"Captain, when you look back and see Gao Jin and them, you have to thank them......"

Before Zhang Ran left, Gai Heiliang said sincerely, not only because the other party risked his life and sent the drawings of the large-caliber howitzer over, but also because of the materials that were in short supply in the detachment brought by Gao Jin and others, such as electric welding machines.

Although in a few decades, the electric welding machine is simply a rotten street thing.

But at the moment, the difference between the detachment having an electric welding machine and not having an electric welding machine can be regarded as the difference between two completely different industrial levels......

With electric welding machine, not only can the rapid welding of steel be realized, the efficiency of using bolt rivets is increased by more than ten times, and more importantly, the steel components after welding can be sealed to a greater extent, which is not achieved by bolt rivets at all......

Take the flame thrower that the detachment is currently developing at the same time, if there is no electric welding machine, even if there is napalm now, this flame thrower will not be possible......

There is even a task of directly modifying the tank gun into a suitable mobile battle, if there is no electric welding machine, Gai Heiliang knows that he can do it, but if he wants him to meet the combat requirements required by Zhang Ran in a short time, he will not dare to pat his chest and promise Zhang Ran anymore.

Therefore, although he knew that Gao Jin and others were a group of guys who made a fortune, and even the militia of the detachment died at the hands of these guys, Gai Heiliang's gratitude to Gao Jin and others was still from the heart.

"Don't worry, I know it!"

Zhang Ran nodded, thought of the drawings of the howitzer and said excitedly: "You can't relax in the research of howitzers, and strive for us to make large cannons and small cannons together when we build cannons......"

Gai Heiliang didn't bother to take care of Zhang Ran, and said in his heart that this small cannon was not done well, so he thought about the howitzer - can you be more down-to-earth?

Where would he understand the obsession that a guy who has traveled back from that era of highly advanced technology wants to realize in his mind?

In Zhang Ran's memory, in any anti-Japanese war drama, even the most divine anti-Japanese drama, the war scenes he saw were always Chinese soldiers who were bombarded by the dense artillery fire of the little devils looking for teeth, but they had never seen the scene of the Chinese soldiers bombarding the little devils all over the ground to find their teeth......

Even the national anthem is sung to brave the enemy's artillery fire, but it is not sung to let the enemy brave our artillery fire!

It can be seen that the soldiers are resentful about this!

Not to mention the battle of Pingtongguan, he himself experienced that he couldn't lift his head up after being bombarded by the little devil's fire, and he personally felt the taste, how aggrieved and unwilling he was!

So he hoped so much, hoping that the detachment would create artillery fire and hit the little devil fiercely!

The bombardment of the hill alone is not enough!

As the saying goes, good is good, more is beautiful, big is good, caliber is justice, range is truth!

A howitzer with a large enough caliber and a long enough range will naturally not be able to fall......

In the eyes of ordinary people, the concept of artillery is often very vague, and the distinction is often between ordinary artillery and cannons - for example, the devil's 92 infantry cannon is an ordinary category.

But in the military, in fact, there is no such difference between ordinary artillery or artillery, in fact, at the current stage, the artillery fire used can be divided into two categories, such as cannons and howitzers, in fact, they all belong to the category of ordinary artillery fire......

The reason why the main artillery fire at the moment is divided into two categories: cannons and howitzers is mainly distinguished by their range and firing elevation angle.

Take the little devil's 92 infantry gun as an example, although it can also shoot at a high elevation angle, it is more aimed at flat fire, and the muzzle velocity of the gun is high, and it is mostly used for frontal attack of forward troops, so it is also a kind of cannon.

Now the detachment disassembled from the tank to prepare the tank gun, which also belongs to the cannon.

Howitzers are different.

It has a large elevation angle, high ballistics, can not be directly aimed and shot, can leap over obstacles to achieve curved strikes, the firing range is generally longer than the cannon, and the power is also greater, and it can achieve fire support for forward positions in the rear of the forward positions, or suppress the enemy's firepower......

Therefore, howitzers and cannons have no distinction between high and low, but more of a relationship between making up for each other's tactical shortcomings.

As for combining the advantages and disadvantages of both guns, the advantages of both cannon and howitzer are guaranteed......

A few decades later, when military technology made great progress, the combination of the advantages of two types of artillery fire was indeed not created - the name is the Gaganon howitzer, referred to as the cannathan howitzer.

But at the moment, not to mention the industrial level that the detachment can't even build a cannon barrel, let's just say that with the little knowledge about artillery fire that Zhang Ran knows, it is simply impossible to directly make a howitzer......

In fact, in the past, not to mention adding howitzers, even if it was a mountain cannon with a little devil, Zhang Ran felt that it was beautiful!

But now it's different, that guy Gao Jin, this time not only brought the welding machine, glue and other things he urgently needed, but also unexpectedly brought the drawings of the cannon!

Zhang Ran felt that this was simply God's purpose for letting him travel back, and let him come back to make up for the irreparable regret of all Chinese people in this tragic memory except for those Japanese spirits......

Think of the close-range flat fire of small mountain artillery, the salvo of long-range large-caliber cannons, and countless shells falling like hail on the position of the little devils, who wailed bitterly in the cluster bombardment, calling the sky should not be, and the earth was not working......

However, the Chinese soldiers can set up a small bench and drink wine and watch the excitement from afar......

Just thinking about it, Zhang Ran couldn't be excited.

After leaving Gai Heiliang's side, Zhang Ran went to the second workshop to take a look around and check the modification of the flame thrower.

If the flame thrower wants to work well, the quality of the cylinder is the top priority - because the flame thrower is powered by compressed gas!

Compressing the gas into a liquid, the pressure on the cylinder is something anyone with a brain can imagine - so this cylinder, the detachment is obviously impossible to make......

Fortunately, Cheng Dongshan and Cui Sanyuan have a way!

In the Battle of Pingtongguan, the little devils not only dispatched a large number of teams, armored vehicles, tanks and others, but also the bombing of aircraft did not stop!

After the battle is over, cleaning up the battlefield is a compulsory course for every army.

The purpose of this is, of course, not to want to put the weapons and ammunition that can still be used into the hands of the enemy.

Therefore, after the battle, the little devil will also clean the battlefield, but the fineness of the little devil's cleaning of the battlefield is too far behind the level of the Eighth Route Army......

And because of the urgency of the war, the little devils are not allowed to clean up the battlefield, and often only the guns and ammunition are collected, and the rest of the things are basically ignored......

Therefore, after every battle is over, after the little devils withdraw, the local militia or something will carry out a secondary battlefield cleaning under the condition of safety, and collect all those bullet casings, fragmented shrapnel and so on......

In the process, the local militia collected several heavy aerial bombs!

Although the detachment has now passed the stage of relying on the explosives from the stink bombs, the explosives are not much for the detachment!

So these heavy aerial bombs were sent to the base area and handed over to the ammunition department.

Originally, after taking out the explosives, the shells of this aerial bomb would be sent to the blacksmith to be melted or cut for other purposes, but I didn't expect to be seen by Cheng Dongshan and Cui Sanyuan.

In order to be unable to manufacture qualified cylinders, the two of them who could not make effective progress in the research and development of flame throwers were all in the light of their eyes after seeing the hollowed out aerial bomb body - that head, that quality, a little modification, isn't it a ready-made flame burner cylinder?

It's like a sleepy pillow, stepping on iron shoes and finding nowhere to go, and it takes no effort to get it......

Now, Cheng Dongshan, Cui Sanyuan and others are modifying this shell, hoping to use the bodies of these aerial bombs into cylinders that can be used as flamethrowers......

Of course, even if the body of the aerial bomb is of good quality, it is not enough to use it directly to make a cylinder, and it is necessary to wrap a layer of steel on the outer layer to increase the strength......

Therefore, the already bulky aerial bomb body is a lot heavier, and the flamethrower made of it is afraid that ordinary people can't carry it at all!

However, it's better than not being able to do it at all!

"Our flamethrower, it is estimated that it will not be able to catch up with the little devils to attack the base area......"

When he said this, Cheng Dongshan Cui Sanyuan Dao was a little sad.

After hearing Shi Yuan, Niu Da and others talk about the power of napalm, Cheng Dongshan and Cui Sanyuan already fully understood how much the flamethrower would help the battlefield if it was manufactured.

Next, the battle of the little devils attacking the base area is directly related to the life and death of the detachment!

The flamethrower is such a big killer, but it can't be built before this, and it is difficult for the two of them not to be sad to catch up with this life-and-death battle!

"Now that you've done your best, don't be sad - the war is still there!"

Although Zhang Ran was also very regretful, he smiled and patted the two of them on the shoulder and comforted.

Out of the second workshop, Zhang Ran of the ammunition department did not go.

The technology of bullet production and reloading is very mature, and he doesn't need to worry about it at all.

Although the composition of artillery shells is not much different from bullets, Mao Zuan and others have accumulated so much experience, and they are not the kind of people who don't know how to draw inferences, so Zhang Ran believes that they will definitely be able to solve it easily!

In the past, it was a bit of a layman commanding an insider, so he didn't mix it up.

Just went around like this, and it was already afternoon when I returned to the detachment.

After a few mouthfuls of food, Zhang Ran went to the farm again.

Maybe it's because the use of earthworms as the main feed has enhanced the immunity of chickens, or because centralized breeding is the first time that it has risen in this land, and there are not so many plagues in poultry, or because the little devils are really evil, making people angry and resentful, and even God can't stand it anymore......

In short, it has been a full year and a half since the construction of the farm began, and the situation that Zhang Ran was most worried about about the outbreak of large-scale plague on the farm has not happened......

The same goes for rabbit farms.

Now, the rabbits in the rabbit farm are already crowded!

In accordance with Zhang Ran's plan to develop centralized chicken raising, when the breeding rabbit population at the detachment headquarters develops to a certain scale, Wang Wenhua will divert some of the rabbits with the breeders who have already learned and send them to the townships and towns that have already been built in the base area, or even to the division headquarters.

In this way, on the one hand, it can greatly reduce the breeding pressure of the detachment itself, and on the other hand, it can also prevent all rabbits, chickens and the like from suffering a devastating blow in case of an outbreak of plague.

However, even if the rabbit herd that has been diverted out has established more than a dozen rabbit breeding sub-farms in the townships and towns in the base area and in the Longyuan Mountain area of the division headquarters, the number of rabbits in the detachment's breeding farms still exceeds 5,000!

And that's not even counting what has already been eaten!

"Now, our detachment has built twelve chicken farms and seven rabbit farms in the base area, and there are also seven on the division headquarters!"

As soon as he saw Zhang Ran, Wang Wenhua immediately came over with the account book and reported: "As for how many chicken farms and rabbit farms have developed in other base areas, although I don't have specific statistics, it is estimated that there are no ......

The number of chickens and rabbits in our own base areas should not be counted, but the number of chickens and rabbits in our own base areas should have exceeded 20,000, and the number of chickens should be about 15,000, and the daily egg production has reached more than 6,000......"

Listening to these figures, Zhang Ran was full of emotion!

In a few decades, for those farmers, these numbers will mean money!

Now, these figures represent more that the soldiers and civilians in the base area can eat more meat, eggs, and nutrition, and their physical fitness can be greatly strengthened!

This is not just for the soldiers and civilians in the base area to have abundant physical strength in the process of fighting against the little devils!

What's more, it is to let the soldiers and civilians in the base area know that under the leadership of the detachment, everyone can live a life where they can often eat an egg and eat some meat every three or five times!

In this way, once the little devils really capture the base area in the future and implement the inhumane ration system for the villagers in the base area, the villagers will not have enough food and clothing, and they will miss the days of following the detachment infinitely......

At that time, no matter how badly the detachment was beaten by the little devils in the next war, as long as there is still one person alive, as long as he raises his arms and shouts, he will definitely respond to every call!

People are like this, they are not afraid of hardship, they are afraid of living a good life!

As long as those who have lived a good life will never be willing to go back to live a poor life that is worse than Coptis chinensis!

If this is the case, even if they are put on the head by the muzzle, they will fight desperately......

That's human nature!

This is also one of the original intentions of Zhang Ran to develop centralized poultry farming.

Of course, being able to raise chickens and rabbits to such a scale in just over a year is definitely something that Zhang Ran did not expect.

The reason why it can develop to such a scale in such a short period of time is entirely because Deng Fang got the sulfuric acid out early, and used the sulfuric acid to make more chemical fertilizers and promote the grain production in the base area!

The grain produced not only fully met the villagers' requirements for a full stomach, but also handed over the surplus grain to the detachment......

With sufficient grain reserves, the detachment had surplus grain to prepare feed, feed the chickens and rabbits......

Otherwise, it would be impossible to achieve such a scale by simply mowing the grass to feed the rabbits or letting the chickens forage for food on their own......

Zhang Ran estimated that this was also the reason why Wang Wenhua only counted the breeding situation in the detachment and the division headquarters.

Because the detachment's chemical fertilizer is not only supplied to the base areas and the guerrilla areas under the leadership of the detachment, but also to a lot of territory for the division headquarters, helping the division headquarters to increase grain production and income, so that the division headquarters also has a little surplus grain for breeding......

The rest of the base areas behind enemy lines will not work.

On the one hand, the detachment's fertilizer production capacity is limited, and it is simply not enough to supply so many areas, and even if it can be supplied, it will be too far away and the blockade of the little devils will not be able to transport it.

And those base areas do not have the conditions to produce their own chemical fertilizers, and they cannot increase grain production - there is not enough food for people, so how can it be used for breeding?

On the detachment's side, a virtuous circle has now been formed, while the rest of the base areas behind enemy lines are still in a vicious circle......

Zhang Ran estimated that because of this, the rest of the base areas behind the enemy did not report the results of breeding, not because they did not want to report, but because of these factors, the comrades in those base areas failed to succeed in breeding......

Thinking of this, Zhang Ran sighed, and said in his heart that although he had traveled back and changed a lot of things, his personal strength was indeed too small in the face of the times......

Not only are the Chairman's troops on the frontal battlefield still facing the little devils, but they have been defeated in successive battles and bloody battles, but even the vast majority of the soldiers of the Eighth Route Army in the base areas behind enemy lines are still living a hard life......

There is still a long way to go to win this war!

After talking about things at work, Zhang Ran looked at Wang Wenhua and said apologetically: "I thought you would hate me, but now I feel relieved to see you like this......

"I used to look down on my brother, thinking he was stupid and bragging!"

Wang Wenhua said: "But since he followed you, I have found that I have admired him more and more, not only killed so many devils, but also became the company commander of the machine gun company, and also commanded the battle - I have never been so proud of him as I am now...... I'm sure so is he himself! ”

When he said this, Wang Wenhua wiped his eyes and said with a sad smile: "Captain, do you know, I am desperately studying breeding technology, day and night, I just don't want to be compared by my younger brother, I want him to know that although I don't dare to fight devils, but with me as a brother, he will always be the second - you say, how can I hate you?" ”

In the end, he even comforted Zhang Ran in turn: "I know that in this battle, thousands of people died in the detachment, and how uncomfortable you are in your heart, captain, you don't dare to face the families of those martyrs, but do you know that since you came, the life of the villagers has been getting better and better, everyone has eaten and clothed warmly every day, and is full of enthusiasm - in the past year or so, I have heard more villagers laughing than I have in the previous thirty-three years combined......

"So Captain, you don't have to feel guilty, you should be proud of yourself!"

"Trust your own choice because you're right!"

"Everyone believes in your choice and is willing to follow you - whether it's blood or tears!"

"Thank you!"

Hearing Wang Wenping's words, Zhang Ran opened his heart slightly, no longer the same as the previous few days, he was always forced to smile......
