Transported to Another World to Become a Lord

All Ellie knows is how to pay to win. One day, she transmigrates into a world of magic and swords, becoming Elena, a noble girl who has just lost her father and brother. She faces relatives trying to seize her title and inheritance, as well as her brother's creditors coming to collect. Ellie: This is so hard. I don't know how to play a game where I can't pay to win. Luckily, Ellie's game System comes with her. It doesn't have AI, and her max-level account has dropped to level 20, but at least it's a cheat ability. Ellie: I think I can do this after all. The mage recipes are ready-made. Mix up a potion and drink it to level up. The mage skills are ready-made. One Invitation from the Dead sends you straight to reincarnation. The cooking recipes are ready-made, and so are the cooks. Opening a restaurant is easy. The farming techniques are ready-made, and fragrant spices sell across the continent. The pharmaceutical techniques are ready-made, and customers line up outside the pharmacy. With her new wealth, she buys land and people, raises her noble rank, and Elena happily swaps her coronet for a new one. While wars rage across the world and the fighting gets brutal, great landowner Elena watches the endless golden waves of wheat and thinks, Ah, what a peaceful life. [A heroine who loves earning and spending money x a hero who loves saving and hoarding it] My next story, The Rich Heiress Just Wants to Make Money, is now underway. It's about Elena returning to Earth. Second blurb draft: Second blurb draft: The entertainment industry is constantly in flux, with stars fighting over the top spot. Fans are just as passionate, battling for the love of their favorite idols. As an agent, Elena has to put up with her own celebrity's fans insulting her every day. "Why are you taking so many jobs? Are you trying to work my Lunlun to death?" "Bloodsucking agent! Lunlun should have gotten a new agent ages ago." "The agent deliberately takes bad jobs. She's been exposed!" Elena grabs "my Lunlun" by the tie and gives it a sharp tug. "The fans run up a debt, the idol pays it. Have you decided how you want to die today?" Leonard: "As long as you're happy, go ahead." When Leonard announces their relationship to the public, his fans, who used to enjoy watching other celebrities' careers crash and burn, are struck down on the spot. "No, Lunlun, look carefully! She's a vampire! She's tricking you! She only wants your money!" "MMP, Elena the Devil, you're not worthy! You're shameless!" "Like this if you hope they break up tomorrow." "Lunlun, if you don't break up with her, I'll jump off a building!" Elena happily scrolls through the internet. Mm, his fans are as energetic as ever today. Leonard cheerfully picks out rings. "Which one do you think looks better?" The two are having the time of their lives in the entertainment industry when one day they suddenly remember what they originally came for. Right, they'd crossed the barriers between worlds to get revenge, or, more precisely, to avenge Elena. But how did they end up forgetting? Elena waves her hand. All right, let's adjust the schedule and get the revenge side quest done quickly, without delaying the main quest of making money. Leonard: "You're right. Making money is the most important thing." First blurb draft: As Elena drinks an ascension potion and attempts to reach demigod rank, the space-time continuum twists. Elena is transported back to the real world, where she'd once had terrible luck. But that world is just a book, and she's the villainess destined to be cannon fodder. The heroine in the author's story is a wealthy heiress, the lucky darling of everyone, sweet and adorable. The hero is a celebrated genius, the finest among a circle of heirs, and falls for the heroine at first sight. Elena, the villainess, likes the hero and targets the heroine. When her schemes are eventually exposed, she's kicked out of the house and dies in poverty by suicide. Elena: What idiot used my face to do something this idiotic? It's time to settle old and new scores. The lucky darling of everyone? Ha. Of course she's blessed when she's been stealing other people's luck. Give their good fortune back. Sweet, adorable, gentle, and considerate? Ha. Let's see how adorable she is once she no longer has that overwhelming good fortune. And the hero, the celebrated genius? Wait, why is he looking at me like that? Her fiance, who came with her: Kid, draw your sword and face me in a duel! Elena pushes him aside. Don't waste your time. Go be a celebrity and make money. (Elena was originally from the world of the book. She transmigrated to a world of magic, reached max level there, and then returned to her original world.) Theme: Managing an estate
