Late June.

Morning.

Zhao Gang's guards drove him from Zhao Jiayu's regimental headquarters to the explosives factory located in the mountainous area on the right.

The summer sun was shining down, and even though it was still a few hours before noon, the outside of the house was like a stove.

Fortunately, the road leading to the explosives factory in Zhao Jiayu is a compacted gravel road, the speed of the three jumpers is very fast, the driving skills of the guards are also very stable, and the wind blows on the body is particularly cool.

In less than ten minutes, Political Commissar Zhao approached the mountainous area where the explosives factory was located.

Continuing along the newly dug winding road, the three jumpers drove towards the main factory of the explosives factory, and many mule carts could already be seen along the way.

The board truck is a new type of board truck produced by Zhao Jiayu Machinery Factory, which is responsible for pulling ordinary mules and transporting raw materials or semi-finished products for the production of explosives.

Along the way, Commissar Zhao was pondering.

In order to avoid bombardment by devils, the explosives factory divided the production line into ten steps, and then the ten steps were divided into eighty-seven small factories, which were located in the mountains within a radius of five kilometers and distributed along winding mountain roads.

Originally, he thought that this kind of decentralization would reduce production efficiency and cause a lot of problems in management.

It did at first.

The construction of eighty-seven factories, the integration of production lines, the training of workers, and the lack of management personnel made him almost lose his hair, if it were not for Zhang Wanhe who sent dozens of chemical talents from the headquarters arsenal in time, if it were not for the detailed Chinese technical manual accompanying the explosives production line, there are technical and management aspects, and even pictures and film teaching, and the mechanical master is really powerful, I am afraid that when the special team went to kill Honjo Fan, I would not want to start production.

In the follow-up production, there were many troubles, and all kinds of problems were endless, but relying on detailed technical manuals and sufficient manpower, he and dozens of chemical technical experts were difficult to solve.

When everything began to get on the right track, and after dealing with various problems became more and more handy, Zhao Gang suddenly found that this kind of production line layout actually had an unexpected benefit.

The dispersed production line can not only carry the explosion, but also resist accidents, and if a factory has a problem, it will not affect the overall production. At the same time, if a problem occurs in one factory, the experience gained during the process can also help other factories to make corresponding improvements. The competition between factories and the striving for the top has also strongly promoted the improvement of output and quality.

The technicians from the headquarters gradually understood the explosives technology, the workers became more and more skilled, and the management methods became more and more mature, and slowly, the more than 80 factories became smoother, and began to be like a whole machine, with higher and higher output and better quality.

From more than 100 kilograms per day, to nearly a ton of explosives per day...

When the kill of Honzhuang Fan, Boss Chen supported a chemical master, as soon as the expert shot, he knew if there was any, after the chemical master Fu adjusted the production line for more than half a month, dealt with the backlog of dozens of production technical problems, the output of the explosives factory directly skyrocketed, and so far, the daily production capacity is four tons.

And it is expected that in the middle of next month, production will increase again.

Experienced this process from beginning to end, and participated in it, which greatly broadened Zhao Gang's horizons, made him feel very emotional, and benefited a lot in his heart.

"Commissar."

When I came to the cave-type main factory located in the rock wall, the person in charge came out to answer it.

"How's the factory going?"

Zhao Gang gets straight to the point.

"It went very well."

The tone of the person in charge was delighted, even excited:

"The new technical experts are very good, not only solve all the technical problems, but also very good at management, the production line has been adjusted, and it is expected to reach 10 tons per day from July 1st."

"The follow-up will be relatively slow, and we have to wait for the training of new workers to come up before we can continue to improve."

"Okay."

Zhao Gang nodded with satisfaction.

Subsequently, the two talked about some other issues, exchanged problems and experiences encountered in the factory, and then Political Commissar Zhao left, and before leaving, he said to the person in charge:

"Since July 1, I have left one ton of explosives in the warehouse every day to make small explosives bags, and I have other functions."

"Yes."

The person in charge directly agreed.

Ten tons of explosives per day is already more than the digestion capacity of the troops, and the headquarters arsenal produces grenades and mortar shells, which can only digest up to six tons per day, leaving one ton easily behind.

Subsequently, Political Commissar Zhao continued to drive in the direction of Ping'an County on three jumpers, until he reached the end of the highway and came to a place called Ge Village, which had gathered a large group of people at this time.

These people were dressed in uniform clothes, and each carried tools, shovels, shovels, carts, and poles in their hands. It is the construction brigade.

"Commissar."

As soon as I got out of the car, a man in his forties wearing a shabby gray military hat and carrying a map in his arm walked over and greeted him with a smile.

"Master Luo, is the surveying and mapping completed?"

Zhao Gang asked.

This man in his forties is a civil engineer supported by the headquarters, who once presided over the construction of highways abroad, and resolutely returned to Japan to resist Japan when he knew that the devils had invaded the Kannai.

"It's done."

Master Luo spread out the map on the car of the three jumpers, pointed to the lines on the map, and replied:

"There are three mountain horse roads from Gecun to Ping'an County, and they are 30 kilometers away from the intersection of Ping'an County Highway, but only one in the middle can pass through the board car, this road is very simple, the amount of work is relatively small, and the remaining two can only be walked or passed by mules and horses, and the amount of work is very large."

Engineering mapping is cumbersome and a huge amount of work, but with accurate and detailed hydrographic maps, it's much simpler.

"It will take a long time to widen the middle lane into a two-lane road that can pass 10-wheeled trucks."

Zhao Gang asked.

In the plan, Ping'an County will be the main gateway to the outside world, so the highway will naturally be of a high standard, able to accommodate the rapid passage of the incoming tank troops.

"A two-lane carriageway for a 10-wheeled truck?"

Master Luo was a little surprised, but after thinking for a moment, he said:

"With the size of the manpower of my brigade, in about half a year, this road is full of stones, and two bridges have to be built in the middle, which is very difficult."

Naturally, he has seen the kind of ten-wheeled truck, which looks very similar to the big truck in the United States, but the horsepower is greater, a full 157 horsepower, and the diesel engine is full of torque, and the structure is even more incredible, and the smooth road can run with ten tons, plus more than five tons of dead weight, that is to say, the road needs to be able to accommodate thirty tons at the same time.

"Half a year."

Zhao Gang frowned:

"Is there a way to speed things up?"

Half a year is too long.

"Give more manpower, use explosives on a large scale, and preferably get a few engineering excavators and bulldozers."

Master Luo said without hesitation.

Then he added:

"I will drive these machinery and equipment myself, and I have also contacted a few old guys in Chongqing to come over, and they will drive machinery and equipment."

Although it has not been long since I came here, Master Luo has completely liked this place, compared to the smoky national capital, although the foundation of this mountainous area centered on Zhao Jiayu is a little worse, but the atmosphere is much better, everyone is full of passion for work, wholeheartedly do practical things, occasionally some moths can be quickly removed, in this case, the speed of development is incredible.

In addition, the treatment is much better than the legal tender of the national government, and you can eat well and dress well, and even eat well.

"It's easy."

Zhao Gang immediately made a decision:

"I'll give you 25,000 road builders, 200 kilograms of explosives a day, and then I'll also think of a way to build machinery."

Nearly 1,000 young cadres who came out of Kang Da, under the semi-militarized management system, coupled with the modern management that I heard from Boss Chen, the construction brigade under Zhao Gang's responsibility has entered the right track, and the work is highly motivated and efficient.

"Twenty-five thousand."

Master Luo, who was shocked by the big hand, swallowed his throat and said:

"It can be opened to traffic in two months at the earliest, and if there is construction machinery, it can be faster."

"Try to make the road as strong as possible, the stronger the better."

Zhao Gang admonished.

At the same time that Zhao Gang and Master Luo began to discuss the construction of the road, on the road outside Ge Village, Xu Husheng, the commander of the first battalion and one company, rushed to the direction of Ping'an County with his company, which had expanded to more than 600 people.

As a battalion and a company, at this time, the first company of the whole regiment was naturally equipped with new general-purpose machine guns, and at the end of the team, there were six new 82 mortars.

·····

The next day.

Early morning.

Zhengtai railway side.

"Start testing the wireless detonator signal."

Wang Gensheng held a telescope and looked at the devil patrol on the railroad tracks in the distance, and ordered in his mouth.

According to the latest wireless detonator manual, you need to test it in a single place, because the environment will affect the signal transmission distance of the detonator, trees, terrain, and even the magnetic field.

Following his command, one of the warriors took down the huge wooden box on his back and took out an iron box with an antenna, like a radio station.

Turn on the power switch, unfold the antenna, and presumably the detonator button box, revealing a red button.

At the same time, another fighter with a fist-sized receiver ran to a distance of five hundred meters and stood by.

The red button was pressed, and after a few seconds, the opposite warrior waved the chess piece in his hand, and the meaning of the flag was very simple - there is a signal, no fault.

Then the fighter with the receiver in hand continued to run into the distance, testing every distance, and finally stopped when he reached a distance of 1.6 kilometers, and at this point, the receiver still had a clear signal.

"One point six kilometers."

Wang Gensheng licked his lips:

"This thing is exciting!"

One point and six kilometers, it is impossible to detonate the rope before, as for the wire detonation, it is also very troublesome, such a long wire is not light, and the railway is the territory of the devil, he has no time to recycle the wire afterwards, and the wire is not cheap.

In comparison, the fist-sized receiver is too cost-effective, and Boss Chen is almost free of charge, and the concealment is higher.

"Up."

Wang Gensheng waved his hand.

Taking advantage of the break in the devil patrol, he led people to plant four packs of explosives totaling 500 kilograms near the railway, one of which was close to the tracks, and the other three were placed outside the tracks, which is the location where the devil's train is expected to turn over.

After that, the detonator on the street led the people away from the tracks, hiding at a distance of 1.5 highways from the railway, quietly looking at the tracks in the distance.

The sun is gradually rising, and as a special team, everyone is naturally full of patience and quietly waiting for the target to appear.

"Captain, look at the little devil..."

Suddenly, a member of the team holding a telescope spoke with surprise.

Everyone looked and found that about a large group of devils were advancing along the carpet search along the railway, and they had spread as far as a kilometer around the railway.

"This stance..."

Wang Gensheng narrowed his eyes:

"There are big fish!"

Although the devils attach great importance to the safety of the railway, they have not reached the extent of sending a large team to search in a carpet manner, and there is only one possibility for this kind of abnormal action.

Everyone was immediately refreshed.

"Be careful to hide and don't let the devils find out."

Wang Gensheng reminded.

The rest of the team members are also very conscious, have concealed their figures, integrated into the environment, more than three years, intensive actual combat, so that the special team at this time more and more mature, especially in the area of concealment, is the peak.

In the distance, on the railway.

A devil captain pulled his voice:

"All of them gave me wide eyes, looked closely, fresh marks on the ground, turned over dirt, moved stones, focused on these places, found anomalies and excavated directly, checked if there were wires."

"Don't let go of a trace."

The new chief of staff of the North China Front, Oshiroto Sanji, was coming, and considering the experience of Miyano Michiichi, Yoshimoto did not dare to be careless at all, and ordered all localities to strengthen vigilance and send special personnel to supervise it.

After fighting with the Independent Regiment for so long, the First Army has also accumulated rich experience, and naturally knows that the Independent Regiment has special squads, which often sneak attack and ambush Imperial officers, and also know that the Independent Regiment has recently appeared by means of wire detonation of mines.

Knowing the enemy's means, it is naturally easy to be prepared.

Explosives are highly concealed, and a single burial site can be handled very concealed, which is not easy to find.

However, long wires need to be buried underground, and the distance makes it impossible to completely dispose of the buried traces, which can be easily detected by careful inspection along the railways and roads.

"Hey, hey, hey..."

In the grass, looking at those busy devils, Wang Gensheng grinned at the corner of his mouth:

"Little devils, you are outdated, and you don't play the old set anymore."

After the devil left, after a while, on the railway in the distance, a plume of black smoke appeared in Wang Gensheng's sight.
