The sample gun is ready, and all that's left is to wait. .

Lu Yuan left the semi-underground arsenal and came to the steel factory.

Far away, there were many workers who greeted him, and Lu Yuan responded with a smile, asking where Pan Haodi was by the way.

Although it was snowing heavily, it was still in the 40s inside the steel plant, and the workers were working shirtless, imagining the coming New Year.

In the past two months, Lu Yuan has appeared here almost every day, and the workers of the steel mill are already familiar with him, and they have lost the original novelty of looking at a god, and occasionally they can make a joke or two.

Pan Haodi is in his office, with a scruffy beard and long hair, a typical image of an intellectual.

"Pan Gaogong, you don't want to find someone to clean up this office, this smell of smoke ......"

As soon as he entered the door, Lu Yuan couldn't help but nod his forehead and cover his nose, threw the mountain-like cigarette butts in the ashtray on the table into the trash can, and opened the window slightly, and then let out a sigh.

"There are so many things, what should I do if I move around and can't find them when I want to use them?"

Pan Haodi lay on the table without even raising his head, and continued to write chemical formulas there that Lu Yuan couldn't understand at all, while saying, "What are you looking for me again?" ”

"I can't come to you if I'm fine?"

Lu Yuan rolled his eyes helplessly and said: "Coming to the New Year, although the blast furnace in the steel plant cannot be stopped, it will also stop production for two days, so that everyone can rest and rest, and the group is ready to have a reunion dinner for the New Year, you can also come back, after all, the cement factory and the steel plant, you are the first hero, and I will tell you a few words when the time comes......"

"Boredom ......"

Pan Haodi finally raised his head, his bloodshot eyes glared at Lu Yuan from behind his eyes, and said, "When did you start to like this kind of vain thing?" Wouldn't it be nice to have that time to do something serious? Isn't the threshing machine you invented very good, it can beat sorghum and rice, after the trial of the Eighth Route Army, many places around want to buy, and hundreds of units have been ordered, next year we will produce more, and then the people of the platoon gang will take it to the field to sell, if it can be sold, it is a financial resource......"

"Su Yan shouts every day that there is no money, so you can invent more things that are not accurate and practical, and when the time comes, won't we just count on things like cement factories and crude steel?"

Pan Haodi couldn't stop as soon as he said it, and said: "I have discovered now that buying crude steel or something is simply a waste of our steel, and we still have to develop in terms of precision......"

“…… Do you think invention can be invented with a pat on the head? Have the ability to invent one that is both simple and practical! "Lu Yuan is not angry.

Pan Haodi was a flurry, and said depressedly: "I studied technology, and I am not good at inventing ......"

"Have you made any progress on the guns I told you?" Lu Yuan asked again.

The cannon he was talking about was not invented, but a direct imitation of the Japanese army's medium artillery.

Although he still remembers howitzers and other high-powered artillery decades later, it is not helpful at all for the present.

After all, the emergence of any new type of artillery means that there must be corresponding shells, and there is no trace of copper mines around Muma County, and they do not have the strength to build a special artillery shell production line.

In addition, the Japanese army suffered a big loss this year, and it is possible to retaliate at any time, and copying some Japanese artillery fire for emergency relief has become the most practical means at present.

From Tianjin, as well as Datong not long ago, the regiment copied the warehouse of the little devils and brought back a lot of shells, and the Eighth Route Army also captured a lot of shells in previous battles, but there was no suitable artillery fire, which was also one of the key factors in his decision to imitate the Japanese artillery.

Industrialization must not try to save trouble, but now they have to start from the aspect of saving trouble.

"Just now I was asked to go back for the New Year, and this time I was pressed again!"

Pan Haodi said angrily: "The cannons you said have no problems in terms of structure, the key problem is that the strength of our steel is still not enough, am I not thinking of a way?" ”

"It's really not good, let's thicken the barrels, anyway, the terrain on our side, I haven't ever had the dream of dragging these cannons all the time and following the team, and the team will hit wherever it goes......" Lu Yuandao.

"But this dream can be done, the conditions are not ripe now, but there will always be a day when the conditions are ripe in the future!"

Pan Haodi straightened up angrily and pointed at Lu Yuan's nose and said, "You, you have an extremely smart head, but you are too short-sighted, is it possible that you still think that the little devil will hit our county every time, waiting to blow you up?" - I don't even want to talk about you! ”

“…… Okay, okay, I'm short-sighted, you treat me as a fool! ”

Lu Yuan, who touched a gray nose, scratched his head and said: "Actually, it's not that I want you to go back, but your wives let you go back...... How long has it been since you went back to pay your ladies? Is it not in good health? Pay more attention to rest, our group can count on you, I haven't heard of tigers in the mountains here recently, if there is, I can give you the whole tiger whip to make up for it......"

"You'd better keep it to yourself......"

Pan Haodi was anxious, but Lu Yuan had already turned around and went out, and he was angry and stomped his feet hatefully: "Dirty! Shameless......"

But after calming down, there was a hidden shame on his face, and he sighed silently, saying that the furnace had been closed for a few days, and it was time to go back to the county to accompany a few more ladies.

"Captain Lu, was scolded again?"

Several workers saw Lu Yuan's appearance, and said with a smile: "On our side, if you dare to scold you, it is estimated that it is Pan Gaogong and the flight captain, right?" ”

"They are all real talents, they are talents, and they are all a little temperamental!"

Lu Yuan said with a smile, he has been taught a lesson by Pan Haodi for a while, and he just deliberately stimulated the other party with words, which can be regarded as finding a little bit of a field.

"Brother Yuan!"

The cow bump ran in with a snowflake, holding two grenade shells in his hand and said with a smile: "Look, is it like the little devil's thunder?" ”

The grenade shell was cast directly from molten iron, the size of a fist, with pineapple-shaped bumps on the outside, hollow enough to be filled with explosives.

Wooden handle grenades have always been manufactured by the Eighth Route Army, and due to the low technology and easy availability of raw materials, throwing grenades has almost become a regular tactic of the Eighth Route Army, even more than shooting.

It's a pity that the power of the wooden-handled grenades made by the Eighth Route Army is average, and occasionally there will be a situation where one is thrown out and two halves are exploded, and the detonating charge that was later filled was replaced by the nitrogenated starch explosive provided by Lu Yuan, and the situation has changed slightly, but it is only slightly improved, and the effect is still not very good.
