Hades, as the ruler of the Netherworld, was second only to God King Zeus in status.
Moreover, as the lord commanding the Netherworld, both his strength and position were far superior to that of ordinary top-level divine beings, even slightly higher than the twelve main gods of Mount Olympus, aside from Zeus.
Therefore, he couldn't stand the arrogance of the Titan Giants, acting as if they were still the mighty Divine Clan of old when they were clearly past their prime.
Had it not been for the fact that this fellow usually stayed within his own territory and rarely caused trouble, coupled with the current resistance against the invaders from the Biluo Great World, Hades would have liked nothing more than to give this towering figure a proper lesson.
However, in that moment, Hades took a deep breath, reminded of the plan he and the other twelve main gods had conceived to deal with these invaders from beyond their realm, and ultimately chose to swallow his pride and not lash out!
