While the disturbance in the Giant Domain wasn't forgotten, it faded from the forefront of people's minds after a few weeks of silence.
The defensive line was definitely pierced, but with no signs of Nox in the universe at all, how could they continue prioritizing the matter above all else?
After all, fighting an invisible enemy wasn't something one could just do.
The sheer amount of manpower and security needed to completely turn the Giant Domain upside down was too heavy of a cost. In the current situation, investigative squads were the most Heaven's Army could provide.
Luciel's mind was fogged with problems. As the head of the logistics division, he was the main one choosing how the universe responded to threats.
Personally, he wanted to put everything into the Giant Domain regardless of the cost. He knew for a fact something terrible would happen if it was left alone, but he didn't have absolute executive power.
