Don't Panic When the Apocalypse Arrives: Stock Food First, Then Guns

Jiang You never dreamed she would survive the claws of zombies only to be betrayed by the very family she protected.
Years later, she destroyed the experimental facility that imprisoned her.
Those who sold her out? Dead!
The base that betrayed her? Obliterated!
Who waits for the next life to settle their scores?

With her revenge complete, Jiang You exhausted her powers and self-detonated, but unexpectedly, she was reborn-half a month before the apocalypse broke out!
This time, she vowed to take back everything that was hers...

Stock up on food first, guns later-when the apocalypse comes, stay calm.
But just as she was ready to live quietly and hoard supplies forever, a tiny bottle cap fell from the sky. That's when she learned her world was actually a book, and she was the villain who tragically died in the story?
If that's the case, don't blame her for being ruthless!
Sacrifice the heroine, unleash unlimited power!
...
When zombies erupted, other survivors were frantically fleeing.
Jiang You: "Hey, zombie up front, wait a second. Is that brain of yours ripe yet?"
While other survivors fought tooth and nail over scraps of food:
Jiang You: "Hotpot, BBQ, river snail rice noodles, roast duck, fried chicken, or Buddha Jumps Over the Wall... What should I eat today?"
When other survivors tried to use moral blackmail:
Jiang You: "Sorry, I don't have morals. You can't blackmail me."
