Sophie heaved a sigh of relief, seeing the magic circle forming on the surface of the mana core.
Gradually, she moved all the Earth mana to the mana core, and all those Earth mana from the Stone Skin Potion were sucked dry until the magic circle finally finished.
That was then, she could hear the mana core humming in joy before turning quiet.
She was surprised.
To think the mana core actually possessed an intelligence, even though it was only comparable to a child.
However, from what she recalled from reading books, those mages said their mana core was their soul, their child.
She only thought they were exaggerating but it was actually not the case.
Suddenly, a weird thought appeared in her mind.
'Do I have to take care of another living being aside from her Young Highness?'
She quickly shook her head.
She checked the mana core once again, now turning lifeless, and was assured to see the magic circle on its surface.
