"Xiaowen, what is this Ultimate Fire?" Chen Gang asked, somewhat puzzled.
Although Chen Gang had not previously broken through to Titled Douluo, he was already among the foremost experts in fire-attribute martial souls. Yet even he had never heard this term. He could not understand where his granddaughter's husband had learned it.
Ye Wen gave a soft cough, feeling no psychological burden whatsoever over his slip of the tongue.
Even if one knew of this concept, without all sorts of fortunate coincidences, ordinary Soul Masters would have no way of obtaining Ultimate Attributes such as Ultimate Fire or Ultimate Ice.
But since I brought it up, the right to define this term belongs to me, Ye Wen thought to himself.
After carefully considering his wording, Ye Wen explained.
"Grandpa Chen Gang, Ultimate Fire is exactly what the name implies—the ultimate form of fire."
Chen Gang instinctively wanted to refute him, because in his view, there was no upper limit to the temperature of flames.
(PS: Ye Wen thought so too, but this was the Douluo World, which had its own rules.)
Ye Wen directly waved a hand to cut off Chen Gang before he could speak and continued, "I know Grandpa Chen Gang wants to tell me that the temperature of fire should have no end, but my concept of Ultimate Fire applies only to Soul Masters of Douluo Continent. This is the limitation of martial souls. Ultimate Fire is the upper limit of martial soul flames."
(PS: The Godslayer-grade Soul Guided Cannon Shell from twenty thousand years later was similar to a nuclear bomb and directly leveled Shrek Academy. The explosion's core area, just like the ultimate result of a nuclear explosion, would form a glass-like region. Therefore, theoretically, Douluo Continent could produce flames even hotter than Ultimate Fire.
