Apocalypse: Help! I'm Broke from the Start

(Apocalypse + reborn + no System + no pocket dimension + stockpiling supplies + building a base and a faction + race war + decisive and ruthless + sci-fi + romance) When the apocalypse arrives, a particle storm caused by a supernova sweeps across the globe. Overnight, the world's power grids are paralyzed and electronic devices are destroyed. The zombie virus breaks loose and spreads unchecked. Human civilization begins its countdown to extinction. Wang Chi, who struggled to survive for four years in the apocalypse, is reborn two weeks before it begins. He has no money, no pocket-dimension ability, and is only a driver. A crisis right from the start: how can he get by with no money? With just one starting point, the protagonist builds the apocalypse's strongest shelter: a research institute and a refuge city! He explores hidden realms, slays zombies, and uncovers the secrets behind the apocalypse.
