"Of course, you won't have access to this special essentia gun until you become an apprentice magician. The essentia gun is expensive to build, and the standard tube gas essentia used alone is not something that ordinary people can afford, and firing a gun also requires a lot of energy, so in the future you will slowly understand that sometimes relying on a large force is more important than a strong talent. ”

Rocca toyed with the essentia gun in his hand and put it back down.

"From this class onwards, we will first take a lesson on drawings, and now we will take out a prepared drawing from the black box. Rocca said as he took out a small stack of drawings from his black box, the paper was special, and it seemed to use a more durable and textured parchment.

There are a total of six drawings, Li Xiang flipped through them, and found that the drawing technology in this world is much more advanced than in the previous life, and the equipment is perfect, which is clear at a glance.

"You should understand that the drawing is the soul of a mechanical device, we can get all the properties and production methods of it from the drawing, to make a mechanical device, as long as there are enough high-end production tools and sufficient raw materials, coupled with the skilled and exquisite technology of the maker, it will be successful, but the only irreplaceable is the original drawing of the device. Therefore, if you are only good at practice and production, at most you are only a senior technician, not a designer, and only those who can draw design drawings by themselves can be regarded as a real machinist. ”

Speaking of this, Roca sighed softly, these teenagers and girls below don't seem to understand, and they don't blame them, after all, this is too far away from them, but for a person like him who has already entered the threshold, after seeing only a corner of the mechanical palace, he understands that the mysteries and endless knowledge inside are enough to entangle them for a lifetime.

Countless people have spent their lives researching to become real mechanics, and a top mechanic is even worth more than some players.

Naturally, Rocca didn't reveal this to them here, he just introduced the importance of drawings, and began to formally teach the trainees how to identify drawings, including their meanings and authenticity.

"Theoretically, drawings are the core technology, and now you have in front of you a drawing of the simplest basic steam pistol, isn't it cumbersome, this is just the beginning. Rocca smiled and analyzed the drawings, and while he was lecturing, the trainees not only listened carefully but also took the time to go through the textbook to get started.

They don't have a lot of time to study and digest slowly, and in the polar night, learning is a race against time.

If you don't read the book in the time just now, you won't be able to understand a lot of the content taught by Rocca now, and if you don't understand it, it means that the lesson is in vain, and then you have to spend time to make up for it, and the sequence ranking after the class will drop, and the resources you get will be reduced, so it snowballs, and it may inadvertently become the bottom of the class.

Li Xiang has the special ability of mechanical mastery, and he is also extremely sensitive to this kind of thing, and his talent is extremely strong, he fiddles with the metal console, and has the ability to "see" like a fish in water.

In this class, he was the only trainee who could keep up with Roca, and his amazing mechanical talent was undoubtedly revealed, and even Rocca was shocked.

After touching the blueprint of the basic steam pistol, the drawing symbol that had been in a gray state suddenly lit up, and Li Xiang tried to open it, and sure enough, the drawing was stored inside.

There are countless small gray squares in the blueprint symbols, which look like the equipment slot in the game, and the basic steam pistol blueprint is in the first grid, and there is actually a plus-like thing on it, Li Xiang tried to click on it, and found that the original 0.9% liquefied essentia was instantly reduced by 0.4%, jumping to 0.5%.

And the drawing also emitted a glimmer of light, and then countless information frantically poured into Li Xiang's mind.

"Is this the content of the drawings that have been deconstructed?" Li Xiang can check the contents of the drawings very freely, as if he has studied them countless times, and now he has all the contents of the drawings clearly, without a trace of doubt.

Consuming liquefied essentia allows you to directly understand the content of the drawing, but it is too luxurious to consume 0.4% of the liquefied essentia for just the most basic drawing.

He only used 0.1% of it in the essena decomposition chamber.

The evening cultural classes are very intense, and Roca imparts a lot of knowledge to them non-stop, regardless of whether they can digest it or not, this is the polar night, and everywhere they are required to be able to break through the limits to learn.

Most of the trainees frowned, this thing was too difficult for them who had never touched a mechanical device, and they had to master these contents in a class, except for Li Xiang, no one else could do it.

"Okay, that's all for today's lesson, there's still about half an hour left, I'm going to arrange a small test for you, it will be related to your sequence ranking after class, so please cheer up and work hard. Rocca clapped his hands and let out a long sigh, he was not so nervous about teaching his coursework at the university, and Polar Night's requirements were too high.

Hearing that there was a test, the trainees all looked up, held their breath, and waited for his request.

"Do you see the basic steam pistol drawings you have in your hand? I'm almost done explaining just now, you check the textbook, and then use the metal console to try to assemble and make one, don't be nervous, even if you fail, it's fine. Roca clicked on the black box, which contained all the raw materials and the latest metal console, so it was not a problem to assemble and make the simplest steam pistol.

This is actually the content of the monthly exam that will only be available a month after entering the university, and now it is difficult to ask them to do it when it comes to a class.

The trainees did not complain, but directly took out the raw materials and placed them neatly and began the manual operation.

With the advantage of drawing deconstruction, Li Xiang quickly got started, and he put on a monocular magnifying glass, which is used to observe when operating internal parts, and the assembly of firearms in this world is very different from the previous life.

There are some precision parts that need to be polished by hand, and the splicing project must be completed by hand, and there is an extremely complex mechanical structure inside the steam gun, which can not be completed by assembling a few spare parts.

At present, only the two major heavy industries and Wessex Technology Company have large-scale devices for mass production of machinery, and generally small forces buy all kinds of devices from them, or look for some personal mechanics to customize them on the black market.

Li Xiang's movements are smooth, Rao is so, and he has failed several times in the initial work, even if he deconstructs the drawings, he still has the ability to be proficient in mechanics, but he still needs a lot of repetitive practice to get familiar with it, not to mention those trainees who have never been exposed to this and do not have these abilities.

In fact, in a specialized university like the Recursive Steam University of Technology, only the top mechanical geniuses can complete their first mechanical production in a week.

Roca patrolled around, the mercenaries of those guards had different expressions, the requirements of the polar night were too harsh, not to mention these trainees, even most of them who were experienced in a hundred battles had not yet mastered this skill.

I actually asked them to start trying their hand at mechanical production in one class......

What kind of monsters are going to be cultivated here?

Soon, Roca's footsteps stopped beside Li Xiang, at first he didn't expect these trainees to make anything decent, this small test was mainly to test their speed of absorbing knowledge and make them understand the difficulty of the course.

But the young man in front of him was calm and calm, not arrogant or impatient, and was actually heading towards the finished product in an orderly manner.

Judging from his still somewhat unfamiliar skills, Li Xiang is definitely the first time to touch these things, but as soon as the tools come into his hands, they seem to be alive, and some of the other trainees don't know how to use some precision tools, but he is already proficient, but he is still a little immature in the production process.

After all, Roca hasn't taught them the real crafting techniques yet.

"Alright, it's time!" Roca clapped his hands, and all the trainees immediately stopped moving, obeying the instructor's orders was the top three iron rules of discipline, and after the course was over, the mercenaries came over and sorted out all the black boxes beside them.

Li Xiang looked at the finished product that was only less than one-third completed, and a wry smile appeared on his face, he still thought too simply, he was not the protagonist in a time-traveling novel, even if he had a little special ability, he would not instantly block and kill God, and Buddha would block and kill Buddha.

The ability to master the machine only made his talent to the next level, and he had to put in enough effort to really grow.

The slight setbacks did not make Li Xiang too lost, but made him more interested, and challenging things are fun.

Then Roca announced the sequence ranking, the first place was still Crazy Iron, Li Xiang was still in second place, and the third was a red-haired boy named Amakusa Lie, and Chen Fan fell to fourth place.

Li Xiang had paid attention to this Amakusa Lie before, and his name was different, he was a very taciturn person, always alone, giving people a very low-key feeling, not outstanding in daily training and cultural classes, but firmly occupying the top position in the class.

He had been hovering from sixth to eighth before, but now he sprinted to third place, and the first Crazy Iron's performance in this class is generally still firmly in the first place, which shows that he has a certain gap with Li Xiang in daily training.

"Is this guy a humanoid beast? Li Xiang muttered in his heart for a while, and became more concerned about this crazy iron.

There is a mid-term test in a month, and a final test in two months, and only after passing the final final test can you be considered an official graduate, and if you don't even pass the mid-term, then the outcome can be imagined.

The last batch of 300 people finally only went out of 16 people, according to this elimination method is obviously impossible to happen, and there will inevitably be a more cruel elimination mechanism in the future of Polar Night.

Calculating several possibilities, he didn't dare to slack off at all, the trainees were competitors with each other, maybe they would face each other with swords, Li Xiang would spend some time collecting information about other people, in case of emergency.
