Xiaozhu is wearing a big one, and the Qima under it is short and narrow, how awkward it looks - no way, then Gaoli is Amani's old clothes, so it looks big, and Qima was bought by Abbaji for Xiaozhu during the Spring Festival three years ago, of course, it is small. (Crab note: Gorly is the short blouse in Korean women's clothing, and Qima is a long skirt; Abbaji is the father, and Amani is the mother)

Xiaozhu is 12 years old this year, even if she is malnourished, she still jumps quickly, and Qima three years ago is now dressed almost to her knees.

Her body is very thin, and against the background of the big dung pocket that straddles her waist, it shows her thinness.

With a bamboo tong in her right hand, she tossed through the long grass from time to time, searching for horse and cow dung—horse manure that could be composted, and cow dung, in addition to making a fire, could be used to stick to her family's leaky fence walls.

Her surname is Zhao - this is a relatively rare surname in North Korea - Xiaozhu is just a nickname, she actually has no real name, of course she doesn't need it, just call her nickname before she gets married, and after she gets married, she should be called "a certain Zhao", just like her aunt is called "Zhao Jinshi".

Her family is the herdsman slave of Liu Yuhou, and Abbaji and her two elder brothers take care of a herd of more than 40 horses and more than 10 cattle for Liu Yuhou.

It's just a little hard, the key is that no matter how hard and tired you are, the family never seems to be able to eat!

Not only did she not have enough to eat, but she also owed Liu Yuhou a debt - the livestock that had frozen to death and starved to death over the years, Liu Yuhou could have all been recorded on her family!

So even at a young age, Xiaozhu is very sensible and does her best to contribute to the family, for example, picking up horse manure.

In late autumn, the grasslands have begun to wither and turn yellow. The lower half is still dark green, but the upper half has turned gray and yellow, and when the wind blows, it makes a "Sala Sala" grinding sound; The occasional bushes in the prairie had also withered, and the yellow leaves were blown high into the air by the wind.

Thanks to the eyesight she has cultivated by picking up horse manure on a daily basis, Xiaozhu soon noticed that there were three bushes not far away that looked a little strange - the yellow-green grass was mixed with many black dots.

Is there a lot of horse manure there?

She rushed over. The dung pocket slammed into her waist as she ran.

Suddenly, she stopped, her eyes widened, her mouth wide open enough to put down a pigeon egg, and the bamboo clip in her hand fell silently - the three bushes of "grass" actually stood up!

Xiao Zhu, who was stupid, looked straight at one of the "grasses" and stretched out an arm, and there was a little cold light on the arm!

After standing for a while, the "grass" finally put away the cold light, and quietly turned around to chase the other two "grasses" that had already left.

Until the three clumps of "grass" disappeared from the sight of the beads. Xiao Zhu then felt that her soul had returned to her body, and let out a sharp scream.

"Hell~~!"

——————————————————————————————————————————————————————————

At the same time that Xiaozhu screamed, at the foot of Nanshan Mountain, more than twenty miles away from her, two heavy stone troughs were erected and inserted into a stone platform.

The stone trough is 1 decimeter wide and 3 decimeters deep; After the stone trough was erected, a 1 decimeter thick cast iron plate was inserted into the stone trough, and in the center of the upper edge of the cast iron plate was a cutting edge up to 10 centimeters wide - it is not accurate to say that it was a cutting edge. To be exact, it is a protrusion with a large angle of obtuse cross-section. However, on this protrusion, Wang Denghai forged a lot of blade steel.

After installing this iron plate, Wang Denghai lifted another iron plate and inserted it, the upper iron plate was exactly the same as the lower one, the difference was that its blade was facing downward.

After a soft sound of "Boom". The two iron plates are tightly fitted, and there is a small hole with a diameter of 4 cm between the upper and lower cutting edges.

After installing it, Wang Denghai nodded at Chu Fan on the side and said, "Childe." This one...... Pull...... The drawing device is ready! ”

After Chu Fan stepped forward to inspect it, he asked Lao Zhao Tou and them to bring the five cows up—these five cows were bought to plow those experimental fields.

After setting the yoke, Chu Fan personally measured and adjusted the length of the ropes of the five cows, and tied all the ropes to an iron sleeve with a latch, and then turned his head and ordered Wang Denghaidao, "Master Wang, you can bring the soft steel rod." ”

Wang Denghai answered, and brought a soft steel rod with a diameter of 8 centimeters and a length of 50 centimeters from the side - that is, a wrought iron rod mixed with a small amount of pig iron.

After bringing it, Wang Denghai inserted the soft steel rod into the stove that had already been lit, burned it until the steel rod was red, and then used the joint efforts of other craftsmen to lift the steel rod between the upper and lower iron plates, and fixed the steel rod with the bolt on the iron sleeve.

Then Wang Denghai and another craftsman climbed onto the high wooden frames on both sides of the stone platform, raised a sledgehammer and began to rhythmically smash an iron plate on it.

As the sparks splashed around, the two iron plates gradually approached, and finally came together.

Regardless of the heat, Chu Fan leaned in to check it, and after confirming that the iron plate was completely closed, he nodded at Lao Zhao, who shouted, "Drive!" The leather whip in his hand was loudly whipped on the cow's buttocks.

The five cows mooed and struggled for a while, and the straightened rope finally began to move.

In the tooth-sore "sizzle" sound, the reddish soft steel rod was dragged and moved slowly, and finally changed from an 8 cm steel rod to a 4 cm steel rod!

Chu Fan, who had been staring at him, couldn't help but clench his fists and exhaled softly, "Oh yes!" The first step of the drawing process has been completed!

The subsequent process can be carried out step by step - 4 cm and then 2 cm into 2 cm, 2 cm and then 5 mm, and the wire is done.

That's right! The way Chu Fan thought of restraining the cavalry was barbed wire!

The serpentine barbed wire proved to be a good barrier in World War II, and the key is that it is extremely easy to arrange - a few wooden stakes are inserted, and the barbed wire fence is hung up, or it is too late, and it can be done without wooden stakes!

Before the cavalry rushed into battle, two or three serpentine barbed wire fences 4-5 meters high were arranged in front of the Fuliao army, and it only took a few minutes to completely restrain the cavalry's charge - of course, the spikes on the barbed wire were indispensable!

The use of the serpentine barbed wire fence does not stop there, because it is extremely convenient to arrange and clean up, it will also greatly reduce the labor intensity of the camp of the Fuliao army!

The most troublesome part of marching in this era is camping. When the march reaches the beginning of the afternoon, that is, after three o'clock, it is time to stop and camp - cutting down trees, digging trenches, erecting walls, erecting lookouts, and setting up fights...... There are so many things that you can't do it in four or five hours!

Therefore, it is understandable that the speed of marching in this era is only a few dozen miles a day - a small half of the time is spent on camping.

It is easy to do with barbed wire - two or three laps around the perimeter of the camp a hundred steps, and bells are hung at intervals, and the warning effect is quite good; The walled wall does not need to be erected, so naturally there is no link of cutting down trees. It can be done in advance, and it can be assembled directly when it arrives at the place.

In this case, the time to set up camp will be compressed to less than 1 hour, which means that the Fuliao army can march until 6 p.m.!

In addition, the Fuliao army has been practicing iron feet, and the marching speed is easy to rush to 100 miles a day, Chu Fan feels that traveling 120 miles a day is the passing line! - You must know that the 24-hour march record of the Workers' and Peasants' Red Army in later generations is 240 miles!

The mobility has come up, and it will be great to take advantage of the battlefield - the victory of the Huaihai Campaign, is not it the iron feet of the two field armies in the Central Plains and East China?

Just when he was immersed in the joy of the successful trial production of barbed wire, he did not expect that a fierce quarrel was breaking out on the beach in the west of Ushishima. (To be continued.) )
