After becoming a Guardian, Mr. Su Bai actually gained a deeper understanding of the Land of Enlightenment. One can seek enlightenment without it, such as Chen Ru and Yan Huihong; they achieved enlightenment even when the Land of Enlightenment was sealed, with no effect at all.
It's somewhat like an official ritual. Broadcasting drives this form of formalism with its authority and characteristics, turning it into a norm that all audiences must adhere to, passed down imperceptibly through generations as a ritual everyone follows.
But in reality, the Land of Enlightenment serves no real purpose; it's merely a collection room for broadcasting.
