Having made up his mind, Ling Qing prepared to forge the pill furnace.
Having comprehended the Myriad Dharma Spirit Treasure Dao Foundation, artifact forging posed no difficulty for him.
What was more, Zhu Guang was also a master artifact refiner.
To cultivate the Nine-Turn Golden Elixir Dao Foundation, one first had to use true essence to forge an Yin-Yang Furnace.
Ling Qing no longer needed to forge it with true essence, but this pill furnace was still an Yin-Yang Furnace.
It was a One-Qi Yin-Yang Furnace forged upon the foundation of Xiantian Primordial Qi.

It was a round tripod furnace the size of a fist, with three legs and four apertures.
Its body was round, its interior divided into upper and lower chambers, like the two aspects of yin and yang. Its three legs represented the Three Powers, and its four apertures formed the Four Images.
