For the rest of that day and the day after that, Finn continued practicing his Lightning Breathing technique. Here and there, Lei would teach him some more advanced Stormbringer Abilities as a break, all of them which he managed to learn first try.
The same, however, couldn't be said about the breathing technique. Finn only had a short amount of time left before Thursday hit and joint training with the Big Five would begin — it was now the night before, but he still hadn't reached mastery.
"… That's all the time we have today," Lei said, standing up. "In the end, you didn't manage to get it, but don't be downed. It took me ten years to master this technique, after all. I just wanted to teach you how to employ it and what it does."
"Thank you, Patriarch," Finn replied briskly but politely, getting to his feet as well and preparing to leave the room. "I will master it, someday."
