But getting back to the matter at hand.
The Martial Artist Technique Rankings were ranked in this order from lowest to highest:
1- Practiced
2- Accomplished
3- Minor Completion
4- Greater Completion
5- Mastered
6- Integration
Cassius being able to advance the |Fiendish Demon King Arts| to Greater Completion was already a grand accomplishment. Yet, it wasn't the only technique he progressed to Greater Completion, as he also got his |Demon Dragon Integration Arts| to Greater Completion!
With the former technique, he was able to embark on the Path of the Demon King, which was something that any number of Demon Kings would kill to have. However, seeing as only the Top 5 Demon Kings were privy to how to start and progress on the Path of the Demon King, the other Demon Kings could only devour each other in hopes of becoming stronger. They could also take from human blood sacrifices in the mortal realm, but that method was highly impractical.
