The handle of the bucket is pointed eastward, and spring returns to the land outside the pass again.

The white ice in Vladivostok harbor was swallowed by green waves, and the rivers were filled with spring water. As soon as the azaleas bloomed on the green meadows, geese and red-crowned cranes flew through the sky in groups, flying over the Sikhot Mountains, and flying towards the Heilongjiang where they had children.

The spring breeze of the rain brought migratory birds back to the north, and also brought the rivers under Beihai Town to a rushing period. The huge and crystal clear ice rows floated with the undercurrents, colliding and roaring. This scene was indeed extremely magnificent for those literati and scholars, but for those villages along the river, it heralds the arrival of disasters.

It is said that the upper reaches of Heilongjiang flow from west to east. After passing Heilongjiang City, it turns to the southeast. After passing Kubutrin, it turns sharply south, which makes this section of the river form a large bow. The middle reaches of Songhua River and Heilongjiang have low latitudes, and the temperature rises quickly first. The upper reaches of Heilongjiang with high latitudes open late, resulting in the formation of a "turning river".

Once those green and hard ices are stuck, they will form ice dams and then squeeze each other to rush up the river bank. Two or three meters high ice will rush around the ground, destroying everything you encounter along the way, trees, rocks, roads, villages, and cultivated land. The most serious consequence of this is that the arable land is destroyed, which makes it impossible to plant grain crops back then, and even the humus soil on the surface will be destroyed, which will take several years to restore the ground force.

Since the start of the "Bohei Railway" five years ago, every time at this time, the Northern Navy stationed in Boli and Heilongjiang City will be ordered to detonate the ice on the key river sections. After the ice period begins, artillery will be dispatched to launch artillery on important river sections that are prone to form ice dams.

Located in an open space two kilometers northwest of Humal Bing Station, six 75mm field guns lined up in a row. Because shelling ice is not a battle, no bunker fortifications were dug.

However, unlike previous years, in another open space 800 meters away on the west side, there was a 105mm howitzer that was different from all the artillery artillery of the North Navy. A chest wall of 1.5 meters high was built with sandbags around the gun position. In addition to six artillery soldiers, there were also several technical personnel of the military-industrial complex on the gun position.

At a hill observation point six hundred meters north of the position, Zhao Liang, wearing a thick military coat, came to the artillery rangefinder and bent down and looked at it for a while, and asked casually: "Are you ready?"

"Report to the head, all shelling parameters have been calculated."

"Where is the ammunition?"

"Twenty ships have been sent."

"It's getting late, prepare for a test shot." Zhao Liang finished speaking, and turned to a technician next to him and sighed: "I've been busy for more than two years, and it's up to today if it's a mule or a horse."

The technician pursed his lips and said, "There is no big problem. More than 300 shots were made on the test site."

"Prepare in one minute!" On the intercom at the gun watch station, the artillery battalion commander issued an order, and then entered the countdown countdown. "…5,4,3,2,1, release!"

Accompanied by a shocking sound, the muzzle of the 105mm howitzer sprayed out flames. The shock wave stirred a large area of ​​smoke and dust behind the cannon, instantly shaking the snow on the ground, revealing the dark land. Immediately, accompanied by the dull explosion, the flames and gun smoke rose up on the thick ice layer on the river surface, splashing water columns dozens of meters high.

"The artillery fires normally!"

"Ballistic normal!"

"Hit the target!" In the temporary gun viewing center, commands were heard one after another. Several technicians recorded various data on the notebook.

Soon, the loader on the 105 howitzer gun position had loaded the second shell, and the gunner quickly adjusted the firing angle and direction of the cannon according to the shooting orders issued by the squad leader. Then there was another loud bang. At the place where the shell fell, a huge piece of ice with an area of ​​more than 5 square meters of area was blown to pieces.

"God! This is too fierce. Comparing our cannons with it, it's all a joke!" On the 75mm cannon's position, several artillery soldiers stuck out their tongues and looked envious.

"If you don't look at the other person's caliber, it's almost as thick as our thighs!"

"I just don't know when this guy will be equipped for us. Ouch!" As soon as the gunner finished speaking, he was kicked hard on the butt. When he looked back, he found that it was the squad leader.

"Boy! I'm so tired of the old and the old? No cannon is as good as our 75 cannons, and they are fast and accurate. I used this cannon back then, and I made the Rakshasa ghost cry and call my parents..."

The artillery squad leader was about to say something again, but he heard an order from the walkie-talkie: "Test-fire 75mm guns and each cannon is tested! One minute to prepare!"

Afterwards, six 75 guns were tested in sequence. Although they were all quite accurate, the shelling effect seen from the naked eye was not a little worse than the 105 mm one. Basically, one shot of 105 and two shots of 75 guns had to be fired to achieve the same effect.

The artillery squad leader who had kicked people spit on the ground, thinking that it was time for me to change the cannon.

After the "Battle of Usolier", the Northern Navy became increasingly prominent in the configuration of artillery, mainly because the 82mm mortar and 75mm gun were not much different in range, and the former had a significantly higher lethality power than the latter, making it more convenient to move.

The maximum range of the 82mm mortar when using No. 6 charge is 4,660 meters, the maximum range of the long-range charge is 5,700 meters, and the maximum range of the 75mm gun is only 6,000 meters. In addition, the maneuverability of the field gun is not as good as that of the mortar, which makes the 75mm gun seem a bit useless.

After all, the purpose of imitating this gun was to get rid of its dependence on the 122 howitzer. At the same time, in order to give the military-industrial complex a try, the model was chosen that was not very difficult to process the barrel and the production of shells was relatively easy.

Over the years, the Navy has been quite satisfied with the 75mm gun. It has a fast firing speed and a small recoil. I am the only one who bullies others, but others cannot bully me.

Since the 122 grenades in Beihai Town are not yet produced, Zhao Xin has to spend a lot of money to purchase every time, so the North Navy urgently needs to develop a heavy artillery for this time and space.

After comparing the data of howitzers of various caliber during World War I and World War II in another time and space, Zhao Liang finally proposed to imitate the LeFH18/40 105mm howitzer, making it the main equipment of the North Navy artillery in the next twenty years. In addition, the 75mm gun will gradually withdraw from the front line to support firepower, and the artillery companies assigned to each regiment will also be replaced.

Speaking of the 105mm howitzer produced by the Germans in another time and space, the early models were very heavy, and as well as ammunition trucks, it required at least six pack horses. The later derivative leFH18/40 is different. In addition to the more efficient muzzle retractor, the gun barrel was also installed on the gun mount of the 75mm Pak40 anti-tank gun. The new gun mount reduced the overall gun body and improved the fire rate.

In addition, the production of 105mm howitzer is very large, and it has collections in another time and space, whether private or museums, so it is easy to buy two or three doors and take them back as samples. Zhao Xin spent a lot of money on this and got a complete set of design drawings and technical manuals in the German version.

Zhao Xin is certainly welcomed by saving money for himself and saving a lot of money. You should know that every shot of the 122 shells is exchanged for gold by him, which is so painful.

However, he also knew very well that crossing from 75 mm to 105 mm is by no means as simple as thickening the barrel. The shell problem is always a mountain in front of the military-industrial union.

Manufacturing shells is different from bullets. The bullet head and armor-padded process are automatically completed through machines. The shells start with the manufacturing of steel billets and go through more than 30 machining processes before they can be assembled with gunpowder and cartridges.

In the meantime, in addition to lathes, tools, fixtures, and measuring tools, all of which have to be made by themselves, and even the oil-based cutting fluid supply system for processing must be made by themselves. Cutting fluid and Vaseline are large-scale consumables and must be made by themselves. Zhao Xin only buys the money to go to the sea.

So three years ago, the military-industrial consortium led by Zhao Liang began to study how to cross this mountain. In addition, Zhang Bo's oil system and Fanghua laboratory also began to produce oil-based cutting fluid and Vaseline.

While buying shell samples, Zhao Xin unexpectedly got a video of the production of shells in the early 20th century, which made Zhao Liang overjoyed. So he asked a large group of technical workers in the arsenal to read it every day, analyzing each step and the lathe tools and fixtures used in it bit by bit, and determining the process steps. After everyone had seen it almost, Zhao Liang divided the workers into different processing groups and specifically studied their respective processes.

Since the fall of 1790, the military-industrial consortium has selected sites to build artillery factories in various places outside the northeast, and finally selected the foot of Wanda Mountain in the northwest of Boli Town. The first is that the terrain is flat, and the second is that the transportation is convenient. The Kulu River, a tributary of Heilongjiang, is not far away, and can be transported by water in spring and autumn.

By the end of the pulp-turning period in the spring of 1791, the construction of the shell factory, artillery factory, fuze factory and assembly plant broke ground, and a short-distance railway and highway from Boli to here was also built.

It took almost a year for the four factories to be built and many equipment were installed. The people in the power system also cooperated to pull out a dedicated power supply line from the supporting power plant of the steel plant and built a power distribution station. When the factory was ready to settle in and use, the workers on Zhao Liang also made the first batch of fixtures and measuring tools for processing. After that, they tried again and again, and failed again and again. The key was the machining accuracy of the workpiece, which was not enough to be a millimeter away.

The shell factory is busy conquering the mountains, and the steel factory and the artillery factory also have their own responsibilities. Electric slag remelting, medium carbon nickel-chromium platinum alloy steel, self-tightening of the body tube, rifling, chromium plating, etc. Although the electric slag remelting furnace, large drilling machines and boring machines used for boring have corresponding equipment, the problem is not big, but self-tightening of the body tube and rifling are not so easy.

Zhao Liang adopted the approach to selling dog meat with a sheep's head. In the name of a middleman in an underdeveloped country, he customized two sets of 5,000-ton steel pipe hydraulic presses from a domestic factory, which cost Zhao Xinda million. As for the rifle machine, it can only be manufactured by itself. It is enlarged with the proportion of the barrel rifle machine. The equipment material and the knife head are definitely different.

Compared with the other three factories, the assembly plant is the place with the highest safety standards. In addition to high-standard guards, it is also necessary to stay away from the three factories. Workers are all wearing white protective clothing, anti-static gloves and gas masks. Ion fans and ion air rods are also installed inside the factory to eliminate static electricity. You must know that static electricity will cause explosive particles in the air to be detonated, which is really not a joke.

In this way, the thousands of skilled workers trained in Beihai Town over the years worked hard for two years. The departments of steel, metallurgy, chemical, petroleum and other departments worked together to finally manufacture two qualified 105mm howitzers and the first batch of 105*155 high-explosive bombs in the winter of 1793.

According to Zhao Xin's opinion, as long as there are two thousand test shots without accidents, this cannon will be basically successfully imitated, and then it can be mass-produced and replaced.

In May, the Northern Navy began a new round of personnel changes, and Zhao Xin thought about this for a long time. In general, except for Liu Sheng's Western Front troops, all officers who served as regiment-level chief officers for more than two years have made changes.

Although it will take at least half a year to mobilize the chief officer and the army to work together, Zhao Xin must do this in order to avoid the emergence of mountain doctrine within the army and must persevere. According to his considerations, after this personnel adjustment, it will basically stop moving until the troops enter the customs.

According to the order of the Northern Navy Command, Sheng Haizhou and Zhao Jiuzang finally left Pingshi City - the former "Yenisesk". The former, the titular chief of staff of the Northern Navy, will be transferred to Jiaodong to replace Lu Shoushan to fully command the combat tasks of Shandong; the latter was transferred to the Training Command and served as the deputy commander in charge of recruit training, and Wu Siyu was still the chief position.

This chapter is not over, please click on the next page to continue reading! The person responsible for taking over Jiuzang to Pingshi City was Yang Zhongming, the former commander of the 19th Infantry Regiment. Zhou Zhou, the commander of the 12th Regiment, was transferred to Chiyan City, and together with Yang Zhongming, one south and one north, assisting the Cossack Emirates in the battle between Tsarist Russia.

Huji and Mislang, who were stationed in Ulyasutai, were also transferred back, and the two of them were deputy regiment commander Cao Chao and deputy political commissar. Yin Bingwei, who had previously served as his guard company commander, was transferred to Kulun and promoted to regiment commander.

In terms of the commander of the Eastern Front Army, that is, the offensive force in the direction of Shengjing, Zhao Xin planned to promote Mislang to brigade commander and lead four regiments to be responsible for the attack direction from Changchun to Changtu; Pan Xiucheng was transferred from Hunchun to promoted to brigade commander and lead three regiments to be responsible for the attack direction from Changtu to Weiyuanbao Gate.

Lu Shoushan went to Hunchun and was promoted to the commander of the garrison brigade. In addition to stabilizing the newly acquired Tumenjiang line, he was also responsible for the flank attack on Shengjing from the direction of Changbai Mountain.

Chen Jishan, the first master to serve as Zhao Xin's guard company commander, was transferred from Melgen City to Wula, Jilin, and served as the commander of the garrison.

Li Rui's position was promoted to a higher level and served as Chief of Staff of the Eastern Front Force. When Deng Fei was away, he was responsible for all daily and emergency combat affairs.

In addition to the combat troops that were about to go south, the other deputy soldiers of the garrison battalions were also adjusted; most of them were transferred and a few were promoted. All promoted officers would first return to Furdan City to report to the officer training class organized by the General Staff before they could perform their duties.

Zhao Xin is so brain-consuming! You should know that when adjusting personnel, you must consider both the personality traits of each person and the faction of each person.

The current regiment leaders of the Northern Navy brigades are divided into three major factions by outsiders. The first faction is the "Bear Island Sect", including early naturalized generals such as Sheng Haizhou, Zhao Liji, Zhao Jiuzang, Zhao Huji, Mishiro; the second faction is the "Disin Border Sect", with Lu Shoushan and Pan Xiu as the main ones, including Elu, Chen Jishan, Zhou Monkshang and others; the third faction is the "Submission Sect", and the representatives are Samusu and Bayan, and there are Li Yansheng, who has just been promoted to deputy battalion commander of the artillery.

Because the "Bear Island Group" were the first to surrender to Zhao Xin, the foundations of the Northern Navy were also composed of them, so they are the strongest. However, since the "Disposses and Border Residents Group", Zhao Xin has been secretly supporting and intentionally or unintentionally suppressing the "Bear Island Group". The most obvious thing is that Sheng Haizhou and Zhao Jiuzang have been stationed in Siberia in recent years, staying away from the center of power.

As for the division of the "subordination system", it was a bit reluctant, because most of the surrender factions are still ordinary soldiers. Even if the Qing army officers wanted to take the initiative to surrender, when they learned about the "unity of officers and soldiers" system of the Northern Navy, they all retreated.

To put it bluntly, it is still a question of values. The army in feudal society talks about strict hierarchy and governing the army with punishment. Even in the Qi family army, which advocates that "the position is high and low, but the body is low", soldiers who violate discipline must beat military sticks, cut their ears, insert arrows, and even lose their heads.

Zhao Xin finished writing the preliminary adjustment plan, put down his pen, rubbing his slightly sore eyebrows when he heard the knock on the door outside the study room.

"Come in."

The door opened silently, A Miao walked in with a tray, and a teacup with a lid was placed on it. This was to bring ginseng soup to herself.

Ah Miao put the tray on the table beside him and asked, "Are you tired?"

"Can you not be tired?"

Zhao Xin took the ginseng soup and took a sip. The temperature was just right. He was about to ask what to eat tonight, but he saw A Miao's face flushed.

"What's wrong?"

“Well…after this month…”

"Hmm? What do you want to say? What happened this month?"

"After this month, I will be eighteen." A Miaoyue said the voice became smaller and smaller, her face turned red, her head lowered, and her fingers were snatching the bottom of the tray.

"Oh. What gift do you want?" Zhao Xin nodded indifferently. After a while, he suddenly reacted, slapped his forehead, and shouted: "Oh!! Get to know!"

A Miao said ashamed and annoyed: "What do you know?"
