The "one hidden, two wealthy families, and three sisters" mentioned in the incantation referred to different stall owners.
Among them, the Three Sisters were mysterious cultivators who often appeared in the female cultivators 'area. Their stalls often had some beauty pills and other medicinal pills that female cultivators were after.
As for the two rich families, they would appear from time to time in the treasure-hunting area. They were rich, but their two unfilial children would spend their time and drink to obtain spiritual stones. They would steal their family's treasures and sell them in exchange for spiritual stones.
As a result, these two wealthy families were deeply loved by ordinary cultivators. Many cultivators had brought large amounts of spiritual stones with them, waiting for the appearance of these two wealthy families!
