To be honest, Ning Zheng has never doubted the cruelty of the Immortal Realm.
For the Beast Taming System, sooner or later they have to cultivate "Destiny"; after they become Immortals, they must find an Auspicious Beast of Destiny.
In this regard, that type of beast-taming category is definitely the rarest one.
After all.
The Auspicious Beasts normally born in the Nine-State... amount to nothing more than a single Ancient Bronze Emperor.
The rest of the Auspicious Beasts are basically mixed-blood branches evolved from the Ancient Bronze Emperor as the source, such as Money Child, Golden Turtle and the like.
The bloodline on these fellows has already thinned to the point that it's almost unusable for Destiny.
