In every major city, there is a notary who does the business of colorful jade. He consigns it there, sells it cheaply and can buy it soon. After people buy it, the system will send you an email. (As long as someone buys it, you will be prompted), and then you can find NPC and collect game coins from consignment, and your colorful jade will become gold coins. You can also buy some things to sell on the shelves, such as Tian Tong Keyes and Xuan Shi. Others are not recommended. Hope to adopt, thank you.
