Ordinarily, the positions of the Four Great Divine Constables should be nominated by members of the Six Gates, just as it was with Su Xin before.
However, the adoption of this model back then was because Tie Ao wanted to maintain the absolute justice of the Six Gates.
But now, even if Tie Zhan randomly appointed someone to be one of the Four Great Divine Constables, who would dare to utter a word of objection?
Therefore, Tie Zhan had long been prepared to discard the old system altogether.
At the moment, Tie Zhan had summoned Su Xin because he wanted him to recommend a candidate for the Four Great Divine Constables.
In fact, if Tie Zhan wanted to fill both positions with members of his own Iron Family, he could, but that wouldn't sound so good if word got out.
