Cultivation will be divided into 7 Huge realms all the realms will have 14 sub realms the power difference between someone on 1-1 and 1-14 would be 4x. After 7-14 comes godhood which will have its own grading system and I have no idea what it should be like
Skills will have the same kind of grading they would go from 1-1 to 7-14 than they would reach god-tier skills and as I said I have no idea what kind of grading I want to do for god-tier
Tier 1 = junior cultivator
Tier 2 = senior cultivator
Tier 3 = master cultivator
Tier 4 = grandmaster cultivator
Tier 5 = expert cultivator
Tier 6 = saint
Tier 7 = demigod
If someone is 7-4 you can say 7th tier 4th subtier or 4th subtier demigod.
For skills
Tier 1 = starter-grade
Tier 2 = low-grade
Tier 3 = Intermediate-grade
Tier 4 = high-grade
Tier 5 = expert-grade
Tier 6 = saint
Tier 7 = demigod
The energy in this world is called generic energy and it can be used to nourish body and can also be used as like a magic but there are some people that are born with certain deficiencies that cant use it like magic or some people that can't use it to nourish their body and this isn't that big of a deal because after reaching 1-7 it is really hard to continue cultivating in both ways so 99% of the people just give it up and cultivate in one way but geniuses mostly cultivate both ways and become formidable masters.
