My Mobile Shelter: Surviving the Apocalypse One Solar Panel at a Time

When the world ends, most survivors scramble for weapons and supplies. Ren Yuan? He gets a modification system powered by sunlight. Armed with nothing but an ordinary bus and the patience to wait for his solar batteries to charge, he transforms his ride into a rolling fortress. In this apocalypse, survival isn't about who's the strongest—it's about who can engineer their way through the wasteland. One upgrade at a time, one sunny day at a time.
