That day.

Fang Bin put down everything at hand, and directly took His Royal Highness Taisun to the iron smelting factory of the Ministry of War.

There are dozens of these iron-smelting plants.

They were all used to build weapons for the imperial court.

Zhu Zhanji saw these more than ten iron-smelting plants, shook his head with a smile and said, "I don't want so many, I only need one." ”

"Don't stop the rest and continue to produce."

Fang Bin nodded: "Okay." ”

With that, he hurried to command.

Soon, he came back and respectfully bowed his hand and said, "Your Highness, I have already done it according to your instructions. ”

"Tomorrow, this best iron-smelting plant will be vacated. ”

As he spoke, Fang Bin pointed to the ironworks at the front.

Hearing that it could double the hardness of the weapon and improve the quality of the weapon, Fang Bin was very excited, because once it was made, although their military department did not have merit, it could also save a lot of effort in future wars.

Zhu Zhanji smiled and nodded: "Okay." ”

"In addition, blacksmiths, I will go to prepare for the transfer today, and it will be ready tomorrow, and I ask His Royal Highness Taisun to wait a while."

As he spoke, Fang Bin was already a little excited.

Zhu Zhanji bowed slightly: "Okay." ”

In my heart, I took a deep breath.

Zhu Zhanji doesn't know if he can restore the iron smelting method of his previous life, but as long as he can restore it, then the weapons of the Ming Dynasty will far surpass all countries by a big step!

Thinking of this, a smile appeared on Zhu Zhanji's face.

As long as it can be manufactured, it can also provide a great boost to the future of the southern and northern wars.

Of course, the main purpose is because of this.

……

Early the next morning.

Zhu Zhanji came to this iron-smelting plant early.

In the iron-smelting plant, there are already hundreds of blacksmiths waiting for Zhu Zhanji.

Seeing Zhu Zhanji coming, the blacksmiths hurriedly saluted and shouted to my lord.

Fang Bin did not tell them the identity of His Royal Highness Taisun, but asked them to call their lords.

Zhu Zhanji bowed slightly, looking at the hundreds of blacksmiths: "You all know how to strike iron?" ”

The blacksmiths nodded.

Zhu Zhanji laughed: "If you know how to strike iron, come and try my method to see if you can improve the quality of iron by another level." ”

Zhu Zhanji said, taking out a drawing from his arms.

On this drawing, it is the forging of the method of iron smelting.

Among them, there are many raw materials, about various elements.

As long as these elements are added, the iron can become harder, but Zhu Zhanji didn't know what kind of element it was for a while, so he casually matched some.

For a while, hundreds of blacksmiths came up to watch.

Looking at them, their faces changed slightly.

Zhu Zhanji was overjoyed in his heart and said with a smile: "What? Think it's possible? ”

Those blacksmiths raised their heads and looked at Zhu Zhanji with a confused look on their faces.

"I don't understand."

"I don't understand."

"What is an element?"

The heads shook like rattles, which made Zhu Zhanji's original smile a little solidified, and he couldn't laugh anymore.

These elements were really a bit difficult to understand in ancient times.

Zhu Zhanji took a deep breath and carefully explained these elements to them.

If you want them to improve their iron quality, you have to tell them what the elements are and what kind of elements they add to the iron to make the iron stiffer.

It's just that it was taught for a day.

At the end of the day, there was no progress.

That's it.

Zhu Zhanji returned to the palace, and on the morning of the sixth day, Zhu Zhanji returned and continued to teach the blacksmiths.

And at last, there was a more clever blacksmith who understood a little, so he tried to add other things to the iron to make it.

It's just that he failed.

For the first time, quicklime was added, and the entire furnace crackled, almost thinking that the furnace was going to explode.

The second one added sulfur and salt to it.

Without exception, it still didn't work at all.

The smelted iron turned out to be pieces of scrap iron, not to mention hard, and it was difficult to smash a dog to death.

Zhu Zhanji's face darkened a little.

For the next few days, everyone continued to experiment one by one.

These experiments are all relatively high-risk in nature.

In just a few days, several of them were injured and sent to the doctor.

However, Zhu Zhanji is more energetic than this new method of iron smelting, so he will not give up if he does not achieve his goal!

The blacksmiths also became cautious one by one.

I started to study it slowly, and I didn't dare to add anything to it at will.

And Fang Bin often comes over from time to time to take a look, obviously he is very concerned about this matter and attaches great importance to it.

It's like before, for the manufacture of firecrackers.

Because once it is made, it will be a change that transcends the times.

……

And these days.

The party in eastern Zhejiang began to be active again.

As far as Zhu Zhanji is concerned, the Zhedong Party will be eradicated sooner or later.

And the Zhedong Party also felt that once the Taisun was put on the throne, he would never let go of the Zhedong Party.

Therefore, the Zhedong Party has been looking for an opportunity!

They have been longing for this opportunity for a long time.

Now, the opportunity has been found.

His Royal Highness Taisun was in the Ministry of War, and asked for an iron-smelting plant in the Ministry of War, and he also appropriated hundreds of blacksmiths, if it succeeded, it would be enough.

But what if it fails?

His Royal Highness Taisun can be regarded as hindering the military department and delaying the major affairs of the military department, this is to be held accountable.

And once His Royal Highness Taisun succeeds, this will be another huge blow to their Zhedong Party.

Therefore, Taisun can only fail!

Can't make it!

With such thoughts, Hu Rong's mind began to become active again.

In the past few days, he has been trying to find a way to infiltrate it.

Let's see if there is any way to do some damage to Taisun's iron-smelting manufacturing.

This is the case with party struggle, competing for interests, even the slightest.

On this day, the military department gave the matter.

In fact, it has nothing to do with the military department.

It's just that according to the six departments, it is divided into military departments, household departments, etc.

In the middle of the military department, Hu Rong sat in the main seat and was thinking about something.

Not long after, a voice suddenly came from outside.

The voice was loud.

"Master Hu, I have brought back a blacksmith from that ironworks."

The sound was full of a hint of surprise.

When Hu Rong heard this, his eyes also showed surprise.

Then he hurriedly looked out the door.

Soon, a man dressed as a blacksmith walked in outside the door, as well as Yao Lin, the deputy of the military department.

Yao Lin looked at Hu Rong with a smile on his face: "Lord Hu, I brought him to you." ”

Hu Rong looked at the blacksmith and asked in a deep voice, "Are you working in that ironworks?" ”

The blacksmith nodded hurriedly: "The villain is exactly." ”

Hu Rong smiled: "Help me destroy them, as long as you succeed, I will let you have no worries about food and clothing in this life, and promote you to become the head of a county." ”

As soon as these words came out, the blacksmith's eyes lit up.
