I recently started a new save to try the slime race, everything has gone smoothly in the early game for earning money. My main ways to earn money so far have been selling soils, selling bonito and sugar wines, placing high value in town, setting up automatic mushroom wine shop with restaurant + premium store policy, and selling gears from nefia that I don't need.

However, as the game progresses, I’m unsure on how to increase my profits. Right now, my biggest income source is sugar wine and bonito wine, which usually gets me around 20k–40k. In my previous save file that I have over 3000 days, with average nefia level ~400 and void level ~150, my highest profits only reached about 50k–100k.

Is there a more effective method, farm setup, or investment I can use to generate higher passive income and more reliable active income in the mid-to-late game?
