A timid voice came. "Taisun...... Your Highness, Xiaomin is done. ”

Zhu Zhanji paused for a moment, looked back at Ma Di at the door, and his heart was full of shock. "You're all done?"

He was not proficient in mathematics in the first place, and the equations he could remember were all familiar to him, and several of them were multivariate equations.

For example, to determine the travel time between Asia and South America, this is not a test on a plane, because the earth is a circle, and two points are not the closest straight line.

It is necessary to consider the change of arc, time zone, and sailing speed in order to accurately calculate the time and arrival time of the two-point straight line.

Even in modern times, it is not easy for a college student to accurately calculate the results under various conditions, let alone people nowadays.

And now, less than an hour has passed, and he has solved all a dozen questions.

Looking at this little guy who was a little cowardly, Zhu Zhanji really had a feeling of being a treasure.

"Bring it to me and show ......"

More than a dozen questions were neatly written out, although Zhu Zhanji couldn't understand some of the ways to solve the questions in the middle, but none of the results were wrong.

In this era, if you want to find people with outstanding literary talents, you can find a lot of them, but there are almost no math masters like Madi.

Mathematics is the foundation of science and plays an irreplaceable role in the development of science and technology.

But in ancient China, although the development of mathematics before the Yuan Dynasty made great achievements. But there is a serious problem, and that is that the over-neglect of mathematics makes it difficult to advance in technology.

It can be clearly seen from the scientific and technological achievements of ancient China that mathematics, like humanities and technology, mostly focuses on intuitive summarization and experience induction, but lacks rigorous thinking and logic.

This is also the fundamental reason why many people evaluate that ancient China only had arithmetic and no mathematics.

It is a sad pity that all those who calculate the calculation can do it, but no one can sort out the corresponding logical relationship.

Therefore, Zhu Zhanji attaches great importance to people like Ma Di, especially since he is still a fifteen-year-old child and has plasticity.

Raising his head, Zhu Zhanji looked at Ma Di, smiled and said, "The lonely young army still lacks a mathematics teaching now, are you willing to come to the young army?" When you come, you will need to study and train with them in addition to being a teacher. ”

Ma Di looked at Ma Zhicai, and hurriedly said, "Xiaomin is willing." ”

Zhu Zhanji nodded and said, "Okay, tomorrow you will move to the farm to live, train with them, and at the same time, prepare your mathematical knowledge system, and teach these young soldiers from shallow to deep." You are only fifteen years old now, and when you tie your hair, Lonely will give you a good future. ”

Zhu Zhanji's young army has now become a fragrant bun, because of the huge role played in the process of the Northern Expedition, nearly 200 young soldiers were all taken away.

But this is not enough, the whole Ming Dynasty does not count the guards, there are more than 270 military guards, more than 1 million troops, plus the guards, the number of troops exceeds 2.8 million.

It is equivalent to saying that the young army has less than 200 people, and even half of the gap has not been filled.

They also noticed that Zhu Zhanji still had more than 400 young troops left in the farm, even if the people of the Bingzi Company were not of great use, but the B-word Company, which had been trained for four years, was now out of the division.

But at this time, Zhu Zhanji refused all without hesitation.

These people can play a far less important role in the domestic battlefield than they can do overseas. Because the terrain of the northern Xinjiang grassland is always known, but if the Ming Dynasty wants to develop overseas, any area needs to be explored from scratch.

Surveying and mapping overseas topographic maps is what Zhu Zhanji attaches more importance to.

Therefore, he will take all these people with him when he goes to Dongying, and first he will map out all the topographic maps of Dongying.

In the future, all of them will be stationed overseas. Countries and islands in South Asia, including Australia, will need tens of thousands of such professional surveyors in the future.

At present, the most powerful learning atmosphere outside of Confucianism in the Ming Dynasty is his young army, they only need to be literate, not to learn the four books and five classics, to learn the knowledge that will be used in life and war.

Let the fifteen-year-old Ma Di teach the young army mathematics at the same time, but also study the curriculum formulated by Zhu Zhanji for the young army, let him receive a new education, and change him ideologically.

Ma Di obviously did not know Zhu Zhanji's purpose and was happy to be valued by Zhu Zhanji. And everything in this warehouse also made him very interested.

When he knew that his uncle would work here in the future to help Zhu Zhanji make various models, he also pleaded: "Your Highness, Xiaomin has been working with his father since he was a child, and he is also proficient in strange skills and tricks, I hope His Highness can allow Xiaomin to serve His Highness with his uncle." ”

Zhu Zhanji did not say yes or disagree, but asked: "Do you really think like those rotten Confucians, these are all tricks and tricks?" ”

Ma Di didn't dare to speak, he looked at his uncle, his uncle was also stunned, Zhou Nan said stiffly: "Ancient books say that this is a strange skill, so Xiaomin also said so." ”

Zhu Zhanji shook his head with a smile and said, "Your request is granted, you should think about this question carefully, and I will ask you again later." ”

At noon, Zhu Zhanji reviewed the training of Yizilian. A group of sixteen or seventeen-year-old young people originally did not have a clear goal in life, but the 200 people of the first company have now achieved a good result, one by one from small soldiers to middle-level cadres in the army, enjoying all the glory.

Their example also inspired this group of young people, as long as they train well, they will not worry about not having a good background in the future, so that these orphans do not want to perform well in front of Zhu Zhanji.

And the special operations training skills they received, topographic mapping techniques, including the use of simple tools to make sextants and perform goniometric positioning, excited Madi, who was seeing this new technology for the first time.

Coming from a family of craftsmen, he was interested in all new technologies and was a good thinker, which is why he came up with the idea of using a prism to increase the effect of the telescope.

The sextant is a simple device, but it includes an academic synthesis of optics, physics, mathematics, and astronomy.

He is different from the members of the young army, who just know what it is, but he wants to know why it is.

He felt as if he had found a new value in life.

Zhu Zhanji's good mood was ruined after receiving a piece of information from Jinyiwei.

On the sixth day of October, that is, the day when the army had just returned to Yingtianfu, the southeast coast of Korea was again plundered by Japanese pirates, and on October 15, his fleet returning to Ningbo from Dongying also encountered pirate ships, although the other party did not dare to attack his ship, but the reappearance of pirates made him also have new worries about the current security of the Ming Sea.

These pirates are now heading south, and no one knows where they will come ashore, and the combat power of these locusts is equivalent to that of the special forces of this era.

The coastal guards are equivalent to the militia of this era, so it is still difficult to rely on the militia to deal with the elusive special forces.

He looked at Cao Xu, the head of the Jinyi Wei Qian, who sent the letter: "Where is the commander now?" ”

"Your Excellency has already entered the palace after receiving the information, and asked the lowly to come and deliver a message to His Highness."

The review was basically over, and Zhu Zhanji said to Chen Li: "The results of the young army's training are still satisfactory to Gu, kill two pigs today, and give the soldiers more food at night." Today, the top three in each individual item will be rewarded with two taels of silver each, and the rest of the soldiers will be five hundred dollars each. ”

When all the soldiers heard this, they were overjoyed, and they bowed down neatly to thank Zhu Zhanji.

After arranging the affairs of the farm, Zhu Zhanji took the Ma family's uncle and nephew back to the city together. After the Donghua Gate was separated, Zhu Zhanji returned to the palace with some eagerness.

He has been thinking about how to attack Dongying, and wants to find an opportunity to attack Dongying. Without a suitable excuse, he will attack Dongying, not to mention the Minister of Civil and Military Affairs, even Zhu Di will not agree.

And now he doesn't have to create it on purpose, the opportunity has come.

As long as he can convince Zhu Di, he can take this opportunity to launch an operation against Dongying.

And Zhu Di is not difficult to convince. Although Dongying is a country that is not conquered, as long as there is a fig leaf, Zhu Di will not hesitate to do it.

Because on the globe, the silver mountain marked by Zhu Zhanji made him excited.

When they were on their northern expedition, the spies of Jinyiwei had already found the silver mountain in Izumo Province, although it was not sure whether the reserves were as big as "Magellan" said, but it was enough to make Zhu Di's heart move.

With that silver mountain, the Ming Dynasty will never be short of silver in the future.

As soon as Zhu Zhanji entered the palace gate, he asked Wang Li, the Han general on duty: "Has the commander left the palace?" ”

"Your Highness, the commander is in the Wuying Palace, and he has not yet left the palace."

Zhu Di's whereabouts, except for the personal eunuch, no one can snoop on it, nor can he deliberately ask. But since Ji Gang has entered the palace and has not yet gone out, it is okay to ask him about his whereabouts.

Dafa sent two masters back, Zhu Zhanji took Li Liang and them along the alley by the small river of the palace to the Wuying Palace, but found that there were still many civil and military ministers here.

At this time, Zhu Zhanji, as the grandson, could not enter, so he could only hold his mind and return to Xingqing Palace first.

But when he left, he left Li Liang behind, and only he was qualified to talk to Zhu Di.

"Jin Daban, bring me all the information about Dongying, and I have to read it carefully."

After a while, Jin Kuo took eight little eunuchs and carried out four boxes of materials. "Your Highness, all the information about Dongying is here, one box is reported by Jinyiwei, and the other three boxes are the information collected by the internal supervisor during the past trade with Dongying."

"Arrange a few more people to find out the information about Izumo Province, the Muromachi Shogunate, and the Wako."

(Entering the mountain today, tomorrow's update may be delayed, first ask everyone for leave, stay in the mountains and settle down, the old demon concentrates on coding words.) ）
