I Took My Pocket Dimension to Primitive Society

[Transmigration]+ [Spatial storage]+ [Stockpiling supplies] [Primitive continent] Qi Yu has a family heirloom bracelet that even junk-picking grannies look down on. It unexpectedly unlocks a pocket dimension. According to the novels, that means either the apocalypse or transmigration, so she starts stockpiling supplies. It turns out she really has transmigrated, but the novels never said what to do if you transmigrate to prehistoric times! What, there’s a rainy season with two straight months of rain? And a cold season with temperatures below minus ten degrees? All I want is to lie low and survive. And maybe teach the primitive people to clear land and farm, and raise livestock. P.S. This is a fictional setting!!!
