If not for other Celestial Marshals of the Path of Adaptation being incompetent, the Path of Adaptation might have already experienced a change in leadership.
—The current situation of the Lord of Scalefeather is actually not much different from the era of the Supreme Heaven.
People in those days transitioned from a primitive state, gradually establishing a political order. From primal strength to authority... even the Giant King himself was not exempt from bias.
The same is true for the Lord of Scalefeather.
After the unique environment brought by Supreme Heaven and the Beast Master ended, the definition of the Path of Adaptation for the new era deviated.
But even the Lord of Scalefeather couldn't just come forward and say "You have misunderstood these professions."
The professions have been born, ultimately how they are understood and used is the business of the Transcendents in the Material Realm.
