In the general perception, sulfuric acid is something that is yellow-brown or other colors and exudes a pungent odor.

But in fact, pure sulfuric acid is colorless and odorless, and when the concentration reaches a certain level, it is even a colorless and odorless colloidal viscous liquid, and only those sulfuric acid that contains too many impurities because the extraction process is not in place will show a variety of colors and exude various odors.

Regardless of the color and smell, it is not the smell of the sulfuric acid itself, but the impurities contained in the sulfuric acid.

What Zhang Ran got was colorless and tasteless sulfuric acid that was less than a small wine glass, which was somewhat similar to jelly, and there was a texture that people couldn't help but take a bite of.

said that he only gave a little bit, Deng Fang was quite gentlemanly, and his words counted.

Zhang Ran looked at the glass jar in Deng Fang's hand depressedly, and said that his primer test would definitely not succeed at one time, how could such a little be enough?

"That's all the mother acid, how much more do you want?"

Deng Fang snorted coldly: "The function of the mother acid is to absorb the flue gas to form sulfuric acid, once it fails, the mother acid used for absorption can not be used, unless we try to make sulfuric acid once successful - what do you think is the possibility of our success at one time?" ”

Zhang Ran knew with his ass that a group of guys who were crossing the river with stones wanted to make relatively pure sulfuric acid at one time, and the probability might be lower than winning the lottery with five million!

"Just such a little mother acid, and it is divided into several copies for testing, of course, if you can save it, you can save it!"

Deng Fangdao: "When we successfully prepare sulfuric acid, you can test the primer as much as you want, but now, at most, we can only give you so much......"

"That's fine......"

Seeing that Deng Fang did not have any intention of making concessions, and at the same time, Zhang Ran also knew that compared with the primer experiment, it was more important to retain enough parent acid for sulfuric acid preparation, so he laughed and compromised.

After such a circle, it was time for lunch again.

The miners gathered one after another, waiting for the meal with bowls in their hands, while the recruits and veterans gathered outside the military canteen specially opened for the soldiers, waiting with the same eyes.

The air is filled with the smell of chicken broth.

Although the people share a chicken with hundreds of people, it is estimated that there are only a few shredded meat in each person's bowl at most, and the number of soldiers is relatively small, but there are also dozens of people, and the chicken that each person can get is estimated to be extremely limited.

But even so, this meal is still a rare meal for everyone, so when they looked at Zhang Ran, everyone's eyes were full of heartfelt gratitude.

Because of his appearance, life in the base is getting better and better!

Everyone has their own fields, and after they are busy with the work in the fields, they can still work for the detachment to earn points, and in the past, they only ate some lard and saw some oil meat every once in a while, but now they can drink two mouthfuls of chicken soup and dip some chicken every other day.

They are heartfelt and satisfied.

"Now the life of our base is getting better and better, but folks, don't forget what this is all about!"

Wang Changtian said with a full leadership style: "We poor people can have today, it is because of Captain Zhang, because of the Eighth Route Army, we must keep in mind this kindness, and closely unite around Captain Zhang and the Eighth Route Army, only in this way, our current good life, that can we live ......for a long time."

"Support Captain Zhang, support the detachment, support the Eighth Route Army!"

Hundreds of people shouted happily, sniffing vigorously, sniffing the tempting aroma of chicken soup, and feeling the taste of happiness in that fragrance.

Deng Ying led a group of children who followed the learning of calligraphy to line up at the front of the team in the Minfu canteen, every time they eat, these children can get a little preferential treatment, and the people certainly have no opinion on this.

Hearing the villagers chanting slogans, a group of children followed the loud barking, especially the little dog, barking that the green tendons on their necks came out, but Deng Ying was peeking at Zhang Ran and smiling softly.

Zhang Ran greeted everyone with a smile and nodded to Deng Ying, while noticing that Kang Ting seemed to be holding something in his hand, trying to get close to Deng Ying like a thief, but he looked a little embarrassed.

This guy is really a thief!

Zhang Ranxin said, but he didn't stop it, after all, this kind of thing has always been a consensual thing, and he has no reason to stop it.

The kitchen deliberately left a chicken leg in Zhang Ran's bowl, which looked particularly attractive in the clear chicken soup.

Although I really want to be high-spirited, I want to put the chicken legs back like those great men in history, and resolutely share the weal and woe with the soldiers, so as to show off my personality charm to the greatest extent.

But in the end, Zhang Ran didn't.

He didn't even smell these things in the past, but now he can gnaw on the big fat meat as a radish, and he feels that he can eat it all by himself with a bowl of big fat, and he is really reluctant to give up his favorite chicken legs.

"I am now the backbone of the detachment, if my body collapses, what will the detachment do? What should the fighters do? What should the people of the detachment do? ”

Zhang Ran comforted himself, and was a little embarrassed to go back to the house with the chicken leg and bite it down hard - it was so fragrant......

While enjoying the chicken legs, Zhang Ran also sighed, this great man is really not something that ordinary people can be, just like himself, the temptation of a chicken leg can't be stopped, and he still wants to be compared with the great people?

Zhang Ran felt that it was better to forget it.

The chicken is a treasure.

Meat can be eaten to supplement nutrition, bones can be ground into bone meal and added to chicken feed, which can increase the egg production rate of hens, and can also dry distill bones to extract phosphorus, etc., the effect is not small.

Of course, there are phosphate mines near the detachment, but there is no need to dry the bones, not to mention that the current chicken bones cannot be left - even Zhang Ran eats a chicken leg by himself, and after eating the meat, the bones are chewed and swallowed, not to mention those villagers and soldiers.

As for the fluff on the chicken, it can be used as a filling for down jackets after being steamed and deodorized.

In the decades, down jackets were generally made of duck down, not chicken down.

Probably because of evolution, ducks are often active in water, so duck down has the property of waterproofing and has a better warmth effect.

In contrast, chicken down is much worse, once it encounters water, it will stick together, it is not easy to dry, not to mention, the warmth effect is not satisfactory - this is also the reason why people always say that the soup chicken is not the soup duck.

But even though chicken down has so many shortcomings, Zhang Ran still wants to use chicken down to make down jackets.

The winter here is very cold, and if the soldiers are out fighting in winter, they will definitely need cotton clothes and other types of protection from the cold.

But there is very little cotton here, and once the number of people in the detachment increases, the cotton used on the quilt alone is not a small amount!

What's more, if the sulfuric acid experiment is successful in the future, cotton will have to be used to nitrate to make nitrocellulose, and at that time, cotton will become an important strategic material.

Although chicken down is not as good as duck down, the warmth effect of filling in clothes is at least not worse than cotton.

If you can replace some of the cotton with chicken down, you can reduce the burden on the detachment a lot, and you can be regarded as the best of both worlds.

As soon as the meal was finished, Lu Yan came over with a happy face and took out a bag and put it in front of Zhang Ran.

In the bag was a bunch of yellow-orange bullets, and seven or eight grenades—not the kind of thing made by the detachment, but the best grenades of the regular army.

Zhang Ranxi, who was worried about the ammunition, asked, "Where did it come from?" ”

"Where else? Those guys from the security team stole it out! ”

Lu Yan said with a smile: "Last time you were in the county town in the name of opening a delicatessen, encouraging those security teams to exchange ammunition for food, those guys are addicted now, as soon as they see food for sale, they secretly ask if they can exchange ammunition, I will let our people in the county secretly ......exchange food for them."

"Director Lu, you are getting more and more sophisticated in doing things!"

Zhang Ran laughed, in this bag, in addition to more than 400 bullets and seven or eight grenade bombs, there were also many bullet shells, which immediately greatly relieved the tight ammunition reserves of the detachment preparing to fight the Cangshui Self-Defense Force!

"As long as those security teams are willing to change, then we will always change with them!"

Zhang Ran encouraged, and then said with a smile: "Also, let our people talk to those soldiers in the security team, in addition to these ammunition can be exchanged for food, other things can also be exchanged, such as the things on Xu Song's motorcycle, as long as they can bring it out, let's change ......."

This time it blew up two big trucks and brought back two car engines, and the harvest was huge.

But he didn't blow up a motorcycle, Zhang Ran regretted it deeply!

The car is powered, with a lot of horsepower and enough power, which is of course a good thing, but it also has its disadvantages - it is too heavy and not suitable for handling at all, especially fast handling.

It's different when the engine of the motorcycle is removed, and people with a little more strength can run with it!

It would be useful if the grinding wheels were developed in the future, and the engine of a motorcycle was used to modify a cutting machine with grinding wheels, which was used to steal the kind of big rails that the little devils couldn't lift......

"That motorcycle, it can be treated as a treasure by Xu Song, if this thing is stolen by someone, Xu Song must not go crazy......" Lu Yan was a little worried.

"He's crazy!"

Thinking about the grievances between the detachment and Xu Song, Zhang Ran snorted coldly: "This guy, relying on hundreds of guns in his hand, he will do all kinds of evil in the township, our detachment will have to clean him up sooner or later, if he is directly mad, it is best to go crazy, and our detachment will save trouble......"

After arranging these, Zhang Ran asked Lu Yan: "I asked you to help select some clever women from the base area to form a health team, how did you do it?" It doesn't matter if you know how to be medical, we can teach slowly, the most important thing to be a health team member is to be careful and patient, of course, it is best to be healthy, after all, run around with the team, sometimes you have to help carry the stretcher, the physical condition is too poor, it is not good......"
