Li Xiang stood in the room, feeling the steam that broke into the body, which was mixed with gas essentia, and when it poured into the body, there would be a feeling like an electric shock, and the cells in his body seemed to be mobilized, as if he saw several lines of different colors spreading, stretching, and flickering in the body.

As Rocca said, the higher the level of talent, the easier it is to perceive the magic circuit.

The coolness surging on his limbs was the strongest, and the accompanying pain was also more intense, and the red lines were clear, which was his only S-class magic circuit.

After that, there is the yellow visceral magic circuit, A-grade, the pale yellow lines all over his internal organs are not so clear compared to those on his limbs, and the blue lines engraved on the bones are a little lighter, and finally the orange lines on the facial features are the lightest in color, and they can't be distinguished without looking carefully.

Li Xiang was enduring the changes in his body while reading the seconds softly, now that five minutes had passed, according to the time of the second-class trainees, the time he could stay in the essentia decomposition room would not exceed ten minutes at most.

After already perceiving all four magic circuits that he had awakened, Li Xiang quickly tried to communicate with the red lines on his limbs, and now he had the effect of essentia, and he could clearly feel the magic circuits on his limbs, including the magic particles swimming on them.

As for how to get a magic circuit into the "knowing" state, Rocca didn't say anything, nor did he mention anything about cultivating magic circuits.

It seems that this kind of cultivation can only be understood but not spoken.

He could only use all the methods he could think of, trying to awaken the magic circuit that seemed to be still sleeping. Since the limb talent level is the highest, in order to be able to reach the state of "knowing" a magic circuit within ten days as soon as possible, he just concentrates on conquering this one.

Time flies little by little, Li Xiang's attempts all ended in failure, and he always feels that he is still a little short, and every time it seems that when he is about to succeed, his perception declines rapidly, and then he has to start again.

He didn't know that the absorption on the first day was actually just to allow them to perceive the magic circuit in the body, and the effect of the human body's first absorption of essentia was very poor, and only after a few days of adaptation could they slowly use it, and it was already very powerful to reach this step.

Li Xiang took a deep breath and kept thinking about the reason for his failure, and while thinking, his hand subconsciously leaned on the huge metal pipe in front of him.

Obsolete essentia decomposer, durability: 69%.

The sudden appearance of small lines of steam text startled him, and the gray-white scale bar below also jumped.

Essentia: 1%.

Just touching this essentia decomposer can increase the liquefied essentia by 0.4%?

It seems that the increase in the amount of essentia is related to the advanced degree of the machinery.

"I inadvertently used the liquefied essentia in it on Sister Shanshan's steam gun, which not only allowed her to use machinery that could only be used, but also enhanced the power of the air column. So can I just try using essentia to increase the durability of this essentia?"

But doesn't durability mean how long it can be used normally? It should be a value like efficiency, right?

Seeing that the time was about to come, he had no choice but to try to drive this essentia decomposition machine first.

Li Xiang recalled the feeling he had when he held the steam gun, and after a few seconds, a white spinning gear appeared in his pupils again, and then the liquefied essentia in the gray-white scale bar suddenly decreased.

essentia: 0.9%.

At that moment, the essentia decomposition machine outside suddenly began to operate at high speed, and the huge noise of mechanical parts attracted both Roca and Han Shi not far away.

"This thing is not going to fall into disrepair and be scrapped, is it? Han Shi looked at the essentia decomposition machine that made a strange noise, and asked puzzledly, "You are an expert in this area, take a look!"

Roca shook his head: "There are still trainees in it now, rashly touching the essentia decomposition machine may cause immeasurable damage to him, listening to the sound is just that the lubricating oil between the parts is not enough, wait for him to come out in a while, I will open it and take a look." ”

The movement of the essentia decomposition machine did not last long, and soon returned to normal, and the ten minutes of perception time passed, and a piercing bell rang, and the steam in each essentia decomposition room stopped spewing.

The iron doors opened one by one, and the trainees who were about to collapse walked out with difficulty, but they were all red and excited.

Han Shi yelled for them to line up quickly, Li Xiang was a little light when he came out of the essentia decomposition room, and after the essentia decomposition machine suddenly increased its power, he was almost overwhelmed by a large amount of steam.

The effect was also obvious, at the last moment, the red lines on his limbs were almost half lit up, so that tomorrow this magic circuit would be able to reach the state of knowing.

After Li thought they left, Roca walked to the essentia decomposition machine and fiddled with it for a while, making a puzzled voice: "Strange, there is nothing wrong with the machine, is it really that the lubricating oil is not enough?"

On the other side, the aura of mad iron at the head of the queue was strong, and it didn't seem to be affected much, and Chen Fan behind him was lying on his shoulder like a dead dog, looking like he had suffered a lot.

Seeing that the trainees in the first class also looked so weak after they came out, the trainees behind were nervous but expectant.

There was still about half an hour left for daily training that was canceled by Han Shi, and he deeply felt the pain of receiving essentia on the first day, so he let them go to the cafeteria to eat with a wave of his hand.

After dinner, most of the people collapsed on the bed, and Chen Fan, who had always been lively, did not speak, and fell asleep with a pillow in his arms.

The pain of absorbing essentia for the first time was just beginning, and the body seemed to have turned on a switch, becoming extremely weak, and the slightest touch could bring a sharp pain.

Lying motionless on the bed, once the drowsiness surged, the pain also followed, and Li Xiang absorbed most of the essentia in this way, and the pain was still several times higher than theirs.

After being paralyzed for half an hour, they had to get up and run to the school building for a cultural class.

The evening culture class was not a magic circuit class, and the teacher was still Roca, but the mercenaries behind him came to the classroom one by one carrying black boxes, and then everyone put down such a black box next to them, and there was also one on the podium.

"Congratulations to all of you on your first absorption of essentia today, and hopefully in the next ten days, all of you will succeed in reaching the state of knowing. Tonight I'm going to teach a new course, and it's my old job at the Recursive Steam University of Technology, Steam Technology. Roca clapped his hands and said with a light smile.

"As we all know, steam technology is the most important civilization technology we have at present, and it is indispensable in life and in battle. Transportation, weapons and equipment, daily necessities, everywhere. Our steam mechanical devices generally use a mixture of steam and mechanical parts, and some special ones, such as the essentia decomposer you saw this afternoon, also have essentia driving force in it. ”

Rocca turned over the black box on the podium with one hand, then opened it, and with a click, revealing the contents one by one.

It is a small, intricately constructed metal worktop with a bright steam lamp rising from the corner of the countertop, illuminating the entire countertop.

The metal worktop was covered with various fine lines, and many small tools that Li Xiang had never seen before penetrated it.

"To learn this technique, you need two points, the first is to be proficient in theoretical knowledge, and the textbook attached to it is an introduction to steam technology, and you can memorize it within three days when you go back. The second is to be proficient in practical techniques, including drawings, production and maintenance, etc., this console is the latest style of mechanical structure test bench, after entering the steam technology major of the excellent university, everyone will be equipped with one, worth 1 million blue star coins. ”

Li Xiang was dumbfounded, and many trainees in the audience also let out a voice of emotion, and only a few people with good family backgrounds behaved extremely indifferently.

The importance of steam technology is self-evident, even if you become a player in the future, it is difficult to separate from these mechanical devices, and a good set of steam mechanical equipment is definitely one of the highest pursuits of every player.

"Because of the special nature of the polar night, our course will not cover too deep content, and the only things that need to be mastered this month are three contents: analysis and identification drawings, understanding and use of the structure of steam mechanical weapons, and preliminary maintenance. I hope that through this course, you will have a basic concept of weapons, as well as the ability to use and maintain them, which is an important skill that can save your life on the battlefield. ”

After saying this, Roca quickly began the class, starting with the most basic theory, and at the same time interspersed with the explanation of the mechanical construction table, including the use and function of the various tools on it.

This is also Li Xiang's old business, and at the same time, it is what he is most interested in, so he listens very carefully, has the background of the past, and understands it quickly, and his talent in learning steam technology technology is immediately noticed by Roca.

Rocca himself is from this professional background, and after smelling a temperament similar to his own from Li Xiang, he is also deeply grateful, and often takes the time to answer his doubts, in the eyes of other trainees, Li Xiang's talent in mechanical and steam technology is not in the same dimension as theirs.

"Guys, this is a essentia-driven gun loaded with active gas, ordinary steam guns are common everywhere, and this kind of gun, they are the real battlefield killers. Rocca took out a well-made pistol from the black box, engraved with intricate patterns, and the whole thing looked magnificent, more like a work of art.

Li Xiang noticed that the inner wall of the gun body was engraved with the mark of the Dong Ling family.

"This is the essentia gun produced by Dongling Heavy Industry, and the difference between Bai's Heavy Industry is that the product shape of Dongling Heavy Industry is more gorgeous and cool, and the essentia standard tube will be placed inside the gun body, while Bai's Heavy Industry is simple and simple, and the standard tube is placed on the outside. ”
