"Ugh!"

As the two were talking, they heard a scream.

When I turned my head, I saw a stout public security officer, holding a red and white striped stick in his hand, and slamming it on a person who fell to the ground.

The guy who danced with his hands on the ground, screaming and holding his head to dodge the stick, looked like a foreman in the coal yard under the "Daqing Petrochemical".

"Daqing Petrochemical" stands out in Mentougou, that is, everything is different from others, and the employees of all its subordinate factories and mines are all uniforms.

According to the rebuke, grade, and type of work, the color of the uniform and the armband are different.

This one alone is unique in Mentougou.

The guy who fell to the ground and covered his head to dodge the stick and howled, gray long-sleeved woolen overalls, wearing a white lacquered rattan helmet, and wearing a "one" bar on his shoulder, Chu Laosan had more dealings with "Daqing Petrochemical", and at a glance he knew that this represented an open-air operation field, a material pipe, and a first-class foreman.

In the coal yard, the foreman can shout at the "coal blacks", and if he is not satisfied, he will beat and scold, but in front of the "public security", like a lamb to be slaughtered, he will be beaten and rolled all over the ground with a few sticks.

"What's wrong with that man?" Junko was surprised by the scene in front of her.

"Don't line up, cut in line."

Chu Laosan has seen a lot of such scenes, and said disapprerovitically, "The ninth master uses the military to rule the factory, thinking that he can cut the queue if he leaves the factory?" Whoever let him wear overalls deserves to be beaten! Fortunately, it was the public security that ran into it, and if you ran into the chengguan, you had to pay a fine. ”

"Chengguan?" Wang Laishun was even more surprised.

"yes."

Chu Laosan is saying, "In ancient times, there were Jinyi guards, and now there is a city management team, and when you come to Mentougou for a long time, you will know." ”

As he was talking, he saw that there were acquaintances among the few people who walked by in front of him, so he hurriedly raised his hand to greet, "Master Ma, Master Ma." ”

“… Wow, third. ”

Ma Baozi, who was walking forward with the apprentice pulling the cart with his hands behind his back, turned his head when he heard the sound and saw the person who greeted him, bared his teeth and was happy, and stopped and raised his hand in response.

"Why is Master Ma going?"

Chu Laosan pulled a straight, and hurriedly walked over to Ma Baozi.

"Peel the sheep and send it to the canteen."

Ma Baozi pointed to the skinned sheep and two deer stacked on the apprentice's cart, "As a result, two more deer were sent, and I was about to find land to peel them, and Xiaozao was in a hurry." ”

"Is Mr. Sun here?"

Chu Laosan didn't dare to delay Ma Baozi's business, and asked directly.

"It's not in the number."

Ma Baozi searched for a moment and replied, "You go to the Shijian Coal Yard to have a look, oh yes, you go first... Register a waist card in the line, you can't get in without a card. ”

“… Waist card? ”

Chu Laosan was stunned when he heard this, and for a moment he was so happy that he blurted out, "The ninth master is here?" ”

"Ingenuity."

Ma Baozi looked at Chu Laosan and smiled, "However, I didn't say anything." ”

After that, he smiled again, waved his hand to the little apprentice who pulled the cart, and continued to find land to slaughter deer.

……

When Chu Laosan and Wang Laishun followed the flow of people rubbing shoulders and squeezed into the Mentougou branch of the Daqing Construction Bank, they saw that there were criss-crossing ropes hanging in the hall, and countless clips with bills were "swishing" on the rope.

More than 20 pen stickers who buried themselves in writing behind the counters on the east and west sides of the north, Mr. Bookkeeper, from time to time, put a piece of freshly written bills, clamped them with a clip, hung them on the string on the head, and then pushed hard, and the bill clip was on the heads of the guests, and slid to another counter in an instant.

Save time, effort, and road, it is the same as the Pansi Cave in the hall, which is not like the silver horn at all.

“… The semi-annual coal bills delivered in the autumn of the seventh year of Kangxi were one or six cents per premium. ”

A middle-aged man in the uniform of a bank supervisor rushed in from outside the door, waved his hand at the pen sticker behind the counter on three sides and shouted, "Stop issuing tickets, stop issuing tickets." ”

"Coax!"

As soon as the words came out, many businessmen dressed in the lobby shouted and scolded, and immediately rushed over to surround the middle-aged people, and many people held up the orders that had just been opened and were just waiting for payment, asking him to give an explanation.

"What is this?"

Chu Laosan looked at the chaotic bank lobby with a puzzled face......

……

"Woo, woo, woo!"

In the Shijian Coal Yard, a faint whistle came from the direction of the adjacent Shijian Coal Mine.

It was a whistle dedicated to reporting the time of the mine, and it sounded once every hour.

The land is being leveled in the field, and the ragged coal workers are wearing dirty braids and sweaty headscarves, and many people are reluctant to wear the over-the-waist slit cotton knicks that are distributed, and they are still wearing the original homespun thick coats, old sheepskin jackets, and cotton clothes and shoulders.

"Cotton" is different from "cotton", the former is vegetable cotton, and the latter is filled with animal hair such as wool.

Many people wear fleece sheepskin jackets, and more are filled with cloth and other scraps in the homespun cloth, just to keep warm from the wind, rotten clothes and fat crotch pants, patches and patches, and kicking straw shoes under their feet without exception.

A group of coolies working in the surrounding mines are lifting stones with pickaxes, shoveling and shoveling soil, and the stones and soil are piled up in baskets, and when the two baskets are full, they will be picked up and carried away with a flat pole.

When encountering a boulder, it will be tied with a thick hemp rope, and one or two people will carry the rope in front, bow in front of the body, and shout like a slender man and drag it away.

The construction site is divided into separate and mutually subordinate operation areas and sections by small colored flags planted on the ground one by one.

One by one, the overseers with the word "supervisor" armband on their arms, waving small flags of various colors, with whistles around their necks and sticks in their hands, kept wandering around the operation areas they were responsible for, and from time to time a few terrible whistles sounded.

Each overseer carried a large cloth bag containing a wooden chip and a dyeing pen, and every time the coolie carried the burden, he would throw a blue wooden chip the length of his index finger into the basket, and every half an hour he would issue a red wooden chip to the laborer who wielded the pickaxe.

There are also unlucky overseers who draw a cross on the door of their heads with a dye pen, and then they are driven out of the workplace by the inspector wearing the word "patrol" armband.

The special pigment is difficult to wash off for a few days, and if you have this sign on the brain, you will be stopped outside the venue, and you will come back to work after a few days.

The encouragement of fundraising, the supervision of the whistle stick, the threat of cross-cutting heads, the coolies in the operation site are full of motivation, sweating like rain, and from time to time shouting a collective trumpet and laughing.

Coolies are not only gentlemen, many of them are also women, most of them are mothers-in-law of coal blacks, all of them are thin and short, carrying dozens of pounds of mud baskets and flat burdens, but they are walking like flying, and their small bodies seem to be pregnant with infinite strength.

There are also child laborers with boys and girls, carrying a pile of kettles and towels back and forth on the construction site.

Child labor is not paid, but it can be mixed with two meals and take a hot bath for no money. If the overseer likes it, he can also get a towel, and the grass carp loach and yellow eel that he touches are also willing to be accepted by the kitchen at the construction site.

In the yards where soil and stone are piled up in the north and south of the construction site, there are manpower flat screen trays, vertical screen buckets, and mule grinders, and the fine soil and gravel screened out will be picked up by the flat pole back into the rope line supported by wooden poles for backfilling.

On the left and right of the rope, a lever device like a trebuchet, kowtowing up and down, a rectangular stone mill tied at one end, was driven by a mule to be lifted with a winch at the other end of the lever, and then a person waved a wooden hammer, a hammer smashed down the machine, and every time it fell heavily, it tamped the loose soil for a minute.

On the rammed roadbed that extends to the west, neat wooden sections are being placed horizontally on the ground by people on the left and right with picks at a distance of six roots per zhang.

There are five feet of movable wooden segments on each side, which are across the sleeper, which is the standard spacing, and the spacing is different.

The two ends of the sleeper are drilled with holes two fingers wide, and the civil engineer in charge of riveting takes out the pointed thick wooden nails with the length of a small arm from the basket, inserts them into the wooden eye, and then swings the stone hammer to ram the wooden hole and drill deep into the ground to fix the sleeper.

The magic modification of the traditional Chinese carpentry riveting wedge!

Yuanji can't afford to use so much iron at the moment, and the loads of horse-drawn trains can be carried by wooden tracks, and even the nails of the sleepers are made of wooden nails.

Hard and simple, self-reliant, all imperialism is a paper tiger, there are no railroad trains, and "railways" are still built from trees!

Although in Yuanji's view, the "railway" he built is really earthy, but in Mentougou in this era, this is a miracle!

Horse-drawn carts pulling coal to run on wooden rails? Spread fifty miles to the outskirts of Beijing and pave it into the mine? At first, the people in the surrounding mines thought that the "Ninth Master" was crazy!

In the early Mentougou, mules were used in the mountains and camels in the flats. Horse-drawn trains? I haven't heard of it, where is the fire?

On the rows of sleepers, there are two wooden rails covered with thin iron sheets, and the recesses between the sleepers have been filled with small crushed sand and cement, and the sleepers in the rails have been leveled with the ground, so that horses can run without hurting their hooves.

Looking west, the track extends all the way to the depths of Mentougou, and there is no end in sight.

The track is not straight, but slightly winding, and can be climbed, following the hilly lowlands and valley mouths, and extending all the way according to the relatively low terrain.

On the track that has been paved in the west, rectangular carriages with a pulley pressed on the track are being trotted and pulled by two healthy horses, transporting the materials and daily necessities needed by the construction site.

In the direction of the valley mouth to the east, dense villains are clearing the vegetation of the valley mouth, raising rocks and leveling the ground for leveling a passage that can be used for the track to pass.

From time to time, in the depths of the Mentougou hills, there will be a few dull echoes, which are the movement of experimenting with the explosives of the mountain.

China has long had explosives for opening mountains, and Japan has them, mainly to attack the city, one is to hang on the city gate to detonate the city gate, which is called "fire dragon attack". One is to dig tunnels under the city wall and use it to blow up the city wall, which is called "earth dragon attack".

Tunnel siege, one type is a siege tunnel supported by wood, and then the wood is burned, destroying the supporting structure of the city foundation and allowing the city wall to collapse on its own.

The other type is to put explosives directly in the tunnel under the city wall, and collapse the city wall in sections after detonation, Yang Xiuqing of the Taiping Heavenly Kingdom is the master of the explosive version of "Earth Dragon Attack".

For the people, it may be magical, and for Manchurian military aristocrats like Yuan Ji, it is something that must be learned.

It's just that the current gunpowder ratio is unstable, and Yuanji's chemistry is not good, only the dye will explode and other general common sense.

He also did not know what the chemical synthesis formula and industrial production method of TNT were, the synthesis process of catalysts and decomposition steps, and the materials that should be used in reactors and other containers.

Glassware is corrosion-resistant, but that's lab-grade synthesis, industrial-grade large-scale preparation, and it's impossible to use glass test tubes.

Laboratory production and industrial production are two processes, and in the absence of basic materials science, we can only establish a systematic material comparative test system while experimenting and groping blindly.

At present, even the ratio of yellow explosives and nitrocellulose is unstable, and the sealing and detonation methods cannot be determined.

It was too dangerous to study explosives, and the storehouse where the yellow dye was stacked exploded without an open flame. I don't know if it was lit by the sun or if the dust exploded.

What should be the humidity for storage and transportation, and should it be ventilated or sealed? There is no comparative experiment, lack of testing conditions and basis for formulating standards, it is all taken for granted, and it is fried as it is said.

There were so many bad things in the preparation, storage and transportation of explosives that even he couldn't figure out what was going on. The test could only be carried out in the barren mountains and mountains first, and it was studied in the name of explosives.

When there is an opportunity, we will be able to build a system of colleges and universities in primary, junior and senior high schools, cultivate a base of science and engineering talents, establish a targeted weapons test site and a sample collection and data analysis system, and lay down a modern arms industry at the same time.

As soon as the flower of war blooms, there will be market demand, and internal production, education, and research will be connected with external demand, and military science and technology will take off at an accelerated pace.

"Master, don't suffer the cold."

Beside the ditch parallel to the road outside the yard, a group of guard-colored people gathered around Yuanji, walking along the ditch, patrolling the double-track carriageway that was being laid.

A twenty-year-old feminine student with clear eyebrows, holding a snow-white mink fur coat with a fur collar, walked slowly to Yuan Ji's side, bowed down, and said softly, "The slave put it on for the master?" ”
