Regarding the train speed in this era, Liu Yue is really powerless to complain.

He also knows that this is the quickest way to get around now.

In the past, when going out from the base, the car had to climb over Daba Mountain and Qinling.

In winter, the mountains and frozen roads are very dangerous and even slower.

In Liu Yue's era, the speed of high-speed rail has reached 7, 800 kilometers per hour, maglev trains and faster light rail shuttle through the city, farther away, direct plane, now such a journey, Liu Yuejue is too wasteful of time.

What used to take a few hours to reach now takes a week or more.

For defense science and technology workers, time is the most precious.

Fortunately, Liu Yue has been in this era for several years and has adapted to this intolerable inefficient travel.

It's useless to be in a hurry.

Trains don't go faster because he's in a hurry.

There were not many people in the special train from the base to the railway station in D County, except for Liu Yue and his party, other travelers were sparse and did not fill a carriage.

A few people randomly found a place to sit down.

Liu Yue's bag containing the materials was placed casually next to his seat.

Soon, the train left the base in the dark of night, a train station that didn't even have a full platform.

Du Feng, Zhang Zhen and others, who saw them off, watched the train leave and did not leave for a long time.

"Leader, do you think this can be done?"

Zhang Zhen asked Du Feng.

Du Feng shook his head, "Theoretically, it can, but who knows? This time is not short, and the troops have to ...... in a hurry."

He thought that Zhang Zhen was asking whether Liu Yue's two newly designed weapons could be solved.

Zhang Zhen couldn't ask again, "Could it be a new charge?" The previous charge was scrapped with tens of millions of shells...... This new one didn't last long......"

"It's useless for us to talk here, everything has to be told by facts. The troops need to be in a hurry, and if they do not solve the problem, they will produce, which is a waste of national assets. You can't produce it and waste ......," Du Feng sighed.

They are not professionals and simply don't know what the problem is.

Even Liu Yue, a designer, doesn't know what the problem is.

Newly designed weapons do not conform to the development process in the first place, there are not many tests, and it is normal for problems to occur.

I'm afraid that something will go wrong in the future.

After Liu Yue got on the train, he continued to ponder what went wrong with the two rockets.

He went through the whole design from his mind over and over again, and even analyzed the possible defects in the whole production process, and carefully re-analyzed all the technical documents and production materials, and also discussed them with the people in the technical department.

From their design data, production process documents, and the data on the quality tracking card of the production process, there is no problem.

Even Liu Yue checked the places where he might have caused negligence.

Still confident that there is no problem with the design.

Ye Xin sat aside, looking at Liu Yue from time to time, her expression kept changing, and sometimes she even gritted her teeth, not knowing what she was thinking.

As the only passage out of Sichuan in the northeast of Sichuan, cadres in the entire northeast of Sichuan need to travel by train here on business trips and people who go to other places to make a living.

The train station in County D, which has just been built for a short time, is small but crowded.

Yan Heping, Liu Baojun and several other security personnel protected Liu Yue and Ye Xin in the middle, waiting for Lu Qiang, who went to buy tickets.

On the train platform, it was very chaotic.

There are people waiting for the train with large bags and small bags around, and the information in Liu Yue's hands cannot be lost.

Especially after the train arrived, the crowd was even more crowded, Rao is few people protected Liu Yue and Ye Xin, and several people were also squeezed around.

Carrying large bags and small bags, crowded towards the narrow car doors, many people threw their luggage in through the open windows and drilled directly through the windows.

Liu Yue was speechless.

Finally, a few people squeezed into the carriage they were in in the crowded crowd, and Yan Heping and the others were already sweating.

Especially Yan Heping, two buttons of the military coat on his body were squeezed off, and his armpits were also cracked......

With the protection of Yan and Pingping, Liu Yue and Ye Xin did not suffer much crowding.

After getting on the bus, Liu Yue found that the entrance of the carriage they were in was crowded, but there were not many people inside.

"The entire railway was built because of the existence of our base, and this carriage is specially prepared for all the third-line military industrial units in the vicinity, otherwise we would not be able to squeeze in at all...... In a few days, there will be a few more people during the New Year's holiday, and there will be more people in the province, and the congestion here may be more serious than other carriages......"

Perhaps seeing Liu Yue's doubts, Yan Heping explained to him.

There are still some privileges to be a national defense science and technology worker.

Liu Yue really didn't expect that in this era, the military industrial system was so special.

The train actually reserved a carriage.

"There are many third-tier enterprises on our side, and there are a lot of business trips in each unit. Train tickets are not easy to buy, and even if you can get a ticket, you may not be able to get on the train......"

Seeing that Liu Yue was still squeezing into the overcrowded carriage outside, Yan Heping continued to explain.

Although the carriage is relatively empty, it is only relative.

It was still full, and there were no empty seats.

There were only a small number of people in the aisle, and people in the other carriages tried to squeeze in, but they were all blocked by the conductor at the door......

The seats that Liu Yue and Ye Xin were assigned to were just two seats that were connected together.

Liu Yue didn't want to sit with Ye Xin, and Ye Xin didn't want to see her either.

Yan Heping, Xie Jun and several other security personnel surrounded them, leaving only two positions that were connected together.

Even if Ye Xin was not happy, she was the only lesbian in the entire team, and the others had to protect them, so they could only choose to sit by the window.

From County D to Hojing, it takes more than 20 hours.

This way over the Qinling Mountains, the speed of the train is not high.

Thinking about the problems of the project in his heart, Liu Yue didn't pay attention to Ye Xin, who pouted angrily with his head pinned to the side.

He repeatedly scrutinized the project he designed by himself, all the drawings were drawn by him, and a lot of theoretical verification was carried out, and at the same time he stared at production, all kinds of data were almost imprinted in Liu Yue's mind, no matter how he compared, he still couldn't find the problem.

I don't know how long time has passed, but Liu Yue still can't think of what the problem is, which makes him feel a little irritable.

A small project has such a problem, so many designs, how to come up with it?

What's more, if the problem cannot be solved as soon as possible, there is no telling when these pieces of equipment will be put to combat testing.

It won't be long before the Iran-Iraq war breaks out.

If you want to export equipment to the Iran-Iraq battlefield, you must first sell it to the Pakistanis.

The Pakistanis bought weapons at the expense of the Americans to support the Afghan guerrillas against the Soviet army.

The 80-mm anti-tank rocket launcher is going for the heavy armor of the T-72, and it is impossible for the country to get this tank as a target for testing.

"Are you worried about the problems of the two projects?" Ye Xin's voice was very soft.

She originally decided not to talk to Liu Yue.

But the shaking and clanging sound of the train, coupled with the dark shadow outside the window, made her unable to sleep at all, and she couldn't hold it back.

Liu Yue didn't react.

Seeing that he ignored him, Ye Xin angrily stabbed Liu Yue's arm with his fingers.

"Am I so terrible?"

Liu Yue looked at Ye Xin awkwardly, not understanding how she had changed her temperament.

Ye Xinyin bit her lower lip with silver teeth, and it took a while to muster up her courage, "Three years ago, when you were in class at the Polytechnic Institute, you knocked down a girl and didn't apologize, remember?"

The tone was full of resentment.

Liu Yue's eyes widened suddenly!

"It's you?!"

Liu Yue looked at Ye Xin incredulously.

He remembered it, and he didn't even pay attention to the girl's appearance at the time, but he remembered the feeling......

At the Capital University of Technology, Liu Yue went to take ammunition classes to make up for some of his previous knowledge deficiencies.

In his time, all kinds of weapons had been developed for several generations, and without a foundation, those high-energy chemistry-related things could not be taken out.

When he was in class, Liu Yue rarely communicated with others, listened to the lecture silently, and the professor did not drive him away.

One day, Liu Yue couldn't help but refute the professor's arguments, and argued-for-tat with the professor who taught ammunition science in class, which finally made the professor lose his mind to class.

Liu Yue questioned the results of the professor's research for a long time!

And some theories only emerged decades later......

In the end, he was attacked by his classmates majoring in ammunition science, and he had to flee.

As he escaped, he stepped on the feet of a petite, emaciated girl, and knocked the girl down......

Then, the girl is below, and he is on top......
