Cross-Time Supermarket Tycoon

Xu Shu is a shop owner on the brink of ruin when an accidental glitch opens a doorway into an ancient kingdom gripped by famine. Through that passage, she begins bringing modern goods back in time and trading them with the people who have nothing to eat. Her small store is suddenly the most valuable place she has ever known, but every sack of supplies she sells draws attention from powerful figures at court who want to know where it comes from.
