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.

In just seven days, the world will crumble. The System's Descent will usher in a new era of chaos: wild animals mutating, monstrous creatures emerging, and the cessation of modern technology. Humanity will be left defenseless. Drew Wright knows none of this. At least not until he is rudely ripped from his bed and thrust into a white room to undergo a taser-happy ‘Tutorial’. Turns out, he is one of a thousand randomly selected people to be forewarned of the approaching apocalypse. Now, he faces the delightful task of convincing his wife and mother of the devastation hurtling towards them.

Arc was an ordinary young woman from Earth when she was summoned to an icy hell where she fought for her survival in the name of training to become a hero. Now, after defeating the Overlord itself and achieving the status of hero, she leaves with the goal of enjoying her freedom. She arrives at Arlas, a fantasy world with magic and monsters, a world with numbers, tiers, and classes, a world governed by the System that summoned her.

Jack Rust was a disillusioned biologist with a PhD—almost. When an extraterrestrial AI calling itself the System invaded Earth and thrusts it into a world of aliens and violence, the least Jack hoped for was gaining access to magic.

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.

Due to unusual circumstances, Randidly starts in an isolated dungeon far beyond his level, forced to rely on the mysterious Traveler Shal in order to learn and survive with the dangerous new status quo for his world. But survive he does, only to leave the dungeon and discover that while he experienced several hellish months in the dungeon, only half a day passed on Earth. Randidly's capabilities are now more than enough to help build a small enclave of survivors, but that doesn't mean balancing his sense of responsibility against the plots of an unfriendly town will be easy.

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. He unlocks a unique Berserker skill—the more damage he takes, the stronger he gets.

Matt plans to delve the rifts responsible for the monsters that destroyed his city and murdered his parents. But his dreams are crushed when his Tier 1 Talent is rated as detrimental and no guild or group will take him. Working at a nearby inn, he meets a mysterious and powerful couple. They give him a chance to join the Path of Ascension, an empire-wide race to ascend the Tiers and become living legends. With their recommendation and a stolen Skill, Matt begins his journey to the peak of power. Maybe then, he can get vengeance he seeks.

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.

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. The system messages asking some cryptic questions: [Adventurer or Commoner?] [Greatness or Steadiness?] And more. Joey made his choices, choosing the path of a Great Adventurer, a limited and special category. A unique profile is designed for him.

Max was murdered, but now he is mostly over it. Living on earth as a recent college graduate, he can still perfectly recall his past life on the fantasy world of Albion before that. He'd been hailed as the "Hero of the World" after crawling his way up from poverty, eventually enjoying great fame and luxury. But on mana-starved Earth, he's just a guy.

Legends speak of wizards with the power to rival Gods. To Hump, it’s just a story. Apprenticed to a wandering wizard, he grew up on the road, following the coin on whatever quest it took them. He always believed his master was just an ordinary hedge wizard, until the old man suddenly died, and his book of spells bound to Hump’s soul. Knowing no other life, Hump takes up his master’s staff and heads out alone into a world of dungeons and monsters. So begins the path of The Wanderer. The White Flame. The Hedge Wizard.

I used to be the greatest Earth Mage in my world. The head of the entire Order of Architects. But the older you get, the more you come to realize that at some point, you need to retire, so that you can have the chance to enjoy a peaceful life and to cede your place to the young, some of whom have already turned two thousand years old . . .So that's what I did. But I failed to account for one thing: during the course of my long life, I'd accumulated too many enemies, and they had decided to spoil my retirement. So they died along with me. And I hope their deaths were final. But mine was not!
