The political commissar suddenly walked in with an uncontrollable smile on his face.

The division commander immediately asked: "Have you received any good news?"

The political commissar nodded with a smile: "Comrade Zhou Cheng sent a telegram, and the national-savior army he commanded was about to expand again. He planned to organize the absenteeism they rescued from Jingxing Coal Mine into two 800-person reinforcement battalions as killer weapons, hide in the mountains for secret training, and give the Japanese a fatal attack at critical moments."

The teacher understood Zhou Cheng’s deep meaning as soon as he heard it: “This idea is good!”

"This time the National Salvation Army caused the Japanese to suffer such a big loss, and the Japanese will definitely launch heavy troops to retaliate in the future. Comrade Zhou Cheng prepared for the future and secretly formed two strengthening battalions. When the Japanese attacked, they sent them behind the Japanese army to find flaws. At critical moments, they could play a role in breaking the deadlock."

"The division headquarters completely agrees that they will expand two more battalions. If there are conditions, it will be fine to expand three more battalions!"

The political commissar knew that the division commander would definitely agree with this matter, so he changed the subject and continued: "I also support them in expanding their troops."

"But Comrade Zhou Cheng encountered a problem. As the killer weapon of the National Salvation Army, the existence of the two independent battalions must be kept confidential. There are only a few cadres who have the ability to be battalion commanders of the National Salvation Army, and they are all stared at by Japanese spies and war zones. No matter who is transferred to the independent battalion to be battalion commanders, it will attract the attention of the Japanese and puppet troops and war zones, resulting in the independent battalion being exposed before it is used as a killer weapon."

"In order to avoid this situation, Zhou Cheng notified us to help arrange two independent battalion commanders and deputy battalion commanders responsible for the ideological work of the troops. They arranged cadres below the independent battalion company, which would be more conducive to confidentiality."

Gao Xing, the commander of the division commander gave an order without thinking: "Give them the two battalion commanders and two deputy battalion commanders and political commissars, you must not only be capable, but also be absolutely loyal to the party. Finally, you must tell them that while renovating absenteeism, you must unconditionally obey Comrade Zhou Cheng's orders."

"In addition, three company commanders and six instructors who serve as deputy company commanders are dispatched to the scene."

"Although Comrade Zhou Cheng said in the telegram that the National Salvation Army solved the remaining company commanders and deputy company commanders, there were only so many of them, and they expanded the two battalions at once, so there were definitely not enough qualified cadres."

"I don't want to see them tear down the east wall and repair the west wall, which will eventually affect the overall combat effectiveness of the National Salvation Army."

"Information shows that the National Salvation Army has attracted the attention of the Japanese North China Front Army."

"No matter how hard they tried, their influence was in Shanxi, and the Japanese army could only transfer troops from Shanxi garrison to besiege them, and their troops and equipment were very limited."

"Now that the North China Front Command has been targeted, the Japanese army can send troops from more places to reinforce Yangquan and siege the National Salvation Army."

"So the retaliatory sweep they will face next will definitely be unprecedented. The National Salvation Army must seize the time to recover its strength as soon as possible and be prepared to fight."

"By the way, let's give several Eighth Route Army troops operating near the National Salvation Army a order: when the Japanese army assembles heavy troops to attack the National Salvation Army, they will not be spared, so they must speed up the training speed, restore combat effectiveness as soon as possible, and prepare for combat."

After the officers of the two independent battalions were resolved, Zhou Cheng became the boss and handed over the task of recruiting soldiers and forming an independent battalion to Tang Yufeng and Chen Zhengyu. He led more than 20 absentees who passed the review and plunged into the arsenal!

The power that drives power generation equipment comes from boilers, and coal is what provides energy to boilers.

It is easy to solve coal. After several days of visits and searches, the troops have discovered three small coal mines in the defense zone, and the coal mines obtained can fully meet the needs of the arsenal.

But there is one problem that is particularly difficult to solve.

Burning coal will smoke. If there is no wind, the black smoke can rise to a height of 100 meters.

The existence of smoke pillars can be seen for a few kilometers.

It can be said that it is an accident once or twice. After more times, the fool also knows that there is something wrong with the mountain.

With the strength of the Japanese Special High School, if you find something here, you will definitely find the existence of the arsenal and then send an airplane to blow up the arsenal.

Although the factories where the arsenal are located are all in caves, and the Japanese can't even blow up the most powerful aviation bomb, the Japanese can dispatch planes to bomb the raw materials, weapons and ammunition entering and leaving the arsenal, and can also directly send troops to attack the arsenal...

No matter what situation is, Zhou Cheng wants to see, so the problem of coal-fired black smoke producing a large amount of black smoke must be solved, otherwise the arsenal may attack at any time.

It took a lot of effort to get the equipment in the cave. They are the guarantee for the national rescue army to survive behind enemy lines. If they are bombed, they will have no place to cry.

Factory director Kong Dewen didn't have to worry about this problem when he was working in Taiyuan Arsenal before, so he thought about it for a long time but couldn't think of a solution.

Li Gong from Jingxing Coal Mine also frowned.

When I was working in a coal mine, the coal mine was in the hands of the Japanese. There was no air strike, so there was no need to prevent smoke. Just build a large chimney dozens of meters high.

Chimneys are definitely not built here, as it is not conducive to keeping confidentiality and will also cause people to be suspicious.

Moreover, the chimney also has the function of holes and smoke. If the black smoke produced by the boiler is really discharged through the chimney, it is possible that the smoke column will rise to a height of 200 meters.

Tan Tianming, who had broken a leg and was in charge of all the disabled soldiers in the arsenal, suddenly suggested: "Captain, can we find a way to disperse the black smoke? As long as the smoke is not very thick, it should be dispersed if it rises to a height of more than ten meters!"

"The dense forests deep in the arsenal, and the big trees around them are twenty or thirty meters high. As long as the black smoke scatters before they float out of the forest, it will definitely not attract the attention of the Japanese and puppet troops."

"I remember during the Long March that in order to avoid the troops being exposed to their goals due to cooking, the kitchen team would dig the chimney a little longer, leave a few more air outlets, and cover the branches on the air outlets. Then the black smoke generated by the cooking team would dissipate and would not gather together to rise to the sky."

The more Zhou Cheng listened, the brighter his eyes became.

He suddenly thought of an ink making factory he saw when he was performing a mission in his previous life.

The reason why burning coal and firewood produces a lot of black smoke is that the carbon in the coal and firewood has not yet burned out and rises into the sky with carbon dioxide.

The raw material used in ink making factories is the carbon particles taken away by carbon dioxide.

The workers deliberately built a long chimney to allow black smoke to pass through the chimney. Under the action of gravity, the carbon mixed in the air slowly accumulates in the chimney.

After removing the carbon in the air, the black smoke will become much lighter.

Then, using the method proposed by Tan Tianming just now, divide a flue into several flue channels, so that the fainter smoke can be dispersed into the air, and there will definitely be no chance to form a smoke column.

When he thought of it, Zhou Cheng used the mountain to build a nearly fifty-meter-long flue on the roof of the factory. After reaching the end, a flue suddenly divided into four flue, and each extended forward for more than ten meters.

After reaching the end, the four flue channels were divided into sixteen smaller flue channels.

At this time, the exit of the flue was in a dense forest.

Zhou Cheng asked the troops to cover a large number of branches at the flue entrance, and further disperse the smoke without blocking the flue entrance...

"Boom..."

The generator started to operate under the driving force of the steam boiler. The coal in the furnace burned rapidly, and the black smoke generated entered the flue along the chimney...

Zhou Cheng was guarding the exit of the flue. The smoke dissipation effect of the entire smoke exhaust system was very good. After layers of treatment, the original black smoke had turned into a few smoke. It was blown clean before it even reached the height of the treetops!

"It's done!" Zhou Cheng shouted excitedly.

When we returned to the arsenal, the huge power generation equipment had been started and several technical workers from the coal mine were connecting to the power.

Zhou Cheng waited less than ten minutes before seeing Li Wenfeng running over with excitement: "Report to the team leader, Director Kong, we have completed wiring and can start the machine!"

Kong Dewen did not respond and turned to Zhou Cheng.

For the arsenal, the moment of starting the machine is particularly important and must be announced by the regiment commander himself.

"Are the raw materials ready?" Zhou Cheng knew what Kong Dewen meant. Although all he had to do was just a situation, it was of great significance, so he asked immediately.

"Don't worry, the leader, you're ready!" Kong Dewen quickly answered.

"Because this is the first production of the arsenal, all the workers who add the feed are experienced. When the arsenal is on track, they will change new people."

Zhou Cheng nodded and quickly turned his gaze to the machine in front of him: "Power power on...start the equipment..."

"Boom..."

The small cave was immediately covered by roar, and the machines that the soldiers wiped were finally turned.

Kong Dewen walked quickly to the next side of the equipment and ordered while checking the operation of the equipment: "You start to put the bullet shells... start to put the firing medicine... put the bullet..."

In less than ten minutes, a shiny bullet was pushed out, followed by the second and third...

The workers next to them immediately became busy. Five bullets were loaded into paper boxes folded from kraft paper in rows, filled six rows of thirty bullets, sealed the door, and then placed neatly into the bullet box.

Kong Dewen grabbed a bullet in advance and checked it quickly. A long-lost smile finally flashed from the corner of his mouth.

He walked quickly to Zhou Cheng, handed the bullet in his hand, and then reported: "Captain, from the appearance, there is no problem with these bullets. Do you know if the charge amount and seal inside the bullet casing meet the requirements."

Looking at the bullets in his hand, Zhou Cheng was both excited and nervous, and was very anxious to order: "Send them to the shooting range to test and you will know if they have passed or not."

"Director Kong, today we are just trying to produce 500 bullets with the bullet shells we produce ourselves, and then reload 500 bullets with the bullet shells recovered from the battlefield, and then send them all to the shooting range for testing to see if there is any difference, and by the way, find out the pass rate of these bullets..."

In just over two hours, Zhou Cheng requested a thousand bullets to be produced.

More than two hours later, the test results were also released.

The bullets produced by the new shell are exactly the same as those captured by the Japanese army, and there is no difference when firing.

The quality of the reloaded bullet is slightly worse, and the target within 100 meters is hit 100 times, which is no different from the new bullet; the error of shooting a target of 150 meters is about ten centimeters, and the error of shooting a target of 200 meters is more than twenty centimeters, but it basically does not affect the use.

Because on the battlefield, except for a few riflemen who will shoot the enemy at a distance of 100 meters, most riflesmen will put the enemy within 100 meters before firing.
