Holding back

The blue fire took the shape of vermillion as Sauren punched towards the Crulior who let the fire consume him instead of dodging. Sauren was confident it was going to hurt him but he was proved wrong. 

The blue flames were already not natural flames and had a temperature several times higher than the normal one. If that Demon underestimated the fire, thinking it would be the same as the common fire he was going to get punished for his overconfidence, this was what Sauren had thought. 

But just as fire consumed him, Sauren felt his fist getting held by something. As the fire shroud went down, he observed Crulior clasping his punch like it was nothing.  Sauren was shocked to the core.
