In a class that lasted for half an hour, Zhu Yuan explained the principle of the formation of tides, and answered all kinds of strange questions from everyone in the hall. Liu Lian, a group of you are better in astronomy and mathematics than me, my request is that through the calculation of the trajectory of the moon, a tidal schedule will be made every month in the future, including when the monthly tides will appear, and the exact time of high and low tide every day, which cannot be the simple judgment of the coastal people, and must be accurate to the range of a quarter of an hour, for the reference of the seafarers, is there a problem? ”

Yes!

Liu Lian wanted to say that there were too many questions he wanted to ask, how could this short class time be enough!

However, in the face of Zhu Yuan's serious expression, Liu Lian temporarily suppressed all kinds of doubts in his heart, did not interrupt, and nodded seriously: "Hanlin, there is no problem with the lower officials." ”

Even without Zhu Yuan's explanation, the ancients also mastered the accurate law of the moon's waxing and waning through long-term observation.

Now, knowing the reason, for a group of the top mathematicians and astronomers of the era, it was not a problem to calculate the exact tide times of the month or even the day.

Zhu Yuan nodded with satisfaction: "It's no problem to think about it, let you predict the weather, although a group of people can't compare to a Liu Laoqi, but the weather is too unpredictable, and it is understandable." The tides are regular, and if you can't do it, I'll have to drive you all back to Jinling. ”

Liu Lian couldn't help but smile bitterly, and thought of the old man surnamed Liu who Zhu Yuan had recently recruited.

Liu Laoqi, a native of Cixi, Mingzhou, has no big name, ranks seventh in the clan, is called Liu Qi when he was young, and was ridiculed for having the same name as the big poet of the Song Dynasty.

Now that he is old, he is called Liu Laoqi.

Liu Laoqi has had an instinctive instinct to predict the weather since he was a child, and the accuracy rate is very high. Because of this magical ability, it is said that the fishing village where he was born was born in the more than ten years when he was a child, the villagers went out to sea to fish, and there was no accident because of the storm, because they could always avoid it.

Such a miraculous ability was of course noticed, and Liu Laoqi was only nineteen years old when he was invited to sea by a maritime merchant. However, it was only the first time to go to sea, and the fleet unexpectedly encountered a storm, and only a few people such as Liu Laoqi survived.

Liu Laoqi thought that he could always predict the weather and angered the Dragon King, so he had that catastrophe back then, and after escaping back, he directly changed his livelihood, moved away from the seaside, and turned to farming.

However, over the decades, this ability has not been lost.

The Yinghai Division openly recruited all kinds of navigation-related talents from the people, and Liu Laoqi's son sent his father to recommend himself, and he made several predictions these days.

All-in.

Zhu Yuan fulfilled his promise yesterday and planned to give the other party a positive eight-grade product, but the old man said that he would consider it.

I haven't replied yet.

Since he mentioned it, Zhu Yuan didn't think that the old man would refuse his award, so he took the opportunity to say to Liu Lian again: "Although Liu Lao judged the weather largely by some elusive sixth sense, his own experience over the past few decades can still be summarized and compiled into a book. Liu Lian, you take the time to talk to him. ”

Liu Lian agreed again.

After saying this, Zhu Yuan glanced at the wide vertical board full of 'PPT', confirmed that everything that should be said, then clapped his hands and said to everyone: "That's all for today, class is over." ”

After a little waiting, no one shouted 'goodbye, teacher'.

The ancients......

No politeness!

When everyone got up and started to walk out, Zhu Yuan instructed Li Gui to rearrange the series of courseware just now, and in the future, it would be the teaching materials of the Ying Hai Division, and he came to Qiao An, who was sitting at the same table with Li Zhen, the fourth elder of the Li family.

Last time, he went to sea with Hua Gao and found the pirates, Qiao An not only led his team of 100 people as the vanguard, but also captured the first pirate thief and made the first contribution.

However, I also suffered some minor injuries and has been recuperating recently.

Seeing Zhu Yuan coming, Qiao An and Li Zhen hurriedly stood up.

Zhu Yuan didn't speak, but just took Qiao An's notes and flipped through them, hmm...... Back in this era, I finally saw a word that was more ordinary than my own.

Regaining some self-confidence, Zhu Yuan softly mentioned Qiao An a few words, and told him to ask the Li brothers for advice if he had any questions. After saying a few words, he noticed that Fang Li was still here, signaled, and walked out of the classroom first.

Fang Li only returned from Taizhou yesterday, bringing back more than 2,000 people.

Transferred to the next room, which is Zhu Yuan's private office. As soon as he entered the door, before Zhu Yuan could speak, Fang Li knelt down: "My lord, my father asked me to thank you for saving the other party's life, and my father also said that in the future, the Fang family will be sent by the adults to go to the soup and fight the fire, and they will never give up." ”

Zhu Yuan was a little surprised.

After Fang Li paused several times in a row, he fell to the ground and realized that compared to the time when Fang Li knelt down and begged him to help say good things in Jinling, this time was obviously different.

After a moment of silence, Zhu Yuan said, "You get up." ”

After speaking, he turned to the desk and sat down, looked at Fang Li, who got up opposite, and asked, "How is your father doing?" ”

Fang Li bowed slightly, and said, "My father was awarded the Zuo Cheng of Fujian Province by His Majesty, and he didn't know the official. ”

Zhu Yuan said with a smile: "Very good result, enjoy the evening happiness with peace of mind in the future." The future of the Fang family will fall on you. ”

"My lord, I have two younger brothers, if my lord needs to ......" Fang Li said again, suddenly reacted again, and hurriedly said: "...... I don't have to give any official position, but I want to be driven by adults. ”

Zhu Yuan shook his head: "It can't be like this, it's easy to see that your Fang family is eager again, let them rest assured for a few years." Also, on your father's side, don't change your attitude when you get an official position, you still have to take the initiative to greet Your Majesty occasionally in the future, if it is the birthday of Your Majesty and Niangniang, or other things, you can't ignore it. ”

"Remember the teachings of the adults, and the lowly will immediately let people go back to Jinling to spread the word to their father." After Fang Li said this respectfully, he said: "My lord, my father asked people to bring some gifts, not anything valuable, but the books and charts that my father collected in order to talk to His Majesty, hoping to give them to your lord to express his gratitude." ”

Zhu Yuan smiled and nodded: "Then let someone send it." Oh, today happens to be my birthday, so it's a birthday present. ”

Fang Li didn't expect this turn, and immediately knelt down again, kowtowed, and said: "Congratulations on the birthday of the adult, I wish the adult happiness like the East China Sea, and longevity than Nanshan." ”

Zhu Yuan: "......"

How do you feel like you're in your seventies and eighties?

I might as well wish me to be tall and handsome, and to be able to live for a long time.

After saying a few more words, he told Fang Li not to spread the news of his birthday, and he didn't want to make a noise.

Waiting for Fang Li to leave, Zhu Yuan asked people to invite a few old people who had recently been involved in the sea, and called Li Gui to be in charge of the record, and just talked about a few teas, Zuo Qi hurriedly came and stood at the door to report: "My lord, General Wu has arrived, and Lord Hua sent someone to ask, do you want to go to the dock to have a look?" ”

General Wu?

Zhu Yuan reacted for a while, and then remembered that it was Wu Zhen, the deputy governor of the navy appointed by Lao Zhu.

Hua Gao said before that Wu Zhen may not arrive until March, but today, it happens to be more than ten years, and it seems that Wu Zhen has a good ride.

What's more, as soon as Wu Zhen's 20,000 people arrive, as well as the ships that come with him, the matter of transporting grain can be accelerated.

Zhu Yuan is not obvious on the surface these days, but occasionally there are always dishes and faces in his mind, as well as the simple but cruel sentence 'starved to death many people'. Transporting grain to the north a day earlier, Zhu Yuan even felt that he could make up for the days when he was snatched away by those guys who always knelt down to take his life.

Thinking so, Zhu Yuan got up, instructed Li Gui to entertain several old people, and hurried out.

Not to mention anything else, even if Lao Zhu spoils himself again, the number of courtesies he should have must not be less, and he must go to greet him in person.

Take a sedan chair all the way to the east pier of the city.

It was early, and Wu Zhen had not yet come ashore.

However, standing side by side with Hua Gao on the bank of the Yongjiang River, looking at the hundreds of large and small sea boats coming on the surface of the near ocean, Zhu Yuan felt for the first time what it means to have sails like a forest, covering the sky and the sun.

Hua Gao put his hands in his hands, and his tone was also full of emotion: "The Wu brothers are better than me Lao Hua in governing the army. ”

Zhu Yuan didn't answer this, but he understood.

The Wu brothers, Wu Liang and Wu Zhen, both brothers are from Dingyuan, and they are among the twenty-four generals of Huaixi who are the most descendant of Zhu Yuanzhang.

And, if memory serves, both brothers died well.

It's not easy.

Moreover, Zhu Yuan recalled a little, and remembered more.

In the course of the chaotic war in the south of the Yangtze River, there were two people on the eastern front barrier of Western Wu, Wu Zhen guarded Jiangyin, Geng Bingwen guarded Changxing, one north and one south, guarding the key passes, so that Zhang Shicheng could not move westward, and Zhu Yuanzhang had no worries when he marched west to Chen Youliang.

Hongwu was a great hero for three years, Wu Zhen was the Marquis of Jiangyin, and Geng Bingwen was the Marquis of Changxing.

Geng Bingwen also survived the Hongwu Dynasty and the Battle of Jingyan, and once became the commander of the Southern Army, and was ordered to crusade against King Yan. It's just that then the ending is a little unclear.

Let's talk about the Wu brothers.

Since Hua Gao only planned to work for three years, Lao Zhu chose Wu Zhen as the deputy governor of the navy, and his intention was also very obvious.

Zhu Yuan thought about it, but he was curious about the other one, and asked Hua Gaodao: "My lord, where is Wu Liang in the army at the moment?" ”

When Hua Gao heard this question, his expression was a little strange, and he smiled: "Wu Liang, that's a thoughtful person." At that time, he guarded Jiangyin, did not love wealth and silk, had no intention of beauty, was diligent in training troops every day, listened to Confucian lectures in his spare time, and also set up schools, encouraged Tuntian, and reduced taxes, so that Jiangyin was united in one mind, so that the Zhang family did not dare to look east. The lord praised him as the current Wu Qi, and Song Lian praised him as a poem. Zhang Shichengping and Wu Liangji were the generals of Zhenguo, and they were transferred to the command of Suzhou Wei to guard Suzhou. ”

Zhu Yuan blinked his eyes and listened, feeling that something was wrong.

That's not right.

glanced at Hua Gao's expression, it was really wrong, this series of raps was the same, but it was obviously not a boast.

And, finally......

Zhu Yuan paused, and then asked, "What about Geng Bingwen?" ”

Hua Gao looked at it, and his expression revealed some appreciation for Zhu Yuan: "Geng Bingwen, the doctor of Zishan, the general of Zhenguo, the secretary of the Metropolitan Governor's Mansion, and the deputy envoy of the Prince's Right Command, is currently on the northern expedition to the Central Plains from the army. ”

Is the contrast so strong?

Zhu Yuan's neck was a little stiff and turned to the mighty naval fleet on the sea.

Think about the two Wu brothers again.

Wu Zhen, the deputy governor of the navy, from the second grade, may go further in the future.

Wu Liang, Suzhou Wei Commander, Zheng Sanpin.

The younger brother ran ahead of the elder brother.

After thinking about Hua Gao's previous words, Zhu Yuan could understand the problem.

Wu Liang......

It is indeed too thoughtful, so that it is a little too thoughtful, and it is so excessive that Lao Zhu begins to be afraid: you are a military general who leads troops, listens to Confucian lectures, runs schools, reduces taxes, and unites the whole body of a place to operate, what do you want to do?

Here's the problem......

Hua Gao is a bystander.

The authorities are confused, and the bystanders are clear.

BGI may have deduced the reason from the results, so I didn't think of more.

Zhu Yuan suddenly felt that he could not be regarded as a bystander like Hua Gao.

Yes...... It's a bit of a blur.

Let's take the time to think about it, think about it.
