Li Rujin stayed in Zhoushan for another three days, and the relevant generals and military technicians of the Dawen Empire finalized the final shape of this submarine, and this submarine was officially named "Haijiao". "Change one" is "Haijiao No. 1".

The navy is extremely satisfied with this submarine, and it is now going to pull the "Haijiao No. 1" back to the troops, directly serve, and join the combat sequence of the navy, but it was rejected by Zhoushan, "Haijiao No. 1" is only the basic model of the Haijiao-class submarine, and it has a more important mission, as a prototype boat, to provide a reference for the research and development of subsequent models.

At the same time, "Experiment 1 and Experiment 2" entered the refit procedure, and it is expected that they will be delivered to the Dawen Imperial Navy in a month. The navy considered the situation in the long run and agreed to the Zhoushan proposal. Be patient and wait for a month.

As for the hulls of the three submarines in Huludao, they will be transported to Zhoushan by tugboats and reassembled in Zhoushan, while the engines will be produced by the imperial capital, after all, the production technology of the imperial capital is more mature.

The bureau will form Huludao to be responsible for the production of the hull, the imperial capital is responsible for the production of engines, and Zhoushan is responsible for assembly and research and development, forming a corresponding submarine production industry chain, although it is more troublesome, but to ensure that the submarine technology is not leaked. The most core technologies are all on the side of Zhoushan.

Originally, Zhoushan, as a research center of the navy, had a very high level of secrecy, but this time the security level has been raised, and the Zhoushan shipyard has completely become a secrecy unit.

Before leaving, Li Rujin left a proposal to the Zhoushan R&D Center, suggesting that the R&D center study medium and large submarines, which will be the main force and main deterrent force in future maritime wars.

At the same time, the self-sustaining power and diving depth of the submarine will be intensified, and the diving depth of the Haijiao-class submarine is only 120 meters, which may become the Achilles' heel of the Haijiao-class submarine in the war.

The diving depth of the Haijiao-class submarine is completely restricted by the material science of the Dawen Empire, and if you want to improve the diving depth of the submarine, you must have special steel with a high degree of yield, and materials science has always been the short board of the Dawen Empire, and there is still a long way to go.

Materials science comes to mind. Li Rujin couldn't help but think of the production of special steel and special steel, although the Dawen Empire was introducing Europa's steel production line, there was a lot of room for improvement in the output of steel.

In particular, the output of special steel has been greatly improved, but the variety is single, and only a limited number of special steels can be produced, which cannot meet the requirements of military development at all.

So the submarines of the Dawen Empire could only dive to a depth of 120 meters, reaching the limit of materials. If you want to break through the diving limit of the submarine, you must make a breakthrough in materials science, materials science, and materials science, Li Rujin is secretly ruthless, this time back to the imperial capital must set up a special materials science research and development center.

Li Rujin, who returned to the imperial capital, just arrived at home, and was scolded by his mother for splitting his head and covering his face, and he didn't even come back for his son's first birthday, wanting to rebel against God! The mother here just finished scolding, and Li Rujin was embarrassed by the two wives who complained about it, and even swore with a gambling curse, which calmed the anger of the three women.

even signed a lot of unequal treaties to let Li Rujin escape. Li Rujin, who had just escaped, went to tease his two sons, but the result was even more tragic, the two sons didn't remember him at all, and a cry made Li Rujin touch the ashes of his nose.

Li Rujin left home in embarrassment and walked towards the research institute with a chatter all the way.

When he arrived at the institute, Li Rujin found that the institute had changed a lot, and when he asked someone, he found out that the institute had been successfully split and divided into five R&D departments with five different R&D centers. It is only used as a general office.

Li Rujin found the office of the machine tool R&D department, identified himself, and then went to the new site of the machine tool R&D center in the suburbs of the imperial capital under the leadership of the staff. The R&D center is very large, covering an area of hundreds of acres, most of which are still vacant land, and there are few buildings.

Li Rujin followed the staff to the office of the R&D center, and the R&D personnel who received the notice also came out of the laboratory and were rushing to the office. The door opened and came in by Li Rujin's old acquaintance, Hou Dashan, a man from Sichuan.

The two hadn't seen each other for a long time, and after some pleasantries, Hou Dashan took Li Rujin to see a CNC machine tool controlled by Chinese character programming. After some understanding, Li Rujin has a certain understanding of Chinese character programming.

The bottom layer is still binary, which is the mechanical language of 0 and 1, and then it is compiled and converted into Chinese characters, which alone takes a lot of effort from R&D personnel, after all, Chinese characters are not like English letters, there are only twenty-six, and then these twenty-six letters are combined into English words.

The basic strokes of Chinese characters are only horizontal, vertical, apostrophe, pinch, fold, and dot, but there are more than 3,000 Chinese characters that are composed, and the combination form has upper and lower structures, left and right structures, etc., and the scope involved is extremely huge.

The compilation of Chinese characters made the R&D personnel of the Dawen Empire very nervous, not to mention the work behind. Li Rujin secretly praised these R&D personnel, this work is not only hard, but also tedious and boring, and those who can complete this work have great perseverance.

Li Rujin put his mind on the demonstration of the machine tool, and Hou Dashan opened the machine tool and began the demonstration work. In general, this set of control programs can only complete some simple operation instructions, and there are a large number of repetitive steps, and most importantly, these instructions need to be completed manually.

In Li Rujin's eyes, this machine tool is like a child's toy, but this set of Chinese character compilation program, is hard to come by, creating a new era, since you can use Chinese characters to compile mechanical programs, then you must also be able to compile computer operating system programs.

At present, there are no computers in the real sense of the word in the Dawen Empire, and some are also simple arithmetic machines, and they are not produced by the Dawen Empire, basically from the Europa Empire or England.

Li Rujin began to consider whether to set up a part of the Dawen Empire to develop computers, but Li Rujin was a little hesitant in his heart, he didn't know what kind of things would come out if he used Chinese character compilers to develop computers.

If this development continues, there will be a completely unfamiliar computer system beyond Li Rujin's control, and what kind of development will this system have in this world?

It can be said that the emergence of computers has rewritten history, and the huge auxiliary role of computers in science has kept tempting Li Rujin, making Li Rujin constantly entangled.

If the advent of nuclear weapons has changed the pattern of warfare, then the advent of computers will change the pattern of the world.
