An Jing had been practicing the Sun Strafe Art recently. Although she had improved greatly, she still failed to grasp the true meaning of the Sun Strafe Art required to advance to the Epic stage.
With her talent, it shouldn't have been difficult for her to advance to the Epic stage. However, due to her body's chronic ailment, she was unable to sense the underlying sublimity of the Sun Strafe Art.
An Jing wasn't afraid of hardship. Every time she cultivated the Sun Strafe Art, she could endure the inhuman pain caused by the chronic ailment.
However, gaining insight into something like this couldn't be resolved just by suffering. The untalented might not even be able to match a day's enlightenment of someone even after ten years of training.
