Datang Library

Bai Fan took Li Chun to Yuan Tiangang's Taoist temple very quickly, and asked him for a group of Taoist disciples who were proficient in alchemy. Of course, this group of people had given up alchemy, and they all followed Bai Fan. Yuan Tiangang's Taoism, researching basic chemistry, now Bai Fan took him away and directly assigned it to the first class of Mr. Academy, and started researching new materials with Li Chun.

This new material is actually what can be called the world's number one building material - cement!

"In short, is this thing really so miraculous? Ordinarily it looks like earth, but water turns it into stone? How does this feel like the legend that the earth turns into steel?" Li Chun couldn't believe it.

Bai Fan explained: "It's not so magical. This thing is taken from the stone. The basic principle is to burn the stone with fire, and turn the stone into ashes, which is easy to transport. We then mix it with water, which is equivalent to getting stones from fire." .

It’s just that the internal reaction is extremely complicated, and these are things that Taoists need to study and consider. You just need to understand the performance, hardness and tolerance of this thing, and help you taste the pros and cons. "

"It's true. My favorite is blueprints and mechanics. These strange symbols and the like. I'm getting old and I can't do what I want. My apprentice Chengxun may have the patience to learn this." Li Chun said modestly.

...Bai Fan's belly, what do you mean you are old, you old guy can eat three roast chickens a day, verify two hundred blueprints without sleep for three days, it can be said that he is the most energetic besides the medicine king Sun Simiao Old man, so humble now.

It took two days, Bai Fan and the others worked together to build a kiln for firing cement by the local method. A group of people were disgraced, and they all surrounded the kiln and watched the situation inside.

Chapter 453 The Cement Comes Out, Princess Silla Comes

"Uncle Bai, why do we need to find gypsum to add to this thing? Gypsum is a medicinal material!" A young Taoist asked Bai Fan humbly.

This person's name is Qingshi, who was originally a Taoist boy in Laojunguan. Later, because he was obsessed with alchemy, he was sent by Yuan Tiangang to Baopuzi's lineage to learn alchemy. Everyone in the same branch thought that Bai Fan had obtained the true biography, and they took the initiative to join Bai Fan's family, so Bai Fan took advantage of the situation and selected a group of potential chemists from among them.

Leaving behind a group of those who like to make medicines to learn the real alchemy of pharmaceuticals. Except for the recognized Taoist pharmacists, those alchemists who refine Jindanhong pills have been strictly prohibited by Taoism.

"Nephew Qingshi, the avenues are interlinked, and medicines need medicine primers, not to mention refining cement. We need to grind limestone, clay, and iron ore powder into powder. After mixing the three, they can't be combined into cement. This gypsum is just a medicine. Citing, without gypsum, cement cannot be refined." Bai Fan patiently explained.

The outsider next to him, Li Chun, asked puzzledly, "Why does this kiln need eight air boxes? The temperature in this kiln may melt everything."

"This is not high, only 20 Baidu, but this is already the limit of our current conditions. I want Datang to create a flame like the sun within [-] years." Bai Fan looked forward to it.

Li Chun laughed loudly, "Jane, you are ridiculous, why does it take 20 years for a flame like the sun? The flames lit by waving hands are probably hotter than the sun."

……

A group of Taoist chemists looked at Li Chun as if they were looking at an idiot. He was the only one who laughed, and the others didn't laugh. Gradually, Li Chun felt that something was wrong. What's wrong?Is it embarrassing if no one cooperates?

"Well, Master Li, my uncle taught me that the sun is a big fireball, which is very far away from us. When the fireball hits us, there is almost no heat, but the sun itself is about 5000 degrees. A temperature at which humans can be burned before approaching." Qingshi explained.

Li Chun's laughter stopped abruptly, and he coughed twice, "Joke, it was just a joke, look quickly, has the cement burned?"

Bai Fan opened his eyes and saw that the temperature of the furnace had reached [-] degrees, and it was time for the reaction to occur. Since it was only in the experimental stage, there were not many raw materials put in. After a while, it was estimated that the firing had been completed. Fan ordered to stop the kiln, waited for the furnace to cool down, and personally stepped forward to take out the finished product.

There are not many things, only a basket of finished products. Looking at the color, Bai Fan frowned slightly, and looked at it with the eye of a ruler. The cement was burnt, but it was extremely rough, with only two hundred marks, which could only be used for building houses, not for To build a bridge, it takes at least five hundred marks to build a bridge.

If it weren't for Bai Fan's eye for rulers and moments, the grade of cement would have to be tested after mixing the mortar for 28 days. Now with Bai Fan's four-level gift bag plug-in, it greatly saves time for the development of cement.

"This thing is indeed cement, but the production is too rough and the quality is not very good. It can only be used to make houses, and it is far from what is needed to make bridges.

Lao Li, here it is, the thing is made, you have the final say on how to use it, if you want something, you can just ask these boys, when they can develop what they need to build a bridge, you have to give them a drink to celebrate. "

Bai Fan grabbed the wooden basket in his hand and handed it to Li Chun. Li Chun hugged it quickly and looked after the first basket of cement like his own child. He wanted to take it back and try it out. Hard as a rock afterwards?

After making cement, he took out relevant books and left them to a few Taoist priests. Bai Fan went back to the academy. The fourth floor of the library was open, so the library of Zhongnan Academy had to be built up. In the past, it was made of wood. The structure, now that there is cement, needs to be overturned and refurbished, all of which are made of reinforced concrete. As for the production of Datang Iron and Steel, Bai Fan is going to build an iron-making blast furnace.

"Lan Tianhou is really a busy man, so it's easy for the little girl to find her."

Before he reached the principal's courtyard, a woman's voice sounded not far away. Bai Fan looked up. Isn't this Princess Jindeman of Silla?What is she here for?

"Busy people can't tell, it's just that there are more trivial matters.

There is no official title in the academy, the princess should call me Dean Bai. "Bai Fan laughed.

"Kindman has met Dean Bai!"

"Girl, please!"

He brought Kinderman to the small courtyard and finished it on the stone table. Bai Fan made the tea himself, and then asked: "The princess is not chasing after our emperor, why do you come to me as a teacher?"

This is what Bai Fan doesn't understand. Before, he conspired to marry her to the emperor. It was a very good choice, and the other party seemed to agree, but why hasn't it succeeded after so long?

Kinderman smiled wryly and said: "It's God's will, I am very interested in the singing and dancing of Datang Entertainment City. I practice hard every day and want to perform for His Majesty the Emperor, but I finally waited for him that day, but who knows that he is on the way halfway?" Met a very beautiful woman, since then there is no one else in his eyes.

That woman is Zheng Liwan from the Zheng family, so this matter has not been completed.

I thought I would have a chance if the emperor stopped pestering Zheng Liwan after your dean Bai made a move. Who knew that I took the initiative to go to the palace to ask for an audience.With the willow-like posture of the little girl, there is no hope of marrying the emperor. "

...Bai Fan was speechless, but his heart was like a bright mirror. This princess of Silla was unparalleled in beauty. When she first came to Datang, Li Er was indeed tempted and wanted to match her own. At that time, Kinderman He promised to take a look first.

Now it seems that Kinderman was too ostentatious, hesitated for a long time, and missed a good opportunity. The first time he was cut off by Zheng Liwan in the entertainment city, and the second time he entered the palace, he met the eldest grandson Empress who was pregnant. Now Li Er wants to please his wife , how could it give her a good face?

"This...it's really your bad luck, so what are you going to do? You don't come here to ask me to help, do you? I really can't help with the love between men and women." Bai Fan said awkwardly.

"Why don't I marry you? My father was rescued by you. Didn't Datang say that he would repay his kindness with his body? You are younger than the emperor and have the same ability as him. The most important thing is you Without a harem, you are more suitable for me than he looks." Kinderman said seriously.

"...Don't be joking. I feel that I have no way to separate the four girls in my family. I will never marry again. It's okay not to marry the emperor. You can look at other unmarried princes. There are many princes of the Tang Dynasty. I am worthy of you." Bai Fan suggested.

"The emperor doesn't like me, don't you think so?" Kinderman stared at Bai Fan with big eyes and asked.

Shaking his head, Bai Fan retorted: "You and I are friends, you are so beautiful, who would look down on you, but our friendship has nothing to do with anything else, I think it is very pure, I am not your good match, don't serious."

Kinderman smiled and looked at the other party's earnest explanation. He was really cute. He stopped joking and said seriously: "Since you and I are friends, then I have something to ask. I have a younger sister who is 12 years old. It is the right age to go to school, I want her to enroll in Zhongnan Academy, you, the dean, are my friends, I wonder if you can open the door of convenience?"

Chapter 454 How to Solve the Dilemma

The question of Princess Silla really stumped Bai Fan. It was famously said at the entrance of the academy before that Zhongnan Academy only accepts people from the Tang Dynasty and does not accept foreigners, but this Silla is different. The whole country is attached to the Tang Dynasty, but Goguryeo has not yet settled down and has not completely controlled the territory.

Now Silla is actually considered a native of the Tang Dynasty, and accepting her sister by himself is not a violation of the rules.

"What? You said that the academy doesn't accept foreigners, but the whole country of Silla has defected to Datang, and my father's family and I have all moved to Datang. Don't you think we are aliens? If you join Datang, you will be discriminated against. Don't you think Datang is a bit too much?" Kinderman said dissatisfied.

Bai Fan's hesitation is not because he can't distinguish the identity of Silla now, but because he is worried about hidden dangers in the future. According to his original idea, after the Tang Dynasty ruled the world in the future, it is inevitable that the academy will accept foreign students, but that will have to wait until after the Five Dynasties. The assimilation is the only way to do it, and the foreign race that has just joined must not be accepted. What if the whole clan rebels in the future after learning the knowledge of the academy?

Having figured this out, Bai Fan shook his head firmly: "You and I have a good personal relationship. Let me tell you the truth. The saying that Zhongnan Academy does not accept foreigners will be broken in the future, but not now. We need to wait until Datang completely accepts it." Only when the surrounding countries complete the unification, then the whole world will be Tang Dynasty people, so naturally the Academy will no longer say this.”

"Then why not now? Isn't Silla from Tang Dynasty?"

"No, listen to me. You are not an ordinary princess. You have experienced political experience. Zhongnan Academy is too important. The knowledge here cannot be leaked casually. Students who enter the school must go to the five generations of investigations. .

Once someone acquires knowledge and seeks refuge with a foreign race, it will be a catastrophe, so in order to avoid hidden dangers, even if the surrounding area is attached to the Tang Dynasty in the future, we will not accept those people until they have become good citizens of the Tang Dynasty for five generations. child.

The first generation of children will not be accepted, because they are afraid that these children will remember the different races and regenerate a rebellious heart in the future. "Bai Fan explained to the other party seriously.

But Kinderman didn't appreciate it, and said coldly: "You mean my sister will be a traitor and spy? In vain, I thought you Bai Fan was a benevolent gentleman, but I didn't expect you to be a villain."

"No, I didn't target your sister. I only explained the root cause to you by treating you as a friend. You also have political experience. Why are you so emotional?

Starting from the safety of a country and a nation, will you leave hidden dangers for the tribe? "

Kinderman didn't insist any more, and slowly fell into deep thought, not thinking deeply about Bai Fan's intentions for this move. These are easy to understand. Kinderman admires the person in front of him in his heart. He is not the lord of the country, but he is dedicated to the country and the people. The plan is far-reaching, far superior to ordinary people, and the means are extraordinary. The younger brother of the Goguryeo official, who I would have bent over when I met him, was destroyed on the spot. Such a man is really excellent, why can't I marry him?
