The bad emperor of Tang Dynasty

It was so fast to return to Chang'an, since Guo Nuan named Guo Xiang to her daughter, three days passed in a blink of an eye, and during these three days, the princess mansion has been continuously visited by many guests.

Rarely free, Guo Nuan ran to the Weishui River in the south of the city. Alchemist Abu was busy instructing dozens of apprentices in the chemical workshop to smelt metal. He did not expect his old friend Guo Nuan to come back. It was a surprise.

Speaking of Guo Nuan, it has been half a year since Guo Nuan left. In the past six months, the chemical plant managed by Abu and the new chemical technology school have made great progress.

Since the production of explosives has been increasing steadily for more than half a year, half of the more than 30 taels of silver profits produced by the workshop every month are attributed to Guo Nuan.However, Guo Nuan didn't have many places to spend money for the time being, so he attributed the benefits of the chemical workshop to Shengping before he took office in Leizhou.

Now four chemical plants have been opened, and the school has recruited more than 300 students. These students selected from the farm children are very diligent, and all of them are quick to accept modern chemical knowledge. Now there are two batches of 60 students who have graduated. They all worked in chemical workshops.

Abu also told Guo Nuan a piece of news that stunned him.Among the seven or eight apprentices trained in the first batch of chemical workshops, Abu discovered a chemical genius.

This is a 17-year-old farm boy. He is very interested in chemistry and studies hard. He spends all day in the laboratory playing with chemical preparations and glass bottles. The oxidized ore was tossed and calcined in the furnace. Since there were a lot of diatomaceous earth that stabilized nitroglycerin in the laboratory, the apprentice also added a lump.

"At that time, after calcination, it turned into a grayish-white powder. The apprentice fiddled with it casually and didn't care at first. He thought the powder was a useless failure, and soon dumped it as garbage in the drain of the laboratory. "

Abu chuckled, spread his hands and continued: "The next day, the apprentice accidentally saw that a large amount of powder in the wet water channel had formed an extremely hard lump."

"Huh? Diatomaceous earth plus oxides, maybe clay is more suitable, quack, I didn't expect you toss out the rough cement." Guo Nuan couldn't help but sigh.

"Well, this apprentice and I spent two months continuously improving the composition, adding clay and lime slurry, and the effect of coagulation was greatly enhanced, haha."

Abu was a little surprised when he heard the word cement mentioned by Guo Nuan casually. The rough product that the apprentice made at the beginning was accidentally found in a water channel for its special purpose. The gray powder was mixed with water to condense into a block, so Abu decided to use it. An appropriate name to name this new product - cement

"Uh, but how do you know it's called cement? Dear Guo?" Abu was a little puzzled at the time.

Due to the unintentional invention of concrete, this product was quickly recognized and praised by the chief inspector in charge of palace construction.

Recently, the new concrete developed by the workshop using silicate has been sold to Jiangzuo Supervisory Office. The cement has replaced the earth-made clay made by mixing glutinous rice slurry with lime slurry and egg whites, which greatly improved the shortcomings of the insufficient strength of the earth-based concrete.

Abu said that with the invention of cement, it is estimated that it can be applied to buildings in the future, and maybe the buildings in the future will be built stronger and taller.

Hearing Abu's vision for the future, Guo Nuan sighed inwardly.The ingenuity of ancient people is no less than that of modern people. As long as they are guided to the threshold of modern technology and given a chemical path for them, then they can go farther and farther independently. The role of the guide of "Master introduces the door, practice depends on oneself".For example, the invention of the cement concept has nothing to do with Guo Nuan himself.

Guo Nuan couldn't help but put his thoughts into the future. Perhaps the extremely small amount of chemical knowledge he brought from modern times unintentionally, like sparks, was created with the thinking of ancient people in the open-minded era of the Tang Dynasty... It can start a revolution that subverts the technology of the times The sea of ​​flames of the revolution... What a brilliant and surging pioneering work should it be?Guo Nuan pondered.

From chemical industry to the gate of science and technology in the new century, let’s deduce it according to the materialist philosophy. Guo Nuan feels that the liberation and development of creativity in a scientific and technological discipline are broken through points and connected into lines.

Quack, Guo Nuan's heart twitched violently. He didn't dare to continue to speculate on the future evolution of industrial civilization, because it took only two or three hundred years for modern industrial civilization to mature.

"Quack, with this evolution, will the birth time of modern science and technology be rewritten in history? Industrial civilization will be shortened by 1000 years and come earlier?"

After visiting Abu, Guo Nuan specially suggested that he promote the knowledge of chemical engineering. The principal of the Imperial College, Mr. Chang Gun Jijiu, visited Guo Nuan in a hurry the day before yesterday.

When the smiling old Chang went to the house to bring a few jars of good Western Region wine to find Guo Nuan, Chang Gun discussed with him whether to add a special subject of "Chemistry" in the Imperial College.

Guo Nuan was really surprised at the beginning, Chang Dun took the initiative to visit and asked to add chemistry subjects in Taiyuan College?But after a little thought, he figured it out.

"Quack, brother Chang, haven't you seen the sweetness of the education in the chemical engineering school under my brother's name recently?" Guo Nuan joked happily.

At that time, Chang Dun awkwardly laughed: "Yes, the power of this 'technology' is really powerful, you see, the three-bedroom concubines in my brother's house are all using the creams, moisturizers and so on produced in your workshop , Just because of the small bottle of limited-edition cosmetics you launched, the three women at home are arguing to the death every day, hey, the sky is about to be overthrown."

"Also, like the nitroglycerin explosives purchased by the Ministry of Industry, it should be because of its powerful power that it helps to dig rivers and canals. This year's Weishui farmland canal project saved a total of 12 corvee labor, and also shortened the time by more than half. This" Chemical industry" is practical knowledge that benefits the country and the people, and can create many practical things."

Guo Nuan repeatedly nodded in agreement with Chang Gun's repeated sighs.He is worthy of being the leader of the country's highest institution, Guo Nuan also agreed with what he said when he came to visit that day.

Damn, this Tang Dynasty person really has a long-term vision and an open-minded and wise mind. Compared with other feudal old antiques, he is [-] times more capable of accepting new ideas.Immediately cited him as a confidant on the road of modern technology.

For the hypocritical Minister of Education, Chang Gun, who brought a lot of good wine and was so polite to ask for help, Guo Nuan felt that the promotion of the discipline of material science would help improve the quality of the whole people, and chemical technology should not be used as a monopoly secret recipe for workshops to make money. , This is extremely narrow and short-sighted thinking.Why didn't Guo Nuan push the boat along, and he readily agreed.

After inspecting the chemical workshops, Guo Nuan decided to recommend Abu to Chang Dun when he met Chang Dun in a few days, and then Abu, as a lecturer of Taixueyuan, would be open to teach all students who are interested in chemistry at Taixueyuan. It is estimated that chemistry will flourish soon.

"Quack, brother has done a great thing that benefits the country and the people without any objection." Someone said to himself quite proudly.
