Chapter 1210: Ji Tianxiong

"Purify one's bloodline or increase the tier of one's bloodline? How can there be something as convenient as that in the world?" Zhang Jiuxiao shook his head. "The purity of the bloodline of a Sage Clan offspring is determined at birth. In fact, there are many inner disciples who had the purity of their bloodlines verified even before their birth. Similar to unique constitutions, this is something innate. There are no external forces that can possibly change one's constitution and bloodline easily."

Hearing those words, Zhang Xuan fell into deep thought.

As he had never come into the contact with the Sage Clans before, he wasn't aware of many of their affairs. However, he did have two students with unique constitutions and one with a unique bloodline.
