Axelle didn't know the old woman's ability, but ever since he took away a part of the grandma's domain, the elf felt something was wrong with the part he took.
Maybe because the first layer of the domain, the immortal domain, was an illusion, so when Axelle took away that part, what he took away was also an illusion.
The illusion was so real that even Axelle didn't realize that the true appearance of the old woman's domain might not be the heavenly immortal domain.
However, Axelle was also someone who had the blood of the abyss demon king, so something like illusions, no matter how strong they were, would also give off a strange vibe.
This strange vibe was enough to alarm Axelle, making him wary of what he saw, touched, sensed, smelled, and everything he experienced.
