Ming Dynasty: I, Zhu Gaoyun, inherited the command of Ju Ling.

39: Write a letter to Zhu Di, Zhu Gaoxian is going to plant rubber in the south

Shandong, Qi Wangfu.

Zhu Gaoxu was in his study, looking at the two wall calendars hanging on the wall!

One is the "Great Unification Calendar" used by the Ming Dynasty, which is a calendar specially compiled by Liu Ji and Liu Bowen after the founding of the Ming Dynasty!

The other one is a new calendar compiled by Zhu Gaoxian himself, that is, the chronology of the Common Era!

In ancient times, there was no such thing as a new calendar, which he directly calculated according to the way of some chronological years in later generations, so every time Zhu Gaoxu looked at the calendar, he would take a look at the new calendar!

After looking at it for a while, Zhu Gaoxian took out a brush and drew a circle on a few of the days!

He had to mark the days when he was going to retreat, and he had to keep track of when he was going out!

It's like a New Year's holiday, Zhu Gaoxian definitely has to avoid it, and he won't retreat and cultivate!

After planning the next cultivation plan, Zhu Gaoxian left the study directly, and at the same time, the Li family had already arranged for the people of the palace to prepare today's dinner!

The winter in the north is exceptionally dry and cold.

The wind blew on your face like a knife scraping!

Zhu Zhancheng, the prince of Qi, was wrapped inside and out like a big zongzi, only showing a small face, and was usually watched by the nurse!

Seeing Zhu Gaoxian coming over, the nurse who was holding the prince Zhu Zhancheng hurriedly got out of the way and saluted respectfully!

"No need to be polite!".

"This king will wear something for the prince!".

Zhu Gaoxian waved his hand, and then took out a prepared jade pendant tied with a red rope from his body, and carefully put it on Zhu Zhancheng's neck!

This jade pendant is naturally the same as the jade pendant given to Zhu Di, they are all the same magic weapon!

With this magic weapon jade pendant, at least I don't need to worry about my son's safety!

"Good grandson, your son is still so young, he can also wear this talisman weapon?"

Zhu Yuanzhang's voice rang out at this time.

"Grandpa Huang, this talisman refined by my grandson, even when there is no danger, can also have the effect of consolidating the wearer's foundation and cultivating the yuan, so that they will not be invaded by all diseases!"

Zhu Gaoxian explained with a smile.

"There is still such a function? Now it's cheaper than the fourth!".

Zhu Yuanzhang was somewhat apprehensive when he heard this.

If he could have had such a talisman by his side, maybe he would have lived for a few more years!

"Lao Zhu, look at it!".

"We're all emperor souls now, it's useless to envy this thing!".

Ying Zheng said with relief at this time.

"We just feel it!".

"It's still the fourth child's life, he also gave birth to a fourth, and his fourth child is more capable than our fourth!".

Zhu Yuanzhang couldn't help but sigh.

"Grandpa Huang, grandson is praising me!"

When Zhu Gaoxian heard this, he immediately became happy!

At this moment, the Li family had already prepared dinner, and was beckoning Zhu Gaoxian to hurry over for dinner!

"How's going on with Yantian?"

After Zhu Gaoxian sat down, he picked up the chopsticks handed over by Li and asked directly.

"We've already started to build a tent, and we can bring in seawater next year!"

Li told Zhu Gaoxian about the latest progress of the construction of the salt field.

When Zhu Gaoxian heard this, he nodded with satisfaction!

He is not in a hurry, after all, the amount of work to dig the salt pan is still very large, and this is still ancient, but there is no such convenient electrical equipment in later generations!

"Those who are born are called halogen, those who are boiled are called salt, and the water of the East China Sea is boiled as salt, so as to get rich and the country is satisfied!"

Zhu Gaoxian said slowly, since ancient times, salt has been an important weapon of the country, related to people's livelihood, and is in an important position!

"After digging so many salt pans, there won't be so many people in charge of brining crystal salt at that time!"

Li Shi reminded Zhu Gaoxian with an embarrassed face at this time.

Zhu Gaoxian heard this, but he didn't think so.

He can also understand the dilemma of the Li family, after all, this is in ancient times, even ordinary people know that the crystal salt dried in the salt pan cannot be eaten directly!

It must also be filtered through brine to remove impurities and minimize harmful substances to the body before it can be eaten as table salt!

Of course, with the technology of the Ming Dynasty, at most, it can remove some impurities visible to the naked eye in the crystal salt, and this era does not have the meticulous chemical means of later generations, and it can also analyze the various components in the crystal salt!

"It's okay, this king will write a new recipe for making salt in a while!".

"As long as you refine it according to this recipe, you can refine edible fine salt, and it is finer than any kind of table salt you can see on the market!"

Zhu Gaoxian swore an oath.

"Your Highness still has such means of refining refined salt?"

When Li heard this, he was even more surprised.

"Listen to this king's right, what this king said, when did he break his promise?"

Zhu Gaoxian smiled confidently.

"That's right, Your Highness said yes, then it must be possible!".

Li Shi also laughed when he heard this.

For Zhu Gaoxian, Li also admires it from the bottom of his heart, as a husband and wife, Li also knows that there are too many unusual things about his husband!

is his husband, but he can't speculate on the existence of common sense!

From time to time, you can give yourself a little surprise!

Soon, Zhu Gaoxian finished dinner and returned to his study!

After thinking about it, Zhu Gaoxian directly flicked off the pen and paper and began to write a letter to Zhu Di.

Under normal circumstances, as vassal kings or when it comes to matters in the fiefdom, the vassal kings directly hand over the folds to the court through the long history!

But who made him Zhu Di's own son, writing a letter to Lao Tzu as a son, it is naturally no problem, and it can also bypass the borders of the imperial court, and it can also appear closer!

And the general content of this letter is that Zhu Gaoxian is going to plant some rubber trees in the south and other places, so he needs to say hello to Zhu Di, and also told Zhu Di that this is a good thing for the benefit of the country and the people!

He believes that Zhu Di should still be able to meet his requirements!

As for the role of the rubber tree, it is naturally used to produce natural rubber!

Zhu Gaoxian is ready to tinker with rubber tires in a few years, and if he wants to carry out industrial development, rubber is an indispensable material!

This is also preparing for the future!

"Good grandson, what is this rubber tree?".

Just when Zhu Gaoxian was halfway through writing, Zhu Yuanzhang's curious voice sounded in his head again!

The main reason is that Zhu Gaoxian also said in the letter that rubber is a good thing for the benefit of the country and the people, which also aroused Zhu Yuanzhang's interest!
