The sudden deluge of information so casually given by the goddess of creation broke Hao Ren's train of thought. Since he had to reevaluate his assessments and guesses about the Umbral Realm and L'Haronne, he quickly asked for more details from the latter after the explosion.
Soon, he understood many secrets regarding the events after the end of the Deicidal War.
In line with the information they had garnered earlier, the Deicidal War itself was a "planned conflict" the goddess of creation had orchestrated behind the scenes. The entire process of the deicide to the explosion of the heavenly kingdom was expected. As the godslayers destroyed the goddess' body, the boundless energy woven within the Star of Creation blew outward and engulfed the kingdom as well as a large swathe of the universe in a massive apocalyptic explosion, tearing a section of the dimension apart and flinging it towards the edge of the world.
