Son-in-Law from the Start: My Winning-by-Doing-Nothing Act Is a Little Off

[Transmigrate into a live-in son-in-law? This hellish script is locked in!] Overworked office drone Lin Xiaofan dies suddenly after pulling an all-nighter. When he opens his eyes, he's become the notorious useless live-in son-in-law of the Su family in the Great Jing Dynasty. He lives in a woodshed, gets fed to the fleas, and has a divorce notice slapped in his face by his icy wife. His hatred meter is maxed out from the start! [To put food on the table, I'm forced to max out my outrageous schemes] He became a live-in son-in-law just to get a meal? His mother-in-law makes things difficult, the housekeeper is spiteful, and creditors are pounding on the door... With death on the street staring him in the face, Lin Xiaofan snaps! **Pork stir-fried with chili peppers sparks a kitchen revolution, the multiplication table from one to nine leaves the bookkeeper speechless, and plastic sheeting saves the grain in a torrential downpour. Using modern knowledge to exploit loopholes in ancient times, he keeps turning “dominating the business world” into “making the whole city laugh itself silly,” and “heroically saving a beauty” into “blowing up a manure pit and accidentally injuring his father-in-law”... [We agreed I'd coast to victory, so why is my icy wife actually warming up to me?] When Su Qingxue discovers that this “crazy son-in-law” can knock out assassins with “anti-wolf pepper spray” while muttering, “KPI targets are why I transmigrated,” she falls into deep thought: Should I... still tear up the divorce notice? “My lady! I really didn't mean to turn my life around! They forced me to put on a show!” “Shut up and finish drawing the toilet blueprints.”
