Hello LZ, please don't believe the story on the first floor. The quantity of collection is related to the logistics of officers and the time of collection. Then the method is as follows: first, you send your senior logistics officer, preferably above 70, then I usually send more trucks, and then send reconnaissance planes and infantry according to the types of wild jewelry production. If the grassland produces three kinds of precious stones, then you should send three infantry and scouts. Finally, it's time to collect them. I usually collect it every 24 hours or so. Some people say it's good to collect money every two hours, but I haven't tried it. But if it takes 24 hours, it must be collected for more than 24 hours, otherwise sometimes only one or two treasures will be produced.
