Grandpa traveled through the Republic of China, and I shocked the world!

"If you like it, I will sell it to you at the original price, which is only 50,000 yuan, and give you 5 crossbow arrows as a gift."Li Dayou smiled very meaningfully.

Zhao Dezhu was so shocked that he couldn't close his mouth. He confirmed with his eyes that it was something he couldn't afford.

"Uh, excuse me."

After that, he bowed to the expensive crossbow, turned around and ran away. Now that he has money in hand, he can start to increase grandpa's firepower.

He ordered 100 large gasoline barrels from the Internet,

200 Bags of potassium sulfate compound fertilizer, and a ton of white sugar.

Gasoline barrels are used to make"heartless cannons". The method is also very simple. Zhao Dezhu directly printed a production tutorial from the Internet.

Mix potassium sulfate and white sugar and it can be made. After obtaining the high explosive, it is no less powerful than TNT, but it requires refining potassium sulfate from chemical fertilizers.

The method and proportions are also found on the Internet. When the time comes, just send them together.

In this way, the shortcomings of insufficient firepower can be After getting a certain amount of supplements, you can pay attention to their use.

The next step is to prepare for the Eighth Route Army to make its own weapons.

Zhao Dezhu has thought carefully about it recently. With the current industrial level of the Eighth Route Army, it is not realistic to make guns.

It does not mean that It can't be made, but the performance, quality, and output are definitely not as good as those of the Little Devils.

The most important thing is the bullet. The Eighth Route Army cannot make bullets by itself. Even though a bullet is inconspicuous, the technical content inside is not low at all.

Bullets are divided into Three parts: warhead, barrel, and primer.

Warheads are divided into armor and bullet cores. Ordinary bullets are usually copper-cased lead cores or steel cores. The barrel body is formed by stamping multiple times from a copper sheet.

It not only needs to be tightened The mouth of the shell needs to be drilled with a fire hole at the bottom and the bottom edge of the shell.

The primer is the most inconspicuous, but its importance is undoubted. If there is something wrong with it, the gun will not fire.

None of these processes Nothing can be sloppy, it is all precision work.

Even in modern society, there are many countries in the world that can produce guns and artillery. As long as they are countries with modern chemical industry capabilities, they can produce them, but there are only a few countries in the world that can produce bullets (copper bullets). There are less than 30 countries in the world that can produce both bullets and artillery shells (copper artillery shells). There are currently only 13 countries in the world.

Even the third brother, who owns an aircraft carrier, still needs to import its artillery shells and bullets.

The current industrial level of the Eighth Route Army is different from It is far less practical to make guns and bullets than to make mortars.

First of all, the mechanism of a mortar is simple, consisting of a gun body, a base and a bracket.

Secondly, it is large enough and easy to process, even if there is no machinery. The equipment can be processed with a file.

The most important thing is that the artillery shells are easy to make and can be poured with molten iron. At most, there are few fragments, not uniform enough, and the lethality is a little bit low. But will the Eighth Route Army dislike it?

Not to mention that you have yourself. Well, I found the detailed data of the Type 31 60mm mortar.

This was a mortar that could be manufactured domestically during the Anti-Japanese War.

The barrel was 677mm long and was forged from low carbon steel.

The Burma Highway was closed. Later, steel plate coil welding was used to make the gun barrel, and the rest of the structure was made of aluminum alloy. The strength dropped directly by one level, but the weight was also much lighter, which was still acceptable.

And I didn’t need to go to so much trouble, just follow the I bought one ton of high-carbon steel seamless steel pipes, and ordered the breech cap, pestle and firing pin to be customized by three manufacturers.

After being sent over and assembled, it was a complete gun body, and the base was okay and could buffer the bracket. After searching online for a long time, I couldn't find anything that can be done.

If you can't find it, it won't be troublesome. It doesn't mean that it can't be used without a bracket. Let the grandfathers of the Eighth Route Army figure out their own solutions.

The last and most important thing is to purchase the materials for making cannonballs.

Cannonballs can be made from gray iron.

You can just buy scrap materials. Anyway, they need to be recast in the furnace.

The total cost of buying all these was just over 10,000 yuan.

High-carbon steel pipes cost more than 6,000 yuan per ton, gray iron scraps only cost 2,200 yuan per ton, and other items only cost more than 2,000 yuan per ton. It is not too cheap.

After placing the order, he discovered that the address was his own home, and there were tons of stuff that couldn't be accommodated at home.

So he rented a small yard in the suburbs, waited for the items to be delivered, and piled them in the yard. A junkyard.

Regardless of that, dial Grandpa’s phone number quickly. You will definitely give him a big surprise!

But reality slapped him in the face again.

Zhao Jianguo simply didn't have that many energy points to transport more than three tons of materials.

"Grandpa, your golden finger is so useless that you can’t even transport such a small amount of things!"Zhao Dezhu said dissatisfied.

He had carefully prepared the big surprise for so many days, but in the end he couldn't deliver it.

"You kid is already disgusted with it, but you haven’t yet!"Zhao Jianguo replied unconvinced, and after thinking for a while he said:"Let me give you 50 energy points first, and leave 10 points for emergency use."

"50 energy points is 500kg. What do you want to do to get there?"
