Though Ren found the silence of both the Serbek Kingdom and the Reshcbauch Kingdom to be a bit unsettling he also found it quite exciting. The thought that he didn't know what's coming was making him feel exhilarated. Now that both sides have some idea of how strong he and his forces were should mean that the next attack directed at them would be stronger than before. Just thinking about the battles to come made Ren feel that his body was heating up.
Still, knowing that more powerful opponents were waiting to battle him, Ren needed to do but one thing and that would be to get stronger. It would be such a shame to fight strong opponents and not be able to fully enjoy it by dying prematurely. The only enjoyable battle would be a battle were both sides exhaust every ounce of their strength till victory is achieved.
