After struggling in the apocalypse for ten years, Yao Ran died and returned to the three months before everything began. She returns with hatred and thirsts for revenge, intent on making those who owe her pay with their lives.

With her grandfather's inheritance, Yao Ran sold everything and frantically hoarded weapons, medicine, food, and supplies. She sharpened her sword, stockpiled up supplies, settled scores with scoundrels and villains, and repaid them with both enmity and kindness.

When disaster strikes, she begins her revenge, facing a dangerous world, and is determined to outlast her previous life.
