Zhang Yi had discovered that the enemies were from some sects of the Divine Sanctuary of the Beasts who were dissatisfied with their leaders' decision and allied themselves with the organization of the soul eaters to destroy the divine plane.
Only from what Zhang Yi read of the Divine Realm elders' memories can he see the danger that the divine plane was facing, if the great sects could not organize things properly, it was quite possible that the enemies could destroy the divine plane sects.
Fortunately, with those 30 Divine Realm elders that he killed helped to greatly decrease the enemies of the divine plane sects, but from what Zhang Yi had seen there should be more than 400 Divine Realm elders in that enemy army yet.
