Martial: I Started The Technological Revolution In Ancient Times

To Xiao Yun, it was probably by His Majesty's side.    

Because if he wanted to take your life, he was definitely the person who could kill you the easiest. On the contrary, even if you collapsed beside him, it would still be fine.    

When he returned home, Xiao Yun still felt a headache.    

However, he didn't have the time to rest.    

He immediately asked someone to find Han Sui.    

He also asked him to bring a few of the best craftsmen.    

In the beginning, Xiao Yun wanted to use casting iron for the heating system, but the amount of manpower and resources needed to smelt iron was too much.    

The cost was low, but the cost was high.    

This was not what Xiao Yun liked.    

Hence, he chose copper in the end!    

As for how to use copper to forge a row of heating packages, or rather, commonly known as heaters,    

Xiao Yun thought of the wax loss method.    

Although this method seemed ancient, it could eliminate sand eyes to a certain extent, and it was a convenient way to use it.    

When Xiao Yun saw the craftsmen, he didn't teach them the technique first. Instead, he chatted with them and used Han Sui to confirm whether they were trustworthy.    

In just a few words, Han Sui also understood what Xiao Yun meant.    

He emphasized their personalities and their families.    

It was very difficult to find a loyal person.    

There were a few simpler methods, such as having a beautiful family.    

There were also those that had a good reputation among the neighbors.    

Morals were one aspect, but the most important thing was to tie them together.    

When a person had a very good life, the price of betrayal would be very high!    

Han Sui really knew Xiao Yun very well.    

After getting his order, he had already considered this point when selecting people.    

Therefore, these few people were the most reliable, or rather, they were the easiest to control.    

Xiao Yun looked at Han Sui and nodded at him with satisfaction.    

Then he asked Qing'er to take out some things from the room.    

The most important thing was wax.    

"A sword. If all the tools are prepared, what is the fastest way to make it?"    

Xiao Yun asked a question that made everyone speechless.    

After a while, someone tried to say, "It is still faster to forge it. After all, it takes a lot of time to form it. If we use the current forging method... The forging speed was really too slow. Now, it was a high-grade blade. It'll take seven or eight days to complete. Of course, our saber is also the best. "    

Another person nodded and said, "Indeed, the forging method is very convenient. Previously, due to the temperature of the furnace, it was very difficult to forge iron artifacts. Only our workshop could do it, so the forging method is the fastest and the best."    

Xiao Yun laughed and said," The judgment is quite accurate. Today, I will teach you a method that is faster than ordinary forging. Of course, in order to make it easier, we will not use iron tools this time, but use copper. "    

Under everyone's puzzled and excited gazes.    

Xiao Yun carved a complete piece of wax into a strange-looking shape. It was hollow in shape, and some parts were extremely slender. It was almost impossible to grind and carve it.    

At first glance, the shape looked like a ball of hair that had been tied up tightly.    

However, if one looked closely, they could see all kinds of subtle shapes, as if dozens of totems had been kneaded together.    

One of the craftsmen couldn't help but ask: "Young master, what are you... doing?"    

Xiao Yun smiled and said, "Look closely."    

He took out an iron bucket and put the wax inside. Then he added some very fine sand. The composition of the sand was special.    

With a light tap, the sand would seep into any gap. As long as some water was added, the sand would immediately be fixed in its current shape. It was very tough and strong.    

There was a hole under the iron bucket that was connected to wax.    

There was also a hole on it, and it was also connected to the wax pieces below.    

He took the things and went to the forging room of Xiao family. He boiled a pot of copper water and poured it into the hole on the iron bucket.    

At the same time, a magical thing happened.    

There was melting wax dripping down from below.    

Until...    

The wax completely disappeared and what flowed out was copper.    

Xiao Yun immediately stopped, and blocked the hole below. He filled it up, and allowed the copper water to flow out.    

Then, a basin of water was poured on top of it, causing the temperature of the entire metal bucket to quickly drop.    

After a few buckets, the white fog stopped rising.    

Xiao Yun split open the metal bucket and used his hammer to knock off the solidified soil.    

The last thing that was left behind...    

It was a piece of copper!    

The shape of the copper, apart from the rough edges and the details that were not smooth enough, everything else... be it the shape, appearance, size, or even the details were exactly the same as the wax figure from before!    

"This!"    

As the saying went, the layman watches the show, while the expert watches the trick.    

After Xiao Yun's actions, those shrewd craftsmen immediately understood how Xiao Yun did all of this.    

Everyone widened their eyes and looked at Xiao Yun with disbelief.    

It was because this method was too ingenious!    

Xiao Yun did not explain too much. He just used the small file knife to fix the copper piece, and then used a smaller file knife to grind the details.    

Very soon, a shining bronze art piece was born in Xiao Yun's hands.    

The craftsmen did not even dare to blink during the whole process.    

They were afraid of missing out on any details.    

They knew that Xiao Yun would not tell them the details if he taught them.    

No matter how much they could see, it was their own fortune.    

Only those who had mastered this skill were qualified to walk to the end and become the core figures of the Xiao family's workshop.    

After he finished cooking, Xiao Yun sat there and slowly ate the tea and fruits Qing'er brought over.    

He didn't say a word throughout the whole process.    

After about ten minutes, a craftsman walked over and carefully observed the wax flowing out, especially when they had already formed wax blocks on the ground.    

After the time it takes for an incense stick to burn, another craftsman came up and carefully studied the sand that had been burned into solid pieces by the high temperature.    

After a while, a person walked directly to the place where Xiao Yun had placed the raw materials and took out all the things he had used. In fact, there were still some left. He took them out and looked at them one by one, then closed his eyes and silently thought about it.    

He walked directly in front of Xiao Yun, bowed deeply, and carefully asked, "Young Master, this lowly one... can I try?"    

"A short knife is enough. Don't waste time."    

"Understood."    

The man immediately used Xiao Yun's technique and quickly made a small knife. It was only the size of a palm and had a lot of spikes on its fur. It was different from the wax shape that he had carved before.    

He was stunned for a while, then knocked his head hard and said in a low voice, "I forgot to knock on the cylinder wall. I did not make the sand fill up completely."    

Only then did Xiao Yun nod his head.    

Then he stood up and said, "The seven of you don't need to be divided. Do this job well together. And now there's a job to do right away, so there's no need to hide it from you. We'll make a set of warm things for His Majesty and use them to make big money in the workshop in the future. So, you must not make a mistake. "    

After saying that, Xiao Yun threw a design picture over.    

It was the size of a study and the length of each official road.    

He didn't need to carefully look at these things. With just a glance, he could tell the exact size.
