Elder Dark Bone was too famous in this Star Field.
In the eyes of many experts in this Star Field, if one wanted to choose the strongest Principles Master, it would undoubtedly be decided between the Blood Sword Master and the Blood Saber Emperor.
However, if they were talking about the most troublesome Principles Master, 99% of the people would immediately think of this Elder Dark Bone.
This Elder Dark Bone was famous for his many tricks and was extremely difficult to deal with.
He had faced many Ruler-level experts on more than one occasion. He had even faced high-level Rulers directly. The other party had used all of his tricks, but he was still unable to do anything to him.
He had even dared to scheme against Rulers in this Star Field. Because of this, he had offended quite a few Rulers, but so far, he was still alive and well.
