"This is his Heart Fire. Damn!"
Seeing Demon Refining Venerable's actions, Nie Yun's expression changed. He hurriedly retreated.
Heart Fire—the fire of the mind, flames formed from a single burning conviction within one's heart—possessed boundless power. Demon Refining Venerable was already immensely strong; the flames formed by burning his mind would certainly be even more terrifying. Even Nie Yun could only avoid its edge for the moment.
This move was an attack that killed a thousand enemies while wounding oneself eight hundred. Once the Heart Fire burned, the soul would suffer immense damage, and one's strength would plummet as a result.
Demon Refining Venerable currently had no physical body and was merely a powerful yin soul, making the consequences even worse. Yet precisely because of that, once his Heart Fire ignited, its power would be even greater.
Once touched by Heart Fire, there would be no flames on the body. The fire would appear in the depths of one's heart and soul. If it was not extinguished in time, the soul itself would be burned clean away, resulting in utter death.
