Jiang Chen had a very comfortable life at home for a few days, if it weren't for B17 to urge him to go back, he might not be happy. Eating every meal made by his mother, enjoying the warmth when his parents are there, and often asking Liu Yun to have a little romance, what a beautiful thing it is. The only thing that makes Jiang Chen regret is that Jiang Chen did not succeed in further matters with Liu Yun, since Jiang Chen once took advantage of Liu Yun's inattention to secretly kiss her, every time he meets Jiang Chen, he will follow Li Siyu, a super light bulb, in her words, to prevent the evil forces from attacking the progressive young woman again, Jiang Chen burst into tears!

Jiang Chen also secretly asked Liu Yun the reason, and when he asked, he realized that he couldn't blame Liu Yun but the result of his own work (zuō). It is said that after being successfully "sneak attacked" by Jiang Chen that day, Liu Yun's heartbeat accelerated for a long time, and he was often in a daze and blushed. Naturally, this matter can't be hidden from her good friend Li Siyu, under her "Ten Tortures", Liu Yun finally blushed and told Li Siyan that Jiang Chen secretly kissed her, which made Li Siyan hate Jiang Chen's behavior, and from then on, she strictly guarded Jiang Chen and did not let him have a chance. After suffering N failures, Jiang Chen finally couldn't help but look up to the sky in pain and shouted: "Lei Heizi, where did you die, come back and collect this goblin." ”

Somewhere on the southern border, Lei Jun, who was lying on his stomach in the grass on a mission, suddenly sneezed a few times without warning, and he said depressedly: "Who is talking about me, is it Siyan? Is she thinking about me?" Lei Jun fell into a short contemplation.

"Captain, the enemy's convoy has appeared, preparing to assemble and hide. A soldier's voice interrupted Lei Jun's musings.

"Oh, I'll see. Lei Jun picked up the binoculars and began to look down the mountain, and sure enough, he found that in the valley under the mountain where they were hidden, there was a Nanban transport convoy parked there, and some Nanban soldiers were cutting down branches to hide. He put down the binoculars and nodded and smiled: "Sure enough, it's them, we have worked hard for so long to finally catch them, go and report the coordinates and directions to the front finger, and let them mobilize artillery to bombard." ”

"Yes. The warrior replied. After a while, the cannonballs flew over with a whistling, and the whole valley was immediately in a sea of fire, and some of the ammunition that was still on the car was also detonated because of the fire and explosion to form a secondary explosion, a shoe soldier was killed or directly blown up and fell like a heavenly maiden scattering flowers, some of them were stuck to the body by the splashing oil, and instantly ignited into a burning man on the ground in pain, at this time the valley seemed to become a purgatory on earth, miserable!

At this time, a middle-aged soldier crawled out of the explosion site with difficulty, his swarthy face was particularly frightening, he wiped a smoked same black telescope with his clothes that had been blown into rags, and then carefully looked at the surrounding mountains and forests, he knew that this shelling was so accurate and timely that there must be enemy scouts moving on the surrounding mountains, and suddenly he turned to a mountain forest and showed a penetrating smile.

Back to Jiang Chen, he has now returned to B17, because he is ready to negotiate with his father Jiang Keming's research institute, after all, this is the cooperation between two enterprises or institutions, not between him and his father, so both parties are responsible for their own enterprises or institutions.

At first, Jiang Chen's plan was rejected by both enterprises and institutions, because neither of them had ever tried to cooperate in this way, and besides, how could a state-level scientific research institute cooperate with a military factory that was about to close down? However, under Jiang Chen's insistent introduction, both sides began to hesitate, and Jiang Chen decided to make more efforts.

He was relatively successful in the B17, because everyone saw the success of the previous project, what is it? camouflage uniforms and sniper rifles. Although the sniper rifle has not yet been ordered, it has become famous, and now the entire military industrial system in the northwest and even the whole industrial system know that there is a small factory on the verge of bankruptcy in Anxi that is angry and strong, and finally made a good gun after hard work, I heard that even the military / committee head / chief is full of praise.

With these foundations, Jiang Chen's work is relatively easy, but what the leaders and workers in the factory do not understand is why they should cooperate with the scientific research institute to develop it, isn't it just a bazooka? They are talking about the 107 rockets that are still being produced by their own factory, and they think that this is similar to the rocket launcher technology that is about to be developed, so there are objections to Jiang Chen's pulling in the scientific research institute for joint development, is it that your father is here in the scientific research institute, and you deliberately want to help them?

Jiang Chen was also a little helpless about this, no way, everyone would have thought about this in this way, Jiang Chen couldn't go around and advertise that I was laying the foundation for long-term in-depth cooperation in the future! But what to produce can't be said now, in case it is spread out and developed and produced by others in advance, Jiang Chen It will be difficult for them to produce again, others will sue Jiang Chen for plagiarism, Jiang Chen doesn't want to cause this trouble, he just told his thoughts to the most core leaders, and those leaders immediately supported Jiang Chen after hearing Jiang Chen's reasons carefully, they didn't expect this young man to have such a long-term vision.

However, there are some difficulties on the side of the research institute of the Aviation Academy, after all, it is a research unit with a national prefix, so the people inside are relatively uninterested, or very disdainful, they think that we are also involved in the development and production of rockets and missiles and other important weapons of the country, and now we want to cooperate with a small military factory that is about to close down, are you joking? But there are still some people among them who understand, and they know that this is undoubtedly a matter of relief for them who are relatively difficult at this time. Participating in this project can kill two birds with one stone, one can take the opportunity to train our young researchers and let them grow up as soon as possible. Second, you can get a part of the funds, although it is not much, but it can also support one or two projects to continue, or improve the lives of employees, although Jiang Chen's father's position does not need anything, because he has a special allowance from the state can not care about these, but the grassroots researchers are very hard, they have no other income, all rely on wages to live, once there is a month of no salary, then it is difficult for their lives to continue.

Thanks to the efforts of these people and Jiang Chen and Jiang Chen's father, Jiang Keming, the cooperation plan was finally approved, and the negotiation between the two factories entered the stage of actual consultation. But once the actual profit is involved, the two sides are still communicating and interacting with each other in the last second, and the next second is a war of words and words against each other. At this time, it was inappropriate for Jiang Chen to intervene again, so he resolutely refused to go after participating in a consultation. Anyway, the technology and cooperation methods are almost discussed, and now there is only the division of commercial interests, and he can't say anything about this, so it is better to go back and rest and accompany his parents and girlfriend Liu Yun.

Finally, the two sides finally reached an agreement after an unknown number of consultations, Jiang Chen didn't know how many times, and he didn't bother to care. I just think this is so troublesome, can you do it in a few clicks like a man, I have to toss it like this. Hearing this, the father scolded with a smile, do you think that the child is playing at home, this project involves the actual interests of both sides, and you must be cautious, no one knows how much this decimal point will represent. How many years later did my father's prophecy finally come true, because the decimal point of the two sides was miscalculated, resulting in a loss of hundreds of millions of dollars on one side, for which the leader who participated in the negotiation almost committed suicide in shame, but fortunately was rescued in time, of course, this is only an afterthought.

Now, the two sides have actually cooperated, of course, Jiang Chen played a trick in the negotiation and settled the joint research center in B17. In Jiang Chen's words, it is so close to the production workshop, there are many excellent workers, once there is any good plan, it can be produced for testing, and the test site here is also very convenient. Of course, the research institute is not a fuel-efficient lamp, and the food and accommodation of these researchers are directly allocated to B17, since you are so enthusiastic, then take it together, and it can also reduce the burden on my side.

As the original proposer of this project, Jiang Chen was naturally selected into the project team as a deputy leader, which was named by the institute, saying that his thinking is clear and forward-looking, and will play a great role in the entire project team. And Jiang Keming also joined the project team and became the team leader, but he was just a name, and he didn't participate in actual research, and the aviation institute and scientific research institute would not let him do extra money no matter how short of money. Although many research projects have been discontinued, there are still many key projects in progress, and as a senior engineer in the hospital, his superiors have personally named him to participate in the responsibility, so he has no time to participate. And now there is a researcher over there who is the deputy team leader and is jointly responsible for Jiang Chen, and Jiang Chen also gets along well with this deputy team leader.

The direction of their research has been determined, that is, to develop a new type of individual rocket launcher and supporting rockets. At present, many plans have been put forward, several of which are relatively mature, for example, there is a plan to rely on the now mature 107 rocket, on the basis of which a new 110 mm rocket launcher is developed. This is the simplest and less risky option, and can be successful with a few modifications. Another option is to develop a portable 80 mm rocket launcher, which is simple, straightforward and practical. However, this meant that it had to be redesigned and experimented with, and there were also requirements for materials, and no one had much experience in this area, so everything had to be started from scratch. There is also a 120 mm bazooka, which agrees with this plan and believes that it is necessary to create a powerful and one-time solution to the target. In the end, under everyone's endless discussion, Jiang Chen made a decision, then build the most awesome! So the 120mm bazooka and supporting ammunition were put on the agenda!

Just when Jiang Chen and the others were developing the 120 bazooka in a hurry, the receipt letter from the General Logistics Department and the Commission of Science and Technology finally came, and Jiang Chen walked out quickly regardless of the participating scientific researchers who were in a meeting to discuss.

PS: What will be said in the receipt letter from the General Post and the Commission of Science and Technology, is it a success or a failure? Can the 120 bazooka be successfully developed? And whether Jiang Chen's request will be approved, please stay tuned! Say it, start trying two more! I'm working hard, to be honest, it's really not easy, especially if you write a technical article, you have to check the good information, maybe someone else has written a few chapters, I haven't finished a chapter, plus I'm a super handicap, I usually look at the keyboard typing, and the speed is even more sad! So it's really not easy, so please support me a little bit. (Finally, I want to complain, why no one has joined the group? I'm thinking about everyone in the group!)
