The flames inside the pill furnace immediately surged, letting out a thunderous roar as a rich medicinal fragrance drifted from within.
Ye Ruoshui stared intently at the pill furnace, her right hand rapidly changing hand seals.
Whoosh! Whoosh! Whoosh!
Clusters of crimson flames shot skyward from the pill furnace, taking on all manner of lifelike forms as they churned through the air.
Ye Ruoshui suddenly slapped the bottom of the pill furnace with her right hand.
Rumble!
The entire pill furnace let out a tremendous boom and shook without cease. A pill, jade-green throughout, its surface etched with several fine patterns and emitting a faint fragrance, shot out and hovered in midair.
"This is..."
At the sight, the Seventh Elder's eyes widened, disbelief filling his pupils.
"Spirit Infusion Pill!"
The Seventh Elder blurted out those three words.
Emperor Xia and the others were equally astonished.
One had to know that the Spirit Infusion Pill was a Yellow-grade Supreme pill, far beyond a Yellow-grade High-rank pill such as the Ascension Yuan Pill. The difficulty of refining them was simply not on the same level.
The Seventh Elder could refine more than a hundred Ascension Yuan Pills each year, yet he could only refine a dozen or so Spirit Infusion Pills. The difference in difficulty was obvious.
"That is... a Pill Pattern?!"
Emperor Xia's eyes were full of shock.
One had to know that once a pill gave birth to Pill Patterns, its medicinal efficacy underwent a qualitative leap. Moreover, it would not decay even after a thousand years, making it far superior to pills of ordinary quality.
If an ordinary Mysterious-grade Low-rank pill and a Yellow-grade Supreme pill with Pill Patterns were placed together, anyone would choose the Yellow-grade Supreme pill rather than the Mysterious-grade Low-rank one.
That was the strength
