My Thunder's Thunder Cross Is of No Use to Big Thunder's

It doesn't matter if I can't use my magic power, my mouth isn't very easy to use either. A former genius who had high hopes, but found that he couldn't muster decent magic power at all? To make matters worse, there seemed to be something wrong with his Thunder mind. As for language and communication skills... Communication is always a one-way street. ——Alternating current is direct current. Fortunately, there seems to be no problem with physical strength and mobility, but it's still a bit too strong...? I hope to create a work with a low-magic worldview, rich wit, and interesting characters.
