When the Supreme God of Heavens disappeared, the gods of the Greeks, Norse, Mayans, Egyptians, Chinese, and many more sent their young mortal champions to a magical world in order to participate in the Game of Heavens and Earth on their behalf to win the divine throne. However, the young mortals used their powers, weapons, and tools that were bestowed upon them to form themselves into guilds and create a paradise for everyone. To any kid from Earth, an exciting adventure and new beginning await them, and Sam Roche is one of those lucky chosen ones — or is he still unlucky? Since everything is in peace, Sam tries to build a new life in the City of New Beginning while hiding his dark secrets from his new friends about the sins he committed back on Earth. Eventually, Sam and his friends discover that the strongest guilds have long controlled the paradise, and their rivalry might spark a war that will engulf the land. Wanting to get away as much as possible, they decide that they form their own guild and leave the city. However, a powerful guild is threatening the fragile peace of the magical world in order to win the Game of Heavens and Earth. Sam must either run away to save himself or become a hero to save not only his friends but both worlds.

What if humanity’s cruelest monster is the only one who can save you? In the toxic slums of Sector 4—far beneath the glittering glass domes of the elite city—there is only one rule: keep a low profile and stay alive. Jada is a master of survival. From the scraps discarded by the upper class, she builds everything she needs to exist in this merciless world. But during a brutal raid by the ruling Consortium, her identity scanner suddenly flashes a blood-red alarm. The verdict is neither prison nor death. It is: Sector Omega. Sector Omega is a myth born of whispered nightmares. It is the Consortium’s deepest underground laboratory, where the authorities breed genetically mutated supersoldiers. Jada is thrown into a pitch-black cell as a "calming companion" for the most dangerous experiment of all: Subject Zero. He calls himself Kael, and he is the Apex. An unstoppable beast, engineered for war in the toxic outer world—a nightmare of muscle, claws, and blinding rage. Every woman sent into this cell before Jada never left it alive. Yet, when the monster attacks from the shadows and lunges at her, he suddenly halts. The beast catches a scent. In the rebellious scavenger, Kael sees no prey—he recognizes his destined mate. With a single, guttural "Mine," Jada’s fate changes forever. Certain death transforms into a perilous alliance. Kael vows to protect his mate with his life, while Jada discovers the man hidden beneath the monster. To escape the cruel Consortium, they must ignite a bloody rebellion together—one that will shake the dystopian world beneath the dome to its very foundations. For an Apex does not share. Tropes: Sci-Fi Dystopia, Werewolf Romance, Fated Mates, Touch Her and You Die.

He was supposed to be nobody. Born with crippled spiritual roots in the weakest corner of the Mortal Heaven Continent, he spent his early years mocked by peers, dismissed by elders, and written off as a waste of a bloodline. The world had a plan for people like him — obscurity, mediocrity, a quiet death at the bottom of the cultivation ladder. Then the System arrived. Rude, chaotic, and absolutely unhinged, the Infinite Chaos System begins issuing missions so absurd they border on cosmic comedy — slap an arrogant Young Master, steal from a forbidden ruin, insult a Heavenly Lord to his face. And somehow, at the end of every ridiculous task, he walks away stronger than before. What begins as a shameless scramble for survival slowly reveals something far more terrifying. His talent isn't crippled. It was sealed. His bloodline isn't ordinary. It was buried. And the System that appears to be helping him? It was never designed to help anyone. As he rises from a forgotten boy in a forgotten kingdom to a figure that shakes the foundations of all Nine Realms — and the ancient dimensions lurking beyond them — the truth peels back in layers. The history of the cosmos is a lie. The gods who rule from their thrones are terrified. The first user of his System already conquered everything and nearly destroyed it all. And somewhere at the end of every road, a question waits: what do you do when you've beaten every enemy, unraveled every secret, and the universe itself asks you to become its next ruler? He laughs, pockets another ancient treasure, and causes more problems.
