After obtaining Hellfire, the first thing Saine did was study the properties of its flames.
Next, Saine also considered finding a way to integrate it into his own Ashes of Fire.
There were only so many fire worlds within Wizard Civilization territory.
Saine could basically obtain any rare Rule Fire there was.
But clearly, the Yan Emperor Divine Clan possessed a greater number of rare flames, and their rule characteristics generally differed significantly from those of Wizard Civilization.
Throughout his research into this Hellfire, Saine repeatedly gained new insights.
At the same time, the Wizard Civilization Expeditionary Force's conquest of the Sky Prison Fire World proceeded in an orderly fashion.
This world was quite large, especially the vast space extending downward.
Every so often, the loyal guardian Fumila would make a special trip to deliver Saine some rare Rule Fires discovered on this large fire-element plane battlefield.
Naturally, the rule flames Fumila delivered could not compare to the Hellfire Saine had acquired from the Plane Navel.
However, these rule flames were generally suitable for Level 4 to Level 6 beings.
And there were quite a few of them.
There were also certain origin flames extracted from the bodies of Evil Tide powerhouses. They actually possessed strange demonic properties, making them well worth Saine's careful study.
