Xu Mochen and his entourage came to the National Research Institute.

There was a group of people waiting in the hall, Xu Mochen looked over, these people were all powerful, and their palms were full of thick calluses, obviously people who had been engaged in manual labor for a long time.

"Childe," Li Yihang introduced, "These are the craftsmen of Jinzhou forging and smelting, and they dare not say that they are the first people in the country, but they are also top masters."

Among the group of people, the leader was a middle-aged man, who had long known Xu Mochen's identity, and stepped forward to salute at this time: "The grass people in Jinzhou Duan Bailian, the people in the countryside don't understand the rules, please forgive Your Majesty."

"That's it," Xu Mochen didn't care, he waved his hand, "Jinzhou is not far from the capital, I have read the geographical records, and there are rich minerals there, so smelting technology has been derived."

"Your Majesty Shengming," Duan Bailian first buckled a top hat over, "In Jinzhou, in addition to iron and copper mines, there are also coal mines, so since ancient times, it has been a good place to smelt weapons."

In ancient times, logistics was underdeveloped, transportation was very troublesome, and local materials became the key to the growth of many technologies.

Jinju was able to develop forging and smelting technology, which can be said to be unique.

Duan Bailian waved his hand, and someone immediately stepped forward with a rectangular box.

"Your Majesty," he laughed, "This is the sword refined by our Duan clan, and we present it to Your Majesty, wishing Your Majesty prosperity and peace in the country."

Xu Mochen's consciousness swept away, and he already knew that the box was a sword, and he was also interested: "Take it and take a look."

opened the box and handed it to Xu Mochen, only to feel a cold air coming up.

Xu Mochen was slightly surprised, this is a sword made by the human race, but its level is actually a fight with the sword in the Xianxia world.

It's just that the sword doesn't have the runes of immortal cultivators, so it can't absorb aura, and the effect is a little worse.

But this quality, I really don't have to say.

"This is steel," Xu Mochen smiled, "It's not ordinary steel, I didn't expect you to be able to forge it."

He picked up the sword and touched it lightly, and the box split in half.

The modern craftsmanship that Xu Mochen knows, and the swords he makes, are almost to this extent.

"What is the current level of smelting in Daqian?" He was very satisfied, put the sword aside, no matter how good the weapon was, it could not be popularized among the people, and it was not the focus of Xu Mochen's attention.

"Your Majesty," Duan Bailian stepped forward to report, "Brother Li and the grass people and others have said that what Your Majesty wants is steel."

Xu Mochen nodded, he was right, but not all.

For smelting technology, although Xu Mochen is a traverser, he is not a jack of all trades.

He knows a little about the principle of steelmaking, simply put, it is to take iron as the foundation, further remove the impurities contained in the iron, inject more carbon elements, and make it change its structure, and then become steel.

He focuses on the level of smelting because he needs other metal smelting than steel.

The modern industrial system is a huge and complete framework, which cannot be realized by engaging in a single metal.

"Let's talk about steel first." Everything is difficult at the beginning, and he thinks it is better to start with the easy ones.

"Actually, this steel was discovered a long time ago," Duan Bailian was familiar with the history of the development of Daqian smelting technology, "In ancient times, in addition to smelting bronze and iron, occasional technicians could also train steel.

Of course, at that time, there were more accidental factors, because the temperature of the fire, forging and tempering, etc., were all explored little by little."

Xu Mochen nodded, if there is an immortal cultivator to help and use different fire to quench, the effect will definitely be good.

But the immortal cultivators didn't care about the level of technological development of the human race, and it was estimated that what was introduced at that time was only the simplest method.

All of this is still accumulated and precipitated by the human race itself little by little over hundreds of thousands of years.

This is the crystallization of historical wisdom.

Over there, Duan Bailian continued to introduce.

Accumulated over generations, steelmaking can now be said to be a relatively common technology.

One is 100 steel, the so-called 100 steel, in fact, in the process of forging and smelting, the iron is constantly heated and forged, and it has been repeated.

Even hundreds of times.

By forging, the impurities in the iron are separated to obtain the best effect.

There is also a type called steel filling, which is to smelt pig iron and wrought iron together and fuse them together to further promote the formation of steel.

Either way, manual work is essential.

"This sword brought by the grass people was made by the Hundred Steels Technique," Duan Bailian said, but his face gradually became depressed; "But these skills that the grass people said can only make relatively large things.

What kind of injection needle Brother Li showed the grass people, if it is so small, the grass people really can't do anything."

In other words, with the current technology, there is no way to directly make molten steel for cooling and pouring.

"Do you have any drawings of your steelmaking equipment?" Xu Mochen asked.

"Yes," Duan Bailian took out a piece of paper and handed it over, "Before the grass people came, they thought that His Majesty might need it, so they let people depict the process of smelting."

Xu Mochen took it and looked at it, it was written in detail, and the tools that could be used in this era were basically used.

But that's not enough.

"I have a new smelting technology," Xu Mochen pondered, and slowly spoke, "I can remove as much impurities as possible in the process of firing molten iron, and turn it into steel in one step."

As soon as these words came out, Duan Bailian retreated in fright.

You are the emperor, how can you still understand steelmaking?

It's unreasonable, don't emperors either go to the court or go to the harem?

Xu Mochen didn't pay attention to Duan Bailian's surprise: "If you want to know the details, I will show you the information when the time comes, so you can refer to it and learn it."

But you don't have to blame yourself, now I've found an alternative to producing injection needles for the time being, and if it's made of steel, I'll take a break.

Seeing you today, there are some issues that need to be studied together."

Duan Bailian was stunned when he heard it, he was worthy of being an emperor, and he couldn't understand some of the words he said.

But it can be roughly understood.

Xu Mochen signaled later, and asked Li Yihang to find Fang Minghang and Fang Mingying's brothers and sisters.

He entered another room, swept his senses, confirmed that there was no problem, and then took out the ring armature generator that the Dao Fruit Barter had replaced from the Qizang Divine Mansion.

This generator is an early version, the structure is not complicated, Xu Mochen has learned the principle of electromagnetism, and knows the origin of power generation.

When everything was ready, he went back and brought the people over.

"It's called a generator," Xu Mochen patted the machine, "I mean that it can be used to generate electricity."

Well, I admit that electricity may be too profound for you.

Fang Mingying frowned: "Your Majesty, the electricity you are talking about, but the electricity of wind, rain, thunder and lightning?"

On thunder and rainy days, they have all seen lightning in the sky, and it is very powerful.

So, Your Majesty is preparing to create a new type of weapon.

Realizing this, everyone's faces changed.

Some of them have seen it, some have heard of it, and this thunder can easily kill people when it falls.

Now that the world is unified, what else does Your Majesty need a new type of weapon for?

Are you going to stab people again?
