Qiao Yu, under the leadership of Dana, soon arrived at the destination, Fengchen's repair shop.

Located on the edge of the business district, the main business of this repair shop is to repair all kinds of daily machinery, household robots, hovercars, personal terminals, etc., and the maintenance items can be described as varied. As a teacher at the God of War Academy, Fengchen naturally couldn't stay in the maintenance shop all day, and this shop was managed by a few professional maintenance engineers hired by Fengchen on weekdays. As the boss and chief repairer, Fengchen will only come to deal with the problems that the maintenance engineer in the store can't solve, and only these difficult problems may bring inspiration to Fengchen.

Later, Fengchen found a new purpose, that is, to train students that he could admire. Although the theoretical knowledge that cadets can obtain in school is abundant, the basic knowledge taught in military academies is the mechanical theory and maintenance knowledge of weapons and so on. The advantage of this is that the cadets can master the skills they need to master in the future service in a short period of time in the academy, but for some elite cadets and geniuses, more comprehensive and extensive knowledge and solid basic theories will enable them to achieve greater achievements in the future.

Although Fengchen was not prepared to train these students, who were destined to become elite fighters in the Imperial Army, into specialized mechanical maintenance experts, he always believed that weapons, no matter what they were, were equivalent to second lives for the soldiers who wielded them! How can a person not understand his second life? If this second life is damaged, sick, old, and outdated, does the warrior have to rely on someone else to deal with it? So with such a weapon, can a warrior entrust his life to it?

Therefore, although mechanical maintenance and design seem to be scientific research skills that need to be mastered by researchers, Fengchen believes that a strong warrior must have a certain level of proficiency in this. Therefore, he often invites some students to work in his own repair shop, and does not tell his true thoughts, and how much students can learn here depends on the students' own efforts.

Of course, today is very special, Fengchen is waiting in the repair shop, because he and Qiao Yu have made an appointment to meet here. Perhaps because Qiao Yu inadvertently indirectly defended his home planet, Fengchen attached great importance to this student who was born as a civilian, and through a week of observation, he found that Qiao Yu was very active in absorbing all kinds of knowledge, and almost soaked in the library in his spare time, which was very rare for the students of the mecha department, and they thought that as a future star knight, combat skills were the most important.

What these young warriors lack is not the belief in what they are fighting, but the ways and experience of how to fight. The accumulation of combat experience can only be relied on by oneself, while the ways and methods of combat can be mastered by studying. More fighters focus on their own physical training, combat skills and military skills, but often ignore the mechanical technology itself.

As a Fengchen who has fought on the front line for a long time, he knows very well that combat skills are important, but in some difficult situations, some skills that seem to be unrelated to combat may become the key to saving lives.

Dana pushed the door and walked into the repair shop, "Teacher Fengchen, is Teacher Fengchen here?" Someone is looking for you. As a second-year student of the God of War Academy, of course Dana also knows Li Fengchen, and as an excellent student, Li Fengchen is also very concerned about her, but the commander of the battleship really does not need special training in mechanical maintenance - the maintenance and design of the battleship and the design of small machines and mecha are completely different, and it is not just one or two people who can understand the complete technology. Battleships are often divided into multiple maintenance groups to maintain each module of the battleship, and as a student of the battleship command department, as long as you can understand the functions of each module, you can roughly understand the principle of its operation, which is quite remarkable.

Qiao Yu followed Dana into the shop of the repair shop, which is a place to discuss business with customers and rest for maintenance technicians, and the real maintenance needs to be carried out in the maintenance workshop behind the store.

I saw that Li Fengchen was wearing a slightly worn engineering maintenance uniform, although it was even worn white in many places, but the clothes were very clean. Qiao Yu was very surprised by Li Fengchen's simple clothes, but Dana didn't seem to be surprised.

"Huh? Dana, why are you here, and you still brought Qiao Yu with you? I remember that I only invited Qiao Yu to come over today. Fengchen was slightly surprised when he saw the two people in front of him.

"Ha, I picked up this lost junior brother on the street in the business district, and I brought him to you~" Dana explained to Fengchen with a smile.

"Aha, that, Mr. Li is like this, the electronic navigation system of my personal terminal may be a little damaged......"

"Oh? Is there a data defect in the personal terminal? You can try to re-download the electronic navigation information on the Internet. ”

"Ah, yes teacher, I ...... I went back and went online to download the navigation information again. ”

Fengchen didn't pay attention to this trivial matter, "Since you're here, you must have seriously considered my suggestion, right?" ”

"Yes teacher, I'm going to learn more about mechanical maintenance in your shop."

"Very well, in that case, I'll talk to you about the next study plan."

Dana saw that the two of them had entered the state, so she offered to leave, "Then Mr. Fengchen, I will go to the academy first." Junior Brother Qiao Yu will also see you again, right? Dana waved to the two of them and turned to leave the repair shop.

"I specially called you here today to talk to you about my research direction." Fengchen motioned for Qiao Yu to sit on the sofa.

"First of all, the mechanical maintenance and design I studied are mainly related to mechs and mecha weapons, after all, you should have heard that I used to be a star knight in the past."

"Yes, teacher, I heard of your name on the first day I came to God of War. You are said to be known as the Hero of the Storm on the front lines. ”

A smile flashed on Li Fengchen's face, everyone liked to listen to flattery, let alone from the mouth of the student he fancied. "That's all in the past."

"I'm working on a kind of mecha research right now, and in fact, many research institutes in the empire have related projects, but maybe I'm one of the most active people on this project. As someone with personal combat experience, I don't have any doubts about the combat power of mechas, but mechas, especially the higher the level of mechas, are extremely tedious to wear and tear in battle, and repair and maintenance in non-wartime. ”

"Take the M1 type mecha equipped by the current Imperial Cadet Knight, this is already the lowest level of mecha equipped by the Imperial Army, and its mecha arm, in order to maintain strength and stability, includes 12 basic mechanical structures and hundreds of mechanical parts. The wear and tear of daily training, the intense attrition of combat, the life of a mecha arm can last about 2-3 years in non-war time, and once the war is fierce, even if the mecha arm itself is not damaged, the severe wear and tear will greatly reduce its lifespan, and it is often necessary to replace a mecha arm in a few months. This is not only a heavy pressure on the logistics of the front, but also a very dangerous thing for the knights who are fighting on the front line. ”
