Derek

Derek is a Wind Elementalist with a low-grade talent and he wasn't great at cultivating.This was the reason he was in the city instead of an Academy.

There is usually a test made by the Academies. If they notice a student isn't making any improvements, the student will be dropped. The pressure and competition at the Academies are really high. Derek and his friends were part of the students dropped. Although he was dropped, he was still in the 8th stage of the Collection Plane. His age should usually have broken through to the Fusion Plane by now.
