"Actually, I was kidding about that pair of fake ears, they are not useless. If you wear it, you will be able to hear anything I say, even if we are separated by ten kilometers."
"I didn't know you liked that kind of joke. I thought you were a very serious woman, but in reality, you're just putting up a front, huh?"
Elyra ignored his comment and continued: "There is a mini profound formation imbued within it."
Elyra didn't gave him useless things, it was a set of items that was necessary for them to work together.
"Mini profound formation? How does it work?"
"Put it on and try to channel some of your Mana on the item."
Seth put those fake pointy ears on and thought his appearance was kind of ridiculous, since he wasn't as thin as a normal elf. However, he knew that people would not doubt him being an elf at first sight at least. He put a bit of his Mana on the item and Elyra said some words to test it.
