Even in such times, in recent years, the South Sea King Ling had invaded, with Mo Zhu Mountain and Emei facing the confrontation, while Divine Teachings made a significant incursion into the Central Plains, spearheaded again by Emei. Previously, when Hu Lu Shanyu moved south, if it hadn't been for a slight error at the beginning, Emei would also likely have had to step in to address it.
As they say, "As above, so below." Naturally among the disciples of Emei, there are characters like Canglong and Yang Nanying, but since most of the disciples who were taught are upstanding heroes, demon-slayers, and champions of justice, it's unlikely that the three venerable leaders of Emei would really be all that bad.
So it seems, this old man is probably that type, just that type—simple and pure.
A partner of justice.
