Looking at his expression, Li Zhi felt the urge to curse.
"Do you know why Farady was born before you?"
"Why?" Shen Yuan asked instinctively.
"The sight of you would make him die of anger."
Shen Yuan gave a sheepish smile, but before he could speak, Li Zhi jabbed the test paper sharply with her pen.
"Look here! Why are you looking at me? We're talking about electric fields, and trust me, there's no electricity between us right now."
"Oh."
Shen Yuan meekly ducked his head and focused his attention on Li Zhi's pen.
As Li Zhi explained, one moment Shen Yuan's brow would be tightly furrowed, and the next he'd be sucking in a sharp breath.
As for Li Zhi, all she was left with was stress.
"The furrows on your brow are more accurate than the electron trajectories you're drawing."
"Are you sucking in all that cold air? Trying to freeze your brain?"
