"He paid more attention to the jewel while having a hard time not showing disappointment on his face. It was certainly the highest grade jewel of the first-class. He collected it for the time being just in case it might become a clue to something.

When he turned his attention to the map, the markers for the monsters, which had escaped from the battle with the two, that he was able to perceive, seemed to have disappeared. There was a little individual monster which escaped the purification too, but it seemed to have faded away with the Lord’s defeat. Either way, the Lord was the cause of this disturbance.

The light that illuminated the surroundings was weakened when Shin confirmed it with the map. As he might have expected, the effect of 【Sanctuary】 seemed to gradually stop. When the light completely faded away, the surroundings became dark, although it was still lit by the moonlight.

And, a big change, as a result of defeating the Lord was visible on the plains. Though he didn’t see it because of the strong light of purification, the demon essence drifted smokily up to the sky from the whole plains. With the spectacle of demon essence floating up, the light seemed to dissolve into the night sky.

The scene that happened over the whole plains caused the surrounding knights and adventurers to remain on lookout.

The demon light that soared up high at the same time as the holy light that repelled the darkness faded out into the shades of the night".
