of three barren mountains with no one living there. He had dozens of people in his mansion who depended on him for support.

What's even worse is that the old servant sacrificed his life to buy him an identity. If the truth is revealed, the whole family will lose their heads!

Just when he thought he was going to starve to death in the late Eastern Han Dynasty, the golden finger awakened - the God's perspective map!

"Wait, this dark thing underground is... a coal mine?!"

"That dark color on the mountainside is... iron ore?!"

"There's saltpeter at the foot of the mountain?!"

In this era when iron tools were scarce, Liu Neng, who held the mineral vein, smiled.

Is Liu Bei still selling straw sandals? Is Cao Cao still a gangster?

Sorry, I, the Nine-Year-Old Marquis, started mining first!

Iron smelting, salt making, gunpowder making...

When troubled times came, while others were still worrying about food, Liu Neng had quietly built his own industrial empire!

"Yellow Turban Army? Let them come. It's a good opportunity to try out my new weapons!"

"A melee among the princes? Sorry, my miners' army specializes in dealing with those who disobey!"

From a down-and-out marquis to the richest man in the Three Kingdoms, in this chaotic world, I will use mining to carve a path to heaven!

Ten years ago, Ji Luo awakened a talent that could take away the abilities of other evolvers. However, after ten years of searching, he never encountered any other evolvers.

Until... one day, Ji Luo came into contact with a girl and suddenly gained a superpower called [Death Return]!

Naruto World: When Orochimaru looked at me with his burning eyes, I felt something was wrong.

One Piece World: When Long saw the revolutionary book I wrote, the look in his eyes immediately became strange.

Uncle Jiu’s World: When Uncle Jiu saw me drawing the talisman in the void, his expression became strange.

Magical world, one person, martial arts, Cooking Master Boy, Death.

At the same time, he traveled through the 99 world series and was nicknamed "Brother Cheng". The plug-in was himself.

Hokage Yang Cheng: What! Red Bean is my teacher? Then Aunt Snake is...

Devimon Yangcheng: I just want to be a kind Devimon, but the chosen children are stupid!

Shijiao Yang Cheng: Battle of wits? I've reached my combat ceiling, so why not just speedrun?

Pirate Yang Cheng: Nami is my adopted sister?

Yiquan Yangcheng: What? I'm a tentacle monster, so it's okay...

Bleach, One Piece, Naruto, Digimon, Pokémon, Re:Zero - Jobless Reincarnation, Shakugan Shana, there are so many, I'll just write whatever comes to mind...
