Chapter 20 Grandma Zhang enters the Grand View Garden (9) thermite

According to Liu Hou's idea, it is necessary to collect books from all over the world and compile them into masterpieces similar to the Yongle Dictionary or the Siku Quanshu. However, it is obviously too early to think about this issue, and it is a bit ambitious.

Not to mention how many literati it takes to compile such a Big Mac and how many years it takes, the collection of books alone is still in its infancy. The beautiful wish of collecting books from all over the world is not yet known to be completed by one percent.

In addition to the fact that some books cannot be found, and some books find the owner of the hiding place but refuses to give it up, another reason is that even if the master is willing to copy it for you, the time for this transcription is definitely not a year and a half to complete.

Although Liu Hou provided good brushes and paper for those who went to copy, after all, the book had to be copied stroke by stroke, and the process was very time-consuming. Copying books is not something that can be done by just finding a homeless person, and it must also have a certain cultural foundation, otherwise no matter how many people there are, it will be in vain.

At present, the literati who serve Liu Hou are also very limited, in the early stage, the whole world helped Liu Hou collect talents, and now the whole world helps Liu Hou collect books. Liu Hou also had to keep some of them as clerks to help manage the "Ministry of Industry", which limited the number of scribes sent out to collect books.

In other words, it is not easy to enrich the library's collection all at once, and the construction process will take at least several years or even more than ten years. Liu Hou was far-sighted and launched this huge cultural project when he was still young, looking forward to reaping the fruits of his adult life.

The collected books were first handed over to the well-educated scholars for proofreading, and then sent to the printing house for printing. The printed books will be returned to the original owner, a certain number will be arranged to be sent to the main high-level officials of the Shu Kingdom, a certain number will be sold to various countries, and the rest will be hidden in the library.

The number of books in each book is relatively large, and in addition to meeting the needs of this central library, it is also considered to open branches in the future.

In view of the fact that when the dynasty has changed, the victors like to set fires, and the representative figure is Xiang Yu, who burned the Afang Palace so that people will remember him two thousand years later. What's more, some rulers are brainless and bored, and they also like to set fire to their martial arts, and the famous one is Qin Shi Huang, who came to burn books and pit Confucianism.

Whatever their purpose, their actions objectively have the effect of setting civilization backwards. Therefore, after the library was built, Liu Hou specially carved a stone tablet and erected it in the hall of the library.

The theme of the stele is "War will not be destroyed", which mainly means that the books in this library are the crystallization of human wisdom and civilization, and are the common wealth of mankind. Anyone who destroys the books in this place for any reason is guilty of crimes against humanity and civilization, and everyone will be punished.

It is everyone's common responsibility to protect human civilization, and the books here belong to all mankind, not anyone's private property, anyone can come in and read the books here, absorb the wisdom of their predecessors, and inherit the achievements of human civilization.

Of course, Liu Hou's level of classical Chinese is so bad that he can't do this kind of vernacular writing, so he will tell Fei Yi the general meaning, let him polish it into a good article, and then sign his name - Liu Chan in a big way.

Signing his name also comes from his extreme confidence in his future, he is confident that he can become an emperor through the ages, and he is confident that he will be in awe, so that the latecomers will be in awe when they see his name, so as to deter the latecomers, so that they dare not take this library lightly. It can be seen that Liu Hou is actually a very narcissistic person.

Then they visited the school, which is free of charge, which Liu Hou calls compulsory education, and where all children of the "Ministry of Industry" can study. This school lasts for 6 years, and unlike later generations, it actually includes the concept of primary and secondary school in 6 years.

After graduating from the school, those with poor grades can enter major factories as apprentices and learn various vocational skills, which are similar in nature to vocational schools and technical schools in later generations.

Those with good grades have the opportunity to be admitted to major research institutes and become researchers of research institutes, which is equivalent to college students and graduate students in later generations.

It's not that Liu Hou's school is a package distribution system, it's just that people who graduate from the school are more sought-after, and in this place where there is a lack of talents, the professional background is naturally not worried about finding a job.

Of course, there are also some people who seek their own way out and choose not to work in the industry under Liu Hou's name, and Liu Hou does not force them, so they can go. However, in this era of respecting teachers and repaying gratitude, there are very few such people after all, and they all have special reasons.

While visiting Zuo Ci's real yàn room, Zuo Ci was preparing to make a chemical real yàn. Liu Hou was surprised to find that Zuo Ci actually planned to do a thermite reaction test.

In fact, when Liu Hou and his entourage entered Zuo Ci's real room, they happened to see Zuo Ci holding a torch and leaning on the test bench. On the test bench was a large piece of iron, on which some bright silver powder and some rust-colored powder were mixed together.

"What is this?" Liu Hou's question startled Zuo Ci, and he hurriedly raised the torch like an Olympic torchbearer and terminated the ignition ceremony.

"It's thermite, teacher...... Little boy, here you are. ”

"What? Thermite ...... "Liu Hou is speechless now, TMD, can this Zuo Ci really make a thermite?" How can it be? That's too sci-fi, isn't it?

Thermite is a mixture of aluminum powder and metal (mainly iron) oxide powder in a certain proportion, add oxidant to ignite when used, the reaction is intense, alumina and elemental iron (if ferric oxide is used) and release a large amount of heat, the temperature can reach about 2482C, which can melt the generated iron. This reaction is called thermite reaction.

It was invented in 1895 by the French chemist Gohlschmitt. The thermite reaction principle can be applied to production, e.g. to weld rails. This method is commonly used in industry to smelt refractory metals, such as vanadium, chromium, manganese, etc.

There are also countries where solid rocket fuel also uses the principle of thermite reaction. It is worth noting that the armor-piercing shells of anti-tank rocket artillery also use thermite to burn through the armor of the tank. It can be seen that although the formula of this thermite is simple, it is indeed not an ordinary cow b.

"That's right, little boy, some time ago, the prospecting team sent to Nan'an County (now Jiajiang County) in Qianwei County brought back some gray ore, which the locals call alum stone, and Poor Dao began to think it was limestone. Who knows, after calcination, what you get is not lime. ”

"Oh, can you still make aluminum?" Liu Hou's curiosity was aroused, and he had the impression that aluminum was not so easy to refine. Otherwise, there would not have been a period of time in history where aluminum was more expensive than silver.

"It's not me who refines it, it's the sky."

"What day? What exactly do you mean? Liu Hou was confused by him.

"Because what I got was not lime, I felt useless and ordered the slag to be poured out. Who knew that night there was a lot of wind and rain, thunder and lightning, and several thunderbolts struck the place where the slag was dumped. The next day, someone found something shining silver. ”

"Is that all right? That's a coincidence. It's storytelling, right? Zhang Xingcai couldn't help but say.

"Hehe, how else to say that the little boy is a person favored by God." Zuo Ci stroked his beard under his chin and said with a smile.

"It makes sense." Liu Hou thought to himself, "The nature of aluminum is too active, and it is difficult to refine it with general chemical methods. ”

"Wow, could it be that the God of Wealth has descended to earth and wants to give you silver?" Zhang Xingcai squinted at Liu Houdao.

"No, not silver, but more precious than silver. Later, Poor Dao asked people to collect these glittering things and take a look, it was a silver metal, very light, not like silver. Its hardness is harder than that of tin, and after thinking about it, Poor Dao remembered that the master had talked about the thermite reaction, and wondered if it was aluminum, so he took some rust powder and wanted to try it. ”

"What? What reaction? Who is your master, and how can he even know such a magical thing? Zhang Xingcai showed an interested look.

Liu Hou glared at Zuo Ci fiercely, meaning to let him pay attention, not to mention leaking his mouth, and helping the relationship between the two.

Zuo Ci laughed twice, showed an embarrassed expression, and said, "My master, he is a genius, he has been very smart since he was a child, omniscient, omnipotent, and a fairy-like character. ”

Zhang Xingcai's eyes lit up: "Then can you take me to see him?" ”

"Not good!" Zuo Ci hurriedly waved his hand and refused.

"Don't be so stingy......" Zhang Xingcai began to use her signature coquettish moves.

"It's not that I won't take you to see him, it's that I can't find him." Seeing that the situation was not good, Zuo Ci hurriedly added, and successfully interrupted Zhang Xingcai's follow-up moves.

"Why can't you find him? Could it be that he died. ”

"No, no, the master is a man among the gods, where can he die so easily. But the master has traveled all over the world, and I haven't seen him for many years. The next time I see him, I will definitely take you to meet him. Zuo Ci wiped the cold sweat from his forehead and said.

Liu Hou gave him a look and secretly made a gesture, which means: "Okay, you magic stick, you have finally returned to your old business and started your old business, and you even deceived the little girl." ”

Zuo Ci peeked at Liu Hou, sweating coldly, and said to Zhang Xingcai: "Okay, let's not talk about this, let's talk about this new metal, Nuo, it's the one next to it." That's all there is left. Zuo Ci had no choice but to change the subject.

"Hey, isn't that silver?" Zhang Xingcai picked up an irregular silver metal block about the size of a fist on the real stage, and said, "No, why is it so light, such a large piece of silver should be very heavy." What the hell is this? ”

Seeing that he had successfully changed the topic, Zuo Ci couldn't help but breathe a sigh of relief, and hurriedly said: "This is the piece of metal that was split by lightning, if I am not mistaken, it is aluminum." It's a metal we've never seen before. ”

"It's not silver, what's the use." Saying that, Zhang Xingcai threw down the aluminum ingot, and it seemed that she had completely lost interest in such a historic event as the discovery of a new metal. “

"What is the use of this Rausch and what kind of medicine, it depends on how much you attach importance to it." Zhang Xingcai asked Zuo Ci again.

"Huh." Zuo Ci touched his beard and said proudly: "This is called thermite, the little girl can remember, according to the poor Taoist master, it can produce a high temperature that can melt steel in an instant." ”

"Who are you fooling, you think it's Samadhi True Fire. Although I have never made iron, I have seen the master of the craftsman's camp make iron, and those iron lumps have to be burned for half a day to soften them, and it takes a lot of effort to melt them. ”

Before arriving in Chengdu, Zhang Xingcai saw Liu Hou running to the craftsman camp, and sometimes she was curious, so she followed him to open her eyes, so she still had some understanding of these things, it was rare that she was so young at the time, but she still remembered.

"Hehe, Samadhi is really hot, well described. My master is such a strange person! You can even get something comparable to the real fire of Samadhi. Zuo Ci sighed and secretly glanced at Liu Hou again.

"What kind of samadhi real fire, but it's only two or three thousand degrees, and you haven't seen a higher temperature." Liu Hou despised the old way in his heart, but his face didn't show anything, and he took the trouble to fall on the face of his nominal master in front of outsiders.

"Is it that powerful?" As he spoke, Zhang Xingcai snatched the torch from Zuo Ci's hand and prepared to light the fire.

"Wait!" Liu Hou held Zhang Xingcai's hand holding the torch with one hand and shouted.

"What's wrong? Little Adou, do you want to try it too? Zhang Xingcai turned his head to Liu Hou and asked.

Liu Hou ignored her and said to Zuo Ci: "Old Dao, you just said that this thing can release a temperature that is enough to melt steel. Then you ...... test bed?"

"This test bench ......" Zuo Ci looked at Liu Hou in confusion and then at the test bench, only to see that the test bench made of granite was polished as smooth as a mirror, which was almost recognizable. After watching it for a long time, I didn't see any problems.

Liu Hou was speechless and said: "With such a high temperature, and the molten iron will flow later, you are not afraid that the test bench will be burned out." ”

Alas, this old way, I know that when I do experiments, I don't think about anything else, and I don't want to think about how much manpower and material resources it takes to polish such a large piece of granite. Liu Hou sighed in his heart.

"Oh, yes, yes. Then we ......" Zuo Ci hurriedly agreed, but turned his gaze to Liu Hou with an inquiring expression.

Dizzy, how can this cowhide lantern be compared with Zhang Fei, Liu Hou couldn't, so he had to point it out to him: "Let's go outside, find a place in the field and light a fire." ”

"Oh, yes, yes. Let's go outside. Lao Tao agreed.

Liu Hou rolled his eyes and walked out first.
