"At first, I just wanted to feel that sensation again, so I began allowing myself to be hit by lightning. Ah, don't give me that look, I took proper precautions and even had potions nearby," He placated Rui who furrowed his eyebrows when he heard of what Kane had been doing. "I soon discovered that my senses and nerves grew kinda super jumpy at everything. Like, I would overreact to simple stuff like thunder."

He paused for a moment, before continuing. "The jumpiness disappeared after some time, but the more I did this, the longer it lasted. So for the first month, I just subjected my body to lightning and… just did that and nothing but that."

Rui's expression had already morphed considerably, conveying what he thought about all of this.

"Okay, but hear me out Rui," Kane gestured with his hands before him. "By the time the second month came, the pain was minimal. I found that when I did it bare-footed, it didn't hurt at all!"

Rui's eyes widened.

That shouldn't be possible!
