Alex is a young man who struggles to make a living in the world's biggest game (Ancient world). He works as a mercenary who does every job he can find. It's been five years since his suffering started.

Ancient World creation was only possible by the World's greatest invention, “AI ZERO.”

Ancient World A vast planet Multiple times the size of Earth Ruled by Great empires, Big organizations, and hidden Shadowy associations.

A Fantasy world filled with prehistoric animals that have gone extinct on Earth. The creatures humans have only heard of in fairy tales and old stories, Monsters beyond the imagination of humans, roam the vast lands of the “Ancient World.”

Everything was going well, but it all changed on that day.

When the United States told the World “AI ZERO.” and “Ancient World.” technology was a gift from a very advanced intergalactic civilization. That has surpassed humanity in any way of life by an uncountable margin.

Humanity entered a new era, and the Ancient World became humankind's most important part of life.

Alex joined the game to make a living and support his family, but things didn't go as he had hoped.

After suffering in the Ancient world, Alex returned five years back in time.

Alex knows that the Ancient World is not just a VR game.

Now with a new chance in life, Alex will get strong and reach the top while finding the truth about the Ancient World.

Regret filled Valyr as he witnessed Earth before him crumble into nothingness. Although he and the others had done everything they could, their efforts were all for naught as they stood powerless to stop the inevitable, causing billions upon billions of innocent lives to perish in the cold and unwelcoming darkness of space.

Indignant at the outcome, Valyr asked the heavens above to give him a second chance, a chance wherein he would make sure the inevitable didn’t happen. Though he knew that the likelihood of it happening was slim to none, surprisingly…

The heavens answered.

Opening his eyes, he swiftly found out his wish had been granted, in more ways than one at that. Not only was he brought back to the time where everything had yet to unfold, he was also reborn as an NPC in the game where everything started and everything ended.

The True Immersion VRMMORPG, Greater Beyond.

Utilizing his newfound advantages, in conjunction with his knowledge of the game and its various versions from his previous life, Valyr was going to make sure that what happened before wouldn’t happen again. And all of that began…

With him picking up the Blacksmith class.
