All people start off with basic stats of 1 all around when they reach adult hood. They can increase them by training. Military training of any kind will typically bring someone between 1.2 and 1.8 in each stat. While cultivation Techniques can increase them even further. Depending on the technique different stats will be raised. If one has a technique like our MC's that is considered complete they can increase all of their stats through it.
Cultivation levels:
Beginner: 1.2 to 2.0 in the respective stat(s)
Initiate: 2.1 to 3.0
Intermediate: 3.1 to 5.0
Master: 5.1 to 10.0
Grandmaster: 10.0 to 20.0
There are ranks beyond Grandmaster however I have not decided on those yet. to give an example of what these number mean each whole point up doubles the previous attributes bonus. So say someone with 1 point in strength can lift 100 pounds (lbs) then someone with 2 points can lift 200lbs, someone with 3 points can lift 400lbs, someone with 4 points can lift 800lbs, and so on.
