The battle ended with the embroidery needle-111 being captured and the driver dying, as for the fate of the blue and white mecha, it is impossible to know, however, Liu Fei judged that the embroidery needle-111 was originally in the chaotic meteorite flow, with the driver's amazing sniper marksmanship and speed, he could completely take advantage of the chaos to escape, but not only did he not escape, but went deep into the encirclement to snipe the enemy, obviously, he was covering the blue and white mecha to escape.

Did the blue and white mechs escape?

No one could answer Liu Fei's question, but Liu Fei was sure that the blue and white mecha had been severely traumatized, because the meteorite vortex generated by the sudden meteorite explosion at that time enveloped the blue and white mecha in it, and it was impossible not to be traumatized......

……

The appearance of the embroidery needle - 111 did not affect Liu Fei's life, Liu Fei still got up early every day to go to work to help Li Meng complete his work, and in his free time, he used some equipment and instruments to do some things that he was interested in.

The embroidery needle mecha changed Liu Fei, at least, Liu Fei's carving time is getting less and less, unconsciously, Liu Fei began to pay attention to some information about advanced mechas, but unfortunately, Zall Mecha University is only a scientific research institution, although it has some advanced instruments and equipment, mainly to learn and master some basic knowledge of mecha, and does not develop and produce mecha, if you want to get in touch with the embroidery needle - 111 is as advanced as the mecha is impossible.

Liu Fei has always been a little puzzled why a high-end mecha like the embroidery needle-111 appeared in the mecha laboratory, and at the same time, there was also a miniature auxiliary engine.

Liu Fei's understanding of mecha is very confusing, because he has never received a systematic education, he is completely exploring and learning by himself, and it is only so far that Liu Fei has only come into contact with two subjects about mecha, the optical brain optical path and the mecha laboratory.

In fact, these two laboratories are only one of dozens of laboratories, for example, there are five laboratories about the optical path of the optical brain, and the place where Liu Fei works is just one of them, and the main test topic is the test between the optical path of the optical brain and the sensor.

The mecha laboratory where Li Meng works mainly studies the mechanical part of the mecha.

Under the constraints of this environment, it is difficult for Liu Fei to establish a complete knowledge system about mecha in his brain, which is also the main reason why he wants to enter the Zall Mecha University, only by becoming a student of the school, can he freely enter and exit all the laboratories of the school, of course, the key is that the mecha pilot training room and martial arts attract Liu Fei.

In fact, Li Fei is not interested in the research of mechas, but in piloting mechas, and after being in the laboratory for a long time, it is impossible to have the opportunity to fly mechas, let alone conduct mecha shooting and combat training.

As an institution of higher learning with more than 30,000 students, Zall Mecha University has a strong faculty, and some subjects are also very carefully detailed, covering all disciplines related to mecha.

Mecha is generally composed of an actuator, a driving device, a detection device, a control system, and a complex machine.

Compared with civilian mechas, military mechas are more complex, and they also have complex weapon systems.

Simply mentioning some of them here is enough to feel how complex the disciplines involved in a mecha are. The actuator is the mecha body, and its arm generally adopts a space open-chain linkage mechanism, in which the motion pair is often called the mecha high-tech product joint, and the number of joints is usually the number of degrees of freedom of the mecha. According to the different types of joint configuration and motion coordinates, the mecha actuator can be divided into Cartesian coordinates, cylindrical coordinates, polar coordinates and joint coordinates. For the sake of anthropomorphism, the relevant parts of the mecha body are often referred to as the base, waist, arms, wrists, hands, and walking parts......

Of course, most students can ignore more than 99% of the information, but the basic configuration data such as the cockpit, engine, and optical brain energy cten that are directly related to the operation of the mecha need to be mastered by students.

To put it simply, the mecha university is like the driving school of the home planet earth, the difference is that the driving school of the home planet earth only learns basic driving techniques and safety rules, while in the mecha university, you also need to understand some basic principles of mecha, and even learn to deal with some simple faults, after all, a car walking on the ground and a mecha flying in space cannot be compared at all, the car breaks down and abandons the car or the repair shop, and if the mecha breaks down in the vast interstellar space, There is only one way to die!

As a student of Zall Mecha University, except for some professionals, most of the students have to learn driving skills, and it is unthinkable that they will not be able to fly mecha in this cosmic era.

Liu Fei's theoretical knowledge of mecha surpasses that of most students, but he lacks the practical experience of ordinary students.

As early as when Liu Fei was five years old, Liu Fei had been exposed to the knowledge of mecha from various magazines and newspapers, and as he grew older, under the compulsion of the soldering iron, Liu Fei read a lot of books about mecha.

However, in the massive amount of knowledge, because of the constraints of the slum environment, Liu Fei's knowledge system has not yet been formed, it is only on paper, and the contact area is very narrow, except for the mecha of the Zhuoer Star Domain, there is almost no involvement in the mecha of the other six star domains, and the embroidery needle-111 can be said to be Liu Fei's first real contact with the mecha of the outside world.

The black melee mecha also opened Liu Fei's eyes.

The most important thing is that Liu Fei knows that in this world, there are still many mechas that he doesn't know, at least, he has never heard of the black melee combat mecha, and the operation skills of the mecha are even more memorable.

The appearance of the hologram of the embroidery needle - 111 and the melee combat mecha made Liu Fei understand a truth, a good pilot is more important than an advanced mecha in battle.

Interstellar sniping and hand-to-hand combat also entered Liu Fei's field of vision for the first time!

Today, Liu Fei completed all the work early, and for the first time, he did not stay in school, because he had more important things to do today.

During this time, Liu Fei's whole person was addicted to the battle hologram, which was repeatedly played by him, and every time he watched it, he would have different feelings and gains, and the amazing shooting of the embroidery needle-111 and the mysterious disguised action of the black melee combat mecha made him fascinated.

In this case, Liu Fei has not gone to Cheng's wood carving for a week to deliver.

The wood carving of the "Eagle Spreading Its Wings" has been completed and must be delivered today.

Wrapped up the wood carving out of the door, through the Fallen Street straight to the pedestrian street, the pedestrian street at night is brilliantly lit, and the endless flow of people makes the street full of surging vitality.

When Liu Fei strode to the door of Cheng's wood carving, he was dumbfounded, the antique wooden door of Cheng's wood carving was closed, and no one could be seen from the transparent glass.

What happened?

In Liu Fei's memory, Cheng's wood carving has never been closed, rain or shine.

What's going on?

"Liu Fei, you're here." A voice sounded behind Liu Fei.

"Hmm." Liu Fei turned around, it was Xiao Zhao, an employee of a clothing store next door, Xiao Zhao liked to sit in the wood carving shop when he was fine, chatted with Chenchen, and was also familiar with Liu Fei.

"Chenchen, let me tell you, the wood carving shop can't open for the time being." Xiao Zhao's expression had a hint of sadness.

"What happened?" Liu Fei felt the sadness in Xiao Zhao's eyes.

"Cheng Laohe...... He's not in good health......"

"In that hospital?"

"Internal Medicine Inpatient Building, 43rd Floor, Ward 27, Zall Mecha University Hospital......"

……

The Affiliated Hospital of Zall Mecha is next to Zall Mecha University, of course, this "side" has to be put in quotation marks, because Zall Mecha University itself covers an area of nearly 10,000 acres, and the hospital covers an extremely vast area.

In the battle with the aliens, the Zall Mecha University was able to survive thanks to the Affiliated Hospital of the Drow Mecha University, because, at that time, the battle in the Drow Star Capital Circle was in white heat, the battle was unprecedentedly fierce, and the casualties were particularly serious, so the hospital for treating diseases and wounds became a key protection object.

It is said that in the battle to defend the school at that time, the military dispatched the most elite mecha troops to be stationed at the Dall Mecha University, and the slum next to the Drow Mecha University was the battlefield of that year.

Liu Fei is not a person who understands the world, but Cheng Lao is half of his teacher, and Liu Fei still decided to take a look.

Gently pushed open the door of the 27 ward, this is a separate ward, the environment is quite good, the room is very quiet, Cheng Lao closed his eyes, his expression was very peaceful lying on the bed is infusion, all kinds of instrument lines are connected to his body, the instrument flashes red, green and green flashing indicators make the peaceful room add a sense of tension and depression.

Chen Chen leaned on the edge of the bed with a haggard face, his smooth cheeks had lost their redness and turned into a miserable white, when he saw Liu Fei come in, Chen Chen stood up, grabbed Liu Fei's arm, and walked out lightly.

"What's wrong with Cheng Lao?" When the door closed gently, Liu Fei asked.

"Grandpa, he ......" Chenchen's body twitched suddenly, tears flowed silently, and a pair of hands stirred the corners of his clothes.

Liu Fei didn't continue to ask again, there is no doubt that Cheng Lao's body has a very serious problem, otherwise, Chenchen would not be so heartbroken.

The huge corridor was empty and extremely quiet, looking at Chenchen who was crying, Liu Fei didn't know how to comfort him, so he could only look at this weak girl quietly.

"Thank you for coming to see my grandfather." Chenchen quickly regained his composure, and said softly.

"Hmm."

"My grandfather has something to say to you."

"Okay."

"We're waiting for him here."

"Okay."

……

The two sat down in the chairs they had rested in the hallway and fell silent for a while.

Liu Fei has experienced the serious illness and death of the soldering iron head, so he naturally knows Chenchen's mood, but for Liu Fei, who is silent, it is really not an easy job to comfort people, so he simply kept silent.

Chenchen is also a girl who is not good at words, neither of them speaks, and the corridor is so quiet that it can be heard that a needle is dropping, but Chenchen seems to have something to say, and he wants to speak a few times and stops.

"Cheng's wood carving is going out of business." Finally, Chenchen spoke.

"Why?" Liu Fei was stunned, his tuition still relied on the small wood carving shop!

"Grandpa...... He ...... "Chenchen's tears couldn't be held back again.

"I understand." Liu Fei's mood was a little heavy, not only for tuition, but also for Cheng Lao.

"The wood carving shop has a history of more than 300 years, and in the migration war, Sudoku was closed, but it still survived, and this time it ......" Chenchen's tone was endless loss.

"You can drive it too." Liu Feidao.

"Me?!" Chen Chen smiled bitterly: "I might as well close the door if I open it, it will only disgrace the signboard of 'Cheng's Wood Carving'." ”

“……”

Liu Fei opened his mouth for a moment and didn't speak, he knew that Chenchen's talent in wood carving was simply a mess, and it was obviously unrealistic for her to run a wood carving shop.

"Didi ......" A slight alarm sounded in Chenchen's hand, it was a pager.

"My grandfather woke up."
