This world is a cultivation one and cultivation has just emerged on the world again after 1000 years. It's been about 500 years since cultivation reemerged, so all the side jobs/occupations are useless to most people that is why the mc family has so many books up to the 5-star level.
Occupations Info:
Apprentice - No star level - Just the basics in knowledge of mortal grade. The knowledge can be a huge amount or a little amount depending on the occupation. Like acupuncture requires a lot of knowledge before a person is able to even use it. But something like singing doesn't require much knowledge to fulfill the apprenticeship level.(Special occupations like singing have a more special system like this one but is fundamentally the same)
1-Star Level - Able to use the knowledge gained in the apprentice level very easily and is able to learn how to use it. Also the person must learn 1-tier grade recipies./ Able to do the basics of special occupations. Example: A blacksmith is able to identify all low-tier mortal grade ores just by examining them and is now ready to wield the hammer to try to make things.
2-Star Level - The person is now able to make good quality 1-tier items of the basic recipies. They now have good control over themselves while focused. Example: Able to make a basic healing pill, that is able to heal light injuries. A singer is now able to distract non-cultivators.
3-Star Level - Now a person can make best-tier quality items. Now a person has to study medium-tier mortal grade knowledge. The person also is able to stay in a focused state for an 1 hour. Example: A singer is now has a little chance to distract low level cultivators.
4-Star Level - A person is able to now make 2-tier items and is able to make perfect 1-tier items. Able to make the poor quality 2-tier items. Example: A singer is now able to use qi to distract low level cultivators.
5-Star Level - Are now able to make good quality 2-tier items. Now they have to learn 3-star recipies.
Special Explained a little bit:
For example a singer is able to learn different songs and depending on the songs a person is able to bring out different effects.
