My Apocalypse Space Led Me to the 70s

Si Ningning was tormented by chilling nightmares: a zombie apocalypse, her gruesome end. Convinced it was prophecy, she frantically activated her ancestral jade pendant, revealing an infinite personal dimension – the perfect fortress to hoard every imaginable supply. She poured her vast family fortune into stockpiling enough food, water, and necessities to outlast any doomsday. But the apocalypse never came. Instead, she woke up in the stark, resource-scarce 1970s. Her massive modern-day stockpile, meant for fighting hordes of undead, now makes her the wealthiest woman in an era where even a single grain of rice is precious. Can Si Ningning navigate this unfamiliar past, armed with an absurdly overpowered advantage, or will her golden finger become her biggest secret to protect?
