Blue Song Flower: The sacred flower of the Ice Tribe - similar to a rose, each flower has only 9 leaves, the petals are white, and the center of the flower has 3 dark blue petals. The white petals are highly poisonous, and the dark blue petals can cure it.
The blue flower likes shade and grows in the cold Hansheng Lake. The flower blooms in the last month of every year in the Ice World. The flowering period does not exceed 13 days and only blooms on moonlit nights.
On the first day when the Blue Yin Flower blooms, it will make a light and distant sound, as if there are thousands of fairies dancing around the gods, just like the sounds of nature, hence the name - Blue Yin Flower.
