Blood gem

"It's alright, brother. This grade-four blood gem is enough for me." Amara smiled sweetly. As a three-star mage, the highest grade of blood gem she could use was grade-four gem which she just got.

"Mm? How do you know there is a grade-four blood gem and not a grade-three?" Ashroth asked curiously.

"Hmph! Big brother, do you think I'm that naïve girl I was two years ago?" Amara snorted in displeasure and then added. "Given how arrogant and prideful that cheap bastard is, he wouldn't have given a gift lower than his realm's equivalent, even if he wanted to humiliate you."

"Hehe. So, you've finally become smart. That's good." Ashroth grinned teasingly, but there was a glint of hidden remorse in his eyes. 

Two years ago, this sister of his was naïve and carefree. She never paid attention to anything and would only focus on having fun. But now, she has changed so much that she was even paying attention to such small details.
