Trading System: Somehow, I Became a Pillar of the Nation

[Not sure if there's a CP yet, so ship whoever you like! (A beloved-by-all story, meaning everyone dotes on the protagonist) + can transmigrate to other worlds + plot-focused, ensemble cast + pure wish fulfillment!!] All Lu Chi wanted was to run the family orchard, keep a few dogs, and enjoy a happy single life. Who could have guessed she'd get bound to a System, and a trading System at that? Her very first trading partner turns out to be an anti-Japanese hero from the Republican era! Lu Chi, who'd been pretty indifferent to the System, instantly perks up. Chinese people have an instinctive hatred of Japanese invaders. She doesn't care if the time or place is wrong. If it's about fighting the Japanese, she's ready to jump right in! But as she gets involved, Lu Chi realizes she's not quite up to the task. After thinking it over for just a second, she turns around and hops aboard a big ship, ready to enjoy an easy ride to victory. Sometimes, all it takes is a little shamelessness and finding someone powerful to back you. Isn't that the recipe for a wonderful life? She only meant to be a couch potato, so how did she end up as the ultimate couch-potato queen, clad in armor, fighting across other worlds and bringing back the spoils of war? Looking at her spoils and the smiling faces of her fellow countrymen, some stern, some kind, some handsome, some beautiful, Lu Chi shrugs. Sometimes even a couch potato needs to roll over now and then. Doing something good for your country and fellow citizens isn't so bad, is it?
