Actually, Third Shadow didn't understand how Seth was so perfectly standing in the middle of that fire storm. The temperature and aggressiveness of that fire was enough to turn anything into ashes in a matter of seconds, and if not for his super strong level of cultivation, he would be dead already. However, Seth didn't even seem to be protecting his body with Mana at all.
A practitioner was resistant to the element he trained with, but it was still able to harm him or her while confronting practitioners that used them too.
"Heh! Let's see if you will be able to withstand this." Seth said while already revolving the Crimson Corrupted Energy inside his energy veins. It easily merged with his Fragmented Law of Fire, turning into something deadlier.
His fire storm suddenly started to get hotter and hotter, till that yellowish-orange flames turned crimson colored. Those crimson flames increased the heat to another level.
