After dealing with the matter here, Zhang Ran went to the farm.

In the distance, you can hear the cooing of chickens in the farm.

Because it was summer, the smell in the farm was not small, so Zhang Ran didn't expect to see Deng Fang's father and daughter in the farm.

"Teacher Deng, why did you bring Uncle Deng here?"

Zhang Ran saw Deng Fang with one hand covering his nose and asked with a dry smile.

"It's not that I'm going to bring my dad here, it's my dad who heard that a chicken farm has been established in the detachment, and he has hundreds of chickens at a time, so he has to come over to see if it's okay!" Deng Ying said angrily.

"The taste is too big, I'm afraid of smoking Uncle Deng!" Zhang Ran smiled.

"Out of the way!"

Although Deng Fang was still covering his nose with one hand, obviously he couldn't stand the smell, but his face looked a little happy, and he said: "Looking at so many chickens, I think that there will be hundreds of eggs every day in the future, no matter how smelly it is......"

"How much is that? Now I'm hatching chicks in the hatchery again, and in a few days I'll be hatching chicks again! ”

Wang Wenhua, who had been with him for a long time, said coaxingly: "In less than a year, the entire farm will be full of chickens, and when the time comes, not only eggs will be eaten, but chickens can be eaten often!" ”

"Low-key, low-key!"

Zhang Ran's eyes widened, but he was extremely happy in his heart - this guy is smart, willing to learn and study, and now he has become half an expert in raising chickens.

Hiss......

Deng Fang hissed at the huge chicken farm, took a breath and said: "Such a large chicken farm, if it is all full, you can't raise thousands of chickens at once?" How much food do you have to eat every day? ”

"Our chickens don't just eat grain, but feed with wheat bran, bran and other rapeseed cakes and bean cakes with a small amount of grain!"

Zhang Ran said, taking Deng Fang to visit the huge room dedicated to the fermentation of chicken feed.

In the house, the stonemason Lao Zheng had already opened some bluestone slabs to build a few large stone jars, which were filled with prepared fermenting feed, with a faint smell of sake lees.

"Not bad......

Deng Fang looked at the feed and said: "These grain bran and the like are not easy to digest even for poultry, but after fermentation, they are much easier to digest and can provide more nutrients to the poultry - but just by this, the chicks are okay, but when it comes to laying eggs, the nutrition of these feeds is afraid that they can't keep up, right?" ”

"Uncle Deng is worthy of drinking foreign ink, and he thinks thoughtfully!"

Zhang Ran cocked his thumb fiercely and went over first, and then pointed to the huge semi-underground pools in the middle of the yard and said: "Our secret weapon is the earthworm, using it to feed the chickens, not only can provide enough nutrition for the chickens, but also prevent the plague to a certain extent - this is the secret of our base chicken farm, that is, Uncle Deng, if you ask, if you change someone, I won't tell him if you kill him!" ”

Looking at Zhang Ran's serious appearance, Deng Yingle leaned forward and closed.

Wang Wenhua looked at Deng Fang, who was happy because of these words, looked at Zhang Ran's eyes full of worship, and said in his heart that he deserved to be the captain, he could pat his ass so smoothly and without showing any traces, it seems that he will have to work hard in this regard in the future......

"Chickens grow this big in less than two months...... Captain Zhang, I apologize for saying that you will only draw cakes for the villagers to satisfy their hunger! ”

Deng Fang sighed, looked at Zhang Ran and said, "Captain Zhang, you are indeed a talent!" ”

"Where and where, compared to Uncle Deng, I'm still far behind!"

Zhang Ran said modestly: "And this method of concentrated breeding is not something I came up with, I am also standing on the shoulders of giants......

After the visit, Deng Fang loved you in the company of Deng Ying, and his face was full of thought.

"Captain, what the hell is this chemist?"

Wang Wenhua asked, since this guy has mastered the technology of raising chickens, everyone has to respectfully call him a technician when they see him, and now he is a little trembling.

So after hearing that Deng Fang was a chemist, he couldn't help but have some comparisons, after all, he could raise thousands of chickens, and if the feed was enough, he could raise more!

When the time comes, everyone can eat chicken and eggs!

But what the hell is this chemist? Can you eat it?

"We raise chickens to eat meat and eggs to supplement everyone's nutrition!"

Zhang Ran said: "Although the things made by chemists cannot be eaten, they can help us protect the base areas, protect the grain we have worked so hard to grow, and the poultry and livestock we have raised - the revolution does not distinguish between morning and evening, and the industry does not distinguish between high and low, all of which are dedicated to the great ideals of our Eighth Route Army!" ”

Wang Wenping nodded solemnly.

"Remember in the future, in front of Deng Fang and Deng Ying, respectfully - our Jindong detachment is a small temple, if you want to keep this living Bodhisattva, you have to rely on all of us to work together!"

Zhang Ran said, carefully checked the production of these chickens, and instructed some such as regular disinfection to prevent diseases.

After the matter of the chicken farm was dealt with, Zhang Ran went to the mountains.

For the sake of safety, concealment, etc., whether it is the explosives laboratory of the drill or the machines that were transported back, etc., they were all placed in several caves excavated and expanded after boiling the nitrate.

Originally, the blacksmith workshop was planned to be built in the village, but later the repair of firearms, the manufacture of grenade shells, and the repair of those machines that were brought back all needed the help of the blacksmith, so under the auspices of Wang Changtian, a blacksmith furnace was built in the mountain.

Except for the occasional repair of some farm tools for the villagers in the base area, the blacksmith furnace in the mountains is working most of the time.

Along the way, there were several militiamen standing guard with shuttle darts, and when they saw Zhang Ran coming, they greeted each other with a smile.

"It's been a great job, it's been a hard job!"

Zhang Ran was as kind as a stream, patted the militiaman on the shoulder, and joked with the militia a few more words, and then continued to walk forward.

In the distance, you can feel the heat gushing out of the blacksmith's workshop, and on the side of the workshop, a three- or four-meter-high earthen blast furnace has been erected.

At this moment, the blast furnace is also blazing, and the broken copper and iron collected from the villagers are currently being refined here, and the molten iron is molded into a grenade shell that is slightly larger than a fist.

"Brother Niu, you tap and knock - oops, no, it's cracked again!"

The blacksmith's workshop was heard with the clatter of hammers and chisels, and the cries of apprentices.

"!"

The sound of the cow urn and the angry scolding of the urn also came out, and then the tall figure walked out with the iron shell of the cracked grenade, ready to throw it into the blast furnace again.

"Niu Da, why are you so angry?"

Zhang Ran saw this scene and greeted with a smile.

"Captain Zhang......"

Niu Da squeezed out a little smile, and the child who made a mistake muttered: "You can't knock it with a chisel, this iron is too brittle, and it will crack when you knock it, and as soon as the explosives on Minister Mao's side are loaded in, there will be two pieces of it as soon as it is fried......"

"Take your time, take your time!"

Zhang Ran looked at the cracked iron shell, cheered up Niu Da and said: "There are too many impurities in this scrap iron, it's not your technical problem, don't blame yourself - those guns can't be used in the first place, aren't they just repaired by you with a hammer?" ”

After such a boast, Niu Da was finally a little happier, and scratched his head a little embarrassed and said: "It's not all repaired, there are two guns that are too bad, I changed it, I can only shoot one shot at a time, and after the shot, I have to pull out the shell to ......fight again."

"I know, I've seen those two guns too!"

Zhang Ran smiled: "What's the matter?" If it weren't for you, those two guns wouldn't have been able to hit a single shot, not even a burning stick—and thanks to you! ”

Niu Da grinned, hehe Zhile, his face was red when he was praised by Zhang Ran!

"So don't get angry, take your time, with your technique, I'm sure there is no problem you can't solve!"

Zhang Ran took advantage of the fire to strike the iron and then praised a few words, and then discussed the matter of the grenade iron shell with Niu Da.

Grenades, relying on explosive fragments to injure the enemy.

Therefore, the number of fragments of the explosion greatly affects the power of the grenade.

And the number of fragments that determine the explosion of a grenade is also determined by a variety of factors!

For example, the power of the explosives filled in the grenade, the amount of explosives, etc., and the structure of the iron shell itself will also play a decisive role in the amount of fragments!

At present, Niu Da is starting to solve this problem, and it is also a difficult task that Zhang Ran assigned to him to overcome before leaving the base.
