Of course, these are still not the main reasons why Lu Yuan decided to develop grenades, the main reason for the development of grenades is because there are too many captured Japanese grenadiers, and there are too few grenades that can be fired.

"This thing, just seems to be useless, only reliable is useful!"

Lu Yuan took the grenade shell and threw it back to Niu Pimple, he knew very well that there was a steel factory, and of course there was no difficulty in casting some grenade shells, but if you wanted to really use the grenades made by yourself to fight devils on the battlefield, there was still a long way to go, and there were still many difficulties to overcome.

Not only grenade shells, but also mine shells have been cast.

The previous mine manufacturing was all done by the Eighth Route Army, and almost all the mines supplied to Lu Yuan were iron-shelled, which was cast by the Eighth Route Army by melting iron juice in a blast furnace using the soil method.

Therefore, in addition to a small number of iron-shell mines, the mines used by the Eighth Route Army itself in the past were more stone mines, wood mines, and the like.

Stone thunder is used to let the stonemasons dig a pit in the middle of the stone and fill it with explosives, and the wood mine is also to catch the medicine according to the prescription, but considering that the lethality of the wood is not enough, some hard objects will be added to it to enhance the lethality.

Such a mine, its practicality can be thought of with your toes, and the effect of scaring devils is far greater than practicality, and sometimes you can listen to it.

The mine warfare played in the movie, which has been artistically processed, is not enough to believe at all.

Now, the steel plant can be put into stable operation, and several blast furnaces can refine several tons of crude steel per day, in this case, of course, all the mines should be replaced with iron-shelled mines, and the technical personnel should be concentrated to tackle key problems and increase the power of the mines as much as possible.

The mine warfare played in the movie, which has been artistically processed, is not enough to believe at all, only when these iron-clad mines are all put into the battlefield, it is very likely to reach the level of the devil man who blew up in the old movie and turned over his horse and cried his father and called his mother, and Lu Yuan is also looking forward to the arrival of this day.

The sample gun thing was done, and Lu Yuan didn't have much effect here, so he took the pimple and a few guards to prepare to go back to the county.

When he passed by the coal mine, he remembered the Umezu Mijiro Kazuki Aoji who was digging coal in it and those Japanese imperial families, so he casually asked about the situation of the guys in the cow lump.

"I asked a few days ago, those guys are much more honest now!"

Niu Pimple grinned and said: "A while ago, it collapsed and killed two royal families, and Xiangyue Qingji's leg was broken, and now he is raising it......"

"Are we all right?"

Lu Yuan didn't care about the death of the two royal families, and if he died, he died.

"Our people are fine—Brother Yuan, if the little devil emperor knew that their people were digging coal for us here, would they be mad?"

Niu Pimple asked happily, and several of the guards who followed laughed wildly.

The snow was getting heavier and heavier, and several people braved the snow to go towards Trojan Horse County, and the laughter came far away in the wind and snow......

United States.

The atmosphere in the United States was also very tense, and every day the newspapers were full of long articles about the active armaments of Germany and Italy, and the Americans in the streets and alleys were discussing when war would break out in Europe and whether they would be involved in the war.

As for the Chinese battlefield far away, apart from some high-ranking government and military officials, not many people care at all.

If Chairman Chiang saw this, he would have been extremely disappointed, after all, the most he wanted for international mediation was to hope that the Americans would come forward, but what he didn't know was that the Americans were more concerned about the possibility of affecting their own Europe, Hitler, Mussolini!

In this world, what everyone cares about most has always been their own vital interests, and who cares about the dire situation of unrelated people?

"Mr. Editor-in-Chief, Mr. Snow's manuscript sent back from China has arrived!"

Inside the Washington Post building, a young clerk knocked on the editor-in-chief's door with a large box.

"Put it there, I'll see it when I'm free!"

The editor-in-chief said, and continued to explain to the people in the printing department without looking back: "The headline reads: 'Hitler's SS has shouted the slogan of world conquest, and once war breaks out, it will be another world war!'" ’”

"Mr. Editor-in-Chief, Mr. Snow said that this manuscript is also enough to make headlines......"

The young clerk put the manuscript box in a corner of the office, and couldn't help but remind him when he saw that a layer of dust had fallen on the manuscript box that he had brought in the first few times.

"In the headlines?"

A person from the printing department who participated in the discussion smiled dismissively: "What's the headline?" Could it be that the Red Army in Yan'an is eating chaff again, working hard for their ideals, and hoping that international friends will give them assistance? Even the government troops of their country were defeated in front of the Japanese, what tricks could those Red Army troops do in the ravines? Do they still think they are the Soviet Red Army? ”

"As long as there is no shocking news like the Nanjing Massacre again, what else can be worth making headlines on the other side of China?"

"Wouldn't it be that there are more than 100,000 of those armies, chased and beaten by thousands of Japanese soldiers, and they can't be defeated?"

The others laughed loudly, their eyes full of disdain and ridicule, as if in their eyes, it was not surprising that those Chinese soldiers fought such a strange battle through the ages.

Everyone in the audience burst into laughter, even the editor-in-chief couldn't help but laugh a few times, looked at the embarrassed clerk and said, "I know, you go out - can you make headlines, I have my own measure on my side......"

The clerk sighed lightly and walked out, he was mainly in charge of Asian affairs, but now it seems that Asia, no one cares.

"Alright, so be it!"

Finally, after the discussion, the editor-in-chief got up and said: "It must be printed as soon as possible, I have a hunch that today's newspaper sales will reach a new high!" ”

"Absolutely!"

"World War II, about to break out, what a shocking title......"

Several members of the printing department laughed, but as they walked out, they accidentally tripped over the box in the corner, and the poorly sealed handwritten documents and some photos were scattered all over the ground.

"I'm sorry, I'm going to clean up!" One of the principals sneered, bending over to clean up.

"Come on, you go and do your own thing, and in terms of printing, you can't delay - be careful next time!"

The editor-in-chief said unhappily, and after a few people left with a smile, he began to pack up the documents scattered on the ground, and then, he was caught by the two photos on the top!
