Looking at Su Xuan's performance, the old man was also very satisfied. looked at Su Xuan one level higher.

"How do you know it's pig iron, not Dart metal. It can't really be guessed casually if you don't know, right? Seeing Su Xuan's performance of neither being humble nor arrogant, the old man did not continue to put pressure on him, but spoke. Otherwise, Su Xuan wouldn't be able to hold out for long.

The old man didn't put pressure on him, and Su Xuan himself breathed a sigh of relief. Hearing the other party's inquiry, it was impossible for him to say that when he was studying with his master, the old man said that the grade of this metal was better, and it was impossible to appear in such an assessment. First of all, not to mention whether this reason can convince this person, and secondly, his mentor is here, at least temporarily, otherwise it will be exposed.

So he said the second reason, "Don't hide it from the seniors, at the beginning, the juniors also thought it was Dart Metal." However, the younger generation clearly remembers that Dart metal has a very popular feature, that is, it is not reflective, that is, it cannot see the metallic luster. And Dart also said that when he discovered this meteorite metal, he also discovered it because it was not reflective. However, when this metal is shot, there is a noticeable metallic luster, which is called reflection. So the junior directly deleted it from Dart Metal. ”

When he said this, the rest of the assessors, as well as Old Man Qiu's junior disciples, all whispered.

"Is what he said true? Is Dart Metal really not reflective? ”

"I don't really know, but there are a lot of metals that don't reflect. Because there are alternatives to this feature, I didn't pay attention to it either. I'll check. Sure enough, there is this, you see, you see, this is one of its popular characteristics, and I haven't paid attention to it before. It is clearly recorded above that this metal has no metallic luster, which is a miscalculation! There are so many metals, who is idle and has nothing to do, and look at the mass characteristics of each metal. I guess I can't finish watching it for a thousand years? ”

……

That person is right, there are a lot of metals in the universe, and when everyone looks at metal, they like to look at its characteristics, which is more conducive to the use of metal. As for the mass characteristics, you just need to search and find a good and inexpensive metal. And Dart metal is so expensive, as for the metal without metallic luster, there are a lot of this, some steel and plastic have it, and it can be completely replaced, so there is no need, no one has to study it. Su Xuan also encountered it once because of his specialness, and it was the old man who explained it to him, otherwise he didn't know that Dart Metal still had such a feature.

I only heard Su Xuan continue to analyze: "The junior has been thinking about it for a long time. There are very few metals that meet the requirements of the picture. The younger generation also thought about whether it was a change of color or something, or the reason for the photo. But I don't think it's possible, so there's no need to bother. Therefore, the younger generation has limited knowledge and only thinks of pig iron.

At first, it was too easy to guess. But whether it's density, shape, color. As well as the degree of reflection, it is very similar to pig iron. So the younger generation took the risk of guessing that this is pig iron. And to be felt, there is really no regulation, guess the metal, can't there be pig iron? And there are no violations. I made up my mind. ”

The vice president smiled and said, "You observed very carefully, and you guessed it. It's been more than 300 years since this question was asked, but no one has ever guessed it, and you're the first to guess it. Although the problem is very simple, everyone always likes to complicate simple problems, so that they do not solve the problem, but find the problem for themselves. I don't praise you because you guessed correctly, because there are many, many people who can guess this question, but you are the one who dares to say it. Many people guess correctly, but they deny themselves, and even you don't have confidence, how can you guess this question. It's like doing things, if you don't have the confidence to do it well, how can you succeed. That's why I admire you. ”

None of the people below spoke, and they all felt that the vice president's words meant something else, as if they were warning everyone about something. It's a bit esoteric, but you can only listen carefully.

"Well, as the first person to guess this question, I'll give you some reward. After all, I came up with the problem. Originally, it was just a child's play, but I didn't expect it to stump many people for 300 years, which can be regarded as an unexpected gain. Since everyone is guessing that it is Dart Metal, then I will give you Dart Metal. Here is a hundred kilograms of Dart metal, which is considered a reward for you, and I hope you can continue to work hard. ”

Hear this. Su Xuan was very excited, and immediately bent down to thank him.

That young man hated Su Xuan so much now, he thought that all this was because of Su Xuan, if it weren't for Su Xuan, he wouldn't have been so out of shape, let alone make the vice president angry. Now he has Dart Metal again, he has seen it from the virtual network, but he has not seen the real thing, and now he is very jealous.

He didn't dare to have any dissatisfaction with the old man, probably because of the difference in status, so he couldn't mention it, and he didn't even dare to have any dissatisfaction.

The old man didn't stay in this place for long, and although Su Xuan performed well, it only proved that he was more careful. If you want to become a genius, there is still a long way to go, and the reason why he appeared was because Su Xuan guessed this question that no one had guessed for a long time, but not because of how much attention he attached to Su Xuan. So I stayed here for a while, said a few words and left.

Don't think that there are only ten metal guessing questions in the third-level assessment, in fact, there are a lot of them. It is also very difficult to fully master those metals, but every ten is a level, that is, it is more difficult, the hundredth thing is the last, and there can only be three wrong answers at most. That is, there are three chances. The answer to the tenth question this time gave Su Xuan a little advantage.

"Nickel iron, a rare metal. One of the originals of nuclear weapons, the crisis is enormous. Explosive, unstable. Not suitable for use with metal materials. It used to be ranked above Grade B metal, but it was removed from the metal ranks. But thousands of years ago, a scientist proved that this metal existed. So it was included in the ranks of metals. But there are still many people who don't admit it. Temporarily pacify non-C-grade metals. ”

Next, the speed of the two of them answering the questions was much faster, but the young man did not provoke Su Xuan again, when the hundred questions were over, Su Xuan only had one question that was not answered, and he barely passed the third-level mechanic assessment. But the young man was more unlucky. His strength is still good, and he should also be about a third-level mechanic. But he lost to Su Xuan in the pig iron level, and in the subsequent competition, he answered three questions incorrectly. As a result, there were four wrong questions, so I failed the assessment.

Old man Qiu's junior brother's face turned green, and he gritted his teeth with hatred. If he chooses a decent assessment according to normal strength, his disciple will pass. Or if the pig iron is replaced, his disciples will be able to pass. But he was mean by nature and wanted to humiliate his senior brother, so he wanted them to compete. And the best way to compete is to guess the metal.

Even when he himself was watching below, there were two more who he didn't know, and he had never participated, and he didn't prepare these when he came, so it was good to let his apprentice go into battle in a hurry. But this decision can be regarded as harming his apprentice.

The mechanic union has a rule that after seeing a failure, you must take another year before you can come to the assessment again. If it still fails, it will have to be two years apart, and so on. If it is voluntarily waived, this provision does not count. But if you give up before the assessment after you come, then it will be regarded as a failure and you will have to wait for an extra year.

This is also the reason why Old Man Qiu said that he would rather hide his identity than let Su Xuan leave, saying that it was because of the provisions of this article that Su Xuan was delayed for a year. At this time, the young man, because he failed the assessment, it would take a year to come to the assessment again.

"Useless waste."

After the young man came down, before he could speak, he was slapped by the angry old man Qiu's junior brother. But after the draw, he regretted it, and he remembered the identity problem. When he came, he told Old Man Qiu that he was now a mentor to some young masters of the family, and this young man was also one of the young masters of the family. This slap can be regarded as offending the other party.

But for a mean person who wants to have a face, he will not bow his head and admit his mistakes. He knew that he had offended another family this time, and he was very annoyed in his heart, and he didn't pay attention to the young man who had already left, he attributed all this to his senior brother and his apprentice.

There are so many people here, he is embarrassed to stay here longer, and raised his hand to say a cruel word, but seeing that the rest of the people have such a good relationship with Old Man Qiu, he didn't say anything, turned his head and left here.

"Congratulations to Elder Qiu, congratulations on accepting such a good apprentice."

The rest of the people also stepped forward to congratulate, judging from Su Xuan's age, he can be regarded as a little genius, after all, everyone has worked together for so long, although they are a little envious, but they are still happy for Qiu Lao.

Although they work together for the union, they do not belong to the competitive relationship, they all rely on their own efforts and talents, and they can go up if they have the ability and go down if they are not, so there is no grudge between them. It's not like those people in the company, because they are in a competitive relationship, it's normal to calculate each other.

Old man Qiu breathed a big sigh of relief this time, and he was also very happy, and he was inevitably polite to the congratulations of the old friends around him.

Su Xuan also came down from above and walked next to the old man, and he also smiled at the praise of everyone around him. Su Xuan didn't take anything about offending Senior Brother Qiu. He didn't worry about the retaliation of those two people, because he would leave after the assessment, and there was no need to worry about these things. When he returns to Qingfeng Adventure Academy, those two people may not be able to find him.
