Why was the requirement set to be below 30 years old?
That was because what a Herbalist needed the most was mental energy. Furthermore, a person's mental energy would be fixed the moment they turned 30. Even if Shen Yanxiao were to use 17 to 18 potions to improve their mental energy, it would be hard to nurture another genius Herbalist.
Moreover, the learning ability of ordinary people would start declining after they turned 30 years old. Therefore, she had set such a requirement.
This was the first announcement Shen Yanxiao had made since she became the City Lord.
For a moment, everyone in Sun Never Sets moved out. Those who had yet to reach their thirties crowded Uncle Nine to register.
Uncle Nine did some math. In just one day, there were already a thousand applicants, and there were still some more queuing up at the entrance.
