My Restaurant Connects Worlds, and I Successfully Serve My Country

Traveling across countless worlds + buying low and selling high + handing everything over to the authorities The poor girl has gone unpaid for six months by her heartless boss. She can't afford rent and is about to be kicked out by her landlord. Just as she's preparing to fight back using the law, her boss runs off and leaves her the noodle shop! With no other choice, Jiang Ran takes over the Hao Zai Lai Noodle Shop. On her first day running it, something feels off. Why are her customers cosplaying in ancient costumes? And why are they savoring a bowl of plain noodles in water? Then, when they can't pay, they give her a chipped old porcelain bowl. Oh well. She's just getting started, so she might as well do a few good deeds and build up some good karma! On the second day, the customers come back, this time with two children! One person eating for free wasn't enough, so now the whole family is joining in? But when it comes time to pay, the kind customers give her two silver ingots! For three bowls of noodles! They're worth two whole silver ingots! She takes the chipped bowl to a pawnshop and discovers it sells for a fortune. The silver ingots are valuable too! She's hit the jackpot! On the third day, the customers bring even more people. After eating, they give her ten taels of gold! A few bowls of noodles have earned her real gold and silver! The landlord won't let her stay? She'll just buy the place! These people from another world aren't just ancient folk. They're her benefactors, plain and simple! And so Jiang Ran begins buying low and selling high. Instant noodles and ham sausage, costing five yuan, sell in her shop for just five taels of silver! Pre-made spicy hot pot with a handful of fresh vegetables, costing ten yuan, sells in her shop for just two taels of silver! The customers all give it a glowing review: “Immortal Jiang, what recipe is this? It's so delicious! I have to take it to the Emperor!” Jiang Ran says nothing, and simply keeps searching for convenient, quick-to-prepare pre-made dishes with sky-high profit margins...
