Who Are They in Xiuxian?

My name is Yanyu, and I am a Supreme Elder of the Five Elements Sect in the Tianling Domain. I feel very strange that an outer disciple has nothing to do all day long and does not practice cultivation. He only talks about some incomprehensible nonsense. But his cultivation has improved rapidly, and his skills are not owned by our sect. I don't know why, but every time I'm with him, as long as I show some amazement, I feel my cultivation is decreasing, but when I check afterwards, nothing decreases. It must be my misunderstanding, I actually felt a strange aura on his body... Ps: This book mainly adopts the first-person perspective. The protagonist has no system and no harem.
