Fang Yuan held in his excitement.
The immortal material in his hands was of very high quality, even in his previous life, he had never owned such a specimen.
Quasi-rank nine immortal material, it had so many dao marks that it shined with bright light, observable with the naked eye.
Fang Yuan was not a grandmaster in refinement path, but he knew something, the reason why immortal materials could be used to refine Immortal Gu was because the immortal materials themselves contain a lot of dao marks.
Man is the spirit of all beings, Gu are the essence of heaven and earth.
Gu worms were the vessels of the Great Dao, why did they contain power? That was because the tiny Gu worm contained dao marks.
Dao marks were the traces of the Great Dao of heaven and earth, precisely because of this, activating Gu worms would result in many magical effects.
