A sect, if it loses its mastery, it is equivalent to losing the foundation it relies on for survival. The mastery of Dazhu Temple is precisely the two divine skills recorded in the Secret Manual in Jiang Xiaobai's hands.
It is not difficult to find some little monks to chant sutras and practice Buddhism for Dazhu Temple, nor is it difficult to train them, it just requires some effort. The difficult part is to fathom those two sets of mastery and then pass them down.
Both of these divine skills are top-tier in the world, capable of causing a bloody storm in the martial arts world. Jiang Xiaobai doesn't understand Buddhist Law, he could initially take the Secret Manual to someone who does understand for a look, but he dares not do so. Who can guarantee that upon seeing such divine skills, one wouldn't develop malicious intent?
