Round six of the game, Zheng Chunhua meets Qin Cheng again.
"How's the situation on the patient's side?" Zheng Chunhua asked.
Qin Cheng answered truthfully: "There's one Infected, but fortunately, the other patients are quite cautious, so he hasn't infected more people.
"I sold him three tablets from the previous bottle of M-class painkillers, taking one per round is enough to cure.
"So currently, the patients in Zone D should be safe.
"How about your side?"
Zheng Chunhua said: "I got three more bottles of M-class drugs, two unopened and one opened.
"I can roughly determine the price for M-class drugs is around 1400, while the other three types are indeed much cheaper.
"And... Chen Guangming doesn't plan to sell me any M-class drugs."
Zheng Chunhua briefly recounted the situation when he met Chen Guangming and Bai Zilan in the previous rounds.
