Mecha Manufacturing Department classroom.

"Today we are going to talk about the internal wiring layout of the mecha. The operation of each mecha is first operated by a mecha operator in the cockpit, and then the instructions are transmitted to every part of the mecha through these lines. Therefore, the wiring layout of the mecha is knowledge that every mecha manufacturer must master." Professor Qin said, while projecting a diagram of the internal structure of the mecha on the blackboard.

"Finally, it's time for the class you're most interested in." He Shao whispered to Yan Hao.

"Yeah." Yan Hao's eyes sparkled, and he looked extremely excited. He had been looking forward to this class for a long time. After three months of intensive study, he had basically mastered the basic knowledge of mecha manufacturing, but there were still many problems with this mecha circuit diagram.

"Is there any student who knows about the research direction of current science and technology on mecha circuits?" Professor Qin suddenly asked.

"Teacher, I know." Someone raised his hand.

"Okay, tell me about it."

"The current research direction is to simplify the internal circuit diagram of the mecha as much as possible to achieve the purpose of simplifying operation."

"Yes, it seems that our students are still keeping up with current affairs." Professor Qin laughed and began to explain, "Every circuit in the mecha is used to convey instructions. For example, the circuit in the arm is used to operate the fingers, this one is used to bend the arm, and this one is used to control the direction. Under these basic circuits, there are many small circuits, which are used to complete more sophisticated operations. And these operations require the driver to input commands in sequence in the cockpit. Once a command is operated incorrectly, the action of the mecha cannot be completed."

"Therefore, the operation of mechas is very difficult, requiring the driver to have strong physical and mental strength. If the mental strength is not enough, it will be impossible to remember the huge operating instructions, and if the physique is not strong, it will be impossible to complete the operation in a short time. Because of this, the Federation's mecha warriors were in short supply for a long time."

Yan Hao nodded repeatedly. Every young man has a mecha dream, but the more he knows about mechas, the more Yan Hao knows that he can't become a mecha pilot because his physique is not enough to support him to complete high-intensity command operations.

"And in order to solve this problem, the Federation of Mechas had the earliest classification of mechas. Mechas are divided into levels one to ten." Professor Qin said, switching the commissioning image and replacing it with a projection with a total of six mecha circuit diagrams.

"Here is the circuit diagram of level one to six mechas. What did you find?" Professor Qin asked.

"The lines are becoming more and more complicated," the students soon discovered.

"Yes, the circuits are getting more and more complicated." Professor Qin introduced, "Level 1 to 3 mechas only have simple operating instructions and cannot be equipped with weapons. Normally, any citizen of our Federation, as long as they are not disabled, can operate them."

"Hahaha..." Laughter suddenly broke out in the classroom.

"There is a fundamental change from level 3 mecha to level 4 mecha. Can you see it from the picture?" Professor Qin continued to ask.

"Teacher, I know this. After the fourth-level mecha, the joints of the mecha will be much more flexible." Someone raised his hand to answer.

"Okay, that's right." Professor Qin enlarged the image on the projection, fixed it on the circuit diagrams of the third-level mecha and the fourth-level mecha, and asked, "Then can you calculate from these two diagrams why the fourth-level mecha is so flexible?"

The students who had just been speaking enthusiastically suddenly became quiet.

Mechas have existed for a long time, so although not everyone in the Federation can drive a mecha, some differences between mechas are still known. For example, the joints of a level 4 mecha are more flexible than those of a level 3 mecha, which is something everyone knows. But what Professor Qin asked was to find out the reason for the flexibility from these two pictures, which is difficult.

Professor Qin saw that everyone was quiet, smiled and said, "Students, don't be nervous, speak boldly. You have just started learning, and it is normal to make mistakes, but you must dare to think."

“……”The classroom was still quiet.

"It seems that I can only call the roll." Professor Qin glanced around the classroom and then looked at the last row.

"Oh my god, why are you looking at us? Please don't call me." He Shao lowered his head and prayed desperately.

Professor Qin's gaze did fall in the direction of He Shao, but he was not looking at He Shao, but at Yan Hao, who was sitting next to him and looking at the blackboard with bright eyes.

Professor Qin was still very impressed with Yan Hao. After all, it was rare to find someone who could deliberately control the efficiency of an energy block to 76%, not more or less. He found something strange at the time, so he deliberately gave him a difficult question, asking him to bring another level 5 energy block in half a month. Unexpectedly, this kid actually brought one. Although the level 5 energy block he brought was only 69.88% efficient, it did not reach the excellent level. But you have to know that he had not yet taught the production formula of the level 5 energy block in class, and learning to make a level 5 energy block was the school's requirement for students at the end of the semester. When Yan Hao made it, it had only been a month since the start of school.

It can be seen from this that Yan Hao has mental and computing abilities that surpass his peers. These two points are very important for mecha manufacturing, especially computing ability.

"Yan Hao." Professor Qin shouted.

When he shouted, most of the students in the classroom breathed a sigh of relief and looked in the direction of Yan Hao.

Yan Hao was stunned for a moment, then stood up: "Teacher."

"You answer the question I just asked." Professor Qin said.

"I think the reason why the fourth-level mecha is more flexible than the third-level mecha is because the circuits in his body are more complicated."

As soon as Yan Hao said this, boos were heard in the classroom. Isn't this nonsense? The professor said at the beginning that the more circuits a mecha has, the more flexible it is.

"Everyone, please be quiet and listen to what Yan Hao has to say." Professor Qin saw that Yan Hao had not finished speaking.

Yan Hao calmed down and continued, "I have calculated that the fourth-level mecha has 126 more wires than the third-level mecha, of which 10 are in the torso, 78 are in the hands, and the remaining 38 are in the legs. This makes the fourth-level mecha 300.15% more sensitive than the third-level mecha in terms of arms and 120.25% more sensitive in terms of legs, and consumes more than three times the energy. At the same time, it realizes the controllability of the fingers, allowing the mecha to complete some simple and delicate operations. But at the same time, the fourth-level mecha has at least more than a hundred more operating instructions than the third-level mecha, considering the feasibility. Also, on his arms, counting from the outside to the inside, the eighth to twentieth wires are..."

Everyone was stunned as Yan Hao revealed the specific numbers one by one. This, this was too precise.

"Okay, that's enough. Sit down." Professor Qin raised his hand to signal Yan Hao to sit down. "It seems that Yan Hao has done a good job in preparation. He can already distinguish the function of each circuit in the mecha. That's right, the goal of this course is to understand the function of each circuit in the mecha. Only by understanding their functions can we arrange reasonable circuits according to needs when making the mecha."

"Teacher, how many levels of mecha circuit diagram do I need to master?" a student asked.

"Of course I have mastered them all." said Professor Qin.

"What?! But there are more than 6,000 circuits inside a level 6 mecha." The students wailed.

"You're already screaming at the sight of more than 6,000 lines, so what about the seventh, eighth, or even tenth-level mechas?" Professor Qin said calmly, "I might as well tell you that if you can't remember these lines in your first semester of freshman year, you'll just have to wait to be held back."

"Ah?!" There was another scream in the classroom, and He Shao's scream was the loudest.

Yan Hao looked at He Shao and comforted him: "What the teacher said is scary, but in fact, there are rules for what you can't remember."

He Shao looked at Yan Hao in disbelief and asked, "You...you haven't remembered it yet, have you?"

"No, I only remember up to level 4." Yan Hao shook his head.

He Shao rolled his eyes and fell on the desk.

"Get up and listen to the class. The teacher is talking about the arrangement of the lines. If you understand it, you will be able to master the rules." Yan Hao pulled up He Shao, who had lost all hope in life.

At the end of the class, the vast amount of knowledge made these freshmen feel like their brains were deprived of oxygen. Professor Qin looked at the "destroyed" and hopeless flowers of the motherland and still smiled: "There is still a month before the final exam. The knowledge points of this lesson account for at least 30 points. Go back and review them well."

"Ah?!!!" There was another scream in the classroom.

Professor Qin has been teaching for many years, and what he loves to hear most is the cute screams of students, which makes him feel extremely accomplished. After packing up his things, Professor Qin waved and walked out of the classroom.

"How desperate was I to apply for the Mecha Manufacturing Department? Am I crazy?" He Shao grabbed his hair frantically. After venting his anger, he was about to drag Yan Hao to eat, but he saw Yan Hao staring at the direction of the professor's door with a strange expression, as if he was gathering up great courage.

"Hao, what's wrong with you?" He Shao asked curiously. It was fine if he was bullied by the teacher, but Yan Hao was a genius student and should not be bullied.

"He Shao, please come with me." Yan Hao seemed to have finally made up his mind and said to He Shao.

"What for?"

"I have another question for you, teacher." Yan Hao said.

"..." He Shao rolled his eyes fiercely, "You were sitting there for a long time just wondering whether you should ask the teacher a question?"

"Yeah." Yan Hao nodded.

"Why hesitate about this? Just go ahead. I thought you were going to confess to someone."

"You, please go with me." Yan Hao begged.

For others, it is a very normal thing to ask a teacher for help, but for Yan Hao, the experience is not so good. Yan Hao has a strong learning ability since he was a child. Because he has few friends, he basically reads books in his spare time, and he is most interested in mathematics. When he was in elementary school, he could get the answers to most of the knowledge points through books. When he was in middle school, many knowledge points were no longer in the books, so he went to find a teacher.

As a vicious male supporting role, in contrast to the protagonist Yan Fei, people around him don't have a very good impression of him. So when Yan Hao asked a very profound question that the teacher couldn't answer, the teacher got angry: "What do you mean, are you deliberately looking for trouble? You asked me this theorem that has not been verified yet, to show that you are better at math than me, right? It seems that it's not enough for you to use your grades to hit your brother, now you want to humiliate even the teacher?"

From then on, Yan Hao never asked the teacher any questions again. Firstly, he found that the teacher might not know the answers to the questions he asked, and secondly, he never wanted to be scolded again.

But after his rebirth, he had a new life, new classmates, new friends, especially the last time Yan Fei came to see him, it was the first time he was not disliked because of Yan Fei. This gave him confidence again, maybe this time the teacher would not treat him the same way as before.

He Shao naturally didn't know that Yan Hao had such an experience. He thought Yan Hao was shy and didn't dare to go to the teacher alone, so he agreed: "Okay, but you have to teach me the circuit map later."

"Yeah." Yan Hao nodded heavily, pulled He Shao and rushed out.

Professor Qin didn't walk very fast and was soon caught up by the two men.

"Professor Qin, we have some questions for you." He Shao shouted from a distance.

Professor Qin turned around when he heard the voice, and when he saw that the people chasing him were Yan Hao and He Shao, the expression on his face immediately became meaningful.

It’s this little guy. Three months after school started, he finally knows how to ask the teacher for help.

"What's the problem?" Professor Qin and the other two ran closer and asked.

"Teacher, yes, I have some questions to ask." Yan Hao said nervously.

"I know it's you, tell me."

"It's like this, teacher. I recently found a problem when I was studying the circuit diagram of a mecha." When it comes to professional knowledge, Yan Hao's nervousness disappears and he begins to talk endlessly. "The more complex the circuit, the more sensitive the mecha, but the more complex the mecha, the more difficult it is to operate. This leads to the fact that the more advanced the mecha, the less people can control it. In this case, there is no point in our research on mechas. But intelligent robots are obviously very mature, and many robots can imitate human movements through external sensing. Can this be applied to mechas?"

"You mean, we should put the intelligent robot's sensing program on the mecha, so that the mecha driver can operate it through simulated sensing without any instructions?" Professor Qin said.

"Yes, this...is it feasible?" Yan Hao asked cautiously.

"In principle, it is feasible. The Mecha Research Institute has also studied it, but it is not possible with current technology." Professor Qin said, "Mechas are used for combat, and the sensitivity of their movements is very high, but the current sensing simulation technology is not yet mature. There is a one-second delay between the machine receiving a signal and responding. Even if the machine receives an instruction, it cannot be as sensitive as a human when making the corresponding action. On the battlefield, one second can determine life and death, not to mention that the movements of mechas are slow. Although the operation of the instruction is complicated, it can allow the mecha to respond quickly."

"So, as long as we solve this problem of slow reaction, it can actually be achieved on a mecha, right?" Yan Hao's eyes lit up.

"Yes, if this technology can be cracked, it will be a great boon for mecha pilots." Professor Qin said, "But the overall structure of the mecha is too complicated, and it is a historically difficult problem to make the mecha body simulate human movements through sensing and be as sensitive as the human body."

"I see."

"Do you want to study this?" Professor Qin asked.

"Yeah." Yan Hao nodded.

"Then keep going." Professor Qin patted Yan Hao on the shoulder and encouraged him, "The teacher has also done some research in this area. If you have any questions, feel free to ask me."

"Okay, thank you, teacher." Yan Hao's face turned red with excitement.
