The 911 leader was sure of what Sun Hao did in the arsenal, and was very sure of it. They did not expect that giving Sun Hao such a little money would be able to do such a big thing. Now it depends on how to manage it.

How to maximize the value of copper ore and iron ore requires efforts from Yan'an.

Sun Hao had already returned to the arsenal with copper. Once he returned to the arsenal, Sun Hao asked the workers to transport the copper mines, but he went to the laboratory. What Sun Hao is concerned about now is that there was no qualified steel in the laboratory.

"Are you still not?" Sun Hao went in and found that the people were still doing experiments and looked very tired.

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

Even if it is made, we don’t know how to add it. This is crafted. We currently do not have such craftsmanship. Comrade Sun Hao really can’t do it. Forget it, it’s really difficult!” Li Yu said in a very depressed mood.

"Give up, Made, I never gave up in the dictionary!" When Sun Hao heard this, he couldn't help but swear words, and he was a little anxious.

"But!" Li Yu was still very depressed.

"There is nothing, but you must make it out. If you don't make it out, you will spend so much money. Isn't it in vain? We, the Eighth Route Army, are poor, but we don't have so much money to squander like this!" Sun Hao said to Li Yu, while he was sitting there watching with those records.

"Battery Commander, Director Yu and Chief Engineer Huang are looking for you!" A guard from Sun Hao came over and said to Sun Hao.

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

"Is there something wrong?" Sun Hao asked.

"Yes, that, the workers outside moved all of them, they were all copper. Where did you get it?" Lao Yu pointed outside and said happily.

"We extracted it ourselves. Every day in the future, copper will come, and we will be able to produce bullets by ourselves!" Sun Hao said to Lao Yu, still thinking about steel.

"I really found it, and I made it out?" Lao Yu was even more shocked and asked nervously as he looked at Sun Hao.

"I've made it up, is there anything else? Now things are in a hurry, and I need to deal with them!" 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 here, don't worry, that the copper has helped us too much, but we may not need so much copper!" Lao Yu said to Sun Hao.

"Why don't you need it? We will still produce bullets at that time. Without copper, how can we produce bullets? All of them will be used for me. Then we will still use them!" Sun Hao said to Lao Yu, and even said that copper is not very useful to this place. How is this possible?

However, Lao Yu cannot blame him. Lao Yu doesn't believe that his arsenal can produce bullets, and now he is reloading bullets.

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

"I still have something to do, that, can those blacksmiths let them stop? What are the things they are shooting? Now we still have tasks here. We need to repair 3,000 guns every month. If you do this, our arsenal will not be able to complete the task by then!" Lao Huang said anxiously to Sun Hao.

"Have they finished all their parts?" Sun Hao asked.

"Not yet, but what else are you creating?" Old Huang looked at Sun Hao and asked in confusion.

"So let them fight before they finish the fight. Come and find me after the fight. In addition, I have already told the front finger about the mission. In the past two months, we have not had the task of repairing guns!" Sun Hao looked at Lao Huang and said,

Lao Huang heard this and was stunned for a moment.

Sun Hao has already entered and continues to look at the analytical data. Sun Hao needs to find a breakthrough from the data and start the experiment again. In the next week, Sun Hao is in the laboratory, constantly doing experiments, analyses, and then continuing to do experiments, but he still has not been able to produce qualified steel!

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

"Battery Commander, Chief Engineer Huang has come over. He said that the blacksmith has finished making it!" A guard came in and said to Sun Hao.

"Oh, the production is over, okay!" Sun Hao said, nodded, then stood up and started walking outside.

Then we arrived at the blacksmith. The blacksmiths looked at Sun Hao. They didn't know what Sun Hao made to make. The parts were large and small, with more than fifty or four or five hundred!

"Transfer these parts to the innermost part, turn on the lights, and come over to mechanics!" Sun Hao shouted to the workers and engineers. When the engineers heard it, they passed by immediately.

And the workers followed, and soon, all parts of all sizes were transported to the innermost part. Lao Yu and Lao Huang also watched, while Sun Hao began to take the students, take the parts and start assembling them into machinery.

Soon, a series of machinery were installed, including the motor, Sun Hao had already installed it, and Sun Hao also installed the various belts that Lao Yu bought.

"Okay, put the copper in the heating furnace and light the furnace!" Sun Hao said to the workers. The workers still don't know what these machines are doing, but they are now doing things according to Sun Hao's orders. After all, Sun Hao has come here, which 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 burned. Sun Hao then asked the workers to take out the copper blocks inside and put them on a machine.

As soon as Sun Hao pressed the switch, the copper blocks began to be squeezed and then cut into small short strips. Sun Hao looked at the small short strips and took them to the scales.

At the same time, Sun Hao also took a few 7.62mm bullet shells, which were washed clean. After confirming that the small short strips were cut, Sun Hao asked the soldiers to pour the small short strips into a funnel of a machine.

Then as soon as the motor was turned on, the sound of dong dong began to sound, and then the people saw that on the other side, a large number of stamped shells came out.
