Since the elf had said so, Ke'Oth and N'zall stopped trying to convince him otherwise and began talking about the problems they had encountered while growing their plants.
Ke'Oth: "Before planting these, I asked a human for advice. I followed their instructions strictly, even watering them down to the exact drop."
N'zall: "Every day, I make sure they get plenty of sunlight, even when it rains."
Ke'Oth & N'zall: "So we really don't know where the problem is coming from."
Illiya couldn't help but let out a chuckle. Seeing the increasingly resentful looks from the two demons, he quickly suppressed his laughter and composed himself, acting as though nothing had happened.
It wasn't that he wanted to laugh, it was just genuinely amusing.
