Emperor: When will the Seventh Prince rebel? I will open the city gates to welcome him.

Although he had never been to school, he knew that there was no reward without merit.

"Haha, no problem, no problem! Even if it's not an iron mine, I will still appoint you as an official. I have just established my own power and official positions in the land of Northern Yan, and many positions are vacant. If I can find someone I like, I will appoint him as an official! It just so happens that I like you. By the way, what's your name!"

Liu Wazi said in panic:

"Commoner Liu Xiahui!"

Hongxuan was stunned and remembered a name he had heard before, also called Liu Xiahui.

There is another reason why Hongxuan is so generous now, that is, Hongxuan is absolutely sure that the reddish-brown hard stone that Liu Xiahui mentioned is iron ore!

In fact, when it comes to iron ore, black magnetic iron ore is not the most common iron ore. The truly common iron ore is reddish brown.

Because the reddish brown color is the oxidation of iron, the bright black iron ore also has magnets attached to it.

The Qilin Guards had prepared all the supplies, and Hongxuan also sent a part of the Qilin Guards to the northern border.

The reason why Hongxuan sent the Qilin Guard to the northern border was that he was absolutely sure that the ore was iron ore.

Notifying the Fourth Frontier Army and the 5,000-strong logistics support team earlier would have been an early plan.

The logistics support team has a wide range of uses.

For example, a force specially established to manufacture iron tools can be called an engineering corps.

And after confirming the iron ore, Hongxuan would naturally set up a special engineering corps to mine the iron ore. After mining the iron ore, an iron smelting plant of corresponding scale would be built nearby.

The term "factory" is a very advanced term, representing advanced power.

A noun that does not belong to this era, but now belongs exclusively to Wang Hongxuan of the North.

Before leaving, I, the Northern King Hongxuan, spent a whole night with my two beloved concubines.

The whole team set out the next day.

Hongxuan brought all seventy-eight blacksmiths with him, and specially arranged Liu Xiahui to be by his side.

This way, it will be convenient to give directions.

You can also learn about the iron-making process of Dafeng blacksmiths through Liu Xiahui.

A journey of more than 200 kilometers is not long.

If it is a fast horse, it can travel eight hundred miles a day.

Of course, if the troops marched two hundred miles, it would take three or four days.

Because this time they not only brought a lot of tools, but also a lot of equipment. The entire army did not rush to Mangdang Mountain on horseback.

Qilin Guards and Iron Mines all felt it.

Zhenbei Wang Hongxuan determined that the reddish-brown ore was iron ore.

Otherwise, how could he bring so many unimportant things with him, even the iron smelting equipment.

Hongxuan has been on the road to move forward, not that he doesn't want to stop and rest.

But the area of ​​Northern Yan that he took over was actually a mess.

It will take the King of Zhenbei alone to turn the tide.

After three days of traveling.

Under the guidance of Liu Xiahui, the whole team finally arrived at Mangdang Mountain.

"Your Highness, that is Mangdang Mountain. It was on that mountain that I discovered a reddish-brown hard ore."

Hongxuan suppressed the excitement in his heart. The more critical the moment was, the more he could not show his joy on his face, so as not to fail.

The Mangdang Mountain here is not a barren mountain, but a mountain with trees.

Hongxuan put down his horse and walked instead.

The mountain road was not steep, but horses could not go up, so all the horses were left at the bottom.

Under the guidance of Liu Xiahui, they came to the hillside of Mangdang Mountain.

"Look! That's exactly what I'm talking about, Your Majesty."

Hongxuan looked in the direction Liuxiahui pointed.

The whole mountain is reddish-brown in color.

Zhenbei Wang Hongxuan ran forward.

The Qilin Guards also followed, ready to protect Hongxuan at any time.

When Hongxuan came closer, he casually picked up the reddish-brown ore on the ground.

There was a crisp sound when the ore in the left and right hands hit each other.

The corners of Hongxuan's mouth curled up unconsciously:

"That's right, hahahahaha, it is indeed iron ore, it is indeed iron ore!"

Hongxuan became very excited.

"Where is Deng Yongmen? Deng Yongmen, come quickly and listen to my orders!"

At the summons of Qilinwei, Deng Yongmen came before the King of Zhenbei.

"Deng Yongmen, pass on my order! Move all the troops of the Fourth Legion here and bring enough food!"

"I want to forge iron and manufacture weapons right here, and quickly!"

Deng Yongmen looked at the two reddish-brown stones in the hands of King Zhenbei:

"Yes, I obey your command!"

He didn't dare to disobey the orders of King Zhenbei, nor did he dare to raise any questions. He just had to do what he was supposed to do.

After receiving the order, Deng Youmen mobilized the Fourth Army to come outside Mangdang Mountain.

Of course, the Fourth Army had two other commanders, namely Yu Deshen and Li Donglin.

Hongxuan can't wait to smelt the reddish-brown ore in his hands.

In fact, refining iron ore is not complicated and generally requires six steps.

Ore dressing, crushing and grinding, sintering or pelletizing, reduction (using coke, coal powder as reducing agent), smelting and refining.

Hongxuan only knew how to refine it, because he didn't have the level to do so now, so as long as it could be smelted into molten iron, he would be considered successful.

As long as you make a high-temperature furnace and complete the first five steps, molten iron will be formed in the end. If molten iron can be formed, it means that it is iron ore. If only slag is left and no molten iron in the end, it means that these are just ordinary stones, not iron ore.

But now Hongxuan is 100% sure that what he has in his hand is iron ore.

Not only that, Hongxuan also believed that the iron content of the iron ore in his hands was very high, and it was a very high-quality iron ore far higher than those black and shiny iron ores.

"Qilin Guards, listen to my orders!"

"I obey your orders!"

"You Qilin Guards, issue a military order to build this place into a military camp to accommodate all the soldiers."

Qilin Guard said respectfully:

"Your Majesty! Are you sure you want to build a fixed military camp here?"

Because if a fixed military camp is established here, then these people will have to stay here.

Only stationed troops require fixed military camps.

"Just pass on my order and do it. You don't have to worry about the ore here being iron ore! I'm just speeding up the progress of time. I don't want to do anything and drag my feet."

"The sooner we can manufacture those Iron Army crossbows, the sooner we can destroy those Northern Merchants' cavalry."

“Not only that, as long as my army is equipped with composite crossbows and enough crossbow arrows! By then, the Beishang will be mine!”

The Qilin Guards were shocked when they heard this.

Since King Zhenbei said so, it means that the ore here is iron ore. They couldn't believe that a mountain was full of iron ore. How much iron ore should there be? It was simply unimaginable.

The plan is proceeding in an orderly manner.

Iron ore ranks first among its basic ores.

No matter what you build, iron ore is indispensable.

If you want to build powerful weapons, you can't do without him.

Looking at this huge iron ore mine, Hongxuan couldn't help but smile.

He once again gave an order to his Qilin Guard and all the soldiers to keep the information about this place strictly confidential.

This place contains a huge amount of iron ore, and this news must never be leaked.

If leaked.

He might really be killed, which was something Hongxuan dared not even think about, even though he now controlled an army of 130,000.

If the huge amount of iron ore here were to be leaked out, not only would the King of Beishang come out in full force.

I'm afraid that Emperor Dingwen Hongjing will not be able to sit still and will definitely get the iron mine here at any cost.
