Eiro let out a deep sigh as he looked at the ceiling. Sitting here in class while the students were taking a test was really boring. He would have nothing to do for the next half hour. Sure, he could read a book if he wanted to, but he didn't have any with him that he didn't read yet. So instead, Eiro resorted to simply manipulating his mana circuits to get more proficiency in that skill.
He played around with it a bit, seeing how random shapes and patterns in his mana circuits would influence the flow of his mana as it left his body in different places. His insight into his own mana increased by a little, but for the most part this was really just a way not to feel like he wasted his time.
At the end of the test, Eiro collected the tests, and then spoke to the students, "Alright, you can take a brief ten minute break. Talk to each other, do other homework, or just sleep, I don't care."
