The apocalypse arrives, and a four-member female group is driven to a desperate situation by a horde of zombies, yet they all experience collective rebirth at the moment of life and death. Returning to before the disaster, they awaken space, stockpile supplies, and build fortresses, solely to rewrite everyone's fate. But fate is far more bizarre than the apocalypse, and step by step they walk into a turbulent troubled world, transforming from survivors into those who wield the sabers, gathering compatriots, building armies, and taking back everything that was plundered. The four of them, who were once driven to a dead end, this time not only want to survive, but even more so, to hold their sabers and protect the rivers and mountains behind them.
