One of the most basic ways to make Korona (money) in this game but assuming that other people just like me who didn’t know about this and did runs of enemies just for 4k korona only to be in negative balance again in like 10 min. This guide will help you make (hopefully) a lot of Korona super fast.
After a few runs and gathering materials like wood, stone and metal etc etc, go to the storage/shed right to the left side as soon as you leave you house and transfer all of your materials that you have a 100+ of, would usually go for 10k korona all together.
That board right in front the house that has a small on map of your farm on the top left side, yeah that one. Once you interact with it, click on the anchor sign on your farm map as shown in the picture attached.
Assign 4 monsters to move your materials from shed/storage to the docks and sell them.
You can sleep in your bed back to back to make this whole process go by faster as it will take a little bit of the in-game time.
Side Note: look our for your monsters food, you may be sleeping over and over to pass the in-game faster but if any of them run low on food, they’ll leave the duty assigned to them.
