Star: Foreseeing the End, I Dug a Bunker with My Bare Hands

It has been ten years since 3I/ATLAS arrived on Blue Star, hanging high in the sky. Experts say the problem is not big, just like having an extra moon. Except for a few changes, such as human beings need to stay up day and night, and their work and rest are reversed. Where the cows and horses are, they are not cows and horses, and it does not affect my takeaway business at all. Until I found out the end was coming... Enough talking, I have to build my bunker.
