"Oh, then you go ahead and be busy," Ding Xiaoyou said, ready to hang up the phone.
At this moment, Professor Yang Kaining said, "Principal Ding, if your sister has something important, it shouldn't be delayed either."
After all, they had discussed almost everything that needed to be discussed, and Professor Yang Kaining didn't want to be the reason Principal Ding was held up from attending to her sister's matters.
Moreover, as far as Professor Yang Kaining knew, Principal Ding's sister was an incredible genius.
Even calling her a genius seemed somewhat insufficient.
"Xiao You, go on, what is it?" Ding Yue asked, "I'm not busy now, anyway."
"Hee hee hee, I made a special graphene battery for Big White, want to try it out?"
An excited Ding Xiaoyou said from the other end of the phone.
"Oh?"
On hearing this, Ding Yue's eyes lit up, and he said, "Sure."
