It took one hour for Yvraine to finish all of the exercises that the Old Bahar imparted her, and she dutifully carried them every single day. It was clear that she worked very hard in mastering her Level 3 Ultimate Ability Metamagic and successfully incorporating it into her combat style and combining it with the Silvermoon Swordsmanship and her sword mastery as a whole.
While Yvriaine was training, Samiel started reading his Grimoires, as that was something he was doing when he was bored or had some time to pass. Even though he already went through the Grimoire he was reading, as that one was on the Basic Principles of the Void, it never hurt off to constantly repeat the basics.
