Master Jing Yi's words were quite accurate; indeed, the real Purple Phoenix Hairpin was extremely powerful, but it also required a vast amount of True Qi to use. Without the cultivation base of the Qi Refining middle stage, it would be impossible to use.
Thinking back to Zhang Xiaohua's past, she had already reached the level of three or four stages of Qi Refining and could only use a Jade Talisman. The first time she used a magical artifact was the Binding Dragon Ring, which required the cultivation base of the Qi Refining middle stage. Even so, she could only barely control the Binding Dragon Ring and couldn't release the True Fire within it!
