If Izroth wanted to increase the progress rate of his Boundless Emperor Void Perfection skill, he needed something known as the "Law of Void". Unfortunately, it appeared that items containing the Law of Void required a divine item as its vessel, otherwise, the power behind the Law of Void could not be properly restrained.
'But, is this truly the only path I can take?'
Izroth needed to increase his power as fast as possible in a short amount of time and this was the best method at his current disposal.
When Kryxelsia noticed that Izroth appeared to be in deep thought about the topic, she decided to leave him with a strand of hope. Even though she knew that it was unlikely to happen, she believed that it was not completely impossible. It was also better than leaving him with no path or goal. Besides, it might even ultimately motivate Izroth to push past his limits.
