After sleeping for ten thousand years, the Xian Qin Empire has become a wasteland, and I, the last emperor, am trapped in the core, barely surviving.

On the verge of life and death, I disguised myself as the ultimate NPC and turned the broken Xian Qin world into a virtual game "Guixu", which was opened to the Earth for internal testing.

Then, a group of the most brutal natural disasters in history came.

They are fearless and keen on infrastructure construction. They dare to rush into the demon forbidden area for a piece of novice equipment.

Looking at the players working frantically for me, I sat behind the scenes and slowly typed out a line of announcement:

[The new expansion pack "Expedition to the Sky" is about to be launched! ]

Cheng Sui transmigrated to the Dragon Clan world. Just as he was about to graduate from Kassel College after four years, a system arrived. But what the heck was this "Naruto Counterattack System"? He was still classified as a perennial Chunin, an ordinary teacher at the Ninja Academy. [Uchiha Sasuke and Uzumaki Naruto are fighting again in class. The Third Hokage is currently watching this with a crystal ball. You need to use reasonable means to resolve this conflict.] [Mission Rewards: Favorability with the Third Hokage, One-Tomoe Sharingan, Uzumaki Clan Physique] Cheng Sui: "???" Looking at Chu Zihang and Caesar passionately slashing at each other, he fell into deep thought. Years later, when the Dragon King roared across the world, and the giant Susanoo rose from the ruins, Cheng Sui, in Sage Mode and wearing a Tailed Beast Cloak, looked down at the Dragon King beneath his feet. "System, is this what you wanted me to subdue..."

What to do when you're out at sea without a ship? Allen: "Steal someone else's." What to do when there's no one on board? Allen: "Dig someone else's." What to do when there are people but no supplies? Allen: "Rob a warship." Treasure, famous swords, Devil Fruits, where do the women come from? Allen: "Brothers, look! There's a transport ship that's practically floating on air, it has everything!"... Transmigrating to the world of One Piece, relying on Baki's cheat abilities to rise to power in the East Blue, starting with just his fists, he steals everything—people and ships. My name is Allen, and I advocate for freedom. (A million-word completed high-quality One Piece fanfiction is already available; readers are welcome to jump in and get crazy!)

Good news, I was killed by a train at home.

Even better news: he's become the navigator of the train.

Even better news is that you can travel to the world of anime by train.

What pioneering and interesting things did you do after becoming a navigator?

She was paired with Kirito.

[Day 1 of time travel, Tokyo, Japan. I'm just five years old. Good news: my family is rich. My childhood friend in a kimono is adorable.] [Day 3, bad news: 1983, Japan's bubble economy is on the verge of collapse. Coincidentally, my family is in real estate...] [Day 10, Holy crap! A system!

Too expensive, using them would only increase medical expenses and compensation costs, don't learn it.] [Year 6, the real estate economy collapses, many companies go bankrupt, but my family's business is booming.

[Pokémon] + [Team Rocket] + [Villains] + [Story] + [Mega System]

Waking up, Whis finds himself a lowly soldier besieging Crimson at Mt. Moon. Facing the "Fighters," he flees at lightning speed, only to be betrayed by his own teammate. In this dark, dog-eat-dog world of Pokémon, amidst the intertwined factions and ambitious Team Rocket, how will Whis rely on himself to climb to the pinnacle of power and escape the miserable fate of being a lowly member of Team Rocket?

At the Kanto Cape, Weiss kicked Zheng Hui into the conversion device, activated the switch amidst the latter's despairing gaze, and exchanged him with Radamanthys.

At the Slowpoke Well, facing the Gold and Silver protagonists, Whis pretends to lead his team away, but secretly he controls Team Rocket's Slowpoke Tail transactions in Johto.

In the Hoenn region, Whis secretly infiltrated Team Magma and Team Aqua to obtain a key artifact for Team Rocket, thus gaining the power to control both gods.

In the Unova region, on the eve of the great battle between Team Plasma and Team Rocket, Whis had secretly defeated Team Plasma N, and Team Rocket achieved a great victory over Team Plasma, successfully controlling most of the Unova region.

...In the shadows of Alola, Galar, and Patia, each region with its own unique character, Team Rocket is quietly spreading.

More of the world's dark secrets lie hidden in the shadows.

Time has passed, and Whis, the chief executive officer of the Johto region and the most powerful weapon of Boss Sakaki, has finally reached the top of the world.

In the comprehensive martial arts world, heroes gather, and legendary stories unfold right around you.

At Xingyun Manor, there’s the plum thief; at Jile Tower, the investigation of silver notes; at Wudang Mountain, the centennial banquet; at Yujian Manor, the red dragon’s roar...

“This world is already interesting enough, but I think it can be even more interesting!” Zhou Ming said.

So...

“The Wood Daoist is dead, and you picked that Zhang Zhenren! From now on, call me Gin!”

“Have you heard of the legend of the Seven Swords?”

“Today, I’m taking her away. Let’s see who dares to stop me?!”

“I am Monk Fahai, returning from the Great Western Thunder Temple. Everyone, are you willing to listen to my teachings?”

At first, Zhou Ming just wanted to have some fun, but later he realized he was speeding down the path of becoming the mastermind behind the scenes.

That day, the nine continents and four seas all came under his control.

Zhou Ming sighed deeply: “You really have made my life difficult!”

Ghosts and monsters in the darkness spy on the human world.

In unseen corners, bloodshed and cruelty quietly grow. Ghosts eat men, men slay ghosts—millennial legends and grudges are intertwined with fate...

Forming a bond with a woman will earn you rewards; forming a bond with a noble woman will earn you even more rewards.

Having experienced two consecutive time travels, Li Zhihui finally awakened his system, but he ended up with an unorthodox one.

"So, it's really not that I'm promiscuous, it's just something that can't be helped."
