Chapter 95: chemistry lab

　　 "Because of this, this king wants you to build a cavalry. At least for now, the best way to deal with the cavalry is the cavalry."
　　 In history, the cavalry was not eliminated until the emergence of the mechanized corps. Therefore, in Xiao Ming's view, the army still needs to focus on building the cavalry unit for a long time.
Lu Fei nodded. No matter how good the infantry battle formation is, it can only passively defend, while the cavalry is an offensive force, a must for agility, assault, and pursuit. He said: "If this is the case, this thousand There are still a few war horses."
　　 "I understand that next this king is going to smuggle horses from the grassland and try to build a qualified cavalry." Xiao Ming frowned.
　　 Even in the age of firearms, the cavalry is irreplaceable.
　　 "Smuggling?" Lu Fei was taken aback, and then he said, "Doesn't your Highness know that the barbarians now prohibit the grassland tribe from selling war horses to the Great Yu Kingdom?"
　　 "Of course I know, otherwise it's not called smuggling, but trade." Xiao Ming said.
Lu Fei touched the back of his head, then looked solemnly, and said to Xiao Ming: "His Royal Highness, the Barbarians suddenly tightened the trading of war horses. This is not good news. In the past, this meant that the Barbarians had to use troops against Great Yu. "
"This is also what I am worried about, so this time I plan to buy a batch of war horses even at a high price." Xiao Ming said: "Moreover, the city wall of Cangzhou City should be overhauled. When the slaves donated by these merchants come, I will prepare. Let them rebuild Cangzhou City and build Cangzhou City into an insurmountable fortress for the barbarians."
　　 Lu Fei was excited, "Your Highness is going to use cement this time?"
　　 Xiao Ming nodded, "Yes, it's time to strengthen the fragile walls of Cangzhou City."
　　 After talking about this, Xiao Ming and Lu Fei talked about the new army of other states. These new army are currently led by the backbone of the Qingzhou army, and no rich people are involved.
　　 And every army has a long history in place, responsible for the ideological work of the army.
Speaking of the long history in the army, Lu Fei looked bitter, "His Royal Highness, these long-history troops must insist on their allegiance to Your Highness, shut up and ask the army to stick to the leadership of His Highness, and also propose eight honors and eight shame Yes, it's quite possible."
　　 "What? Is there a problem with the army's loyalty to this king?" Xiao Ming glanced at Lu Fei obliquely, thinking that if your kid has a double heart, you still have to kill you.
Lu Fei suddenly sweated on his forehead. He was just straight-hearted and displeased with the appearance of these literati mothers-in-laws, but he didn't expect to say something wrong. When he reacted, he immediately bowed and said: "Your Majesty, don't blame it, the end will be a big mouth Son, I'm used to talking nonsense."
　　 "It's pretty much the same. I don't care about it. The king who wants to equip me will try my best to satisfy you, but you have to be sober about the principle." Xiao Ming's words immediately became a set of training history.
　　 Those long-time candidates, Xiao Ming, naturally wouldn’t let them take the post easily, but let them take the post after the training, and they must pass the exam before taking the post.
　　 The content of this test is the guiding ideology of these troops. His purpose is to control the army. In this chaotic world, in this era, the army is easy to be tied by the generals and can only be strengthened by this method.
　　 Otherwise, there will be a rebellion in this state, and a mutiny in that state will be enough for him to drink a pot.
　　 "Don't dare, don't dare, even if you have ten courage in the end," Lu Fei said.
　　 Xiao Ming nodded, "I know you must be annoying long history, but you just don’t see it. Military long history will not interfere with you."
　　 "Yes, Your Highness."
　　 Lu Fei wiped his cold sweat, and saw that Xiao Ming was about to leave, and personally sent Xiao Ming outside the barracks.
　　Looking at Xiao Ming's departure, Lu Fei breathed a sigh of relief. In his opinion, the current King Qi was getting more and more evil, but he had to admit that his trick was powerful.
　　 Many soldiers didn't know who King Qi was before. Now this long history remains in the army, and King Qi is in his ears almost every day.
　　In his opinion, this is not a bad thing, so that the military of the six states can be stable, and there will be no situation in which the army of the rich family of Cangzhou City controls the city.
　　 Here, Xiao Ming left the barracks and went to Bowen Academy, where the newspaper company Fan Zeng is now in charge, collecting information every day, and publishing a new round of newspapers the next day.
　　 Now that the papermaking workshop and imitation printing have moved into the workshop area, Fan Zeng only needs to send someone to contact directly.
　　 Xiao Ming taught Fan Zeng how to do it. He doesn't need to do this small matter personally, he only needs to review the manuscript every day.
　　 After all, with the increase of various affairs, his daily government affairs also increased.
　　Industry must be managed, commerce must be managed, and agriculture must also be managed. It is necessary to be serious about doing industry and farming.
　　 Thinking all the way, Xiao Ming arrived at Bowen College. He didn't come here to find Fan Zeng, but to do daily teaching.
　　 In his free time on weekdays, he spends almost all of his time in the Bowen Academy.
　　The training of long history, the shipbuilding affairs of Zhang Liang and others, the technical problems of Chen Qi's equipment department, and the chemical knowledge of Lu Tong.
　　 This time he came for a chemical experiment. After the glass was produced, he asked the workshop to make a batch of chemical instruments for him. Now these instruments are in the laboratory. UU reading www.uukanshu. com
　　 Today, the basic chemistry knowledge of Lu Tong and others is basically no problem, the periodic table of the elements is very familiar, and the chemical formulas and the like are also sloppy.
　　 In theory, there is, but the specific practice can be realized by relying on these chemical instruments.
　　 When we arrived at the laboratory, more than two hundred people including Lu Tong were waiting in the laboratory. When Xiao Ming came over, he respectfully called "Your Highness."
　　 This chemistry laboratory is almost based on a modern layout. Below is a table of five people on which there are experimental instruments.
　　 Xiao Ming stood on it, and he also had his own set of instruments.
　　 This time Xiao Ming will teach them the method of producing sulfuric acid. The three acids and two bases have been the basic chemical industry Xiao Ming wants to achieve. The three acids are wrapped with nitric acid, sulfuric acid, and hydrochloric acid. The two bases are sodium hydroxide and sodium carbonate.
　　Combining the existing conditions of this era, he thinks the easiest thing to achieve is to make sulfuric acid.
　　 Because there was a saying of green alum oil in ancient times, and this green alum oil is sulfuric acid, and it needs green alum, water, and high temperature to prepare it.
　　In the information of the technological spar, there are some green alumites distributed on his fief, that is, modern ferrous sulfate, which is green in color. These green alumites are often the accompanying ore of iron ore.
　　 Qian Dafu discovered these green alums while mining iron ore, so Xiao Ming felt that these green alums should not be wasted and it was better to use them to prepare sulfuric acid.
　　 After all, sulfuric acid is widely used in the industry. One of them is pickling and rust removal, which can extend the life of machinery. Sulfuric acid is a solvent for metal purification.
　　 With sulfuric acid, he can purify some rare metals and lay the foundation for the alloy.
