Pan Long wasn't surprised to see the two of them go. They had both attended his advanced mathematics lesson back then and come away so dazed they could barely think straight. His teacher might forget the pain, but they remembered it.
Then he began discussing the nature of electricity with Bi Lingkong.
As it turned out, Bi Lingkong really had studied it. Since becoming one of the Immortals and Buddhas, she had acquired powers related to electricity and gained a much deeper understanding of its nature.
