Kieran Silver is a young man who suffered from the deceit of his superiors. His outstanding talents and exceptional prospects to climb to the top of Zenith Online dismayed his superiors.

They invoked their influence to suppress his uprising, ultimately causing his demise. However, rather than perish, Kieran Silver receives a second chance.

A chance to dethrone one of the top 10 guilds, Golden Brigade. An opportunity to create an immortal legacy that would forever live on in players' minds. The ability to reach the zenith in both worlds!

However, as he is reborn, Kieran notices a few things that are different from what he remembered. Could it be that he has gone back in time, or is there an even deeper explanation and a larger power at play?

These questions will be answered, whether forcibly or inadvertently, as Kieran explores a seemingly driving force.

The advent of the Legendary Berserker begins!

“I'm one game away from reaching the master rank! I'll do it tomorrow, though. A true gamer knows when to refresh his mind and increase his victory chances!”Adam smiled in anticipation as he went to sleep on this special day.However, he could never have imagined the surreal awakening that awaited him.“What's wrong with my voice?!”“Claws? A tail and horns, too?”[Welcome to the demon realm. You have been selected to reincarnate as a Lord. Conquer this realm of fire and ashes, become its uncontested ruler... or die trying.]Reincarnated as an imp in the cruel demon realm, at the borders of the mythological demon Baal's territory, his life seemed doomed from the start.However, determination sparkled in his eyes as against all odds, he defiantly proclaimed.“No matter who decided to make me start as an imp, watch as I turn into a veritable devil. Even Baal won't hold a candle against me in the future!”Equipped with his unique talent, he started his lord's journey, ready to evolve and prove to those strange realms that demons were more than violent and deceptive creatures... at least he would try.

Thousands of years ago, a small planet collided with Earth and destroyed the world. In five days, ninety percent of humans had been wiped out, leaving behind the last ten percent to earnestly struggle on death’s door.

Jinyu was one of those people who survived. Due to a special heredity trait, he could understand beast language. After the apocalyptic disasters, Jinyu had been living for a month with the few small beast brothers that he’d subdued. Previously, Jinyu had thought that he would live like that until he died. Yet, inexplicably, one day he opened his eyes to find that he was in a monstrous, lawless world that was full of vitality and life.

Jinyu’s transmigration into the future let him skip over almost one hundred thousand years. In the year 106825, beasts rule the galaxies and ‘pure’ humans are extinct. As the one and only ‘pure’ human left in the entire universe, Jinyu braves this new chaotic world to find a place for himself and thus begins to work at Beast Store number 138.
