When the Apocalypse Came, I Hid in a Parking Garage Shelter

The setting is very comfortable, and it feels like it combines some settings of the fallout shelter with local elements. The protagonist has a brain, and does he buy various things and collect supplies at the beginning like other natural disasters? The subsequent items are all made by the protagonist bit by bit. Although there is a system, the sense of existence is very low. It is more similar to a shelter data management and information analysis planning system. The exchangeable items are basically blueprints, and you have to find the materials yourself. It is a rare masterpiece.

This apocalyptic setting is very good, you can read it

Good apocalyptic writing

It's a post-apocalyptic article about joining a group to keep warm. It's pretty good.
