The Consummate realm cultivators left the place without doing anything. The victim is Sravan and he is in no state to fight back or even talk for that matter.
As for his next to kin, Sai. He doesn't want to pursue the matter any further.
So, they decided to just make a move.
They have a lot to do with the war. They have to deal with the aftermath and the first thing they have to do is eliminate all the traces of the church, including the left-over followers, the priests and high priests, their traces in the subordinate empires, everything.
Apart from that, they have to create new governments and authorities. They have to establish the chain of command, repair the damage caused by the church, and deal with a lot of things.
This will take months to complete.
