To say that the hierarchical structure of the cultivation world is determined solely by aptitude might be somewhat biased.
But for some things, it indeed all depends on aptitude.
For instance, the above matters represent the limits that the disciples of various levels within the Yin-Yang Sect can accept.
"Wha, what is going on?"
"If, if my intelligence hasn't failed me, then Junior Brother Nameless is the so, so-called little Grandmaster that the deputy Palace Master of the Outer Heaven Palace spoke of?"
"Isn't he an outer sect disciple, without even a master? How, how did he become a little Grandmaster?"
"Zuo Zhuang, you're the most familiar with Junior Brother Nameless, do you know?"
"I don't know, but, but I can somewhat understand why Brother Huo Mang would bow so deep, deep to me... oh no, to him before coming."
...
The above is the limit of what outer and inner disciples of the Yin-Yang Sect can accept.
