Nitric acid, nitric acid, hydrochloric acid, one is soda ash, caustic soda, lime is the basis of modern chemical industry, whether it is organic chemistry or inorganic chemistry is indispensable to these things. In particular, the organic industry is inseparable from nitric acid, nitric acid, and alkali. This alkali, because China lacks natural alkali ore, and the modern discovery of alkali ore such as the super-large alkali ore in Tongbai is eight or nine hundred meters underground, so Gao Pet has not yet had the technology to get them out. How much alkali can be trafficked from the West, and how much will it cost to transport it for nearly 10,000 miles? How much is it, so it is okay to do some small experiments with commercial alkali, but industrial production such as the production of soap, glass, paper, etc.

Therefore, Gao Pet must make his own alkali.

From modern times to modern times, there are several main types of soda ash production, one is the ammonia-alkali method (it has the Soxhlet alkali method and the Hou's alkali method) and the Lübulan method.

Although the ammonia-alkali method is good, Gao Pet is not able to produce synthetic ammonia, so it can only use the Lu Bran method, but Gao Pet takes into account the difficulties and costs of salt and sulfuric acid production, and directly omits the process of making sodium sulfate from salt, and directly uses miscanthus nitrate (sodium sulfate pentahydrate) for production. In addition to producing soda ash, the whole process also has sulfur as a by-product to make gunpowder.

Gao pet sorted out the technology of alkali making, including equipment drawings. He wants to hand it over to the third uncle and let him handle the opening and production of the factory. In addition, Gao Pet also handed over the boiler and steam engine technology, free forging and air hammer technology, and mineral processing technology and equipment to the third uncle, and the drawings and processes of these equipment took Gao Pet more than dozens of days.

When the third uncle came back, he brought thousands of people, most of whom were still skilled craftsmen, but the burden on the Gao family was very large, at least the current food and housing problems should be solved first. For this reason, the previous non-stop recruitment of nursing home helpers stopped first. Gao Pet asked these people who had trained themselves to organize training. The base has also been used. Most of the horses in the family also make training tools for the base. Now there are more than 3,000 people in the base, and we can build three battalions by then. However, the allocation of various units at all levels must be finalized, and according to the study of this period of time, the deployment plan for a battalion that was originally carried out should be further revised.

Archers and crossbowmen are the main force of the Song Dynasty infantry, so it should be appropriately increased, due to the improvement of crossbow technology, the use of three-stage continuous shooting tactics, can effectively make up for the lack of rate of fire. Melee has grenades. There are also certain means of melee defense, and archers can also be used as spearmen and shields in melee combat. Therefore, the spearmen and shield soldiers of the troops can be greatly reduced. The role of the Thunderbolt is obvious, and increasing its configuration as much as possible can effectively increase the output of firepower.

But a mobile rapid response and support force is what Gao Pet wants most, whether it is garrison defense or field warfare, if you don't get support, the infantry will be grinded to death by the cavalry, and when your bow and arrows are always used up, you will also run out of water and food. At the same time, if the battlefield enters a stalemate, the sudden rapid entry of a mobile force will play a key role in the progress of the battlefield. But this fast reaction force can only be cavalry under the current conditions. Gao Pet has no horses. How to get a horse is one of the main tasks of Gao Pet.

In addition, Gao Chong is also considering whether it is necessary to build a baggage and bridge engineering unit? Now, of course, there is no need for specialized troops, and if there is an organized, usually appropriate training, wouldn't it be very convenient to mobilize? In the expansion of troops can be supplemented in this.

In this war years, does the Gao family need militarized management? This needs to be discussed with the family.

Gao Pet thought of his gang of righteous brothers, they have been away from Ningguo for more than three months, Guan Yu and his party have been completely and cleanly assimilated by Gao Pet, and have become the hardcore of Gao Pet, Guan Lin has the opportunity to get to Gao Pet's side all day long, for Luo Xianling's daughter Luo Hanbing and little cousin Su Huilan, although they didn't say anything, but they did everything possible not to let them have more contact with Gao Pet, and it seems that she is not a big-chested girl.

The power of Ningguo should also be used, and it should also be discussed with Guan Yu, the eldest brother, about Ningguo. Gao Zhong asked Dazhu to call Guan Yu.

Guan Yu was wearing a military uniform, with dark skin and a half-inch head, and he didn't know when he cut his hair, and his height seemed to have grown, and he was more burly and strong. Walk into the room with a gust of wind.

"Fifth brother, is there something wrong with me?"

"That's right, your brothers have been here in Tongling for more than three months, and you still ran out of your house secretly, although you have notified your family here. But it's inevitable that they're a little homesick, and I don't know if any of your brothers are going to go home and see it. ”

"Of course, the training of the troops here mainly depends on a few brothers to help me, and I can't do without you for a while. It's not good to walk together, do you want to go back in batches to see? ”

"Fifth brother, they have only been out for a few months, so there are so many words, and they haven't learned the little things you taught yet, so they are qualified to be homesick and bitter? As far as you said, at least there must be a life-saving kung fu, and besides, our troops have just started training. No, I'm not going home, and neither can they, so let's talk about it then. ”

Guan Yu is very serious. It's true that it's very hard to practice every day like this, and it's a double world with the life of the former molecular brother, but after learning so many things, let's just say that this three-stage attack, continuous firepower output, if the enemy's horse team impacts, it is enough for them to drink a pot, starting from the ultra-long-range attack of the thunderbolt, to the long-range projectile attack, to the direct aim shooting in the back, and finally adding a round of grenades to be alive to rush to the front, it really needs to be studied and studied. In that melee triangle stabbing tactic, comrades defend and attack each other, and win more and less locally. Guan Yu thought a lot, the most right thing he did in the past seventeen years was to run out of the house, otherwise how could he know the fifth brother.

"Big brother, either like this, you see if it's okay, just go back to Ningguo with me, one is that Guan Lin's matter is always evaded and not always solved, just say something. You are also a big brother, and this is also an attitude for the happiness of your little sister, but isn't the way a little negative? In addition, big brother, you also know that I still have a lot of technology here that can help your family with some things. For example, I also discussed this technology with my family to you, so that your family can send someone to learn it, and you have a paper mill at home, and the historian also prints books, I have very advanced papermaking and printing technology to make this business bigger, and now there is a kind of sugar cane in the south that can make sugar sweeter than caramel sugar, and this sugar technology can also be given to you, and you have a good relationship, and you can build a company like China Huanyu together. ”

Seeing Guan Yu look at him with that strange gaze again, Gao Zhong said:

"You must wonder why I did this, one is the lack of energy of the Gao family, and the other is that you are not my brothers, why can't everyone share what I have. On the other hand, I also want to go with you and also want to go to Ningguo to see, what we can also use, for example, you have a lot of pine trees in the mountains, you can collect rosin, this is a big thing, you also have sumac trees. In short, in order to go to your Ningguo, I have made considerable preparations some time ago, and I am also tired during this time in Tongling, so let my eldest brother accompany me to relax. ”

"The fifth brother went to Ningguo to let the eldest brother accompany him, the eldest brother is asking for it, we have a lot of fun and delicious things in Ningguo, which will definitely make the fifth brother happy and satisfied." Guan Yu was a little excited, and a little incoherent. Said a lot of good things to eat and fun places to play.

"Then let's settle it like this, the brothers called together in the evening and told them about the plan, Guan Lin's matter, whether to go back together or stay here, you can handle this matter yourself. Let's prepare, get ready for us to go. I want to bring some things to bring, you also bring some Tongling specialties back, do you know Tongling's specialties, the best specialty of Tongling is beauty, I think my Huilan is good!. ”

Especially Su Huilan, the daughter of the second uncle, they are quite speculative. Guan Yu heard Gao Zhong say his thoughts, and his face turned red all of a sudden.

"Then you treat women as a specialty." After that, I went to Zhang Luo's evening association.

During this time, the brothers were busy training, and Gao Pet was even busier, and said that Gao Pet was going to see it every other day, but he had not reunited, and in later generations, there was a Sunday, and he also had a two-day rest system, this Da Song was not so good, although Gao Pet knew, but the pressure in his heart was very great, and he gritted his teeth and only gave a month off for a day, which can be divided into two half-days off, and he can go back to see his family.

But his brother still has to take care of it, take advantage of this opportunity, call his brother in the evening and let them relax. After eating and drinking, everyone had nothing to say about Gao Pet's plan, thinking about how to share the pressure of the fifth brother.

Guan Lin also soaked in the training ground every day, and the people also tanned a lot, and when it came to returning to Ningguo, his head was like a drum, but he refused to go back to Ningguo. Guan Yu said all the good things, and Gao Pet also did a lot of work.

She only asked, "Can you promise to let me come back when I go back?" ”

Guan Yu has no words, and Gao Chong can't guarantee it, who can guarantee that she is you?

Guan Lin was afraid that she wouldn't be able to come back. She had an idea in her mind.

This preparation lasted five days, and after five days, Gao Zhong took more than 20 people, all carrying crossbows covered with cloth bags, some carrying spears, and some with large knives at their waists. There are more than 30 wheelbarrows, pulling gifts such as liquor, as well as goods transported by the car dealership, and the head car has a sign flag of the Gaojia car dealership. There were a total of forty or fifty people in Gao Chong's party and the car dealership.

Before leaving, Gao Chong's mother called Guan Yu Guan Lin, said a word, gave some gifts, asked him to say hello to his family, and brought a message to Shi, Li, and Sun's family so that they would have time to come to Tongling.

Many people came to say goodbye, and Gao Chong also saw Luo Xianling's daughter Han Bing and his little cousin Su Huilan in the crowd, but somehow, Han Bing didn't come forward to speak.

Gao Chong and Guan Yu are both riding horses, today Gao Chong is wearing a set of soft leather armor, carrying a chiseled gold tiger head gun, majestic, Yan Ran is a general, but Guan Yu is very special to carry a son's hat, a white robe, very handsome and chic.

Everyone said goodbye to everyone and waved their hands on the road.
