"Don't be anxious." The opened eye on the bangle, which the little snake had transformed into, appeared to have a hint of panic. "Your physique is special, and therefore it's harder for you to learn black magic. But I'll try to think of something else."
After Fang Xingjian brought the little snake back with him, the latter had continuously tried to bewitch Fang Xingjian into learning black magic. However, it was just like the result of the aptitude test Fang Xingjian had taken in the past; he was incapable of picking up any black magic.
According to the little snake, black magic allowed one to borrow the powers of gods, using divine energy to change the objective world. Depending on the god the powers were borrowed from, there were a total of 12 different types of Mages, including the Black Robed, Gray Robed, Silver Robed, and Red Robed.
