Fight, survive, adapt, and rely only on yourself. That is Derek’s creed and what's got him through the System Integration on Earth. Everything changed when the System came. Cute bunnies and beautiful butterflies became savage killing machines. Then the Invaders arrived with a single goal: to obtain ownership of this new habitable planet. War has raged ever since. None of this mattered much to Derek, aside from making living a little more perilous.

Humans have been pushed to the brink of extinction by an ever-evolving demonic threat. Portals are opening faster than ever, Towers are bursting into the skies, and Dungeons are being mined below the last safe havens of society. The demons are winning. Quest Academy stands defiantly against them as a place to train the next generation of Heroes. The Guild Association is holding the line but is in dire need of new blood and the powerful abilities they could bring to the battlefront. To be the saviors that humanity needs, they need to surpass the limits of those that came before them.

An AI calling itself Schema has assimilated Earth into its System. As a consequence, everyone gained access to status screens, power-ups, and skills. This AI turned these concepts from fiction to fact. It's easy to become intoxicated with leveling up and becoming stronger. To some, it's too good to be true, like living out a dream. For Daniel, however, it's closer to a nightmare.

Nathaniel's bus ride was supposed to be just another boring commute. Wrong. Now, he, 23 fellow passengers, and a corgi named Biscuit, are stuck in a "Hell Difficulty" Tutorial, battling monsters and leveling up to survive. Easy difficulty, anyone can handle.

With his terrifying talent for mana manipulation, Nathaniel decides to invest every stat point into mana.

Zane was driving home from work when the world changed. Thousands of dungeons spawned at once, taking up every inch of Earth—including the road he’s driving on. He wakes up to a totaled car and a broken leg, facing down a goblin trying to spear him through the guts. And that's just the start of it. But to Zane’s surprise, he finds himself enjoying this brutal new world. While others cower and hide, he goes on the hunt.

Silas is inducted into the System, becoming the last in a long line of Earth's "forerunners." The rewards are great, but the danger is greater. We are not alone in the universe. The fate of five worlds hangs on how their forerunners perform. Will Silas have what it takes to win Earth a place in the multiverse? Or will Earth become another mining world stripped of all resources and left a barren husk floating in the cosmos?

Multiverse Z came knocking, snatching all the humans from Earth to integrate with their game-like realms of magic. No warning. No tutorial. It's an instant transition where eighteen-year-old Joey Eclipse is thrust from his relaxing night playing video games to a stone room with two doors. There's nobody but him.

Joey made his choices, choosing the path of a Great Adventurer, a limited and special category. A unique profile is designed for him.

The system came. The apocalypse ended. Now new worlds have merged with Earth. For Bain Lee, it means leveling his Ocularist class beyond its previous limits. With this strange class and the ability to see into the inner workings of the system, he may find the magic skills needed to earn his redemption. Not only that, but he might discover the secret behind the system itself.

It was a day like any other when suddenly the world changed. The universe reached a threshold humanity didn’t even know existed, and it was time to finally be integrated into the vast multiverse. A place where power is the only thing anyone can truly rely on.

But what if he could go back? Hurled back in time, Isaac has one chance to change it all. A chance to warn humanity of their impending doom. A chance to stop the [System] before shortsightedness and lust for power can render humanity extinct.

When the cultivators came to Earth, they destroyed our entire civilization in a matter of hours. Armies fell, cities burned, and that was before the moon turned red and filled our world with monsters. Now, over a decade later, what's left of humanity slaves under the heels of our Qi-infused masters. The luckiest of us might even become one of them, they say—if we serve the Dynasty well enough and harness the power of Qi. But I want none of that. I'm sick of serving, and I want nothing to do with their world. Instead, I want them to pay for what they did to mine.

Larek Holsten is different from most people living in the Kingdom of Androthe, where his seven-foot-tall frame is looked at with suspicion and anger from its shorter residents; but as long as it helps him become the best Logger he can be, he doesn’t let it bother him all that much.
