From what they learned, fires were categorised into nine ranks with rank nine fires being the weakest and rank one being the most powerful.
Based on this categorisation, rank nine fires included ordinary flames while chaos fire was the only rank one flame.
Intrinsically, Xiaomu, Shen Xu's wood element fire, was a rank three fire.
Unfortunately, it previously suffered an injury and its rank fell from three to six.
"Ayuan, Xiaomu can recover a little if it refines a few drops of fire jelly." Shen Xu exclaimed and Zhen Yuan nodded.
"The fire jelly can also purify your spiritual root fire."
"I know." Shen Xu nodded.
The chaos fire spiritual root was one of the most powerful spiritual roots in the cultivation world, immortal realm, and God realm.
However, its cultivation was extremely difficult.
At the moment, Shen Xu's spiritual root fire was more than ordinary but significantly worse than chaos fire.
