But these worlds are nothing like the Earth they once knew.For Yuka, however, this apocalyptic world feels eerily familiar. It is a realm of endless war, devastation, and chaos—a world he once played in a game.

But when he awakens a system granting him a power beyond imagination, he soon realizes that blessings can also be curses.[You have gained Infinite Mana.]Infinite Mana...?What could possibly go wrong?

The Heavenly Demon, Baek Jung-hyuk, woke up as the eldest son of the Dmitry family.

The Heavenly Demon. No, Roman Dmitry, cannot live a normal life.

A phoenix is a creature of legends, a wonder of the world, an imagery of life and destruction. This fabled creature signifies the rise of a hero in a virtual world where battles occur for the sake of honor and glory!

Zhang Yang was a professional gamer in the first and most fantastic game that revolutionized the world: God’s Miracle. A game where traditional knowledge in RPGs did not matter anymore, players would have to manually target and evade attacks, giving rise to a significant gap in skill between a professional and an amateur gamer.

Zhang Yang’s downfall came a little too soon. His girlfriend was snatched, his guild was harassed and disbanded, and he was even driven to commit suicide! Jumping off the top floor of a hotel, Zhang Yang seemed as though he was soaring like a phoenix. Little did he know that the end of his life also signified his rise from the ashes.

Zavier met Cosmic Consciousness after his death. He was satisfied with every system that Cosmic Consciousness exhibited, so he wanted all of them. Surprisingly, the Cosmic Consciousness obliged him.

Zavier was reborn in an isekai full of magic and alchemy. Now, he had many routes to upgrade. Interestingly, to coordinate these systems, Cosmic Consciousness gave him the gift of being able to duplicate himself. He could clone a finite number of himself to manipulate these systems.
