My Shop Came with Me to the Ancient World, but the Heir Won't Stop Flirting with Me

[Historical romance + ancient-era fantasy + System + modern woman transmigrates to ancient times + love grows over time + farming] (A wild imagination, an upgradable System, and one golden finger after another along the way!) Gu Yue, an agricultural science graduate, runs a shop selling seeds and seedlings. After being bound to System 009, she begins her life in ancient times. * [Ancient times: After three consecutive years of severe drought, several heavy rains finally fall, but when planting season arrives, there isn’t a single seed to be found! Everyone is miserable. Don’t worry, Yueyue’s Seed and Seedling Shop has whatever you need, and plenty of it! Goodness, there are so few crops here. Sweet potatoes and potatoes yield so much per acre, so let’s plant them! And let’s grow all kinds of fruit trees...] * [Gu Yue: What? You need a hundred jin of seed grain for one mu of land? How on earth did you manage that? Let me teach you how to farm! At harvest time, one person cries out: My family has loofah, green beans, cucumbers, eggplants... Another says: My paddy yielded 1,200 jin per mu!] * [County magistrate, don’t you have official business to attend to? What? You want to discuss farming with me? I’m just a shopkeeper! That’ll cost extra! Before long, the county magistrate transforms into the Marquis Yan, the man all the noble young ladies in the capital are clamoring for. Tsk, tsk! Ladies, open your eyes. Don’t be fooled by that face of his! What? You want to discuss our marriage? Have you misunderstood what we are to each other? Do you remember that day, in that year and month, when you held your sword to my neck?!] * [What? I’m actually an ancient person?! I can’t believe it! Most importantly, what about my ten-million-dollar reward from the modern world? No, twenty million! 009, explain yourself!
