Ha, revealing everything before you even saw the enemy's powers. Yamamoto's gonna lose...
Haha, 15 million degrees? He should have melted everything around him.
His blade is 15 million degrees hot, hence why he can ''cut'' anything with it. Before his real blade even hit, anything that is in the blade's trajectory is burned to ashes in an instant.
Also he compress that heat around his blade (And his armor when he bring it) so it's pretty much safe to assume that he keep most of the heat under control.
Basically even though his blade and armor are 15 million degrees hot, it's pretty safe to say that at a hundred metter or so it's still fucking hot but still 'liveable' for shinigami and people with lot of control over reiatsu.
