Because the M1 Garand rifle has not been produced yet, the bullets produced for practice this time were of 7.92mm caliber.

That is the standard bullet caliber of the official rifle produced by the National Army.

As for the monk?

Ever since that day when he said he wanted to stay with Zhou Yu as a guard, he has stayed.

Being an errand boy is pretty good.

Zhou Yu reached out and took the formal rifle handed over by Wei Dayong, then directly picked up a few bullets that needed to be tested and loaded them in.

Then!

Pull the bolt, hold up the gun, aim at the target outside, and pull the trigger.

Just listen to the sound of a gunshot.

The empty wine bottles placed outside the house were beaten into pieces.

But it's not over yet.

Zhou Yu pulled out the cartridge case, continued to pull the trigger, and fired another bullet...and so on until all the bullets were fired.

He touched the muzzle of the gun and felt the residual warmth on it.

Finally, I checked whether there was any damage to the official rifle.

Done with this!

He just put away the gun and threw it to the monk. He turned around and replied with everyone's expectant eyes: "I declare that the first batch of bullets made in the border area is a great success!"

As soon as the words came out.

Inside and outside the arsenal, everyone cheered and became lively.

unknown.

I thought there was something big happening here!

Happy to be happy.

But the success of these first batch of bullets doesn't mean anything. Because right after, they still need to face the test of the second problem!

——The bullet caliber is not uniform!

Most of our army's weapons are obtained from seizures.

This also means.

All the soldiers in the entire army use a variety of guns, and it is difficult to achieve uniformity in bullet caliber.

Therefore, it is not possible to produce bullets in the border area. Bullets must be selectively produced according to the calibers of the weapons used by our soldiers. In other words, the border area must produce bullets of various calibers.

Very troublesome.

But soldiers cannot be afraid of trouble.

To change this problem, the only way is to wait and see when the border area can independently produce guns of the same caliber.

so.

Zhou Yu must speed up the production plan of the M1 Garand rifle and put it on the agenda.

But before that.

There is one more important thing that needs to be done now.

That is to pass the boss's test.

then!

Zhou Yu selected some suitable bullet samples, packed them in wooden boxes, and sent someone to send them to the headquarters.

Let the boss check it first.

Because a military order was issued.

so!

The most important thing now is whether you can pass the boss's test. Only by passing the boss's test and gaining the trust of the headquarters agencies can the big problems that follow can be easily solved.

after this.

Zhou Yu is about to start preparing to expand the second factory building to develop the production of M1 Garand rifles.

but.

In addition to gaining the trust of his boss, Zhou Yu also needs to solve a huge problem.

The problem is...

Ore resources!

Ore resources are very important, and a single mineral source is not enough. Iron ore, chalcopyrite, etc. are needed.

If these are not resolved.

So!

Everything Zhou Yu did before was in vain.

Although our country is said to be vast and rich in resources, some resources are also scarce, such as chalcopyrite.

Border manufacturing has not yet obtained the technology of copper-clad steel, so chalcopyrite used to directly produce bullet casings is particularly important.

and.

Even if ore resources are not scarce!

But under the blockade and precautions of the Little Devils, the Jinsui Army, and the National Army, there is no way to get any ore resources known to the outside world.

And this question.

It cannot be solved by humans.

I'm afraid that even if a big shot like the boss comes forward, it still won't be able to solve the problem.

Zhou Yu was a little irritable at the moment. After ordering people to pack the bullets and send them to the boss, he took a walk alone in the deep mountains and old forests.

He likes mountains.

Because the mountains are clean, you can feel nature here.

Of course, the reason why the main forces of our army are stationed on the mountain side is because the tanks, motorcycles, cars and other transportation vehicles of the Japanese army cannot come in.

It is precisely because of this that they occupy most of the large towns, while the remaining small towns are occupied by the National Army and the Shanxi-Sui Army.

This also leads to the fact that the only places Zhou Yu can go out for walks now are deep mountains and old forests.

while walking.

Suddenly I remembered that today’s system sign-in was not used.

So Zhou Yu decided to go back to the arsenal to sign in before going out for a walk. But at this time, he was secretly thinking about a question.

"It seems that I have never tried it before. What kind of rewards will you get if you sign in in the mountains?"

in the past.

Zhou Yu signed in at the arsenal, so most of the rewards were basic equipment related to the production and manufacturing of weapons.

Occasionally...

There will also be a potion to strengthen the body.

But if you sign in in this deep mountain and old forest, what reward will you get?

Zhou Yu doesn’t know!

Therefore, he was ready to try today's sign-in opportunity here.

After thinking of this, he happened to be too lazy to go back to the arsenal, so he directly communicated with the system in his mind and said: "System, I want to sign in!"

After confirming the sign-in.

The system's beep sounded familiar in my mind.

"Ding! Congratulations to the host for successfully signing in, and you will be rewarded with a distribution map of the ore resources in the northwest Shanxi region!"

Ore resource distribution map?

After hearing the system prompt, Zhou Yu's eyes showed a look of surprise.

did not expect.

The reward for signing in this time was a map of mineral resources in the northwestern Shanxi region. He needed this very much now.

With this!

In the future, there is no need to consider the troublesome task of searching for and mining metal ore resources through complicated exploration methods. Now, he can even directly arrange for people to go to the locations marked on the map for mining and excavation.

It can also directly skip those ore resource points that are complex and difficult to mine, as well as ore resources with poor resource content.

for example!
