Global Apocalypse: From the Start, I Stockpile Billions of Supplies

[Apocalypse + zombies + reborn + stockpiling supplies + no saintly do-gooder + building a faction] Chen Xia was reborn with his memories intact a few days before the apocalypse arrived. Knowing everything in advance, he poured every last bit of his wealth into stockpiling survival supplies! In his previous life, he died alone in misery. This time, all he wants is to survive with his wife! (This is not an ordinary apocalypse, not an ordinary apocalypse, not an ordinary apocalypse. The important things bear repeating three times.)
