You spend gold coins to buy alchemy materials from the alchemy furnace, camellia 1500, pipa 5W, value 1 reiki = 10 gold coins.
Basically, you spend 5w on an alchemist. If you win, you will get 50 pieces of Yinshadan =50W, with * * * bits 12.
This thing is so strange. I suggest not to play. Netease collects gold coins, just like opening a treasure chest.
I once lost 500W at once and bought that. The more I bought, the bigger it became, but he just missed it.
