Lu Ye spared Xiang Yin's life; firstly, because he really needed to gather some manpower. Xiang Yin had enough strength and was clever enough, making her a suitable candidate. Moreover, if he were to kill Xiang Yin, he would also need to kill Xuan Yu to eliminate any future trouble.
Secondly, he had the means to control Xiang Yin.
This method was naturally to have her refine his treasure blood and make her his Blood Servant.
Once she became his Blood Servant, there would be no concern about her rebelling. By then, she would be as loyal as Ma Shangsi!
When a drop of treasure blood appeared at Lu Ye's fingertip, it instantly drew the attention of Xiang Yin and her sister.
Both women felt a strong attraction to this drop of treasure blood, a primal longing, yet alongside this lure, they could sense the terrifying danger hidden within the blood.
"What is this?" Xuan Yu asked.
She had never seen treasure blood before.
