Hearing Shao Yao's words, the old man Gu Cao also had a skeptical face, and said to Shao Yao: "Little girl, even if you are angry for me, you shouldn't say that the medicinal plant is fake, in my opinion, this is a keel root that is unmistakable." ”

"That's it, you little girl can't compete with me in bidding, so let's talk nonsense. The rich man also looked at Shao Yao with contempt.

Shao Yao didn't refute, just said calmly: "It's true that this is very much like the roots of a 10,000-year-old keel tree that naturally shed, but everyone is most likely to ignore the fluff at the tip of the keel root. ”

"This ······ What does this mean, I must be a dragon bone root, and I can't be wrong!" the vendor said excitedly to Shao Yao.

"Don't get excited. Shao Yao smiled slightly: "Presumably, the old man Gucao also explained to you the basic medicinal properties of the keel root, then the most obvious place to show the medicinal properties is the roots, if you want to prove whether this is a real keel root, you only need to break the next section slightly, if it drips pure cyan mucus, it means that it is an excellent quality keel root, if there is no liquid flowing out of the truncated place, and it shows the characteristics of pan-drying, then I can estimate that this is the root of the ridge grass tree." ”

"That's right, why didn't I think of this, the roots of the ridge grass tree are very similar to the root of the keel, but because it is not used in medicine, it does not appear in the market of medicinal plants at all, and the root of the dragon bone is extremely rare, and there are very few people who know how to distinguish it. The old man Gu Cao's eyes lit up, patted his head and said.

"I ······ Why should I believe you!" After listening to Shao Yao's analysis, the rich man was also a little flustered, the medicinal plant that he bought at a great price turned out to be a fake, so he didn't lose a lot, the key is that this little girl's description is too detailed, and she looks like a person who understands medicine.

Shao Yao walked up to the rich man and said slowly: "Then you can break a section and try it, this section will not affect its medicinal properties at all, and generally speaking, refining the pill does not have much demand for the dragon bone root, such a large plant will definitely have a surplus, you can rest assured." ”

The rich man glanced at Shao Yao suspiciously, and then looked at the vendor, seeing that the vendor was in a cold sweat on his forehead, and he smiled at the rich man: "Don't believe this kind of little girl, she is cheating on you, if you break off a section, won't you lose it, you believe me, this is absolutely true." ”

After hearing this, the rich man straightened up and looked at Shao Yao: "Hmph, little girl, don't think that you know a little knowledge and be arrogant, today I will let you see what the real dragon bone root is." Then in front of Shao Yao, he broke off a small section of the root of the keel. However, the expected pure blue liquid did not flow out, only a dry section, nakedly announcing the truth and falsehood.

"You!" the rich man pointed at the vendor, furious.

The peddler knelt down tremblingly: "This lord spares his life, I am both old and young, and I don't mean to sell fakes······"

Before the hawker finished speaking, he was kicked away by the rich man, and he was also aggrieved by eating, if he didn't rob the old man's medicinal plants, he wouldn't buy fake medicine!

Seeing the reaction in front of him, it was all expected by Shao Yao, and then he looked at Old Man Gu Cao: "Old Man Gu Cao, I'm tired of stretching out your hand." ”

The old man of Gucao stared at Shao Yao with bright eyes, this little girl not only has the discerning eye to know the Dan furnace, she is humble and not afraid of things, but she is also so proficient in medicinal plants, she has found a treasure, and she was stunned when she heard Shao Yao's words: "What is this?"

Shao Yao stared at the old man Gu Cao and frowned: "Senior, you are poisoned, but you want to refine the Anti-Yuan Retrospective Pill?" ”

"You, how do you know!" The old man Gu Cao was shocked after hearing this, and he couldn't help but stretch out his hand, this little girl is too godly, so she can see that she is poisoned?
