Taking the number of soldiers into consideration the combat effectiveness of the troops, this is a very common phenomenon. Otherwise, how could there be more soldiers and more generals?

Of course, this also has some truth, and cannot be said to be an absolute mistake. However, this method also has disadvantages. The troops with varying quality require a lot of resources, and the elites are mixed with them, so they often cannot receive special care and are easily dragged down by others during battles.

However, from the perspective of the expansion speed, training methods, organization and equipment of the New Seventh Army, there will be different feelings. Although the overall combat power is the goal, Yang Tianfeng also tilts resources to the elite. Taking the special forces as an example, in order to facilitate the disguise of surprise attacks, almost all of them are Japanese weapons, and they are equipped with short guns, forming a double-dressing, neat and majestic.

But unlike most people's ideas and judgments, the special forces are equipped with Japanese equipment for convenience of combat, while the field elites of the New Seventh Army are equipped with all kinds of national equipment. The Czech Republic is made, and the Japanese-slaughter chainsaws are combined, plus the shotgun, grenade launchers, 60, 120 mortars, etc., at least the unified bullets has been achieved, and the logistics support is relatively convenient and powerful.

Of course, it is impossible to standardize all guns. Yang Tianfeng can only be in the battalion and try to unify the caliber of weapons within the regiment. The troops equipped with Japanese equipment can only use two or three types of gun bullets, and they are also equipped with Czech-made and slaughtered chainsaws, which is more troublesome in logistics.

Because of the inability to achieve unifiedness, even military production needs to have different bullet production lines. Mauser bullets, six-five bullets, mullet bullets, and assault rifle bullet production lines under construction. The logistics pressure is obvious. If we had not obtained weapons and ammunition from the war zone, the military department would probably have abandoned other weapons and produced bullets.

In the war, bullets were the most basic materials. Without bullets, guns were better than fire sticks. Yang Tianfeng attached great importance to this and also received help from military technicians in the rear. For example, experts and engineers from Chongqing No. 25 and No. 20 Arsenal were very helpful in the construction of bullet production lines.

Of course, the machine drawings and processes that adapt to the new process and the improvement of enhanced ******* formula provided by Yang Tianfeng not only improves the production technology of the large rear arsenal, but also greatly improves the stability of the gun bullets, and greatly reduces the pollution and ablation of the gun barrel.

The technological progress, coupled with the enthusiasm for work during the War of Resistance Against Japan, the effect was obvious. Chongqing No. 25 Arsenal started production since its relocation in 1939, with an annual output of more than 3,300 bullets; the 20 Arsenal reached more than 54 million, which set the highest output record.

The bullet production volume of Yongcheng Arsenal is also steadily increasing, the process of copper clad steel plate is becoming more and more mature, the expansion of the chemical industry, the continuous self-made and purchase of machinery and equipment, and the recruitment of a large number of workers, including a large number of female workers, provide a foundation for development.

Therefore, when Yang Tianfeng received the intention of the Eighth Route Army to purchase or exchange medical supplies and weapons and ammunition, he did not think too much about it, so he picked up his pen and wrote down the first batch of materials.

Although the Eighth Route Army also had military production and could also produce bullets, it was reinstalled and in very small quantities.

Because of this, the Eighth Route Army lacked ammunition and really had no capital to fight any major battles, and even the policy of resisting the Japanese was unable to do so.

For example, during the Hundred Regiments War, an infantry regiment knocked out 7,000 bullets, was criticized for wasting bullets. Most troops had ammunition on average on each rifle, with only about three rounds. In the middle and late stages of the Anti-Japanese War, if a machine gun had fifty rounds and a rifle twenty rounds, it would be a very elite unit in the Eighth Route Army.

The bullets can still be reloaded, but the shells will not work. It was not until 1942 that the Eighth Route Army Arsenal was able to manufacture mountain artillery shells, and the defective rate was still very high. Of course, the number of seized was very small, so that a brigade commander-level officer was required to obtain approval from a brigade commander-level officer.

Yang Tianfeng not only agreed to exchange medicine and ammunition, but also agreed to credit assistance, generously gave the Eighth Route Army two Jinyuan artillery and a 92 infantry artillery, each artillery was equipped with thirty rounds of ammunition, and sent a twenty-man artillery team to assist in the fight and help train artillery.

Although the Eighth Route Army had long recorded the use of Type 92 infantry artillery, due to the lack of professional artillery talents, ammunition replenishment cannot be guaranteed. Therefore, it is basically used as it is seized, and buried or destroyed after use. The time and number of use are very limited, so naturally there are no major results.

Since they were all anti-Japanese teams and fighting the Japanese, the Eighth Route Army still needed to resist the threat from the north, Yang Tianfeng was naturally not stingy.

What's more, some of the industries in the base area are in the development stage, and some have just been created, such as medicine, civil chemicals, cigarettes, etc., which really requires a stable development environment and a safe development time.

Although the Japanese would not give Yang Tianfeng too much time, the intensity of the war was smaller and the help of friendly forces was more beneficial to the overall development of the base area.

In addition to various industries, there are also various schools to open. Special training classes for officers, artillery, special forces, snipers, engineers, military doctors, and medical nurses. This is directly for the military. Technical schools such as turning workers, fitters, carpenters, and maintenance workers, and industrial workers, including folk workshops.

Until now, a comprehensive base in Yang Tianfeng's mind has been fully constructed. He can be self-sufficient and self-reliant. His goal is not only to open up land and farm, but also to let the people have a meal.

…………

The ancient city of Haozhou.

After excavation and expansion, the Cao Cao army transport road located underground in the old city has expanded to more than 2,000 meters. The machinery and equipment of the diversion arsenal have been installed in the underground and on-ground workshops, and production workers have been recruited and training has begun, and the factory is gradually starting to produce.

Behind the south wall of the city is a steel mill under construction, with direct access to the troop transport road below. There are city walls and troop transport roads to provide protection, which is very safe.

The coal chemical plant is located outside the city and is built on the exit from the troop transport road that extends to the outside of the troop transport road. If necessary, the troop transport road can be used as an air raid shelter. Moreover, the factory is surrounded by woods, providing good concealment and protection.

In addition to migration and diversion, military industry, coal chemical and other industries have also been refined and decomposed according to the process. Some simple productions are stripped out, factories are built separately, and the quantity is increased; complex and advanced deep processing takes stricter protection measures, reducing unnecessary production and improving work efficiency.

In this way, with more rough processing plants, the production of basic materials can be multiplied to meet the ever-increasing manufacturing production level and lay the foundation for the launch of new products.

For example, in the coal chemical plant in Haozhou, there are three crude factories planned to be built, mainly producing coal coke and coal tar. The advanced processing plant plans to build two, one of which is the second factory that has completed most of the construction work in Chengnanxiao District.

Yang Tianfeng leaned in the chair, running around constantly, staying up late to write, design, and thinking carefully. Coupled with this continuous day and night work, he looked quite tired.

"Drink the egg water." Zhao Yurou brought a bowl of freshly brewed egg water, feeling a little distressed, but she didn't want to show a caring look on her face.

Yang Tianfeng took it and sipped slowly, thinking about something, or wandering around, but his eyes were a little stagnant.

Zhao Yurou was silent for a while, and broke the silence without saying a word. "The steam heating reactor was successfully manufactured, and synthetic rubber could be manufactured in large quantities, and the rubber-soled single shoes and cotton shoes you mentioned can be supplied to the army."

Yang Tianfeng's eyes turned, he glanced at Zhao Yurou, pursed the corners of his lips, nodded with a smile, and said, "Yes, this is a good start. In the future, it will be smoother to increase the reactor and increase the output."

It turned out that there was a reactor in the coal chemical plant laboratory, but it was used for chemical experiments or teaching equipment, and large-scale production was definitely not suitable. Therefore, Yang Tianfeng designed a ten-cubic meter steam heating reactor based on the information in his mind, which could complete chemical processes such as polymerization, condensation, vulcanization, hydrocarbonization, and hydrogenation.

Design is relatively easy for Yang Tianfeng, but manufacturing is quite troublesome. It took nearly two months to process the arsenal's machinery and equipment. After being transported to Haoxian, it was assembled and debugged for two days and two nights, and used the relocated machinery and equipment to repair and process the inappropriate parts. Today, the final assembly was completed and the first trial production was carried out.

Although there are still some small problems that need to be solved and improved, they have been considered successful overall. As Yang Tianfeng said, the first step is difficult, but after taking it, it will be smooth and even able to develop like an enclave.

As for the current domestic situation, the impact of the war has caused a shortage of materials and has become increasingly fierce. Not only military supplies, but also civilian supplies are short of everything. On the one hand, Yang Tianfeng wants to use civilians to support military industry, on the other hand, he can resist Japanese light industrial products to facilitate people's lives, and on the other hand, he is to improve the army's equipment.

For example, ethylene-propylene rubber that is about to be manufactured on a large scale is not only advanced (synthesized by Americans in 1955), but also uses two simplest monomers, ethylene and propylene, and the structure is basically the same as natural rubber. Although the catalyst used (also known as Ziegler-Natta catalyst) polymerizes isoprene, it is relatively complicated, but the amount is small, which is extremely beneficial for large-scale production.

Not to mention the manufacturing of large rubber products such as tires, the soldiers did not have rubber shoes or raincoats, which made Yang Tianfeng a little unacceptable.
