As soon as Su Jing said this, everyone in the small courtyard was shocked.
Because except for Su Jing and Zhu Rui, everyone else knew that this question was exactly the question asked by Kaos.
That was a problem that they, the princes, had been pondering over and asking their teachers for help, but they couldn't solve it.
If Su Jing can figure it out, they can still understand.
But this is a bit too exaggerated to allow Lao Wu Zhu to untie half a stick of incense.
It's simply forcing someone to do something difficult.
Zhu Tong didn't know what his brother and father were thinking, so he directly picked up the paper and took a look at it, then nodded and said, "Yes, Master Su."
Zhu Rui agreed calmly.
this.
Not only Zhu Xi and the others, Zhu Yuanzhang also looked at Zhu Xi with wide eyes.
Can his own son, Lao Wu, really be solved?
Zhu Rui returned to the house, took out a pen and paper, and started calculating directly on the stone table in front of everyone.
It's just that those Arabic numerals are not understandable to Zhu Yuanzhang and others.
They could only see Zhu Ru's "ghost-drawing talisman". The half stick of incense must not have arrived, so Zhu Ru raised his head and said:
"Master Su, I have calculated that Diophantu's lifespan is eighty-four years."
For Zhu Ju, this is just an extremely simple linear equation of one variable.
It's just that when describing the topic, it is not a very direct description, and the conditions need to be extracted.
For Zhu Rui, who had experienced Su Jing's mathematics teaching, this kind of problem could only be solved by making an equation.
The difficulty of the questions that Zhu Ru usually practices is roughly the same as this.
And as Zhu Xi said the answer, Zhu Xi and others immediately looked at Zhu Yuanzhang.
This question was asked by Kaos, but they knew that their father Zhu Yuanzhang must know the answer now, otherwise he would not show it here.
All the previous shocks need to be realized at this moment when Zhu Yuanzhang's answer is revealed.
Is Zhu Xi's calmness just an act, or is he really that powerful?
The problem that had puzzled them for several days was solved by just drawing a bunch of incomprehensible symbols in front of their eyes, which took just a cup of tea.
All eyes were fixed on Zhu Yuanzhang.
Su Jing was extremely calm, while Zhu Xi was a little puzzled.
I just solved such a simple question, why is everyone like this?
He really didn't realize that not everyone accepted Su Jing's teachings like him.
"Master Su, did the student interpret it wrong?"
Zhu Ru asked Su Jing somewhat unconfidently.
Su Jing shook her head and said: "No, it's just that your father doesn't dare to believe it."
Zhu Xi turned to look at Zhu Yuanzhang and said doubtfully: "Father, this question is not very difficult. The child should not be able to do it wrong."
Zhu Yuanzhang wanted to say something to Zhu Jing, but he hesitated and did not say anything. Instead, he turned directly to Su Jing and said:
"Su Jing, have you really never seen this question before?"
He still didn't believe that this was a question asked by Kaos.
Lao Zhu could specifically ask the academic officers of the main hall and ask them to answer it carefully.
"Uncle, I'm not telling you. There really isn't much difference between a simple question like this, whether you have seen it or not. If you don't believe it, you can ask Niu Su to take a look at the questions I gave him before, and you will know."
Su Jing shrugged, feeling that things were really funny.
This question is really not difficult.
Even if you haven't learned linear equations of one variable, you can solve them just by using "Nine Chapters of Arithmetic".
Although one glance at this question, one can tell that it must have come from a foreigner, but the wisdom of our ancient Chinese people is not inferior to theirs.
At least before the Ming Dynasty, it was an absolute leading position.
Zhu Yuanzhang looked at Su Jing's expression and probably understood that Su Jing was not lying because it was completely unnecessary.
Besides, it was not Su Jing who untied it, but his son Lao Wu Zhu Ru.
He just couldn't understand it.
In fact, it was Zhu Yuanzhang's own thinking that was wrong.
The academic officials at Dabentang are all proficient in Confucianism.
This kind of arithmetic was just a low-level elementary school subject in the Ming Dynasty, and the princes did not need to study it on weekdays.
Asking them would naturally be extremely difficult to answer.
In fact, if Lao Zhu took this question and asked a few clerks at the Ministry of Finance, he would have figured it out in minutes based on the numbers and calculations they were exposed to on a daily basis.
This wave is simply because Lao Zhu went in the wrong direction.
Of course, among the previous teachers of the princes, there was another person who was proficient in arithmetic, and that was Liu Bowen.
But now, Liu Bowen is already under semi-house arrest.
All I can say is that something went wrong.
"Fifth brother, are you really good at it?"
The second eldest child, Zhu Xiang, looked at Zhu Xi as if he were looking at a monster.
"Second brother is joking. It's all thanks to Master Su's teachings."
Zhu Ru immediately replied.
The third child, Zhu Fan, looked at the problem-solving steps written by Zhu Xi and was a little confused. He asked: "Fifth brother, what do these characters mean?"
Zhu Fan immediately explained to Zhu Fan that it meant Arabic numerals and some addition, subtraction, multiplication and division.
After just a little explanation, Zhu Fan understood the meaning of these calculations.
Looking again, his eyes were full of light: "Fifth brother, I understand, that's it. It turns out that this question can be answered in this way. It's really amazing!"
His brain is easy to use and he is willing to use it.
The question itself is not complicated, and it is not difficult as long as you have the right idea.
And Zhu Fan actually figured out the answer a long time ago, but his method was just a little bit of examples.
Just make an assumption about the age of Diophantus, start from the age of sixty, and slowly verify it.
But he himself was not satisfied with this calculation method and thought that it was not solved.
But with the idea of this hypothesis, it is not that difficult to understand the linear equation of one variable.
"Third brother, Master Su taught me these."
Zhu Xi replied seriously.
Now he also realizes that the questions that seem simple to him are not simple to others.
This made him understand even more how happy it was to be able to study next to Su Jing.
The fourth child, Zhu Di, watched and listened silently, his eyes never moving away from Su Jing.
"I lost."
Zhu Yuanzhang took the initiative to admit defeat: "Su Jing, you can just ask for anything, and I can do it."
He is not a sore loser, and the emperor has no joke.
When Su Jing heard this, she just smiled and said, "Uncle, I didn't do this question. If that's the case, then you should agree to Niu Su's request."
Zhu Yuanzhang was a little surprised. He wanted to tell Su Jing that his promise was extremely precious.
This is not an opportunity that everyone can get.
It can be said that the Ming Dynasty can be achieved by anyone who can do it as long as they mention it to Zhu Yuanzhang.
But before he said anything, Zhu Rui had already said: "Master Su, this is absolutely impossible. The student's ability to solve this problem depends entirely on Master Su's teachings. The student dare not accept Father's promise."
Even though Zhu Xi is young, he is very aware of the weight of Zhu Yuanzhang's promise.
If you give it to Su Jing, it will definitely be better than yourself.
"Niu Su, what I taught you is correct, but you also learned it."
Su Jing touched Zhu Ju's head and said with a smile: "Besides, I don't lack anything, so just accept it with peace of mind."
He really doesn't care.
Zhu Rui was a little anxious now. He even wanted to tell Su Jing Zhu Yuanzhang's true identity.
"Su Jing, do you really not regret it?"
Zhu Yuanzhang looked at Su Jing at this moment.
Su Jing said: "Uncle, you are looking down on me. I know your status is extraordinary, but if I, Su Jing, want something, I will naturally fight for it on my own."
"I will not eat the food that comes to you."
Even if she didn't know Zhu Yuanzhang's true identity, Su Jing knew that this promise was precious.
But as he said, he disdained the food that came to him.
"good!"
Zhu Yuanzhang smiled and said: "Su Jing, you are well said. I like to hear this. Whatever you want, you have to fight for it yourself."
Zhu Yuanzhang, who had just conquered the world, quite recognized this point.
"Lao Wu, if you have any requests, you can tell them now."
Zhu Yuanzhang looked at Zhu Rudao again.
As soon as these words came out, Zhu Xi and others became envious.
They had tried their best to solve the problem before, just for Zhu Yuanzhang to agree to a request, but now they were directly given it by Zhu Yu, the fifth child.
But it was just envy, because Zhu Ru did it in front of them and relied on hard power.
Zhu Rui thought for a while and said, "Father, I think it's okay to keep it for now? I'll mention it later when I think of what I want."
Save.
Zhu Yuanzhang was quite surprised when he heard this answer.
But if you think about it carefully, this is the most efficient use of Zhu Yuanzhang's promise.
As long as you don't use it, it will always be there.
How should I put it, although Zhu Ru didn't learn business from Su Jing, he still learned a lot from what he heard and saw.
"Okay, I'll do as you say."
Zhu Yuanzhang nodded. Zhu Yu's performance just now made him very satisfied.
"Thank you father."
Zhu Xi immediately saluted and thanked Zhu Yuanzhang.
After losing the bet, Zhu Yuanzhang was also in trouble. He had promised Xu Da and Chang Yuchun, but how should he complete it now?
At first, I thought I could stump Su Jing, but in the end, Su Jing didn't take action personally at all.
Sure enough, even Kaos of Great Qin was far inferior to Su Jing.
Although Zhu Yuanzhang lost the bet at this time, he did not feel too disappointed.
"Uncle, why, are you still thinking about the telescope?"
Su Jing looked at Lao Zhu and smiled.
The other party did not hesitate to use this method, and they all wanted a telescope made by themselves.
Now that I can’t get it, I must still be thinking about it in my heart.
"Yes, the telescope you made is better than the boss's, but it's a pity that I lost."
Zhu Yuanzhang nodded and admitted directly.
Su Jing smiled and said: "Why do you need to go around so many detours for such a trivial matter? Just tell me no. How do you know I'm not willing to do it?"
"Um?"
Zhu Yuanzhang was stunned for a moment, then said in surprise: "What, are you willing to do it?"
Su Jing smiled and said: "What's the point? It's just a few telescopes. It only takes some time. What I don't lack most is time."
It was so simple that Zhu Yuanzhang couldn't believe it.
He looked at Su Jing doubtfully and said, "Why did you agree so readily?"
Still paranoid, this is the habitual thinking after becoming emperor.
Su Jing looked at Zhu Yuanzhang and said: "Because I can probably guess why you want the telescope. Since my things can help the soldiers on the front line of the Ming Dynasty, then I just spent some time, so what can't I do?"
"Without them protecting our home and country, I wouldn't be able to live peacefully here. We can be safe because they are carrying the burden forward."
Su Jing has always had high respect for the soldiers who protect their home and country.
It was like this in the past life, and it is like this in this life.
After listening to Su Jing's words, Zhu Yuanzhang's eyes towards Su Jing changed obviously.
Without soldiers to protect our country, there would be no stability in the rear.
These words simply spoke to Zhu Yuanzhang's heart.
To rule such a large territory as the Ming Dynasty, there were many things to consider, including internal and external troubles.
There are always people with different ideas when it comes to people's livelihood and military and political matters.
Zhu Yuanzhang has always insisted on using troops abroad, but this has also increased the burden on the country, and the burden on the country is also the burden of the people.
Now Su Jing's words hit his heart immediately.
Now the Ming Dynasty's war is to protect the country!
Without the bloody battles of the frontline soldiers, there would be no stable life for the people in the rear.
"Su Jing, what you said is very good. The soldiers on the front line are carrying a heavy burden and I would like to express my gratitude to you on their behalf."
Zhu Yuanzhang said very solemnly.
This was his sincere gratitude. In Su Jing's words, he felt the great justice of his family and country.
Deep in Lao Zhu's heart, his doubts and fears about Su Jing have also diminished a bit.
Su Jing's consciousness is high enough!
"Thank you for what?"
Queen Ma and Zhu Biao finished washing the dishes and walked towards this side with smiles.
"It's nothing, I just had a casual chat with the uncle."
Su Jing replied with a smile.
Zhu Yuanzhang also nodded.
"Mr. Su, I just heard that you were doing questions here. What's going on? It seems to be quite lively."
Queen Ma asked again.
"Mother, this is what happened."
Zhu Xi also ran out and brushed his face at this time, briefly describing the situation at that time.
Queen Ma was also quite surprised after hearing this.
"Lao Wu, it seems that you and Mr. Su have learned well."
Queen Ma looked at Zhu Rudao.
Zhu Xi immediately said: "It's all taught well by Mr. Su."
Empress Ma nodded and said to Su Jing, "Mr. Su has worked really hard to teach these two."
"Okay, okay, thanks come and go, let's chat."
Zhu Yuanzhang waved his hands and said.
No longer in the palace, Zhu Yuanzhang didn't like these superficial etiquette.
Su Jing also agreed: "Well, uncle, you are right, it would be great to chat."
He doesn't like false courtesy either. Wouldn't it be nice for everyone to get along as friends?
"Okay, I'm a woman and don't understand."
Queen Ma smiled and sat down aside.
At this time, there was a harmonious scene in the small courtyard.
Zhu Yuanzhang said: "Su Jing, look at the prosperous Ming Dynasty, what do you think of today's world?"
When it comes to chatting, it always involves yourself.
Everyone likes to boast, and Zhu Yuanzhang is no exception.
Su Jing smiled and said: "Of course he is a man of great talent and strategy. Even among the many emperors in history, he is at least among the top three."
Top three?
Hearing this, Zhu Yuanzhang's face suddenly froze.
He himself thinks that he is the first person, why is he only in the top three?
Queen Ma on the side heard Su Jing's words and asked curiously: "Then who is the number one in Mr. Su's mouth?"
