Ye Tian Yun was currently relentlessly combing his hair to generate something called 'friction', which would then help in the flow of 'charge'.
To Ye Tian Yun, words like friction and charge were alien. If not for System, he may have never heard or understood a different meaning of these words.
Before today, the only other meaning that he thought of charge was to attack or charge at enemies.
As for friction, Ye Tian Yun had never used this word; thus, it was more of a new term for him.
His current goal was to generate a spark of lightning. But this didn't seem like an easy task to him.
After all, how is it possible to create lightning from a comb? This was unheard of.
But on System's insistence, Ye Tian Yun began to concentrate on this task and combed his hair, softly and swiftly.
The System had told him to wait till a certain point when taking the comb close to the hair, but not touching them would make the hairs move.
