Hearing that the medical officer had gone to his son's aid, the slave kowtowed vigorously.

Li Yuanxing said: "With such a small piece, I am afraid that it will cost more than 100 yuan to refine it!" ”

"Luo, Roman fighting, fighting beasts......" the slave stammered nervously.

At this time, Wu Cao, who had been quietly listening to the previous conversation in the back, rushed out: "The thing extracted from the building materials of the Colosseum in Rome is that someone wants to solve the mystery of the huge building of the Colosseum. The Colosseum used limestone, sandstone, volcanic ash, you know the process? ”

The origin of Wu Cao's tone.

The black slave trembled with fright, and was speechless.

Li Yuanxing didn't ask any more questions, and was about to wait for the black slave's mood to calm down before asking, so he turned his head and asked the strong man: "Tell me!" ”

"Crossbow! Eight crossbows! "Simple and direct statements, but full of confidence.

"What do you need? This king wants to watch you make it! Li Yuanxing has heard of repeating crossbows, but the ancient repeaters restored by later generations cannot show enough lethality, Li Yuanxing regrets that even the cabinet master can't explain it.

"Ten catties of pig iron, ten days can be made!"

"Can thousands of refined steels be used, and can they be built faster?" Li Yuanxing asked again.

The slave lowered his head and pondered for a moment, and said something that made Li Yuanxing cry and laugh: "It depends on whether the steel is good or not!" ”

"Come on, prepare special, first-class, second-class, third-class stainless steel, plus ten catties of pig iron, a separate blacksmith workshop, and two sixth-class blacksmiths. Please come to the scene with the second-class craftsman Lao Ma and prepare quickly! ”

Li Yuanxing finished ordering. Look at the slave.

The slave was not stupid, and knew that when it was time for him to make a request, he cried out, "The little one only wants to be fed!" ”

"Come on, go kill a pig. Give them something hearty and go to the workshop! ”

On the way to the workshop, Li Yuanxing put Wu Cao on his shoulders and asked Wu Cao in a low voice: "You said that ancient Roman cement is better than modern technology?" ”

"It's better to look at yourself, modern industrialized cement, it must be better. But in the eighties, small factories cement is difficult to say. And that requires a lower firing temperature. The only thing that's bad is the recipe. To put it bluntly, it is. Alternatives to volcanic ash, some studies say it is, bauxite powder, and some say others. ”

"Value?" Li Yuanxing asked with a smile!

"You have found the value of ten thousand taels of gold. You say it's not worth it. And you can take this craft back with you. It is placed in modern times. It is also higher than modern cement in terms of environmental protection concept. Ordinary garden buildings are very practical, and building high-rise buildings is free! Wu Cao's explanation made Li Yuanxing very moved.

Secretly instructed that the black slave should be watched. If you raise it well, you can even give enough benefits.

Once the trial production of ancient Roman cement is successful, there is no problem in giving him a knighthood.

In the blacksmith workshop area, the second-class craftsman Lao Ma is already waiting here, and there are four blacksmiths in the workshop who are all apprentices of Lao Ma.

The stainless steel demanded by Li Yuanxing had been prepared and placed on the ground.

In the entire Yaozhou, the stock of high-grade stainless steel is only 1,000 catties, which is used to make armor or weapons for the general.

"Good steel!" Just touching it with his hand, the blacksmith cried out for steel. Li Yuanxing was silent in the face of a smile, but Lao Ma was disdainful, you must know that this is the steel from Yaozhou, which can be said to be the most haode steel in Datang.

Burning, breaking, cutting, after a few movements, Lao Ma's expression changed: "Who is your master?" ”

But the blacksmith did not answer, and the eighteen hammers made a machine buckle out of a small piece of second-class steel, and then eighteen hammers, and another machine buckle, exactly the same machine buckle. Li Yuanxing did not have a measuring tool in his hand, but the visual inspection should have reached an accuracy that could be replaced, and there were only eighteen hammers.

No matter how simple the machine buckle is, eighteen hammers are not something that ordinary people can do.

"Lao Ma, this person has been handed over to you, and he will be treated as a second-class steward, and this king is specially allowed to have a pound of meat every day, and he will be full of dry rice. Let him not be in a hurry, this king wants to see the boutique. ”

"Yes!" Lao Ma, a second-class craftsman, was an expert, and he knew that this strong man's craftsmanship was stronger than when he was younger.

And it is in the prime of life, and there is still a lot of room for improvement.

The simplest meal, ten catties of meat boiled cabbage, which is now cabbage, then white radish, two cooks carrying a large wooden plate put the meal in this workshop, and then a large vat of white rice.

Li Yuanxing personally handed the black slave a pair of chopsticks: "Aluminum-vanadium earth, the material used in the Colosseum in ancient Rome." It's not worse than the king's cement, isn't it? ”

The black slave porphyry knelt down at once, and this action represented acquiescence.

"It's good, it's made. If the effect is good enough, and it is more economical, this king will grant you a county barony. After Li Yuanxing finished speaking, he turned around and walked outside the workshop, and when he walked to the door, he said softly: "Go and tell him, what is the county barony of Datang!" Li Yuanxing smiled and strode away.

The next day, Li Yuanxing, who was in a gentle dream, was shaken awake.

Looking at Wang Yuyan's excited face, Li Yuanxing put the watch under the pillow, half past four in the morning!

Oh my God!

Li Yuanxing tilted his head and was about to fall asleep, but Wang Yuyan didn't follow: "Erlang, isn't today a big day for the rumored steel giant beast to start?" Doesn't Erlang go to the bank of the Jing River? ”

"Behemoth! What is there to see in a stone crusher! Li Yuanxing tilted his head and continued to sleep.

Wang Yuyan was anxious, pounced on Li Yuanxing's body, and scratched Li Yuanxing's whole body!

Woman! Li Yuanxing let out a long sigh and had to sit up. Wang Yuyan was close to him, and the two maids who had already prepared their clothes immediately came over to help Li Yuanxing dress.

Li Yuanxing sighed in his heart, Wang Yuyan didn't dare to speak loudly when he saw him a few days ago, but now he dared to ride on himself and scratch his itch, so soon he was not afraid of himself. Is this the difference between before and after the round house?

Or, they are too gentle, so that they don't have the slightest feeling of fear in their hearts.

Isn't it just a stone crusher!

Li Yuanxing really didn't care, but Wu Cao was completely different from Li Yuanxing, she was ready to go early. Li Yuanxing was dazed, and walked out of the door with three shakes, and almost called someone to help him.

When he went out, an object that Bai Erwa was holding in his hand instantly sobered up Li Yuanxing.

Repeater!

Bai Erwa approached Li Yuanxing: "Your Highness, it was created overnight." A certain tried, seventy steps to shoot through the old Mingguang armor, our new armor, within thirty steps will also die. "Bai Erwa picked the key points and explained quickly and directly, seventy steps! This is a long enough range, and it is a burst of fire.

Li Yuanxing looked at the strong slave!

Although the slave had worked hard all night, he did not look tired at all, but his face was excited. He was close to the crossbow when he tried it, because the steel was good, and the crossbow was stronger than the one he had made.

As a good craftsman, such a masterpiece deserves his excitement.

"Very well, tell me to go down. Give him a home, and he can take a concubine first. However, the rules of the Qin Palace's mansion have to tell him that everything will be said when the king comes back in the evening! Li Yuanxing commanded, and left without looking back.

This is the difference in identity, Li Yuanxing has no need and no possibility to hold a slave's hand to get excited.

Being able to promise a reward in person is already a great importance.

After Li Yuanxing left, a steward of the Qin Palace's mansion came to the slave: "Let's talk about your concubine first, you can pick it yourself." But if you want the other party to agree, Qin Wangfu never forces people to do things, even if they are slaves. His Royal Highness said that a twisted melon is not sweet. The rest of the rules, when you wake up from sleep, will be explained to you in detail! ”

"Thank you for the grace of King Qin!" The strong man grinned.

What is a concubine? When he was not a slave before, he heard from a big family, but now he didn't expect to have it.

Out of Yaozhou City, towards the Jing River. Li Yuanxing looked at the crossbow over and over, all the parts were made of stainless steel, even the part of the crossbow was the same, but there were many strange folds, I think it was to increase the elasticity.

How much does it cost? Li Yuanxing can't figure it out, but whether it can be improved and whether it can be industrialized is a new issue.

When Li Yuanxing arrived at the Jing River, the sky was already bright, and it was already crowded with people. On the high platform, the royal flag has been erected, and it is obvious that the Tang Emperor Li Er has come.

Li Er's arrival was indeed an accident for Li Yuanxing.

Let Wu Cao and Wang Yuyan be together, Li Yuanxing came to the Tang Emperor Li Er.

"Gorou came late, but something was delayed?" Li Er's gaze kept staring at the steel behemoth wrapped in burlap like a small mountain bag.

Ma Yuan's choice of location was very good, and Li Yuanxing just drew a range.

The location he chose was under a rock cliff, and the cart could directly pour the stones into the stone crusher, and then go down, and it was a relatively gentle straight road that could be used for horse-drawn carts to pull away the gravel.

And it is very close to the river, and four huge waterwheels are transported in combination to ensure the power of the stone crusher.

After Li Yuanxing glanced at this arrangement, he shook his head gently. He shook his head not dissatisfied, but in anticipation of the appearance of the steam car, a sign of primitive industrialization above water.

"Brother Huang, if the younger brother says that he is warm in bed and doesn't want to get up, does the royal brother believe it?" Li Yuanxing smiled and gave Li Er a cigarette. Then he helped Li Er to get on the spot. The action of the two, if it is captured by a camera, seems to be the feeling of two gang bosses inspecting the territory.

Li Er spewed a smoke ring and smiled: "For my brother, I would like to believe it, you don't care about these hundreds of thousands of catties of iron at all!" ”

Li Yuanxing smiled and beckoned, Bai Erwa stepped forward quickly, holding a tray in her hand, and knelt down on one knee to hold the tray high. This is the rule, you must not approach the Tang Emperor with a weapon, you can only borrow a tray to hold it. And that's it, even if Bai Erwa is the guard of King Qin, there are two forbidden troops next to him.

"Erwa, you speak!"

"Holy Lord, this thing is a stainless steel repeater, and eight crossbow arrows are fired in an instant. The old armor can be penetrated in 70 steps, and it is easy to load! Three breaths can be reloaded with eight crossbows, and the others have not been tested in time! (To be continued......)
