Not all forces are qualified to establish a Daozi.
Even the forces of the Divine Monarchs in the Heavenly Court dare not have their successors call themselves Daozi.
Only those with a dao lineage at the pinnacle of the Immortal World, like the Heavenly Court or the Three Great Saints, have this qualification.
Among the Demon Clan, only those of Demon Emperor bloodlines, and those of the Dragon Clan, Qilin Clan, Phoenix Clan, etc., are qualified to establish a Daozi.
Each Daozi is the hope of inheritance for that lineage.
One can imagine how high this status is.
The Heavenly Dragon Mountain Master was equally shocked, although he knew Su Yu had extraordinary talent, he brought him this time to appear in front of the Infinite Palace Master and leave an impression, to compete for the position of Daozi of the Infinite Immortal Palace in the future.
However, he did not expect his master to have such boldness.
