How to maximize the value of commodities?

Here, let me give you an example: tap water should be your long-term commodity, right When cooking at noon, you carry a basin of water to wash rice. After washing, you can use this basin of water to wash vegetables. After washing vegetables, this basin of water has become turbid, and broken rice grains, rotten vegetable leaves and soil are deposited on the dishes below. At this time, you can fish out the rotten leaves and feed them to the chickens, precipitate the broken rice grains and soil, pour this little mud into the vegetable field as fertilizer, and the last pot of water can also be used to flush the toilet. Of course, you should try to flush it several times.
