Cloud Crystal Mist Flow

The cloud mist would condense into a flow of water and gather in the cloud river. Every decade, a cold flow would come. When the coldness invaded the cloud river, it would form the Cloud Crystal Mist Flow. The little ball of cloud mist inside these ice crystals are the purest of cloud essence and is something great for forging. These ice crystals were each the size of an egg and were rhomboid. It was clear and transparent, and there was a small ball of cloud mist which slowly flowed inside each rhombus.
