Chapter 651 Refining The White Bone Gu

Ye Tian re-entered the cave. Having read the booklet, he now understood the purpose of the ninety-nine piles of white bones. The first pile was used to cultivate the initial generation of white bone gu. After three years of cultivation, those that met the criteria were chosen and transferred to the second pile of white bones. Through continuous cultivation and selection ninety-nine times, the white bone gu that ultimately met the standard would be placed in the white bone pit for the final transformation.
