An examination room on the east side of the campus of Jinling University.

found an opportunity to come forward to meet the former Yinghai envoy, the current Zhongshu Pingzhang and the royal family, and when Zhu Yuan left, Chang Ying immediately felt that the expressions of many scholars around him were obviously different.

Except for a few who were cold and even disdainful, most of them showed a bit of eagerness and took the initiative to talk. And the few I knew before are now a little more enthusiastic.

From the middle book of a product!

Thinking of this, Chang Ying couldn't help but sigh while socializing.

A fourteen-year-old young man has reached a height that many people can hardly reach in a lifetime in less than a year.

As for the status of a royal family who may inherit the title of county king, it is even more rare to inherit from the side branches, and moreover, he still enters the royal family.

At this time, he "encountered" Zhu Yuan, of course, Chang Ying didn't want to temporarily pull the relationship and let Master Pingzhang open the back door for him, he knew that Zhu Yuan was not such a person.

It's a simple idea: show your identity and make friends in the same year.

Chang Ying doesn't think there's anything wrong with doing this, and she doesn't worry about what will happen if Lord Pingzhang knows, according to his father's words and what he saw with his own eyes, Pingzhang has always been a very mellow person.

Pulling the tiger skin for a short time, not only the surrounding scholars, but even a Guozijian official who was in charge of the invigilation here talked to him a few words and introduced each other.

Six quarters of the hour.

The gong sounded, the candidates began to sit down, distributed draft paper, and Chang Ying also found his position, numbered 077019, that is, No. 77 examination room, No. 19, I also had an understanding in advance, and later, this exam number must be filled in on the exam paper.

Confidently and patiently waited, and after about a quarter of an hour, accompanied by the sealed test papers escorted over, there was also a password from Lord Pingzhang, saying that in order to ensure the fairness of the examination, he demanded the confiscation of abacus, abacus and other items.

There was inevitably a commotion, but not much.

At the critical moment, it was Lord Heizhang who spoke in person, and no one dared to raise objections.

This has no effect on Chang Ying.

I began to study the book "Mathematical Foundations" related to Lord Pingzhang a long time in advance, and the written calculation method in it, in Chang Ying's opinion, was not slower than the abacus and other methods, and with an abacus, it was a burden for him.

However, as you can probably imagine, this is not good news for those who have deliberately worked hard to practice abacus before.

The abacus was confiscated, and the time was approaching.

Another gong sounded, and the invigilator personally opened the sealed test paper under the gaze of the plainclothes sergeant, and then handed it out, while reminding aloud: "All the soldiers fill in the name and examination number first, and browse it for a while, and then you can answer the paper......

Repeat this three times.

When the test paper arrived, Chang Ying immediately looked at it.

There are two test papers, printed on one side.

The first question, this is a question about the tax grain population, a total of two questions, the first question is very simple, the back is marked (2 points), the second question is a little difficult, but it is only a little more troublesome to calculate, the score is (8 points), a question, a total of 10 points.

Scan it again roughly, with a total of 10 questions and a total score of 100 points.

Back to the first question, Chang Ying almost subconsciously started to calculate, suddenly reacted, stopped moving, just seriously wrote his name and test number aside, put down the charcoal pen, and continued to browse.

Basically...... It's not hard.

Or it needs some complex calculations, or it needs lists, or it needs to draw pictures, and the key thing is, it needs to be careful.

If you don't pay attention, you can make mistakes.

On the other hand, in the whole volume, Chang Ying also saw a strong Pingzhang adult style.

This is obviously someone who personally came up with the question, and it is all related to reality.

After a quick sweep again, the gong had not yet sounded, Chang Ying inevitably looked around curiously, and did not look too blatantly, so as not to be suspected, but just swept it with his residual light, and the next seat on the left was obviously frowning.

Seem...... There was also the sound of cold air from behind.

Chang Ying felt a little funny.

If you think about it carefully, in fact, if you carefully study the book "Fundamentals of Mathematics" that has been widely distributed during this time, you can basically answer this test paper.

Draw air conditioning at the moment......

Either you don't have a bright brain, you can't read a book for a few months, or you just don't have the heart.

Well.

It could also be a posturing.

Thinking so, the gong sounded again, and the examiner's voice sounded: "Start answering the questions, pay attention to the time, and hand in the papers at noon......

Three times in a row.

Chang Ying had already picked up the charcoal pen and neatly wrote down the word "solution" after the first question, which is the standard process for such problems in the "Foundations of Mathematics", and Chang Ying did not miss the colon at the end.

Except for a slight rustle, there was silence in the examination room.

Chang Ying also quickly immersed in it, I don't know how long it took, it seems to be ...... It didn't take long for half of the questions to be completed.

As soon as I flipped to the second one, I felt that there was a commotion around me again.

Chang Ying looked up and saw a group of people walking slowly on the other side of the road, one of them wearing a red dragon robe, one on the left and one on the right, two young men who were much shorter.

Your Majesty the Emperor!

The invigilator's voice sounded again, and it seemed a little more solemn: "All the scholars answer the questions carefully, and you must not look left and right, otherwise you will be expelled from the examination room......

Chang Ying hurriedly lowered his head, and the commotion around him quickly subsided.

It's just that after a short moment, Chang Ying felt that someone had walked to his side, and there was a voice from Master Pingzhang: "Ancestor, this is Chang Tongzhi's son, a very good young man."

Then another voice laughed, "You ...... Speak in an old-fashioned manner."

Then, the middle-aged man in the dragon robe just now had already arrived at his side, and seemed to be looking at the exam papers, but Chang Ying had just turned the page, and the first question here had not been done yet, and he was ...... Because the emperor actually appeared beside him, his hands were also a little shaky.

God......

How can this be good, Your Majesty the Emperor...... Don't think you haven't answered a single question!

I wanted to move and reveal the paper I had answered, but I ...... and did not dare to move.

A small hand next to him reached over and helped him out of the siege.

Zhu Yuan took out the first volume that had been written from under Chang Ying's hand and handed it to Lao Zhu on the side: "Ancestor, take a look."

Lao Zhu took it and didn't say the answer, but it looked neat at a glance, which made people happy, of course he knew the answer in advance, and looked at the content, five questions, and one was right, and couldn't help but praise: "It's a good posterity."

personally returned the roll to Chang Yao, Lao Zhu patted it on the young man's shoulder, and said with a smile: "I still remember, on Poyang Lake back then, your father was quite brave, and when he came to you, he showed off his talents, and your Chang family was both civil and military."

Chang Ying felt even more trembling, and wanted to get up and kowtow to His Majesty the Emperor, knowing that it was not appropriate at the moment, she could only keep her sitting posture and bow her head deeply: "Thank you, Lord for complimenting."

Lao Zhu patted Chang Ying on the shoulder again, still with a smile: "Don't bother you, just do the problem well, your speed is a lot faster than others, you still have to be slower, be careful, this math is to be careful."

Chang Ying hurriedly agreed: "The Lord has ordered."

Waiting for His Majesty the Emperor to walk away a little, Chang Ying, who was already sweating on his forehead, dared to raise his head, but he happened to meet another somewhat cold gaze, which flashed.

It is the left phase.

Suddenly, it was also a wreck.

The Chang family still wanted to please both sides, at least not offend both sides, and at the moment, look at the reaction of the left...... While answering the question, Chang Ying was already thinking about sending another letter to her father after the exam.

I can only choose a side.

Fortunately, Lord Pingzhang, the moment is ...... It's not something that the left minister can handle at will.

Zhu Yuan didn't know that Li Shanchang behind him was already putting on Chang Ying's small shoes with his eyes, and if he knew, he wouldn't care too much.

For this left minister, Zhu Yuan has judged it very early, and the popularity is not large, but

, this time, many things have changed, not to mention himself, even Lao Zhu, will not let Li Shanchang mess around as before.

Speaking of which, the series of events from the third year of Hongwu to the fourth year of Hongwu, the main one, Yang Xian was sentenced, although there was an element of Li Shanchang's rejection of dissidents, but Li Shanchang obviously did not please him, and resigned from the position of Zuo Xiang due to "illness" in the second year, and returned to Zhongdu.

On the surface, this seems to be no problem, but in fact, Zhu Yuan feels that Lao Zhu's imperial attribute was awakened during that time.

Before that, Lao Zhu was still inclined to a local feudal town that had just conquered the country with his brothers and wanted to eat meat and drink wine together for a long time, however, with Yang Xian being impeached under the impeachment of Huaixi Xungui, Lao Zhu finally realized that the old brothers could no longer be allowed to exclude dissent so unscrupulously.

So, maybe it was a heart-to-heart push, or, with Lao Zhu's temperament, it was more serious, and he directly had a showdown with Li Shanchang, so Zuo Xiang was so frightened that he resigned due to illness.

Lao Zhu has always been an understanding person.

Evidence......

For example, in the famous conversation with Liu Ji about the choice of prime minister, most people may pay attention to Liu Ji's evaluation of Li Shanchang, Yang Xian, Hu Weiyong and others, however, Lao Zhu's words are equally intriguing.

This is a paragraph about Liu Ji's belief that Li Shanchang is more suitable to take charge of the phase.

Liu Ji thought that Zuo Xiang could reconcile the generals and unite the court, so Lao Zhu said, Li Shanchang framed you so many times, and he wanted you to die, I didn't expect you to support him.

Look, this paragraph.

The key is that Lao Zhu knows that Li Shanchang wants to kill Liu Ji many times.

According to the relevant details, this dialogue should have taken place before the resignation of Li Shanchang in the fourth year of Hongwu.

This is yet another piece of evidence.

It shows that four years before Hongwu, Lao Zhu was already very dissatisfied with Li Shanchang as prime minister. It's just that because they are old brothers who fight the country together, Lao Zhu doesn't want to bear the infamy of being a cunning rabbit and a dead lackey, so he has always tolerated it.

Until the fourth year of Hongwu.

After a vicious fight between Huaixi Xungui and Yang Xian led by Li Shanchang, Lao Zhu couldn't bear it.

After that, in fact, it can also be dissected.

About Lee Sun-cho.

Lao Zhu didn't want Li Shanchang to be the prime minister, so the Zuo Prime Minister had to resign from the official after saying that he was sick, which also shows that Li Shanchang is small-minded and does not tolerate others, but for Lao Zhu, he does not dare to have any disobedience, let alone rebellion.

Going deeper, losing his phase, and even being almost idle for many years afterward, Li Shanchang was very dissatisfied in his heart, but he didn't have any ruthless thoughts such as dying and breaking the net.

Without this talent, I dare not have this ambition.

Therefore, when he comes to Zhu Yuan, as long as he can ensure that Lao Zhu does not have problems, he has no fear at all.

In the exam room of the moment.

happened to pass by Chang Ying, and after taking the initiative to step forward and give the young man an opportunity, everyone continued to move forward, and Zhu Yuan also continued to talk about mathematics with Lao Zhu next to him, and the equally important, prince on the other side: "The math topics we are taking exams are actually very, very basic, and in the future, the proportion of mathematics must be increased, and it must be more in-depth. Because, not only in the governance of the country, but also in the country, the ancestors, and His Highness, at a deeper level, everything in this world can actually be quantified with mathematics, and in turn, in the future, if we want to understand everything in this world, we need to study mathematics more deeply."

Lao Zhu listened with relish, on the other hand, he knew in advance that it was Zhu Yuan who deliberately mentioned it today, and Zhu Biao, who could go out with his father, couldn't help but have a little more affection for the young people on the other side, and was also curious at the moment: "Yuan'er, everything in the world, is it exaggerated?"

Yuan'er ......

Zhu Yuan was still not very comfortable with this title, and there was nothing unusual on the surface, and said with a smile: "Your Highness, you can just say one and see if I can quantify it?"

Lao Zhu also looked at his son curiously.

cinnabar

Biao looked left and right, and was flashed by the rising sunlight, so he smiled and pointed over: "Yuan'er, the sun, how is the sun?"

Zhu Yuan said: "The sun, it's very simple, the first quantification is that the distance of the sun from us is about 150 million kilometers...... Well, if you change it to miles, it's about 300 million miles, which is a quantification. The second quantification, the temperature on the surface of the sun, is about 6,000 degrees, which we have not yet been able to reach on the earth, heh, Your Highness, I sent you a thermometer, 6,000 degrees, you can probably imagine it, right?"

Zhu Biao nodded, but he was curious: "300 million miles...... How do you know?"

"This ......" Zhu Yuan glanced at Lao Zhu, deliberately showing a tricky expression: "...... My ancestors can testify to me, and what I say is true."

Zhu Biao turned to his father.

Lao Zhu was unusual, touched his son's head, and said with a smile: "Yuan'er likes to talk about these mysterious things, I can't testify, you can listen to it roughly."

Zhu Yuan: "......"

Zhu Biao could also hear his father's joking tone, the kind between family members, in his heart, he thought of the big copper cabinet again, and secretly thought, sooner or later, he wanted to see what was inside, but he didn't show it on his face, just smiled and glanced at Zhu Yuan, who was embarrassed.

Zhu Yuan said helplessly, "Does Your Highness still want to listen?"

Zhu Biao nodded: "You say it in vain, and my aunt listens to it."

Zhu continued, "6,000 degrees Celsius is the surface temperature, and the core temperature of the sun, not ...... I forgot about it, it's about 10 or 20 million degrees, which is more than 100,000 times the temperature of 100 degrees in boiling water."

Zhu Biao was amazed, but asked again, "Why is it so high...... And, that ...... Shall we not smelt everything, and what shall we put it in?"
