The brigade commander was slightly shocked when he heard Huang He's words, but after experiencing strong winds and waves, he immediately reacted and said:

"It's great that you think so, although I've met people who are happy to share, but more of them hide their knowledge."

"If you have time, you can write a detailed plan, and I will report to the headquarters about the establishment of the school, and first talk about how you plan to arrange the smokeless gunpowder."

Huang He's eyes looked out the window, and he seemed to see the hard-working comrades through many obstacles.

"First of all, I need some personnel transfers, and many of the comrades in the military factory of our logistics department who are now responsible for reloading bullets are good at black powder."

"They are all veterans who have worked for several years, and they have original experience and a certain foundation for learning new skills, so they can get started relatively quickly."

After thinking about it, he continued to say to the brigade commander:

"I also need a batch of comrades who manufacture grenades in military factories, and in the process of making smokeless gunpowder, I can also try to teach them how to make yellow explosives."

Hearing that another new term appeared, and it was explosives, Li Yunlong became interested again.

"Director Huang, what is this yellow explosive, it's the first time we've heard this thing in so many years of fighting."

Hearing Li Yunlong's question, Zhang Wanhe took the initiative to explain to Li Yunlong:

"You Li Yunlong don't always dislike the poor power of the grenades made in our border area, it's not as good as the melon grenades of the little devils, and you keep saying that the quality is poor, and you still came to me today to ask for me."

"The quality is problematic because the grenades made in our border area are still charged with black powder."

"Although the things left by our ancestors are good, the times are constantly changing, and technology is constantly improving. We have long been behind, and if we fall behind, we will be beaten. ”

When Li Yunlong heard Zhang Wanhe's words, he remembered that when he ambushed the little devils, the soldiers of the first battalion threw grenades at the place where the Japanese must pass.

As a result, the fighters threw grenades everywhere, but few exploded.

The reason was that there was a rain the other day, which damped the gunpowder inside the grenade.

Moreover, the grenades made in the border area often have only two halves of one explosion, and in many cases they cannot achieve the desired effect of offensive grenades.

Seeing Zhang Wanhe exposing his shortcomings again, Li Yunlong scratched the back of his head with a smile and said:

"Hey, hey, look at what your old Zhang said, what can pull out pus is a good plaster."

"The old sleeves are all weapons of the Qing Dynasty, and they are all historical objects made in Hanyang."

"Although our soldiers will dislike it, anyone who can spray bullets will do it, and it is a good weapon to be able to fight devils."

Referring to the grenade, the brigade commander glared at Li Yunlong again, and then said to the Yellow River:

"I'll arrange for you in three days, but I hope you can get smokeless gunpowder and yellow explosives sooner."

"For our Eighth Route Army, grenades and bullets are really too important."

The brigade commander stood up from the kang and walked towards the door with his clothes straightened, and the three of them also got up to send off the brigade commander.

After walking out of the house, the brigade commander pointed at Li Yunlong with a whip and said.

"Li Yunlong, you come with me. A trip to the 772nd Regiment and the Independent Regiment, I will go and see the distribution of weapons and the morale of the soldiers of these two regiments. ”

"The next time you kid comes to the logistics department so blatantly to ask for a weapon, I'll break your legs!"

"He also said that the logistics department is a landlord's old wealth, and as soon as the Yellow River came, he got a large number of materials for our Eighth Route Army to make cotton clothes, and brought back so many Mosin Nagant."

"The division commander said that next time there is a replenishment of weapons, priority will be given to our brigade."

Li Yunlong showed his big white teeth and waved at Zhang Wanhe and the Yellow River, and behind him were the pillars and tigers holding the wine.

"Hey, hey, I know that our brigade commander is distressed, and he thinks about our Xiao Li with any good things."

"Thank you, Director Huang, if you have anything, you can call me Li Yunlong, as long as you don't violate discipline and I can do it, I will definitely do it for you."

"Lao Zhang, let's see you back, I'll take those bottles of wine. The brigade commander said, you can't bribe, hahaha. ”

Huang He and Zhang Wanhe were speechless for a while, this Li Yunlong is really worthy of his reputation and has no skin and no face.

They first said goodbye to the brigade commander, and then said to Li Yunlong in unison: "you, haha." ”

The copper he promised just now is not a matter of lip service.

Although the civilian factories provided by the system are mainly used to trade raw materials for military uniforms, the task will be completed after a while.

After everyone left, Huang He turned on the system and used the trade interface to start checking how much copper the two migrant workers could exchange for.

Two civilian factories can change 25 tons in a month, which is really shocking to him.

——————————————

With his vouching, the five researchers made it to the logistics department without hindrance, and no one doubted their identity.

They began to prepare the materials, after all, it was a matter of prudence to hand over the soil chemical industry to the comrades, and it was necessary to increase the output as much as possible while ensuring safety.

Three busy days have passed.

The comrades promised by the brigade commander were also mobilized from various military factories in the border area and assembled in a larger plant.

Huang He looked at this group of comrades who had been struggling in the arsenal for several years, and constantly sighed in his heart how the environment of this era could be so difficult.

There were young and old, and even one of them was disabled with an arm missing, and the youngest comrade looked to be only sixteen or seventeen years old.

Huang He walked up to them with five people and said:

"Comrades, I am very grateful that you were able to come here from the various military factories in the base area, and the brigade commander should have told you why I brought everyone here."

"You may not know me, my name is Huang He, according to the director of the procurement department that was just established last month."

"The cotton clothes you are wearing now are made of cotton that I brought back. This time we are going to engage in smokeless gunpowder and yellow explosives, which may be dangerous, and even kill people. ”

At this time, the old man with the missing arm came out, and everyone seemed to know him, and he had a great prestige in the crowd.

The old man's accent was very strong, and when he heard it, he was from outside the Guan.

"Director Huang, my name is Jiao Chun, you can call me Lao Jiao. Our family has been craftsmen for generations, and we started to do artillery battles in Shenyang very early, and I would make black powder when I was young. ”

"In 31, the devil called."

"I didn't want to be a slave to the country, my eldest brother and I joined the guerrillas with a family of seven, and at that time we specialized in making black powder grenades for our guerrillas."

"I also know smokeless gunpowder and yellow explosives, and I have even studied them."

Lao Jiao looked at his empty left arm, and continued with tears in his eyes:

"Later, our family came to the base area, and my eldest brother, sister-in-law and my wife were all killed in the explosion accident of making gunpowder."

"My only son was also killed when he touched the waste explosives."

"My two nephews, one died in Pingxingguan and the other died in Guangyang."

"Now that we are in the Jiao family, I am the only one left! Without my family, my home is also occupied, what else is my old Jiao afraid of? ”

Speaking of this, Lao Jiao couldn't control his emotions a little, and slapped his chest tremblingly

"I just want to die with some value, I just want to be buried in Shenyang when I die! Director Huang, don't worry, we people, who haven't ordered the story yet. ”

"Even if everyone dies here, we have to learn from you, as long as we can drive the devil away, we are not afraid of death!"

After Lao Jiao finished saying this, the comrades responded to him enthusiastically, and the youngest child helped the painful Lao Jiao back to the queue.

Huang He held back tears and looked at the imposing comrades, gritted his teeth and said:

"In the future, I will take everyone to study together, we will have what the devils have, and we will also have what they don't!"

He led the group to the podium that had been prepared, and began the lecture with the five researchers.

In order to make smokeless gunpowder, the first step is to make sulfuric acid.

Without this thing, no matter who you are, even if you want to break your head, you can't make smokeless gunpowder, because sulfuric acid is the mother of gunpowder.

There are two main processes for making sulfuric acid in the world.

The first is called the contact method, not to mention the complexity of the device, the important thing is that the fine platinum powder is also needed as a catalyst.

Platinum powder is a bit outrageous, there is not even platinum in the base, where to get powder?

The second method is called the lead chamber method, which is relatively simple.

"I can't write it, this thing is a dangerous chemical that is easy to make explosives, and it is controlled."

A morning passed, and everyone had a certain understanding of the principle of making sulfuric acid, nitric acid, and nitrocellulose.

After lunch, they returned to the factory and began to learn the principles of nitroglycerin and nitrocellulose starch.

Nitrocellulose can be used to make smokeless gunpowder, which effectively avoids the shortage of black powder guns.

At present, the grenades of the military factories in the base area are M24 grenades modeled after Sandezi.

But because of the charge, it is far from the power of the original. It is difficult to produce TNT at the current industrial level of the base area, but switching to nitroglycerin as a charge can greatly increase the power.

As for the use of nitrogenated starch, Huang He intends to use it to imitate the Mark2 grenade of the Ugly Country.

The inside of the MK2 grenade is filled with TNT, but in the early days of the war, TNT was in short supply, and the inside was filled with nitrostarch complex.

The combination of offensive and defensive grenades can greatly increase the combat effectiveness of the troops.

A week has passed, and the comrades have become familiar with the process of soil chemical industry, fortunately there are no accidents.

On November 19, 1939, the Northwest Shanxi Chemical Plant was formally established.

The chemical plant was set up under the leadership of Huang He, director of the Procurement Administration, and the skills were taught and many military personnel were trained, who then provided tons of raw materials to the military factories of the Logistics Department in the base area.
