"No, you fucking idiot! How the hell did you get into this school?!" a completely different version of Professor Tenningbrew spat at a young Gerwin Finst.
The boy in question was looking down in embarrassment while his entire left arm was hanging by a single thread of muscle. His hand swung back and forth on its own, brushing against the floor in the process.
Just a few minutes earlier, Professor Tenningbrew was working with Gerwin to improve the boy's current refinement of his Mana Circuits. Since there was such a small group remaining in the class, the Professor didn't bother taking Gerwin anywhere private during the process.
He simply raised a privacy wall that William could easily see through with his Vision Talent, then asked Gerwin to cast a weak Spell of any Element. It was supposed to be a simple test, but little did Professor Tenningbrew know that Gerwin started refining his Mana Circuits from his shoulder, and not his hand.
