Where did you get this thing?

"Damn, bro!" Michael gasped when he heard the function of the small black thing. "Where did you even get this thing? And did you tell us just now that you have such an amazing artifact?"

"Well, I'm really planning to tell you, but I've decided to tell you once the quantity is enough."

James on the other hand, put the thing called a mobile phone in one of his pockets without hesitation.

"You didn't answer my first question... Where did you get that thing?"

"Where do you think I got that? In the secret realm??? No. I've invented it." Fein said casually.

"Hmmm... So you've invented it? Aweso- What!?? you've invented it!?" Michael almost choked with his saliva as he looks at his friend in disbelief.
