Before going to the martial arts field, Lu Ning first went to the people in the county town and the nearby tenant farmers and farmers to walk around, this time the Zhou soldiers attacked, the people of the East China Sea were hacked to death and injured dozens of people, most of the people who were hacked to death were porters hired by a salt store, the Zhou soldiers in the city began to set fire to loot near the salt shop, it was precisely those strong laborers who were unloading, the Zhou soldiers were not merciful to these sturdy men, and several people were hacked to death in front of the salt shop.

Lu Ning went from house to house, some families lost their pillars, left orphans and widows, miserable clouds, did not expect that the lord of the country would go to comfort, and they were all flattered, and they said a lot of thanksgiving, and they were all sincerely grateful.

This made Lu Ning's heart heavy.

Tens of thousands of people in the territory, the current blessings and misfortunes, safety and danger, and all kinds of life are tied to themselves, and it is not at all what they can do if they are brave and ruthless.

There are too many things to consider, and my own life in my previous life are fundamentally two different concepts.

Walking out, looking at the reddened eyes of the big and small peaches behind him, Lu Ning said: "It seems that I have to think of a way to let these women support their families through work." ”

Women work, Lu Ning first thought of spinning workers.

My mind was tumbling over and over, pondering wildly.

……

When Aladdin was brought to the martial arts arena, Lu Ning had just finished watching the big and small peach sword dance, the two little girls were really soft, and they had practiced jiu-jitsu since they were children, and the sword dance was really good-looking, and it was really ...... Showy......

Of course, the two of them react very quickly, and their bodies are soft and can make a lot of incredible movements, and ordinary people should not be able to handle any of them with weapons one-on-one, but if there are a few military men who are holding weapons and killing indiscriminately, the two of them will definitely not be able to resist, and their strength is not strong enough.

Lu Ning was wondering if he could create some weapons that could help them increase their strength when Aladdin was brought in.

"Honorable Duke, I am grateful that you saved my life!" Aladdin bowed slightly.

Looking at this Arab businessman, Lu Ning smiled and said, "You didn't just come to thank me, right?" ”

"Lord Duke is the smartest and most mysterious person I have ever met in the world, yes, in fact, I have been thinking about it for a long time, whether to reveal Lord Duke's bounty list, because this is Lord Duke's territory, I am very worried that Lord Duke will not keep your promise after learning my knowledge. It wasn't until I saw him with my own eyes that I realized how narrow-minded I was, how could a powerful lord as ambitious and with countless whimsical ideas not keep his promises. ”

"The Duke is my savior, and I should have dedicated my knowledge to the Duke for free, but I am shouldering the mission and burden of reviving the family, and I believe that the Lord can understand it, because the Lord seems to be also carrying invisible pressure."

"The duke's bounty, I will treat it as a loan to the lord, and I will definitely return it to the lord with interest in the future!"

Aladdin's attitude is extremely sincere, and what he said is also sincere, the martial courage of the Duke of the East China Sea has exceeded his cognition, after being rescued that day, listening to the personal soldiers who came from the Duke to talk about it, the Duke of the East China Sea alone killed more than 200 swordsmen from the northern country, and he is simply not human.

Moreover, he used a longbow to slaughter the more than 100 swordsmen who kidnapped him, and he remembered vividly, and the other party was like a lamb to the slaughter, and he had no power to fight back at all.

Later, the duke's personal soldiers, took back the arrows that shot the swordsmen, Aladdin was even more surprised, the cluster of these arrows is made of fine steel, he has always felt that the Arab craftsmen are the most intelligent craftsmen in the world, although the Arabs have always been not good at inventing, but they are in the center of the intersection of East and West, so, whether it is the East or the West, the most advanced technology must pass through the Arab region, in order to spread to the distance, and the Arabs, the best is to use these new technologies and improve these new technologies.

The scimitar made by the Arab blacksmith for the children of the nobles was the best steel crafting he had ever seen, but when he saw the arrows used by the Duke of the East China Sea, his belief immediately collapsed, and the best craftsmen were also in this empire that was falling apart!

And this dukedom of the East China Sea even invented Sinan that can be used for navigation, which is also epoch-making for the history of navigation.

The Tang people are really heroes, no wonder they can dominate the world for hundreds of years!

It also made countless alien warriors gather under the banner of Datang to fight for the glory of Datang! Hate not for the Tang people!

Aladdin's heart was so excited, and for a moment he wished that he too was a citizen of this glorious empire.

At this moment, what is said is more sincere compliments.

But Lu Ning didn't like to listen to his words, and rolled his eyes, this group that has no contribution to society except for oil and beauties, what's the matter? Did you win me?

In his previous life, the Persian Gulf was a place where he often moved, and he really did not have a good impression of some Arab countries in the Persian Gulf.

"Little Hu Shang, do you know what you're talking about? All of you big cannibals, together I moved my little finger and pinched it to death, do you think you won me? Messy and emotional, do you have water in your brain? ”

If it was in a previous life, this would have involved racial discrimination, but now, it can be said openly.

The Hu businessman on the other side could only smile bitterly.

Aladdin knows the stinky problems of the citizens of this big empire, and they are the first in the world, and even dare to single out one country by themselves.

Speaking of which, they call their hometown of black-clothed food, and they have fought several wars with Datang, and Datang has not taken advantage of it, but these Tang people just look down on you, and you still think this is what it should be.

Is there any way, who calls people to have some inheritance that has never been interrupted from ancient times.

People think that they are the center of the world, all outside are barbarians, and every dynasty is replaced, but it is the big ding that represents the Central Plains and Kyushu, because the previous master was immoral, and he changed the master.

And his hometown, what god he believes in, has changed several times.

Looking at the Duke of the East China Sea with some grievances, Aladdin smiled bitterly, "Yes, the Duke is right. ”

Lu Ning looked at Aladdin, and there was a sense of pride rising in his heart, Tang was in the war with the big cannibals, and gradually lost control of the Western Regions, and on the Internet of his own era, he was arguing endlessly about who was strong and who was weak in the two empires, if he had the opportunity in the future, he would definitely turn the strength of the two empires into an iron case.

"Say, what do you think you can teach me? Looks like you're here to sell knowledge, right? Lu Ning had some expectations in his heart, are there any good things in Arabia and Persia in this era?

Aladdin was overjoyed, "Lord Duke, are you willing to buy my knowledge?" ”

"According to the rules, if I don't understand this knowledge, and the value is high, I will pay 300,000 yuan!"

Aladdin nodded, "Okay, I'm sure Lord Duke won't break his promise." ”

Lu Ning looked at him with a smile, "Then, if you can't compare to me in this knowledge, you have 300,000 yuan?" After all, you are not from my clan, I can't wait for you to raise money, and seeing that you are weak, you are not qualified to be a slave with me! ”

Aladdin froze and said, "Lord Duke, I will definitely win, and with your wisdom, you must also be interested in my learning......"

Lu Ning waved his hand, "Dry goods, don't talk about these vain heads!" ”

Although the Duke used strange words, Aladdin understood what he was saying, hesitated for a moment and said, "My merchant ships and cargo are worth more than 20,000 yuan......

This is the first time he has really owned his own merchant ships in China, but many of the goods he raised to China have been temporarily borrowed from suppliers relying on the previous reputation of his family, and the cost of the goods is equivalent to more than 10,000 yuan of Chinese coins.

Most of his goods were bartered for a large amount of porcelain and silk, and sold to Arabia, where he could reap more than double the profit, that is, under normal circumstances, he could sell more than 30,000 Chinese coins worth more than twice the profit.

Of course, it is also necessary to bear the risk of encountering pirate storms and waves, and it takes a long time to collect goods in China, in the Arab region, Tianzhu Peninsula and other places, you have to wait for the right wind direction, back and forth, it will take more than a year.

If you are lucky, you will have a great reward, but if you are unlucky, you may lose your money or even lose your life, which is the real wealth and danger.

Seeing that Lu Ning was noncommittal, Aladdin just looked at himself with a smile and gritted his teeth, "Lord Duke, have you ever heard of wolf fangs?" I bought off the chieftain there, and I owned a piece of land, which was worth 10,000 acres, and it was located in the land where ten thousand sails sailed, and one day it would become the hub of maritime trade between the East and the West! I would like to use this land as a lottery. ”

Wolftooth whiskers? Lu Ning's heart moved, the wolf's tooth whiskers that he is talking about now are the area of Peninsular Malaysia, and now in Southeast Asia, there are basically no real countries, they are all tribal forms, and the land that Aladdin said is near the Strait of Malacca.

However, the land there is not worth much now, isn't this an overdraft for the future?

"How many pirates are attached to that piece of land?" Lu Ning pursed his lips.

Aladdin was a little embarrassed, indeed, there were piles of pirates in that area.

"However, you have come all the way, I can't chill your heart, I also hope that all the people in the world will come to offer advice to this father, okay, I will give you a chance! Come, sign and draw! Lu Ning waved his hand.

Da Mi Tao sent the ready-made deed over, she was a little curious about Hu Ren, and couldn't help but look at Aladdin a few more times.

Aladdin held the deed, but was speechless.

On the deed, there are more than 20 clauses, which are much more detailed than the deeds of Arab merchants who value contracts very much.

And in duplicate.

It even stipulates that the content of the gambling between the two sides is not allowed to be talked about to the outside world.

This is also a patch that Lu Ning came up with.

Aladdin filled in the content of his color head, that is, the freedom of the goods, ships, land and the whole family, and the color head of the Duke of the East China Sea, "300,000 copper coins", was written in the brush hand.

Signing and drawing, Aladdin solemnly carried one in his arms and ordered one to be handed over to Big Peach.

"Well, Aladdin, you say, you think I don't understand, so what are you going to teach me? Let's compare this knowledge. ”

Aladdin raised his head slightly and said confidently: "The study of arithmetic!" ”

Lu Ning, who was taking the little peach teacup and drinking tea to clear his throat, almost didn't squirt out a sip of tea.

Aladdin is full of ambition, that's right, the Tang people count, there is no concept of zero, such as one hundred and eighty-one thousand and thirty-four, the Tang people will record it as one hundred and eighty-one thousand and thirty-four, such a huge addition, absolutely not as fast as he used Arabic numerals to calculate.

Arabic numerals, although not invented by the Arabs, were improved and disseminated by the Arabs, and they felt that they were the fastest way to count.

One thing to guard against is that this Donghai Gong will use the magical calculation of the Chinese.

Therefore, Aladdin is not going to use the simple addition of huge numbers as a subject, but to add several of the same number, for example, five sixteen million and two hundred and forty-one, and he has some experience in calculation, and he is going to give this addition a name.

Although the abacus is magical, the calculation of this addition is far inferior to its own small method.

"Okay, okay, who is going to come up with the problem for this arithmetic science?" Lu Ning looked at Aladdin a little helplessly.

"I'll come up with a problem, the duke will come up with a problem, two questions, let's start the calculation together!" Aladdin said, holding his head high.

He had already thought of a relatively fair method, but looking at the expression of the Duke of the East China Sea, he felt a little uneasy in his heart, and he didn't know where this uneasiness came from.

"Good, good, fair! Shall we get started? Lu Ning shook his head helplessly, feeling that it was really boring, it was too bullying.

"Good!" Aladdin is really afraid that he will have to prepare for a few days, find a few abacus masters, cheat secretly and the like, and it is best to start immediately.

The big and small peaches sent pen, ink, paper and inkstone, and the two wrote their own topics and sent them to each other.

Aladdin's title is, five hundred and one hundred thousand nine million and thirty-four add up, and you get a little.

I was secretly proud in my heart, looking at how you calculated, and seeing that the little maid with a pure and childlike and hot figure next to the Duke of the East China Sea sent the topic of the Duke of the East China Sea, she picked it up and immediately froze.

But above it is, 1,600,11,543,125 add up, how much is the number?

However, Aladdin immediately knew that the Duke of Donghai had a problem that no one could solve.

But isn't the Duke of the East China Sea self-defeating? Is there any use in giving up the opportunity to solve the problem on your own?

Aladdin's own question has already been calculated.

However, just in case, Aladdin recalculated it according to his own method.

When I was in the middle of the calculation, I was more and more proud of the calculation method that I had come up with with adding the same number.

"Alright, I'm alright!"

Aladdin is stunned!

When he looked up, he saw that the Duke of Donghai had already handed over a page of paper to his maid, and the maid came over with it.

Are you kidding?!

Aladdin frowned, took it and looked up, and immediately froze, the answer given by the Duke of Donghai was fifty-nine thousand five million and one hundred and seventy.

This number is exactly the same as the number I memorized, but I recalculated it with my own counting method, but I haven't finished it yet.

This, this!

Looking at Donghai Gong's own question, the answer he gave was, 1846.9 million.

How is this possible? This number must have been scribbled by the Duke of the East China Sea!

Or, was Donghai Gong really bored enough to calculate this number before, but how many years does it take to calculate? Decades, right?

But the Duke of Donghai gave the correct answer to his own question.

"Aladdin, do you throw in the towel?" Lu Ning asked with a smile.

Aladdin's face turned pale, but he shook his head violently, now, he can only hope that Donghai Gong's own topic is the number given randomly, and he can calculate the real number, but this, are you afraid that you will spend your whole life counting here?

Lu Ning smiled: "Okay, then you go back to the post house and count slowly, and also, you can take a look at this." He picked up a note on the side of him, and that was the process of counting the numbers.

Big Peach took it with both hands and sent it to Aladdin.

"I don't have time to accompany you for the time being, give you a month, you should be able to get some inspiration to figure it out, right? We'll talk about it then. Lu Ning smiled and said to the side: "Send him to the post house." ”

Aladdin's face was as earthy as earth, knowing that he was under house arrest, and his eyes were fixed on the papyrus of the counting process of the Duke of the East China Sea, but no matter how he looked at it, he couldn't understand it......
