After the basics of martial arts was set up, next they had the system log in the martial rankings. There was Lower Realm, Middle Realm, Upper Realm, then after they reach upper realm they enter they will or will not enter the Martial Realm. After reaching the highest Martial Realm, they can either reach the Heavenly Realm or the Demonic Realm. And when they reach the top of either of those realms, they can reach a god-like realm that makes them damn near unbeatable.
This is what the complete ranking system looks like:

1. 1st Rank - Just started cultivating, went through basic body refinement, and basic breathing methods. May or may not have obtained their first technique.
2. 2nd Rank - Accumulating chi or chakra to gain more vitality and power. A little bit more powerful than a low realm, first rank martial artist. Honing first martial technique.
