One should know that there are many types of disciples, including registered disciples, ordinary disciples, direct disciples, closed-door disciples, and so on.
Likewise, when Zhan Yun and Baili Xuewei had agreed that Zhan Yun would exchange elixirs for cultivation techniques, An'an could be considered Baili Xuewei's registered disciple.
As for ordinary disciples, this kind of relationship is much better.
Ordinary disciples don't need to pay tuition to their master, who in turn imparts some basic cultivation techniques, or teaches a certain type of cultivation technique to the ordinary disciples, who are responsible for spreading the sect's teachings far and wide.
Generally speaking, the relationship between an ordinary disciple and their master is already considered quite good.
Initially, in Zhan Yun's mind, if An'an could become Baili Xuewei's ordinary disciple, that would be cause for great joy, as it would mean learning many genuinely useful things.
