Zhou Shaoping's heart leapt with joy, and he whispered, "One more thing is missing, it's got to be six kinds of herbs in the Liuwei Dihuang Pills."
Master Chen suddenly waved his hand, "No, it's not mountain yuri, it's wine-processed mountain yuri."
He opened his eyes, and Zhou Shaoping frowned, "Is there still one more that you can't identify?"
Master Chen shook his head, "I could only identify five kinds of herbs."
Zhou Shaoping urged, "Think carefully again."
Master Chen took a bit more powder and put it in his mouth. He tasted it for a long time but still shook his head.
Zhou Shaoping snorted, "You better not be deceiving me."
"Your tongue is so adept, and yet there's a herb you can't recognize?"
Master Chen suddenly said, "Could it be yam? I tasted a slight hint of sweetness."
Yam has no significant aroma and only a faint, almost undetectable sweetness when eaten; tasteless things are naturally hard to identify.
Zhou Shaoping slapped his thigh, "It must be yam."
