Northern Plains, Bone Burial Ground.
This was a land of white bones, densely packed skeletons piled together.
Some bones were enormous, like small mountains; others were tiny, so inconspicuous that one would not notice them even at one's feet.
Most of the bones were a ghastly white. After enduring wind and sun, their flesh had long since been digested by nature. Only these bones bore the imprint of the toughness that the desolate beasts and ancient primeval beasts had possessed in life.
But some bones carried strange colors. Some gleamed with a golden luster, while others were a bewitching purple, releasing poisonous smoke.
Gu Immortal Liu Yong paid close attention to them.
He was of golden bloodline, a Rank 6 Gu Immortal of Liu clan's enslavement path.
At this moment, he was controlling six bone armor dogs as he walked through the Bone Burial Ground, searching for targets.
There were many different explanations for how the Bone Burial Ground had formed.
Some said that, during the Ancient Era, this had been the site of a life-and-death fierce battle between two great enslavement path experts, resulting in the deaths of many desolate beasts and ancient primeval beasts.
Others claimed that this was the graveyard of bone monsters. When countless bone monsters sensed that their end was approaching, they would choose a place and bury themselves there.
Still others speculated that, in the immemorial era, a Refinement Dao Grandmaster of the Northern Plains had deliberately established this as a wondrous Gu-refining ground. After the changing tides of time, it had gradually become what it was today.
No matter what, the Bone Burial Ground did indeed contain an enormous number of desolate beast and ancient primeval beast remains.
Liu clan controlled this place and managed it carefully, turning it into a production base
