LB1 also gets the bonus benefit of being the "revelatory" chapter in this regard. I do think though that it's not so much that they avoid going as hard on it in later chapters because of how much weight was placed on it in LB1, but rather that it's almost necessary for them to not put too much focus on it all the time because when we know we have to go through like 12+ chapters, it gets repetitive and loses its impact. Bringing it up to the same extent every chapter would have only worked well, I think, if we also got closer characterization of gudao and Mashu in that regard, but that doesn't get as big a focus as it probably should, so this is what we're left with.
