Donggong Chaohe, not all civil and military officials participated-after all, the main hall of Ciqing Palace is slightly smaller than Wenhua Palace, and Wenhua Hall is several times smaller than Fengtian Palace, so it can't accommodate too many people here at all. Those who can come here to congratulate are only the civil and military ministers who are also officials of the East Palace, as well as the royal clan.

As for the civil and military officials, there was still a process of congratulating the prince of the East Palace on his ordination.

It's just that in the past, most of the princes who were younger brothers congratulated their eldest brother and crown prince, but the third prince was not the eldest brother at all, and the younger brother was only one of the four princes who were the commander of the light pole. So when the clan made a pilgrimage, the king of Jiangdu, as the elders, did not have to attend, so the kings were left with only two or three puppies and kittens.

That's right, in order to avoid going wrong, the emperor deliberately chose a clan that was the same generation as the third prince and the fourth prince to come to the East Palace to congratulate, and it was even younger than the fourth prince!

At this moment, six seven or eight-year-old children knelt on the ground, and the fourth prince led them to shout loudly: "Junior brother Zheng Qiang, it is very sad to meet my brother and crown prince to be honored with the treasure. I would like to congratulate Your Highness on all my brothers! ”

The Confucian scholar who was honored as the crown prince and master because of Jiang Ge's old age only felt that the corners of his mouth twitched. And Wu Gelao, who has always been the crown prince, smiled and nodded approvingly.

The crown prince next to him, Zhang Yu, was a thousand tastes in his heart, and his face was stiff or stiff. A few other officials who have taken up official positions such as the three young men of the East Palace, the young Zhan Shi of the Zhan Mansion, and even Liu Zhiyuan, who had just been stuffed with a Zhan Shi by the emperor, it was easy for him to keep a rigid face and not show too much expression. Don't look at the small people, all of them are clans, and no one can laugh at them!

And when the neatly dressed East Palace attendants lined up to meet them, they saw the mighty team of dozens of people, and thought of the news that the Son of Heaven had released a group of East Palace attendants to serve the prince in Ciqing Palace, and I don't know how many people wondered in their hearts whether they wanted to oppose it, and if they did, how to gather others to oppose it together, but this matter was too difficult.

Because as far as they know, not to mention that the emperor released a rumor, he first selected people in the Guozijian Frank Hall, so the Frank Hall, which was originally one of the six halls of the Guozijian, became a fragrant glutton.

Knowing that the Guozijian is rotten, but just because the best people from the Frank Hall can be selected as the attendants of the East Palace, they are eager to do it? Isn't that too humiliating?

Even Banshan Hall, which was already about to be moved out of the country and had been abandoned by countless people, was also allocated four additional places because the emperor was ready to encourage people to study and progress, and it is said that more than a dozen well-informed families planned to send their children and grandchildren over.

As for the Nine Chapters...... Jiuzhangtang, who was on the edge of the sword, had already occupied a lot of places in the East Palace, after all, he wanted the third prince to do his best to be admitted to it, and he studied from Zhang Shou, and even was classmates with many people. But even if there is really someone in your family who is highly talented, this next enrollment will have to wait until next year, and if you have the ability, you won't be able to get in!

At this moment, Lu Sanlang, who bowed at the head, and Qi Liang were from different backgrounds, but the excitement and excitement were exactly the same. Ji Jiu, who was slightly back in the back half, was also in tears, as for the others, whether they were from a fair background or from a humble background, whether they had spoken to the three princes in the past, or they had never dared to communicate with anyone, all in all, they were all stiff like marionettes.

If it weren't for Zhang Shou standing on the side, he would have been able to see this teacher when he raised his head, and I don't know how many people would kowtow one more or one less in a daze......

So, when the ceremony was over, the Confucius scholars almost escaped from the main hall of Ciqing Palace, which made him very uncomfortable, and most of the other East Palace officials also walked quickly, and in an instant, the place that was just crowded was left, and only the five clan children led by the four princes, the bear child, were left, and in addition to the people of the Jiuzhang Hall.

It's not that none of the other officials are willing to stay, but looking at the staffing in the main hall of Ciqing Palace, even Chen Shangshu, who is the crown prince and young protector, Zhang Shou's senior brother, and even Liu Zhiyuan, who has a good relationship with Zhang Shou, also followed the others and retreated according to the etiquette. Because they felt that if they stayed, they would raise the age level of the entire Ciqing Palace.

After all, even Chen Shangshu, who has always regarded himself as a middle-aged person, feels old when he is with Zhang Shou, let alone with those clan children who are not even ten years old.

And seeing that the annoying bosses were gone, the fourth prince suddenly shouted loudly with joy: "Third brother of the crown prince, I just asked the younger brothers, from now on, they will also stay in the East Palace to study." Although their qualifications are not as good as our brothers and classmates like Jiuzhangtang, they can memorize Jiujiu songs when they were children, and they are all good at arithmetic, and they are fast in addition, subtraction, multiplication and division! ”

He looked at Zhang Shou as he spoke, and said confidently: "Before we came in to pay respects just now, I personally took the exam, teacher, you have to believe me, I can still be competent in the superficial arithmetic examination!" ”

Several children have all been seen by the emperor during his years out of the palace, and the elders in the family are also in the royal family, so not only is no one rushing to speak at this time, but they are all standing there in a proper manner, looking quite calm, but it contrasts with the fact that the fourth prince is not stable at all.

But the fourth prince didn't care about this, he only knew that although he didn't have a younger brother and sister now, but with such a group of well-behaved younger brothers, he could finally put on the prestige of being an elder brother. Therefore, it was very natural for him to pull the clans one by one, enthusiastically introduce everyone, and let Zhang Shou personally examine it, so as to verify his vision.

Among them, there is Zheng Key, a nephew of King Jiangdu. Unlike the brothers who don't like to get ahead and hold the authority in the mouth of the lord of Hailing County, although this child is a little wooden, Zhang Shou casually tested a few complex addition and subtraction questions, and the speed and accuracy of the answers were given, and even the chickens and rabbits in the nine chapters of arithmetic could be answered casually.

This is not easy, you must know that although there is a trick to this topic, people are younger than the four princes after all!

However, after being asked three questions by Zhang Shou, his appearance was not surprising, and Zheng Key, who was very dull except for answering the questions, suddenly asked: "Teacher, I have always heard that you have a high attainment in arithmetic, and you are a close disciple of Old Master Ge. Can you tell me that the stars in the sky can really point out good fortune and bad luck? If so, why can't Qin Tianjian calculate from the astrological signs? ”

"And if it can't predict good fortune and bad fortune, and Qin Tianjian can't even count the stars and solar eclipses, etc., then what is the use of Qin Tianjian? So what's the use of us learning arithmetic? Is it only for auditing and auditing? Or compile ciphertexts for military intelligence transmissions? If it is only of such a small use, then how can arithmetic convince those scholars who read the history of the Bible? ”

No one expected that on this day of Chaohe East Palace, a young clan who seemed to be following the four princes suddenly asked such a question.

Thinking of how much impact it would have if this question had just been asked in front of Confucius University and others, Lu Saburo was afraid for a while. He didn't care about Zheng Jian is clan, even if his father was just a general of the town, it was not easy to bully, so he immediately rushed forward and scolded fiercely: "How can this be reasonable, how much arithmetic have you learned, and you dare to say that arithmetic is useless?" ”

Seeing that Ji Jiu was shaking his hands as if he was planning to follow Lu Sanlang to launch a counterattack, and Qi Liang was persuading the other indignant people, while the other young clans around Zheng Jian were all panicked and distanced from others, as if they were afraid of being killed by the pond fish, the four princes frowned, and they were furious, but Zheng Jian was still serious, and Zhang Shou couldn't help laughing.

"What's the use of arithmetic, that's a good question."

Zhang Shou understands that the readers of this year cannot be said to be without the spirit of questioning, because it sounds like a conservative and retro movement of various ancient texts, in fact, it is to oppose vulgar writing, and advocate that the text carries the Tao and give the article a more profound ideological content, but in fact, it is the most mainstream trend of articles at that time that is questioned and opposed. And this kind of questioning was had in the Tang Dynasty, the Song Dynasty, and the Ming Dynasty in history.

But generally speaking, in the academic circles of economics and history in these years, it is not advisable to question it. The classical doctrine of the saints is indisputable, and so are the scriptures and histories that are commented on. As for the students' doubts about the teacher...... That's sorry.

In most cases, the teacher is deceived and the ancestors are destroyed, and there is no teacher...... All kinds of big hats will be buttoned down on people.

Therefore, Zhang Shou gestured to signal everyone not to overreact, and said unhurriedly: "The sunset and the stars are sinking, in fact, it has nothing to do with good fortune and misfortune, but there is also truth in it. For example, the buoyancy experiment I once demonstrated to you in Mid-Levels Hall seems to be able to only check the fineness of gold and silver, and whether there is a mezzanine inside, but do you know that there are other uses for that? ”

"It is well known that wood can float on the surface of the water, while iron sinks to the bottom, and even if the iron is beaten into a thin layer of iron, it will sink to the bottom when placed on the water. But what about an iron box without a lid, if it is not a piece of iron, but a boxy, seamless seams, and no water will enter? Can such an iron box float on the water? ”

"And it is also well known that if you drop an iron ball and a feather at a high place, the iron ball will hit the ground instantly, but the feather may float away with the wind, but if you drop a very heavy iron block and a small iron ball at the same time at a high place, what will land first?"

"The sky is round, so why do you see the sails of the ship first and then the hull when you look at the big ship entering the harbor in the harbor?"

This kind of 100,000 why-like questions are not unfamiliar to the three princes and the fourth princes who have stayed in Banshan Hall at all, and the people of Jiuzhangtang are also familiar with Zhang Shou's explanation because they were exposed to arithmetic at the beginning, and later added relatively simple physics. However, for a group of little kids, these are the reasons that make them very excited.

In terms of Zhang Shou's way of speaking just now, that is...... It's also a well-known fact that children are the ones who love to ask why!

Even if the children of rich and noble families are enlightened and knowledgeable early because they are enlightened and enlightened, so they are sensible early - this is different from the children of the poor who are in charge of the family early, one is to know the hardships of the world early, and the other is to know the world early - so this group of clan children can suppress the uneasiness and curiosity in their hearts, and behave like adults when they just went to the East Palace, but at this moment they couldn't help it one by one.

Regardless of the fact that this was Ciqing Palace, their parents told them to be respectful, and one of the children couldn't help but ask, "Does the teacher have answers to those questions just now?" ”

"Of course I do." Zhang Shou smiled, but threw out a hook, "But I can only tell you part of it." ”

Lu Sanlang's eyes were already wide, and he even began to look left and right, looking for something that he often saw, but which might be there in this Ciqing Palace, but it was probably not there. But he soon discovered that the third prince, who was shy and shy before, had a slightly sly smile on his face at this moment. And the next moment, he understood why this sly smile was.

Because just after Zhang Shou asked Zheng Jian a bunch of whys, and then was asked why by a group of clan children, a few sturdy men moved in a piece of something that the students of Jiuzhangtang were all too familiar with - a few blackboards!

And then, Zhang Shou, who seemed to have expected the third prince to have this kind of preparation, took the white pen from one of the men with a smile, and then bowed slightly to Zheng Key: "You just asked me what arithmetic does, so now I will show you how the iron box can float on the water." ”

Seeing that Zhang Shou used xyz to mark the length, width, height and thickness of the iron box, and then calculated the area of the iron sheet for making the iron box, he then used the rough fine iron density measured in the Tiangong Workshop to start calculating the weight of the iron box, the buoyancy required to float on the water, and then preset the depth of immersion in the water, and began to reverse the volume of the iron box submerged in water...... Everyone in the Jiuzhang Hall reacted steadily, but a group of children from the clan were completely stunned by the equations on the whiteboard.

God is pitiful, even the children of future generations will never be exposed to such difficult content at the age of seven or eight!

However, after writing a few formulas, he turned his head to look at Zhang Shou, who was reacting to everyone, only to find that Zheng Key, who raised the question, the nephew of the king of Jiangdu, was staring at the whiteboard, as if he was just trying in vain to understand these strange things, and as if he understood or not, at least he had to memorize these formulas.

Of course, it could also be that a genius was grasping that light.

When Zhang Shou finished writing the whiteboard in front of him and roughly deduced a formula, he casually handed the charcoal back to the big man on the side, and then said lightly: "That is to say, under ideal conditions, what can float in the water is not only a light object like wood, but also a steel giant!" If you add the installation I demonstrated at the Mankaden Sutra Banquet......"

On this day, when this group of children from the clan left Ciqing Palace, they were either lost or excited. What Zhang Shou depicted in front of them, if it was those adults whose three views had been stabilized, they would naturally be scolded in person, and some people would even denounce it as a demon law, but children will naturally believe in all miracles that fly into the sky and the earth and are omnipotent.

Everyone thinks that it was originally just a careful study with the prince, but it turned out to be quite interesting! Moreover, their future teacher promised that they could casually ask why in the future, and if he couldn't answer, everyone could discuss it together!
