The instant Cao Shenzi prepared to strike, Xiao Yan slammed his palm onto the alchemy furnace. In an instant, dense cracks spread across the entire furnace, and black flames erupted from within. The terrifying Black Flame blasted the approaching Cao Shenzi away.
With a thunderous boom, the alchemy furnace exploded. A violent wave of fire burst out from the furnace in every direction, shooting straight into the sky like an erupting volcano.
"Furnace Explosion!!"
"I told you, does Venerable Yan even know Alchemy or not? Why was he throwing in medicinal ingredients at random?!" an alchemist could not help shaking his head as he said.
"Hmph, I said he got lucky back then. How could an alchemist from a Lower Plane possibly surpass the alchemists of the Ancient Myriad Herbs Prairie? See? Once he tries to refine a high-grade Medicinal Pill, his flaws show." Some people also sneered, believing Xiao Yan had merely been lucky before.
However, as the Black Flame soared into the sky, the clouds above suddenly began to change slightly. The terrifying pillar of fire burned the sky, shooting straight beyond the ninth heaven and into the cosmos. The endless dark universe seemed to be warped by the Heavenly Flames, and a gigantic vortex appeared.
A vortex appeared above Xiao Yan's head, and sounds came from within it, growing louder and louder.
"That's... Black God Lightning!" Seeing the vortex in the sky, someone could not help exclaiming, "Heavens, he really did refine a divine-grade Medicinal Pill!!"
The Black Flame that surged into the sky formed a vortex of Heavenly Flames. That Black Flame vortex, like a black hole, directly devoured the thunderclouds along with the surrounding Spiritual Energy of heaven and earth, refining them into strands of incomparably pure worldly energy that merged into the Medicinal Pill.
