However, before the explosives project was launched, Li Yun first had to establish a black powder factory, because the technology and equipment conditions for yellow explosives were not yet mature, but it was much easier to prepare black powder. With the high-quality saltpeter and sulfur from the Black Stone Ridge and the Bat Cave, the two important raw materials for the manufacture of black powder are guaranteed, and as for the charcoal, Canglan Mountain has wood, and you can fire it yourself.

Black gunpowder is a low-speed explosive, although the power is relatively weak, but as long as the amount is sufficient, the lethality is still very considerable. Moreover, even if yellow explosives are successfully developed in the future, the output will not be too high due to technical conditions, so the gunpowder used by the Suzaku Army in the future will still be dominated by black gunpowder, and black gunpowder is also an important firearm firing drug before the invention of smokeless gunpowder.

So Li Yun immediately ordered Wei Ning to call the engineering team, Guo An, Mao Dawei, and Bao Maocai, these three people were the three squad leaders of the engineering team, and they were also the supervisors of the gunpowder factory selected by Li Yun.

"Big brother!"

Soon Guo An, Mao Dawei, and Bao Maocai came to Li Yun's tent.

Li Yun immediately glanced up at them, "Guo An, I remember that you used to make fireworks, right?" ”

"Yes, big brother, our family has been a fireworks craftsman for three generations." Guo An arched his hand and said.

Li Yun nodded when he heard this, the reason why he chose Guo An to be the director of the gunpowder factory was precisely for this reason.

Then Li Yun took out a document and said to Guo An: "This is a recipe and process flow chart of black gunpowder, the three of you take a look at it and memorize it." ”

"No!"

When Guo An and the three of them heard this, they immediately took it and studied it.

There were two gunpowder formulas that Li Yun handed over to Guo An, one was granulated black gunpowder and the other was maroon gunpowder. Granulated black gunpowder is powerful and can be used as a bomb filler, while maroon gunpowder burns relatively slowly, so it is not easy to explode when fired as a firearm.

In fact, Li Yun is quite helpless, the craftsmen in this world are very skillful, but they don't know any theoretical knowledge, they only know what they are. Therefore, Li Yun has to do many things himself, the soap factory is like this, although Li Yun told those workers about the manufacturing process and process of soap, but he still has to help guide him, otherwise it is difficult for those workers to quickly grasp the mystery.

In the past, the Suzaku Army had just formed an army and the Tiger Army was pressing forward step by step, so Li Yun's focus had always been on military training, and he was not very concerned about the engineering team. just threw them a copy of basic engineering materials, and some modern factory production management materials, and basically let Chen Muyu and others learn by themselves. However, Chen Muyu and others are older, and the level of self-study is indeed a little touching.

Now, with the Vermilion Bird Army gradually on the right track, and the disappearance of external threats such as the Huwei Army, Li Yun decided to shift his focus from military training to industrial development.

After a long time, Guo An and the others handed the document back to Li Yun and said, "Big brother, we have already written down the contents on this. ”

Guo An was originally a skilled fireworks craftsman and had a lot of experience in the preparation of gunpowder. It's just that the gunpowder in this world is still a little primitive, and it has not yet reached the best ratio of gunpowder, and the technological process is not the most scientific, but it is also very close. So after seeing Li Yun's information, Guo An and the three couldn't help but have a feeling of being stunned.

After receiving the information, Li Yun immediately advised: "Remember that this information can only be mastered by the three of you, and you can't tell any other person to understand!" ”

"No!"

When Guo An and the three of them heard this, they immediately responded.

Secrecy has always been something that Li Yun has repeatedly stressed, whether in daily training or regular meetings, Li Yun has emphasized it many times, and has even promulgated a set of special regulations on secrecy for the whole army. Therefore, whether it is making soap or dispensing gunpowder, Li Yun only teaches the formula process to a few people, and after these people master it, they are in charge of production in stages, while ordinary workers only master the process they are responsible for.

Not only that, in the engineering team, Li Yun not only promulgated the general secrecy regulations, but also the special production secrecy regulations, stipulating that all workers are not allowed to inquire about the news outside the process they are responsible for. The purpose is to ensure that these important formulas and processes of the Suzaku Army will not be proliferated and leaked in the future.

For this reason, Li Yun even transferred elite soldiers and strong generals to become a professional secrecy protection organization, the Secrecy Bureau!

Then Li Yun gave Guo An and the others a warrant, "This is my warrant, you immediately find Chen Muyu to transfer manpower to establish the gunpowder factory as soon as possible to carry out production." ”

"No!"

After Guo An and the three of them went out, Li Yun couldn't help but breathe a sigh of relief, unlike the production of soap, the production of soap is a completely unfamiliar field, and the people of the engineering team have never set foot in it. Therefore, Li Yun must personally guide and use his mobile phone to check information and solve problems at any time, otherwise it will be difficult for those workers to produce finished products in a short time. Unlike gunpowder, Guo An was originally a skilled fireworks craftsman, and he had a lot of experience in preparing gunpowder, but what he lacked was only a scientific formula and a reasonable process, as well as some small skills in handling materials.

All of this is nothing more than a thin layer of window paper, which they can fully grasp with a little mention.

After Guo An and the three of them went out, Li Yun couldn't help but think in his heart, since he decided to turn his focus back to industrial production, many things had to be changed.

In fact, Li Yun also taught the theoretical knowledge of the engineering team, but these people are old, their learning ability and comprehension ability have declined significantly, and they can't understand Li Yun's dry mouth, so Li Yun finally gave up. However, although these people have poor learning ability, they are all old brothers who have been following him during the riots, and each of them is loyal enough.

Therefore, in Li Yun's vision, although these people cannot become research talents, they can become the backbone of the core secrets in various factories in the future, such as soap factories and gunpowder factories.

At present, whether it is a soap factory or a gunpowder factory, its scale is relatively small, and the total number of people will not exceed 20. Because these twenty people do not exist as ordinary workers, but as technical backbones. After these people have mastered the technology of gunpowder and soap, they can expand the scale of the gunpowder and soap factory by adding ordinary assembly line workers to it.

Moreover, if the Suzaku Army wants to develop in the future, it is impossible to have only two factories of gunpowder and soap, and countless factories will be established in this Canglan Mountain in the future. Therefore, the old brothers of every engineering team are very precious, and Li Yun will not waste too much in one factory.

Therefore, for the sake of future development, Li Yun decided to divide the engineering team into several technical research groups, and each group asked them to be responsible for a black technology, such as cement, glass, earth-based steelmaking, Chinese patent medicine, printing, porcelain, textiles, and so on. It's like a soap and gunpowder factory, where all the technical secrets are concentrated in the hands of loyal brothers.

Of course, things have to be done one by one, and the road has to be taken step by step, Li Yun doesn't expect them to really understand these black technologies, but at least they must be familiar with those technical materials. Anyway, there is a lot of time now, and Li Yun can't set up so many black technology factories at once, let them memorize the information first, and then wait for Li Yun to lead them to build one by one in the future.

But in addition to this, the most important thing is the cultivation of research-oriented talents, and the old brothers of the engineering team are older, so they only need to be senior technicians who know some practical techniques. However, the development of the Suzaku Army cannot only rely on these people who understand what it is, but do not know why it is, and Li Yun will not be able to soak in the factory all day in the future, so for the healthy development of the Suzaku Army, the cultivation of research-oriented talents in various science and engineering disciplines must be put on the agenda as soon as possible.

At present, it seems that it is far from enough to run only one military school, and it is necessary to run a specialized institute of science and technology, but since it is necessary to run it to the end, and all kinds of colleges and universities should be run, the province will be temporarily clinging to in the future.

And Li Yun has a characteristic, that is, as long as he thinks of something, he will do it immediately, and even if he can't finish it, he will build a shelf first, because even if there is only one empty shelf, it can be slowly improved in the future, which is better than being busy and forgetting it.

So after deciding that, Li Yun immediately took action, first he first sent an order to Song Dacheng, asking Song Dacheng to step up the search for all kinds of craftsmen, and select a group of 12 to 16 years old, smart and clever teenagers who are preferably literate and sent back to the mountains. The second is to divide the engineering team into a number of technical teams, and give them the black technology materials that have been copied before, so that they can study them at least by heart.

However, like the formula process of gunpowder and soap, these must be kept strictly secret, so Li Yun wants the Secrecy Bureau to set up a database, and all important information will be stored in it in the future. If the members of the engineering team want to see it, they can only look at it in the museum, and they cannot bring it out, let alone copy it. In addition, some insurance measures are set up, and if necessary, even if the entire library is razed to the ground, it is necessary to ensure that the materials inside are not lost.

After instructing everything, Li Yun threw himself into the intense cause of copying books, and this time Li Yun decided to establish all kinds of colleges and universities, so the task of copying books was very heavy. There are not only basic textbooks for primary, middle and junior high schools, but also professional textbooks for various colleges and universities.

However, Li Yun didn't have time to spend more than ten years cultivating talents, so Li Yun streamlined all the teaching materials and removed many unused content. Even so, Li Yun plans to divide all kinds of colleges and universities into short classes, and shorten the tutorials as much as possible, so that they can master the theoretical knowledge in a field in the shortest possible time, and at least be able to understand the materials, so that Li Yun can be liberated from the front line of the factory. The long class is cultivated step by step, which can be regarded as a reserve of talents for the future.
