How to play the five elements?

Wanghuo and water mirror are about 4-5W. Go to Xingxiu and Yanggu to do it yourself. Nobody usually buys it. The winning wood is generally 1-2W, thick soil is 7-9W, and pure gold is 3-4W. One of these five materials can be combined into a five-element combination. Then on Sunday, I went to the Luodao Taoist Temple for a mission. After defeating the little demon, the combination turned into crystal and obtained excellent equipment.
