With a little apprehension, Zhu Di walked in from outside the hall with a cowhide bag.

When he entered the hall, he raised his head and saw Zhu Yuanzhang staring at him.

Looking at each other, Zhu Di suddenly felt that his legs and stomach began to twitch a little again.

Even a simple glance at him by his old man was enough to make him tremble.

"Son-in-law Zhu Hu, meet your father."

"Son-in-law Zhu Zhen, meet your father."

"Erchen. Son-in-law Zhu Di, meet your father, "

It stands to reason that Zhu Di, as the fourth child, should be the first to see the ceremony.

But as soon as he entered the hall, he was startled by his old man's gaze, and he was slightly stunned for a while.

However, Zhu Hu, who was still on the side, was still able to come to trouble, and took the lead in reminding his fourth brother.

"Your Majesty. Today's matter, I'm afraid I can't think of any good way for a while. Why don't you go back and check the military book first, and see if there is a way to deal with it, right? ”

When he saw that there were three more princes, Xu Da also knew that it was almost time for him to leave.

His Majesty took him for a morning to discuss the matter of facing the north.

However, in the face of this historical trend, the wisdom of the two people is more than enough after all, but not enough.

Not to mention Xu Da's situation. At this time, it is also the time of the last years of the wind and candle.

Some things are even more inadequate.

And at this time, when the three princes came, he didn't have to think about it to know that there must be something that needed to be reported to His Majesty, and it might not be appropriate for him to be by his side at this time.

Especially after experiencing the events in the morning, Xu Da deeply understood this.

There are some things in the future, even if they don't happen, it's not appropriate for you to know.

"Okay, Tiande, you're tired today, go back and rest first. However, when we discussed before, you still thought about it, if you have a way or a clue, tell us as soon as possible, we old guys, we can do as much as we can, and the rest can only be handed over to the juniors. ”

Regarding Xu Da's resignation, Zhu Yuanzhang had no intention of forcing him to stay.

Zhu Di knew that he was unhappy today, but he still turned back at such a time, and he didn't have to think about it to know that there must be something that he had to come to see him.

And this guy left with Chu Ze, and it is estimated that it is somewhat related to Chu Ze's guy.

Let Xu Da avoid it, it may be a good thing for everyone.

It's like a matter in the morning, if the person on the side in the morning is not Xu Da, I'm afraid Lao Zhu won't let him see the sun the next day.

"Your Majesty, Your Highnesses and ministers have retired first."

After getting Zhu Yuanzhang's permission, Xu Da also breathed a sigh of relief.

After bowing slightly to everyone, he turned around and left without looking back.

Looking at the back of Xu Da leaving, Zhu Yuanzhang's eyes narrowed slightly.

But then, he turned his gaze to the three Zhu Di standing in front of the hall, stiff and straight.

"Tell me, you all came to find us together, what's the matter?"

As Zhu Yuanzhang spoke, his eyes couldn't help but look at the cowhide bag that Zhu Di was carrying.

And after hearing his old man's words, Zhu Di breathed a sigh of relief, his father didn't plan to settle accounts with him after the autumn

After knowing that the old man didn't plan to continue pumping him, although Zhu Di was relieved, his tense nerves still did not relax.

He knew that at this time, his father had suppressed the anger in his heart at most.

At this time, he must not be stupid to mention the earlier incident again, otherwise, he will probably be beaten.

After taking a deep breath, Zhu Di respectfully handed over the cowhide bag in his hand to his eldest brother with both hands.

After his eldest brother took the things, Zhu Di spoke.

"Father, because the matter of the feudal domain has been finalized, the son wants to build an ammunition production line outside Nanjing City for the daily training of the escort army and the reserve of ammunition for future fiefdom wars."

"The minister reported this matter to the eldest brother before, and after the eldest brother agreed, the son began to prepare."

When Zhu Di said his plan, he didn't forget to hurriedly report himself in advance, and then began to start preparing for the construction of the ammunition production line.

Although he now has the reputation of being a foreign vassal, he can train his personal guards and train soldiers and weapons openly.

But don't forget, the procedure that should be taken, still has to be followed.

As a vassal king, you must not break the rules.

Especially this one who has a criminal record. It should be regarded as the Yongle Emperor of the later department.

"Father, the fourth brother did show me this matter."

After Zhu Biao heard Zhu Di's report, he also helped to confirm it on the side.

After Zhu Yuanzhang heard Zhu Biao's words, he nodded slightly and motioned for Zhu Di to continue.

"Father, because the new ammunition was improved by Chu Ze, Erchen invited Chu Ze to help Erchen inspect the location of the ammunition production line."

"In this process, in order not to cause financial trouble to the eldest brother, Erchen invited the sixth child to build a production line together, and we took out all the money we had left over on weekdays to build the production line together."

"And in the process, we accidentally discovered a poisonous salt mine, but after Chu Ze confirmed it, he said that the poisonous salt we had always thought could actually be made into edible salt."

"We took some samples, and what the eldest brother held in his hand was the table salt that Chu Ze taught us to make."

"I didn't try it before my son came, I just wanted to tell my father the news quickly, and ask my father to make a decision!"

Before he came, Zhu Di thought about whether he should take the credit for mineral salt on himself.

But after thinking about it, he finally felt that it was better to tell the truth.

His father was such a shrewd man, if he lied about such a thing. Not to mention the credit, once it is seen through, let his father know that he dares to lie in front of him.

It is estimated that all the old accounts in the morning will have to be settled together.

So Zhu Di didn't hide it at this time, and said everything as it was.

Of course, he still concealed the fact that the sixth child had privately formed a caravan.

This thing. It's better not to say it or not to say it.

"What did you just say? Poison Salt Ore can actually be crafted into edible salt! ”

"Yes, father, we have already brought the sample, the production method and steps are detailed, and the sons can also record it later."

"Biao'er, show it to us!"

Zhu Yuanzhang, who was still a little gloomy in the past, suddenly became a little excited after hearing Zhu Di's words.

Salt, like food, is a necessity for the survival of the people.

Compared with grain, the storage and transportation of salt is much more troublesome.

Especially after the salt meets water or tide, it will melt directly, which makes many people have a headache.

It is also because of the necessity of salt and how troublesome it is to transport.

This has also led to the high price of salt.

Especially once someone maliciously hoards, the price of salt will soar to an unimaginable level in a short period of time.

And it was also difficult for the imperial court to control the problem of its price.

Because once the salt panic starts, then the official salt reserves of the imperial court may not be enough.

Almost ninety percent of the salt comes from the coastal area.

This also leads to the fact that the closer you are to the mainland, the more uncontrollable the price of salt becomes.

And now, if there is a new way to obtain salt, it will definitely be a great joy for the imperial court.

"Father, please take a look!"

"Come on, send pen and ink to King Yan."

After hearing Zhu Yuanzhang's words, Zhu Biao hurriedly handed over the cowhide bag in his hand.

And as soon as he turned around, he immediately ordered someone to send pen and ink.

"Fourth, this matter is very important, you hurry up and write down the things."

"Hey, I'll write it."

After hearing his eldest brother's instructions, Zhu Di did not have any delay, and after the workers sent the tables and chairs, pen and ink, he sat down directly and began to pick up the pen and write urgently.

And Zhu Zhen, who also participated in the whole process, also came over, and when he saw that Zhu Di had written something, he would also remind him.

However, when the two of them got busy, Zhu Hu, who was standing aside, was a little embarrassed

When Zhu Di and the others were busy learning technology, he was talking nonsense with Chu Ze

He won't be able to make salt by this means!

And now that he is doing this, standing aside, it seems that he is superfluous.

"Let someone send it to try."

After Zhu Yuanzhang took the cowhide bag handed over by Zhu Biao, he reached out and grabbed a little of the fine salt in the bag, and after observing it slightly, he also sent a little directly to his mouth.

The salty and bitter taste made his brows frown slightly.

But this is not a sign of dissatisfaction, but a natural human reaction.

On the contrary, while frowning, his eyes couldn't help but flash with joy.

"The salt has a strong taste, and it's in excellent condition, and you can barely see the sand and gravel, it's definitely good table salt, if it's not toxic, of course."

Zhu Yuanzhang just tasted it and gave his own evaluation.

Then he directly handed the cowhide bag in his hand to the second tiger on the side, and asked him to bring the things down and find someone to try the effect.

Of course, it is not known who exactly to try it with.

And when Zhu Di finished writing the refining method he got from Chu Ze.

Zhu Yuanzhang also took what Zhu Di wrote with great anticipation, and then checked it carefully.

When you see that the process is simply crushing, making brine, then filtering, sedimenting, and then reducing.

He couldn't help but breathe a sigh of relief.

Originally, he thought that there would be something extremely complicated like refining for seven seven and forty-nine days, or after nine hundred and eighty-one processes.

That's it!

If it is just these simple means, then this poisonous salt mine can't continue to call him poisonous salt now.

Because, if the salt is refined according to Chu Ze's refining method.

It's hard to say whether there is poison or not.

So now we can only call him a salt mine.

As long as you are sure that these mineral salts will not harm your body, then this is a great thing for the imperial court!

"This recipe, you can keep it for the time being. Try the effect first, if it's really edible, then arrange the recipe and let people start learning to make it. ”

"As for the two of you."

Whether mineral salt is toxic or not still needs to be tried before the results can be achieved.

All Zhu Yuanzhang did not jump to conclusions.

Conservative decision-making is something that a superior must consider.

After all, if one of his decisions is wrong, countless people may die.

It's like smallpox. It's still a process of trying.

After the decision was made, Zhu Yuanzhang looked at Zhu Di and Zhu Zhen below.

He also saw the picture just now, when writing about the method of mineral salt refining, Zhu Hu just stood silently aside.

Obviously, he was not involved in this.

And Zhu Di and Zhu Zhen, two brothers, came here today, most likely not just to offer the formula.

After all, this formula was obtained from Chu Ze, if it was just to pass on the formula, Chu Ze could have handed it over to Zhu Biao directly.

"In this matter, regardless of whether the mineral salt is edible or not, the two of you are also considered meritorious. Say, what do you want? ”

When they heard Zhu Yuanzhang's words, Zhu Di and Zhu Zhen's eyes couldn't help but flash a trace of joy.

Originally, if I looked at the meaning of these two people, I ran to his father today and said that it was not good, and I had to ask for a reward myself.

And please reward this kind of thing. There is still a high probability of failure.

And now that his father has spoken, it will be much easier!

"Father, Erchen and Sixth Brother have recently heard that the situation on the eldest brother's side is quite tense. And if we build an ammunition production line, maybe my sixth brother and I don't have enough money."

"What we mean by this is whether we can borrow the veins of the salt mine on the edge of our chosen site for a while. We are by no means trying to make a profit from it, but we are just thinking about the temporary use of salt mine income to build the ammunition production line first. ”

"After that, we don't want this place to produce ammunition, but we just have a place to produce ammunition first, so that it can be used for training and later employment."

"When the time comes to the domain, we won't be able to take away the ammunition field and salt mines."

"Just borrow some for the time being."

"Please also ask my father to fulfill it."

After Zhu Yuanzhang spoke, Zhu Di did not hesitate, and directly put his purpose on the surface.

And Zhu Zhen stood aside the whole time without saying a word.

His fourth brother is going to go to the outside of the territory to become a vassal, but he is not.

It was a little inappropriate for him to follow all the way like this.

At this time, he naturally tried not to open his mouth if he could.

"King Chu, where is your fiefdom?"

"Back to my father, the fief of my son's ministers is here."

Zhu Zhen, who was still trying to reduce his sense of existence on the side, was suddenly named by Zhu Yuanzhang without warning.

And Zhu Zhen was nervous, his head didn't have time to think about it at all, and subconsciously stood up directly to answer Zhu Yuanzhang's question.

However, halfway through his sentence, he realized that something seemed to be wrong.

He hasn't received the order to move his fiefdom yet.

At this time, the fief is set first, this is an ultra vires move!
