Li Zicheng's team and the Manchu Qing Dynasty both sides are in full swing, whether it is to increase their own combat effectiveness or to weaken the combat effectiveness of the Ming army, such a rush purchase is indeed a simple and effective way, even if it is impossible to transport these guns and ammunition back, it is better to destroy them on the spot than to fall into the hands of the Ming army to harvest their own people's lives.

Compared with his opponents, the efficiency of the Ming Dynasty is much slower, and half a month later, although everyone in the court has basically reached a consensus to continue to buy more guns from Huapi, the problem is money? Half of the silver taels and supplies from the last transaction have not been paid......

And now the focus of everyone's debate is where to squeeze out the silver taels to buy more flower skin guns and ammo!

It is impossible to squeeze out money from the treasury to buy, and now the treasury of the Ming Dynasty is empty, and even the rats don't want to stay there, so there is only money and grain materials from the provinces to trade like last time, but after the Songjin War, the situation in the provinces is not optimistic, and some provinces have even emptied the treasury silver and grain, in case of any natural disaster [***]......

There were many reasons for the poverty of the Ming Dynasty, but the two most important ones were the loss of control of the feudal dynasty over the economy of literati and doctors, and a large amount of land was controlled by these vested interest classes who did not need to pay food and silver, which made the money and grain that could be received every year less and less; And the other is the suppression of the commercial economy, especially the suppression of overseas trade, which has caused a large amount of income to flow into the hands of officials and merchants; In desperation, the only way to fill the gap was to increase taxes, which in turn forced the people at the bottom to rebel...... In this way, the cycle of evil surnames was formed, and finally it ended up in the current mess.

Moreover, the political struggle of the Ming Dynasty has also continued to all levels, and the provinces in the south of the Yangtze River are relatively rich, which is recognized by everyone, but in the political struggle, why is the territory controlled by my faction like a big man who is trying to pay out money and materials, while the provinces controlled by your faction are not pulling out a dime...... In this way, everyone is prevaricating to each other in the court, which is nothing more than an extension of the party struggle, they ignore the current predicament faced by the Ming Dynasty, and are only for their own selfish interests......

In the end, by the time the elders in the court hall of the Forbidden City of Yanjing came up with a compromise plan, almost a month had passed, and the result of the compromise was that each of the provinces controlled by the Ming Dynasty had squeezed out a number of silver taels and various materials needed for the roll call, and bought back the 2,000 Xia-style rifles and surplus ammunition that had not been delivered in the previous transaction. At the same time, 300,000 rounds of ammunition and 2,000 quick guns were added to strengthen the armament...... As for the explosive-throwing weapons mentioned by Zhong Shuqing and other Guangxi officials, there are also very good artillery...... Although the Ming Dynasty also wanted to purchase this kind of weapon, it really didn't have the money, and second, it was ...... People don't sell it either!!

The initiators of these things that happened in the north only learned about it after a while, and now the mountain villages are more concerned about the military operations that began this year and the incorporation of new land, and there are many local officials of all sizes in this land of Qingyuan Prefecture, and they have been entrenched for a long time, in addition to the simple conquest by force, it also needs to be supplemented by the pacification of the people's livelihood and the refutation of rumors and the suppression of those remnants by thunderous means, and the garrisons and police guards and administrative staff sent out by the mountain villages are already very experienced, so don't worry too much.

The military operation is due to the fact that it is flowering on three sides, especially the battle line in the east is slightly longer, and it is the first time that the front-line commander reads the command of the first operation (the distance was short before, and the information transmission did not take too long, and even Deng Shifeng could sit in command of the troops), coupled with the fact that the heavy firepower is limited by transportation, the high-level of the mountain village can attract a lot of attention every time they receive a carrier pigeon briefing from the front line.

At present, the information transmission method used by the army in the mountain village is still relatively primitive, and it still uses carrier pigeons to transmit short reports and manpower transmission. Pigeons are fast but brief, and they are easily intercepted and attacked by birds of prey such as falcons. Although manual teleportation is relatively safe, the transmission speed is greatly reduced, and once it is necessary to cross an area such as an enemy-occupied area, it is easy to be intercepted and leak secrets.

As a traverser, I am naturally very aware of the important role played by information transmission in the course of the war, but among all the materials and equipment that cross, there are car radios, stereos, and even refrigerators in high-end cars, but there is no such thing as a radio handset. Of course, the transmission distance of these things is also limited, and even if they exist, they can only be used in small-scale operations in the past, but now once they reach the outside combat far from the base...... It is more reliable to honestly develop tube radio stations......

In the Liucheng County Industrial Park, with the construction of the park, the scale here is not only getting bigger and bigger, but also many factories have begun to put into production, such as the shipyard managed by Zhao Laosi as early as the Chinese New Year to make two experimental warships launched, and the supporting sawmill is also in the rumbling machinery at a jaw-dropping speed to cut pieces of wood and planks for the factories needed.

Considering that Liucheng County has not been under rule for a long time, the mass base and educational foundation here are not as good as those in the mountain villages, and in addition, the development of the army and the expansion of industry have not waited for anyone, and the vast majority of the workers working here are still skilled workers who have been directly transferred from the mountain villages, and the local situation can only be engaged in low-tech and low-paid jobs at present.

Today, however, the protagonist is not the growing number of factories or the workers in the various production positions, but the power from the power plant in a room with long metal poles and wires in the heart of the industrial area, where the electricity from the power shop is transmitted through wires that are still in small quantities.

Abundant electricity is transmitted to the room through long wires, which are used by a cabinet-sized device placed in the center of the room. The device has a tin casing, but there are a lot of shutter-like heat vents in the casing, and inside the iron cabinet, there are several fans that are constantly whining, sending a large amount of cold air inward to cool down some glass bile ducts inside.

"Let's get started!"

Looking at the watch hands on his wrist when he walked to 9:57 in the morning, Deng Shifeng nodded to the female ** worker who was sitting on the table with a huge headset.

As if she had already made an appointment, not long after the ** staff turned on the equipment, at ten o'clock, the small lamp in front of her began to flicker, and in her soundproof headphones, there was also a ticking sound with a regular length.

A few minutes later, when the lamp no longer flashed, there was no longer a ticking sound in the headphones, the staff skillfully replied to a received short signal, and the first real applicable radio wave in this era was transmitted.

"Call: Members of the Radio Application Research Group of the Physics Department, send this message to the headquarters of the Education Center, and say hello to the commander-in-chief and the members of the test team in the Liucheng County Industrial Park!"

This message is not long or short, plus the punctuation mark is exactly fifty characters, although it has been rehearsed many times, and even in the mountain village, this **worker has done many wired telegraph tests and short-distance radio communication of several hundred meters, but when she put together the decoded text and read it to her teacher and other people in the room, her voice still couldn't help but tremble, and she paused three times in the middle of the forty-seven word sentence because of excitement.

In fact, not only her, but also several members of the research group who came to install and debug the equipment are also very excited, after so many years of hard work, the epoch-making physical research of radio has finally changed from a short-distance small experiment of 10 meters and 100 meters in the laboratory to the practical application of the two radio transmitters separated by more than 40 kilometers.

On behalf of all the members of the mountain village, I would like to express my heartfelt congratulations to the members of the Radio Application Research Group of the Physics Section, and look forward to your persistent efforts to achieve radio miniaturization and mass production and application as soon as possible!"

The content of Deng Shifeng's reply made the scene burst into applause, and in the education center more than 40 kilometers away, the research group that received the reply was again cheering...... Radio research, after several years of hard work, finally got the initial results.

Deng Shifeng's research on radio actually started quite early, but at that time, there were very few people who could receive middle and higher education, and because of production safety, they mainly focused on smelting, chemistry and mechanical processing, and there were almost no students interested in physics, and Deng Shifeng couldn't do so much research alone, so radio research has always been something on paper.

With the development of the production capacity and the overall level of research in mountain villages, as well as the gradual expansion of the number of personnel receiving primary and secondary education, and the increasing number of students receiving advanced education, radio research began to appear on paper in specialized research working groups.

It has been exactly three years since the birth of the first electron tube as thick as an arm in the laboratory, during which thousands of electron tubes used for various experiments have been repeatedly trial-produced and applied research, providing the research group with a large amount of practical application data, from a single calorific value to power consumption to the use effect and service life, a large number of first-hand data to determine the most suitable for different power tube products under the current production technology.

This kind of repeated observation of the surname of the study consumes a lot of time and research costs, but it is a process that this kind of product must go through, to put it mildly, just how thick the thickness of a tube glass shell to do has been repeatedly tested and studied, thicker to increase weight and reduce heat dissipation capacity, too thin and fragile to be put into practical application, Deng Shifeng is a traverser, yes, but even if the traversal is a tube research expert- He also has to honestly produce products according to the production capacity and practical application requirements under realistic conditions!!

Today's wireless telegraph is still very immature, not only huge in size, but also in terms of power consumption and calorific power, it cannot really be used in the army, but as my teacher said, with the development of technology and the progress in the research and production of electronic tubes, it will not take a few years for the army to use the era of knapsack wireless telegraphs.
