The Director having such thoughts is quite normal, after all, it seems that aside from Immortals, no other cultivator is quite up to the task of maintaining order.
It's known that although the Three Pure Temple hosts many powerful beings, some of whom are just a step away from facing their Tribulation, the Three Pure Realms are vast, and naturally, they won't lack talented and extraordinary individuals. Who knows if there might be some reclusive powerhouse with a grudge against either the Three Pure Temple or the Law Enforcement Bureau that might emerge and potentially cause significant conflict.
But it's different for an Immortal, after Becoming Immortal, they automatically ascend to the Immortal Realm, no longer residing in the mortal world. In other words, if one could invite an Immortal down from Mount Kunlun, that would definitely be a top-tier fighting force.
