Nearest the king nearest the gallows.

Li Zhong is deeply aware of this.

Especially during this time, Li Shimin has become more difficult to serve.

"Your Majesty, the Hundred Cavalry Division has just received news that His Royal Highness the King of Chu has accepted a disciple today."

Apprenticeship was a very important thing in ancient times.

In the same way, it is also true to accept disciples, especially for princes like Li Kuan.

"Huh? Isn't it the first birthday banquet of the county lord of Yongping today? Why did Li Kuan put away his disciples? ”

Li Shimin was really interested in this news.

"No one really knows why His Royal Highness the King of Chu suddenly rose up to accept disciples. However, that person is Di Renjie, the grandson of Shangshu Zuo Cheng Di Xiaoxu, and I heard that he is quite famous. ”

Li Zhong has long learned to be obedient, and he tries to do as much homework as possible when he comes to report.

"Di Xiaoxu?" Li Shimin thought for a while, "I am a little impressed. Speaking of which, Taiyuan Di's is also well-known in the local area. ”

Li Shimin and Li Zhong briefly learned about what happened in the Chu Palace, and then continued to be busy reviewing the folds.

……

Di Renjie's day was very extraordinary.

As a precocious man, he has a certain understanding of how much influence he has on his apprenticeship.

To put it mildly, for myself and for the Di family, this is an important symbol.

Therefore, early the next morning, he took the packed books and clothes and came to the courtyard of the Chu Palace.

However, Li Kuan hasn't gotten up yet.

The subordinates in the palace also knew his identity, but they didn't let him eat a closed door.

However, without Li Kuan's instructions, everyone didn't know how to arrange him, so they brought tea and asked him to wait in the lobby first.

When he came to the palace of the king of Chu for the first time yesterday, Di Renjie didn't pay much attention to the scenery and buildings in the palace.

At that time, all of his thoughts were in books, and he thought that Ah Weng was wasting his life by bringing himself to this kind of banquet.

Now, stepping into the palace again, his state of mind is different.

"Xiao Langjun, please drink tea."

Soon, a maid served tea to Di Renjie.

The tea leaves in his master's house are notoriously good, Di Renjie sat down to taste tea very comfortably, quietly waiting for his master to call him.

However, he hadn't waited for Li Kuan yet, Liu Yuan and Li Yan came first.

"Brother Liu, look, there's nothing wrong with listening to me."

Seeing that Di Renjie was already waiting in the lobby, Li Yan smiled and said to Liu Yuan.

Liu Yuan stared at Di Renjie in the hall, wanting to discover his extraordinary.

Not tall or short, not fat or thin, not handsome or ugly, very ordinary.

Why did Master take the initiative to take him as an apprentice?

Di Zai is not a big family in Bingzhou, and there is no need for the master to win over.

Could it be that there is something special about him that he doesn't know?

By the way, I heard that he was watching "Advanced Arithmetic" at the banquet yesterday, did he accept him as an apprentice just because of this master?

No, I have to check for Master, in case he was pretending at the time, Master's reputation for the first time could not be ruined in his hands.

Liu Yuan thought as he walked into the lobby.

Di Renjie naturally saw the two people who came in, but he was still a guest now, and he didn't know whether the other party was a person from the palace or other guests, so after showing a smile that met social expectations, he didn't speak.

"You are Di Renjie, the newly recruited disciple of His Royal Highness the King of Chu?"

Li Yan spoke first, and he really looked like the emperor was not in a hurry and the eunuch was in a hurry.

"I'm Di Renjie, may I ask who the two are......"

Di Renjie has just arrived, and he can't figure out the situation.

Although he has always been arrogant, but today he saw Li Yan, who was also a little arrogant, but he was not angry.

"I'm Li Yan, a student of Guanshishan Academy, it doesn't matter if you remember it or not. But the one next to me, you must remember, that is your senior brother. ”

"Senior Brother Liu?"

Di Renjie tried to call at Liu Yuan.

After leaving the annex of the Chu Wangfu yesterday, Di Renjie was also urgently instilled with a lot of things about the Chu Wangfu.

As Liu Yuan, Li Kuan's only disciple, he naturally heard of it.

"Hmm."

Liu Yuan replied with a complicated expression.

If you want to compare Di Renjie, the master must have no opinion.

But if he is rude to the little junior brother there for no reason, he may make the master unhappy.

"I heard you're proficient in arithmetic?"

Li Yan saw that Liu Yuan was still standing there and did not speak, so he simply took the initiative to control the rhythm of the conversation at the scene.

"I know a little bit about it, and I don't dare to say that I am proficient."

In Di Renjie's view, Li Yan is a student of Guanshishan Academy, and Liu Yuan is a senior brother, and they should be extraordinary in the way of arithmetic.

Especially Liu Yuan, he knew that this senior brother had won the top prize in the Ming Arithmetic Department.

Therefore, Di Renjie, who has always been very conceited, is also rarely humble.

However, Li Yan obviously did not intend to let him go.

"That's it, anyway, His Royal Highness the King of Chu is not available yet, why don't you let me test your arithmetic level first? Anyway, you will definitely go to Guanshishan Academy to study later. ”

"Yes!"

Di Renjie looked at Li Yan, looked at Liu Yuan, probably tasted something, and agreed directly.

"That's it, I heard that you're already learning "Advanced Arithmetic", so I'll simply come up with two questions first to see if you can do it."

Li Yan didn't think about making it difficult for Di Renjie, but he was just going to take out some of the daily topics of the academy.

If Di Renjie can answer at such an age, it can be regarded as worthy of His Royal Highness the King of Chu to accept him as an apprentice.

"No problem, I also have a few questions, and I want to ask Senior Brother and Senior Brother Li together."

Di Renjie showed a sly smile on his face.

"Listen, I'm going to have a question."

Li Yan didn't think about it for too long, so he chose a few questions from the questions he had done.

"There was a square city, and we didn't know how big it was. The four directions of the city are opened from the middle of the city wall, there is a tree twenty steps out of the north gate, fourteen steps out of the south gate, and you can see the tree in 1,775 steps to the west. ”

Li Yan spent a quarter of an hour to make this question, and according to his understanding, if Di Renjie could be faster than himself, it would be considered a few brushes.

After listening to Li Yan's title, Di Renjie didn't ask the maid next to him for pen, ink, paper and inkstone, and directly dipped his fingers in the tea and wrote quickly on the table.

It was just a cup of tea, and a smile appeared on his face, "Two hundred and five!" ”

Li Yan was stunned when he heard it, this speed is faster than himself, it seems that at least "Advanced Arithmetic", Di Renjie has really learned it, and he was not pretending yesterday.

Compared with Li Yan's reaction, Liu Yuan's face looked a little strange.

This Brother Li, what question is not good, but the answer to one question is two hundred and five.

Others don't know, as a disciple of His Royal Highness the King of Chu, can they still not know that this "two hundred and five" is one of the mantras of the prince?

That's a curse!

Looking at Di Renjie saying "two hundred and five" to Li Yan, Liu Yuan felt that he should go into battle by himself next.

……

The greenery of the courtyard of the Chu Wangfu is very good, except for the occasional birdsong and cicada chirping, the lobby falls into a brief silence. Li Yan felt that Liu Yuan's level was higher than his own, and it was understandable, after all, he was the champion of the Ming Arithmetic Department.

But what's going on with this Di Renjie?

A child of the age of 仈 Jiǔ answered the question that he thought was still a little difficult so lightly.

At least for those who have not studied modern arithmetic, it is a difficult question.

"Little junior brother, senior brother, I will also test you with a few questions, if you can, in the future in the Guanshi Mountain Academy, senior brother will cover you."

Liu Yuan looked at Di Renjie with a smile, and he didn't have too many bad intentions in his heart, just curiosity and a trace of unconvinced.

"Senior brother, please ask the question!"

Di Renjie continued to show a smile that met the expectations of society.

This kind of expression, from childhood to adulthood, he has used it a lot, but he doesn't have to deliberately force himself.

"Today, there is a road around the mountain that is 325 miles long in a circumference, and three people in A, B, and C walk around the mountain, and we now know that they can walk 150 miles, 120 miles, and 90 miles respectively every day. Assuming the walk is uninterrupted, ask how many days from the same .asxs. will we meet again at the departure point?

After Di Renjie listened, he silently recited the question, and then compared it on the table with the same reaction just now.

This time, the kung fu of a cup of tea has passed, and Di Renjie has not yet answered.

Li Yan, who was watching the excitement from the sidelines, breathed a sigh of relief, feeling that this guy was finally not so rebellious.

"Ten days and ten hours later, they will meet at the starting point."

Before Li Yan was funny, Di Renjie's voice broke Li Yan's fantasy.

"Is that right?"

Li Yan looked at Liu Yuan with a curious expression.

Although Li Yan has done similar questions, he has never done the exact same.

Therefore, whether Di Renjie's answer is right or not, Liu Yuan needs to confirm.

"Exactly!"

Liu Yuan looked at Di Renjie and Li Yan with a complicated expression.

Similar topics are taught in the Arithmetic College of Guanshishan Academy, but the exact same topic, Liu Yuan is sure that absolutely no one has ever done it.

Because this is the number I just came up with last night.

Now that Di Renjie has calculated correctly in such a short period of time, it either means that he has studied new arithmetic in depth, or it shows that he ......

Liu Yuan prefers to believe that it is the former case.

"Come again, listen to ......"

Liu Yuan took out another question that he had prepared, and the difficulty was even higher than the one just now.

It's a pity that it's just a cup of tea for a while, and the accurate answer came out of Di Renjie's mouth.

At this time, whether it was Liu Yuan or Li Yan, they all began to face Di Renjie.

No matter how His Royal Highness the King of Chu made his judgment yesterday, he wanted to accept him as a disciple.

However, at least judging from the current situation, Di Renjie's arithmetic level is definitely first-class.

In time, it is entirely possible to win another champion of the Ming Arithmetic Department for Guanshishan Academy again.

"Hear the question clearly......

"Senior brother, it's thirty-four, right?"

"Come ...... again"

"Twenty-two!"

Liu Yuan came up with several questions one after another, but none of them stumped Di Renjie.

At this time, Di Renjie said with a smile: "Senior brother, I also have a few questions I want to ask, is it okay?" ”

Looking at that innocent look, Liu Yuan had no way to say no.

Of course, he also had a faint expectation in his heart to see if he could answer Di Renjie's question in a shorter time and find some face to come back.

Everyone knows very well that it is said to be asking for advice, but in fact, this is a mutual test.

Don't you think you need to check my level and see if I'm qualified to be your junior brother?

Then I also have a temper.

I'm going to have a few questions to see if you, the senior brother, are really qualified?

"Six people of different heights are arranged in two horizontal rows and three columns, and each person in the first row is shorter than the person behind him in the same row, so how many are the different types of arrangement?"

As soon as Di Renjie's question was finished, the expressions on Liu Yuan and Li Yan's faces were relaxed.

I thought he would find a few difficult arithmetic questions from some ancient books to test himself, but I didn't expect it to sound so simple.

Liu Yuan also did the same, did not ask the maid for pen, ink, paper and inkstone, came to the table and began to compare.

"Six people, in two horizontal rows and three columns."

Liu Yuan had words in his mouth, thinking in his mind which formula he had learned could be applied to this question.

A quadratic equation?

Binary quadratic equations?

It seems a little bit wrong.

Liu Yuan's fingers were gesturing on the table out of thin air, but he didn't think of it for a long time.

Seeing that the kung fu of a cup of tea was about to pass, Liu Yuan found that all the formulas he had learned did not seem to be applicable to this question.

Although the weather had turned cooler, fine sweat began to emerge from Liu Yuan's forehead.

"Get me some pen and paper."

Liu Yuan is also a frequent visitor to the Chu Palace, although he can't call the name of the maid next to him for a while, they all know each other.

Now is not the time to do the big thing, and it's better to answer it after making a draft than not being able to answer it, right?

Li Yan also had a solemn face on the side.

Although today's protagonist is not himself, if the questions made by the two of them were easily answered by Di Renjie.

On the contrary, Di Renjie "asked" a question, which stumped the two of them.

Then in the future, they don't want to raise their heads in front of Di Renjie and be people.

Could it be that His Royal Highness the King of Chu has a special sense of knowing people?

I've never heard of Di Renjie before.

Looking at yesterday's scene, the prince should have seen him for the first time.

Why is it so easy for the prince to find out an arithmetic genius?

Before Li Yan could think too much, a maid came to the hall with a quill pen and white paper.

Liu Yuan and Li Yan were no longer polite, they each picked up a pen and paper and began to think about how to answer this question.

However, there are some problems that you can't find a solution to if you work hard enough.

After another cup of tea, Liu Yuan already had beads of sweat the size of beans on his forehead.

No matter what, I'll confirm them one by one.

Liu Yuan was ruthless in his heart and was ready to use the most primitive method to answer this question.

Although he vaguely felt that there should be a special method to solve this question quickly, he couldn't think of anything he couldn't think of.

Instead of freezing there, it is better to use a stupid method and pass this level first.

Suddenly, the lobby fell silent again, except for the faint "whoosh" of a quill pen scratching across the paper.

"Ninety, ninety, right?"

After estimating that after half an hour, Liu Yuan finally breathed a sigh of relief and said his answer.

Luckily, there were only six people in line, if there were sixteen, or more......

Then I just don't eat or drink today, and don't even think about answering it.

"Congratulations, senior brother, you answered correctly."

Di Renjie saw Liu Yuan, who breathed a sigh of relief, and a smile appeared on his face.

This senior brother also looks mediocre.

"I have another question for a teacher?"

Before Liu Yuan could wipe the sweat off his forehead, he heard a demonic voice again.

Liu Yuan had never thought so much about Li Kuan, and he hurriedly appeared in front of him. It wasn't that he didn't wait for Li Kuan to get up in the lobby before.

But to wait as hard as today, that has never been experienced before.

Hearing Di Renjie's voice, Liu Yuan wanted to refuse very much, but thinking that he had tested several questions just now, Di Renjie did not refuse.

If you only answer one of them, you won't even have the courage to answer further......

If this spreads, how can I mix in the Guanshishan Academy in the future?

"That'...... That...... Little junior brother, just ask. Anyway, the master hasn't come over yet. ”

Liu Yuan put on a smile that was even uglier than crying.

At this moment, Li Yan was already sitting silently in a corner, picking up a teacup and drinking tea.

You can't see me, you can't see me.

The left and right are just their brothers fighting the law, what are they involved in?

Li Yan regretted a little that he came over with Liu Yuan today to watch the excitement.

Where is this to see the excitement?

It's like baking yourself in the oven.

"I have a box with six pairs of gloves of different colors, and I can take four of them, and how many ways can I take them in exactly one pair of the same color?"

Di Renjie's face showed a smile again, but this smile was the same as a demon in Liu Yuan's eyes.

Don't think about it, just listening to the topic, Liu Yuan felt a pain in his brain.

This is obviously the same type of question as the previous one, but it seems to be more difficult.

I haven't found the skills to solve the problem, and I only rely on hard spelling one by one to figure out the answer, and the process is ......

As long as one mind wanders, you have to start all over again.

However, at this moment, there is no point in saying more.

Liu Yuan took a deep breath, ready to answer this question first, and then talk about it after passing this level.

As for the problem-solving skills of this kind of problem, let's go back and study it yourself.

It seems that there is no hole in this, if you can really find out the law from it, maybe you can find a different path in arithmetic.

If this is the case, my grievances today will not be in vain.

Liu Yuan expelled the distracting thoughts in his heart and began to use the most stupid method to solve this question.

This guy wants to think of himself as a computer, listing the answers one by one, and coming to the final result.

In the lobby, there was a moment of silence.

After tossing for half a morning, naturally someone told Li Kuan about the situation here.

However, after Li Kuan knew about this situation, he simply decided not to go first, let them have a good competition, and it can be regarded as completing the preliminary examination for himself.

Seeing that the sun was rising, Di Renjie felt that his stomach was growling with hunger, and Liu Yuan finally stopped his busy hands.

I saw him stare at the draft full of drafts on the table, and he breathed a sigh of relief when he was sure that his answer was okay.

"Two hundred and forty, junior brother, the correct answer is that there are two hundred and forty methods, right?"

Liu Yuan's eyes were fixed on Di Renjie, for fear of hearing a negative answer from his mouth.

Even Li Yan, who was pretending to be an invisible person in the corner, came over nervously.

"Congratulations, big brother, it's absolutely correct!"

Although Liu Yuan's method is very earthy, he can correctly answer the answer, which can be regarded as proving his arithmetic level to a certain extent.

If it were a different person, and confirm it between the two hundred and forty methods, it would have been dizzy a long time ago, and it would not be so easy to calculate at all.

The hard trip also has the strength of the hard trip.

"Whew!"

Liu Yuan sat down on the chair with his whole body, his hands constantly wiping the sweat on his forehead.

At this time, he felt that his feet were numb, and his whole body was soft.

"Senior brother, I still have a question ......"

"Little junior brother, it's not early today, let's come back another day."

Without waiting for Di Renjie to finish speaking, Liu Yuan hurriedly spoke out to stop him.

The first question is ninety, and the second question is two hundred and forty, which is more than a thousand......

Then you can't die of exhaustion here today?

"yes, that's all for today. His Royal Highness the King of Chu should have also gotten up, so let's ask someone to go over and ask. ”

Li Yan also hurriedly interjected a sentence on the side.

I catch eagles every day, but today I was accidentally pecked by an eagle.

It seems that what His Royal Highness the King of Chu said is really reasonable, the way of arithmetic is broad and profound, and there are still many places where everyone needs to work hard.

"Okay, then I'll ask Senior Brother for advice another day."

Di Renjie also breathed a sigh of relief in his heart.

He had already guessed that he would worship His Royal Highness the King of Chu, and there would definitely be some twists and turns.

Now, I have finally passed the level of senior brother.

At least in arithmetic, no one should dare to question themselves, right?

"Lord Wang!"

"I've seen Master!"

"The disciple has seen the master!"

In the movie, the police always show up after the dust has settled.

When Li Kuan came to the lobby, Liu Yuan and Di Renjie were already chatting about Guanshishan Academy there.

"Huaili, what are you talking about with your senior brother, so happy."

Li Kuan didn't want to give Di Renjie any intention of getting off the horse.

Of course, if others want to test his quality, Li Kuan will not object.

"Master, the senior brother is teaching some of the content in the academy, and the disciple is also curious."

Although Li Kuan asked Di Renjie to move to his house to live for a while, he definitely couldn't teach him in person every day.

More often, Di Renjie still has to go to Guanshishan Academy to study by himself.

Of the six academies, Li Kuan didn't plan to let Di Renjie specialize in any one.

It's best to be able to cover every single one.

For Liu Yuan, Li Kuan only hopes that he can be satisfied with some achievements in arithmetic.

However, for Di Renjie, Li Kuan's requirements are high.

To be a qualified prime minister, it is not enough to just learn arithmetic well, and it is even more difficult to only understand the scriptures.

After two years, Li Kuan was even ready to let Di Renjie get in touch with the commerce of the Chu Palace, so that he could learn about the various workshops and the operation of the giants such as the fishing industry in the East China Sea and the Northwest Trade.

Only by understanding this, what will be said in the court and the decisions made in the future will not be a mess of patting the head.

"It just so happens that you are all here today, and I will arrange Huaili's study plan for the next few months."

Entry-level things, Li Kuan is not going to teach them personally, and after Di Renjie has learned all the things of the nine-year compulsory education, it is time to really play his role.

"Huaili, starting tomorrow, you will first read in the library of the palace in the morning, and then go to Guanshishan Academy to listen to lectures in the afternoon. If there is anything you don't understand, you can ask your senior brother first, or you can ask Li Yan. ”

As soon as Li Kuan's words were finished, Liu Yuan and Li Yan looked embarrassed.

The two of them were abused by this little junior brother just now.

When the time comes, it's really hard to say who will teach whom.

"Disciple obeys!"

Di Renjie agreed very modestly.

After that, Li Kuan simply arranged some things and sent them away first.

Then he turned around and went to play with Little Corn.
