Life is nothing more than food, clothing, housing and transportation. He has enough clothes for the time being, but no food or shelter.
Li Min only had ten cents in his arms. In the early Tang Dynasty, the purchasing power of one cent was quite limited.
Some scholars believe that a fine painted porcelain plate costs about ten cents, a night in an inn costs five cents, and a day's food and lodging costs about twenty-five cents.
Therefore, Li Min's ten cents was only enough to stay in an inn for two days, and food was not included.
How can you make more money with cheats?
He instantly thought of a way.
Sell poetry!
He can instantly search for classics from various dynasties.
Write it down and you can sell it.
But where to sell it?
Outside the Imperial College! There are many nobles and rich people there.
Only in this way can you maximize your profits without fear of running out of sales!
Selling poetry requires pen, ink and paper. Paper is too expensive and he can't afford it, but pen and ink is fine. As for paper, he has to find another way.
So, he headed towards the place where the calligraphy books were sold.
He didn't know that as soon as he left, hundreds of people gathered around a middle-aged man and came towards the bookstore. It was very lively.
After they entered the library.
The man saluted everyone.
"Everyone is so kind to you, and I, Li Chunfeng, can't thank you enough. It is Your Majesty's hope that you can teach some good young talents! You must study hard!"
It turned out that this person was Li Chunfeng, who was born with a Taoist spirit and was full of energy.
He sat above the podium, and the previous screen had been removed.
There were a lot of people sitting down there.
"Zhenren Li serves the people and the country, which is admirable!"
The speaker is the master of the bookstore, his name is Chen Hong!
Li Chunfeng said: "Where is it? Why don't we start now?"
Everyone said yes and became quiet.
Li Chunfeng was treated like a star, which made him smile.
Facing hundreds of students below, he opened the nine-chapter volume on arithmetic.
I didn't know this, and I was shocked when I saw it.
His eyes did not move, and he kept staring at the letter.
And the more I looked at it, the more shocked I became.
He muttered: "Who did this...?"
Everyone was confused, and Chen Hong seemed to have noticed something was wrong.
So he stepped forward and asked, "Zhenren Li, what's wrong? Isn't this nine-chapter book on arithmetic wrong? How about I ask someone to change it?"
Then I saw the handwriting on the slip.
Write the entire letter to the letter.
I couldn't help but get furious.
"Who did it? Who wrote on the slip? Who was it?"
As soon as these words came out, everyone panicked.
After all, they were the ones who sorted it out just now, and no one can get away with it.
And these are the only children who can enter the school.
You may not be able to pinpoint which child is responsible for the prank.
When Chen Hong was about to get angry.
Li Chunfeng said:
"A genius, a real genius! He can solve all the answers to all the questions, and also provides such a novel way to solve the problems. I, Mr. Li, have lived in vain for so long, but I don't know that there is such a method in this world.
Explanation! It really makes me ashamed!”
This statement made everyone confused.
what happened?
Could it be that someone touched the slip and solved the problem on it?
So Li Chunfeng was surprised.
What kind of genius is that!
Then, he said: "Chen Hong, are you teasing me on purpose? Are you trying to embarrass me on purpose?"
These words frightened Chen Hong and said quickly: "Zhenren Li, how dare we?"
"Then how do you explain this?"
"I don't know about this either. I don't know who wrote the answer on it. I can swear to God, this is not our fault!"
His expression was sincere and he didn't look like a liar at all.
So, it's not intentional.
When Li Chunfeng heard this, his eyes were full of fire.
"Whoever can answer this must be a genius! You must find out who did it! I will go to see your Majesty right away!"
Li Chunfeng said excitedly.
All the students below were confused.
What about today's class?
Didn’t you agree to teach everyone nine chapters of arithmetic?
Why does this happen?
Chen Hongze stepped forward and said: "Zhenren Li, this student is still here. How about finishing the class first and then leaving?"
Everyone was looking at him, hoping that he would finish his lecture before leaving.
However, he said:
"No, it's not a trivial matter at this time. We must meet His Majesty, and we cannot lose such a talented person. I'm sorry, but as for the lesson, I'll teach it another day. Farewell!"
After finishing, Li Chunfeng took the slips and walked out of the bookstore, leaving hundreds of people there in a daze.
"Hey, who is this? Why do you give the answer at this time?"
Chen Hong sighed.
And Li Chunfeng went directly to Tai Chi Palace.
He felt windy while walking and was very eager to tell Li Shimin the news.
Li Shimin is still depressed because of what happened to Li Min yesterday.
When I saw Li Chunfeng in such a panic, I couldn't help but become nervous.
Could it be that something happened?
You know, Li Chunfeng is an astronomer, and he has to rely on him to observe some celestial phenomena.
Once there is any bad sign, he will definitely come to him as soon as possible.
Could it be...
"I pay my respects to Your Majesty!"
"Why is my dear so flustered?"
"Your Majesty, all the arithmetic problems in the nine chapters have been solved."
"Hasn't the question of the arithmetic in Chapter Nine been solved a long time ago? What's the point of panic?"
"Your Majesty, I was wrong. The algorithm of Jiu Zhang's arithmetic has been improved. It only takes three or four steps to completely solve the problem!"
Regarding clear calculation, that is very important.
Because it is very important. It will be used in marching and fighting, as well as astrology. The key point is that it is even more important for the development of science and technology.
That's why it was treated as a separate subject in the Imperial Examinations of the Tang Dynasty.
"What did you say?"
Li Shimin was very surprised.
He has also learned arithmetic, and knows that the solution to a Jiujian arithmetic problem cannot be written on two feet of cloth. Sometimes it even takes ten feet of cloth to write down the solution.
"Your Majesty, please look!"
Li Chunfeng was so excited that he handed over the letter.
The eunuch on the side quickly put away the things and handed them to Li Shimin to see.
After Li Shimin saw it, his whole body was frozen there.
"This...what text is this?"
"Your Majesty, this is the text of Dashi. As far as I know, it was introduced to the Central Plains as early as the Three Kingdoms period."
The so-called Dashi is the ancient name of Arab countries.
Arabic numerals were invented early and were introduced to the Central Plains relatively early, but they did not develop.
Li Chunfeng actually understands these numbers, which can be said to be a very in-depth study.
"Can you understand the relationship?"
Li Chunfeng behaved a little unnaturally.
"I still know a little about some symbols, but this person can turn the complex into simplicity. This level of achievement requires thirty years of work! If this person can be found, it will definitely bring the Tang Dynasty's calculations to a higher level. The power of the Tang Dynasty will be greatly improved."
It will speed up even more."
If he knew that the other person was just a teenager, his expression would be very interesting.
"This handwriting..."
Li Shimin seemed to notice that the handwriting was somewhat familiar.
Li Chunfeng said again: "This person's handwriting is vigorous and vigorous, and it must have been ten years of skill."
"You don't have to look for it, I know who this person is!"
Li Shimin said firmly.
Li Chunfeng was a little shocked when he heard this.
"Your Majesty, do you really know who it is?"
"This is Min'er's handwriting!"
He taught Li Min his handwriting. Some of the boy's handwritings were very distinctive, and he could tell them at a glance.
What?
"What do you mean, Your Majesty?"
"This handwriting is that of my sixth son, Li Min!"
How could this be?
"Then can you please ask the Sixth Prince to come out and clear up the confusion?"
Li Chunfeng was overjoyed.
If you want Li Min to come out, it will be good for the future of Datang!
"Don't mention this matter! Go down and study his solution. As for finding him, let's talk about it later!"
Why? Can't you just ask directly? Why go in such a big circle? Obviously, he doesn't know what happened last night.
"Your Majesty, why?"
"Don't ask why, just do your research!"
Seeing that Li Shimin seemed angry, Li Chunfeng did not dare to ask any more questions.
The only answer is "Yes!"
Li Shimin's expression became very strange.
As soon as Li Min was kicked out, he did such a shocking thing.
Is everything as he said?
Shouldn't he marry Princess Changle?
Puzzled, unclear, unable to understand.
"You go down!"
"yes!"
Li Chunfeng withdrew with doubts. He thought in his heart that he must find the Sixth Prince to help him solve his doubts. No matter what, he had to find a method, even if he wanted to be his teacher.
As for Li Shimin, he remembered what Li Min said when he left.
Then he shouted:
"Come here, quickly send people to Shandong and Henan to check the river channels. If there is any situation, report it immediately!"
