Rebirth in the end times: I reached the top by opening boxes

When the apocalypse finally descended upon the world, the protagonist didn’t die fighting monsters or struggling to survive—he was betrayed and murdered by the very girlfriend he trusted most. Filled with hatred and regret, he believed everything was over, only to awaken mysteriously one year before the end of the world began.

This time, however, he possesses a powerful system that gives him a massive advantage before disaster strikes.

Knowing exactly how the apocalypse will unfold, he immediately begins preparing for the coming chaos. He stockpiles enormous amounts of supplies, spends vast sums of money constructing an unbreakable safe haven, and continuously strengthens himself through the abilities granted by the system. While society remains unaware of the nightmare approaching, he calmly builds the foundation needed to dominate the new world.

As the apocalypse erupts once again, the people who betrayed and humiliated him in his previous life soon discover that he is no longer the weak and helpless man they once knew. With overwhelming strength, ruthless determination, and memories of the future guiding him, he begins crushing every enemy standing in his way while climbing toward the throne of the apocalypse itself.
