"Times are changing."
Isius began to explain: "In the beginning, there were no professionals in the world, whether they were giant dragons or titans, they were all born as the powerful People of Gold."
"But as time went on, the elves appeared and created the system of spellcasters."
"From then on, power was not only obtained through innate abilities, but also through acquired efforts."
"After the Silver Age, professions like knights, priests, and berserkers began to emerge one after another..."
"And now, even a person with no bloodline from the People of Black Iron can become a professional through hard work as long as they have the corresponding talent."
In short, the times are constantly changing.
As time goes by, the professional system is also changing and more occupation systems are emerging and slowly developing.
Like the spellcaster system, it was initially a power that could only be used by elves with an elven bloodline during the Elven Empire's era.
