"Who are you calling old thing you disrespectful brat! Have I been so nice to you that you forgot I'm your mother?!... Hmph! You're lucky I'm not petty or you would regret what you said right now. Anyway, inject your mana into that phone and you'll understand..." Mrs C rebuked Muku a bit then moved on.
She refused to stoop to his level... Bullshit! She knew that it was her fault in the first place. So instead of being shameless, she decided it was best to move on.
"Okay", Muku replied without saying anything confrontational as he did what he was told.
He didn't dare push her any further or she really might do something. It would be unfair if she did, by it wasn't like he could do something about it...
Anyway, the moment his mana touched the "phone", it reacted. It began glowing faintly. The more mana it received from him, the brighter it glowed. Noticing that, he didn't stop injecting mana into it.
