The Evil God's cultivation system has entered the sixth stage, where the differences between various calamitous beings are very distinct.
The Six-eyed Evil Clan transformed into a Great Calamity or Great Disaster are leagues apart in power from ordinary Six-eyed Evils.
As for the Empire's Star God cultivation system,
differences arise starting from the Fifth Rank, including General Fifth, True Martial Realm 1, and True Martial Second Realm, where the discrepancies are due to the number of A-level Spiritual Clothes mastered.
A True Martial Second Realm can use two A-level Spiritual Clothes, but if their spiritual quantity is depleted, there's still a great chance they could be overpowered and killed by exceptionally talented General Fifth Spirit Masters.
The differences after Ascension are primarily due to the number of Dao Fruits.
