Ryu's pupils constricted.
The voice was like the eruption of a volcano and yet it didn't seem as though the Heaven's Warrior had tried to be so forceful. It was as though this was simply its natural cadence. It didn't feel the need to put in effort for such ants.
It didn't elaborate its meaning, it wasn't overly verbose, it simply spoke two short and succinct words. As for whether others understood what it meant, maybe it truly didn't care. But, wasn't its meaning as clear as day?
Who dared to fight against the Heavens?
As for why Ryu was so shocked, it actually wasn't because of this. He was caught off guard because he had already concluded that the Heavens was nothing more than a fictitious entity that represented the rules the world was governed by. The reason it was actually stupid enough to take out more rage on Ryu than the Martial Gods below who were actually responsible for all of this was simply because it was enacting its rules rigidly and without recourse.
