Four hundred and seventieth nine chapters completed
Next, I went to the steelmaking blast furnace with Heizi.
Now here is not only steelmaking, but also a series of processes such as casting, molding and grinding, production, etc., all concentrated here.
Therefore, some things do not necessarily have to be done artificially. As long as certain key things appear, other ancillary things will naturally appear around them.
Heizi emptied a room and drove all the craftsmen in the room to other places to work. Then he personally worked on the craftsmanship to cast various things that Han Du needed.
Han Du rolled up his official uniform. He was not as solemn and elegant as an ordinary official. Instead, he looked like a scientific researcher wearing official uniform. He held a simple micrometer and kept measuring. After measuring a data, Han Du recorded it casually.
.
This micrometer is indeed crude. It is just two steel rulers of different sizes stacked together and can only slide. But it has many functions. The lower part can measure the outer diameter, the upper part can measure the inner diameter, and when it is put up, it can also measure the depth.
Having these three most important functions is enough for Handu.
With Han Du's constant measurements and constant fine-tuning, together with Heizi, the two of them worked for ten days to complete all the molds.
Looking at the suitable molds placed in front of him, Han Du couldn't help but smile. All the hard work these days was worth it.
Different from Han Du's happiness, Heizi couldn't help but breathed a sigh of relief when he saw that it was finally completed. Originally, he thought it would not be difficult to make a few molds, but under the adults' increasingly demanding requirements, it made him miserable. Over and over again.
The production was scrapped again and again. In the past few days, Heizi couldn't even remember how many molds he had scrapped.
Fortunately, it was finally completed according to the adult's request. Kuroko couldn't help but grab a cloth and wipe the sweat from his forehead vigorously.
Han Du looked at Heizi with red eyes, and couldn't help but said: "No matter what you do, quality is more important than quality. Take casting as an example. If you want to improve your skills, you still have to calm down and do more finesse."
Something. If you do something fine once, it will be better than if you did it ten times a hundred times before."
"Thank you for your teaching, sir." Heizi couldn't help but nod. He himself also clearly felt that his skills had greatly improved in the short period of time following Han Du.
"No need to thank you. This is just the experience gained by many people with their blood and sweat. It doesn't matter if I tell you." Han Du said calmly.
After saying that, Han Du smiled at Heizi, pointed at the mold in front of him and praised: "Don't underestimate these things. Without this, no one in the world would be able to cast these."
Han Du raised the micrometer in his hand.
Heizi himself is proficient in casting, how could he not know the power of the tools in your hands? But although he was extremely envious in his heart, he had no intention of asking for it because he knew that if you wanted to give it to him, then he
Even if you don't say it, the adult will give it to him. If you can't give it to him, then of course there is a reason why you can't give it to him.
To Heizi's surprise, Han Du fiddled with the micrometer a few times, then after thinking for a moment, he put the micrometer in his hand.
When Heizi saw the micrometer falling into his hand, he was in a daze and didn't understand what was going on.
"Sir, what are you..."
Han Du smiled and said: "You have been with me for so long, and I haven't given you anything. This thing is of great use to you, so I gave it to you."
Heizi heard this and was about to return the micrometer. He wanted to refuse, but was stopped by Han Du with a wave of his hand.
"Don't refuse anymore. Come, I will teach you how to use this thing."
Heizi paused for a moment, then swallowed more and said, "Thank you, sir."
Han Du is an official, and Heizi is a craftsman. To be honest, let alone Han Du, he cares about Heizi and treats him well. Even if he beat and scolded him, he did not dare to resist at all. Just like Han Du's previous ones
They all looked down upon the craftsmen and didn't care about their lives. At that time, the craftsmen of the Baochao Lifting Department had to work hard without complaining?
If you dare to disobey, I will tie you up and give you a whip. If you encounter someone with a bad temper, you will be killed and no one will avenge you.
And Han Du can be said to be the best official they craftsmen have ever encountered.
Even if Han Du didn't give him this thing, Heizi would work for Han Du with all his heart. Not for anything else, just because Han Du could let them drink and eat meat, pay them salaries, and keep their whole family fed and clothed.
.
For these reasons, Heizi even sacrificed his life for Han Du, and he did not hesitate.
The most important thing about a micrometer is a unique reading method, which is like a layer of window paper. Even if someone doesn't know how to get a micrometer, it will not have the slightest effect. But once someone who knows how to give you some guidance
, it is revealed in one point, and there is no secret at all.
Han Du carefully taught Heizi how to use a micrometer, and after making sure that he had learned it, he said: "Okay, now we should make things."
"Sir, please rest. Leave the rest to the younger ones." Heizi was very excited now and would let Han Du do it himself.
Han Du didn't try to be brave. Heizi was indeed much more capable of casting these things than he was. Just carrying a heavy metal solution and ensuring that his arms trembled a little, Han Du couldn't do it.
After working hard all day, Heizi finally produced two sets of parts according to Han Du's requirements.
Han Du picked up the parts and assembled them one by one. Soon, two identical objects with beautiful bright silver were placed in front of Han Du.
Looking at the familiar object in front of him, Han Du couldn't help but have a fierce light in his eyes. Who would have thought that something this foot long could be a big killer?
Han Du couldn't help but take it in his hand and stroke it gently.
Heizi stood aside without saying a word. Although he was also curious about the use of these two things, he didn't ask any more questions.
Han Du looked at Heizi and saw that he had a puzzled look on his face. He had no intention of explaining to him. Instead, he continued to ask: "Where are the other things?"
"They're all here," Heizi picked up a wooden box and handed it to Han Du, "These are made according to your request, there are ten in total."
Then he picked up a wooden box and put it on the table, opened it toward Han Du: "There are also these, two hundred in total."
Han Du took a look and confirmed it was correct.
He nodded and ordered to Heizi: "Go and tell Mr. Huang to find a carriage to take me back. Also, wrap up all these things and put them on the carriage."
