Du Jin picked it up and looked at it, and said in astonishment: "What a big crystal stone. Where did you get it?"
Xu Zizhen said: "You don't care where it comes from. I'm just asking you if you can make this thing into a piece."
The thing he took out was the large crystal that Bu Fen and others collected from the Western Regions. Xu Zizhen hid it for a long time, waiting to ask Du Jin to see if he could operate it.
Du Jin frowned and looked at it for a long time, then nodded and said: "Okay, okay, how thin do you want the slice to be?"
Xu Zizhen himself didn't have an accurate idea. After thinking for a moment, he compared the thickness with his thumb and index finger: "It's almost this thin, can it be done?"
"What color should I carve?"
"No flowers are needed, just thin it and polish it. The brighter the better."
Du Jin raised his head in confusion: "Just polishing without carving? What's the use? Such large crystal stones are rare, isn't it a waste?"
Xu Zizhen smiled mysteriously: "You will know when you grind it out."
Du Jin didn't ask any more questions and put the crystal away: "Okay, this is a piece of work. It won't be done in ten days."
Xu Zizhen scratched his head: "I'm afraid you have to work harder, because it's not just grinding." He took out the charcoal pen again, took a piece of paper and drew a few strokes, "The edges should be thin and the middle should be raised.
Is it possible?"
Du Jin picked up the paper and looked at it: "Okay, it will take three or four more days."
Xu Zizhen was happy: "Okay, then I'll wait."
Not to mention that having an old man in the family is like having a treasure. Xu Zizhen now feels that Du Jin is not just a treasure, but an unfathomable treasure. No matter what he has in his hands, there is always a way to solve it. It is really comfortable.
After he finished speaking, he was about to leave, but Du Jin grabbed him and said angrily: "You kid, are you leaving now? Don't you want to see your big killer?"
Xu Zizhen suddenly stopped at his feet and his eyes lit up: "Did you really do it?"
Du Jin said: "It's not that easy. There are still some small steps to complete, but the general outline is out. Come and take a look first."
Xu Zizhen followed Du Jin to the backyard. It was an open yard. He built a shed with big bamboos and covered it with an oilcloth. The whole yard was covered tightly, not even the light could penetrate. Du Jin asked someone to
He lit a lamp and personally led Xu Zizhen inside. There was a large object placed in the center of the yard, also covered with a large piece of oilcloth.
Du Jin waved his hand, and two guys came over and lifted up the oilcloth, revealing an iron lump about half a man tall.
Xu Zizhen's eyes suddenly widened and he looked at the thing in front of him without blinking. He stretched out his trembling hand and gently touched the object, and said excitedly: "You really made this thing? Really made it?"
Already?"
Du Jin pulled him away, stepped in front of the thing, and asked: "You didn't tell me what this thing was when we arrived, can you tell me now? Brothers have been working blindly for more than two months.
."
Xu Zizhen looked at the thing a few steps away, his cheeks flushed with excitement. He swallowed and whispered: "The advent of this thing can boost the national power of the Song Dynasty for hundreds of years. Do you think so?"
What a good thing? If you really want to know the name, this is called - steam engine."
Du Jin couldn't help but be startled. National power has been promoted for hundreds of years. This is no joke. However, from the time Xu Zizhen gave him the blueprints to now, he has only concentrated on manufacturing, but never knows what the use is. Although Xu Zizhen said it very well
It was serious and solemn, but he was still confused and couldn't help but ask: "Is it so rare? But how do you use it?"
Xu Zizhen took a deep breath to suppress the excitement in his heart, and said with a smile: "It's useless to talk now, there is no chance to test it, you will know it later." At this point, he paused, his expression became solemn, "This thing is
Only we brothers know this, and we must not spread it out."
Du Jin became more and more curious when he heard what he said so seriously.
Xu Zizhen walked around the iron guy a few more times and looked at it carefully. This was said to be a steam engine, but in fact it was a simple version. He had long had the idea of ​​developing technology in his mind, but it was a pity that he didn't read much and didn't study physics when he was in school.
I didn't learn it well, I can only remember the general principles.
Not long after he first came to Yingtian Mansion, he asked Bao'er and Qiaoyi to find such a good place and spend a lot of money to buy the garden in order to use it for Du Jin and others to research and develop his rare things.
, this steam engine is the first big object to bear the brunt.
The steam engine was not yet completed. He took a closer look and found that the overall fuselage was fine. Xixia's forging technology would definitely prevent the iron shell from bursting under high pressure. It was a pity that valves could not be made these days.
Even the steel balls in the rollers had to be polished by hand, so it took too long to build a working steam engine.
Xu Zizhen walked around several times, looking and touching. The more he looked, the more proud he became. He suddenly raised his head and shouted: "Luo Ji!"
A black figure flashed from the roof, leaped to Xu Zizhen, and knelt down on one knee.
"master."
Du Jin and others were startled by this unexpected visitor. They were all very skilled, but no one noticed Luo Ji's presence.
Xu Zizhen pointed at the steam engine and said: "Send a few brothers to guard this garden and don't let anyone get close. This thing must be kept secret, do you understand?"
"Yes!" Luo Ji responded simply and directly, then stood up and disappeared on the roof.
Du Jin was stunned, and it took him a while to come back to his senses: "Where did you get such a master from?"
Xu Zizhen said unhappily: "Look at what you said, what is a trap? This was given to me...well, it's actually a dowry."
Du Jin and his guys couldn't help laughing. Wen Baer said with a smile: "My wife was quite prosperous when she got married, but she only got some gold and silver as a dowry. Master, which family did you marry this time?"
The girl is a gift to a master? Could it be that she is the daughter of some general?"
Xu Zizhen said proudly: "You're right, it's really..." He stopped just as he said this and slapped his hand, "Oops, I forgot about this."
He had made a promise with Master Yong that Tianfu would propose marriage to the Gao family, but when he turned around he completely forgot about it, and when he saw Mr. Gao Pu, he didn't even remember it. Master Yong had said that he would marry him soon.
I will come to Yingtian Mansion again, and when the old man gets angry, he will suffer.
Thinking of this, his mind started to spin again. Marrying Gao Pujun is not that easy. This girl is very demanding. She is called Shi'er Mom. If you don't make the wedding different, I'm afraid you will have more shoes for yourself in the future.
wear.
He touched his chin and pondered for a moment, then slapped his thigh and shouted: "Yes!"
Everyone was startled by him: "What's going on?"
Xu Zizhen's face was suddenly filled with a flattering smile, he looked at Du Jin and said: "Uncle, can you make something for me again?"
