As all human beings know, the history of the Human Alliance is only 1,500 years.

At the same time, all human beings know that the history of mankind is certainly more than 1,500 years.

All memories began with the giant car, from which the ancestors of the Human Alliance came out 1,500 years ago, but their minds were as blank as if they had been washed, and they began to live and multiply in the Alliance. Until fifteen hundred years later, humanity has not been able to crack the core of this huge front of the car, firstly because of heavy protection, and secondly, for fear of triggering the self-destruct device, which is now stored in the Alliance Military Academy.

The Alliance Star Revolution has rotated countless times, many people have forgotten about this place, this place has been opened up as a research area, but it is impossible for human beings to make further breakthroughs in the research of this locomotive, even researchers pay little attention.

Humans don't know how this unimaginably large locomotive brought their ancestors to this planet, but they have obtained some peripheral scientific and technological information, so that humans have been able to conquer this star field with interstellar trains for thousands of years. A few decades ago, a new race emerged in this star field, the dragon race, whose powerful combat power has caused the human race to continue to lose, and several large families have completely lost their planets and retreated to the Alliance Star.

They were even more desperate to crack the front of the car, to find out if they were holding on to hope.

They called this locomotive the Relic Train.

……

Qin Guan needed money very much, and he needed it very much, so he agreed to help the commander with this favor.

What is most needed in this era is the armor, the armor that can fight against the dragons, the stronger you are, the higher your status, this is the unanimous ideal of everyone. It's a pity that Qin Guan has been an orphan since he was a child, that is to say, there is no one for him to train to become a soldier, which requires a lot of money, Qin Guan does not have it, and he also has no time, because his time must be used to make money.

So he changed his ideals and was determined to build a great family starting from himself, so he would work hard to make money, so he would do this kind of work of wasting his life in space at a young age. It doesn't matter, the benefits of this job are very high, money is the foundation of the family, of course, there must be a woman, he has been prepared for this, his girlfriend and he grew up together in an orphanage.

Out of the Alliance system, the Wasteland entered the empty universe, and the days passed day by day according to the time of the Alliance Star.

This broken car is amazing, Qin Guan has worked here for three years, he is the least senior person in the entire maintenance class, and anyone who has worked experience understands what this means. Basically, he has dealt with all the faults that some people have seen, and others may not have had as many problems as he encountered in one trip after 30 years, but only on such a train can he have more opportunities.

After checking around in the responsibility section, Qin Guan returned to his lounge, and the rest rooms of the crew team were all located in the front of the car, because there was simulated gravity here, and the maintenance post of the cargo compartment was not suitable for long-term life at all.

When resting, many maintenance workers will carry out potential training, everyone has lofty ideals, and the common practice method uses instruments to send out energy pulses and walk in the meridians of the human body, so as to achieve the purpose of strengthening the body. This is another great progress for humanity, the energy travels throughout the body, significantly improving the quality and longevity of the entire human race, so that they can narrow the physical gap with their opponents, the dragon race.

This kind of thing called pulse cultivation instrument is very expensive, there is only one in the average family, and if you buy it again, you may go bankrupt, and the effect of this thing is very slow, and some people have not practiced more advanced after using it for a lifetime. Of course, there are more expensive ones, which are drugs that stimulate potential, and this precious drug is very difficult to refine, and only the rich can afford to use things, and the conditions for use are also very harsh, and it is necessary to conduct a strict physical examination before use, and after a few years of observation, it can be used in the company of experts. …,

Cultivation instruments and drugs are things that stimulate potential, and if you want to improve your strength, you have to cooperate with training. If there is no appearance of the dragon race, maybe human beings will not be so demanding on their physical conditions, the key is that the dragon people are too strong, their bodies have reached the extreme of life, and they are naturally strong.

But no matter what kind of cultivation method it is, Qin Guan has no conditions.

In the lounge, Qin Guan turned on the holographic display, which showed an image of a galaxy, and he had recently been studying the movement of celestial bodies, which was his pastime. If a human has a foundation, it only takes two years to master the skills in a scientific and technological field, and Qin Guan has now been involved in many scientific and technological fields, almost all of which are at the research level, and it is expected that the cost of making money is very low, and it can basically be ignored compared to cultivation.

In his opinion, the inability to compete with the dragon race is not that the human body is not strong enough, but that the scientific and technological civilization is not advanced enough, far from reaching an extreme, otherwise technology can completely compete with the dragon race, and even change the entire universe.

I don't know when Lu Dao started, he felt that the operation mode of the interstellar train was too simple and primitive, and there was still huge room for improvement.

He reached out and touched the three-dimensional holographic image, simulating a simple star system, with a dozen orbs of light running according to a calculated program. See, those planets don't even have power, but they can move eternally, repeating themselves in calculable orbits for thousands of years under the influence of gravity......

That's right, track, Qin Guan felt that he had caught something.

Can't the interstellar train run like this?

In this way, the cost of operation can be reduced to a lower level, and the interstellar communication will be smoother and the distance can be reached farther. The current interstellar train model is too primitive, that is, a large number of interstellar ships are connected, and then the locomotive drives the slow acceleration, without the help of the orbit, and still wastes a lot of energy.

With this idea, Qin Guan set out to create several planets on the display screen, and he made these planets connect, one after the other, like a long string of pearls. As a result, the orbit underwent a complex shift, and the galaxy began to mess up, and then slowly reorganized, but it failed to complete the reorganization.

The calculations are more complicated, and the original program did not account for these accidents.

Qin Guan found that this had to solve two difficult problems, one is a huge amount of calculation, almost every object in space will affect the orbit of this string of "pearls", and the other is that the operation of the interstellar train is far from this simple, it must cross from one star system to another, the star system is changing, the orbit is also changing, the entire large galaxy is changing, and there is probably no accurate data to calculate the fixed orbit of the train.

Suddenly, the 3D display flashed, and the image disappeared.

"This broken car!" Qin Guan muttered in annoyance.

This is a problem of unstable energy supply, and all parts of the Wasteland have been severely aged, including the energy channel lines.

He was about to rebuild the model for simulation, when suddenly the communicator rang, and it was the commander's call. The commander must have called him something big, if it is a general problem, you can call the maintenance squad leader directly, this is a leapfrog, and it is easy to attract suspicious eyes.

"Captain, what's wrong?" Qin Guan connected this connection.

"Come to my office and don't get anyone else's attention." The captain's voice was urgent.

There must be something wrong, the video communication must be agreed by both parties, and the commander only came over with a voice, but Qin Guan could guess how anxious the commander was, because this commander was an experienced old armor soldier, and he was really on the battlefield, and he was in a hurry, and ordinary people would definitely have to jump up.

Qin Guan immediately turned off the computer, walked out of his room, and walked towards the commander's room. …,

As soon as he entered the door, he saw the captain pacing anxiously, his brows furrowed.

Seeing Qin Guan coming in, the commander immediately said: "The space we reserved is too small, now there is an accident, the front navigation class requires a detour, the energy of my old car is simply not enough to last to the next station, this is over, the engine mode you changed is too energy-consuming!" ”

"Why do you need to change the route?" Qin Guan didn't understand, this was a major event, the people in the navigation class had this power, but there must be force majeure and there was really no way to exercise the power, and it had to be unanimously approved by all the team leaders.

"Come and see."

The commander turned on the three-dimensional display, which showed a small star system, one star and six planets. This small galaxy Qin Guan Zhilu Dao, there is no station here, the reason why I want to pass by here is because this is used as a marker, it is a navigation marker, and if you can't find this galaxy, it means that it is out of course, and this star also has a very apt name: Lighthouse No. 1.

"Look, a large number of asteroids suddenly appeared in the orbit of Lighthouse One, these huge debris are moving along a strange orbit, which has blocked the route of the Wasteland, in order to ensure safe passage, it can only be circumvented, go around in a large circle, this is the new route calculated by the navigation class......"

The commander explained the problem, this circle is indeed large enough, but in order to ensure safety, it can't get too close, who knows if the orbit of this emerging asteroid belt is stable? The wasteland is such a huge column, to change the running line is to pay a huge energy consumption, this is common sense, if you don't need to change the line, you only need a little bit of maintenance power, keep pushing slowly, if you keep changing the attitude, the energy consumption will be unimaginably huge.

Qin Guan didn't answer immediately, he looked at Lighthouse No. 1 and began to think.

The situation was even more troublesome than he had expected, he had thought that there would be all kinds of problems with the Wasteland, who knew that there were also problems with the route of the Wasteland, and now his premonition was getting worse and worse, maybe all kinds of internal and external problems would erupt in a concentrated manner, and no one would be able to save them at that time. He regretted doing such a shady thing, but now that he had done it, he had to work hard to eliminate the negative influence.

"Is there a way to do it? The new route plan will be approved at a meeting soon. The commander was very anxious, this is related to his lifelong reputation, and he can't be found out, "Can you change the engine again and use an energy-saving model?" ”

Isn't this a joke, the limit of the engine is there, if you want enough power, you have to sacrifice something else, if you want to save, you don't have enough power, and then you won't have enough power to drive the train around. The commander saw that Qin Guan had this ability, so he thought about modifying the power superposition model simply, this is the pinnacle technology of the Human Alliance, and he didn't dare to say that it could be changed in the most authoritative organization.

Qin Guan was not affected by the commander's emotions, and his expression was almost numb.

When the commander was about to lose patience, Qin Guan spoke: "It's impossible to modify the engine again, this is aging power after all, it can't be like a new one, there will be gains and losses, don't be too anxious, my car master, you really can't make an accident, throw away the five carriages, and then let the power be damaged, wait for rescue, I can make them can't find out anything, no one will know about this matter." ”

The old captain patted his head and said, "There is no way to do it, I have spent money on these five carriages." ”

Qin Guan nodded and said, "When the matter can't be solved, maybe it can be ...... Do you have detailed data from the navigation class, including the asteroid belt orbit and the entire galaxy of Lighthouse One? ”

"What do you want this for in the navigation class?" The old commander was puzzled. …,

Qin Guan said: "A detour will not necessarily consume more energy, you see." ”

As he spoke, his fingers drew a line on the three-dimensional image, which frightened the old commander.

"Are you kidding, it's much farther than the route given by the navigation class!"

……

The navigation squad leader is a young and beautiful girl, only in her twenties, and it is generally impossible to be a navigation squad leader at such a young age, but the case of the Wasteland is an exception. She is a descendant of the Situ family, called Situ Ying, this family once owned the territory of more than a dozen planets, but it was the first family to be invaded by the dragon race, more than ten years ago, the family headquarters had all retreated to the Alliance Star, and the population was evacuated everywhere, Situ Ying was still very young at that time.

Situ Ying was too anxious, he even called many times, but the commander didn't come over for a meeting, and now the time is very tight, and he must come up with a decision to avoid it, otherwise the wasteland will definitely crash headlong into the orbit of the asteroid, and it will be faced with dense space of rubble.

The navigator personally came to urge, and the commander could only follow her, but Situ Ying didn't understand why the commander was so abrasive.

"Commander, what did you do with that young man in your office just now, and you left him in alone?"

said that it was an office, but in fact it was the captain's private place, how could it be possible for people to stay there alone.

"Oh, you said that man......" the commander looked a little unnatural, "he's a maintenance worker, I feel that the air conditioner is broken, let him take a look." ”

The main conference room was full of team leaders from various departments, and everyone was waiting for the team leader to discuss.

The commander looked at the crowd, raised his hand and said, "I'll take a look at the data first, everyone can discuss it freely first, and whoever has any different plans or opinions can prepare it first." ”

Everyone is a little puzzled, what opinions can they have, the navigation class has already calculated, this is not their specialty, no one will calculate, even if the data is given, it will take a long time to calculate. This discussion seems to be very fair, but in fact, it is no different from delaying time, do you have the ability to say that the navigation class is not right?

"Don't be stunned, this is a matter for everyone, so you all have the right to have a say." The commander calmly passed the data to Qin Guan, and then said, "I will also let my assistant team take a look, so I can also have an understanding of the situation." ”

Situ Ying was unhappy: "Commander, are you doubting the ability of our navigation class?" As a navigator leader, although I have not experienced a long time, I have never made a mistake, and now there is not enough time, even if I ask the navigation team to recalculate the data, it will be too late. ”

I don't know if the road Qinguan will not have time, the captain wiped his sweat, and said with a smile: "How come, I don't doubt your ability, I just want to have a general understanding of the situation encountered, if you don't even know the situation and make a decision, then my captain is very derelict in his duty, and the results will come out soon, but before that, I have doubts, because it takes a lot of fuel to divert it, and what if you consume too much, what if you encounter an unexpected situation?" ”

"Captain, this is an accident!"

"So, we have to roughly judge the extent of the crisis, and it shouldn't be difficult."

……

There was an argument at the meeting, and Qin Guan was intently calculating the orbits of all the celestial bodies in the vicinity.

Speaking of calculation methods, he has a set of unique means, and he has created a series of calculation formulas by himself, of course, this is not actually a formula, because he is the only one who uses it, and only he can use it, that's what it means.

His "formula" is incomplete, so it will not be accurate for others to use it, only he will use it.

In the commander's office, Qin Guan built a model of the star system and simulated the possible routes, which can only be roughly simulated, and it is impossible to be consistent with reality. But Qin Guan doesn't need very specific simulation results, he only needs the key data in it, and it is good to be able to find one of the simulations at a time, but none of them are accurate in the eyes of others, of course, most of them are actually meaningless. …,

The calculation took an hour to complete, and this "completion" of Qin Guan did not refer to a specific result, but narrowed down the range of possibilities. In the vast universe, he drew several routes, and knew that one of them was definitely correct, which one should he take? It's impossible to try them one by one, you can only simulate them.

After the simulation, it has to be calculated, the computer computing function on the train is not powerful, and the simulation cannot achieve real results, so it has to be calculated to understand which road does not work, which road can go, which road is optimal, and the elimination method is often the most efficient at a specific time.

The meeting over there had been going on for three hours, and the commander had been cornered no matter how much he, and he had no more words to argue, and he had already prepared for the worst, that is, to use means to destroy the traces of his own hands and feet, so that the alliance would suffer losses, and his hard work would be in vain.

Suddenly, the transmitter lit up, and the commander hurriedly turned it on as if he had seen a savior.

"Guys, I think we have a better way to build a new route that not only doesn't cost more fuel, but also saves a lot." After reading the message, the commander stood up excitedly, "I show the plan, the calculation has been done, and it only needs to be verified to execute." ”

In the center of the room, there is a three-dimensional display, and a huge star map is displayed in front of everyone, and the red line marks the new route.

"How is it possible that this lap is bigger than the navigation class's plan, and it can save more fuel?" Someone shouted.

The people here have been traveling in the stars for a long time, and they know what it means to them to go around the long way, and the one marked is the arc, which is obviously much longer than the route of the navigation class to avoid the orbit of the asteroid, and the arc means constantly changing direction, and going around the orbit of the star in a big circle, I'm afraid you will have to run out of fuel, right?

Situ Ying was silent at this time, she squinted at the line and ordered: "Navigation class, check it immediately!" ”

Although the route is too long, it feels like it is not impossible, because the interstellar not only has its own power, but also the huge gravitational pull of the planet, and if the speed and route are chosen correctly, it can definitely save fuel. The problem is that the conditions on the Wasteland are not good, such a huge operation cannot be carried out at all, and the data collection is incomplete and the time is short, can anyone really do it?

"Report Navigator!" A female navigator in the navigation class stood up, "After our temporary calculations, the feasibility is more than 90 percent, and it is completely feasible with the current data, but I am worried that there will be any accidents in the process, because the required speed is too fast, the front section accelerates, and the middle and rear sections rely on inertia and the gravitational pull of the planet to pass through the entire star system, and the fuel can be saved by 50 percent, just ......"

Situ Ying asked, "Just what?" ”

The female navigator said: "It's just that these calculation steps are really incredible, are they prepared in advance?" ”

Situ Ying also thought so, no one can make such a calculation in a short time, not to mention that there are no conditions for calculation on the Wasteland, could it be that the commander has prepared a lot of plans, this is just one of them? She said to the commander: "There is a risk in crossing the Lighthouse One galaxy at such a speed, but you can release an early warning probe in advance in case of accidents, Commander, I think this plan can be implemented." ”

"In this way, we can make a decision, prepare in all aspects, and implement the plan." The commander wiped his sweat weakly, "Could the air conditioner here also break down?" ”
