Zhang Lisheng's last sentence sounded like a curse; Xu Naijia could not help but frown after hearing this. "Dr. Zhang, other than being a Father, do you have a part-time job in being an astrologer or a prophet as well? Futile cursing is the most incompetent performance of a man; I hope you have some self respect for yourself."
Zhang Lisheng smiled and suddenly asked, "Dr. Xu, I believe you must not have majored in biology at a university, right?"
"My Ph.D. is in Environmental Science at the University of Cambridge in England, and I've made cross-disciplinary research on biology before. Is there any problem?" Xu Naijia asked.
