Chapter 1558: A Stronger Soul

-----

After having devoured Pandemonium's Lung, I forced my soul to transform into countless chains that chained down the rest of the Lung's powers. However, after forging my Demonic Physique, rising my Demon King Seed Rank, and cultivating my Demonic Energy, Divine Power, and Spirit Essence further, I was able to breakthrough once more.

My soul expanded, resembling hundreds of rivers of gold, rainbow essence that constantly flowed upwards. The demonic soul energy that had been assimilated into my wounded soul slowly started to meld better, although it still remained restrained. I was slowly unlocking its powers. However, the chains disappeared, melting into this sea of gold and rainbow essence. It felt as if I had broken through a shell, and the System messages really took that literally. 

[Your Soul has broken through its former shell and has progressed to the next stage.]

[Your Soul Ether Stat has increased from S+++ to SS-!]
