Holy Hall does not follow the master-apprentice system; only those samurai with exceptional talent might have the chance to be taken as disciples by strong individuals.
This master-apprentice relationship is not part of the Holy Hall system. It is entirely a private relationship.
At Yanzi's age, she is only a fifth-level Paladin. Her talent can only be considered reasonable. She does not have her own teacher.
However, after getting familiar with Yuan Ping'an in these few days, Yanzi's sweet words managed to charm others, which led her to call Yuan Ping'an a teacher.
Unfortunately, Yanzi's effort was wasted. Wei Ying and Yao Peng did not understand the subtle differences of that address or the internal dynamics of the Holy Hall.
Gao Xuan could sense some of Yanzi's boasting, but given his situation, he couldn't play along.
Yanzi was ultimately still a teenage girl; although she didn't succeed in boasting, she didn't really mind.
