In the Rancho Monogatari Ore Town, companions can earn money in the following ways: 1. Production of products: partners can grow various crops and process them into products after harvesting. These products, including bread, biscuits, milk, etc., could be sold in the market to earn some profit. 2. Capture insects and animals: The companions can capture insects and animals such as frogs and birds near the town and sell them to the animal shop. These animals could be used to make dishes or as medicinal herbs, and they also had a certain market value. 3. Working part-time: The companions can work in the town's restaurants, shops, or farms to earn some extra income. 4. Collect items: The companions can collect various items such as gold coins, copper coins, shells, etc. in the town and sell them to merchants. These items could earn a certain amount of profit, but they required the companions to put in a certain amount of effort and time. However, due to the relatively high prices in the ore town, the partners could not buy a large number of chickens and cattle to produce products, so they had to make money through other means. Although growing sweet potatoes was not profitable, it could provide food and could be used as a temporary residence for his companions when exploring the town.
