"Huh...it's you?" the next day—or rather, the next evening—Natha's messenger came, and it was a familiar person, I mean, demon.
Wearing a robe and a human disguise, they had a male appearance, but I knew the demon form was genderless. But I'd just assume he was a male since he disguised as one. Anyway, he was the spy Natha planted in the kingdom, the one I chased and cornered to send my desperate letter to the Demon Lord.
I guessed Natha sent this one because I was more or less familiar with him?
He came after I finished my dinner, waiting on standby outside the balcony door with a luxurious box in his hands. He opened the box and politely showed me the content, which was an old-looking scroll protected by preservation magic.
I opened the scroll to glance at the content for a bit, just to see that it indeed contained the royal cultivation method. But I could peruse the content later since there was something more important right now.
