Apocalypse: did i Just had a hell reincarnation or are i unluck

--- Only a fool would think reincarnation would be the best thing that could ever happen. To stop being just another cog in society… and instead become a legendary hero. To wield unimaginable power. To be surrounded by a harem of mystical beauties. When the opportunity appeared before him, he accepted it without hesitation. After all, who wouldn’t want such a life? To become a hero… To stand at the center of the world… To have beauties on both sides. But what he never expected… was this. Instead of waking up in a medieval world filled with magic and swords, he reincarnated as an alternate version of himself in a small apartment, inside a modern city. A world painfully far from the fantasy he had imagined. And worst of all… His system didn’t even activate. According to the message he received, it required an entire month to recharge before even its most basic functions could begin operating. He didn’t even know what the system actually did. Still… at least this was a modern world. Right? …Right? But soon, something began to feel wrong. The names of the cities. The dates. The familiar feeling he couldn’t quite place. Until the horrifying realization finally struck him. He wasn’t in just any world. He had reincarnated inside an apocalyptic novel. And not just any apocalypse. A Hell-level apocalypse. He only had one month before everything began. One month to prepare. One month to gather whatever resources he could. One month to plan how to survive in a world that shows no mercy. A world that does not forgive weakness. A world that punishes stagnation. A world where survival is never guaranteed. Will his arrival change the course of the story? Or are the events of this world already set in stone? Will his existence become the salvation of this world… Or its final doom? Only time will tell. ---
