And if primary and secondary school textbooks are sacred books, even if the perfect modern education system is unimaginable for ancient times.

The development of Western civilization was first established on the education system.

More precisely, everything about Western civilization is based on its university system.

Since the European Reformation in the 16th century, the Protestant countries have taken education as an important means to win over young people, promote new religions, and fight against the forces of old religions, and force children to enter school to learn to read, write, and go to school, and began to lay the foundation.

However, the plundering of the whole world in the Age of Discovery caused a large amount of wealth to pour into Europe, and Europe used this wealth to construct their own unique system.

This can be seen in Germany.

During the First World War, Germany was almost disabled, but after a hundred years of compulsory education, Germany only had the capital to sweep the world in less than a few decades, even if it was disabled again in World War II, it still rose in the new era.

The education system sent by Jiang Chen to Zhu Di and Zhao Yu not only has the introduction of the modern education system, but also has the role of the modern education system.

For Zhu Di, Lu Xiufu, and Zhang Shijie, they may not see what this modern education represents, but they can see that under the modern education described in the article, there are extremely powerful countries.

Great Britain, Germany, island nations, and even China.

Even the few descriptions between the lines make people feel a tingling of the scalp.

It even makes their hearts surge.

At this moment, whether it is Zhu Di of the Ming Dynasty, Lu Xiufu of the Great Song Dynasty, and Zhang Shijie, they all desperately hope that the country will become stronger.

Needless to say, the former, as the Emperor of Yongle, Zhu Di's pursuit has always been only the highest, not higher, and the latter, in the case of the destruction of the country by Meng Yuan, is also eager to restore the Great Song Dynasty and restore China.

In this way, the content described in this article is undoubtedly extremely attractive to them.

No, it's not just attractive.

It's a heartbeat.

And it's more exciting than before.

Because the modern education system almost tells them a path that can completely enrich the country and strengthen the army.

Everything is more straightforward than before.

The only problem is that the cost is almost a horrible amount.

"Compulsory education!"

"Come on, give me Xia Yuanji, the secretary of the Xuanhu Department, and the prince Zhu Gaochi!"

Daming, Taihe Palace, Zhu Di slowly put down the manuscript in his hand, his eyes couldn't help flashing, and then he quickly spoke.

"No!"

A eunuch quickly responded.

And soon, Xia Yuanji and the crown prince Zhu Gaochi quickly arrived at the Taihe Palace.

"Your Majesty!"

"Father!"

Xia Yuanji and Zhu Gaochi quickly saluted.

"No need to be polite!"

"I have a law today, but I can rejuvenate the foundation of the Ming Dynasty, Xia Yuanji, prince, take a look!"

Zhu Di waved his hand.

Soon there was a eunuch who handed the things in Zhu Di's hand to the prince.

Hearing Zhu Di's words, the prince was a little shocked, and Xia Yuanji's heart moved, and his eyes involuntarily looked at what the prince had taken, a little excited.

And Zhu Gaochi took the book with some doubts and began to flip through it.

And at this look, Zhu Gaochi couldn't help but fall into a trance.

It wasn't until a moment later that Zhu Gaochi suddenly raised his head and looked at his father with a shocked expression.

"Father, what is this?"

Zhu Gaochi opened his mouth, his heart couldn't calm down at all at this moment, and his mood fluctuated even more violently.

What he saw made his breath stagnate.

"His Royal Highness the Prince, can you give the minister a look!"

Xia Yuanji, who was waiting, couldn't help but speak.

"Lord Xia, give!"

At this moment, Zhu Gaochi reacted and hurriedly handed the book to Xia Yuanji.

Xia Yuanji also hurriedly looked at it.

On the dragon chair, Zhu Di did not answer, but waited for Xia Yuanji to finish reading.

A quarter of an hour later, Xia Yuanji finished reading the book, and his heart couldn't help but fluctuate violently, and his scalp was also numb at this moment.

looked at Zhu Di, and looked at the prince's gaze,

Xia Yuanji took a deep breath before slowly speaking.

"Your Majesty, this method can indeed benefit me for all generations of the Ming Dynasty, but the cost of this method is probably hundreds of millions of dollars, and the cost will be even more in the future, and I will be able to support it in the Ming Dynasty."

As a scholar of the household department, and after the washing of the monetary theory, Xia Yuanji naturally quickly discovered a big problem in modern education.

It costs too much.

That's right, it's too expensive.

Compulsory education, allowing all children to go to school, this seems to be beautiful, almost no less than the Datong society, but the problem is that the state may not be able to support it.

How many people are there in the Ming Dynasty, with more than 12 million households, in fact, the population may have reached tens of thousands, so how many children are needed to educate, millions, or even tens of millions, how much money is needed.

And as the population grows, the amount required will be even larger.

Even if Daming's finances have begun to skyrocket at this moment, they may not be able to support it.

"Father, what Lord Xia said is extremely true, Erchen thinks that it is enough to open schools in various places and open education widely, why do you need to do this?"

Hearing Xia Yuanji's words, Prince Zhu Gaochi also hurriedly spoke.

This kind of cost is so terrifying that even thinking about it makes people tremble.

Prince Zhu Gaochi was almost worried about money a few years ago, and he instinctively felt resistant to taking out so much at once.

"It's okay, this cost can be from the private treasury, not from the national treasury!"

Zhu Di waved his hand and said something that made the crown prince Zhu Gaochi and Xia Yuanji frown.

Especially Natsuharaji.

During this period of time, hundreds of millions of taels were taken out from the emperor's private treasury, but at this moment, His Majesty the emperor actually said that he could still come out of his private treasury, and at this moment Xia Yuanji felt that he was in cardiac arrest.

And the crown prince only felt dazed.

What does his private treasury look like, how he is not clear as the prince, how can he take it out.

"Father, I'm afraid it's hard to afford this private treasury!"

Zhu Gaochi couldn't help but speak.

"You don't have to worry about this!"

"My royal private treasury today is not comparable to the original!"

"Natsuhara-yoshi!"

Zhu Di waved his hand, and then looked at Xia Yuanji.

"The minister is here!"

Xia Yuanji hurriedly saluted.

"I need this education not to start with Confucianism, but to enlighten the people, you can formulate a strategy for me in the next few days!"

Zhu Di patted the textbook on the bookcase and spoke towards Xia Yuanji.

"Not Confucianism?"

Xia Yuanji and Zhu Gaochi couldn't help but be stunned for a moment, and their eyes involuntarily looked at the tall book in front of Zhu Di's eyes, and their expressions were a little puzzled.
