Next, he and Heizi came to the steelmaking blast furnace.
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 it.
Heizi emptied a room and sent all the craftsmen in the room to work elsewhere. Then he personally cast various things that Han Du needed.
Han Du rolled up his official uniform, not at all solemn and elegant as an ordinary official. Instead, he looked like a scientific researcher wearing official uniform. Holding a simple micrometer, he kept measuring. Once a piece of data was measured, it was recorded by Handu.
This micrometer is indeed crude. It is just two steel rulers of different sizes stacked together and can only slide. But it has a lot of functions. The lower part measures the outer diameter, the upper part measures 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.
Under Handu's constant measurements and constant fine-tuning. Together with Heizi, the two of them worked for ten days before completing 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.
Unlike Han Du's happiness, Heizi couldn't help but feel relieved 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' demands, he became miserable. Made over and over again, 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, it's all about finesse but not much. 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 nodded. 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's 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 the adults for it. Because he knew that if the adults wanted to give it to him, they would give it to him even if he didn't say anything. 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.
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 will give 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, then choked and said, "Thank you, sir."
Han Du is an official, while Heizi is a craftsman. To be honest, don't say that Han Du cares about Heizi and treats him well. Even if he was beaten and scolded, he would not dare to resist at all. Just like the one before Han Du, he simply scorned the craftsmen and didn't care about the life and death of the craftsmen. At that time, didn't the craftsmen of the Baochao Lifting Department have to work hard and without complaint?
If you dare to disobey, even if you are tied up and whipped, it is considered a light punishment. If you encounter someone with a bad temper, you will be beaten to death, and no one will redress your grievances.
And Han Du can be said to be the best official these craftsmen have ever encountered.
Even if Han Du didn't give him this thing, Heizi would still work for Han Du with all his heart. Not for anything else, just because Han Du can let them drink and eat meat, pay them salaries, and keep their whole family fed and clothed.
For this, Heizi even sacrificed his life for Han Du, and he did not hesitate.
The important thing about a micrometer is a unique set of reading methods, which is like a layer of window paper. Even if someone who doesn't know how to get a micrometer, it won't have the slightest effect. But once someone knows how to give you some pointers, it will be clear to you, and there will be no secrets.
Han Du carefully taught Heizi how to use a micrometer and waited until he was sure that he had learned it. Then he said: "Okay, now we should make things."
"Sir, please rest. Leave the rest to the younger one." Heizi was so excited now that he would let Han Du do it himself.
Han Du didn't try to be brave. Heizi was indeed much more capable than himself in forging these things. Han Du couldn't do it just by holding a heavy metal solution and ensuring that his arms could tremble a little.
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 confused look on his face, and 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 another wooden box and placed it on the table, opening it towards 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."
Kuroko nodded in agreement.
