The Hua Family is a clan that have been thieves for many generations and call themselves the 'Thief God Clan'. They used the clan's secret profound movement art Extreme Mirage Lightning to rob the rich and powerful to help the poor. One of the ancestors infiltrated Sun Moon Divine Hall and stole a Tyrant Profound blade, thus causing the Sacred Ground to hunt the Hua family for several hundred years.
Five years before the Seven Nation Ranking Tournament in the story, the Sun Moon Divine Hall found the family hideout and only Hua Minghai and his wife were able to escape alive. Because of Hua Minghai's eventual friendship with Yun Che, he was able to avenge his family and clan and kill the Divine Hall elder, Ye Xuange, who carried out the massacre.
