That Crimson Heart Meditation Law Set his younger cousin had given him had ten formulas, and furthermore, when he gave it to him, Lin Yun had repeatedly warned him that he shouldn't use the Crimson Heart as a core Meditation Formula. Lin Yun also told him that once he had completely mastered the Crimson Heart, he would give him a more formidable Meditation Law Set, and only then could he choose his core Meditation Law.
In contrast, what was a Meditation Law Set with only nine formulas?
In William's eyes, Solomon was only looking to start a fight. 'My cousin said you could keep it, so keep it, why stomp your feet like a child… A 9th Rank High Mage like yourself losing your composure because of such a formula… What about your reputation?'
It wasn't strange for William Merlin to think this way.
After all, he was only a Great Mage.
