Lia had already brought Jeric into the agreement to invade some independent dark sects. The benefits of getting more people were brought into his interest and, since it was already accepted, Lia had decided to use some of the remaining time to "distress" before the report.
She could just stay in her Northern Region room and wait for the maps and lists of dark sects, but she decided to go for a walk to see what the mortals and other people were up to.
Watching the people minding their own businesses, she realized how peaceful their minds were at peace. They don't know about the legacy and also the wars between the different continents.
It could be because of the buried past of the Great World War, but it isn't what matters the most. Lia's only wish is to finish this legacy and live like a normal being, gain experience in conversing with normal people, and travel to the Upper Heavens.
