The Blood Moon Sect's main cultivation technique was not based on the spirit root, and thus, most of the elixirs they desired thousands of years ago were different from other cultivators. This Source of the Marrow Pill was one of the superior elixirs that they desired.
However, the formula for this pill had been lost for years, and the Blood Moon Sect had spent much effort but was still unable to find its trace even before it was exterminated.
To date, the words 'Source of the Marrow Pill' were no longer in one's knowledge.
Ye Qingtang was only barely over ten years old, how would she know about the Source of the Marrow Pill? And how was she able to have a real Source of the Marrow Pill?
A smile emerged in Ye Qingtang's eyes as she looked at the Blood Moon Sect Elder, who tried to maintain his composure.
