Bringing an end to the mission.

The problem with having safe team tests like these was that they ended too quickly, meaning there would be no break.

The students continued their lessons the following day, and although it was more stressful as usual (mostly because of Zirrack), Blake made a lot of progress.

From the last fusion class, Blake realized that he was meant to fire both elements as a single entity. So during the 1st fusion class of the week, he did exactly that.

It involved simultaneously activating both fire and lightning pathways before firing both of them from the same palm.

He got it right from the first instance, but he soon noticed that although it wasn't as mana-consuming as his previous technique, it drained a lot of mana.

By the 2nd class, Blake began working on the efficiency of casting plasma fusion spells.

Throughout the 1st half of the class, he didn't accomplish anything, but in the other half, he received an epiphany.
