The moment everyone saw Shen Jinzhe's blue flames, they were surprised.
Before, they had seen their captain's black flames. Now, they were seeing their brother's blue fire. It seemed that fire-type abilities had more variety compared to other elemental-type abilities.
While the soldiers stared at the fireball in awe, both Jin Xuyan and Jiao Lizhi were surprised. Even though fire-type ability was categorized as one of the strongest attack-type abilities, their power depended on the fire itself.
For example, Shen Jinzhe's blue fire—due to its temperature being higher than an ordinary fire-type ability—was classified as a high-grade fire type. Meanwhile, red fire was classified as low-grade, and orange fire as intermediate-grade.
As for Jin Xuyan's black flame, even five years after the end of the world, no one can determine its grade.
Each elemental-type ability had grades that differentiated their power and strength.
