Chapter 293

In Laizhou, Qian Dafu looks at the busy slaves and drinks.

He cried all morning, hoarse, and had been directing slaves to build all kinds of buildings in the mining area.

In order to speed up the delivery of tungsten ore powder, some slaves were already excavating tungsten ore, and some slaves were screening, enriching tungsten ore powder mixed with soil.

"Second uncle, your highness is here." At this time, a young man came to Qian Dafu and said.

"Here comes your highness?" Qian Dafu almost jumped up from his chair. He said to the young man, "Qian GUI, your highness will come later. Don't talk about it. Let me tell you about going to Bowen college."

"Second uncle, I listen to you." Qian GUI nodded, with a trace of expectation in his eyes.

Some cavalry in armor appeared in the mining area at this time. These cavalry looked very brave, not to mention they were the guards of Xiao Ming.

When Qian Dafu saw him, he immediately stepped forward and saw Xiao Ming surrounded by cavalry.

"Your Highness, you've come all the way here in person." Qian Dafu welcomed him with a smile all the way.

Seeing Qian Dafu, Xiao Ming smiles and says, "come and have a look. By the way, I'll send you the slaves Liang Dahai brought from the grassland. Five thousand people are enough."

Qian Dafu looked at the slaves guarded by the cavalry and said with a smile, "Oh, Liang Dahai has grown up a bit of brain at last. Now all he bought are strong slaves. Enough, enough. These 5000 people are equal to the former 10000."

"If you don't grow a little brain, I'll let him go home and farm." Xiao Ming dismounted as he spoke.

He went over Qian Dafu and looked at the slave who was digging at the bottom of the mine.

Since ancient times, mining has been a very hard work. Without modern machinery, we can only rely on slaves, chisels and digs. A metal mining area often stretches for several miles.

Now these slaves only dug about five meters of the surface layer, and the tungsten ore powder content in this layer area is very thin.

"Your Highness, this mine is wolframite."

Qian Dafu gives Xiao Ming a white and black stone. The ore looks like coal. If the ore doesn't show some transparent crystals, he will suspect that it's a coal mine.

Xiao Ming nodded with satisfaction. Scheelite is widely distributed, but it is generally poor, while wolframite is less distributed, but it is generally rich. Moreover, wolframite is associated with tungsten and manganese. To find wolframite is to find manganese, while scheelite is a calcareous ore.

Xiao Ming's heart was filled with joy when he padded tungsten ore. The reason why he asked Qian Dafu to look for wolframite was that he needed both tungsten and manganese.

After watching the slaves dig for ore, Xiao Ming goes to the place where tungsten ore powder is screened. He is very satisfied with Qian Dafu's work efficiency, which has achieved results in a few days.

However, it was also at the expense of the slaves, because there was no complete house in the whole mining area, only a few tents.

"You sleep in a tent these days?" Xiao Ming was touched in his heart. Qian Dafu can really be elected as a model worker in modern times.

"I can't help it. The cement and bricks in Qingzhou will come some days later. Now I have to pay attention to them. Fortunately, it's not cold now. If it's nothing, the slaves will come over with quilts on their backs, and it's not cold for a large group of people to live together."

"Ah, I've worked hard for you. I'll be tired for a while. After a while, I'll ask the government to reward you." Xiao Ming said with a smile.

Qian Dafu laughs honestly. At this time, his nephew comes out and says to Xiao Ming, "Your Highness, his name is Qian GUI. He is the nephew of the old slave."

"How much is money? Is that your nephew who was made a slave of the government? "

"That's right. The empress was very kind. Not long ago, she pleaded with the emperor and pardoned him. Then he came back from Chang'an and went to the old slave. His highness also knew that he was the only relative left in the old slave's life. The old slave was like this again. The incense of the money family could only depend on him, so he wanted to treat him as his own son."

Qian GUI also bowed to Xiao Ming and said, "Qian GUI has seen your highness."

In fact, Qian Dafu is equivalent to the yellow gate in the palace. He can't bear children all his life. Naturally, Xiao Ming knows the importance of the only nephew left to him.

In the past, Qian Dafu seldom asked him, but now he must be eager to say so.

He takes a look at Qian GUI, but it's similar to Qian Dafu. Princess Zhen asks Xiao Wenxuan for help, which seems to be a reward for Qian Dafu over the years.

So he said, "it looks like you're loyal."

"Your Highness, it can't be wrong that our family style is like this." Qian Dafu laughed, "Your Highness, do you think Qian GUI can take the place of Lao Nu to go to the school of Bowen to learn something? In this way, Lao Nu can concentrate on the mining area, and he can take the place of Lao Nu to go out to look for the mine, otherwise Lao Nu really can't stand it."

"Well, you have a point." Xiao Ming once again looked at Qian GUI, he said: "in this case, let him go to Bowen College for a period of time.""Thank you, your highness." Qian Dafu was relieved when he heard the speech.

Even if it's not for Qian Dafu's sake, he has to cultivate a few talents for mineral exploration. After all, the talents in Qingzhou can be counted by fingers, and a group of young talents are urgently needed to support the future industrial development.

After inspecting the mining area, Xiao Ming returned to Qingzhou with three tons of tungsten ore powder that had been mined by the slaves.

With tungsten ore powder, he went directly to the equipment department.

"Your Highness, how to make this spring?" Song Changping has a sniffle. Recently he has a cold.

The research of suifa gun was put on the agenda. Naturally, he had to gather the most powerful research team in Qingzhou, and all the talents from the equipment department were gathered again.

However, Xiao Ming did not ask them to study flint guns together, but assigned them their own tasks. Zhang Liu and others were responsible for the production of tungsten steel cutting tools and gun barrels.

According to Xiao Ming's plan, Chen Qi will be responsible for the artillery in the future, while song Changping will be responsible for the research and production of guns.

Although the barrel of the gun has not yet been located, the production of small steel balls and the research of the gun can be started, and these steps can be synchronized. After all, Xiao Ming does not start from scratch, but has the means of production for all kinds of guns.

"This is how to extract tungsten from tungsten ore powder." Zhang Liu added.

These two problems are technical difficulties. The spring needs to solve the elasticity of steel. As for the purification of tungsten, at the present level, Xiao Ming can not guarantee the purification rate, but even 20% is enough.

"One by one, Zhang Liu, you go to deal with the mold first. Song Changping, you stay. I'll tell you about the structure of the gun."
