The pendant refers to Zhao Shiran.
Elder Zhao is a typical short-sighted person. He turns a blind eye to Lu Bei's numerous flaws, selectively magnifies the few redeeming qualities, and stubbornly sticks to his own reasons. Any advice you offer would fall on deaf ears.
At this moment, Elder Zhao is having a lecture with the Grand Tutor.
Because Lu Bei disagreed, Zhao Shiran refused to become a disciple. But when facing the Grand Tutor's invitation to attend his lecture, she couldn't bring herself to refuse and decided to freeload.
As for cultivation, Lu Bei solely relies on his own aptitude. Be it bottlenecks or bottle caps, everything withers in front of billions of talents.
When he instructs Zhao Shiran, he uses all sorts of violent methods, charging headfirst without regard.
