"Datou must be joking with Dad," Nie Tianqin wasn't worried at all.
Seeing Nie Tianqin's certainty, Nie Guangyi tugged at the corner of his mouth with a smile and deliberately asked, "How can you be sure?"
"A father's intuition," Nie Tianqin responded without hesitation.
"Is that it?" Nie Guangyi was obviously not very satisfied with that answer.
"Because my son is a genius. He has had an exceptional memory since he was young. Once he remembers something, there is absolutely no way he would forget it," Nie Tianqin offered another explanation.
"Hmm," Nie Guangyi nodded in satisfaction, "Professor Nie makes a valid point."
"Datou, quickly tell Dad how we can solve this once and for all."
