I lived a mediocre life. Trapped in the simulation of everyday mundanity, the 'Matrix' you might call it. The world killed my dreams, hurt my innocence, but I moved on just fine, struggling everyday to keep living.Until it came out of nowhere, without warning: The Apocalypse.I fought to survive. I lived alone in a world where all dead humans turned to undead. But, there was only so little the average human could do against creatures with superhuman strength. So I died. It was the end.Or was it?“From one cage to another.”I opened my eyes to a world where normal reasoning was as good as garbage. A world ruled by men with superhuman strength. A medieval world with swords and... No magic. Just swords and weapons. But still, that medieval world was not so medieval. It was a crazy place, a world that I couldn't fully understand.So I decided. I'll live because I lack the resolve to end myself. I'll live because i'm a coward. I'll live because in the end, I'll die of old age anyway. But before I die, I'll figure out the truth and secrets of this world. Just for the sake of it.And what's the best way to see the world in its entirety? Of course, it's to stand at the highest summit. And that's exactly what I'm going to do. So watch me rise.
