As soon as he made the decision to relocate the arsenal, Wang Ping focused his attention on Zhang Ding in front of him.

"Comrade Zhang Ding, the scale of the arsenal will definitely become larger and larger in the future. An underground factory will definitely not be enough. You will also dig out several warehouses that specialize in hoarding weapons and ammunition. Therefore, the task of building an underground arsenal cannot be stopped, and you have to continue."

Seeing Zhang Ding nodding to show his understanding, Wang Ping immediately turned his attention to the two political commissars.

"Political Commissar Zhou and Political Commissar Luo, without engineers, there would be no underground arsenal that is so easy to defend and difficult to attack. I just said that the scale of the arsenal needs to be expanded, and Zhang Ding's task is still very heavy. So, I plan to set up a direct engineering battalion under the arsenal, with dual leaders of the arsenal and the guard regiment, and Zhang Ding will be the battalion commander!"

"I agree!" The two political commissars had almost nodded and nodded directly to agree.

Wang Ping didn't say nonsense and ordered Zhang Ding directly: "Zhang Ding, you heard it. From now on, you are the battalion commander of the engineering battalion. You will temporarily give you a 500-man staff. You will set up the racks of the engineering battalion within five days. But there is a requirement that the progress of building the arsenal cannot be affected!"

In the next half month, the arsenal not only completed its relocation, but also directly expanded the production capacity of reloaded bullets to 25,000 kilograms per month.

Not only that, political commissar Zhou Yong also built a small-scale iron smelting furnace under the joint guidance of Li Xuebin and Zhou Wu. As long as the raw materials are sufficient, nearly 250 kilograms of pig iron can be refined every day.

In this way, the arsenal has the raw materials for grenade production.

Because the arsenal has a complete set of parts processing machines, Li Xuebin directly used rail steel to create a set of grenade body molds with grooves on the inner wall. In this way, the arsenal has another product, with 200 grenades per day!

Not only that, because of the existence of machine tools such as cutting, grinding, drilling, etc., the mechanical group established by Li Xuebin can create five rifles every day, except the barrel! As long as the barrel can be made, the arsenal can imitate 150 large covers of 38 every month.

If there are enough excellent technicians and several machines are being produced day and night, it can easily produce 300 imitation 38 large covers in a month and be equipped with an infantry battalion!

"The factory director, we must find a way to solve the problem of the machine that manufactures the gun barrel as soon as possible!" Political Commissar Zhou Yong found Wang Ping and said in great anxiety.

"The damaged rifles sent by the front-line troops are basically blown up by the barrel. As long as there is a barrel and the rifle parts stored by the mechanical group can directly arm three hundred rifles and equip a battalion!"

"Also, if possible, it's better to take down two more Japanese coal mines and get some equipment back."

"I asked Professor Li, as long as we can get all the equipment in the two Japanese mines, he will definitely be able to copy all the equipment in the arsenal. In this way, our reloaded bullet output can be directly turned over!"

"In addition, Professor Zhou has developed a production method of smokeless gunpowder. I will be responsible for the raw materials, but you can only solve the relevant machinery and equipment!"

Wang Ping was more anxious than Zhou Yong. Whether it was the trust of the commander of the military region or the concern of the commander of Yan'an, it put great pressure on Wang Ping.

For several days, although he had not gone out, the information from the Military Region Intelligence Department was continuously delivered to him.

Some time ago, after a coal mine and a copper mine were attacked, the Japanese army directly strengthened the defense of these mines. It would definitely be more and more difficult for the arsenal to attack these mines again and again. Therefore, Wang Ping was thinking and choosing to take down a mine in the Japanese through a battle, and then all the equipment in this mine could meet his needs.

After a few days, he found a target, a large iron ore controlled by the Japanese.

However, this iron ore is too big. Although it is far away from the city where the Japanese stationed heavily in heavy troops, the difficulty of taking it down is not low at all.

Because it was far away from the city, the Japanese army directly used this iron ore as a military fortress to build it.

A total of Japanese troops were stationed in it, a reinforcement squadron, a battalion of mine protection teams, and a regiment of the Imperial Army. They defended with several permanent firepower points around the mine. Whether it was a strong attack or a sneak attack, it was difficult to take it down.

At the beginning, Wang Ping also thought about digging a trench to approach the opponent's permanent fire point and shortening the attack time.

However, after the investigation and investigation told him about the terrain around the mine, Wang Ping gave up.

Because the entire mountain is a huge iron ore, the entire mountain can almost be called a stone mountain, with a surface covering only a few dozen centimeters. Not to mention digging trenches, even the troops' offensive bunkers cannot be dug.

Because there was no way to attack, Wang Ping had been unable to make up his mind to send troops for several days.

Now seeing Zhou Yong is so anxious, he really wants to make some achievements in the arsenal to repay the commander and the commander far away in Yan'an.

After some hesitation, Wang Ping finally decided: "Half a month, political commissar, give me another half a month, I promise to get the equipment you want back!"

That night, Wang Ping called the regiment political commissar Luo Wenbo and the chief of staff Yang Xiong to his room, and the battalion commander Hong Tao came together.

Because there were not enough cadres, except for the battalion commander of the first battalion, Hong Tao, who was the former first company commander, was promoted directly to the position of the three battalion commander of the three battalions, the remaining two battalion commanders were temporarily served by political commissar and chief of staff. The original two company commanders only served as deputy battalion commanders, until Wang Ping thought they could become battalion commanders before taking over as battalion commanders.

Based on the sketch of the investigation and investigation, Wang Pingxun introduced the situation of the iron ore.

"Captain, we have fewer cannons. If we are equipped with mountain cannons or field cannons, we can directly call the Japanese firepower one by one!" Political Commissar Luo Wenbo spoke first.

Chief of Staff Yang Xiong directly denied: "The power of mountain cannons is definitely not enough. I have seen the artillery towers and machine gun castles built with reinforced concrete. When a field cannon passes over, it will at most a white spot. Unless the shells are directly shot into the shooting hole, it is almost impossible to achieve the shooting distance of several hundred meters!"

"Unless you use the heavy artillery company of the Independent Brigade to borrow three 1o5mm caliber heavy artillery and shoot directly, maybe there is still hope to destroy it!"

"Don't even think about heavy artillery!" Wang Ping retorted without hesitation.

"That's so heavy, even if you borrow it, you won't be able to transport it to the mountain!"

Luo Wenbo, who frowned, couldn't help complaining: "It's not possible to use cannons, and digging trenches to shorten the attack distance, so what should I do? If it really doesn't work, we will rush forward. I don't believe it anymore. The Japanese can kill us all with a few firepower points!"

Wang Ping didn't even think of answering this complaint, and directly used ignorance to express negation.
Chapter completed!
