This issue really can't be blamed on Ye Weiming for being overly cautious.
Ye Weiming is now a second-rank arrest officer of the Central Plains Court, and his every move represents the image of the Central Plains Court.
His assistance to Virtuous Zen in subduing the demons and monsters of the Thirty-Six Caves and Seventy-Two Islands is indeed from the court's perspective, to ensure this force becomes docile, obedient, and manageable, preventing them from becoming a societal threat.
But it's one thing for the court to personally handle this matter, and quite another to push someone like Virtuous Zen forward.
Having Virtuous Zen as a middleman makes things undoubtedly easier and more acceptable for both parties. Even if issues arise later on, it'll damage Lingjiu Palace's reputation, not the court's.
However, in the process of helping Virtuous Zen subdue these demons and monsters, Ye Weiming must not stand out too prominently, at least not leave a bad impression.
