At the End of the World, I Came Back with My Whole Family

There is a 180-day countdown to the sudden death of the sun, and the whole family and their close friends are reborn together before the apocalypse. Dismantle the fighter planes and cast shields, and use the molten starships to repair the sky! Folks hoard goods and build fortresses, while state secrets fly into the stars. This time, we not only have to survive the eternal night, but also for hundreds of millions of compatriots... To hold on to the last fire of civilization! (The fungus picking season is here, so I'll stop updating for the time being. Come back when you're interested, hehe)
