Second Incandescence

Earth Flame Heart is an ore formed at the very core of the earth flames after several thousand years of refinement and tempering. It contains an incomparable quantity of fire energy, and if an ordinary cultivator were to just touch it, they would be scalded.

Usually, 6-star blacksmiths would use it as a coal to process ores which are exceptionally resistant to heat. Who could have thought that it would be used as a core to the formation of this Chamber of Earth Flame?

Under his Eye of Insight, Zhang Xuan could see the incredible profoundness of the formation before him. It was crafted in a manner that allowed it to take in spiritual energy from the surroundings to sustain the emanation of heat from the Earth Flame Heart.

As such, despite the passing of many years, the Earth Flame Heart was still brimming with power.
