A professor's rebirth: I entered Tsinghua University in 1977.

As soon as the commendation meeting ended, Liu Hongyi asked Duan Weimin for leave.

He wants to go back to Chuzhou.

Duan Weimin was a little surprised: "It's still some time before the Spring Festival, why are you in such a hurry to go back?"

You are now a serious cadre of the research institute and a senior technician at the company level.

You have to abide by the work rules of our research institute, do you understand?

Staff Officer Liu!

Tan Dexi hasn't returned to Factory 576 yet.

Project 130 has not been completed yet.

Tan Dexi is a man of particularities. He cannot abandon Duan Weimin and Project 130 halfway just because he has resumed his position and benefits.

Liu Hongyi smiled and said, "Director, I'm not going back to celebrate the New Year. I'm going to look for someone..."

"Who are you looking for?"

"Chen Jiayou, Professor Chen, have you heard of him?"

"Chen Jiayou, I've heard of him. He's from Jingjiang University. What do you want to see him for?"

"Optical sights, night vision goggles."

Liu Hongyi said concisely.

"Director, I want to further improve the QLZ77's shooting accuracy and night combat capabilities."

The 35mm automatic grenade launcher developed by Liu Hongyi passed inspection and was officially named the QLZ77 automatic grenade launcher by the Commission of Science, Technology and Industry for National Defense. Q stands for light weapon, L for grenade, Z for automatic weapon, and 77 for model.

In Liu Hongyi's memory, the automatic grenade launcher later launched several improved models.

Among them is a high-precision sniper grenade.

Equipped with an optical sight, automatic ballistic calculator, rangefinder, infrared night vision device, it has high shooting accuracy and can be used as a sniper gun. It can also operate in all weather and all terrains.

With current technology, it is difficult to develop an automatic ballistic calculator.

But you should be able to try high-precision optical sights, infrared night vision devices, and rangefinders.

Professor Chen Jiayou is a leader in this industry.

"Night fight?"

Duan Weimin was surprised at the young man's forward thinking.

"Yes, Director."

"If war breaks out on the southern front, we must be prepared for night battles. Furthermore, the Anlang Nation has built a large number of permanent and semi-permanent fortifications in the mountainous and forested areas along the border. Currently, we only have two types of individual weapons capable of neutralizing these firing points: the 40mm rifle and the 82mm ammunition. However, both the 40mm rifle and the 82mm ammunition have a weakness that is difficult to overcome..."

"What weakness?"

Duan Weimin asked immediately.

"The shells are too heavy."

"The 40mm rocket weighs 2.1kg, and the 82mm armor-piercing round weighs 6kg. Compared to the 35mm howitzer, it's much heavier. The soldiers are carrying too much weight, and a forced march over complex terrain would be exhausting."

"Another point is that the direct firing range of the 40mm and 82mm rifles is too short. The maximum direct firing range of the 40mm rifle is 300 meters, and the 82mm rifle is less than 400 meters. Shoulder-fired, the target is too large and easily becomes the target of concentrated fire from the enemy."

"The Anlang people have fought for decades, and their marksmanship is generally very good."

"If we can improve the accuracy of the .35mm howitzer, and use its concealment capabilities to fire from 35 meters away, it will be difficult for ordinary enemy riflemen, unless they are snipers. But it will still be harder to detect than the .40mm and .82mm rifles."

The 40mm and 82mm rifles are smoothbore guns with low accuracy. If you want to hit the target accurately, you can only shoot at close range.

In this regard, the rifled 35mm howitzer has obvious advantages.

Duan Weimin couldn't help but nod repeatedly, and he admired his ideas very much.

"If you can develop these things you mentioned, then the 35mm howitzer will be even more powerful... No, not only the 35mm howitzer, but also the 40mm, 82mm, and even rifles can be equipped with night vision scopes..."

Duan Weimin said excitedly.

Liu Hongyi couldn't help but laugh.

Director Duan is still too optimistic.

Even if high-precision equipment such as optical sights and night vision sights can be produced at this stage, they are relatively expensive and can only be equipped on high-value weapons. It is too luxurious to install them on rifles.

With our current national strength, we simply cannot afford it.

Even Liu Hongyi was not sure that he could make this thing.

But gotta give it a try.

"By the way, isn't Chen Jiayou a professor at Jingjiang University? Jingjiang University is in Daning. Why did you return to Chuzhou?"

Liu Hongyi said with a wry smile, "Director, Professor Chen has been out of Jingjiang University for a long time, and I don't know where he is now. I'm going to Chuzhou to find his wife, Teacher Shen. Teacher Shen is a master embroidery artist and is currently working in a small factory in Chuzhou. I'll ask her; she should know Professor Chen's whereabouts."

Duan Weimin couldn't help but shook his head.

These days...

It’s really hard to find someone.

Duan Weimin was not very clear about the exact whereabouts of the pillars of their three institutes, so he could only ask people around to find out.

"Okay, how many days do you need? This isn't considered leave, it's considered business trip."

Liu Hongyi wasn't going home to play, so it wasn't appropriate to treat him as taking a personal leave.

"Five days for now. If Professor Chen is out of town, I'll call you to report."

Liu Hongyi is a very planning person.

Duan Weimin nodded and then, with concern, reminded him, "Remember to go to the office to get a letter of introduction. Also, if you're traveling alone, remember not to wear a military uniform. Some young people these days just like military uniforms."

Duan Weimin was worried that Liu Hongyi would be robbed.

This kind of thing happens often.

A grass-green regular military uniform is the "ultimate dream" of many social hooligans.

Liu Hongyi is young after all, and Duan Weimin is worried that he might get into an accident.

"Yes, thank you, Director. I will be careful."

Liu Hongyi hurriedly expressed his gratitude.

After leaving Duan Weimin's office, Liu Hongyi went to Yuan Gang to get a letter of introduction, stamped it with the official seal, carefully folded it, and put it in his pocket. Yuan Gang now had a very good impression of him and was willing to meet his every request.

After saying hello to Tan Dexi, he returned to his dormitory, changed into casual clothes, packed some simple luggage, left the research institute with his backpack, and took the bus to the bus station.

In the evening, Liu Hongyi returned to Chuxin County.

It was getting late, and there was no way to get to Yangou Farm in time; there were no cars available.

Go directly to the district compound to find Ai Gaofeng.

Ai Gaofeng still lives in the original room, on the second floor of the tube-shaped building, which is a house with three connected rooms.

One of them is the living room, and the other two are Ai Gaofeng and Ai Xiaoyu's bedrooms.

Knock on the door.

After a moment, a timid girl's voice was heard.

"Which one?"

It’s Ai Xiaoyu.

Ai Gaofeng implemented the policy and served as the second secretary of the prefectural party committee. Ai Xiaoyu naturally left Yanggou Farm and returned to the regional compound.

But she is still very timid. After Ai Gaofeng goes out to work, she basically locks herself in the house and does not go out unless there is something important.

"Xiaoyu, it's me, Liu Hongyi."

Liu Hongyi said loudly.

With a "creak", the door opened, revealing Ai Xiaoyu's surprised little face.
