The Cyan Yuan Sect's Earth Fire Institute.
Yang Chan stared at the roaring Earth Fire, his expression unchanged. Having refined herbs many times in the Earth Fire Institute, he knew the flames wouldn't splash out.
Although the Earth Fire here could be unstable at times, it was impossible for it to erupt. The Cyan Yuan Sect arranged for regular inspections, and if any signs of a buildup were discovered, the fire would be diverted to prevent an eruption.
Any significant change in the Earth Fire would also trigger an inspection. When it came to the Earth Fire, the sect was exceptionally diligent.
Yang Chan's gaze, however, was fixed on the Alchemy Furnace to his side.
He was currently refining the First Revolution Nourishing Viscera Pill. It was more like a true elixir than the Lantian Jade Refining Pill, and its refining process was naturally more complex.
