Legend has it that since ancient times there has been a kind of supernatural being called "hermaphrodites", who are born with unpredictable abilities. Today, there are only four such people left. They gather in the west family of the spirit-killing family. The eldest Xi Luo knows ice and fire magic; the second west Yin can go to heaven and earth; and the third west Hao has infinite power. And the younger brother Xixian, a boy with cat eyes, has an unknown side.
