The reason why Yulin is known as the Pearl of the Fortress is similar to that of the neighboring city of Jiangnan. Although it is located on a plateau, it has a flat terrain, dense water network, numerous lakes and wetlands, hundreds of miles of fertile fields, and a total cultivated land area of hundreds of thousands of acres.
There are 53 large and small rivers, and the water resource reserve is second only to the 800-mile Qinchuan River.
In the Ming Dynasty, Yansui Town, one of the most important towns in the world, relied on Hengshan Mountain to defend against the invasion of tribes from the Mongolian grasslands. Since ancient times, this place has been an important place in the north. Yulin City, which is rich in natural resources and water resources, is like a pearl embedded in the Loess Plateau.
The northernmost part is shining and dazzling.
In terms of prosperity alone, Yulin is even more prosperous than Yancheng, ranking first among local counties in Shaanxi Province and second only to the capital Xi'an.
Nowadays, Yulin is the main grain-producing area in the base area, with more than 40% of the grain supplied by Yulin District.
"What are the organizational arrangements after arriving in Yulin?" Yu Hua admired the northwest desert shrouded in twilight. Although he could not see the beautiful scene of the lonely smoke in the desert, the endless flat grassland was still spectacular. After a while, he returned
After coming to his senses, he turned to look at Lu Junyu.
"The commander arranged to go to the headquarters of the 1st Red Division to rest." Lu Junyu replied.
"The First Red Division..."
Yu Hua nodded, thinking silently about this legendary unit.
The First Red Division originated in Jinggangshan. The instructors personally built the framework. After its formation, it was brave and tenacious, not afraid of hardships and dangers, and made many achievements. The most famous battle was the forced crossing of the Dadu River.
After going through the Eastern Expedition and the Western Expedition, the First Red Division became famous in the north. The command team was composed of "One Chen and Three Yang". One Chen was Chen Kang, the current head of the Military Industry Bureau, and the three Yangs were Yang Wu, Yang Zhi,
Yang Yong, three fierce tiger generals
This is Chen Kang’s basic market.
The 1st Red Division headquarters is stationed in Lantian Village, east of Yulin City. The village's name comes from Lantian County in Guanzhong in ancient times, about five or six kilometers away.
The Dodge truck drove steadily and accelerated slightly.
Thanks to the construction during the Ming and Qing dynasties, the road conditions around Yulin City are better and can carry trucks. There are both former official roads and rammed earth roads built subsequently. The roads are hard and spacious, far better than those in Yanyu when they came.
highway.
Yu Hua felt the road conditions in Yulin City through the bumpiness of the Dodge truck. He couldn't help but nodded secretly. It was indeed right to choose Yulin as the steel plant. The current road conditions alone saved a lot of manpower, material resources and time.
Using these ancient official roads and rammed earth roads as the roadbed, you only need to lay a layer of concrete on top, without having to worry about building a roadbed.
"Comrade Lu, do you know where this place is?" At this moment, Yu Hua suddenly saw a flat area, probably south of Yulin City, with two rivers meandering around it, covering an area of about five or six square kilometers.
.
"That's called Sancha Bay, the intersection of Yuxi River and two other rivers." Lu Junyu looked in the direction pointed by Yu Hua, identified it carefully, and responded.
"Sancha Bay..."
Yu Hua silently wrote down this place.
Along the way, he observed and recorded the roads and environmental information south of Yulin City. Soon, the Dodge truck carrying everyone arrived at Lantian Village in the east and arrived at the division headquarters. Later, Yu Hua met Yang Wu, who was known for his bravery and skill in combat.
"Deputy Leader Yu, on behalf of all the officers and soldiers of the First Red Division, I welcome your arrival. I am a rough man and don't know how to speak. During your inspection mission, the 5,800 people in the First Red Division will listen to your instructions. If there is any problem,
No matter how much you ask, I, Yang Wu, will definitely satisfy you. I will offer you a cup of tea instead of wine." In the division headquarters meeting room, kerosene lamps emitted dim yellow light. Yang Wu and three division headquarters staff members stood in a military posture, holding cups in their hands.
Express your stance to Yu Hua.
"Thank you, Comrade Yang. I don't have any instructions. I will conduct a comprehensive inspection of Yulin in the next week and need a guide. Come on, it's an emergency. I'll drink again when I have the chance." Yu Hua nodded and smiled, picked up the cup, and brought it to his mouth.
Drink it all.
Yang Wu and several staff officers nodded and smiled when they saw this. They all took a gulp and drank tea instead of wine to express their respect.
Others did not know Yu Hua's identity, but Yang Wu and the division staff present knew that the organization was planning to build a steel plant in Yulin, and Yu Hua was the technical expert sent by the organization to inspect the plant site.
In the telegram sent by the old chief Chen Kang, there was a lot of information about Yu Hua and the steel plant. The Red Division must fully cooperate with Yu Hua, meet any requirements, and must protect Yu Hua's safety.
This is a dead order!
After drinking, the two sides met and had a brief chat. Yu Hua was then arranged to rest in a house in the division headquarters. Lu Junyu and three headquarters guards stood at the door, and four other people from Hongyi stood outside the yard.
Soldiers from the division headquarters guard battalion.
With Yu Hua's arrival, the entire division's alert intensity was raised to the highest level.
Some things are not afraid of ten thousand, but just in case. No one can guarantee that Yulin will be 100% free from enemy prying eyes.
After a peaceful night, Yu Hua, who was tired from traveling and traveling, slept comfortably and felt extremely peaceful. It must be said that eight Red Army veterans were on guard duty. This kind of treatment is not something that everyone can have.
…
The next day.
In the distance, the sky is white with fish belly, and it is already dawn.
The sky is covered with dark clouds and the mountains are as majestic and thick as mountains, exuding a depressing atmosphere.
It looks like a heavy rain is about to hit.
"Chief, the weather is bad today. It's likely to rain heavily. Should we go out?" Lu Junyu entered the house with a basin of hot water, opened the door curtain, came to the earthen bed, and said to Yu Hua, who was getting dressed.
"How long will this rainstorm last?" Yu Hua frowned. It was about to rain heavily as soon as we arrived in Yulin. This was the unfavorable rhythm of God.
"According to comrade of the First Red Division, this heavy rain may last for two days. It often rains for days in Yulin, and it is more common in summer." Lu Junyu replied.
"Two days? If I can accept two hours, Comrade Lu, pack up and we'll set off immediately." Hearing this, Yu Hua shook his head repeatedly. Two days was too long and he couldn't wait any longer.
"Yes, then I will prepare more raincoats and supplies." Lu Junyu heard Yu Hua's answer and could only nod and obey.
After saying that, he turned around and left.
"I hope I can find the best location within a week." Yu Hua thought silently in his heart, washed his face and brushed his teeth with hot water, and then continued to pack his belongings.
Although the steel plant was determined to be located in Yulin after a meeting of the highest department of the Military Industry Bureau, this did not mean that all places in Yulin were suitable for building steel plants. Yu Hua had to choose a best location as a starting point.
Soon after, the expedition team was ready to go, carrying dry food, a change of clothes, and rain shelter supplies. There were six people in total. In addition to the five Yu Hua, there was also a soldier from the First Red Division who served as a guide.
When you are in a deserted place, a guide who is familiar with the location and conditions is essential.
At the entrance of the division, six war horses stood. Yang Wu and three staff officers who had seen him last night were seen off. They couldn't resist Yu Hua who insisted on setting off, so they had to give up.
"Deputy Team Leader Yu, I wish you success in finding the place that satisfies you." Yang Wu sent his blessing.
"Thank you, expedition team, let's go!"
Yu Hua held the saddle tightly with both hands, stepped on the stirrups, and sat on the horse's back with an unskilled and unfamiliar posture. He rode the most docile horse in the division and gave instructions to everyone in the expedition team.
The inspection route was rugged and complicated, and traveling by car was far less convenient than riding a horse. As a last resort, Yu Hua had no choice but to learn to ride a horse.
Fortunately, the horse beneath him was extremely docile and obedient. Even if Yu Hua was a novice who was trying to ride a horse for the first time, she would not resist if she occasionally made some wrong moves.
Well, yes, the horse is a girl.
The expedition team galloped with six horses, leaving the division headquarters and traveling in the northeast direction.
"Send power to the headquarters. Target No. 6 has set off." Yang Wu and three staff officers raised their right hands in military salute. After Yu Hua and his party gradually moved away, they immediately ordered.
The communications staff officer immediately nodded, turned and left.
As a large energy consumer, a steel plant needs to be near water, close to raw material supply, flat terrain, and convenient transportation. Yu Hua hopes to find a place in the direction of Shenmu from Yulin that meets the above conditions as a factory site.
If not, then you can only choose Sancha Bay.
The group of people left Lantian Village and came to the outside world. At this time, a scene of busy highway construction came into view.
Thousands of soldiers and workers belonging to the 1st Red Division used sledgehammers and pickaxes to pound the large pieces of gravel dumped on the ground, turning them into fine pieces, which were then loaded and transported by wheelbarrows to the
In a special place, another team of soldiers is responsible for mixing the gravel and soil evenly and laying it on the preset road area of 12 meters wide.
The entire construction process has a strict division of labor, clear organization, strict compliance with standards, and construction with almost the highest human efficiency.
This is the construction of a gravel soil roadbed in preparation for the future laying of concrete cement pavement.
There is no mechanical equipment, no engineering vehicles, no familiar breaker hammers and stone crushers, everything is done by hands.
There are five more Red Army construction teams like this, which are heading to various preset road sections between Yulin and Shenmu. Multiple sections are being constructed at the same time. In addition, several cement and mud kilns are also under construction.
And this highway is the Yushen Highway that was determined after a meeting and discussion.
Looking at the construction scene of Yushen Highway, these soldiers started working before dawn, sweating like rain all over their bodies, Yu Hua smiled: "Come on."
"Boom!" A loud booming sound pierced the dark sky and resounded throughout Yulin City.
storm!
The storm is coming!
"Drive!" Yu Hua took a deep breath, shouted, and gave instructions to the docile horse beneath him, and his running speed picked up again.
Lightning flashed in the sky with great force. After a while, the storm that had been brewing for a long time poured down. Countless dense raindrops the size of pearls cut through the sky and watered this northern land.
Six war horses marched against the heavy rain.
Come on, come on for a new future, let the storm come more violently!
When Yu Hua set out to inspect the factory site, the equipment, materials and supplies for the oxygen top-blown converter project in Yancheng, except for the air separation equipment and oxygen lances, were transported to Yulin.
…
In the blink of an eye, two days have passed.
Linfen Railway Station.
"Squeak!" A sharp and harsh sound of metal friction came out, and the entire freight train loaded with goods slowly entered the station and stopped at the unloading area.
"It's finally here, let the comrades unload the goods as quickly as possible." On the train, Luo He, who personally escorted the goods, breathed a sigh of relief when he looked at the familiar appearance of Linfen Railway Station.
After four days and three nights of running around, the freight train departing from Tianjin Wei Port, carrying more than 200 tons of German-made mechanical processing equipment, finally passed through the Pingjin war zone and was delayed for a while at Zhengding, Shimen.
, and finally arrived in Linfen safely.
But it's not over yet!
Only when it is truly transported to the base area can it be considered safe.
Next, we need to open the wooden boxes and transport the metal parts one by one to Matou Pass by land transportation, across the Yellow River, and directly to Yancheng.
After the train came to a steady stop, members of the organization disguised as workers in the unloading area stepped forward one after another and began to disassemble the goods according to the predetermined plan, carefully loading and transporting precision parts one after another.
When the German-made mechanical processing equipment arrived in Linfen for transfer, some changes had already taken place in Yancheng Liushugou Industrial Zone. In just a few days, the arsenal organized workers to train and learn manual custom-loaded ammunition production technology, and had successfully trained three batches of workers.
The professor used lathes, electric furnace steel and gray pig iron to build a number of serious human-powered lathes.
The pedal-type transmission structure connects the flywheel through the crank, and then amplifies the torque through the gear set, successfully allowing the spindle to reach the speed of turning the steel core. Due to design problems, this human lathe requires three people to operate, one person does the turning process, and the other two people
Acts as a powertrain.
After basic performance testing, the main performance of the human lathe fully met the standards, and mass production and use were immediately started. In the war years, everything was so fast.
Based on the reloading bullet workshop, Liushugou Arsenal was renovated and expanded into the first phase of the fixed-loading ammunition production workshop. A total of four human-powered lathes were put into use, and the daily output of fixed-loading ammunition reached 750 rounds.
The entire first-phase fixed-loading ammunition production workshop can accommodate twenty human lathes. Based on the maximum daily output of 300 rounds per machine, the designed daily output of fixed-loading ammunition is as high as 6,000 rounds. The planned daily output of the second-phase project is as high as 12,000 rounds. The third-phase project
The planning target is to produce 20,000 pieces per day.
Of course, neither the second phase nor the third phase will be achieved in the near future.
The manual loading of ammunition is on the right track. In addition, the hand-operated small ball mill and two-roller cross-rolling machine inspired by Yu Hua were completed after Professor Zhuang worked day and night to manufacture them.
The principle of the ball mill is very simple. A drum is similar to a cement mixing barrel. Hundreds of metal balls are added inside. Small pieces of ore are fed into the drum and rotate in a circle. The height of the metal balls rises and finally falls, crushing and grinding the small pieces of ore.
Finally, the ore powder is obtained.
Generally speaking, ball mills are driven by electric or diesel engines. This condition is not available in the base area, so we choose to add a set of gear transmission ratios to amplify the torque and drive them manually.
The entire small ball mill can be equipped with five people at the lowest level and eight people at the upper level. The grinding time and grinding efficiency are determined manually.
To be honest, if this kind of machine were placed in future generations, the person who developed this machine would definitely be scolded as a capitalist and a coward Super Plus.
A total of two prototype hand-operated small ball mills are assembled at Liushugou Iron Works. The iron ore grinding efficiency and output are two orders of magnitude higher than the efficiency of sledge hammers. They are widely praised by Liushugou mining warriors.
The sixteen soldiers who controlled the two ball mills became heroes in the eyes of the soldiers and were called the Sixteen Warriors.
The pressure was immediately placed on the mining team. There was no other way. After equipped with a ball mill, the grinding efficiency of sixteen people was much higher than that of a mining team of hundreds of people.
In order to mine enough iron ore for smelting, the soldiers of the mining team hammered harder.
