"Mentor! I would like to continue to take the Level 4 Mechanic exam. ”

When everyone calmed down a lot, Su Xuan spoke again. His words shocked everyone more than becoming a third-level mechanic.

Don't forget, Old Man Qiu is so old, he is also a seventh-level mechanic. If Su Xuan became a fourth-level mechanic, it would indeed be very remarkable, so everyone was very surprised.

Old man Qiu only remembered at this time that Yang Shaofeng came here to become a fourth-level mechanic. Because of Su Xuan's reason this time, he finally breathed a sigh of relief, so he still had a very good impression of Su Xuan, so he thought for a while and said: "It's a good thing that you have confidence, not this time, there will be a chance next year." Have you decided which assessment method to choose? ”

Su Xuan nodded seriously, and finally chose to repair it. In fact, he can choose to assemble it, but that is the content of the fifth-level mechanic assessment, and if he chooses it now, it is indeed a bit scary. Moreover, he has not yet developed his own mecha, and even if he passes the assessment, his own strength has not reached that level.

Thinking about these clearly, Su Xuan decisively chose the assessment of the first level of assembly, that is, maintenance.

The mechanical maintenance assessment is carried out in a virtual environment, and the mechs repaired are also random. There are a lot of materials that can be virtualized in it, and it feels the same as in the real world. It's currently three hours, and the repair of the mecha is considered successful, and there are also drawings for the damaged part, which is also to let everyone get in touch with the drawings, and they can be used when they reach level five.

Su Xuan took a general look and found that this mecha was a very old-fashioned mecha that still used a turbine engine. The mecha made of this engine is very large and very slow. But there is an advantage, that is, it has a high load capacity, it is a small arsenal, but it can achieve effective fire suppression.

This is also the reason why this mecha is very backward and is still used in large numbers in all empires. Because of the heavy load, it is difficult to replace other mechas. And this kind of mecha is relatively backward, bulky, and slightly simpler in technology. So it's very easy to repair.

If you want to repair those high-precision mechs, you can't do it without special equipment. Therefore, during the assessment, this kind of backward mecha is generally used, which can be repaired in a short time. It is impossible to say that it takes half a year to take an assessment, and then it will be over.

The power system of this mecha is broken, and the fire control system is also broken. Extensive damage, Su Xuan checked some of it, and found that it was hit by a pulse sniper, and it was hit three times before it was injured like this. However, none of this could be difficult for Su Xuan.

The first thing he repaired was the power system, which took him an hour to complete. And then there's the fire control system for all kinds of weapons. His powertrain took only half an hour to fix because it was an old-fashioned turbo. The fire control system is different, it is an arsenal, so the fire control system is very complex, there are more than a dozen machine guns of various kinds. There are also two main guns. Three laser cannons. There is also a missile launcher that can store nine ultra-long-range rockets.

After these weapon racks are repaired, they also need to be connected to various switches, each machine gun has a different switch, and it is necessary to find a matching one, and then you can link them one by one. This type of repair is not only time-consuming, but also very dangerous. If the repair is wrong, the owner of the mecha is likely to open the missile when using it, and the main gun will not be able to be fired.

Generally speaking, when the mecha is broken to this extent, it is generally for safety and will be destroyed. But only if the machinery is a union will do this, let everyone continue to repair. But Su Xuan is here for the assessment, even if he doesn't like it, he can only accept his fate.

This repair took Su Xuan an hour and a half, and after confirming it again and again, he was relieved. With the introduction of this drawing, Su Xuan is still very easy to do. At the beginning, in Professor Gu's place, he could disassemble the mecha without drawings and reassemble it later, not to mention that this was just a repair, and it was also a repair with drawings.

In the end, it took another half an hour to polish the shell damage of several houses, and it took two and a half hours before and after, and the entire mecha was repaired.

In fact, it's just a repair, just fix the general problem, but Su Xuan almost renovated him, which made everyone praise him again, and Old Man Qiu smiled and narrowed his eyes even more. But he also knew that Su Xuan was not his apprentice, but he was still very happy.

"Boy, are you interested, try how about the assessment of the fifth level."

An old man walked out with a smile and said to Su Xuan. He wasn't hostile either, just joking. He was also very optimistic about Su Xuan, and wanted to see if Su Xuan had the strength of level five. This is a watershed, if you reach level five, you can make mechas, which is very crucial.

Moreover, a fifth-level mechanic, like a seventh-level mechanic, can only make a first-level mecha, and only when it reaches the eighth level can a second-level mecha be made. In other words, if Su Xuan reached the fifth level, he would have the same strength as his mentor, but he was not as familiar with his mentor.

It is because the fifth and eighth levels are all a hurdle that this mentor of his, Old Man Qiu, has been trapped in this realm for so long without finding the slightest reason for the breakthrough.

"Thank you for your kindness, the juniors are self-aware, the fourth-level assessment is already all my strength, and the fifth-level is impossible to achieve. When I have the opportunity in the future, I will definitely come to the assessment. ”

Su Xuan would not be so arrogant and think that he could really pass the fifth-level assessment. He doesn't have this plan now, he plans to wait until he develops his own mecha, and then choose the fifth-level assessment. He didn't want to take any risks until the mech was finished, and if it failed, he would have to wait a year. Active refusal is different. After passing the test, the termination of the continued assessment is not considered a breach of contract, as long as you have confidence, you can still come to the assessment at any time.

After a few polite words to each other, the rest of the people left, after all, they also have work to do, so they can't stay here longer. And Old Man Qiu, as Su Xuan's nominal mentor, of course took Su Xuan with him.

"Little brother, thank you for speaking for me just now, I can't thank you enough."

It feels very strange to be called a little brother by an old man in his fifties and sixties. But Su Xuan also knew that the other party was in a very happy mood, and he didn't care about this, but said: "I'm not a good person myself, but I can't get used to such things, so don't be polite, I still have things, so I'll leave first." ”

Su Xuan had already spent six hours on the assessment here, so he was in a hurry to go back. But as soon as he left, he was stopped by Old Man Qiu.

"Little brother, anyway, I still want to thank you this time. To show my sincerity, I am giving you something that I got by accident. ”

The old man was talking about a palm-sized, black metal thing. It looks very ugly, and I don't know what it is.

Su Xuan originally planned not to, but Old Man Qiu's temper was also very stubborn, and in the end Su Xuan accepted it.

"Actually, I'll tell you the truth, the reason why I became a mechanic wasn't because of this stone. This stone is a family heirloom. It seems that not long after entering the cosmic age, our family has this stone. It has been passed down for countless years, and it has never been clear what this stone is.

I'm no exception, I became a mechanic in order to figure out this stone. But so far, I haven't found anything similar to this stone. I've asked a lot of people, but they don't know, and people have told me that maybe it's not metal, but a certain material, but I don't believe it, because our family has been handed down for so long, and they all say it's metal.

I've had it tested with a special agency before, and I've heard that it's a living thing, because this piece of metal is alive. If data is superstitious, I really thought this thing was made of metal. But I'm just a mechanic, not a biologist, so I don't know much either. The family has paid so much for this thing, and it's almost time for it to end. I want to give this thing to you, thank you for your help.

Don't refuse first, you think it's my heirloom, so don't plan to take it. I'm also a little selfish for you. There are quite a few talented mechanics, but I haven't met any of them, and I'm not familiar with them. But you are the most gifted young man I have ever met, reaching the realm of a mechanic at the age of seventeen. In the future, my achievements will definitely be much higher than mine. So I'm also very curious, what is this thing, I hope you have a high achievement one day, figure out what this thing is, it doesn't matter if you tell me or not, I'm just curious about this thing. ”

The other party had already said this, and Su Xuan had nothing to refuse. So he nodded in agreement.

After leaving the mechanic union, Su Xuan didn't take a taxi back immediately, because the black cat guy didn't know where he ran away, and there was no news at all. Although Su Xuan was not worried about the safety of the black cat, it was a mechanic union after all.

"Zero, can you find out what gold this metal is? Didn't you already download the technical knowledge just now, did you know it? It's okay to be idle, Su Xuan also began to study. This thing is very ordinary no matter how you look at it, but it is regarded as a family heirloom. So curiosity can't help but be seduced/lured.

"Report to the owner, according to the probe, there is no metal that meets the requirements at all. And the old man has studied it for so many years, if there really is, he will definitely know about it. According to the analysis, there are nine layers of certainty that this thing is a non-metallic material, and many metals have no properties, and it cannot be found out for the time being. But ......"

When he said this, Zhi Brain rarely hesitated.
