Experience

"Because the yielded attunement from the added unrefined individuality is low, you make very little progress with drawing out the potential of your mind, leaving it weak. Because it is weak, it cannot survive the Squire evolution breakthrough process," Rui explained patiently. "That is why you haven't reached Squire's candidacy."

Prince Raijun was shocked by the revelation. 

He had long grown frustrated with his lack of progress, especially since he had always fostered a deep sense of admiration for Martial Artists.

How could he not? Rather, he never understood why none of his brothers and sisters felt the same way.

Martial Artists were strong!

Martial Masters did not lower their head or chin even in the presence of the Royal Family, barring the Royal Emperor.

Martial Sages bowed to nobody. 

All thanks to their personal power. The power that they themselves had cultivated, belonged to them. That nobody could take from them.
