Most demon spirits, including God Level growth rate ones, don’t start out very powerful. A demon spirit requires care from their Demon Spiritualist, in the form of nourishment by Heavenly Energy. In fact, demon spirits require so much energy that they would need to absorb some Demon Soul’s Essence to become stronger and constantly increase their rankings.
Only after ranking up, the growth in strength would be higher for those higher ranked demon spirit compared to those that are lower ranked.
For example, if you have two 3-fate demon spirits, the one with the God Level growth rate will have a combat ability that’s a dozen fold stronger than the one with the Ordinary Level growth rate.
However, a demon spirit’s quality doesn’t increase only in terms of rank. Sometimes, a demon spirit might mutate. When such an event occurs, the demon spirit’s combat strength becomes much stronger.
Nie Li’s Shadow Devil and Fanged Panda had both undergone their first mutations. The more mutations a demon spirit experienced, the more precious it would become!
Usually, there’s a set probability to whether or not a demon spirit will mutate upon ranking up. However, this particular demon spirit had mutated during the fusing process instead. The price of such a mutated demon spirit must be greater by several dozen fold!
Nie Li didn’t know if this demon spirit had mutated by itself, or was influenced by the Nightmare Demon Pot. Either way, it was still good news to him.
Nie Li continued refining demon spirits. It wasn’t until the appearance of the second, and then the third mutated Dragon Bloodline… Now he was sure that it was an effect of the Nightmare Demon Pot!
From the thirty thousand Dragon Bloodline demon spirits with Ordinary Level growth rates, Nie Li only managed to produce about two thousand five hundred demon spirits with Good Level growth rates. And among them, twenty-three had undergone a mutation.
Nie Li repeated the refinery process with the new Good Level growth rate Dragon Bloodlines. He experimented by placing nine regular Dragon Bloodline demon spirits with one mutated one together in the pot.
A brief moment later, an explosion occurred inside the pot. All ten demon spirits had disappeared, making the refinery process a failure.
Was it an accident, or were regular Dragon Bloodlines refinery-incompatible with the mutated ones?
Nie Li pondered over it briefly and decided to repeat the experiment. If he didn’t try it out several times, how would he know for certain?
The second attempt ended with another failure.
The third attempt finally succeeded; Nie Li had created an Excellent growth rate Dragon Bloodline. On top of that, it is a mutated one.
