In a blink, I found myself in an unknown land, greeted by the textbox of an unfriendly system. It wanted me to become a great hero, save the world, win the love of the people and all that crap. But this new world already had a hero. Why should I bust my ass and deal with dragons and the unknown for people I didn't know? Let him deal with that. It's his job! So instead of being tempted by the system's nonsense, I chose a simple class. Potion maker. I wasn't interested in cultivating mana and defying the heavens, courting death, none of that crap.

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.

None of this mattered much to Derek, aside from making living a little more perilous.

In a former life, Jack was gifted, meaning he possessed peculiar abilities. If rich folks found themselves in a jam, Jack could use his talents to get them out of it. Where others were sure to fail, Jack's aristocratic clientele could always count on him to finish jobs cleanly, efficiently, and leave no trace, for which his services commanded a hefty fee. But one day, Jack picked a fight with the wrong man and his old life came to an end. But, as it turned out, his story was far from over.

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.

He and his friends Andre, Taylor, and Zed have known each other forever, and swear that nothing will ever tear apart their friendship. Then the Royal Decree comes. With the Dynasty of Dogs invading, and strange monsters appearing in the Hollow Kingdom, a draft has been implemented. Everyone 17 or older is required to be tested for "Potential". If they have it, they will join the mysterious and renowned Ascender Corps. If not, they will be drafted into the Legion as a forced recruit.

Jason Lee came to New York City to see the sights. But his plans quickly change when the Apocalypse Protocol is initiated. Rifts open across the Earth, unleashing hordes of monsters upon humanity. But gateways to dungeons also appear and, with them, opportunity. Finally, there's a system announcement: some individuals will be bestowed with powers and abilities to combat the monsters and protect their fellow humans.

Leading astrophysicist Liam Jackson is participating in a scientist exchange program in Germany when a curveball of universal proportions is thrown at him. Planes fall from the sky, cars explode, and strange particles rain down from the heavens as monsters appear out of thin air. The laws of physics have changed in the world. The fundamental forces of the universe are behaving differently, and Liam needs to understand them if he wants to survive.

Behold the Multiverse! Its countless realms overflow with terrific opportunities and terrible dangers—warring sects, priceless treasures, martial techniques, and all manner of horrible monsters abound. And Dorian has conquered them all. He’s a Godking—one of the most powerful creatures to ever exist. And as he sits from his throne at the literal summit of the world, bored out of his mind, one question comes to mind: what now? Do it all again, of course! But faster.

No one has ever managed to level it, condemning them to the lowest paying jobs and life in a barren village.

Good things come to those who wait. Damien Vale didn’t, and he ended up bound to an Eldritch creature from beyond the reaches of space. It has lived since the dawn of time, seen the world born and destroyed countless times, and wants to be called Henry. Unusual companion or not, Damien was still determined to go to a mage college and study magic. He wants nothing more than to live normal life as a researcher, but if Henry’s true nature is revealed, he’ll be killed.

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.
