Seeing Liu Yucheng's surprised look, Dong Ku smiled.

"Sir, do you think the equipment has arrived, and when the ground is opened in June, and it freezes again before it is completed, how long will it take for us to put all the equipment up?"

"That's right. The climate of the Northeast is like this, and the construction period is too short. ”

Looking at Dong Ku, Liu Yucheng asked bottomlessly: "But ...... start construction now?"

"Sir, I'll take care of the specific things of the construction, but the personnel want you to prepare, we need a large number of personnel, and we also need a part of the absolutely reliable construction personnel to ensure that the secret is not leaked."

"It's no problem, you can find some coolies from remote places, transport them by car, don't let them know where they have arrived all the way, go directly to the construction site, and send them back secretly after completion, without contact with the outside world along the way, so that you don't have to worry about the news being leaked."

"Good way!"

Dong Kuzan said, and added: "The Japanese army's cement plant needs to start immediately, we need a lot of cement, and it's not good to do the one or two thousand tons they have in stock." ”

"Okay. There is no problem with starting work, the core technical personnel of the main body are all there, the dark hall has been screened two or three times, and the rest of the problems are not big. ”

After glancing at Liu Luocheng, Dong Ku secretly rejoiced that it was absolutely correct to keep Liu Luocheng by his side, otherwise, these trivial things were not something he could think of at all.

Not to mention anything else, even those traitors, pro-Japanese elements, and landlords and bullies who were angry with the people, and all the secret halls were sorted out within five days after the occupation of Harbin. However, these are public trials, and they are also to avoid wrongful killing of good people.

And those who have savings and a good reputation, Dong Ku not only did not touch them. Also given a heavy responsibility. The reason why they are rich without stealing or robbing shows that their thinking is avant-garde, which is also the difference between rich and poor people, and the difference in concepts.

Not to mention public security, just those temporary policemen in the dark hall kept Harbin very quiet, which made Dong Ku have an illusion. This is the ice city of later generations, not Harbin at war.

Pressed the willow defeat city began to gather the workers without mentioning. On the day Dong Ku returned to Harbin, the position of the two cities was quiet. The Japanese army honestly stayed in the distant position, allowing the advance army to clean up the position where they were originally stationed, and they did not even send troops to burn the corpses and minced meat. Just watched the smoke rising from afar, and in various moods, stayed in place.

The fighting in Qiqihar also stopped. According to Dong Ku's suggestion, the Japanese army was allowed to transport the corpses and burn them to avoid the plague after civilization. It is also to reduce the chances of the enemy using corpses as cover on the battlefield.

The two-day battle came to an abrupt end. In addition to preparing and waiting, it seems that everything has returned to calm.

These days, the technical personnel recruited from the surrounding areas and some special talents who have been displaced by the people have gathered in Harbin, so that a military camp is full of people.

They have nothing to do for the time being, but not to mention that they have registered now, and the white flour steamed buns every day make them as excited and down-to-earth as the New Year, and they can wait for the time to start working with peace of mind.

After Dong Ku handed over the task of defending the twin cities to Junko, he began to draw drawings with some professionals day and night. Design a series of factories.

After being in contact with them for a long time, Dong Ku noticed something. Their ideas are indeed too far behind, not on the same level as those Jews on Crescent Island, and many things Dong Ku has to explain for a long time to make them fully understand their intentions, far less than the Jews who can understand it at all, and can quickly accept things that are different from what they have learned. After all, these things are a bit ahead of their time. There is a certain gap with their knowledge. This is still Dong Ku's philosophy and technical standards as close as possible to the World War II period, otherwise, it will be impossible to absorb and digest it.

Fortunately, these people are not stupid, and after understanding it, all kinds of whimsical ideas emerge one after another, which makes Dong Ku tired at the same time. I secretly admired the unique intelligence of the Chinese.

After five days of preparation, a few kilometers away from the poison gas research facilities of the Japanese army in the bungalow, the snow was cleared by a sea of workers. More than 40,000 workers gathered here, they were all summoned by Liu Chengcheng to arrange Mishan and other remote areas, to take care of food and shelter, and a large ocean in a month, so that these people were crazy crowded to get on the bus, and in the car curtain was tightly covered, and the direction could not be distinguished, they were pulled to the vicinity of the bungalow.

They were simple farmers, hunters, or people who had nothing to do in the winter, and when they arrived, they began to clear the snow and go to the nearby woods to cut down trees and build shelters.

In the huge camp, piles of fires burned. From the sky, these fires are very regularly distributed and very neat.

Dong Ku didn't let the guards follow, the four guards hung far behind Dong Ku, and Dong Ku measured between these fires with a few people in the dark hall and the technicians in charge of construction here, and commanded to light dry wood in the circle where the painting was made, and watched it burn.

After the fire had burned for an hour, the coals would be cleared aside, and then a group of figures with shovels would rush to the hot ground, quickly digging up the roasted ground, deep or shallow half a meter at a time, and then piling the coals into the pit, putting dry wood, and burning.

In less than a day, a trough more than five meters wide and deep, reaching under the frozen layer, and more than ten meters long, appeared on the construction site covering an area of two or three thousand acres like the steps of the Great Wall, and then was covered with a wooden cage house.

On the construction site, piles of timber were brought in from the mountains in the distance, and piles of stones were piled up all over the ground. The captured war horses, who already understood Chinese, were put on the horse plow one by one and acted as the main force of transportation.

On the distant mountain, a pot of sawdust was fried with ammonium nitrate and turned into explosives, and in the muffled roar, patches of rocks collapsed. Almost all the stonemasons around are gathered here, they are also in charge of food and housing, a large ocean in a month, living in the mountains, the granite that has been blown down is broken into stone bricks, and the small ones are directly broken into rubble in the concrete.

After two busy days, everything was basically formed, the gables of the houses were open, there were no doors and windows, and a picket of steaming earth was sent outside, spread on the ground, frozen into soil particles, and then pulled away by horses and plows, and sent to Shuangcheng and Acheng in a steady stream.

On the construction site, the people were no longer so dense in two days, except for the figures who transported stones and picked up soil, more than half of the tens of thousands of people were gone.

At this time, they were all more than two meters deep underground, under the bright electric lights, picking at the dirt, and toiling like moles. With the swing of their shovels, picks of dirt were sent to the surface, to the Twin Cities, and with it spread a few hundred meters behind the defensive position, where a second new trench was built.

Although there are no high-efficiency machinery in this era, these sweaty figures make Dong Ku feel the effect of a large number of people. It only took three days for the ground to be hollowed out.

As the earth between the passages was hollowed out, the entire underground was slowly connected.

Looking at the underground at this time, the frozen layer more than two meters deep is supported by wood, similar to a mine, but it is only fragmented, and not all of them are supported by rows. There is also an earthen wall several meters wide at the junction between each entrance to avoid the roof collapsing

The depth of the excavation has reached three meters under the frozen layer, and with the support of the top, the depth continues, leaving only the earth platform that supports the top.

This is the crystallization of several days of hard work by Dong Ku and dozens of professionals. They couldn't build a factory on the ground, so they simply broke ground and built it underground, so that when the machine arrived, it could be installed directly in place.

As the depth of the underground reached the requirement, the stone bricks were carried down the ground, and then the rubble and the sand were paved with the seepage layer, and in less than five days, the construction of the factory officially began.

This is the arsenal in Dong Ku's planning, and it is a place to produce various components and finished products. Cannons, the manufacture of cannon barrels will also be completed underground.

As for the bullets and shells, they are separated here by two or three kilometers, each built on the ground. After all, that thing is too dangerous, and once it explodes, it will destroy the entire underground, so it is safer to leave the position of the lathe and build it on the ground.

On the ground here, power plants will be built, sand turning plants will be built, and simpler, less demanding components will be used to make artillery and tanks and the like. Electricity is provided for the entire industrial park.

There are also workshops for large equipment such as water pressure, oil pressure, cold forging, and heat treatment, which are used as reserves for the manufacture of large artillery and tanks.

Dong Ku is somewhat risky to gather everything together, but the air defense here will also be the most powerful, he believes that as long as the artillery bombs can be produced, not to mention the current horizontal bombers, even the dive bombers cannot break through the interception of the bombs carried by the sky balloons, which will destroy all the planes that dare to approach. Coupled with the dense anti-aircraft guns and anti-aircraft machine guns, these twenty or thirty square kilometers will be monolithic, and there is absolutely no need to worry about aircraft bombing.

At the time of the start of construction here, the Shuangyashan coal mine began to coke in large quantities to prepare coke for the steel plant. Steel mills, built near several iron mines, first smelt iron, and then send it to a steelmaking furnace to smelt the needed steel.

Steel-making furnace and smelting furnace, the Japanese left a lot, slightly renovated, and increased the technical facilities of the top blowing, in the case of industrial oxygen in place, the two steel-making furnaces with a daily output of ten tons can not reach double, but they can certainly improve more than three cities.

Under the eyes of the army, Dong Ku is methodically building an industrial system. At this time, if the Japanese could see the construction and conception of this industrial area, they would be frightened crazy. This is a complete military industrial complex far beyond their current level, a place where they can produce any weapons without having to build another factory elsewhere. (To be continued......)
