The Ancestral Dragon was a powerful bloodline in the Immortals' World, exceeding the Four Sacred Beast Kings among the Four Sacred Beast Clans. According to Mo Tianyun, Sacredfeathered Tiger Emperor's bloodline is comparable to Ancestral Dragon's bloodline.[1] But in Wind Venerable's perspective, Ancestral Dragon's bloodline is one order higher than Sacredfeathered Tiger Emperor's bloodline.[2]
The Ancestral Dragon bloodline vanished several billions of years ago. No ordinary person can learn about them, but anyone who does know about them is definitely an apex expert who has survived countless years or someone important with a great background.
