It's ok to open a shop. If you can earn money, you can collect the blue water dragon, the flowing cloud skirt, the bonzi, the witch judge, etc., all of which are sold at 8W 15W, and you can sell at least more than 20 pieces a day in the store. Do the math, and if one is thrown out for tax, the remaining 20 pieces are 100W. However, it's ok for you to get a number to collect rings and set up a stall, but it's far from the store, because there is only a little space for setting up a stall, and things are not complete. It's best to set up a shop. I just set up a shop, and I have everything. Strengthening makes the most money. One person earns more than 2W, and the average person buys dozens. You can calculate how much it costs, as well as animals and fruits. I used to get a maximum of 600 W a day.
