Chief Jiang once again confirmed that Zheng Ren was not joking. He walked to the operating table in confusion and looked at Zheng Ren. He asked, "Doctor Zheng? What's wrong?""Have you ever had a heart attack before?""Yes but that was a long time ago. There's nothing abnormal now.""Lie down. Slowly. Don't use too much force." Zheng Ren's words were filled with authority and could not be rejected.Su Yun looked at Zheng Ren in surprise. He couldn't have really diagnosed Chief Jiang as having an acute myocardial infarction, right?Chief Jiang was stunned. He did not spend much time with Zheng Ren but Zheng Ren had long conquered him with his unparalleled surgical techniques.What he was saying was all true...He laid on the operating table in a daze and smiled. "Doctor Zheng, you should seize the time to rest for a few hours."Chief Jiang thought that Zheng Ren's behavior was abnormal because he was tired. He should not anger him now.
