Depending on translation they are also known as the Lanfu Clan. The surname Lanfu = Blue Talisman
The Blue Talisman Clan hails from the Nine Souls Galaxy and have a certain level of status there unlike the Ancestral Martial Starfield. They have various envoys in many starfield that oversee the extraction of a specific blue ore that they use to cultivate. The amount of supervision assigned to each starfield is dependent on the quality of the blue ore. In the Ancestral Martial Starfield, the blue ore found there is of inferior quality so only two members are stationed there, Lanfu Jianpeng and Lanfu Longping. They were the hidden backing of the Wuming Clan and the reason they were able to reign over the Ancestral Martial Starfield even though they were technically not the strongest existence there.
They are said to be unrivalled in the entire Holy Light Galaxy, with the Holy Light Clan being the only power able to contend with them. However, it is later revealed that their power pales in comparison to Chu Xuanyuan, who they learn single-handedly exterminated their ally, the Bloodline Granting Heavenly Sect with Old Ape.
