The country is broken

The battle is always going on, and the frequent attacks of the devils make the arsenal have to be moved frequently. The devils' planes often take special care of this Eighth Route Army arsenal, so the people in the arsenal often pack up their things and hide in the woods. Fortunately, there are not many things. It's nothing particularly important, pack lightly, put on mules and horses and leave.

Until a team of the Eighth Route Army discovered a huge group of karst caves in the depths of the Taihang Mountains, the extremely spacious caverns, the extremely hidden entrances and exits, and after a little modification of the lighting conditions, it was a unique hiding place. An order was given to move the arsenal, which can be called a key department, to the cave, and an engineer platoon was also helping to transfer it.

When Li Wei took the first step into the cave, he was startled by the strangeness in the cave and opened his mouth wide open for a long time. The topography of the cave entrance on the mountainside is easy to defend and difficult to attack, and it has a wide field of vision. Even if it is discovered by devils, as long as there is enough medicine and food, it can block it for a few months. The limestone rock tens of meters thick above the cave roof is enough to withstand any explosion Bombing and shelling.

"A good place, really a good place!~" Li Wei admired the scenery inside and outside the cave, but soon devoted himself to the reconstruction of the arsenal. The whole cave group is more than [-] meters long, with hidden cave entrances everywhere. There is spring water in the cave, and after several stalactites were blown up with explosives, several new caves were opened up.

Due to the large space in the cave, the higher-ups were more concerned about it. The arsenal was instructed to expand and develop, and planned to expand from the original repair department and refurbishment department to firearms repair, munitions production, gunpowder production, firearms research and development, and sub-refurbishment. main function. [

In addition to sealing and strengthening the cover to a relatively partial opening, a hidden fortification of the main entrance was built in combination with the area. Simple floors were built in the larger main cave, and lighting and ventilation were strengthened on the hidden external seams.

Repair the flow direction of the aqueous solution containing calcium bicarbonate in the cave, adjust the water channel, and greatly reduce the humidity in the cave. Li Wei and several maintenance personnel used strong magnets and metal coils to make simple generators and voltage regulators, and set them up on the Although the power of the main water channel in the cave is not high, it is enough to provide an endless supply of electricity for the lighting and communication in the entire cave.

The expansion of the arsenal has brought in many new comrades. There are almost a hundred people in the entire arsenal. In addition to blacksmiths and carpenters, there are people, but tools and materials are very limited.

Especially the current issue of gunpowder. The gunpowder and primer for sub-packs and the gunpowder for grenades are very scarce. Every gunpowder and explosives was transported by anti-Japanese fighters at a huge price or even at the expense of their lives.

According to the instructions of the Party Central Committee, self-reliance, hard work, and trying to solve the immediate gunpowder problem became the most troublesome thing for Li Wei. Because Li Wei was a newcomer to the arsenal and lacked qualifications, he had to be appointed as a technical consultant. What is a technical consultant? It’s just the people in charge who ask questions, at least that’s how Director Li explained it, because everyone can get answers and tips from Li Wei more or less when they encounter problems, and Li Wei has become an indispensable and important part of the arsenal , a master of arms and a powerful man in the eyes of everyone.

The arsenal originally had the treasure of the factory, the standard military production brochure of the Northeast arsenal of the Kuomintang Army, but the cultural level of the Nai arsenal is not high, and it is impossible to understand the content. Some chemical names and technical terms are not understood at all, and can only be produced simply. Some common medicines, but this military brochure is different in Li Wei's hands. Others don't understand, but he understands it. He knows exactly what's going on, but he can Combining the knowledge learned in the past according to the booklet has become a guide book for arms production.

There are various ratios of gunpowder, ordinary black gunpowder of mononitrate, disulfide, and charcoal, ammonium nitrate that can be used as fertilizer, conventional explosive TNT, professional RDX, special explosive 4, plastic explosive, and even banned starlight explosive , Li Wei is very clear about these formulas. In modern times, the composition of explosives can be found on the Internet as long as there is a heart, and there are even methods of making atoms.But here, in the Dashangou of Taihang Mountains, surrounded by ghosts outside, it is almost in a primitive state. The extreme lack of resources makes it difficult for Li Wei to cook without rice. Just take the common chemical raw material sulfuric acid as an example. A few yuan is a big bottle, you can buy as much as you want, and this ordinary sulfuric acid can no longer be ordinary, and in this era of the Anti-Japanese War, the chemical industry is generally weak in China, this stuff called sulfuric acid is almost heard No one has ever heard of it.

The blocking of the devils and the embezzlement of the national government made Li Wei's head bigger. He had no choice but to start from the most basic. The chemistry he learned before was all learned from the finished chemical raw materials, and the production of basic chemical materials But it is not deeply involved.

Temporarily organize a group of teams who are familiar with geology (it is said to be a team, just a few students from the geology department and a few mountain people who are familiar with the terrain), after Li Wei's special training, after being able to simply identify a few minerals, We set off and searched all over the mountains and plains for various natural chemical basic materials.

If it weren't for Li Wei, terms such as potassium permanganate and potassium chlorate would have stumped a lot of people.

God paid off, and finally someone found sulfur near the crater of an extinct volcano, and nitric acid was also found in a dry creek pit. A large amount of mineral materials were piled up in a cave in a cave. Thinking that these ordinary and insignificant things can actually play an important role in fighting the sun.

Toner is very easy to handle. After coking, the high-quality bituminous coal from Datong, Shanxi is sieved and ground repeatedly. Li Wei specially designed a set of gunpowder processing tools made of wood and quality, and in a special karst cave, skilled workers produce gunpowder. .

After many experiments and repeated verification of the chemical formula and ratio, Li Wei first synthesized nitroglycerin. With nitroglycerin, the most basic materials for drug production were obtained. Smoked nitrocellulose and TNT were quickly produced. Standardized The sub-drug granules and the grenade gun system have all been produced as samples. As long as the raw materials are not interrupted, the arsenal will be able to produce a large amount of munitions without interruption. Now the arsenal is just beginning to look like an arsenal.

A special military chemical laboratory was set up, and Li Wei brought some educated students, the production speed of the medicine was accelerated a lot, and many by-products benefited people even more. The General Assembly Department got the urgently needed dyes, and the hospital got Disinfection supplies and a small amount of western medicine products were unexpected by others. The expansion of the arsenal first benefited the Eighth Route Army itself.
