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

This person's name is Qingshi, originally a small Taoist boy in Laojunguan, and later because of his obsession with alchemy, he was sent by Yuan Tiangang to learn alchemy in the Puzi lineage, since Bai Fan served as the descendant of the Taoist sect, and passed down the alchemy pharmaceutical avenue, the Puzi family thought that Bai Fan had obtained the true inheritance, and took the initiative to invest in Bai Fan's door, so Bai Fan took the opportunity to select a group of potential chemists from it.

Leaving a group of people who like medicine to learn real pharmaceutical alchemy, except for the recognized Daomen pharmacists in the world, the other alchemists who refine the Jindan Red Pill have been strictly banned by the Daomen.

"Bluestone master and nephew, the avenue is connected, and medicine also needs to be used, not to mention refining cement, we need to grind limestone, clay, and iron ore powder into powder, but the three cannot be combined into cement after mixing, this gypsum is a blind medicine, without gypsum, cement cannot be refined." Bai Fan patiently explained.

The outer baggage next to him asked puzzledly: "Why do you need eight wind boxes at this kiln entrance?" I'm afraid that the temperature in this furnace can melt anything. ”

"This is not high, only 1,400 degrees, but this is already the limit of our current conditions, I want Datang to create a flame like the sun within 20 years." Bai Fan said longingly.

Li Chun laughed, "Jian Zhi, you are really ridiculous, why do you need twenty years for a sun-like flame?" The flames that come out of the wave of your hand are probably hotter than the sun. ”

……

A group of Daomen chemists looked at Li Chun like a fool, and he was the only one in the audience who laughed, and no one else laughed, and gradually Li Chun felt that something was wrong, what was wrong? It's embarrassing that no one cooperates?

"This, Master Li, Uncle taught us, the sun is a big fireball, very far away from us, when the fireball hits us, there is almost no heat, but the sun itself is about 5,000 degrees, that is a temperature that can be burned before humans get close." Aoshi explained.

Li Chun's laughter stopped abruptly, and he coughed lightly twice, "Joking, it was a joking just now, look, is the cement burned?" ”

Bai Fan opened the eye of the ruler and looked, sure enough, the furnace temperature had reached 1,400 degrees, it was the time when the reaction occurred, because it was only the experimental stage, there were not many raw materials put in, and after a while, it was estimated that the firing had been completed, Bai Fan ordered to stop the kiln, wait for the furnace to cool, and personally stepped forward to take out the finished product.

There are not many things, only a basket of finished products, looking at its fineness Bai Fan frowned slightly, and used the eye of the ruler to see that the cement was burned, but it was extremely rough, only two hundred marks, which could only be used to build houses, not bridges, and at least five hundred marks were required to build bridges.

If it weren't for Bai Fan's eye of the ruler, the cement label would have been tested after 28 days of mixed mortar, and now there is Bai Fan's four-level gift package plug-in, which greatly saves time for the development of cement.

"This thing is indeed cement, but the production is too rough, the quality is not too good, and it can only be used to make houses, which is still far from the needs of bridge production.

Lao Li, it's for you, the things are made, you have the final say on how to use them, you can find these boys if you want things, when they can develop the needs to build the bridge, you have to give them a wine to celebrate. ”

Bai Fan grabbed the wooden basket in his hand and handed it to Li Chun, Li Chun hurriedly hugged it, taking care of the first basket of cement like his own child, and he wanted to take it back to try, is it as Bai Fan said, it is as hard as stone after mixing with water?

Make cement, take out the relevant books and leave them for a few Taoist priests, Bai Fan went back to the academy, the fourth floor of the library is open, then the library of Zhongnan Academy must be built upwards, it used to be a wooden structure, but now with cement, it needs to be knocked down and renovated, all of which are made of reinforced concrete, as for the problem of Datang steel production, Bai Fan is ready to build an iron-making blast furnace.

"Lantian Hou is really a busy man, so the little woman is easy to find."

Before he reached the dean's courtyard, a woman's voice sounded not far away, Bai Fan looked up and looked, isn't this the Silla princess Jindeman? What did she come to do?

"I can't talk about busy people, it's just that there are more trivial things.

There are no official titles in the academy, so the princess still calls me Dean Bai. Bai Fan said with a smile.

"Kindman has seen Dean Bai!"

"Girl, please!"

Took Jindeman to the small courtyard, made it on the stone table, Bai Fan made tea with his own hands, and then asked: "The princess is not going to chase after our emperor, what is the princess coming to me to teach?" ”

This is where Bai Fan is puzzled, he conspired to let her marry the emperor before, this is a very good choice, and the other party seems to agree, but why hasn't it been successful for so long?

Jindeman smiled bitterly: "Providence makes people, I am extremely interested in the singing and dancing of Datang Entertainment City, and I want to perform for His Majesty the Emperor every day, but that day finally waited for him, but he met a very beautiful woman on the way, and there was no one else in his eyes since then."

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

I thought that after you Dean Bai made a move, the emperor would no longer pester Zheng Liwan, and I would have a chance, who knew that I took the initiative to go to the palace to ask for a meeting, His Majesty the Emperor was extremely cold to me, presumably he couldn't look down on me for such a vulgar posture, hey! The little woman's puliu posture has no hope of marrying the emperor. ”

…… Bai Fan was speechless, but his heart was like a mirror, this Silla princess was beautiful, when she first came to Datang, Li Er was really moved by lust, and she had to match up by herself, at that time, Jindeman promised to take a look at it first.

Now it seems that Jindeman is too pretentious, hesitated for a long time, missed a good time, the first time the entertainment city was cut off by Zheng Liwan, the second time he entered the palace and met the eldest grandson Queen was pregnant, and now Li Er wants to please Mrs., so how can he give her a good face?

"This ...... It's true that you're unlucky, 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 of men and women. Bai Fan said embarrassedly.

"Otherwise, I'll marry you, my father was rescued by you, doesn't Datang have a saying that he will repay his kindness with his body? You are younger than the emperor, you have the same ability as him, and the most important thing is that you don't have a harem, so you seem to be more suitable for me than him. Kindman said earnestly.

“…… Hugh is joking, I feel that the four women in the family are lacking in skills, and I will definitely not marry again, and it is okay not to marry the emperor, you can take a look at other unmarried princes, there are many princes of the Tang Dynasty, and they can all be worthy of you. Bai Fan suggested.

"The emperor doesn't look down on me, you won't look down on me, right?" Jindeman stared at Bai Fan with a pair of big eyes and asked.

Shaking his head, Bai Fan retorted: "You and I are friends, you are so beautiful, who will look down on you, it's just that our friendship has nothing to do with anything else, I think it's very pure, I'm not a good match for you, don't be serious." ”

Jindeman smiled, looked at the other party's serious explanation, it was really cute, no longer joking, and said seriously: "Since you and I are friends, then I have something to ask for, I have a younger sister, twelve years old, which is the age of school, I want her to enroll in Zhongnan Academy, you, the dean, are my friend, I don't know if I can open the door to convenience?" ”
