Yang Xiao was clearly not just worried about those six Tomb Burial Maps not being entirely in the hands of the seven families He Ru had pointed out; he was concerned that the remaining three Tomb Burial Maps were not all within the grasp of the Li, Zhao, Su, and Chen families.
If that were the case, then he would have to go to extra trouble later on.
He too disliked hassle, and getting the Tomb Burial Maps from the hands of those four families was no simple task to begin with.
If among these four families, there were only one or even two Tomb Burial Maps, with the remaining one or two maps nowhere to be found, where would he go to look for them?
Therefore, having some other clues about the ownership of the Tomb Burial Maps now wasn't a bad thing.
