The Triangular Thorn is a mythical weapon.

In that war decades later, the Triangular Thorn did play a great role in white-knuckle warfare, inflicting great casualties on the enemy.

So in the legend, the lethality of the Triangular Army Thorn is infinitely magnified, such as how many centimeters into the body will surely die, such as the sashimi contains drama, such as being listed as one of the prohibited armaments by the world organization, and so on......

But almost all of this is false news.

At that time, the equipment of military spurs was the same as the dilemma that Zhang Ran was currently facing - that is, the quality of high-quality steel was not up to standard, and the bayonets produced could not be carried on the battlefield, and the use of three-edged military spurs was completely a last resort.

The use of three-edged design can indeed greatly enhance the hardness of the military thorn and make up for the shortcomings of the lack of material hardness, but it loses the function of tool cutting, chopping and so on......

It can be said that the replacement of the bayonet by the triangular military stab has obvious shortcomings.

However, under special conditions, the triangular military thorn is also a relatively qualified substitute.

Moreover, in the current era, antibiotics such as penicillin have not yet appeared, and the diamond-shaped wound caused by the triangular structure will greatly increase the chance of infection for the enemy......

Under the combined force of various circumstances, Zhang Ran finally decided to let Niu Da build a three-edged army stab instead of a bayonet.

There are two types of Mitsubishi military spurs, one is a spiked cone type and the other is a T-shaped chisel type.

Zhang Ran chose the T-shaped chisel as the equipment of the detachment.

The reason for choosing the T-shaped chisel is also due to the fact that the quality of the steel is not up to par, and the tip of the taper is easy to break, while the T-shaped chisel is thicker and not easy to break.

Of course, there are also T-shaped chisel tips that are slightly cut on both sides after grinding, and in white-knuckle battles, in addition to stabbing and stabbing, you can also perform simple bayonet tactical movements.

After teaching Niu Da the specific structure and size of the general's thorn, Zhang Ran gave up.

Watching the cow tinkling in the blacksmith shop, banging, pinching his chin and shaking his hand as the shopkeeper, Zhang Ran had a strange feeling - that guy who is called a horse and a cloud is just a visionary to command a large group of tech-savvy people to become the richest man?

He suddenly realized that he was a little like the horse or something.

A sense of superiority in strategizing and winning thousands of miles away made Zhang Ran feel a little fluttering, and suddenly felt that he was so forced.

Lu Yan brought a sample of a set of military uniforms and shoes and handed it to Zhang Ran to see.

Compared with the regular eight-way eight-way eight-master gray military uniform, these clothes are a little more sky gray.

It's not that Zhang Ran doesn't want to make a regular Eighth Master Gray military uniform, the key is that the whole province was searched for at that time, and the closest fabric to Eighth Master Gray was this one.

And the new cloth looks slightly blue, but Zhang Ran believes that after washing a few waters, the clothes will be decolored and old, and they should be closer to the clothes of Balu.

The fine stitches, the material is quite thick and firm, Zhang Ran cocked his thumb fiercely.

"What I'm looking for is made by the best women who are based on the local female red, these clothes not only fit and look good, but also absolutely durable!"

Seeing that Zhang Ran was satisfied, Lu Yan said with some joy.

"It's no problem to do it by hand, but the crotch of these pants still needs to be wider!"

Zhang Ran pointed to his pants and said.

He doesn't want the soldiers to be cold in the crotch when they encounter the enemy and crack their crotch after a few tactical moves.

Other than that, there is nothing special to pay attention to in the pants and military caps.

His gaze fell on the shoe.

According to Zhang Ran's original proposal, these shoes are no longer traditional round-mouth cloth shoes, but high-top cloth shoes with laces, which are worn on the feet and blend with the feet, which are not only comfortable enough, but also used to run.

It's a pity that due to the limitations of materials, in addition to the style, these shoes are still cloth shoes, and the soles are mille-feuille soles with dense twine.

Such cloth shoes are no problem to wear and wear, but if you run for a long time, the wear and tear of the shoes is a big problem.

And it's even more troublesome when it rains or something like that.

It implements military combat, and rubber shoes are the most suitable to wear on the body, which is lighter than the leather boots of the little devils, waterproof and close to the feet than cloth shoes, and more resistant to wear.

But in the current era, galoshes are a luxury.

Not to mention Zhang Ran's poor and white base, even the elite of the little devils don't have the money to put on rubber shoes one by one, and wearing leather boots is already the extreme.

Even the deep-pocketed Yankees had to wear rubber shoes for several more years.

"That's it this time, step up production, and strive to make military uniforms and shoes within ten days!"

Zhang Ran thought about this, sighed and said: "You and Secretary Wang, pay attention to the base area and the surrounding area, see if there are any skins or anything like that, help collect some, and add some leather to the bottom layer of the sole when you accept the sole in the future, so that the shoes are not only wear-resistant, but also somewhat waterproof......"

Lu Yan nodded, indicating that he had written it down.

As soon as Lu Yan left, Wang Changtian came and told Zhang Ran bad news.

In the surrounding area, there is no place to produce coal mines for the time being, let alone the high-quality coal that Zhang Ran wants that can be coking!

Zhang Ran began to pull his hair again, that worry!

There is no coal mine, but it is not only a problem that the copper mine cannot be started, and the plan to develop sulfuric acid cannot be implemented!

In fact, coal is too useful for the base area!

The coke after coking is not only a high-quality fuel that can be supplied to the copper smelter, but also the flue gas produced during coking can also be recovered!

The recovered coal tar separates gasoline, diesel, and two important chemicals – benzene and naphthalene!

These two things can also be synthesized into high explosives!

In this era, no matter what kind of explosives, nitrification or otherwise, there is no need to worry about running out of them, only the problem of not being enough!

Although the explosives synthesized by phenylnaphthalene are poisonous or have other disadvantages, they are not many times stronger than the black powder made by Mao Drill, isn't it?

"Damn, Lao Tzu just wants to make some weapons, so why do you have to start an industrial chain from scratch in the end - do you have to find your own way to dig coal?"

Zhang Ran was depressed, but he didn't have any choice, so he could only say to Wang Lao: "I'll find a way to deal with the coal mine, you can find some coal first, and let the copper mine start work first!" ”

"If you buy loose coal, the cost will be huge...... Wang Changtian was awe-inspiring.

"There's no way to do it, let's talk about it first, and when I come back from going to Lingjiang Fortress, I'll go to build a coal mine for the base area!" Zhang Ran said.

Wang Changtian glared at Niu Da when he heard this: "Captain, do you know where there is a coal mine?" How do you know? ”

“……”

How could Zhang Ran tell him that in a few decades, the country will be full of mineral exploration teams, and no matter where there are mineral deposits, they will not be able to escape the eyes of the geological team.

Do you know what mines are there, what's so strange?

However, he was in pain when he thought that the Longwanggou Coal Mine in the next county was hundreds of miles away from the base area, and that it was difficult to bury the coal mine deeply......

But what's the solution?

Dongjiang County, where the base is located, has never heard of coal anywhere!

After arranging everything that should be arranged, Zhang Ran finally had time to focus all his energy on the training of the team......
