Yellow-robed Supremacy's brows pricked up as he carefully studied Qin Yun.
Yellow-robed Supremacy did not find it odd that Qin Yun said he 'self-created' his Dharmic Formulation. He had even guessed it.
If it wasn't self-created… Qin Yun would have had to have learned it from someone else. That would mean that the Dharmic formulation had long been created. With the fame of the sword immortal lineage in the Three Realms, it would be impossible for such a feat to remain hidden. For example, there was the Grand Supreme Dao Ancestor who created the Grand Supreme sword immortal lineage, he and others would have sensed it when a new Sword Immortal Essence Soul Dharmic formulation was created.
If Qin Yun had learned it from someone else, the upper echelons of the Three Realms would have long heard of this other person. Yellow-robed would definitely know of it too.
"When did you create it yourself?" inquired Yellow-robed Supremacy. "Have you told anyone else?"
