This batch of treasure pills consists of a total of thirteen, each displaying two colors, purple and green, resembling the Tai Chi Diagram, where two Yin-Yang fish chase and merge into a single Spirit Pill.
From them emanates a faint five-colored radiant glow, with a mysterious Dao Rhyme flowing around.
Just as the furnace was opened, unexpectedly, a whiff of the pill's fragrance broke through the restriction, leaking out slightly.
Fortunately, Gu Yuan reacted swiftly, putting away the Spirit Pill quickly, otherwise the severe loss of the pill's fragrance would inevitably harm a part of Primordial Qi.
Thirteen Spirit Pills spun around in front of Gu Yuan and were directly swallowed as he opened his mouth.
Following that, Gu Yuan's Heaven and Earth Devouring Divine Techniques were immediately activated, along with the "Red Fetus Roasting Furnace Scripture" he practiced, taking merely the time of a cup of tea to devour and refine these Spirit Pills thoroughly.
