The purpose of the Black Iron-grade advancement gem is to help novice professionals advance in their careers.
Once each novice class reaches level 10 and has reached the experience cap, they can advance from a novice class to an Iron-level class using an Iron-level advancement orb.
Each Black Iron-grade advancement orb has a market price of two million, which is quite expensive for novice professionals. Moreover, it is often in short supply and has high demand.
As for skill books and skill scrolls, their purpose is to help professionals learn skills.
There are three main ways for professionals to acquire skills.

As the name suggests, skill books allow you to directly learn the corresponding skills without any unexpected issues.
As for skill scrolls, they can randomly grant you skills specific to your class.
However, the skills learned from skill scrolls are random, and you may also learn skills you've already learned.
Once you learn a skill that you can repeat, it means that the skill scroll has been wasted.
Black Iron-grade skill books and scrolls can only be used to learn Black Iron-grade skills, and the higher the grade of the skill book or scroll, the more expensive it is.
The price of Iron-grade skill scrolls is relatively stable, around 200,000 Dragon Kingdom Coins.
Black Iron-grade skill books are mainly judged by their skill effects, and their price ranges from 500,000 to 2,000,000 Dragon Kingdom Coins.
Of course, there are also extremely rare, top-tier black iron-grade skill books, whose prices far exceed expectations.

In this world, an average family of three would only need 100,000 Dragon Kingdom coins a year, and that amount of resources would be enough for an average family of three to live on for a hundred years.
