To Stock up on Goods at the End of the World, I Build a Top-Level Defense Base

Tang Ran experienced six years of apocalyptic killings, but died in an inexplicable explosion. But unexpectedly, she was reborn three months before the apocalypse! Thinking of the family members who died tragically in the apocalypse in the previous life, and the country that tried its best to rescue them Tang Ran secretly made up his mind to stock up on food, write letters, and sharpen his sword. Infected person? Kill! Green tea scum girl? Kill! Traitor? Kill! It's the end of the world, what kind of moral kidnapping is going on? Anyone who blocks my way will go to hell. In her next life, she will do her best to join forces with the country to build a top-level defense base and protect everything she holds dear.
