"Mom, dad is so ill, why didn't you inform me earlier?" Lin Xuan couldn't help complaining as he saw Lin Dongyang lying on the bed with a pale face and no sound.
Zhang Qing said angrily: "I originally wanted to inform you, but your father heard that you were entertaining guests and refused to let you know."
Lin Xuan knew that Zhang Qing could not be blamed, and asked: "Mom, dad was fine when we had dinner last night. Why is he suddenly so sick?"
Before a person gets sick, there must be some warning signs. A person who was alive and kicking yesterday suddenly becomes like this without any warning signs.
"I just caught a cold, there's nothing to worry about." Lin Dongyang said weakly.
"At this time, I still want to be tough." Zhang Qing glared at Lin Dongyang and said: "When your father was eating last night, he heard you say that the vegetables grown in the greenhouse had grown, and he was curious.
I wanted to go take a look, and I stayed in the greenhouse for more than an hour before I came back. I woke up like this this morning."
Lin Xuan seemed to know the reason. The greenhouse had begun to heat up. Lin Dongyang must have been sweating after staying in it for so long. In addition, the temperature difference between day and night is huge. It would be strange not to get sick when he comes out and is blown by the cold wind.
"Mom, I have sent someone to ask for Dr. Sun, don't worry." Lin Xuan said.
After Sun Simiao arrived, the examination results were indeed what Lin Xuan thought, that he had suffered from wind and cold.
"Don't worry, it's nothing serious. I'll prescribe you some medicine and you'll be fine after taking it for two days." Sun Simiao said.
After receiving Sun Simiao's prescription, Zhang Qing ordered someone to get the medicine and thanked Sun Simiao: "Thank you, Doctor Sun."
"This is what I should do, no need to thank you." Sun Simiao waved his hand.
"Mom, you take care of dad, and I'll go and see Doctor Sun off," Lin Xuan said.
When he left Sun Simiao behind, he thought he could use it in case someone in his family got sick.
"Director, the hospital is almost completed and will be put into use next year," Lin Xuan said.
"Master Hou has taken the trouble." Sun Simiao said.
Lin Xuan smiled and said: "The royal family should have many books on medical skills. When the time comes, I will ask your majesty to get them, print a copy and leave it in the hospital."
"Is what the Marquis said true?" Sun Simiao looked at Lin Xuan in surprise.
The royal family had many precious books on medical skills, and he had read some of them back then.
Li Shimin also used those books to seduce him and stay in the Imperial Hospital.
Although Sun Simiao finally refused, it did not mean that he did not like those books.
Those classics were of great help to him in writing medical books.
"Of course it's true." Lin Xuan nodded.
In less than ten years after the invention of woodblock printing, the Four Books and Five Classics could not be printed, so there was no way to print any medical books.
Most of the medical books handed down today are bamboo slips and manuscripts, and many of them are unique.
Even though Lin Xuan gave him very good treatment, he still had no place to buy medical books if he had money.
"Thank you, Lord Marquis." Sun Simiao thanked him.
"Taoist Master, you're so polite. I'm sorry to trouble you, Taoist Priest, but I haven't even thanked him yet." Lin Xuan said with a smile.
For people like Sun Simiao, money and other things are not important at all.
Only by giving in to what he likes can he be conquered. The reason why Li Shimin failed was because he didn't know what Sun Simiao wanted.
Lin Dongyang took medicine and slept, and felt much better at night.
The next day, Lin Xuan went to check and found that Lin Dongyang was already 70% or 80% better.
Lin Xuan felt relieved and headed to the academy.
However, when he came to the academy, Lin Xuan met someone he didn't expect.
"Master Li, why are you here?" Lin Xuan asked in surprise.
Li Chunfeng smiled and said: "I have met Mr. Hou. I heard that Mr. Hou invented a kind of Arabic numerals. I want to learn about it."
Li Chunfeng was very obsessed with arithmetic. Arabic numerals were easy to write and calculations were very convenient.
"Since Master Li is so interested, would you be interested in teaching at Boyuan Academy?" Lin Xuan asked.
Li Chunfeng has a doctorate in arithmetic from the Imperial College. If Li Chunfeng can teach at Boyuan Academy, it will not only make up for Boyuan Academy's deficiencies in arithmetic, but also make up for the academy's deficiencies in heritage.
Although there are many teachers in the academy, these teachers are not very famous.
After all, Boyuan Academy is a newly built academy, so it is very difficult to attract famous teachers.
Li Chunfeng said with some embarrassment: "Master Hou, I'm busy with things, I'm afraid I don't have time."
He has an official position and has to teach at the Imperial College, so he has no spare time to teach at Boyuan Academy.
Lin Xuan smiled and said: "How about we make a bet?"
"Bet?" Li Chunfeng frowned slightly, he didn't like gambling.
"I'll give you a math question, and if Mr. Li can't answer it, how about you agree to teach at Boyuan Academy?" Lin Xuan said.
Li Chunfeng said: "Master Hou should know that some arithmetic problems cannot be solved in a short while."
Arithmetic is his strongest field, so naturally he cannot admit defeat.
But there are many arithmetic problems, and the calculations take a lot of time. If Lin Xuan had time constraints, he would not be able to do it.
What's more, there are many problems that have been circulated for hundreds of years and no one has calculated the results. If Lin Xuan gave him such a problem, he would not be able to solve it no matter how much time he had.
Lin Xuan seemed to know Li Chunfeng's worries and said with a smile: "Don't worry, the question I asked is definitely not a perfect question. This question is very simple, so I can't give you too much time, I can only give you one hour to calculate."
"If it's true as you said, I'll make a bet with you." Li Chunfeng said.
Lin Xuan said it was not a difficult topic and it was very simple, so he naturally had no reason to refuse.
As a highly praised mathematician, Li Chunfeng naturally has his pride.
"Three people went to stay in an inn together, each paying ten cents. That day happened to be one year since the inn opened. To celebrate, the innkeeper decided that guests staying that day could enjoy a discount. The innkeeper asked the waiter to refund five cents to the three of them.
Er Jiancai revolted and took two coins, but returned three coins. In this way, the room fee for each person staying in the inn was nine coins, and the total for the three of them was twenty-seven coins. Including the two coins hidden by the waiter, the total was
It’s twenty-nine cents, where is the other cent?” Lin Xuan said.
Lin Xuan had racked his brains to solve this problem in his previous life.
In fact, it is not difficult, I was just misled by the title.
The three of them spent thirty cents, and the shopkeeper asked him to withdraw five cents, which was twenty-five cents. Plus the three cents returned and the waiter's two secret treasures, a total of thirty cents.
But when everyone heard the title, they were misled by twenty-seven plus two.
Li Chunfeng frowned deeply after hearing this.
This question is indeed not difficult and has never appeared before, but after careful calculation, he could not find any clue.
Not only Li Chunfeng, but also Xu Geng and others were scratching their heads.
Although they are not majoring in arithmetic, ordinary questions are not difficult for them.
Lin Xuan smiled to himself when he saw their appearance.
Li Chunfeng can be regarded as one of the best mathematicians of this period, but the ancients had never seen so many routines. He calculated exactly according to the ideas given by Lin Xuan.
Each person has ten pennies, minus one pennie, and nine pennies are left, which is thirty-nine twenty-seven. Adding two pennies is indeed only twenty-nine pennies. Where did the remaining one penny go?
The more Li Chunfeng thought about it, the deeper his frown deepened.
Half an hour passed in the blink of an eye, but Li Chunfeng had no clue.
