The night was getting darker, but the preparation rooms inside and outside the laboratory were brightly lit, and the staff were busy preparing for the preparation of medicines.

The special medicine for malignant fever is sodium antimony gluconate, the main raw materials are antimony and sodium gluconate, and the secondary materials include chlorine, sodium hydroxide, hydrogen peroxide, and methanol.

Yang Tianfeng was confident that he would prepare medicine overnight, not only the production process he found in his mind, but also the two main raw materials he took from the arsenal.

China is a major producer of tungsten ore and antimony ore. Both of these minerals have strategic value and are important raw materials for military production. Needless to say, tungsten is made of alloys made of antimony, lead and tin can be used to improve the performance of welding materials, bullets and bearings. It is also one of the minerals designated by Yang Tianfeng to purchase from the rear.

If the steel surface needs to be chrome, tin and nickel plating to suit special uses, the surface of the steel billet needs to be strictly cleaned to make the coating firmly combine with the steel surface. Sodium gluconate is usually added to the cleaning agent to achieve the ideal effect.

Although sodium gluconate was not produced in China at that time, the process was not complicated, and the fermentation method was mainly time-consuming. The simplest production method was to use substances containing glucose (such as grains) as raw materials, and use fermentation method to first produce gluconic acid from glucose, and then neutralize it with sodium hydroxide to obtain sodium gluconate.

"These sodium gluconate was bought from Hong Kong, and the amount was not large. I originally wanted to use it as a sample to provide various indicators for production and manufacturing reference. But it is still enough to prepare a small amount of medicine." Yang Tianfeng pondered for a moment and said, "In the future, the laboratory will produce it by itself, and the process flow will be taken out soon."

Professor Hao is convinced that the laboratory already has a lot of information provided by Yang Tianfeng, and the personnel and equipment are constantly expanding. He feels sincere pride and pride in the ability to be at the forefront of the country, can fill the gaps in the country, and can save the lives of thousands of people in the country, and has the enthusiasm for work that is impatient.

Yang Tianfeng said orally and Hao Jiaqi recorded that the process of producing antimony sodium gluconate formed textual materials. Professor Hao and others read the information and discussed the key links with Yang Tianfeng. Then they put on protection and entered the laboratory to work.

Although Yang Tianfeng did not directly participate in the preparation of medicine due to his right arm injury, he was not idle either. Recently, he has been busy with command, war, production conditions of arsenals and aircraft manufacturing departments need to be reported, and he has accumulated a lot of problems that he needs to provide guidance and solve.

It’s not that these problems will always exist without Yang Tianfeng, but that time does not wait for anyone. Yang Tianfeng’s knowledge and methods can solve problems in the fastest and simplest way and speed up the pace of production and manufacturing.

Another bullet production line has been added, and another one is being made in the fu County so that the troops can equip more chainsaws to equip the guns and ammunition drawn from the First War Zone, the third longitudinal showed no sign of a shortage of ammunition.

Of course, this is relatively speaking. Compared with the Japanese individuals carrying 120 bullets, the third column could not even reach half. However, during the War of Resistance Against Japan, the National Army's bullets were equipped with 30 bullets, while the Eighth Route Army's bullets were equipped with only 3 to 5 bullets.

In fact, the simplest and most basic amount of ammunition depends on the overall national strength. To put it bluntly, it depends on the country's production level. Before the war began, China was not an industrial country at all, and war can best test whether a country's industrial foundation is solid.

The number of bullets can also be seen as the difference in firepower strength or the length of continuous combat in some respects.

Because of the limitations of ammunition production capacity and the current troops are still expanding, although the production capacity of the arsenal is increasing, the ammunition pressure for replacing automatic weapons is still huge. Therefore, Yang Tianfeng has not taken out drawings and information for semi-automatic and automatic weapons.

Yang Tianfeng's requirement for the arsenal is to fully produce weapons and ammunition that the troops are equipped with, and to use excess production capacity to develop new weapons. The problems encountered by the arsenal are mainly concentrated in the two items of recoil-free cannons and rockets.

The resilient gun is small in size, light in weight, simple in structure and convenient in operation. It is similar to a steel fist or a rocket launcher, but its range and power are far greater than that of a steel fist.

Yang Tianfeng wanted to manufacture recoilless cannons mainly based on two considerations.

First of all, it is the "cage" policy to deal with Tada Jun, and it has the ability to destroy the Japanese artillery towers and bunkers. Although infantry artillery and steel fists also have this effect, one is slightly larger and the other is too close to the range, which is not the most ideal weapon.

The second is to enhance the power to attack Japanese armored targets. The range of the steel fist is only more than 100 meters, and it often requires the protection of terrain, buildings, etc. Especially in positional battles, the steel fist is very passive against tank guns and machine guns. If there is a recoilless cannon, the distance of direct armor-breaking bullets can exceed 500 meters, and the maximum range can reach more than 6,000 meters if it is a curved kill grenade.

It is flexible, powerful, long range, and relatively easy to manufacture. The technical level of the arsenal can basically meet the needs of production and manufacturing. This is Yang Tianfeng's comprehensive analysis and judgment. Although difficulties are now occurring, they are not unsolvable.

"...The key to the problem is the symmetrical exhaust holes on the edge of the blasting latch. The axis direction of the exhaust hole should be the same as the rotation direction of the rifle. When the gunpowder gas is sprayed from the exhaust hole, the torque generated must be just enough to offset the torque generated by the rotation of the shell on the rifle. Only when it is fired can it offset the recoil force and prevent the gun body from rotating..."

Yang Tianfeng wrote the guidance with his left hand, looked at the somewhat crooked words, and couldn't help but smile and shook his head. It's really not used to changing handwriting!

The footsteps sounded behind him, and Yang Tianfeng didn't care. The laboratory's alert level was very high, and his guards were added outside, so strangers couldn't get in at all.

However, when the person who came passed by him and walked around the table, Yang Tianfeng was still a little surprised after seeing who it was.

Zhao Yuqing! The expression on her face was very serious, although it was not very consistent with her age and experience.

Yang Tianfeng was stunned for a moment and returned to normal. He watched Xiao Bazao pull over the chair, sit opposite him, staring at him.

"How is the special medicine being made? They won't let me in." Zhao Yuqing asked with a little stiffness.
