Following.

The sky was still dark, with the moon and stars twinkling faintly.

Zhu Xiongying, who had slept lightly for an hour, had already gotten up and jogged for half an hour, he slowly stopped and took a deep breath: "If it is pure health, jogging can lead to longevity and internal organs, but this is not enough, I will at least leave Daming a foundation that is enough to support Daming's strength for five hundred years, mathematics, physics, gunpowder, musket ......"

"My Chinese nation is industrious, brave, and intelligent, why will it lag behind the West in later generations? The people's wisdom has not been opened, why has the people's wisdom not been opened? The people's livelihood is not rich, why is the people's livelihood not rich? Officials cure diseases, but there is not enough land! If we can achieve a vast land and rich people, we will surely shine among the nations of the world in the future......"

In his mind, he counted the book he had written last night, and there were many things he had missed.

There are many policies that have not been determined in the Ming Dynasty, and this is the best time.

Many things are to lay a good foundation at the beginning, such as mathematics, if the imperial examination is added to the official department, mathematics, but also professional theory, then at least to leave a ladder for all kinds of specialist talents, medicine must also be very concerned, as well as engineering......

"Qi Minzhi is a double-edged sword, and now the Ming Dynasty has decided at the beginning of the Ming Dynasty, and it is indeed a difficult thing for the northern officials to be corrupted like this."

"The key now is to protect the people's livelihood, and in five years, most of the people who can be mastered by the emperor can eat enough, so that they can consider gradually enlightening the people's wisdom, otherwise in the current situation in the north, Zhejiang, Jiangxi, Fujian and other places are rampant, and no trouble will be made."

Thinking of the current situation in the north of the Ming Dynasty, Zhu Xiongying couldn't help frowning.

Yanyun Sixteen Prefectures, from the beginning of Shi Jingjiao's cession to the Khitan, left behind for more than 440 years, in fact, to be strictly calculated, from the Anshi Rebellion, An Lushan occupied Hebei, the north has sunk, and later the north has gone through the Liao State, the Jin State, the rule of the Mengyuan Dynasty, and the customs and culture of the south have been very different, four or five hundred years, can change a lot of things, now the north of the land is full of castles, the villagers are like wolves and tigers, the people and clans are self-reliant, if you want to rule, you have to work for dozens or hundreds of years.

Moreover, this requires a strong, unified, and highly effective policy implementation of the Ming Dynasty.

It is necessary not only to have strong and arbitrary means of force to convince the people, but also to have good material logistics, especially grain, which can make the common people in the north have enough to eat, and many things can be easily solved.

The Southern Literary Party, at the moment has a lot of power, and is good at calculation, if you open the wisdom of the people, bring some later theories in advance, I don't know what kind of moths this gang of literary parties in the south will make, the emperor's grandfather Zhu Yuanzhang once personally ordered, prohibiting Suzhou and Songjiang people from being the head of the household book, its original words are "the household of the Xu officials, as much as the eastern Zhejiang giant traitor, in the middle of the cave, move up and down, do their best, and be good at calculating, depending on the chief puppet!" In the previous life, this policy was lifted after Zhu Yunwen came to power, so officials in Jiangsu, Zhejiang, Shanghai and other places were crazy about Zhu Yunwen.

It is not so much that the Battle of Jingyan was a power struggle between the Ming royal family, but rather a war related to the distribution of interests and the imbalance in the distribution of power between the north and the south.

Now in the court, the Zhejiang Party, the Chu Party, and the Qi Party have faintly taken shape.

Most of the core of the Chu Party now depends on Chen Youliang's Han State ministers and generals, which have not yet been revealed, but the Qi Party in the north, with the intentional support of Zhu Yuanzhang, seems to have some power.

"Little master, drink saliva."

Zhu Xiongying was in a daze, and Zhou Kuan on the side handed over a bamboo tube of soaked wolfberry water.

Zhu Xiongying was stunned.

When he looked back, not only Zhou Kuan, but Zheng He also woke up.

Zhou Kuan was better, Zheng He's eyes were dark circles, and Yuhe, the maid who served him personally, was also sleepy-eyed, but they all looked at themselves fixedly, their eyes were clear.

Last night, they stayed up all night with them......

"Little master, you have written a book all night and slept for less than an hour, so let's rest."

The maid Yuhe persuaded softly and pursed her lips.

"Even if it's a body made of iron and copper, I can't help staying up all night."

Zhu Xiongying smiled and said, "It's okay, it's not in the way." ”

He raised his head and glanced at the big rooster who had just come out of the chicken pen and jumped up the steps excitedly to crow, and secretly said in his heart, not to mention anything else, he had to continue to work hard if he didn't finish writing Daming's land reform policy and didn't leave Daming enough textbooks to enlighten his engineering foundation.

"You just got up, Zheng He, you take this book to study in good students."

Zhu Xiongying took out a book and handed it to Zheng He.

Basic Mathematics Education.

Zheng He took the book, flipped through it, a little confused, the numbers in this book are unheard of, unseen, just because the numbers in this are the Arabic numerals written by Zhu Xiongying, and the current Arabic numerals are quite different, the Yuan Dynasty had a large number of people who did business here, bringing the original Arabic numerals, but the Chinese merchants and mathematicians still like to use the "Suzhou yards" and calculations, because the Suzhou yards and calculations are still very advanced at this time.

Even in the fifteenth year of Hongwu and a long time in later generations, Suzhou yards and calculations are still advanced mathematical symbols, and the popular Arabic numerals in later generations and the popular Arabic numerals now, there are obvious differences, which have experienced several generations of evolution, and are the self-evolution of Chinese and Western businessmen and mathematicians in the process of communication and use.

In the previous life, it was not until the middle and late Qing Dynasty that foreigners began to control the customs of the Qing Dynasty, and Arabic numerals began to be popularized in large numbers among the people. Prior to this, the mainstream Chinese Suzhou yards and calculations were widely used in the fields of business and mathematics and astronomy. But in fact, Arabic numerals have begun to appear in the Song Dynasty, and by the time of the Yuan Dynasty, the Qin Tianjian of the Yuan Dynasty and the merchants of the Yuan Dynasty used a lot of them, and they were not popularized among the people.

At this moment, there are still many Semu people in the Qin Tianjian of the Ming Dynasty, and they combine the Suzhou yards of Huaxia, and plan to add Arabic numerals to modify, and compile many new Suzhou yards, which are very close to the Arabic numerals of later generations...... These mathematical symbols were then brought around the world by the Colours and Arab merchants who were doing business in various places, and by sea vessels......

Learn mathematics, physics and chemistry well, and you will not be afraid to go all over the world, this is not false at all.

"This symbol is somewhat similar to the Shah number, and it is not the same as my Ming Suzhou yard."

Zheng He flipped through and said.

"These numbers look at now, it doesn't seem to be as popular as Suzhou yards and calculations, but in later generations, it will be prosperous, first, it is simple to apply, and the yards do not need to be converted, second, this number is simple to write, three or five years old children can learn, and there are matching formulas, I will teach you, you have to learn well."

"Arithmetic is the foundation of navigation, without mathematics, navigation is difficult, I really don't know how Yongle went to the Western Ocean seven times in his previous life, how to solve various problems in ocean voyages? The equatorial ecliptic, the angular deviation, the latitude and longitude lines, the navigation clock, the height of the mast, the angle of the canvas, the power configuration of the ship, and the allocation of supplies and supplies for the logistics vessels all require extremely high mathematical attainments and knowledge of astrophysics......" Zhu Xiongying muttered in a low voice.

"Little master, the slave must study hard!"

Zheng He closed the book, looked at the book that Zhu Xiongying had worked so hard to write last night, and said seriously.

……

After breakfast, Zhu Xiongying went to greet the crown prince Zhu Biao and stepmother Lu Shi.

Zheng He and Zhou Kuan both followed behind Zhu Xiongying, Zhou Kuan bowed down, and whispered: "Little master, Commander Mao sent a letter to the people, but the few servants of Zhu Tan, the king of Lu, who came to offer gold and stones, were a little dirty behind them, and they suspected that they were related to the spies in the north. ”

"Spies from the north?"

Zhu Xiongying frowned.

At this moment, the Northern Yuan forces are still very strong.

Not to mention anything else, let's just say that Yunnan, which has just been recovered, the remnants of Mengyuan's forces, in the case of being defeated by Fu Youde Lanyu Mu Ying with more than 300,000 people, can still gather more than 100,000 troops in Yunnan, taking advantage of the need for the Ming Dynasty to guard the main roads, and when the guards are divided into various places, they stormed Kunming, if it were not for Mu Ying to lead the troops back in time to help, Kunming would have fallen.

Not to mention the northern land, that is, under the nose of the Northern Yuan......

Among them, especially Gansu, Shaanxi and other places were the most heavily invaded by the Northern Yuan, these two areas are closer to the north of the Saiwai Desert, and the battle line is extremely long, the spies of the Northern Yuan Dynasty come and go at will, infiltrating all walks of life in the Ming Dynasty.

"Got it, I've got my own plans for this."

Walking into the main hall, his father Zhu Biao and stepmother Lu Shi were eating, and the difference from last time was that not only Zhu Yunwen was there, but Zhu Xiongying, who was only three years old, was his younger brother, and the third Zhu Yunxi was also sitting on the table.

"Big brother!"

Zhu Yunwen was eating in a regular manner, and when he saw Zhu Xiongying, his eyes lit up.

And Zhu Yunxi also giggled at Zhu Xiongying and waved at him.

However, Zhu Yunxi obviously has a big tongue, his speech is slurred, and the few times he calls his brother is not so clear.
