"Sorry to excuse me!"

Su Zijing seemed to be too involved and didn't react at all, and Liu Fei had to take a step closer to increase the volume.

"Ah...... What are you doing? ”

Su Su woke up suddenly, looked back, and saw that Liu Fei was almost behind her, and couldn't help but stand up from the chair in fright, and subconsciously looked around, and found that she and the cleaner in front of her were left in the huge laboratory, and her face suddenly showed a trace of panic.

"I don't do anything, I'm just reminding you that class is over!" Liu Fei took a step back and kept his distance from the woman, who emitted a strange fragrance that gave him a strange feeling.

"So what?" Su Zijing saw Liu Fei take a step back before she breathed a sigh of relief.

"You can leave."

"Really...... However, there was still more than an hour left before the end of class. Su Zijing looked at the time displayed on the light brain and frowned.

"They're all gone." Liu Fei said expressionlessly.

"You want me to leave?" Su Zijing suddenly smiled softly.

"Yes." Liu Fei nodded.

"Ahem......" Su Zijing didn't expect Liu Fei's answer to be so direct, so she hurriedly coughed to hide her gaffe.

"However, I still haven't finished the test, sorry." Su Zijing calmed down, her smile disappeared, replaced by cold arrogance, and sat down on the chair again.

"......" Liu Fei opened his mouth, unable to speak.

"It'll be fine soon."

Seeing Liu Fei's sluggish face, Su Zijing actually had a trace of inexplicable happiness, of course, Su Zijing didn't understand the reason, you know, Su Zijing has been surrounded and flattered by the stars for a long time, few boys will be as indifferent to her as Liu Fei, seeing Liu Fei eating deflated, he will naturally be happy, which is a very common thing in psychology.

Soon, Su Zijing forgot about Liu Fei's existence and once again devoted herself to the test.

Time passed little by little, and Liu Fei stood motionless behind Su Zijing like a stone sculpture.

"Sorry to disturb ......" Twenty minutes had passed, and Su Zijing's work didn't seem to have made the slightest progress, and Liu Fei finally couldn't help it. For him, this is a huge waste of time, the soldering iron head said that wasting time is tantamount to making money and killing people, Liu Fei has a very strong concept of time, everything is arranged in an orderly manner, and he will never waste the slightest time.

"Don't bother me." Su Zijing immediately interrupted Liu Fei's words, she was not in a good mood, this was her twenty-third optical path test, and she was always unable to find the cause of the optical path failure.

"The resistance of the photoelectric circuit depends mainly on the contact resistance between the dynamic and static contacts of the circuit breaker. The existence of contact resistance increases the loss of the conductor when energized, and the temperature of the contact increases, and the size of its value directly affects the current-carrying capacity during normal operation, and affects the cutting ability of the short-circuit current to a certain extent. Therefore, the value of the conductive circuit resistance tester per phase of the circuit breaker is an important data for the installation, maintenance and quality acceptance of the circuit breaker......"

"Ah......" Su Zijing looked at Liu Fei blankly, with an incredible expression.

"I don't mind helping you with the test."

Liu Fei was asking for Su Zijing's opinion, in fact, he had unceremoniously pulled Su Zijing away with the chair, and a pair of hands jumped quickly on the main control board of the light brain, full of rhythm, the indicator light on the instrument kept flashing, and the data stream on the holographic screen was leaking wildly......

Two minutes later, a copy of the test path data report was spit out of the machine.

"Alright, you can go."

"Oh." Su Zijing was still sitting on the chair, immersed in shock, if it weren't for the text in her hand, she couldn't believe what was happening in front of her just now, she spent an afternoon on the test work that she hadn't completed, and this cleaner only took two minutes to get it.

Subconsciously, Su Zijing pinched her fingers, and only after feeling the pain did she realize that she was not dreaming.

I'm a top student!

Looking at Liu Fei, who was busy manipulating the cleaning equipment, inexplicably, Su Zijing felt a sense of frustration, and her self-esteem was seriously hurt.

"You can go!"

Just when Su Zijing was still unable to extricate herself from frustration, Liu Fei had already completed the cleaning of this piece.

"Oh......"

When Su Zijing walked out of the door of the laboratory, Liu Fei almost immediately closed the steel gate of the laboratory and went straight to the mecha laboratory next door, leaving Su Zijing standing in a daze in the cold metal corridor......

What Su Zijing thinks has nothing to do with Liu Fei, Liu Fei cares about the mecha in the mecha laboratory, in his eyes, Su Zijing, the first beauty of Zall Mecha University, is not as attractive as a composite armor plate.

Like the Light Brain Laboratory, the larger mecha laboratory has also become empty, leaving Li Meng busy driving some loading and unloading equipment.

"Aha! Phineas came just in time......"

"You can do it yourself, I'm going to do something."

"Oh." Although Li Meng was dissatisfied, he was helpless, after all, he now had a lot of time to squander.

Liu Fei went straight to a mecha with a whole body of blue, this mecha was only shipped a few days ago, Liu Fei has not had time to study, and today he finally found an opportunity.

The height of the mecha is eleven meters, which is a little shorter than the standard mecha model of twelve meters for humans, and it is known from the exposed Senran muzzle of the mecha that this is not a civilian mecha, but a long-range combat mecha, however, this mecha looks very delicate, lacking the hideous and heavy feeling of the Drow galaxy combat mecha, overall, it makes people feel light and fluttering.

It's clear that this isn't a mainstream mech in the Drow system.

Although the scientific and technological civilizations of the seven major galaxies all originated from the home planet Earth, after experiencing the great era of interstellar migration and the current interstellar warlords, they are fighting their own battles, and the mechanical civilization has also ushered in an unprecedentedly active situation in which a hundred flowers bloom and a hundred schools of thought contend.

As one of the favorite humanoid weapons of mankind, the mecha is also naturally colorful, due to the different environments and aesthetics of each galaxy, the mecha also has obvious regional colors.

Among the seven major galaxies, the Drow Galaxy has the most powerful style of battle mechs because of its proximity to the alien star, and compared with the mecha of the six major galaxies, the mecha of the Drow Galaxy is much larger in terms of weight and volume.

Liu Fei's understanding of mecha is limited to his understanding of the mecha of the Drow Galaxy, because it is difficult for Liu Fei's economic level to contact the mecha of other galaxies, and the laboratory of Drow Mecha University rarely appears in the mecha of other galaxies, which causes Liu Fei's understanding of mecha to be single.

This blue mecha that looks a little elegant and agile is covered in scars, and there is a wound on the right mechanical arm, which cuts off the lower part of the mechanical arm, revealing the complicated light path inside, and above the cockpit, there is also a shocking wound, from which the main control board in the cockpit can almost be seen......

Undoubtedly, this is a mecha that has survived a terrible battle.

Because of the experience of the miniature auxiliary engine, Liu Fei did not hesitate at all, picked up the light ruler and recorder and climbed onto the cockpit of the mecha.

The data of any mecha can be obtained from the main control light brain of the mecha, the difficulty is that the light brain of the mecha has set permissions, and it is not just a random person who can obtain the data of the mecha, of course, that refers to the core data of the mecha, in fact, most of the data of the mecha is open on the light brain.

"What a luxurious cockpit!"

When Liu Fei entered the cockpit, he was immediately amazed, compared with the simple style used by the Drow Galaxy, the cockpit of this mecha can be described as extravagant.

Wide and comfortable leather driver's seat.

Large-size holographic screen and multi-function holographic scanning system.

All-round hydraulic protection system.

Automatic manual transmission.

Refrigerators, ovens, and life cycle systems are all available.

……

It's a moving room, not a battle mech, and the meticulous workmanship of this mech is more than a cut compared to the drow's rough mech-making process.

Just at a glance, even Liu Fei, who claims to be a layman, can see that the manufacturing process of this combat mecha is far ahead of the combat mecha of the Drow Galaxy.

Judging by Liu Fei's eyes, this mecha should be quite excellent in terms of flexibility, but there is a considerable gap compared to the mainstream mecha in the Drow galaxy in terms of defense, at least, its light armor body is obviously designed to be extremely weak, and if it is hit, it will be very likely to be fatal. Because of its weight, although it is extremely explosive in a short range, its long-range ability is definitely not good because its capacity is not enough to carry enough energy, which is already at a disadvantage in today's space battles that can easily travel hundreds of thousands of kilometers......

In fact, the severed robotic arm and the shocking wound on the cockpit have proved Liu Fei's speculation that the possibility of such an important position as the cockpit being penetrated is very unlikely to appear on the mecha of the Drow system, because any mecha of the Drow system spares no effort in the armor protection of the cockpit.

Although the cockpit was violently damaged, and even there were stains of blood on the cockpit, the internal structure of the cockpit was still basically intact, and the optical brain could also be opened.

Of course, this has made Liu Fei very satisfied, at least, he doesn't have to climb up and down for the height and weight of the mecha, from the preliminary data provided by the light brain, Liu Fei can intuitively understand the basic structure and performance of the mecha......

Soon, Liu Fei had already determined that this was a mecha from the Pangu Galaxy, with a very unique and weird name, called "Embroidery Needle-111 Type".

The Embroidery Needle - 111 is a fairly advanced mecha, and the data shows that the scanning system of the embroidery needle is at least ten years ahead of the scanning system of the Drow galaxy mecha.

In the vast interstellar war, whether it is a space battleship or a battle mech, having an advanced scanning system is equivalent to grasping the initiative in the war.

The engine power of the embroidery needle-111 is also very powerful, and its maximum speed is almost nearly one-fifth faster than the mainstream mecha of the Drow Galaxy, which is a very remarkable data, you know, the development of the main engine of any mecha has gone through hundreds of years of history, and the gap between the seven galaxies is not obvious, let alone one-fifth, even if the speed is increased by every second, it is also commendable.

Of course, in addition to the powerful engine power, the main reason for the powerful speed of the embroidery needle-111 is to sacrifice the armor protection of the mecha, and Liu Fei believes that this sacrifice is not advisable.

Embroidery needle-111 There is another place that amazes Liu Fei, that is, the sensors all over the body of the mecha, you know, there are only six sensors on a "Hawkeye" unmanned reconnaissance ship, and the sensors all over the body of the mecha are enough to show that the Pangu Galaxy has made great progress in the development of mecha sensors, if you follow the concept of the more sensors on the reconnaissance ship, the more expensive the more, there is no doubt that the value of this mecha is extremely high......

As time passed little by little, Liu Fei was fascinated by the study of the functions and functions of every part of this mecha, even its material.

Liu Fei, who understands the art of wood carving, knows that whether it is wood carving or mecha, its value depends on the material on the same process requirements.

In the past few months of contact with wood carving, Liu Fei has deeply felt the importance of materials, and the value of a piece of wood carving made of colorful rosewood is dozens of times or even more than that of ordinary wood carving.

Compared with the material of wood carving, the battle mecha has higher requirements for the material, and a mech using high-quality alloy armor plates will definitely have a higher survival rate on the battlefield than a mecha using ordinary metal armor. There is no doubt about that.

Because he did not have enough access to the advanced metal analyzer that could be moved, Liu Fei had to use an alloy blade to scrape the metal powder on the parts of the mecha, and then use the metal analyzer to analyze the ......

The data shows that the material of the embroidery needle-111 is average, except for the use of rare metals in some important parts, there is nothing special, if this mecha is the mainstream mecha of the Panlong Galaxy, then it means that the Panlong Galaxy has lagged behind the Drow Galaxy for at least twenty years in the research and use of metal.

……

"Liu Fei, someone is here."

Li Meng's hurried call came from under the mecha, Liu Fei did not hesitate at all, his agile body quickly climbed down from the cockpit, and the moment he left the cockpit, he did not forget to turn off the light brain.

"It's this mech."

As soon as Liu Fei's feet landed, a group of big men in suits with cold expressions strode in, and this group of big men with cold expressions didn't notice Liu Fei in the cleaner's uniform at all, and immediately dragged the embroidery needle-111 away with equipment, the action was clean and neat, without the slightest drag, and the work efficiency was very high, and at first glance he was a well-trained person.

Soon, a group of big men dragged the mecha and disappeared, leaving Liu Fei looking at the empty mecha position in a daze.

"What's wrong?" Li Meng walked over and asked.

"It's okay, let's go."

Liu Fei exhaled a long breath, fortunately he had the foresight to copy the basic data of the embroidery needle-111 with a recorder.
