The Divine World is the world where everyone has the opportunity to achieve immortality, but that doesn't mean everyone is the Gods and Immortals. There were still many mortals below the 10th Rank.
The spiritual energy in all layers of the Heavens was much higher and purer than the lower realm, but the Heavens weren't as peaceful and beautiful as Elysia imagined, pretty similar to the Earth's Heavens.
"So, the Heavens are just like the higher realms." Megami commented after observing the five layers of Heavens she had passed through.
The upper layers were relatively peaceful because the powerful Gods and Immortals who lived there could live in seclusion, rarely leaving their territory. Not to mention the heavenly laws implemented by the Heavenly Palace in the 8th layer, directly supervised by the Heavenly Dao and Heaven Rank top-rank members.
The middle layers were more or less peaceful, but disputes and commotion often occurred here and there.
