The head of 911 was sure of the things that Sun Hao did in the arsenal, and he was very sure, they didn't expect that Sun Hao would be able to do such a big thing by giving Sun Hao such a little money, and now it depends on how to manage it.

How to give full play to the maximum value of copper ore and iron ore, this requires Yan'an's efforts.

And Sun Hao has returned to the arsenal with copper at this time, as soon as he returned to the arsenal, Sun Hao asked the workers to carry the copper mines, and he went to the laboratory, and now Sun Hao cares about whether the laboratory has experimented with qualified steel.

"Still not?" Sun Hao went in to take a look and found that those people were still experimenting and looked tired.

"No, it's very well matched, we already know the German steel and the Japanese steel contained in those other materials, but this amount, we can't get it out, our laboratory, the equipment is very poor, we can't get it out at all,

Even if it comes out, we don't know how to add it, this has a process, we are currently there, but there is no such process, Comrade Sun Hao, it's really not good, forget it, it's really difficult! Li Yu said very depressedly.

"Give up, Made, there are never two words in Lao Tzu's dictionary!" When Sun Hao heard this, he couldn't help but burst out foul language, and he was also a little anxious.

"But!" Li Yu is still very low.

"There is nothing but, you must get it out, if you don't get it out, you spend so much money, isn't it in vain? We are poor, but we don't have so much money for us to squander like this! Sun Hao said to Li Yu, and he was holding the notebook of those records and sitting there watching.

"Battalion Commander, Director Yu and Chief Engineer Huang are looking for you!" One of Sun Hao's guards came over and said to Sun Hao.

"Well, I'll go out first!" Sun Hao put down the notebook and came out as he spoke. As soon as he came out, he saw Lao Yu and Lao Huang standing there.

"Something?" Sun Hao asked.

"Yes, that, the workers outside moved it, it's all copper, where did you get it?" Lao Yu pointed outside and said very happily.

"We refine it ourselves, and every day in the future, copper will come over, and then we will be able to produce bullets by ourselves!" Sun Hao said to Lao Yu, still thinking about the steel in his heart.

"Did you really find it, and did you get it out?" Lao Yu was even more shocked, looking at Sun Hao and asking nervously.

"Got it out, is there anything else? Now I'm in a hurry here, and I need to deal with it inside! Sun Hao asked Lao Yu, Sun Hao didn't want to ask about other things at all, after all, steel is the most important thing now.

"I don't have it on my side, don't worry, that copper will help us too much, but we may not need so much copper on our side!" Lao Yu said to Sun Hao.

"Why don't you need it, we still have to produce bullets then, there is no copper, how can we produce bullets, all those coppers are put away for me, and we will still be useful when the time comes!" Sun Hao said to Lao Yu, and actually said that copper is not of much use here, how is this possible?

However, you can't blame Lao Yu, Lao Yu doesn't believe that his arsenal can still produce bullets, and now they are all reloading bullets.

"Okay, I'll go in first if it's okay?" Sun Hao said to them.

"I still have something, that, can those blacksmiths make them stop, what are those things they are fighting, what the hell is it, now we still have a task on our side, we need to repair 3,000 guns a month, you do this, our arsenal will not be able to complete the task by then!" Lao Huang said anxiously to Sun Hao.

"Are they all out of parts?" Sun Hao asked.

"Not yet, but what are you going to build?" Lao Huang looked at Sun Hao and asked very puzzled.

"Continue to let them fight if they don't finish the fight, and you will come to me again after the fight, in addition, the task matter, I have already told the front finger that we have not had a task to repair the gun in the past two months!" Sun Hao looked at Lao Huang and said,

Lao Huang heard it and was stunned for a moment,

And Sun Hao has already entered, continue to look at the analysis of the data, Sun Hao needs to find a breakthrough from those data, start the experiment again, the next week, Sun Hao is in the laboratory, continue to do experiments, analysis, and then continue to do experiments, or no qualified steel can be experimented!

"Hey!" Sun Hao sat there, sighing, and Lao Yu and Lao Huang didn't dare to come to Sun Hao at all now, and they didn't want to see Sun Hao and Sun Hao, and now he was staring at the steel.

"Battalion commander, Chief Engineer Huang has come over, he said, the blacksmith has finished making it!" A guard came in and said to Sun Hao.

"Oh, it's done, okay!" Sun Hao nodded as he spoke, stood up, and began to walk outside,

Then came to the blacksmith's side, those blacksmiths all looked at Sun Hao, they didn't know what Sun Hao was doing to build those things, those parts and components added up, more than fifty kinds, four or five hundred!

"Carry these parts to the innermost, turn on the lights, and people who are studying mechanical engineering, come here!" Sun Hao shouted at the workers and engineers, and the engineers heard it and immediately passed.

And those workers also followed, and soon, the large and small parts were moved to the innermost, Lao Yu and Lao Huang also watched, and Sun Hao began to take those students, take those parts, and began to assemble them into machinery.

Soon, one by one the machinery was installed, including the motor, Sun Hao had already installed it, and there were various belts that Lao Yu bought, and Sun Hao also installed them.

"Alright, put the copper in the furnace and light it!" Sun Hao said to those workers, those workers still don't know what these machines are for, but they are now doing things according to Sun Hao's orders, after all, Sun Hao came over, and it has indeed brought great changes to their arsenal!

Sun Hao stood there and waited for more than half an hour, until all the coal in the furnace was burned, and then Sun Hao asked the workers to take out the copper inside and put it on a machine.

Sun Hao began to press the switch, and those copper pieces began to be squeezed, and then they were cut into small short strips, Sun Hao looked at those small short strips, took them to the scale, and weighed,

At the same time, Sun Hao also took a few 7.62mm bullet shells, which were washed cleanly, and after making sure that the small short strips cut out were about the same, Sun Hao asked the soldiers to pour those small short strips into the funnel of a machine.

Then as soon as the motor was turned on, the sound of a thump began to sound, and then the men saw that on the other side, a large number of stamped cartridge casings came out.
