Thank you Tianhai Xiangyun for your generous reward.

"Master Liu, can you tell me more about the sniper rifle you know? Although we have been in the army for so many years, we are really very unfamiliar with these guns, and sniper rifles really can't be fully automatic? Is it really possible to wreck tanks and helicopters at long distances? "There are two roads leading from the base to the outside, one is to take a jeep and take the mountain road and then enter the provincial highway S302 Wanyuan to Kaesong.

The other is a train that leads directly to the interior of the base mountain.

How did Liu Yijiu come here, he didn't know, after all, it was a jeep that entered the base at the end, and if it hadn't been for the accident, he wouldn't have been here.

And this time, it happened that the train that transported the materials from the base went out in the evening, and they took this special train to Shancheng, and then went through the Chengdu-Chongqing Railway to Rongcheng, and then took a train from Rongcheng to Kuncheng through the Chengdu-Kunming Railway......

The route is extremely complicated, more than 1,000 kilometers away, and after changing trains, you have to sit for four days.

If you drive, not to mention the long distance, the road conditions are extremely poor, even Chen Dashan is unwilling to drive for three days, the driver suffers, and the person who sits in the car suffers the same offense! Their Ninth Academy belongs to the confidential unit, and the certificate of the Fifth Machinery Department that is directly used when going out is the outside aerospace 002 base, and on the train, it is also qualified to sit in a sleeper, and it is also a soft seat!

Zheng Hao is still good in this regard, at least he has made soft seats for several people.

"Battalion Commander Chen, can you tell me what is the difference between automatic and semi-automatic as you understand it?" Despite the long distance, a few people could only pass the time by chatting or playing poker in the carriage. Chen Dashan took Su Hang, that is, Xiao Su who was with Chen Dashan that Liu Yijiu and the others met at the beginning.

In these years, the speed of the train is only 40 to 60 kilometers per hour, and it is extremely normal to be delayed.

Regarding Chen Dashan, Liu Yijiu didn't know what to say. This guy gave Liu Yijiu a feeling of not learning and not being able to do it from the beginning. Liu Yijiu designed a semi-automatic sniper rifle, and he actually said that it was called semi-automatic when he pulled the bolt with a shot.

Liu Yijiu kept wanting to ask him, but he didn't find a suitable opportunity.

"Does this make a difference? Aren't the sharpshooters in our army using old guns that have been modified from the past? Chen Dashan looked puzzled.

"Rifles are now divided into automatic, semi-automatic, non-automatic. Automatic rifles, that is, automatic ammunition feeding, press the trigger, and the magazine bullets can be exhausted at one time...... Semi-automatic, that is, the five or six semi-automatic that we use the most, automatically reloads bullets, and only one bullet can be fired every time the trigger is pulled...... It's not automatic, it's the kind of ...... you said that you pull the bolt of the gun and shoot it" Liu Yijiu's explanation made Chen Dashan blush a little.

If it weren't for the fear that the other party would be annoyed and angry, Liu Yijiu would have wanted to ask Chen Dashan how he became the battalion commander.

"Uh...... This, Comrade Xiao Liu, I won't tell you, I've always been used to using that kind ......of gun, which has a long range and great power," Chen Dashan scratched his head a little embarrassedly and smiled.

Liu Yijiu was completely speechless.

But it's also relieved to think about it, there seems to be no academic restriction when you are a soldier at this age.

"The kind of sniper rifle that uses a single shot and pulls the bolt is mainly used on some very powerful anti-materiel sniper rifles, which is what you said can destroy tanks and helicopters. The rifle can even have a maximum range of more than three kilometers, but it is too bulky to carry. Moreover, to achieve such a level, you have to use special bullets......" Liu Yijiu began to popularize the basic knowledge of anti-materiel sniper rifles to Chen Dashan, and don't make jokes when the time comes.

"Can we produce it?" Chen Dashan's eyes lit up as soon as he heard this.

Even with the soft seats, the private compartment could not isolate the clanging sound of the wheels colliding with the rails outside.

After the excitement of taking the soft seat of the train at the beginning passed, Su Hang and Qin Huaibao fell asleep deeply, and Liu Yijiu also wanted to sleep, but Chen Dashan kept pestering him to talk about the use of sniper rifles and various types.

The train to Shancheng is very fast, but from Shancheng to Rongcheng, it stopped several times along the way and sat for more than ten hours. Liu Yijiu was speechless, in the era of the intercity Harmony train, it took an hour to reach Rongcheng from this city.

The train from Rongcheng to Kuncheng, the capital of southern Yunnan, departed at seven o'clock in the evening, and when the train departed, it was already more than an hour late.

The inside of the ordinary carriage became crowded with the return of educated youths to the city, and they couldn't even step on their feet in the aisle. Thanks to the fact that the weather is now cooler, otherwise people will suffer even more. Even with the stark contrast, Qin Huaibao still felt that being on the train was a kind of sin!

"Alright, we're coming. The 298 Factory Liaison Office should be waiting for us. Chen Dashan did not feel uncomfortable staying in such a narrow space for three days, three nights and sixty hours, and said to a few people who were depressed when the train was about to enter the station.

"Leader, Kuncheng has a plane flying to Rongcheng, right? Why don't we fly back on a plane? This kind of crime is really too difficult......" Qin Huaibao couldn't help but cry excitedly when he saw the Kuncheng Railway Station getting closer and closer......

"Dream on! Let's not talk about whether we can catch the weekly flight, that is, if we can catch up, it is not certain whether we have a place or not, our level is too low! Su Hang has been on the train for the past two days, like frosted eggplants, and the two of them have been bickering all the way to pass the time, and in the end they don't even have the strength to bicker.

"Alright, shut up!" Chen Dashan was speechless.

These two people are probably natural enemies.

With the flow of people getting off the bus, several people were pushed towards the exit outside.

The dilapidated train station and the passengers in blue and gray clothes make everything in front of you give a sense of the vicissitudes of history.

"If only you had a camera, you could write it all down......" will be difficult to see in the future.

"Wow!" Seeing a beautiful girl wearing a red plaid shirt and two big braids standing outside the iron fence at the exit of the station, Qin Huaibao suddenly came to his senses, and pulled Liu Yijiu to point at the girl for him to see.

Liu Yijiu ignored him, but walked directly towards the girl.

"Master, I'm just tempted, you actually came to act! That's not right, isn't it? Seeing Liu Yijiu walking towards the girl, Qin Huaibao immediately screamed, causing the people around him to look at him in surprise.

"Shut up, don't look like a dirt bun, we are cadres, we must always pay attention to our image!" Although Chen Dashan is a battalion commander, he usually has very little time to come out. At the Rongcheng Railway Station, they got on the train as soon as they got off the train, and they had never been to the first city in the southwest at all, and naturally they didn't see many well-dressed young girls.

"Battalion commander, that girl seems to be ......from Factory 298 to pick us up," Su Hang pointed to a sign on the girl's side and whispered to Chen Dashan.

Chen Dashan was speechless......

He also thought that Liu Yijiu saw that girl was beautiful and went up to talk to him......

"Good leader, I am Wang Xinyue, the external liaison officer of the 298 factory, and I came to greet you on behalf of the 298 factory. The car is on the side, please ......" Seeing a few people behind her, the girl in the plaid dress said crisply.

"Okay, good ......" walked up to him and found that the girl did not look as stunning as she did from a distance, with an ordinary appearance, and there were many brown spots on her face.

Immediately, Qin Huaibao was disappointed.

The 298 factory was in 1936 before the Anti-Japanese War, and in 1939, the Preparatory Department of the Military Optical Equipment Factory of the Ministry of Military Affairs evolved into the 22nd factory of the Military Industry Administration of the Ministry of Military Affairs, and then evolved into the 53rd Arsenal. In 1957, it was renamed Yunguang Factory.

This is the first professional optical instrument factory in China.

With Wang Xinyue coming to greet a few people, there were two convertible 212s, from which it can also be seen that the Yunguang Factory is still very popular with the leadership.

"Leader, I'm really sorry, our director can't come to greet you in person because of something......" As soon as she got into the car, Wang Xinyue said to Liu Yijiu and Chen Dashan who were sitting in the back.

"It's nothing. Director Xu, is your factory very busy with research tasks and production tasks now? Liu Yijiu shook his head, he didn't have any opinion on who would pick them up. It doesn't matter if there is no one to pick them up, they take the bus or walk by themselves.

As long as Yunguang Factory can solve their problems.

"Busy but not busy, mainly for various meetings, the researchers and workers below have nothing to do all day long, many people come to report in the morning and then go home......" Wang Xinyue replied very casually, she didn't feel anything abnormal about such things, all these years, isn't it like this!" Leader, are you here to give them any production tasks? ”

"Don't call it a leader, we are here to ask brother units to cooperate, not to assign you any production tasks......" Liu Yijiu also replied casually.

"Ahem......" Chen Dashan heard the conversation between the two, and couldn't help but put his fist to his mouth and coughed dryly, and then said very seriously to Wang Xinyue, who was twisting his head in front of him to communicate with them: "Comrade Xiao Wang, didn't your leader tell you not to inquire about our identities at will when they arranged for you to pick us up?" Didn't you learn the rules of confidentiality when you entered the factory? ”

"I'm sorry, leader! Don't ask what you shouldn't! I'm sorry......" Hearing Chen Dashan's serious question, Wang Xinyue's face suddenly changed.

They are all classified military-industrial units!

Like most cities, the provincial capital was not very large, and the roads were narrow and potholed, but because there were not many cars, jeeps could easily reach 70 kilometers per hour.

Kuncheng is also a big city in the southwest, but compared with Rongcheng and mountain cities, there is still a lot less prosperity.

Many people's clothes on the streets have also begun to become beautiful, which has become a beautiful scenery in this city with spring all year round.
