I Have an Armored RV

A week before the apocalypse, Zhang Yi received a system notification.

Hoarding supplies?

Go to a small shop?

Empty the supermarket?

I’m sorry, but I bought seven warehouses of supplies in advance!

Build a fallout shelter?

Hide in the basement?

Sorry, I have an armored RV. It’s safe and comfortable, and it can even be upgraded!
