When the last student in the laboratory left, Liu Fei, who had been sitting in the corner and pretending to sleep, stood up suddenly, his movements were unusually agile and vigorous, like a beast that suddenly woke up, it was just an hour, the chaotic laboratory had become orderly, all the instruments and equipment were wiped to shine, flashing with the unique luster of all kinds of metals, the windows were bright and clean, and even the ground was spotless.

This laboratory is located at the highest institution of Drow on Drow Star: Drow Mecha University.

However, although this luxurious laboratory is related to mechas, there are few truly formed mechas, because this laboratory mainly studies optical brains.

Liu Fei is not a student at Zall Mecha University, he is just a handyman with a low status, and his task is to clean up the laboratory every morning and evening, and of course, occasionally assist the professor with some manual work, such as carrying some bulky machinery and equipment.

Although Liu Fei has been working in this laboratory for two years, almost no one has noticed the existence of his handyman, and it seems that it is a matter of course that the messy laboratory becomes clean and tidy the next day.

……

For this job, Liu Fei is already familiar with the road, he can close his eyes and know where every tool should be placed, as long as any instrument is in his hands, he can find the first time it should be placed, in two years, he has never made a mistake, even if it is some complicated optical path parts, in Liu Fei's eyes are also well understood.

An hour and ten minutes later, Liu Fei had completed all the tidying and sanitation work in this huge laboratory.

Liu Fei raised his hand and looked at the old watch, today is slightly earlier than yesterday by seven seconds, he is very satisfied with this result, you know, through two years of optimization, even if it is a second ahead of schedule to complete the work is commendable, and today it is actually seven seconds ahead of schedule, which is enough to make him proud.

In 50 minutes, the door of the laboratory will automatically close, because Liu Fei's permission to clean the laboratory is only two hours, which is strictly controlled by the school's main control computer, and there will be no error. After shutting down the lab, the lab's defenses will activate, triggering an alarm for even a fly, and within a minute, heavily armed guards will arrive at the lab to catch the fly.

Of course, the closure of the laboratory can be brought earlier.

After looking at his watch, Liu Fei did not hesitate, entered his permission password, closed the thick steel gate of the laboratory, and then, like a gust of wind, slipped into the mecha modification laboratory next door.

In the mecha modification laboratory, inside the towering mecha, a strong, honest-looking teenager was busy sweating profusely, holding the cleaner clumsily with both hands, and there was a pitch-black oil stain on his face, which looked particularly embarrassed.

"Phineas." After the guy saw Liu Fei, he immediately breathed a long sigh of relief with a happy expression.

"Well, you rest for a while, I'll come." Liu Fei walked in front of the young man and took the cleaning instrument.

"Uh-huh, thank you Feige."

The young man nodded again and again, looking at Liu Fei's agile body with a smirk, he likes to watch Liu Fei's cleaning and tidying movements, just like dancing is full of rhythm, his hands are like full of magical magic, any tool can find its own suitable position in his hands.

The basic hygiene was quickly completed, and some tools began to be organized.

Armor plates, sensors, propeller shafts, engines...... Watching those cumbersome and complex tools and machinery return to their own places in Liu Fei's hands, the young man's eyes were filled with incomparable envy and admiration.

The boy didn't notice that Liu Fei was not only tidying up and cleaning, but every time a mecha part slipped in his hand, his eyes were filled with a kind of fanatical concentration, giving people the feeling that those mecha parts seemed to have life......

"This is the handle of the Starlight Mecha, which weighs seven hundred and thirty grams......"

"This is the auxiliary engine of the Warrior-11 mecha, weighing 5,600 grams......"

"Hey, what kind of engine is this?"

Liu Fei looked at a miniature auxiliary engine in his hand, this is an engine he has never seen, the engine is very small, flattened, less than one-fifth of an adult's fist, very light in his hand, less than three hundred grams, if it is not placed in the engine area, Liu Fei can't believe that this is a miniature auxiliary engine, in his memory, human beings have not developed such a miniature mecha auxiliary engine, after all, compared to the mecha that is often dozens of tons, the power provided by this miniature auxiliary engine is very limited.

Liu Fei resisted the urge to study carefully, put the engine away, and secretly memorized the number of the engine.

There wasn't enough time for him to take a closer look, and in ten minutes, the mecha lab would be closed.

Five minutes later, Liu Fei wiped the beads of sweat on his forehead, looked at his watch, and sighed secretly, today is eleven seconds later than yesterday, it seems that he can't achieve the ethereal realm without being affected by the outside world, it is obvious that his smooth movements just now have been interrupted because of the appearance of the micro engine, delaying time.

"Thank you, Brother Fei, you will definitely make a promise in the next life, hehe." The strong boy sneered.

"I've been talking about it for two years, can you get something practical?" Liu Fei said lightly.

"That'...... That...... Next month, I paid you a salary and invited you to a big meal. The young man blushed and said embarrassedly.

"Well, I hope it's not another nutrient solution." Liu Fei didn't seem to have any extravagant hopes between his tone.

"No, no, no......"

The young man laughed dryly, put his arm around Liu Fei's shoulder, and the two walked out of the laboratory shoulder to shoulder, laughing and leaving in the prompt that the laboratory was about to close.

At this time, it was already dusk, and the whole school had become quiet, and there was a feeling of emptiness, and the two crossed half of the campus and entered a lush wood.

This is a shortcut that Liu Fei occasionally finds, there is a wall inside the lush woods, and outside the wall is the slum where Liu Fei lives.

With the help of this shortcut, Liu Fei can save thirty-three minutes of his time.

The two men climbed a tree and fell from the branch to the top of the wall, and then to a branch outside the wall and slid down to the slum across the wall.

After sliding down the tree, the strong young man greeted Liu Fei and rushed towards a dense slum with an excited expression, his expression extremely excited.

Looking at the young man's disappearing back, a warm smile appeared on Liu Fei's indifferent face.

The strong boy was his only friend in the slums, surnamed Li Mingmeng, who was the same age as him, who had lost his relatives since he was a child and grew up in the slums.

Li Meng and Liu Fei's interests are very different, Li Meng likes ancient martial arts very much, his biggest dream is to earn enough money to practice ancient martial arts, there is a very magnificent name in the slum "Zhenyuan Universe Martial Arts School", it is said that Zhenyuan Universe Martial Arts School has experienced glory in the chaotic era of cosmic migration, and then gradually fell for various reasons.

Although the Zhenyuan Universe Martial Arts School has been relocated to the slums, and the fees have become extremely low, for the orphan Li Meng, the cheap tuition fee is still astronomical.

According to Li Meng's concept, it will take at least two years for him to earn enough tuition and living expenses for three years, after all, if he enters the martial arts school, he will have to give up the cleaning job at Zall University, and he needs not only a tuition fee, but also three years of living expenses.

Li Meng's daily life is very simple, after finishing the school's work, he will rush to the Zhenyuan Universe Martial Arts School, stand on the edge of the pitifully small martial arts field to observe, trying to steal a little legendary martial arts secrets.

Li Meng is most fond of peerless martial arts such as the Great Shift of Qiankun and Jiuyang Divine Skills, and he has mentioned to Liu Fei more than once the virtual kung fu in those ancient martial arts novels, saying that if the magic is practiced, he will walk the rivers and lakes, act chivalrous, punish evil and promote good.

In the face of Li Meng's fanaticism, Liu Fei could only smile bitterly, he wanted to tell Li Meng that those magic skills were just the martial arts that were imagined by human beings who were called "writers" in the ancient earth when they were idle, but Li Meng was deeply poisoned, and he was convinced of those magic skills.

After watching Li Meng's back disappear into the intricate alleys of the slum, Liu Fei also quickened his pace and hurried towards his residence.

Like Li Meng, Liu Fei also has his own dreams.

Liu Fei's dream is to enter Zall Mecha University, and he is most interested in mecha.

Cleaning work in the optical path and optical brain laboratory is the most painful thing for Liu Fei, except for the optical path and the optical brain, Liu Fei is interested in almost all courses about mechas, however, he was arranged in the optical path optical brain laboratory......

Li Meng still has two years to enter the martial arts school of his choice, while Liu Fei is much longer, the tuition fee of the Zall Mecha University is tantamount to an astronomical amount for Liu Fei, and it is basically impossible for a poor person with a humble status like Liu Fei to enter the highest school in the Drow Star Domain.

Of course, there is no need for Liu Fei to worry about this, because, according to the school rules of Zall Mecha University, as long as Liu Fei has worked in Zall Mecha University for three years, he will be qualified to enter Zall Mecha University, which is a school rule personally promulgated by the second president of Zall Mecha University, in order to reward poor children who have contributed to the school.

Out of humanitarianism, and out of the desire to give the children at the bottom the opportunity to enter the highest schools in the Drow system, or to gain some good reputation for the school, the Drow Mech provides a job for the young people of the slums every year, providing them with access to the school.

In fact, there are many children in the slums who enter the Zall Mecha University through this way, but this proportion is very, very small, because, even if the Zall Mecha University waives a large part of the tuition fees, as children in the slums, it is still difficult to bear the huge expenses of the school, and more children in the slums only use three years of work as a means to make a living.

According to the statistics provided by the school, in the past 20 years, only five children from the slum have entered school, and one of them has benefited from the support of teachers, while the real data is that only one of these five children has been able to complete four years of college, and the remaining four have dropped out for various reasons......

The students who were able to enter the highest universities in the Drow galaxy all had prominent family backgrounds, both materially and spiritually, and had a sense of superiority that ordinary people did not have.

Liu Fei doesn't care about the discrimination of students, what he cares about is entering the university and getting in touch with more knowledge about mechas.

There is still one year left, Liu Fei will have the qualifications to enter the school, however, Liu Fei's savings are less than half of the tuition fees, however, Liu Fei is not worried, because, two months ago, he found a way to make money.

After a dash of running, Liu Fei returned to his residence, which was more of a mecha than a residence.

This is an abandoned ancient mecha, the mecha is a standard twelve meters, weighing seventy tons, it looks extraordinarily bloated, it stopped production half a century ago, in the slums, there are many houses modified with this kind of mecha, and it has become a unique scene in the slums.

More than a hundred years ago, the Drow galaxy suffered a large-scale alien attack, the scope of the Drow Mecha University is one of the main battlefields on the ground, it is said that the battle between humans and aliens lasted for fifteen years, and the population casualties were as high as two billion, which was the largest and most tragic war after human beings entered the universe, and it was also that war that completely collapsed the original political system of mankind, ushering in the era of terrifying cosmic warlords, and also ushered in the era of mecha......
