"I don't know what he knows, I think it's just ordinary pig iron that is not forged. Nowadays, war is of little use, but it is called the mother of metals, and it is one of the earliest metals known to mankind. The scientific name is iron, and it is also a combination of many metal materials. Until now, many metals have been called iron when they are named, just like meteorite iron. In fact, many metals have no resemblance to iron, and they will also be called iron. And it is also an essential raw material for materials such as steel. ”

Hearing Su Xuan's answer, the people outside were very surprised. They were the same as the young man's guesses. Don't forget that this is the assessment of a third-level mechanic, how can there be such an easy question, so the first answer that comes to everyone's mind is Dart meteorite metal.

In fact, when he first saw this metal, Su Xuan also thought that it was Dart meteorite metal. But just as he was about to write, he suddenly remembered something, and it was something that happened when he was a Moqiu star.

Su Xuan was originally a garbage picker, and in the hull of a large warship, his harvest was very low. The old man was there at the time. But he was different from Su Xuan, he was smiling and scraping some metal powder on top of some metal. And not only that, but he also saw that the old man was very interested in some black metal, something similar to a button.

The old man told him that it was Dart Meteorite Iron. And I told him about some features. This kind of thing is used as a coating material because it has few uses. It is mainly used for factors such as the weapon will not reflect light, isolate the interference of special signals to the weapon, and so on. Not because it has fewer uses, but because it is more popular, and can easily be replaced by other, cheaper metals, or equipment.

Listening to the old man, this metal is more suitable for the use of special weapons, as for what is the use, the old man did not say, the old man always said that he did not like to build weapons and equipment, and he did not teach Su Xuan to let Su Xuan repair a pulse cannon It would take a few days, of course, the main reason was that he was not a mechanic at that time.

Although he didn't know much about this metal, he had heard the old man say that this metal was a metal that had been dusted for a long time. In fact, its role has been underestimated by everyone. Since the old man has said so, there is no reason why the mechanic union is such a big force not to know this. If it is really underestimated, it will definitely not appear in the third-level metal assessment. Even if there was one before, but after knowing that it was wrong, it would definitely be corrected. That's the rule.

On the third-level guessing metal assessment, only C-grade metals are allowed, as well as grades below C-grade metals, and even the small amounts of B-grade metals that Su Xuan encountered when picking up garbage before will not appear. Although Su Xuan only got a little bit of these metals, many people who picked up garbage also relied on luck. Just like Zhang Feng, he just sees something and takes it away when he feels it's valuable. And I've been in the garbage star for a long time, even if I don't know what those metals are, but I can estimate whether they are worth anything.

But Su Xuan had the help of the old man, and Su Xuan also wanted to know the true value and name of those metals, in addition to wanting to sell them for a good price, just to suppress those subordinates. So he always showed the old man the metals he didn't know, and then the old man lazily told him about the properties of metals.

Although Su Xuan didn't know much about the metal knowledge he had learned, and he had almost never seen the advanced ones. But like the previous nine, Su Xuan has seen a lot in the garbage star field, and there is no pressure at all. If only the types of metals he saw, Su Xuan knew no less than them, but much more.

So this is just a reason for him to guess that this tenth metal cannot be Dart's meteorite metal, because that metal, which was originally a B-grade metal, has surpassed C-grade metal. People don't think about why it appears here, they just think it's low use, so it's here. But the old man said that if it was of a higher level, it would not be possible to appear here.

There is another reason, many people know that it can be used as a coating material, and that is because this metal can resist the interference of enemy electronic warfare. In fact, it has another role that has been overlooked, that is, it is not reflective in any case. This is one of its more popular roles, because there are a lot of non-reflective coating materials, mainly black. So no one cares about it. I don't even know what it does.

But the metal one in the picture was taken in the sunlight. It may be to give people a hint, so the reflection is very obvious. If the surface of pig iron is smooth, the reflection is also very obvious. Moreover, pig iron is also a material below grade C metal, which fully meets the rules of guessing metal. Su Xuan really couldn't think of any other metal that could be so similar to Dart Metal. Dart metal appeared early, but it was discovered late, because everyone used to treat it as pig iron. And it has the same melting point as pig iron.

"Pig iron! You're not kidding. This is the place where the third-level mechanic is examined, how can a metal like that lowest grade appear here. Do you think the Level 3 assessment is so simple? A metal like Dart, if you haven't seen it, should be, after all, the number of occurrences is relatively low. I'll go back and read more books on metals. ”

The young man looked at Su Xuan with contempt, and the old man Qiu's junior brother outside also laughed. Because he thinks that this game his disciple won. And Old Man Qiu was also a little regretful, but he didn't blame Su Xuan, he also knew that Su Xuan was trying his best to help him, but maybe Su Xuan didn't know about this metal.

Even the people who assessed it thought that Su Xuan had guessed wrong. Because the question was not given by him, but assigned by the general control system of the mechanic union, he not only did not know the answer, but also could not affect the content of the assessment. But the two people have different answers, and he still needs to announce the answers.

But when he saw the answer given by Zhi Brain, he himself was dumbfounded, and the rest of the people were also dumbfounded, only Su Xuan breathed a sigh of relief, because the answer given was unforged pig iron. If the forging is complete, almost any mechanic can guess it.

"How is it possible, how is it possible. It's Dart, how could it be turned into pig iron. There must be something wrong with the system. The young man couldn't help but growl. I can't help but wonder if the intelligent system of the mechanics' union is different. This intelligent system is many times more advanced than Su Xuan's intelligent brain, and it has been with the mechanic union for countless years, how can it be a mistake of the system.

It's about doubting the system, it's about doubting the fairness of the mechanics' union. Therefore, those who were assessed looked at the young man with unkind faces. Even his master didn't know how to speak for him.

"You're saying that the mechanic union is shielding that Su Xuan."

Suddenly, an indifferent voice sounded, and an old man suddenly appeared in the hall. It appeared very suddenly, and when everyone reacted, those who were assessed immediately bent down and said respectfully, "Vice President."

It turned out that this old man who suddenly appeared was one of the three vice presidents of the mechanic union. Because of the mechanic of Huaxia Mechanical College, he was sent over and sat in the Guangxing Domain. He rarely shows up, and usually asks the dean of the mechanical academy for advice. Although he is only at the peak level of a mechanical master, his status is special, he is one of the apprentices of the Normanche mechanical master.

So even the dean, I have to give him a little face. Moreover, the dean is also the honorary president of the mechanic union, and almost all the mechanical masters are the honorary presidents of the mechanic union. They only enjoy privileges, they don't have to contribute, and the mechanics' guild is just using their name.

He actually said such a thing, which shows what kind of atmosphere the old man is at this time.

The young man also realized that he had said the wrong thing, his mind was very flexible, and there was still a lot of great wisdom without small cleverness, otherwise he would not be able to please his teacher. So he immediately knelt down and begged for mercy and said, "Lord, spare my life, boy, I just didn't do it unintentionally." And. There is no meaning to look down on the mechanics' union at all. ”

"Humph!"

The vice president snorted coldly, and the young man only felt a tightness in his chest, and then spit out a mouthful of blood. He is just giving the young man some punishment, and he can't get along with a young man, after all, he is also a person with status. If you are entangled with a junior, you will lose your value a bit.

And the other party is indeed not guilty of death, if the people who have some ideas about the mechanic union are killed, then how many people need to be killed, and the mechanic union does not have that strength. It's just that the young man said it in front of him, which made him feel unhappy.

Many people only think that he is a mechanic, and he is one of the vice presidents of the mechanic union, don't forget that he has another identity, that is, he himself is an old monster-level powerhouse, which is the so-called saint-level. Just take the way you just appeared, you can calm a lot of people.

But he can't bully juniors either. Whether in the realm or at the mechanic level, the people here are his juniors. So he was too domineering, and it was inevitable that no one would make irresponsible remarks, so he said: "This is pig iron, which is the topic I set myself." Nobody says pig iron can't be here. ”

As he spoke, the old man took out a piece of iron, which was exactly the same as in the photo. If you were a little skeptical just now, you don't have any doubts now. A master who has been famous for a long time, and he is also a person with saint-level strength, it is impossible to deceive these juniors. And he said very clearly that he came up with this question, and the intelligent brain system also gave the answer, so everyone has nothing to doubt.

The old man didn't care about everyone's reaction, but turned his gaze to Su Xuan, who had a calm face. Don't look at Su Xuan's confident look, seeing such a senior, he can still deal with it calmly. In fact, he is also playing drums in his heart, and he is also nervous to death. But he can still hold back his excitement, probably because the old man has nurtured him for a long time, so that he is not as excited as others.
