The discussion lasted until about three o'clock in the morning, and the whole technical seminar ended.

Liu Yijiu and these people are used to staying up in the base, the people of the 754 factory have not encountered such a situation for many years, and it is relatively late at ten o'clock in the evening and eleven o'clock, and they are all like eggplants beaten by frost, and it is early in the morning after twelve o'clock.

There is no special guest house in the 754 factory, after all, the scale of the whole factory is not very large, and there are many factories in this area, and there are guest houses of various competent units nearby, so he does not have to bother to solve the accommodation problem of Yu Jianguo and a few people.

When I returned to the guest house, I slept for three hours and woke up with very serious bags under my eyes, my eyes were bloodshot, and I had to prepare for negotiations with the Americans today.

"You can sleep a little longer, lack of sleep, but a woman's biggest natural enemy, easy to age quickly." Liu Yijiu couldn't help but feel a little heartache when he saw Li Rui get up with him, Li Rui followed him, always paying attention to his identity, and she had been insisting on the technical seminar like last night.

There is no problem with them getting used to them, how much of a crime it is for Li Rui, he can understand.

"That person was arrested yesterday, if his family knew that you live here......" Li Rui was very worried.

Lack of sleep, the whole person is uncomfortable, and the head is also groggy.

Her duty is to protect Liu Yijiu, and being Liu Yijiu's wife is only incidental.

Liu Yijiu pursed his lips and said to Li Rui: "Don't worry, if there is no thing, I won't go out, that kind of person." There is simply no need to bother with it. If you want to manage the entire huge industrial cluster well, you can't help offending people. I exercise for a while. Prepare for the evening negotiations with the Americans. ”

Liu Yijiu pressed Li Rui on the bed and covered her with a quilt before leaving.

He didn't see the two lines of crystal tears flowing from the corners of Li Rui's eyes.

For family troubles. Liu Yijiu didn't care, the Rongcheng Public Security Bureau should be very concerned about these things after the last time something like that happened in the Red Star Electric Appliance Factory. Sometimes, you have to be cold-blooded and indulge some people, which is irresponsible for the entire base.

It was still morning exercise, and when it was past eight o'clock, before he went to breakfast, he found that Zhou Xin and the others were waiting for him in the courtyard of the guest house without knowing when.

"Director Liu. I'm really sorry, I've bothered you so early......" Chen Rong originally had a very good opinion about Liu Yijiu, and after learning a lot from Qiu Yue's mouth, and the technologies of artillery sighting radar and cloud burst bombs were inseparable from Liu Yijiu, her impression of Liu Yijiu had a very big change.

Although it is strange why this young man can understand so many skills, it is certain that they are better than them anyway.

"Did you negotiate with the foreigner last night?" Liu Yijiu was not too surprised when he saw these people.

Whether it's the British or the French, their industrial base is really very good. Moreover, it is also one of the few industrial powers in the world, but in some fields, the whole world has not made breakthroughs, and they naturally do not have too good technology.

Americans can't work backwards on their production processes.

"Nope. They hope to be able to negotiate with you in person today. Zhou Xin shook his head, they also went to bed very late last night.

"It's your responsibility. If technical support is needed, there is no problem. But no one on our side has a lot of experience in negotiating this. And. The Americans still have to come here tonight. I have to prepare for negotiations with them. Liu Yijiu said lightly.

He could no longer meddle in negotiations with England and France.

When the time comes, the bigwigs above won't say anything. It's definitely not going to be comfortable in my heart.

He couldn't reach every nook and cranny of his hand, which he had to avoid as a young man.

Seeing that Liu Yijiu refused without even asking what was going on, Chen Rong was eager to speak, but was stopped by Zhou Xin, while Xie Lingyun on the side spoke, "Director Liu, this negotiation is related to some large-scale projects of the country, and we need to introduce more than just these things in the original negotiation." Now that you have developed a tank gun, and at the same time you have developed a gun-aiming radar that is no worse than that of the Swiss, they in turn want to introduce some technologies from us, and only you who have developed them know the value of these technologies. ”

"I've already told you the reserve price or something. As for the detailed technical situation, you can ask Chief Engineer Huang Qingyu and Chief Engineer Yu Yang, who are studying this, to cooperate with you. Although the Americans and the three European countries are in the same camp, it is not a good thing for them to collide together. Liu Yijiu didn't want to negotiate anything with the other party.

Their technology, the state wants to exchange with Europe for some technology or equipment urgently needed for other projects, this matter has little to do with Liu Yijiu, as long as they give them the corresponding value of money.

Anyway, these technologies are developed for the whole country.

When Zhou Xin told them this, several people immediately understood what Liu Yijiu was worried about.

Not long after the great turmoil ended, few people in ordinary units were willing to have too close a relationship with the Ninth Academy. I'm afraid of being implicated in the future.

After sending Zhou Xin and the others away, Liu Yijiu once again sorted out an analysis of the negotiations between himself and the Americans.

What the Americans want is still him, or rather, the Americans may have learned about the existence of Project 619 from some channels.

After all, Liu Suzhi is not very famous in the public eye of the United States, but he is an acquaintance in the eyes of the United States government and the military. When he returned from the United States with a large group of Chinese scientists, it was strange that Americans could not be impressed.

In the late autumn of Rongcheng, it was not too cold, and the warm sunshine made people drowsy, and Liu Yijiu finally paced in the courtyard to analyze these situations.

When it was almost noon, Yu Yang, who was in the artillery field, came back to Rongcheng and told Liu Yijiu that the entire artillery test could no longer be carried out. In the case of continuous fire, the barrel heats up very quickly, and these are not problems, after cooling, they tested, and the deformation of the barrel is not too large.

Moreover, a tank has only 34 rounds of ammunition in reserve, that is, at most 34 shells at a time, and then it has to rest.

In order to verify the service life of the barrel as soon as possible, to test the structural strength and service life of the tank gun, they did not care about this much, fired the gun continuously for an hour, and then rested for ten minutes, and the temperature had not yet dropped, and continued to shoot.

In one day, one gun barrel was already scrapped, and at the same time, two sets of gear chainrings needed for turret rotation were scrapped.

It didn't take long for the second one to be replaced, and the turret collapsed because it could not withstand the recoil.

It was reinforced concrete.

In the face of such a situation, Yu Yang wanted to add the artillery stabilization system, and the people at the artillery field test site couldn't call the shots about this matter, and they themselves felt that it was easy to leak secrets, so they had no choice but to run to the guest house to find Liu Yijiu.

"There is really no way, so I will add the hydraulic gun stabilization system, and now I will not let the British and the French come here again." Liu Yijiu directly proposed a solution. The turret can't withstand it, because there is no gun stabilization system, which has a great impact on the comprehensive function test of the entire turret.

According to their design, the hydraulics inside the gun stabilization system will unload most of the recoil, and the gear chainrings required to turn the turret can be replaced at the same time as the barrel. Even to the scrapping of the entire tank.

Only more than 1,000 shells were fired, and two pairs were scrapped.

"Is that okay? They're not going to visit the battery range anymore, are they? Also, there are still British people left in the battery range. Yu Yang didn't want foreigners to see their designs.

If you want to see the technology of foreigners in China, it is a dream, and even the appearance of the finished product will not be seen by Chinese.

Now these foreigners are watching their experiments in the artillery field, how to replace the barrel, and the detailed mechanism inside can be easily understood.

"You come with me to find Commander Qiu and drive the British out of the artillery field."

Immediately, Liu Yijiu took Yu Yang to the military region headquarters to find Qiu Yue and asked them to drive away the British who stayed in the artillery field, and Qiu Yue directly pushed the matter to the General Staff and the Logistics Equipment Headquarters.

This made Liu Yijiu angry, a Buddha ascend to heaven.

directly dialed the phone number of Li Yunlong's office and put forward his own request.

Li Yunlong is not unaware of the relationship between these technologies, but the internal situation is very complicated, and there is never a simple thing to do in transactions between countries.

"Since the higher authorities say that there is no way to drive out the British, let's stop." After this circle, Liu Yijiu accumulated full of anger.

When the construction of the equipment test site in the mountain is completed, no foreigner will be allowed to step into it in the future.

The Americans came, flying from the capital to Rongcheng, and by the time they arrived, it was already dark here.

It's still the same people, Liu Yijiu didn't go to the airport to pick them up, these guys don't keep their promises at all, if it weren't for their own inability to reverse develop the ultra-high-purity pure tungsten production process and new cannon steel provided by Liu Yijiu, the Americans would not have come back.

Even if he comes back, he will not look for Liu Yijiu again.

After the Americans had settled themselves in the Rongcheng Hotel, Tang Peilin of the Logistics Department and Wang Wanshan of the Ministry of Commerce personally came to Liu Yijiu's guest house and told Liu Yijiu that the Americans hoped to complete the deal they had negotiated in the last negotiation and then start some negotiations on the aircraft.

"Are they in a hurry? What's the hurry? Just let them continue to put pressure on the big guys above. By the way, I heard that the Soviets are in contact with it and are ready to redeem their MiG-25s from us? Liu Yijiu was already holding back the fire in his heart, and his tone of voice was a little rushed. (To be continued......)
