Murong Ziyue's father sacrificed himself for the family, and before he died, he only left a silver note worth one million taels for her and her mother.
At the bottom of the wooden box containing the silver note, there was a hidden compartment, inside which a Spirit Art and a Cultivation Technique were concealed.
After Xin Lin discovered it, Murong Ziyue gifted that Sixth-rank Spirit Technique, the Enchanting Spell, to Xin Lin.
The remaining Cultivation Technique was a Dark-grade High-level Technique called "Glazed Ghost Transformation," whose rank was roughly equivalent to Xin Lin's Enchanting Spell.
After obtaining it, Murong Ziyue began to cultivate.
It's unclear whether Murong Ziyue truly had a high talent, or if the Ghost Transformation Technique was just very suitable for her.
In about a month's time, she made successive breakthroughs, cultivating the technique to the Second Level, and her True Qi surged, inadvertently forming a third Martial Meridian.
