Nine-Life Sword Technique, Splitting Light in Great Void

Ling Feiyu met Zhang Ruochen again only three days after the last time. But Zhang Ruochen now was changed and his cultivation had reached the peak of First Level Half-Saint.

Even though Ling Feiyu had experienced much, she was still surprised by him.

"What speed! Even the help of refining divine blood couldn't enable you to break through from the primary to the peak of First Level Half-Saint in three days. Did the Patriarchs of the Taotian Sword use some mysterious ways to force your cultivation to go up?" Ling Feiyu asked with doubts.

All Half-Saints must have extraordinary bodies and talents, no one was common.

But why did it take all others one year, and even up to ten years, and only three days for Zhang Ruochen to get there?
