Bright Sword: Starting from the Improved Grenade

At 11 o'clock in the evening, the New Year's Day dinner came to an end.

Li Yuncai scratched his head with a wry smile. How could these people eat so much?

Not only did he eat up all the prepared meat, vegetables, and flour, he also ate more than 30 kilograms of corn paste.

"Alright! Just eat it."

Zhao Tianyang came over and patted Li Yuncai on the shoulder: "After eating so many delicious foods today, the employees will work harder tomorrow to repay us."

Zhao Tianyang was right. One should be grateful for what one has received. After the dinner tonight, the efficiency of the arsenal has been significantly improved.

Even the regularization project, which had always had some bumps in the road, was being carried out more smoothly.

I believe that in another week, the assembly line working mode will also appear in the arsenal.

"It's very simple to imitate Judison's explosives. All you need is nitroglycerin, saltpeter powder that has had its crystal water removed, and a small amount of rice bran."

The next day, at the rocket factory, Zhao Tianyang stood in front of a blackboard, holding a piece of chalk in his hand (don't ask where the chalk came from, Li Yunlong stole it from the Japanese), and gave scientific explanations to the two people in front of him.

"Director, we all know nitroglycerin and bran, but what is saltpeter powder without crystal water?"

Li Mutou raised his hand and asked, holding a small notebook.

"Yes, we know about saltpeter, but what does it mean to remove the water of crystallization?"

Blacksmith Wang also echoed.

“Water of crystallization is present in crystals and is also known as water of hydration.”

Zhao Tianyang paused and continued, "Crystallized water is water molecules bound in compounds. They are not liquid water."

"Many crystals contain water of crystallization, and in some cases, the amount of water in a substance is the total amount of water at a certain temperature."

"And most of them exist in a certain stoichiometric ratio. When the solute crystallizes from the solution, a certain number of water molecules are combined in the crystal. Such water molecules are called crystallization water."

After listening to Zhao Tianyang's explanation of what crystal water is, Li Wang the blacksmith and Li Mutou looked at each other. It's not that they didn't understand, but they didn't understand it at all.

Zhao Tianyang felt a little headache when he saw this. As expected, even if he forced them to explain, they wouldn't understand.

"Well, forget it. You just need to understand that removing the crystal water means completely removing the water in the saltpeter."

"Hey, Director, why didn't you tell me earlier? I understand now."

Li Mutou suddenly realized: "Isn't it the same as dealing with the saltpeter in black powder? Boil it over high heat to completely remove the water in the saltpeter."

"Yes, that's the same."

Zhao Tianyang nodded: "Since you understand, then this time the task of imitating Judy's explosives will be handed over to you two."

"No problem, Director, just wait and see."

Li Mutou patted his chest and assured.

"Director, Master Liu is looking for you."

Just then, Liu Zaisheng came over in a hurry.

"Do you know anything?"

Zhao Tianyang asked.

"Wen Dao, Mr. Liu and his team have already drawn up the design drawings for the rifle and mortar. I want you to go and take a look."

Liu Zaisheng nodded and replied.

"You guys keep busy. I won't help you this time. If you succeed, I will give you a mysterious gift."

Zhao Tianyang looked at Li Mutou and Wang the blacksmith, gave them some instructions, and followed Liu Zaisheng out of the gunpowder factory.

"Great, we will do a good job."

Li Mutou and Wang the Blacksmith were both looking forward to the mysterious gift that Zhao Tianyang mentioned.

The arsenal conference room was built with fresh wood and exuded a faint woody fragrance, which gave Zhao Tianyang, who had just opened the door and walked in, a startle.

"Brother Tianyang is here, come and see how our design is?"

When Master Liu saw Zhao Tianyang coming in, he quickly pulled him to the blackboard, on which the data of the two weapons were drawn with chalk.

"This rifle is based on the Czech carbine. Without affecting the performance of the gun, some simplified changes have been made based on the combat characteristics of the Eighth Route Army."

"It weighs only 6.72 kilograms and is less than one meter long, 100 to 200 millimeters shorter than an ordinary rifle. The caliber is 7.92."

"This sight in particular can adjust the shooting deviation, which is very friendly to novices. It was designed by Comrade Liu Guifu and his team."

Liu Guifu scratched his head embarrassedly: "It's all thanks to the comrades. The bayonet of this rifle was designed by Comrade Liu Ding himself."

"It is usually folded under the gun body and closed with a button, so you can throw the bayonet out at will when fighting."

"And the three-edged design will cause the person stabbed to bleed profusely. It can be said to be extremely brutal."

"Type 81 Cavalry Rifle."

After listening to the two people's descriptions, this idea immediately popped up in Zhao Tianyang's mind.

Unexpectedly, after his changes, Liu Guifu and others still designed this rifle. However, in order to prove his guess, Zhao Tianyang still asked tentatively.

"The data is perfect. What material do you want to use?"

"Railroad steel, walnut."

Master Liu said without hesitation that these two things were almost readily available to them, the Eighth Route Army.

Moreover, Zhao Tianyang has already used rail steel to make cannons and grenade launchers, which shows that rail steel is a very high-quality steel.

“That’s no problem, but how do we rifle the rifle? Our arsenal doesn’t have a rifling machine. This is one of the reasons why Zhao Tianyang hasn’t manufactured rifles yet.

“Rifling is done by cold extrusion.”

Liu Guifu continued.

After a few questions and answers, Zhao Tianyang was almost certain that this was the Type 81 Cavalry Rifle. However, the Type 81 Cavalry Rifle was indeed very excellent. Now that it had appeared, he had no way to stop it.

"It's a very powerful rifle. The manufacturing method is simple and the materials can be found everywhere. Let's make a sample gun and see how it goes."

Zhao Tianyang smiled.

"Great."

The experts involved in the development of the Type 81 cavalry rifle shook their fists vigorously.

"The following is the mortar, which imitates the French 60mm mortar..."

There is nothing much to say about the mortar. This type of low-pressure artillery, with the blast furnace, Master Liu and his men don't need to look for train axles to drill the barrel.

As long as all the data are designed well, it is very easy to make a 60mm mortar.

After casually listening to the data, Zhao Tianyang nodded and asked them to build one first to see.

After agreeing with Master Liu and his team to make a weapon first, Zhao Tianyang was fine. Liu Guifu and his team would be responsible for the specific work. Zhao Tianyang found Shen Hong, who was leading people to manually clean a lathe.

"Master Hong, I heard that you have connections in Shanghai. Can you bring back some teaching materials?"

"Textbook?"

Shen Hong put down the polished parts in his hand and looked at him puzzledly: "What teaching materials?"

"Mathematics, physics and chemistry, preferably from high to low."

"This isn't difficult, but it's a bit expensive to ship from Shanghai. Why don't you find Master Liu and ask him to get you a few sets nearby?"

Shen Hong suggested.

"Yes, but there is chaos in Shanxi right now. Schools can't open anymore. Do we still have textbooks?"

"Don't worry, textbooks are precious things. You can definitely find them if you look for them."

After hearing this, Zhao Tianyang ran to find Mr. Liu again and told him about his problem.

"You are preparing to be trained as a senior technician!"

Mr. Liu saw through Zhao Tianyang's idea at a glance, and immediately patted his chest and assured him, "This is a good thing. Leave the teaching materials to me."
