In terms of efficiency, it was much more efficient than "Spirit Elegy", but its upper limit was nowhere near as high.
After reaching "Limit Burning", "Soul Firewood" was needed to raise the "Position" of the Star; otherwise, it was impossible to add more fire.
Now, the material for "Soul Firewood" was no longer a difficult task for Rod, but "Divinity" was.
Creating "Soul Firewood" required a portion of Divinity, which is 10 points, but Rod only had 6 points.
Therefore, the enhancement of this Star could only stop here for now.
Rod injected all the remaining 210,000 Souls Without Spirit into "Spirit Elegy".
It was a super Star designed to enhance Spiritual Energy, with a terrifyingly high limit, and correspondingly, its energy consumption was terrifying as well.
After adding so many Souls Without Spirit, its state had only advanced from "Blazing Burning" to "Overburning", and its strength had only increased from 3010 to 5015.
The ratio was about 1 to 110.
