It's not that Red Fragrance Alley wouldn't inform Li Deshang, Jia Youcai wouldn't be so naive. He knows that the key to a force like Red Fragrance Alley is to maintain good relations everywhere, and it's impossible to truly bet everything on someone like Li Deshang, one of the 'chief officers'.
Perhaps they might establish friendly relations.
But everyone worth befriending, they would befriend.
Yet, there are differences in importance.
For example, Master Mu before us.
Jia Youcai can speculate, once the owner of Red Fragrance Alley understands the current situation of 'Mountain City', they will definitely strive to please Master Mu with all their might.
A Martial Artist who has achieved 'Bone Tempering' mastery would undoubtedly have significant influence in 'Mountain City'.
However, this is not what concerns Jia Youcai.
What truly worries Jia Youcai is that after all the currying favor, Red Fragrance Alley's attitude might affect Master Mu.
This is not impossible.
