What does it mean for members to buy souls?

The soul is there, that is, to get what you want once. Members buy some products such as blessing bags, which means they get the blessing bags they want.

Once in the soul, it has more meaning on the internet. Playing BOSS once will drop rare equipment or mission items with low explosion rate. Wash talents. Wash the rarest talents at once. Single draw limits SSR/UR, or draw rare items once. The skill game won the highest evaluation reward.
