The Soyuz star is on the edge of the Tianhe system, and she has no satellites, but humans have built a huge artificial satellite, the interstellar train orbital station, which is called the crescent. The Alliance Star is the core of the human race, a huge system with one star and sixteen planets, beyond the scope of the Alliance Galaxy, and the twelve survival star fields of human beings, which are occupied by the twelve nobles, and together they are a larger human survival system.

The alliance of all the families, plus the humans in the core star field of the alliance, formed the Great Alliance of Humans.

The orbital station of the Alliance Star is the largest orbital station of the Human Alliance, and more than a hundred interstellar trains can be parked here at the same time, each of which is tens of thousands of meters long. Each track is thousands of kilometers long, and it is not only a stop for interstellar trains, but also a maintenance, overhaul and assembly station, and it is incomparably small in the spectacle of their own construction.

The interstellar trains of the Human Alliance's trunk line must depart from the Soyuz Star Orbital Station, and after a week's time, they will arrive at the transit hub of the Human Alliance-Laihui, which is the name of a planet, in fact, it has another name - interstellar springboard. The shuttle star is the last stop on the main line of the Alliance's core system, and most of the goods and passengers from all over the Alliance's core board the train here, from here, the trunk train will enter a long interstellar journey, so it must be replenished with adequate supplies.

There is no air, no water, and the gravity is very weak, but there is a location advantage, and no matter how many cargo personnel are concentrated here from the feeder transportation system, it will not affect the order of the Alliance Star.

The Wasteland is parked at one of the platforms of the Orbital Station, and tomorrow it will embark on an even longer journey, and perhaps even its captain will forget that this is the first time it has run. The people and goods that had converged from the feeder line had to be loaded in order, and the Wasteland was about to embark on a new journey, perhaps it would be its last journey, but everything was going on as before, meticulously.

"Isn't it okay yet, how long will you have to go?" A strong female voice roared.

This is a middle-aged woman with a fortune, the anxiety of travel makes her face look tired, and her hair is dull and messy, and she should be a rich person in her clothes, because the level of this cabin is not low. The woman's neck and hands are covered with ornaments adorned with huge gems, which shine in the reflection of the light, but the combination reveals a greasy atmosphere.

Obviously, this is a nouveau riche who came from nowhere, if such a dress is seen by those real noblewomen on the alliance star, they may not bother to ridicule, especially the noble women who can get close to the twelve families, this image can disperse them from afar, the clothes are not as bright as possible, and the gems are not everywhere to be noble, their confidence is different, not to mention the twelve nobles, they all have more than a dozen planets in their families, and they don't need to be superficial, these, the nouveau riche don't understand.

"Ma'am, it'll be all right soon." A young man poked his head out of the hatch, "You don't have to worry, the train will leave tomorrow, so let's use plenty of time to repair your toilet, you must know that this is not a technical problem, it just takes a little time, to be honest, the age of this train is a little older, my age multiplied by five may not be as big as it......"

"You damn maintenance man, do you mean I'm old?" The female voice roared.

"Certainly not, ma'am." The young maintenance worker hurriedly said, "I can understand your feelings, this is an anxiety disorder in the face of lonely travel, in fact, everyone has it, I'm just used to it, do you know what is the most important thing in interstellar travel?" ”

"And what do you say?"

"Motivation, ma'am, this is your first interstellar trip, right?" …,

The young man explained: "If your toilet breaks, you can survive with many solutions, because you know that everything will come to an end, and when you get out, you will face another good life, and it is only a short trip." If there is a problem with the power, we will float in this space for the rest of our lives, with nothing, and become the garbage of the universe. ”

The lady's voice was silent for a moment, obviously frightened, and then asked, "Motivation, did I buy a ticket to suffer a crime?" ”

The young man said: "How come, it's just that considering the age of this train and the harshness of the interstellar journey, it's good to be able to reach the destination alive, have you seen this bright starry sky?" They are as bright as gems, but in fact they are too far away from us, and interstellar travel has to be in the dark universe most of the time, where it is dark and cold, infinitely close to the state of vacuum, there is nothing, how to cross without motivation, don't you say it is not easy...... Ah, ma'am, this toilet seems to have been repaired! ”

"Really?" The woman's voice softened a lot, "Then go ahead, don't make any mistakes, the old lady doesn't want to wait for death in that empty universe, she can't even use the toilet, this is actually a damn upper class!" ”

"My name is Qin Guan, and the maintenance staff of No. 4597 of the wasteland team is here for you, madam." The young man said with a grin.

Suddenly, the communicator on his wrist sent out a prompt, which was a signal that only high-authority people on the train could send, and Qin Guan paused for a moment to connect the communication: "Hello commander, the maintenance staff of the No. 4597 maintenance squad of the wasteland crew is dealing with an emergency. ”

The commander's majestic voice came from the communicator, and this voice could only be heard by Qin Guan: "What are you doing, haven't you finished it yet, I heard that you were called to repair the toilet?" So what the damn maintenance squad leader is going to do? Moreover, a damn toilet seat you actually repaired for half an hour. ”

Qin Guan snorted a little tired and said: "Captain, first, I really don't repair toilets, I'd rather repair more complex carriage interfaces, second, the toilets on this car are all out of service, I think next time I want to repair it again, I may have to rebuild a toilet, and also, you have overstepped the command, what can you tell the maintenance squad leader to assign me a task." ”

The commander scolded: "You don't come with me to do this, a little kid who is like an old miser at a young age, how much Lao Tzu spends at your age, don't you just want to make a little more, do you want the money, hurry up and get the engine!" ”

Qin Guan sighed helplessly and responded stylizedly.

……

In fact, Qin Guan is very tired of this kind of life, he was born with a lot less conditions than others, an orphan, and he really came to this world with a red strip, and then started from scratch. When others set off, he had to work hard to reach someone else's first, and then he had the qualifications to compare, he learned all kinds of skills, what to make money, he learned anything, and then he came to the boring interstellar train as a maintenance worker.

He walked on the platform of the rail station, where gravity was like gravity, and people were constantly boarding, but he seemed to be in a different world from everyone else.

"I heard that the Luo family was occupied by the dragon people, and the blood flowed like a river." This was a woman dressed in fancy clothes, talking to her companion, "Our line is just about to cross part of the Luo family's star field, do you think something will happen?" ”

"It's not that serious, the star field you're going to pass through is relatively remote, and the train is just passing by quickly...... But I've also heard that the warriors of the Dragonman Clan are too strong to be killed. Her companion said, "Now another family has been destroyed, and the Luo family has a territory of eight planets, right?" The family of more than 400 years has withdrawn like this, I see, the alliance will not last long, sooner or later the dragon race will hit the alliance star! ”…,

The fancy dressed woman was surprised: "Wouldn't it? I heard that the dragon general is the nemesis of the dragon people. ”

Her companion sneered: "That's propaganda, General Long did eliminate a lot of dragon people, but those few times were defeats, what's the use of being powerful alone?" The alliance has never been victorious, so many big families with solid foundations have been destroyed one by one, I will not be surprised that there will be a monster-like dragon clan in the alliance star one day, and now the alliance is also in a hurry, anyone who breaks through the level of a warrior will be rewarded, the higher the level, the higher the reward, what did you do earlier, and now I am in a hurry. ”

The two women sighed again.

Qin Guan sighed and strode into the maintenance passage of the Wasteland.

The ion engine is the pinnacle of the Human Alliance's technology, and its efficiency is amazing.

The interstellar train "Wasteland" docked at the starting orbital station of the Alliance Star 6, and four huge ion engines were installed in the front of the locomotive, and Qin Guan was driving a small maintenance car floating on the track directly into the huge engine. No one has the authority, and no one wants to face this behemoth alone, there are countless steps to temporarily self-check alone, which is also the most sophisticated thing and the most complex thing in the Human Alliance.

But Qin Guan still entered the maintenance channel alone, and it was obvious that he had obtained this permission.

Qin Guan is twenty-two years old this year, but the Wasteland is more than a hundred years old, and he has witnessed the process of human navigation in the universe, and the distance traveled is estimated to reach the center of the Tianhe system. But this is a violation of the alliance's safety regulations, no matter who is maintaining any train, as long as it reaches the deadline, it should be sent to the overhaul station for scrapping after its life, this life depends on the state of the engine, Qin Guan concealed all the data.

Capable captains like old cars, because with the depreciation of the engine, the operating space is large, if you do well enough, there is a capable talent, then the surplus carrying capacity of the train can do a lot of things, such as doing some private trade, some people say this is called smuggling......

As the largest transportation system in the universe, the interstellar train has complete functions, the huge battleship is only equivalent to one of the trains, and the Wasteland can theoretically pull 500 carriages for interstellar travel. But in that case, it is not easy to control, so the design mount is a standard column of two hundred and thirty sections, think about how majestic a starfleet with hundreds of warships is, and the Wasteland can pull it all with one locomotive.

Every corner of the train has a maintenance channel to arrive directly, and Qin Guan enters the wasteland engine to take the reserved channel, which is not complicated, and the difficulty is how to obtain permission.

The maintenance car does not have a sealed cabin, he relies on the protective armor he wears to get life support, and he can't feel gravity here, and if he pushes the maintenance car with a little more force, it will crash around inside the engine, so he must be very careful. Qin Guan constantly observed the inside of the ion engine through the transparent mask, it was so big that it was like a castle, and he was the craftsman who came in to repair the castle.

Of course, this is not a castle, but the most complex industrial masterpiece, and if the castle is broken, it can still live in people, and this is a waste if it is broken.

Qin Guan knows the interstellar train very well, he has been understanding it since he was sensible, and he has hardly done anything else, in the eyes of others, the way the interstellar train operates is the pride of the human alliance, and the average operating cost is only a few hundredths of the interstellar spacecraft, and the key point is the power system and docking system. In Qin Guan's opinion, it was the same, but he felt that this momentum did not seem to be enough to reflect the advantages of the interstellar train, and there was still a lot of potential that had not been explored.

It's just a gut feeling, and he thinks there should be a more reasonable way to operate. …,

Inside, there is a huge cavity, and the surrounding walls are lined with diamond-shaped patterns, these are the energy compression modules, and this cavity is the core part of the engine - the energy pulser.

The reactor ionizes the medium at high temperature, and then the charged medium is pushed out by this pulser.

It was not easy to create huge energy pulses, and countless energy compression modules were arranged and superimposed, finally reaching a terrifying level. The way of superposition is very particular, and the energy compression also follows a curve formula, and human scientists have come up with many superposition models, each model has a maximum peak, and then no matter how much you superimpose, it will form interference, and finally the power will not increase but decrease.

Qinguan's maintenance vehicle is connected to the maintenance post in the engine, which is the self-inspection maintenance terminal, and there are many such maintenance posts on the wasteland, and each maintenance post is a detection point. Soon, the information from the terminal entered the maintenance vehicle, showing the condition of the entire engine.

"It's not optimistic." Qin Guan shook his head and muttered to himself.

After a hundred years of operation, the power and the decline of three percent, this is still a lot of energy superposition modules, but the modules that are not broken have also aged. The adaptability of the superposition model is too narrow, and the fluctuation of the energy output of a module will affect the overall power, even if the tens of millions of modules are brand new, as long as one of the modules or one of the energy channels is aging, the whole will be seriously affected.

Qin Guan didn't have time to carry out a major overhaul, the Wasteland had to set off tomorrow, and what he had to do was to do something even more exaggerated, changing the superimposed model. The output of each energy stacking module is measured, and then the energy is stacked in another way, so that the power follows a different curve and maximizes power recovery.

In his opinion, it would be a fool's job to overhaul it at this level, and it would be almost new with a different model.

But in the eyes of others, this method is not something that people can do, it is equivalent to crooking a pillar and you rebuilding the whole building......

This requires a lot of computation and verification, and it takes hundreds of working days to rebuild a model in a computer center.

Detection, calculation, Qin Guan used many formulas at the same time, he has his own unique operation program, as long as the state data of the module is input, you can quickly select the applicable model. Of course, this program is not very accurate, so it will come up with several models to choose from, which line is specific, which one requires long-term experience, but Qin Guan is full of confidence in this dice rolling-like way.

Soon he had his eye on an alternative model, and with a tap of the pen computer on his wrist, the renovation project began.

Countless spider-like robots crawled out of the maintenance truck, their thin legs attached to the inner wall of the pulser's cavity, and rushed to their work site. Qin Guan knew that they would complete the task meticulously, but the key parts still had to come by himself, and the smoothness of the energy channel was a guarantee of safety, and he had to complete this finishing touch by himself, so he pulled out the welding torch on his body, left the maintenance car, and floated to the depths of the engine.

"Tomorrow, it should be able to start normally."

……

Each section of the interstellar train is two hundred meters long and more than fifty meters in diameter, and the locomotive is larger than that.

The door opens, this is the conductor's room at the front of the train, the conductor is a very status person, so he lives very well, the front of the train has simulated gravity, the captain's room has many rooms, living facilities are readily available, and some of the conductors even have a garden and swimming pool inside. It's hard to imagine what the space swimming pool is like, the commander's room is still a forbidden place, and you can't trespass on it as the chairman of the shipping bureau.

Qin Guan stepped in, and the first room he entered was the captain's office, and the commander was waiting for him.

Every commander was an excellent soldier when he was young, and he had made military achievements, so this treatment was not envied by ordinary people, and the commander of the Wasteland was the same as his car, he was older, and he was even older than his car. The human warriors have been stimulated by their potential, and as long as they enter the second order, they can easily have a lifespan of more than a hundred years, so the commander of the Wasteland is still strong. …,

Qin Guan was very envious, because he was one of the very few people who had not been trained as a warrior.

"You're done?" The commander touched the beard on his lips.

Obviously, Qin Guan's access to the engine compartment and here was all his authorization.

Qin Guan nodded, took out a small chip and handed it over, and said: "The superimposed model was reconstructed by me, and the data is all in it, you must input it into the driving system yourself, otherwise the power will not match, and it will be restored to about ninety percent, although the life span is a little short, but it should be no problem to finish this trip." ”

The interstellar train usually takes a year, referring to the time of the Alliance, and it passes through most of the planetary orbital stations of the Human Alliance along the way.

The commander was slightly stunned: "You changed the superposition model of power?" Is it reliable? ”

Qin Guan said calmly: "I will be responsible." ”

The commander looked at him deeply, and he wanted to ask, "Are you up to this responsibility?" But after a while, he nodded and said, "Okay, I believe you, and I can only believe you, if your maintenance squad leader notices, have you thought about how to explain it?" ”

Qin Guan said lightly: "It is impossible for him to perceive it. ”

The commander asked again: "I'm going to add five knots this time, no problem, right?" ”

They are smuggling, because the system is different, so although the maintenance squad leader does not have greater power, he can still directly sue the captain for violating the law. It is a serious violation of the law to use the surplus power for their own benefit, but if there is no ability, this law can not be violated, although the train power is depreciated every time, but this set must have strict testing procedures, each car commander will quarrel with the shipping bureau because of this, and hope that the depreciation is larger, but the shipping bureau is often darker than them.

"Five knots?" Qin Guan hesitated, "Then my remuneration will be doubled." ”

The commander only frowned slightly and agreed, "No problem, but you have to make sure of the power." ”

Qin Guan gritted his teeth and said: "If you follow the previous route, there will definitely be no problem, but I heard that there is a section of the star field controlled by the Luo family that has been invaded by the dragon human race, and if you want to bypass it, the energy may be tight, so you must strictly control the route, and the energy consumption of the new model may be a little large." ”

The commander exhaled heavily and said, "This is my business, you go ahead, do your business." ”

Qin Guan nodded and turned to leave.

The commander squinted his eyes at his background, he didn't have any bad intentions, he admired this calm young man in his heart, and those who broke the law were not necessarily bad people, but they were just selfish. In this era, even if he has such a status in the alliance, he can't resist the temptation, what is his own status, the status of the family is the eternal glory.

What is the Human Alliance? It is the alliance star plus the major families, this is called the alliance.

Is the commander of a car of high status? Look at those domineering families, that is called status, they have their own planets, they have their own star territory, and the family elders stationed in the alliance star also determine the fate of the entire human alliance, why can't they establish such a family? Hope Ze will be remembered by his children and grandchildren, and hope that someone will always remember his ancestors, vanity is a common disease of all human beings.

He looked down at the chip handed over by Qin Guan and sighed: "It's a genius, it's a pity that ......"

It's a pity that he is not a warrior, if he is not a powerful warrior these years, he basically has no chance of getting ahead, because humans have been at war with the dragon people for decades, and the situation is becoming more and more critical. Especially in recent years, the strength of the dragon race has grown rapidly, and more and more advanced warriors have appeared, making humans feel powerless.

What kind of creature is that, strong enough to fight a machine, and the machine is faulty, and they don't.

Therefore, even if human beings have stronger technology, they are still at a disadvantage, because their bodies are too fragile, and no matter how strong the tools are, someone has to use them. Therefore, the alliance decided to encourage human beings to strengthen their physical fitness, stimulate their potential, and the more powerful people are, the more respected they will be, and use this as a guide to strengthen the entire race, forming an atmosphere, and then make up for the shortcomings with scientific and technological means to counter the dragon race.

Qin Guan's life of more than 20 years has not been spent anywhere, so he is destined to have no future, so he can only bury his head in coolies.

As an orphan, he can only start from scratch, and when all the foundations are laid, and when he reaches others, he will find that his prime is gone, and he will no longer have the opportunity to obtain the desired position. What ideals, for him are extravagant expectations, others start training to stimulate their potential from an early age, but he must bury his head in learning all kinds of money-making skills, before that, he has no conditions to stimulate his potential, and he has no conditions to let go of everything to train to become a high-end armorer that everyone admires.
