The Supreme Naga's ascension to Asura Naga was most visibly marked by a sudden increase in appetite, as well as a surge in the Power of Faith provided.
Originally, the Power of Faith provided by the Supreme Naga was slightly less than that of Humans, but now, after ascending, whether in terms of strength or species hierarchy, they have surpassed Humans, and the Power of Faith provided has skyrocketed, reaching about twenty times that of Humans.
In other words, a True Believer who previously could only provide just under one point of Power of Faith could now provide about twenty points.
However, they still can't compare to Dragons. Even now, as merely a casual believer, Black Dragon Nejelanmu, who follows Lin Xiao, provides several hundred times the Power of Faith of Humans, which is more than ten times that of Asura Nagas.
From this, it is clear that there is still a significant difference between Asura Nagas and the Dragon Clan.
