Moreover, when this skill was upgraded in the future, the range could even be increased further. However, the burden on mental strength would also increase.
A divine level skill was indeed worthy of being a divine level skill. Although it only dealt 10% damage in terms of spell strength, when Lin Feng released the sea of flames at that time, the Iron-Winged Birds were all hit. Although he did not insta-kill them, in just a few seconds, those Iron-Winned Birds were also reduced to ashes.
The reason why Lin Feng was shocked was because his mental strength was too low. With more than a thousand mental strength, he could only completely control the sea of fire within a thousand meters. As for the sea of flames outside, he had almost lost control at that time.
Lin Feng had no choice. At this moment, his mental strength had already reached a limit. If he wanted to continue increasing, he probably had to break through to the bronze level.
