How can I get the five-element beads in Zhu Xian 2?

Hello, five-element beads: Golden wood fire, water and earth all need five-element beads. Five elements of beads can be exchanged for the narrow learning task of Four Treasures of the Study. Four treasures will randomly give you two five-element beads for each learning task, which are made in pairs (gold beads for spiritual divination, earth beads for tourism divination, wooden beads for intuitive divination, and water drops for petal divination), and a five-element bead will be randomly given for each dream task. These methods can't be used in the previous lottery.
