readx; In the afternoon of the same day, the needle and needle tube have been prepared, Zhou Jin found a dog, first checked the dog's hemoglobin concentration with bile alum is copper sulfate solution, and then gave it an intravenous injection of cyclosporine, and then waited for the drug reaction, one or two hours later, to see if the dog would hang up, and after three consecutive injections, then to observe the speed of the lower layer of blood. Pen, fun, pavilion www. biquge。 info

After Zhou Jin finished the injection, he began to refine the catalyst for the preparation of sulfuric acid. He first incorporated the already burned gangue into a diluted alum oil solution, which was actually a very low concentration of sulfuric acid. Then the soybean is distilled, the gas is passed through the water to obtain ammonia, the ammonia reacts with the alkali to obtain ammonium salt, and finally the ammonium salt is used to obtain the required catalyst. For a whole afternoon, Zhou Jin used a large vat to get more than 500 catties of cinder stone, and finally got half a catty of catalyst vanadium pentoxide.

The extraction of this thing means that the preparation of sulfuric acid is much simpler. The gas after the high-temperature reaction of pyrite can be heated by the catalyst into the sulfuric acid solution to obtain concentrated sulfuric acid. So I put my work on the table before dinner.

Since the kilns were in the open space to the west of the courtyard, and Zhou Jin was going to expand the garden, the workers would walk around the kilns, which was very unsafe, and after thinking about it, they had to fence off the open space and build some warehouses and places for the workers to stay.

By mid-March, Zhou Jin's garden had been built, and the kiln had been built like a factory, divided into a furnace area, a reaction area, a metallurgical area, and dormitories for more than 40 workers.

Li Xiuwen's glass business is also in full swing and has made a lot of money. Zhou Jin is actually not interested in making money from glass, and the sales of his glass business in various regions can bring him local news. In order to be safe and hidden, Zhou Jin's business model for Li Xiuwen is the franchise sales model, and he does not let Li Xiuwen open stores everywhere, but only sends people to establish a sales network and let local stores sell. This model brings back local news after each shipment. It's just that the time has been delayed by more than ten days.

Hundreds of thousands of catties of copper ore got one or two platinums, and Zhou Jin took out half of it to make them build a filter, but it was the size of a fist. Zhou Jin plans to consume oxygen in the air by combustion, then consume carbon dioxide through lime to obtain impure nitrogen, and then filter the coke oven gas with lime and then pass water to obtain impure hydrogen. Then, the iron oxide obtained after making sulfuric acid from pyrite catalyzes the reaction of hydrogen with nitrogen to obtain ammonia.

After ammonia enters the water, it is decomposed into ammonia to obtain relatively pure ammonia, and ammonia can be obtained by a series of reactions under the addition of platinum net at high temperature and high pressure. Because it is high temperature and high pressure, the reaction space will not be very large, just a one-liter dry pot porcelain box, and a thick layer of iron sheet on the outside. The pressure can only be pumped manually, but fortunately, the air pressure is no more than ten atmospheres at most, that is, it needs more than 20 catties of pressure at most.

And heating up to 900 degrees can only be estimated by workers according to the rate of heating. Replenishment of pressure can only estimate the gas loss based on the flow rate, which is then supplemented with dry air.

Three days later, the equipment was finally completed, and more than 100 catties of concentrated nitric acid could be obtained every day. All that's left is to use vegetable oil to get glycerol with sodium perhydroxide.

The sodium hydroxide only needs to be heated with soda ash and lime for about 100 degrees to obtain, and the process is not complicated.

With concentrated sulfuric acid, concentrated nitric acid, and glycerin, Zhou Jin finally combined**. But that day, I was so excited that I was so happy that I dropped it on the ground. Fortunately, due to the small amount, Zhou Jin was able to save his life and only lay in bed for more than half a month.

On this day, Zhou Jin called Zhou Hong over and asked Zhou Hong: "Zhou Hong, how much money do we have now?" ”

Zhou Hong thought for a while and said, "There are more than 20,000 taels of silver in total." ”

"It's already spent more than 30,000 taels? Where did Xiuwen not make money? ”

"Where has Xiuwen already spent more than five thousand taels. The young master spent a lot of money on copper and iron ore. Since it has to be transported from a distance, the cost is not small. ”

"You have to find a way to exchange those copper coins for money, see if they are minted into copper coins, you and Song Cheng discuss it. Iron ore still continue to buy, it is better to buy a mine, how to get me to find time to ask my father-in-law. There are also coal mines, you also find a way to buy one. If you can't buy it, check the mountains near Ruichang to see if there is any iron ore. ”

"There is an iron mine in Ruichang? Haven't heard of it? ”

"A few days ago, I read the notes of the ancients, saying that there is a yellow stone in the mountain, which can attract magnets. Most of those Yellowstones are the iron ore we want. You get a few people to investigate. It's best to dig a few holes and check them out. ”

After Zhou Hong went down, he called Song Cheng and Liu Quan. Zhou Jin began to let them build guns, and the mechanical corner was given to Liu Quan, and Song Cheng was in charge of forciling.

"Song Cheng, you not only have to make the barrel, but also the bullet, the bullet is a cartridge, loaded with gunpowder, and the front is a bullet, and the bullet is slightly larger than the barrel. So the warhead should be softer, you can mix lead and iron, you can try more specifically. ”

"Fourth Master, do we still need to fill gunpowder?" Song Cheng asked.

"No, the warhead and cartridge are built separately, and I will find someone else to install them. The size of the barrel and the size of the warhead, let Liu Quan tell you when the time comes. ”

After Song Cheng left, Zhou Jin said to Liu Quan: "This barrel is the same shape as the tube of our crossbow now. This time it was an iron pipe, so you had to find someone else to do the threading inside. If you need their forged cooperation, you can just let them do it, but you can't tell them what you want to do, understand? ”

"Understood."

"The army's muskets are lit and fired, but our gunpowder is different from theirs, and it only needs to be hit to trigger a burst. All you have to do is pull the trigger and the firing pin can hit the bullet hard, detonating the explosives inside and firing the warhead. ”

Song Cheng lowered his head and thought for a long time, and said, "Young Master, I still have to go back and think about it." ”

"Good. If you think about it, you just do it and improve it slowly. ”

After Song Cheng left, Zhou Jin asked Sun Gancai to call.

"Dry wood, you first find someone to synthesize nitrocellulose, that is, put the cotton in a mixture of concentrated sulfuric acid and concentrated nitric acid, take it out in a quarter and a half hours to get nitrocellulose, and then mix it with the explosives I made. It's much more stable that way. ”

"Fourth Master, that thing is too dangerous. What do I make it for? ”

"You don't have to ask, be careful to keep it confidential, and don't tell the workers how to do it."

After Sun Gancai left, safety came to mind again, so he immediately asked people to find Meng Changjiang and asked, "Zhongwei, how is the training?" ”

"After Sun Gongzi's training, his melee fighting ability has improved a lot. Moreover, Sun Gongzi also gave me a book of Qi Jiguang's soldiers, and under his guidance, I learned a lot of useful things. ”

"Oh, yes, you can refine some ideas and make them simple and useful, write them into words, and show them to me."

Meng Changjiang touched his head and said, "I can write." ”

"You just write what you think, you don't need any style, you just write it like talking."

"I'll give it a try."

"Well, I called you here to let you be on duty day and night according to the platoon of guards. It would be better to build some towers on the walls of our courtyard and watch them day and night. If you have enough people, you will continue to recruit. Also, after a while, your weapons will be replaced with muskets. Be prepared to change gear. ”

Meng Changjiang said: "Yes, I will think about this matter carefully." ”

After a while, Zhou Honghui came to the study again, and he brought some accounts over for Zhou Jin to check. Zhou Jin flipped through it a few times, but he couldn't see anything about this running account.

So he said, "Forget it." I won't look at this account. I forgot to explain it just now. Zhou Jin paused: "You find someone to keep an eye on the factory for me, it's all troublesome for the government to know about it." Especially Sun Gancai, he had to be monitored. Their families have moved. ”

"Recently, after the houses behind the courtyard were built, they have all moved over one after another."

"I'm going to have Zhongwei build towers around for defense, and I'll check on people coming in and out. You pay attention to cooperate with him. ”

"The little one knows the weight." Zhou Hong hesitated for a moment and said, "Fourth Master, we estimate that we will live here for the next two years, and now it is very peaceful, why do we want to get these explosives?" ”

Zhou Jin said with a solemn expression: "The world is not peaceful, not to mention that the last time I went to see those people, I had clearly told them that I would go to suppress the bandits." Those bandits have a reason not to strike first. ”

"Is the fourth master really going to suppress the bandits?"

"Yes, I already agreed to this before my father-in-law went to Nanchang. And if these guards have not been fought, they will be of no use at that time, and they must be trained. ”

Three days later, Zhou Jin tested the dog's hemoglobin concentration and found that it had really increased a lot. So after a fierce ideological struggle, he began to inject Huang Shuanghui.

After the injection tube was steamed for half a day, it was soaked in high alcohol for more than an hour before preparing to inject Huang Shuanghui. First of all, of course, I checked the hemoglobin concentration with bile alum solution, and found that after dropping a drop, the blood kept floating and sank in very small amounts. It took a lot of effort for Zhou Jin to find the veins, gently stroked them for a while and said, "Huihui, I don't dare to guarantee that this medicine is what I need, so ....."

"Fourth brother, I won't blame you."

Zhou Jin took a breath, and then decisively and gently inserted it, the blood vessel was too thin, Zhou Jin only inserted a little bit, and after it was stable, he began to inject. However, if the amount of two or three milliliters is two or three milliliters, Zhou Jin has been injected for a long time. When I pulled it out, I felt that my back was completely wet.

"Huan'er, in the future, this room should be washed frequently, the inside and outside of the cabinet should be cleaned, and the corner of the wall should be cleaned with very thin bile alum water when going to the workshop. I'll tell them that. ”

"Got it." Huan'er replied. She had already learned that the last opportunity to get a bed was given by this young lady, so it was better for Huang Shuanghui now.

"Don't let outsiders in this house. You also cut down on going in and out. ”

Li Minqi said: "Why? ”

"What I say, you just listen." Zhou Jin is colorful.

"If you want to replenish your blood, you still have to keep eating."

Zhao's mother replied, "I will remember." ”

Zhao's mother came into contact with a lot of flowers with people outside, and she could only enter the house after bathing, washing her hands and changing clothes. The same goes for everyone else. ”

Li Yu said: "Is it so serious? ”

"During this period, Hui Hui is susceptible to wind evil, so it must be like this."
