The strength and duration of the Tribulation Fire depend on how many years of Sinful Desire have been absorbed by the Dragon Tail, and Huang Zhaoyue only has three thousand years.
This thing is essentially a consumable, and a very expensive one at that.
With this Tribulation Transformation, there will likely be no chance to use it again, unless we wait for Huang Zhaoyue to accumulate several thousand more years of Sinful Desire, then Xia Feng can absorb...
But then again, Evil Dragon Miss's Sinful Desire definitely spans ten thousand years, or even longer. However, compared to Huang Zhaoyue, Evil Dragon Miss's status is too high, and it is uncertain whether the same method can be used for conversion.
