Life in the world of film and television

The frontline battlefield is so anxious, and the time will soon enter [-], and there will be more than eight months before Germany will blitz Poland, and World War II will break out in full swing.

Li Mu also began to step up his preparations, especially in terms of weapons. In addition to importing a large number of weapons, he also began to produce more weapons himself.

Six months ago, he established a weapon research and development institute, and started two projects at the same time, one is the imitation research and development of the grenadier.

As a small-caliber weapon carried by an individual soldier, this weapon uses simple materials, simple manufacturing process, and the cost is quite cheap. It took only two months for the weapon research institute to successfully imitate and develop it.

Four months ago, the mass production officially started. At the beginning, the monthly output was only [-] grenadiers. With the large number of machine tools and production and processing equipment imported by Li Mu, the monthly mass production has increased to [-] grenadiers. Tool.

Now, large-scale equipment of front-line troops has begun, and the output will further increase in the future, and even spread to infantry squads.

Another project was the development of the Sten submachine gun.

As a famous World War II gun, the production technology of this weapon is also simple and rough, and the cost is low. With technical standards, it is one of the few submachine guns that can be manufactured in China. During World War II, a total of more than 300 million submachine guns were produced.

According to the drawings provided by Li Mu, a group of professors and technicians spent more than five months finally completing the imitation work of this gun.

A month ago, the arsenal officially started small-scale mass production of this weapon.

Up to now, a total of hundreds of Sten submachine guns have been produced and have been sent to the frontline troops for testing to further improve this weapon and adapt to the domestic battlefield.

The next step is to mass-produce this submachine gun and install it in front-line troops.

After the development of these two weapons was completed, the Weapons Research Institute was not idle, and Li Mu handed them a new weapon, the Type [-] or [-] semi-automatic rifle.

A semi-automatic rifle is a rifle that automatically loads and loads bullets, also known as a self-loading rifle.The world's earliest semi-automatic rifle appeared in [-], and then various countries began to vigorously develop it, and many well-known semi-automatic rifles appeared.

For example, the M1 Garand rifle in the United States is a semi-automatic rifle that the United States began to develop in the 20s.It was also the standard rifle equipped by the United States during World War II. After World War II and the Korean War, by 1957, nearly 1 million M1000 Garands had been produced worldwide.One of the best semi-automatic rifles available today.

As for why Li Mu didn't buy this gun, it's because the price is a bit expensive nowadays. The price of an M1 Garand semi-automatic rifle can match the price of a Czech light machine gun.

Not worth it.

Not only the United States, but now the Soviet Union, Germany, France, and Britain... all have their own semi-automatic rifles, but they have not been deployed on a large scale to the frontline troops. This process began to accelerate after the outbreak of World War II.

In this day and age, there is no technical blockade or restriction. In theory, as long as the corresponding machine tools and production equipment are imported, semi-automatic rifles that can be produced abroad can also be produced domestically.

However, compared with imitating foreign semi-automatic rifles, you still need to pay patent fees. Li Mu set his sights on my country's first-generation classic rifles, Type [-] semi-automatic rifles.

In the last world, as a policeman, he participated in shooting competitions many times. Among them, in the rifle competition, he used Type [-] or [-] semi-automatic rifles.

Although it is not possible to quickly disassemble the firearm with eyes closed, Li Mu is very familiar with the various parts and structures of this firearm.

If you ask him to make it, he may not be able to make it, but it is still no problem to draw a rough blueprint.

Speaking of which, this gun is a Soviet-made SKS semi-automatic rifle imitated by our country in the 50s. It is light in weight, good in shooting accuracy, reliable in mechanism action, and comes with a folding bayonet.

It is also possible to equip individual soldiers with certain anti-armor capabilities by adding accessories to the muzzle, launching rifle grenades or throwing grenades.

This is also the first semi-automatic rifle to be installed in our army, and the Type 56 light machine gun and Type 56 automatic rifle are collectively referred to as the Type 56 gun family.

Border conflicts in the 60s, self-defense counterattacks in the 80s, this five-six-type semi-automatic rifle was still one of the main individual combat weapons of the army at that time, and it created countless legends of sharpshooters for our army.

With the current technology, it is naturally impossible to fully present the mature Type [-] and [-] semi-automatic rifles. If it is really presented in full, it is definitely the top individual weapon in the world today.

However, even if the quality and accuracy drop a bit, as long as it can be produced, and the Type [-] and [-] semi-automatic rifles can be mass-produced by themselves, the quality drop is not unacceptable at all.

Today, the design drawings of this weapon have been handed over to the Weapons Research Institute for them to study the imitation and finally achieve mass production.

After all, the use of Mauser 98k is not a long-term solution. After the outbreak of World War II, it will be difficult to purchase it again. It is better to produce it yourself.

On the other hand, as the mass production of penicillin gradually stabilized, the R&D team that completed the mass production of penicillin not only stayed idle, but also grew in scale. Li Mu divided them into several groups, each responsible for new tasks.

First, a group is responsible for the mass production of sulfonamide.As an antibacterial drug, sulfonamide is a strategic material that is in short supply, and it is also one of the materials that Li Mu purchased from abroad. The purchase of sulfonamide alone has consumed a lot of money in the past year, and sometimes it is even impossible to buy it.

Although you can earn more by bringing it to China, it is not as convenient as producing it yourself.

The most important thing is that although today's sulfonamide is energy-produced, the technological level is not high, resulting in high production costs and poor quality, but the price is very high.

However, in the 21st century, the drug sulfonamide is not only about to be phased out, but the production methods are all rotten.

He knows a lot about various simpler production methods and processes, and the cost is very low, even less than one-tenth of the current production cost, and the quality is better.

Since today's production costs are so high and the market is so big, it is not appropriate not to plug in. Sell it at a discount and sell it cheaper, so you don't have to worry about no market.

At the same time, this is also a source of income with great potential. At the very least, as long as no other pharmaceutical company can find a more advanced mass production process than him, no pharmaceutical company can compare to the price and quality with low domestic labor costs. .

For the item of sulfonamide alone, it is no problem to eat a seven or eight year bonus.

The other two R&D groups developed streptomycin for the treatment of tuberculosis and praziquantel for the treatment of schistosomiasis according to the information provided by Li Mu.
Streptomycin is an aminoglycoside antibiotic. In 1943, Selman Waxman, a doctor of the University of California at Berkeley and a professor of Rutgers University, was isolated from Streptomyces. It was the second antibiotic produced and used clinically after penicillin, and Waxman was therefore Received the 1952 Nobel Prize in Physiology or Medicine.

Streptomycin's special effect against tuberculosis bacillus has created a new era of tuberculosis treatment.Since then, the history of Mycobacterium tuberculosis wreaking havoc on human life for thousands of years has been hoped to be curbed.

This drug also has huge market potential, but it was produced later than penicillin. It was not until the 50s that the extraction technology was further improved and mass production began.

In this era, the mass production of streptomycin is naturally very complicated. In the 21st century, the mass production of this drug is too simple.

Li Mu wrote down the specific production method and handed it over to the R&D team to try mass production in this era, striving to become a major source of income after penicillin.

In addition, in this day and age, schistosomiasis is very common, especially in China.For example, in the 50s, there was a large-scale outbreak in the southern region, commonly known as the big belly disease, and the color changed when talking about it.

Praziquantel is a broad-spectrum anthelmintic synthetic drug discovered abroad in the 70s. After learning that it was effective against schistosomiasis, it was trial-produced in China in the same year.It has been used on the market for more than 30 years, and has been used as the main drug against schistosomiasis and an effective drug against other parasites. It has been used in the first-line clinical application and has played an important role in human health.

In the future, there will be many simple ways to produce this drug, and mass production is completely possible with the technology of this era.

The last R&D team is to develop and mass-produce praziquantel based on the information provided by Li Mu.

With these three miraculous drugs that are widely used in this era, they will definitely be able to obtain large sums of money and create this era in their own way.

In the afternoon, Li Mu came to the officer's short-term training class to watch the tactical drill.

Looking at the figures off the field, first a soldier poked his head out to check, and took the lead to charge up. The eight soldiers around him also divided into three groups, and rushed up from different directions.

With vigorous movements and skilled tactics, Li Mu nodded. It is indeed the classic three-three system tactic of our army in the future.

This tactic first originated in the Anti-Japanese War, matured in the Civil War, and was widely used in the Korean War. It is one of the core tactics of our army's infantry training program and is mainly used in infantry squad assault tactics.

It once shined brilliantly on the Korean battlefield. The Volunteer Army relied on this tactic to make American soldiers suffer a lot with simple weapons and equipment. Once the Korean War was over, the West Point Military Academy of the United States included it as a classic teaching case.

Today, this kind of tactic has not yet appeared. Li Mu also sorted out some simple methods of three-three tactics based on some materials he had read before, and handed them over to the officer training class for them to practice and perfect themselves. The results are not bad.

This tactic takes squads as units and divides them into three battle groups, each with three people. In order to facilitate mutual support, they are generally arranged in three echelons.

The three-person combat team formed a triangular offensive formation, and each soldier had a clear division of labor, attack-cover-support.The squad leader, deputy squad leader, and team leader each lead a combat team to act.

When the combat team attacks, two soldiers are in front and the team leader is behind, forming a triangular formation. Three combat teams form a combat squad, and three combat squads form a combat group. When attacking, they form a "skirmish line" formation. Change the battle formation at any time according to the instructions of the team leader or squad leader...

After watching the tactical drill and looking at the booklet summarizing the complete three-three system tactics in his hand, Li Mu nodded.The pamphlet will then be issued in large numbers and provided to troops at the front, as well as troops to the north.

Recently, cooperation with the north has gradually increased, such as oil mines.

In the Yan'an area of ​​northern Shaanxi, there are records of oil dating back to the Han Dynasty 2000 years ago.At that time Yan'an was called Gaonu County, and the Yanhe River was called Weishui.Ban Gu, a historian of the Eastern Han Dynasty, wrote in his book "Hanshu·Geography": "Gaonu in Shangjun has Weishui, which is flammable."

During the Northern Song Dynasty, Yan'an was called Yanyan Road.Shen Kuo, a famous scientist in the Song Dynasty, when he served as the economic envoy of Yanlu, conducted a careful inspection of the Yan'an area, and also came to the conclusion that there was oil in the territory of Yanyan.In his book "Mengxi Bi Tan", he used the concept of "oil" for the first time: "There is oil in the territory of Yanyan, and the old saying is 'Gaonu County produces fat water', that is... this thing must be Daxing in the world... Covering the most oil, it is born in the ground endlessly, not like pine wood that is sometimes exhausted."

By the beginning of the 20th century, oil began to "popular in the world".Cao Hongxun, the governor of Shaanxi, once again advocated "to use Yanchang's kerosene to compete with foreign kerosene", and Yanchang Petroleum "has to be managed on its own, and it cannot be coveted by outsiders." In 1904, Cao Hongxun's request was finally allowed.The Qing court allocated more than 8 taels of local official silver as the start-up fee.

On June 1907, 6, the first oil well in China was drilled outside the west gate of Yanchang County. After 5 months, when the depth was drilled to 3 meters, the well saw oil, and when it was drilled to 69 meters, the well was completed and the daily crude oil output reached 81~1 tons.Back then, when the kerosene refined by the Yanchang Petroleum Plant was sent to Xi'an, the kerosene gas lights were shining brightly, like a small sun in the dark night, which caused a sensation in the city of Xi'an for a while.

In 1935, the weather-beaten Yanchang oil mine fell into the hands of the north. They had no money to buy machines for oil extraction and refining, so they could only use the most primitive methods, which could collect hundreds of tons of oil a year.

Then use the oil to produce gasoline, kerosene, paraffin, ink, gun oil, vaseline and other products, which not only guarantee the oil demand of the government agencies and the military and civilians in the border areas, but also sell a batch of them as funds for the north.

However, the annual output of hundreds of tons of oil seems to be a lot, but it is actually very little.Li Mu can purchase [-] to [-] tons of gasoline when he travels abroad casually, which is really not enough.

However, the future must also be considered. If the air route is interrupted, self-sufficiency must be achieved. This is true for weapons and energy.

Coincidentally, seeing Li Mu's energy, all kinds of foreign weapons and commodities can be purchased, and the North also intends to cooperate to develop Yanchang Petroleum together, and the two hit it off.Li Mu is responsible for the procurement of oil extraction and refining equipment, while the north side is responsible for production.

Although, he doesn't look down on the current output, with oil extraction and refining equipment, the output is more than this.As far as he knows, after the 21st century, the Yanchang oil field is still not exhausted, and the annual oil production basically exceeds [-] million tons, with great potential.

As a result, Li Mu also had more ideas. The key to the poor and weak country lies in the lack of industrialization. Not enough.

With penicillin and several other drugs, he will not be short of money in the future. He can purchase all kinds of machinery and equipment to improve Nanyang's industrial system.

However, there is still a weakness. Nanyang has a large land area of ​​nearly [-] square kilometers and a large enough population. The influx of so many westward migrants has already exceeded tens of millions, including a large proportion of intellectuals and workers.

There is no shortage of workers, no shortage of factory machines, but there is a shortage of necessary raw materials, such as steel...

However, Nanyang is short of materials, but the north is not short... As far as he knows, although the ground in the north is barren, the bottom is full of treasures, and there is no shortage of coal, steel, and oil.What's more, if you go further north in northern Shaanxi, you will find Ordos and Baotou, and countless energy and minerals are also buried underground.

Not only in northern Shaanxi, but also in the Shaanxi-Gansu-Ningxia border area. Although the grain output is not high, there are a lot of good things buried underground. It is an excellent raw material base.

The north is responsible for raw materials, and Nanyang is responsible for production, which just fit seamlessly.

After the communication between the two sides, the North is naturally very happy, but whether it is an oil field, a metal mine or a coal mine, they are all things that make people jealous, especially if it is in the hands of the North, can the Guofu see it?

In the final analysis, whether it can be defended depends on force.

Coincidentally, the weapons purchased by Li Mu began to arrive one after another.Whether it is to resist Japan or lay the foundation for the country's industrialization, it is necessary to strengthen the strength of the north.

Li Mu directly dispatched 98 Mauser 2k, [-] grenade launchers, and a batch of M[-] heavy machine guns, Czech light machine guns, mortars, howitzers... and sent them over.

Along with it, there are two firearms production lines, three bullet production lines, one mortar production line, and two grenade production lines... Enriching the war potential and self-sufficiency in the north.

With the quality of the soldiers in the north, with these weapons and production lines, not to mention fighting off the little devils, and resisting the threat of the Guofu, it is no problem to take over the control of some areas in Shaanxi, Gansu and Ningxia from the hands of the Ma family in the northwest.
