Because it was the first time to refine, Zhang Ran and Deng Fang stayed in front of the tower all night, not daring to relax at all.

Although there are many emergencies, such as leakage at a certain connection, such as the size of the cylinder and other aspects are not suitable, which affects the preparation efficiency of sulfuric acid and ammonia......

These things were recorded by Zhang Ran and Deng Fang one by one.

However, I will not say what kind of adjustment will be made immediately, but I will observe it for a while and then make adjustments!

After all, once the tower cylinder is to be adjusted, the copper smelting furnace must be rebuilt.

This kind of earthen furnace thermal expansion and contraction, if frequent cessation of fire, will greatly affect the service life of the copper furnace, not to mention, the observation of all aspects of the tower cylinder is too short, there will also be some omissions and imperfections, so it is necessary to observe more, strive to find the most problems at one time, and transform once, it is necessary to produce the greatest effect.

Only in this way can the process of tower cylinder method be perfected as soon as possible and qualified sulfuric acid can be prepared.

Of course, the main problem is that it is now infinitely close to August, and all kinds of crops are about to enter the critical node of growth, and it is necessary to produce chemical fertilizer as soon as possible, and top dressing all crops, so that it is possible to get the maximum harvest possible this autumn......

The morning star gradually falls.

The morning sun rises slowly......

Zhang Ran and Deng Fang, as well as all the people who worked in the copper smelter, had not slept all night, and their eyes were red.

In fact, there are many, many people who haven't slept all night in the base area!

There are many ordinary people who stay outside the copper smelter all night and refuse to leave, staring at this side!

There are also landlords such as Ma Chengbang and Zhao Wanlin!

Because the copper smelting furnace started to start, there was no special notice to several people, but after these landlords learned the news of the start of the copper smelting furnace, it was already the second half of the night......

But after hearing the news, Ma Chengbang and the others no longer had the intention of continuing to sleep, but rushed over overnight with their families, and at this moment, like those ordinary people, they were staring at the copper smelter!

If it weren't for the militia guarding the copper smelter, and without Zhang Ran's order, no one was allowed to enter at will to disturb their work, I am afraid that Ma Chengbang and Zheng Wanlin and other landlords and ordinary people would have rushed into the copper smelter a long time ago!

It wasn't until the sun rose that the gate of the copper smelter slowly opened.

"Look, everyone, it's Team Zhang and Deng Gong, they're out!"

The moment they saw Zhang Ran and Deng Fang, everyone was boiling, staring at the two intently.

Behind them, a few men cautiously pushed a few chicken carts over!

Two of the chicken carts had small clay jars on them, and one of the chicken carts was a large piece of golden copper!

At this time, copper is not cheap!

Everyone can be sure that the copper on the chicken bus can be exchanged for hundreds of catties of good grain!

But everyone's eyes didn't look at the copper block, but focused on the two small clay jars, and everyone's hearts hung in their throats!

"Get out of the way, be careful!"

Wang Laogui, who was in charge of the guard, led the soldiers to maintain order, the contents of the tank were highly dangerous, and they didn't want any problems at this time!

The clay jar was slowly placed on the ground, and the pungent smell spread!

"Team Zhang, speak quickly, have you succeeded in the end!"

"Yes, yes, the food in the field is still waiting for fertilizer......

The common people were impatient and shouted one after another.

It can be said that the people have firmly supported Zhang Ran and supported the detachment in the past few months, of course, there are various reasons for the detachment to give everyone the land and other benefits, but the most important reason is because of this fertilizer!

If this fertilizer is really successful, the grain production in everyone's field will be greatly increased, and then everyone will no longer have to go hungry!

I'm afraid that they, the common people, haven't eaten a few meals since they were born with memories, and the memory of hunger is simply deep in the bone marrow!

They dreamed of starvation, but unfortunately, it was out of reach before!

Until Zhang Ran appeared, he took out the fake fertilizer last time and made a promise to open a fertilizer factory!

They realize, or really have a chance to get rid of hunger......

"Folks, calm down, let's believe in Captain Zhang and Deng Gong!"

"That's it, Captain Zhang, they have done so much work for the fertilizer, and they must also want to make fertilizer at one time to benefit everyone, and at the same time, they will not let their hard work be in vain, but this kind of thing is not about eating and sleeping, it has to come step by step, so we have to give Captain Zhang time to Deng Gong, if it fails this time, then it doesn't matter, there will be time in the future, as long as Captain Zhang and they don't give up, sooner or later the fertilizer will always be studied......"

Ma Chengbang, Zhao Wanlin and others were shouting loudly, seemingly helping Zhang Ran and others speak, but their eyes were obviously much more nervous than those ordinary people!

Nothing else.

Because of this fertilizer factory, they agreed that the detachment would distribute their own land to these people, and even took out the money to support Zhang Ran to start a fertilizer factory......

For this fertilizer factory, Ma Chengbang, a big landlord, may have a lot of good things at home, but Zhao Wanlin, a small landlord, has almost hollowed out his family by now!

If the fertilizer can't be made, they're going to go bankrupt!

Ay......

Zhang Ran let out a long sigh.

This sigh simply made the hearts of many people chuckle, and Zheng Wanlin and other small landlords almost fainted.

Zhang Ran grinned and said, "There is good news and bad news, which one do you want to hear first?" ”

"Good news, good news, good ......"

Everyone went crazy and screamed.

"Captain Zhang, don't sell it, just say it, you just said that throat, but you almost scared us all to death, do you know......"

Ma Chengbang, Zhao Wanlin, Zheng Tianming and other landlords were about to cry.

"Okay, okay, I'm not going to tease everyone!"

Zhang Ran said with a smile: "The research and development of sulfuric acid, although it is not a complete success, but it is enough to produce phosphate fertilizer, and ammonia fertilizer has been successful, as long as the test is carried out to see how much concentration is suitable for fertilization, and the ratio is proportional, it can immediately act on crops......"

Before the words fell, everyone went crazy.

Crying, screaming, scurrying, kowtowing to thank the Bodhisattva for his blessing......

It's just a group of demons dancing.

Not only the common people, but even Zhao Wanlin, Zheng Tianming and other landlords were like this, and Zhang Ran, who was frightened, hurriedly lined up all the soldiers who had prepared in front of several or two clay jars, just in case.

In this case, it is obviously impossible to pretend to be forced, but Zhang Ran is still happy.

He believes that many years later, the current scene will definitely go down in history and be remembered by all Chinese!

Among them, the best performance was Ma Chengbang, trembling, squeezing into the soldiers, and kneeling down for Zhang Ran as soon as his legs were weak.

"Master Ma, what are you doing here?"

Zhang Ran was taken aback, and hurriedly helped Ma Chengbang and said: "I know that you can make a lot of money if the fertilizer is successful, but you are investors in the fertilizer factory, and this money should be made, so you don't need to give me such a big gift......

"Captain Zhang, it's not a matter of making money now, this fertilizer is successful, that's a great thing for the benefit of the country and the people, I don't know how many people want to suffer less hunger because of Captain Zhang, and live a few more years, I, Ma Chengbang, thank you for all the people......" Ma Chengbang said with tears in his eyes.

“……”

Zhang Ran looked straight at it, and said in his heart, I don't believe that you, a big landlord, are still so concerned about the world?

But seeing Ma Chengbang crying, even if the other party is acting, but with such realistic acting skills, Zhang Ran really couldn't say the sarcastic words, and comforted him again and again.

Ma Chengbang stopped the old tears for a long time, pointed to the two cylinders and asked which one was ammonia fertilizer and which one was sulfuric acid, and finally said: "The mother acid brought back from the first time is so white, why is the sulfuric acid we made black like ink?" ”

"How else can I say there is good news and bad news?"

Zhang Ran said depressedly: "The reducing agent we used in the process of preparing sulfuric acid this time is coke, so it has become like this...... But don't worry, Mr. Ma, although these sulfuric acids are waste products for the pure sulfuric acid that we want to use to prepare nitrifying explosives, they should be no problem when used to produce phosphate fertilizers! ”

"That's good, that's good......"

Hearing this, Ma Chengbang breathed a long sigh of relief, obviously not caring about when clean sulfuric acid could be produced, but just asked when the phosphate fertilizer would be produced, and when the ammonia fertilizer could be successfully deployed and could be used for fertilization......

After the people went crazy, Wang Changtian yelled: "Folks, follow me to mine phosphate rock, when the sulfuric acid comes out, we can immediately produce fertilizer......

With a snort, everyone ran out.

Even Ma Chengbang, Zhao Wanlin, Zheng Tianming and other landlords all carried hoes and chased after them, and together with everyone, they dug with everyone at the phosphate mine site designated by Wang Changtian, and they didn't care about a lot of blood blisters with their hands......

"Lao Gui, go and get the gas mask in the warehouse, use it for everyone to make acid, and after the mask is bought, let everyone wear it!"

Zhang Ran greeted Wang Laogui and said: "Tell everyone, don't wear a mask and gas mask because you feel uncomfortable, I will come over to check at any time, if anyone dares to wear a mask and gas mask in accordance with the regulations during production, as long as they are discovered, they will be fired immediately, and they will not be allowed to participate in any work of the detachment in the future - do you understand?" ”

Although he knew that this order he gave was a bit harsh, for the sake of everyone's safety, he had to give this order in the most severe way.

The common people are used to being free and loose, if they don't say something to death, these people will not take such a request seriously at all, and when there is a problem in all aspects of the body in the future, it will be too late!

Zhang Ran didn't want to watch everyone have no cure due to physical reasons, and finally die miserably......
