Mercy. Compassion. Hesitation. Those were the things that doomed the world—and ultimately led to his death. After witnessing humanity collapse during the apocalypse and being betrayed by the weakness of others, he is given an impossible second chance to return before everything falls apart.

But this time, he refuses to make the same mistakes.

Armed with a God-Tier talent unlike anything the world has ever seen, he can instantly evolve ordinary sword techniques into devastating SSS-rank abilities that others would spend years trying to master. While survivors desperately struggle to grow stronger, he rapidly ascends into a monster capable of overwhelming entire battlefields alone.

In a world consumed by chaos, bloodshed, and monsters, people pray for a hero to save them. Yet the man who returned from the future no longer believes in heroism.

What the apocalypse receives instead is an unstoppable force willing to slaughter anything standing in his path.
