Liu Qingfeng took out some data:

"Currently in the Sea Dragon Starfield, a total of 13 billion crystals have been obtained, which is almost the same. There are not too many crystals in circulation in the Sea Dragon Starfield. At present, there are materials worth nearly 500 billion crystals, which must be sent to other star fields for further processing. Trade, but at a discounted price."

"Most of them are the income of the immigrant population of various planets, the construction of cities and other project expenditures. Currently, it is about five billion crystals."
