Roy stood where he was for a while and found that nothing had happened, so he could only try again.
He thought that the fluctuations were something like spatial fluctuations, but this time, Roy was prepared and realized that he was mistaken after experimenting again.
The effect of the fluctuations turned out to be a disturbance to the power of the world!
The moment he activated the scroll, Roy found that the repulsive force of the world that had been acting on him all along, and had been continuously strengthening, had an intense change in strength. It suddenly became much stronger before falling back to its original level in an instant. Although this change happened very quickly, he was able to feel it when he sensed it carefully.
Roy immediately realized that the effect of activating this scroll was probably another type of 'expulsion prayer', and it belonged to the expulsion prayer used by demons!
