Before the year 2000 of the Federation Calendar, mechas were always in a purely mechanical structure mode.

It was not until 2005 that a genius came up with a bold idea, which was the original model of what was later called the neuron module - parts modularization.

The so-called modular parts means dividing an entire mecha into multiple parts such as hands, arms, legs, feet, head, torso, etc., and then stacking them in a stacking block pattern.

In the year 2005 of the Federation calendar, during the war, this model was vigorously promoted by the Interstellar Federation because it facilitated the assembly and maintenance of mechas. Even after the next few hundred years, a new model of neural modules was developed.

Lin Tao, who had read the history around 2000 in detail, could recognize at a glance that the woman standing on the podium, although she looked young, was none other than the genius who proposed the idea of ​​modular parts - Liu Xueying.

I never expected that I would see a person who would be regarded as a big shot in later generations just after entering Hyacinth College.

Lin Tao was shocked.

Wait!

Suddenly, Lin Tao's pupils contracted.

In his memory, this Liu Xueying seemed to be from the First Academy of the Interstellar Federation, not the current Hyacinth Academy, and even the name of Hyacinth Academy was not mentioned.

What is going on?

Is there any hidden secret in the historical materials? Just when Lin Tao was shocked, Liu Xueying had already started the lecture.

"Is it her?" Lin Tao was surprised again when he heard her voice.

Previously, Lin Tao was shocked by the woman's identity and did not pay attention to her voice. But when he listened carefully, he recognized her. This Liu Xueying was the one who used the watch to urge him to return to the college.

Thinking back to what this girl said before, it seems that she still cares about her students.

Lin Tao nodded secretly.

However, after hearing Liu Xueying's lecture content and her strange tone of voice, Lin Tao was stunned again.

His voice was cold and his tone was slow. He read out the information in the book word for word like a robot. This was his evaluation of Liu Xueying.

Is this kind of lecturer really a kind-hearted person?

Isn't he afraid that his students will run away and he will be punished? Lin Tao frowned. If he really is such a person, even if he is a great man in the future, Lin Tao will never let him off easily, because he despises such a mentor.

While thinking this, Lin Tao glanced around, and this time, it was his turn to look strange.

Seeing the lustful students around him, Lin Tao finally understood why Liu Xueying adopted such a boring teaching method.

Those guys were probably people who had never seen a woman before. Seeing their lustful eyes, Lin Tao also felt disgusted.

In this situation, Lin Tao only listened for a while, immediately lost interest, and started looking through the information on the computer on the desk again.

There are actually quite a few students like Lin Tao who study on their own in class.

And these students are the ones who are truly focused on their studies in this class, because what Liu Xueying talks about is basically recorded in the books. As long as they are more eager to learn, they may be able to learn a lot in advance.

Lin Tao looked through the information. The maintenance technology of pure mechanical mecha was also passed down to later generations. However, due to the differences in the times, there was still some generation gap. Many theories had been eliminated by new theories in later generations.

Woo~ Woo~ When Lin Tao was concentrating on looking up some information, he suddenly heard a series of urgent sounds in his ears, and at the same time, the computer screen on the desk flashed red.

Looked up suddenly.

Everyone in the class, including the instructor Liu Xueying on the podium, looked at him.

What's going on? Lin Tao felt strange.

"Lin Tao, please explain the difficulty of repairing the mecha joints."

Liu Xueying, who was sitting on the podium, had a stern face, her beautiful icy eyes fixed on him, and asked in a cold tone.

Lin Tao immediately understood that this question was asked to him in class.

"This... um, this..." Lin Tao stood up suddenly.

"What's going on with this guy?"

"Why don't you just sit there and answer the question? Why do you stand up? Do you want to be the first to stand out?"

Everyone in the class burst into laughter, especially Chi Zhengfei and He Fan, who had mocking expressions on their faces and laughed the loudest.

It turns out there is no need to stand up. Lin Tao shrugged and sat back down.

Liu Xueying's eyebrows were raised and her eyes were filled with extreme disappointment.

Seeing her look, Lin Tao's heart moved, and he remembered that in his later life, he had dismantled several purely mechanical mechas in his collection many times.

The purely mechanical mechas of later generations are generally only collected by ancient martial arts mecha warriors, because operating these machines may allow them to unlock... no, realize some new movements.

Although Lin Tao is not an expert in repairing mecha joints made around 2000, after many operations, he has a few complaints about the performance of these joints.

Immediately, Lin Tao came up with a plan to deal with it and stood up again.

"Regarding the joints of the mecha, we all know that the joints of the mecha are very important steering systems, which allow the mecha to turn in multiple directions and thus perform different actions." Lin Tao spoke loudly.

Lin Tao's words had already been recorded in the book, but when Lin Tao sat up and stood up suddenly, Liu Xueying on the podium looked at him strangely, and even those students who were concentrating on the class looked over at him again.

Chi Zhengfei and He Fan curled their lips on the spot and glanced at Lin Tao coldly. They knew Lin Tao's strength very well. He looked like a king, but in fact he was not even as good as a bronze player. He stood up again and again, definitely to attract the attention of the beautiful mentor. Suddenly, the two looked at Lin Tao with a hint of contempt.

"About pure mechanics..."

Lin Tao almost let it slip that there was no such thing as a purely mechanical structure in this era. He quickly corrected himself: "As for the current mecha, in order to be able to accurately control parts such as the finger joints, there are a large number of circuits inside. The existence of these circuits greatly reduces the mobility of the joints, and even the reaction ability has decreased..."

Next, Lin Tao started to fiercely complain about the purely mechanical mecha.

It has to be said that compared with the mechas of later generations, after disassembling the mechanical structure mechas in his collection many times, Lin Tao immediately realized that due to the existence of a large number of lines and the use of them without any chapters, even the joints had to make room for the lines to pass, which made the body's reaction ability relatively rigid. In order to make quick and accurate movements, a certain amount of advance time is required.

To sum it up in one sentence, these pre-installed accessories make the mecha more bloated, and the maneuverability of the body becomes more rigid.

This is equivalent to forming a vicious cycle.

"This design makes it much more difficult to repair the machine. Once the line is disconnected, the entire machine must be disassembled and the broken line must be slowly pulled out and replaced."

"If we can come up with some new joint modes, it will not only make the mecha lighter, but also greatly reduce the difficulty of maintenance."

…

Soon, Lin Tao brought up a lot of complaints.

"Um?"

Suddenly, Lin Tao noticed that the whole classroom fell into an abrupt silence.

He stopped and saw his instructor Liu Xueying tilting her head and looking at him with a half-smile. Even the students around him were shocked and looked unbelievable.

Oops!

Lin Tao suddenly realized that this was the Mecha Maintenance Department. If his complaints about the mecha joints appeared in the Mecha Design Department, it might shock everyone. However, the students here would not care about these. They would only think about how to repair the mecha.

Just then, two mocking voices were heard from one side of the classroom.

"Hahahaha... Lin Tao, we are only in the maintenance department. You can only go to the design department for these things you mentioned." A sarcastic voice sounded from one side of the classroom. The person who spoke was Chi Zhengfei, who looked like a social ruffian.

"That's right, that's right." Another golden-haired He Fan also said sarcastically: "Lin Tao, I didn't expect that you can fly when running a train. If you are really capable, how come you can't even modify a hover car?"

Originally, many students had covered their mouths and laughed secretly after hearing what Chi Zhengfei said. Now, after hearing that Lin Tao couldn't even modify the hovercraft, they burst into laughter on the spot.

A person who couldn't even modify a hovercraft dared to exaggerate in class and bring up things from the design department. Did he really think that no one in their class 97 was paying attention to the class? You know, those maintenance students who paid attention to the class could modify not only the hovercraft, but also the mecha.

Lin Tao frowned slightly and tried hard to search his mind for memories related to these two people.

Here we come!

Immediately, memories of these two people immediately emerged in my mind.

These two men, one is named Chi Zhengfei and the other is named He Fan. Four days ago, which was the day before Lin Tao arrived in this time and space, the two of them agreed that the original owner of this body would go and help a man named Liu Zhengwei to modify the hovercraft.

However, Lin Tao's hidden illness broke out at that time, and his hands and feet were shaking. He accidentally modified the engine and blew it up, so the three of them were beaten out on the spot by Liu Zhengwei's thugs.

Chi Zhengfei and He Fan seemed to have intended to use this opportunity to please Liu Zhengwei, but Lin Tao's move ruined their chances. The two of them fought with the original owner of the body on the spot, which aggravated their illness and led to their death in the rental house in the middle of the night.

"It turns out to be these two guys." Lin Tao's face darkened. After all, he is now the owner of this body.

"Enough, be quiet!"

Seeing that the classroom was in chaos, Liu Xueying couldn't help but shout loudly.

Although Liu Xueying was young, she was still a mentor. With her angry shout, even Chi Zhengfei and He Fan had to shut up.

After she stared coldly at Chi Zhengfei and He Fan, she saw that many students in the classroom who were concentrating on their studies were also motivated by these two people, and the smile on their faces gradually disappeared.

"Although the knowledge that Lin Tao mentioned is related to the design department, the role of our maintenance department is not just to repair mechas." Liu Xueying said in a cold voice with a straight face.

"Do you know that if we don't have feedback from the maintenance department on the mecha's shortcomings, how can the design department design the next mecha based on these contents to avoid these shortcomings?"

Having said that, Liu Xueying glanced coldly at Chi Zhengfei and the other man.

The cold eyes made the two men shiver for no reason and lower their heads at the same time. They would not bear a grudge against Liu Xueying, but they hated Lin Tao very much. If Lin Tao had not spoken, they would not have been scolded by the beautiful tutor.

"Teacher Xueying, if we have this much money, we might as well just enroll in the Design Department instead of coming to the Maintenance Department."

"Yeah, we are just poor students, how can we possibly study design?"

In class, several students raised objections on the spot, saying that the tuition fee of the Maintenance Department was much cheaper than that of the Design Department.

Liu Xueying opened her mouth, looked at them, sighed in her heart, and didn't know what to say for a moment.

"Don't you think you will never achieve anything in your life?"

Suddenly, an old man with a goatee and a thin face walked into the classroom door.

"Dean."

"Dean of the Gu Lei Department."

All the students turned their heads and screamed.
