Chapter 583: The Furnace Stirs
The figures of the Marquis of Jingnan and Gu Changfeng had barely surged several zhang forward when the Purple Heaven Refining Sky Furnace hovering in the air above suddenly produced a violent movement.
The purple true flames along the furnace body, which had been slowly subsiding, abruptly blazed up and surged outward. Like an enraged dragon awakening, they exploded in the direction the two men were coming from.
These were not ordinary flames, nor were they the kind of technique-fire produced by True Origin. They were the true flame born from the Purple Heaven Refining Sky Furnace itself, and within the tongues of fire, fine threads of purple Dao principle flowed and drifted.
"Fall back quickly!"
The Marquis of Jingnan growled in a low voice, and he and Gu Changfeng pulled back at nearly the same instant.
The true flame pouring out from the Purple Heaven Refining Sky Furnace was entirely unlike anything they had seen before.
What made both men's hearts go cold was not the temperature of the true flame, but that thread of purple marking flowing within the fire.
The marking was extremely fine, thin as a spider's web thread. Had both men not been high-level Grandmasters, they would never have perceived it.
Yet that single thread, fine as a strand of hair, caused both the Marquis of Jingnan and Gu Changfeng's faces to change simultaneously.
