After Li Bufan fed in the essence of two fifth-grade Spiritual Fires, the aura of the Crimson Fire Flowing Paste began to undergo an obvious change. The flames, originally tending toward a mysterious black, gradually became even deeper in color.
When he fed in another Spiritual Fire, the Crimson Fire Flowing Paste's color completely transformed from mysterious black into a pure black. Yet when Li Bufan injected a wisp of True Essence into it, it abruptly erupted with five-colored radiance—gold, green, blue, red, and yellow—blossoming in his palm with brilliant, magnificent splendor like an ignited star.
That was the hallmark of the Crimson Fire Flowing Paste breaking through into a sixth-grade Spiritual Fire. It had absorbed and fused every trait of those refined foreign flames, completing a leap in grade at its very essence.
Li Bufan felt the deeper power emanating from the black flames, played with them for a while, and only then brought them back under the control of his palm.
He continued taking out the remaining Spiritual Fire Seeds from his storage ring and refining them one by one. After every Fire Seed, including Ge Ming's sixth-grade Spiritual Fire, had been completely refined, the Crimson Fire Flowing Paste's aura surged once more. Even compared to the Great Sun Golden Yang Flame, it was not much inferior.
With a thought, he summoned the Crimson Fire Flowing Paste, Great Sun Golden Yang Flame, and Threefold True Fire at once. Flames of gold, white, and black slowly spiraled around his palm, like a carefully choreographed dance of fire, tracing smooth arcs through the air.
The heat exuded by the three Spiritual Fires was naturally terrifying, but he used his divine sense to restrain all of it within the range of his palm, without allowing even a thread to leak out.
