The Immortal Clan was established starting with the entry on the Dao of the Gou.

Jiang Yun transmigrated to the world of cultivation, becoming a tenant farmer in the Yu Kingdom. After marrying, he activated the family's cultivation affix system. By developing his family and unlocking achievements, he could obtain various affixes and rewards. Marrying and starting a family—he obtained the affix "Eternal Sixth," rewarding him with immortal bones. Having children—he obtained the affix "Living Blessed Star," rewarding him with cultivation methods. "Living Blessed Star": Brings good fortune and averts misfortune, bestowing luck upon oneself and blessings upon descendants. "Turning Stone into Gold": Grants mortals spiritual roots, enabling them to possess the aptitude for cultivation. "Hoping for a Dragon Among Sons": Grants you a special physique, and there is a chance that your descendants will awaken the same physique. ...Initially, the Jiang family was just a family of three. Under Jiang Yun's leadership, they rose from humble beginnings to eventually become an immortal immortal clan that shook the myriad realms.
