You can spend 500 gold coins to buy the wedding ring formula on the travel van that appears in the north and west of the coal mine forest every Friday and Sunday. The formula material includes 5 iridium ingots and 1 multicolored fragments. After purchasing the formula, players can synthesize these materials in the forging factory and get the wedding ring.
Wedding rings are used to propose to other players in multiplayer mode. After the successful proposal, the two parties entered an engagement state, and then the wedding was held within three days. However, it should be noted that in the single-player game, players do not need to make wedding rings to complete the wedding events in the game, but interact with the selected NPC by increasing their goodwill, which directly triggers the marriage proposal and wedding story.
