Sun Hancheng said with a slight smile: "In Africa, there is an animal called the iron badger with thorns all over its body, if someone or an animal wants to attack him, he will form a ball and erect the thorns on his body to attack the enemy, this thorn is empty in the middle, there are holes, but it is very hard, and there is a substance on this thorn that can treat gingivitis, and it is very good to use to make toothpicks." ”

After Sun Hancheng finished speaking, he looked at Lu Chengxuan, Lu Chengxuan was very surprised, he couldn't have imagined that Sun Hancheng would even say the material of this toothpick.

But he didn't say much, picked up the wine glass and drank the wine in the glass, still his face did not change.

Those teachers at Nanjiang University also didn't expect that Sun Hancheng would be able to guess two toothpicks correctly in a row, you must know that even they can't guess it.

Lu Chengxuan didn't care at all, because only he knew how rare the material of these toothpicks was, ordinary people couldn't distinguish one at all, although Sun Hancheng could distinguish two, he wasn't too surprised.

Since you can be a teacher at Nanjiang Normal University, it is impossible if you don't have some real skills.

So he immediately took out the third toothpick, put it on the table, and gently turned the turntable on the table, and the toothpick was handed to Sun Hancheng.

This toothpick is red all over the body, with gold inside, and some black, the whole toothpick is like a work of art, which makes people have an idea when they see it, that is, who can be willing to use such a toothpick to pick their teeth is simply a waste.

Everyone at Nanjiang University looked at Sun Hancheng with a smile, they all knew that the material of these toothpicks was becoming more and more difficult to identify, and this one looked like it was wooden, and it was the core material of wood.

A lot of mahogany furniture can be seen just by relying on the pattern on the wood to see what kind of wood is made, but the core material of the wood is different, there are few patterns on it and the color is not much different, plus it is made into a toothpick as thin as a needle, it is too difficult to guess.

Professor Ge and the others naturally understood such a truth, so their eyes were full of surprise and stunned, and they were all worried about Sun Hancheng, although losing was just a glass of wine, but now this situation is not as simple as a glass of wine.

This is clearly Nanjiang University shouting at Nanjiang Normal University, and this Lu Chengxuan is really very insidious, giving others a feeling of getting more and more difficult according to the order in which he took the toothpick just now.

There are a total of eight roots, and if Sun Hancheng guesses the third one wrong, it is enough to show that Sun Hancheng's skills are nothing more than that.

But who can know if this one is the most difficult one to guess, in the impression of others, this one can only be regarded as the third most difficult one, this is where Lu Chengxuan is insidious.

Sun Hancheng was also slightly stunned, this thing is really not easy to guess, and this wood is obviously often played with, and there is some pulp on the toothpick, which increases the difficulty of identifying this toothpick.

Sun Hancheng took a look at which toothpick he was holding, looked at it very carefully, and even put it in front of his eyes.

"How's it going, can't you see it?"

Zhu Zhang of Nanjiang University smiled slightly, he can be regarded as half of Lu Chengxuan's master, and he was naturally very happy that Sun Hancheng of Nanjiang Normal University took out something like him.

Sun Hancheng smiled a little embarrassedly at this famous expert and said, "This thing is really unrecognizable, and there are no big features of such a thing, and there are no less than twenty kinds of trees similar to it. ”

Hearing his words, many people laughed, Zhu Zhang smiled slightly and said: "Of course this thing is not easy to guess, and it doesn't take advantage of you, otherwise it will be like this, I will also add some color, if you guess correctly, I will also make a big cup." ”

As soon as Zhu Zhang's words were finished, those who would be in the university bet one after another: "I will also add, if you say it accurately, I will also have a drink." ”

Even Wei Jin, the president of Nanjiang University, saw that the other teachers said this, and he didn't want to participate in this matter, so he had to fill the wine glass in front of him to show his attitude.

Sun Hancheng pretended to be embarrassed and said: "It's really embarrassing for me to do this, you all added, do you let me guess the wrong two cups?"

As soon as Sun Hancheng finished saying this, everyone immediately looked at each other, and the people of Nanjiang Normal University were even very surprised, I don't know why Sun Hancheng would add a cup to himself, originally no one would blame him if he didn't speak.

The people of Nanjiang University were happy in their hearts, and they all felt that their agitation method had worked, if Sun Hancheng guessed wrong this time, he would drink two cups directly, which would be the same as Lu Chengxuan.

But at this time, Sun Hancheng looked at Lu Chengxuan and didn't speak casually, but Lu Chengxuan naturally understood what Sun Hancheng meant, and said with a smile: "Okay, if you guess right this time, I will accompany you to drink two glasses." ”

Now it was the turn of the teacher at Nanjiang University to be surprised, this Lu Chengxuan is a little too strong in everything, and he will never be left behind, even if he is confident in his toothpick, he should not add it at this time.

Sun Hancheng just smiled after hearing this, didn't say anything, looked at the toothpick again, picked it up and knocked it lightly on a teacup, the toothpick hit the porcelain cup, and there was a metal knocking sound, obviously this small toothpick is very hard.

He handed the toothpick to Li Aiguo, who was already eager to try it beside him, but after Li Aiguo received it, he hurriedly handed it to Minister Wang next to him without looking at it.

Minister Wang and Director Zhao were also surprised after reading it, and obviously felt that it was really difficult for such a small needle-like wood to guess what kind of tree it came from.

At this time, Sun Hancheng pretended to be very embarrassed and said: "The material of this thing is very hard and has pulp, although it is a tree, it must also be a very valuable tree, but what kind of tree is it?"

Hearing Sun Hancheng's words, the people from Nanjiang University became a little impatient, and said: "Do you know or not, just say if you know, and drink so much nonsense if you don't know." ”

Sun Hancheng smiled and said, "Don't worry, you have to let me analyze it carefully." ”

He pretended to be pacing in place, as if he was thinking seriously, and said to himself: "This thing, it should not be very old, it should be something from the last ten or twenty years, a bit like mahogany, I guess it should be green sandalwood and red sandalwood." ”

Sun Hancheng looked at Lu Chengxuan when he said this, in fact, it was not only Sun Hancheng, many people looked at Lu Chengxuan, wanting to see the expression on his face. Analyze what Sun Hancheng guessed.

But Lu Chengxuan's face didn't have any expression, and he couldn't see any waves, but there was a smile on Zhu Zhang's face at Nanjiang University, with a sarcastic look in his smile.

Sun Hancheng just paused, and then continued: "No, it shouldn't be green sandalwood, red sandalwood, or mahogany, this wood is much harder than mahogany, and the knocking sound just now seems to be iron." ”

He suddenly said with some surprise: "I know, there is a very hard tree in the bitter cold land of our northeast Heilongjiang and other north, this kind of tree is called the iron plough tree, which can reach twice the hardness of steel, I guess this toothpick is made of the iron plough tree." ”

After Sun Hancheng's words were finished, many people looked at each other, wondering if there was a tree in the world that was harder than iron, why hadn't they heard it.

But just when they questioned whether the tree that Sun Hancheng said existed, they saw that the faces of several people from Nanjiang University had changed, and their eyes were full of surprise when they looked at each other.

Sun Hancheng asked indifferently, "Did I guess right?"

Lu Chengxuan seemed to understand, and said with a look of anger on his face: "You should have guessed it before, right, deliberately let us all add a glass of wine." ”

Lu Chengxuan was questioning Sun Hancheng, but was stopped by Wei Jin, who was raising his glass, and said: "What are you talking about so much, since Teacher Sun has guessed it, then it's better to drink." ”

Wei Jin obviously knew that it was too late to say anything at this time, and he would be said to be unreasonable, so after speaking, Wei Jin first took the wine in front of him and drank it all, the principal spoke, and the other teachers of Nanjiang University naturally couldn't say anything, and they all drank the wine in front of him.

Pity Lu Chengxuan, he has already drunk two glasses before, and this time he has to drink two glasses in a row. This glass of liquor is two taels smaller, and if you drink four glasses, it will be seven taels to eight taels.

After drinking slowly for a few hours, you may be able to drink it, how can ordinary people withstand this kind of drinking, which is why Lu Chengxuan was angry just now.

But Wei Jin has spoken, and the wine has already been drunk, even if it is uncomfortable, he has to force himself to drink it.

After drinking two glasses of wine, Lu Chengxuan's face was flushed, obviously he was already overwhelmed by alcohol, but he still held on.

Sun Hancheng said with concern: "It's okay, I see that I'm almost drunk, so be it." ”

"No, I haven't guessed yet. Lu Chengxuan took advantage of the strength of the wine and his stubborn temper to come up.

If things are like this, Lu Chengxuan will definitely not be able to drink it, but no one stopped it, Minister Wang and the others still looked at the two groups of people on the wine table with interest, as if they did not see the situation on the table.

Zhang Yun and Li Aiguo from Nanjiang Normal University saw that Sun Hancheng had steadily suppressed Lu Chengxuan, and he liked to see this situation very much, so he naturally didn't bother to stop it.

And the people of Nanjiang University still have hope for Lu Chengxuan, they have already suffered a big loss just now, and they have lost face in front of Minister Wang, Director Zhao and others, so they naturally hope to get this face back.

This is a kind of gambler's mentality, after losing, they want to be able to turn over and win back, so no one wants to take the initiative to back down at this time.

Another reason is that they are very confident in this small box of toothpicks, Lu Chengxuan once showed them in front of them when he first got these things, even if they couldn't recognize them all with the help of some tools.
