Blood Jade was the kind of person that was cruel by nature. He had killed countless people and placed great importance on himself, making him extremely selfish. Such people disgusted Yi Yun the most. Using the pure Yang broken sword to kill him would be an insult to the Pure Yang Sword Palace owner. Instead he handed Blood Jade over to Xin'er and company, which was also a way to have them avenge the countless girls that Blood Jade had killed.
With their metal shackles destroyed by Yi Yun, the girls from the Divine Secrets Trading Company felt their strength restored.
Their helplessness, despair, and feeling of living death had vanished in a blink of an eye. Their freedom was restored.
"Thank you, Young Master Yi, for saving our lives."
