Bright Sword: Starting from the Improved Grenade

"The bullets currently used by our army are mainly 7.92x57mm Mauser rifle bullets provided by the Nationalist government, and 6.5x50mm Arisaka rifle bullets captured from the Japanese army."

In the office, Zhao Tianyang stood in front of the blackboard, writing the data of bullets currently used by our army, with Mr. Liu and others sitting below.

Ever since the Taihang Type 60 rifle and Taihang mortar were completed, they came to Zhao Tianyang to ask for tasks again, so this meeting took place.

"But as the number of our troops increased, Chiang Kai-shek did not increase the amount of ammunition."

"If we want to seize the Japanese army's ammunition, we must destroy the Japanese army in an organized manner and ensure that the Japanese army has not used up all its bullets."

"Especially since our army is still mainly engaged in guerrilla warfare, with more small battles than big ones, the problem of lack of ammunition is something we have to consider."

"Forget about getting ammunition from outside. I don't think Chiang Kai-shek would want to see that. There are only two options left for us. One is to reload the ammunition, and the other is to make our own bullets."

"Given the current conditions of the arsenal, it is entirely feasible to make your own bullets. As for reloading bullets, we must also pay attention to it."

At this time, Mr. Liu spoke.

"Ah."

Zhao Tianyang nodded and continued, "A bullet is divided into four parts: the warhead, the shell, the gunpowder, and the primer."

"With the current technical reserves of the arsenal, we can quickly make our own bullets by simply combining them. However, for the sake of efficiency, we need not only a manual bullet reloading machine, but also a semi-automatic bullet production line."

After saying that, Zhao Tianyang glanced at everyone and began to assign tasks directly: "Comrade Liu Guifu is responsible for the research and development of bullets and the bullet reloading machine. Is there any problem?"

"Row."

Liu Guifu nodded in agreement.

"Comrade Shen Hong and Comrade Cheng Mingsheng, are you in charge of the semi-automatic bullet production line? Is there any problem?"

Upon hearing this, Comrade Shen Hong and Cheng Mingsheng looked at each other and nodded: "No problem!"

"Okay, the semi-automatic bullet production line is very difficult. First, we need to solve the power problem, and then the stamping machine and other problems."

"The Arsenal will fully support this matter. If you need anything, just tell Deputy Director Li directly. If there are any technical difficulties, we can hold a meeting to discuss them at any time. Just let me know if you need me."

"With the factory director's words, we feel relieved."

Shen Hong smiled.

"I'll have to trouble Mr. Liu to help coordinate this project."

Finally, Zhao Tianyang looked at Mr. Liu and said.

"it is good."

Mr. Liu smiled faintly.

Soon, a project with a secret level of three, code-named "Re-equipment", and a project with a secret level of two, code-named "Freedom" were quietly launched in the arsenal.

Zhao Tianyang also devoted himself to the development of the two projects, and seven days passed.

Zhao Tianyang did not go to the office that day. He followed Shen Hong and others to draw blueprints. Not only did he not go, he also called Wu Yunduo and Liu Ransheng out of the office.

It's been seven days. It's time to address the penicillin issue.

"Director, what should we do?"

Wu Yunduo and Liu Ransheng, holding tools, looked at Zhao Tianyang with interest.

Although they don't know what they are working on now, based on the level of this project, their interest in it cannot be low.

"Clean up the things on the desk first!"

Zhao Tianyang spoke to the two of them while checking the culture medium.

In order to keep the experiment confidential, he decided to do it in his own room. Fortunately, his room was large and the desk could be used as a workbench if he tidied it up.

After the two of them tidied up the desk, Zhao Tianyang placed a glass bottle on the table, then folded a piece of white paper into a funnel shape, placed it on the mouth of the glass bottle, and then put a piece of cotton on the mouth of the funnel.

"Hold on, I'm about to fall!"

"Director, I've got you covered, pour it!"

Wu Yunduo said nervously, holding the funnel.

Zhao Tianyang carefully poured the culture medium into the glass bottle through the funnel, and then said to Liu Ransheng who was holding the rapeseed oil in his hand.

"Okay, pour the rapeseed oil!"

"Yes."

After pouring three times the amount of rapeseed oil as culture medium into the glass bottle, Zhao Tianyang picked up the chopsticks and began to stir.

He kept stirring until the liquid in the glass bottle was separated into three layers, then stopped.

"stop looking."

Zhao Tianyang interrupted the two people's curious gazes and ordered: "Bring a small spoon and use it to scoop out the top two layers of material in the glass bottle."

"Oh, oh." x2

Soon, the two layers of fat-soluble substances and insoluble substances in the glass bottle were scooped out, leaving only the water-soluble substances at the bottom of the bottle.

"Okay, pour the toner you prepared a few days ago into the glass bottle!"

Zhao Tianyang checked the liquid in the glass bottle, and after making sure there was no problem, he gave instructions to the two of them.

"Yes."

Pour in the carbon powder, and when the carbon powder in the glass bottle has absorbed all the liquid in the bottle, you can use distilled water (water that has undergone distillation and condensation operations is called distilled water) to wash the carbon.

Then add acidic water (acidic water made by diluting sulfuric acid) into the bottle, followed by alkaline water.

(Sodium bicarbonate is obtained by filtering the reaction between soda ash and carbon dioxide, and then 237 mg of sodium bicarbonate is added to 600 ml of water and stirred to obtain alkaline water.

"Of course sodium bicarbonate, you can also call it "baking soda" by its nickname.

After adding the two types of water, filter it again with a cotton funnel, and the resulting liquid is the penicillin solution.

Drop a little penicillin solution into the prepared staphylococcus culture dish and wait for two days. If the dropped penicillin solution repels the staphylococcus and forms a circle, it means that the penicillin solution has been extracted successfully.

(Add an appropriate amount of sugar to distilled water, and then put the staphylococci extracted from the infected skin into it.)

(Of course, the real staphylococcus culture dish may be more rigorous.)

"Okay, today's mission is complete, you can go back."

Zhao Tianyang put the things away, dusted off his hands and said to the two of them.

Two days passed quickly and Zhao Tianyang waved his hands excitedly as he looked at the circle in the petri dish.

With this thing, he can take it to the Soviet Union or the United States to exchange for good things, but the prerequisite is large-scale production. However, given his conditions, it is not impossible, but it is easy to be exposed.

Thinking of this, Zhao Tianyang returned to his desk and began to write down the extraction methods of allicin and penicillin, as well as the precautions. He decided to submit these two things to the central government.

In this way, not only could he get a golden medal of immunity from death, but the large-scale production of allicin and penicillin in Yan'an could also be kept secret.

Moreover, Yan'an has wider channels, so if he wants something, he can just report to them and he doesn't have to worry about it.
