Chapter 172 The Witty Li Nan Di

• After hanging up the phone, Cheng Yuan planned to pass the red pill to Doctor Xu for a laboratory testing before letting Bai An Xiang take it.
• Since the source of the pill was unknown, as the man in glasses said, their boss did not trust Cheng Yuan, so naturally Cheng Yuan would not trust him too.
• He went to Doctor Xu’s clinic and found out he was not there, the nurse told him that Doctor Xu was in the dean’s office.
