Ling Hua did not cultivate in the Jade Mirage Sect since she was a child. Instead, she was brought back from the foot of the mountain by her master, Sheng'e.
She was originally born into a prominent mortal family. When she was seven years old, her family changed. No one knew what happened to her. But a night of fire almost extinguished the whole family, leaving only her in the ruins of burned charcoal and corpses. The last sword strike was almost about to fall. If not for the stroke of luck that allowed her to dodge this misfortune, there would be no one named Ling Hua in the world.
After she was carried up the mountain by Sheng'e, she took the Dharma name 'Ling Hua' and abandoned her real name to show that she had cut off all ties with the mortal world.
