The Hun family had an ancient inheritance for array formation arts and they were very strong in this field. The Shin family also had an ancient inheritance for talismans. So they were very big targets for regular cultivators and martial artists to join, as having a talisman would be very helpful in saving their life in a bad situation.
The Murong family also had ancient inheritance regarding alchemy, so they were the richest among all the four families. Finally the Gu family had an ancient inheritance for weapon refining and they were the biggest supplier of weapons in this city.
