Immediately after,
Shen Feng's vanished figure suddenly appeared in front of Zhou Yizhi and Zhao Penghai.
"Primordial Fire Heaven Transformation!"
With a "puchi,"
the Nine Nether Azure Flame surged explosively from within Shen Feng, and the temperature in the surrounding space skyrocketed in an instant.
The deep blue flames expanded in a flash and instantly enveloped his entire body.
At this moment, Shen Feng, with deep blue flames swirling around him, and blood-soaked from head to toe, his hair fluttering in the wind, appeared even more demonically enchanting.
Primordial Fire Heaven Transformation did not fall within the category of Immortal Techniques; it was an attack method that leveraged one's own Lifebound Flame to boost combat capabilities.
However, this technique was extremely difficult to control; every cell in the user's body had to be perfectly in sync with the Lifebound Flame for its power to be fully unleashed.
