In the domain space.
Li Yuanqing was sitting upright in front of the golden alchemy furnace. His body was emitting a thick fog and was covered in sweat.
In the alchemy furnace, a red flame kept flickering.
Li Yuanqing stared at the fire with burning eyes, not daring to look away for a moment.
Below the alchemy furnace was an entire ball of flames. The flames spat out faint purple flames that emitted a scorching temperature, roasting the entire alchemy furnace to a very high temperature.
This flame was very simple and crude. It was a spiritual fire produced by the fire seed and spiritual power. This kind of fire was more natural and barbaric, and it was slower to control.
The flames produced by the array formation that Wang Lan used were even more special. It was also the fire that the alchemists in the Immortal World liked to use the most. Only by controlling every trace of precision could they satisfy the precision needed to refine pills.
