Everyone knows that Han Gang's first class was not to teach the prince to read, but to show the emperor and empress. But no one expected Han Gang to take such a class.

Cai Bian frowned, staring at the teaching record on the table.

Guozijian is closely connected to Zishantang, and several lecturers have also worked as errands in Zishantang, and Cai Bian is also one of them.

Although he didn't listen to Han Gang's first class with his own ears like his colleagues on duty. But not long after the class, the three questions that stayed in the hall were passed from the imperial city to Cai Bian of Nanxun Gate.

The classroom next door is like a kettle on the stove, bustling with activity. A group of Guozi prisoners were arguing over Han Gang's topic.

"What is this called! What is the question called? There are a few in the national prison that can be made. ”

"If nothing else, the prince is only six years old. Bai Lotian can recognize 'nothing' at the age of half a year, but he can't write 'this hatred is endless' when he is six years old. ”

"Didn't you hear the last sentence that Han Shumi said? You can ask people! What officials and saints want is not a gentleman, but a prince. Han Shumi also wants to teach the prince the truth of listening and understanding. ”

"It's a habit of selling vegetables. He sells what the guests want. ”

"How many families hire Mr. Xixi, don't they plan to teach a jinshi and the first to come out? What emperor doesn't want a promising crown prince to inherit the throne? ”

"It's too much. Do you want me to count them for you? Emperor Wu of the Han Dynasty and Emperor Taizong of the Tang Dynasty ......"

"Don't lift the bar. Han Wu has paralyzed ......"

The students spoke unscrupulously, and although they swallowed the last half of the sentence, they were still rebellious enough. If you really want to think about it, you can reprimand the great disrespect of the public opinion. The person who said it had a share in the killing, and the person who listened was inevitably exiled.

Cai Bian moved his body and wanted to stand up and reprimand, but he held back, just remembering the names of a few people outside.

Taixue three houses, outer houses, inner houses, and upper houses. If you don't go up to the inner house and the upper house, don't think about being an official. Just let them rot away for the rest of their lives.

"What are you arguing about, Zong Rulin really put it out over there."

Just when Cai Bian was listening to the noise next door, Zong Ze found a ruler and a hammer from the carpenter next door who was rebuilding Sima Temple, as well as a ball of ink thread, and fiddled with it for a long time. I recreated the experiment in the classroom.

However, the ruler was not on the edge of the table, but on Zong Ze's fingers.

Looking at the shakutsu hammer on Zong Ze's fingers that was crumbling but couldn't be dropped, the classroom fell silent.

The previous Guozi prisoners were all arguing about Han Gang's intentions, but when they saw the incredible real thing with their own eyes, everyone would want to know what this was about.

"Since Han Shumi has set up a position, he must want the prince to find someone to answer. I don't know what Mr. Wang Pingzhang and Mr. Bochun can say about this. ”

Zong Ze said, his voice was not loud, but it came out clearly.

Cai Bian's hand sank, which was exactly what he was worried about now.

Han Gang's teaching is clearly aimed at Wang Anshi and Cheng Hao. If the two families avoided it, what would the emperor think at that time? What would the queen think?

……………………

Empress Xiang was at a loss, with the same expression as the princess of Shu who spoke to her.

The questions Han Gang came up with on the first day of class made them all confused.

Han Gang's question must have a deep meaning, but it is just incomprehensible. And the answer on the bright side is also difficult to calculate.

"It's easy to say that the question from one plus one to one hundred should be to grind the sixth brother's temperament." Queen Xiang seemed to be talking to herself, and seemed to be talking to the princess of Shu, "The sixth brother has been smart since he was a child, and after going to school, he will learn everything as soon as he learns, and it is not necessarily a good thing to be smart and exposed, it is good to know how to be restrained." If you can sharpen your temperament, it won't be bad. ”

"The sixth brother is much smarter than my eldest brother, maybe it will come out in a moment."

"It wasn't easy. Add it step by step, a full hundred steps, and if you make a mistake in the middle, you will be completely wrong. The sixth brother is sometimes confused, and yesterday he memorized the Analects, and he jumped a sentence on his back. ”

"That's right. Don't be smart, just be careful. ”

nodded to the queen, and said, "But the hammer and ruler, like a trick, are completely incomprehensible." ”

The princess of Shu doesn't understand, if you don't add a hammer, the ruler will definitely fall off, and if you tie the hammer, it won't fall off. If it's a trick, no matter who does it, it's the same result. And Han Gang was not there yet. What trickster can change like that?

As soon as Song Yongchen came back to say, he waved his hand again, and shook his head when he asked anyone in the palace.

However, Han Shumi specifically said that he could ask people. Wang Pingzhang, Cheng Xiushu and Han Shumi are in Zishantang, and it is said that they are fighting for what kind of Taoism, maybe Han Shumi is writing a war letter for Wang Pingzhang and Cheng Xiu. ”

"Then you can't do this problem?"

Regardless of status, regardless of character, only talking about learning, Wang Anshi and Cheng Hao are both world-famous Confucians. Han Gang took the title of the war book, and there was really no one in the palace to do it. Even in the DPRK and China, there may be people who have this ability.

Xiang didn't think much about it, just waited for the result, and it was only two more days. If Wang Anshi and Cheng Hao can be asked down, it won't be bad. This can also let people know who is the most suitable prince.

As for the question of putting wheat grains on the chessboard at the back of the game, Xiang thought about it for a while.

The number of wheat grains at the end of the last should be a lot, so Zhang Dian and Shen Kuo did not bet. Both are highly knowledgeable and will not be fooled. If you can't say it, there may be hundreds of stones.

But she always felt that it was not so simple.

Queen Xiang likes to play chess very much, but probably because she rarely loses, her level is not high. She also realized that after all, no one dared to win her lottery. However, this did not affect her interest in play or chess.

Han Gang's chess skills are also not high. She had heard a few words from Wang Yi. Han Gang, who is not high in chess skills, can make Zhang Dian and Shen Kuo dare not gamble, and the result of losing will definitely be unaffordable, and it may even be too much to lose, and he will not dare to take risks.

"It is also possible that Han Shumi bluffed and deliberately deceived people." The princess of Shu guessed, "Wheat is really worthless compared to hundreds or thousands of dollars, but it makes people suspicious." ”

One or two grains of wheat, even if each grain is doubled to sixty-four squares, it will certainly not be much more. Compared with the lottery head given by Han Gang, it was too far behind, which made Zhang Dian and Shen Kuo suspicious in their hearts, and they didn't dare to gamble rashly.

"Like before the cup opened?" Asked the Queen.

"Sort of." The princess of Shu said.

During the New Year's holidays, the boudoir gambled on the lottery, and Queen Xiang and the princess of Shu did not play less when they were young. also knows that Lu Dao is on the gambling table, even if there is no bottom in his heart, he must pretend to be confident. Sometimes the most noisy and noisy is the most empty-hearted.

However, Empress Xiang felt that Han Gang would not be so simple. The means of bluffing, after all, are not elegant, and should not be used as a lesson for the prince.

"I have already told Song Yongchen to find the number of grains. See how many there are. It should be soon. She said.

Song Yongchen came back much later than expected.

Empress Xiang was already waiting a little impatiently, frowning and asking, "How many are there?" ”

Song Yongchen owed, his cuffs trembled, and some wheat grains were shaken, "Saint, there are as many as 50,000 grains in one combination." ”

Song Yongchen really asked people to take a piece of wheat and count it. There was not just one, but seven or eight people counted their own. Counted the whole day. The numbers reported were very chaotic, ranging from more than 10,000 to 100,000, and when you looked at it, you could see that some people didn't care at all. But to double-check, there is not enough time. However, he didn't dare to say that the person he was looking for was unreliable, so he compromised and quoted 50,000.

Fortunately, Empress Xiang and the princess of Shu did not suspect it.

"Ten buckets, ten buckets and one stone. There are five million in one stone of wheat. The princess of Shu smacked her tongue lightly and smiled at the queen: "It seems that Zhang Shumi and Shen Kuo were really bluffed by Han Shumi." ”

If you want a stone of grain, you can really have 5 million grains of wheat, and each of the 64 grids can be divided into nearly 100,000. Even if you put wheat grains according to what Han Gang said, the more you put them in the back, but at the beginning there were only one, two, four, and eight grains.

But I don't know what to do, Queen Xiang still thinks it's not that simple.

"Wait for Liu Weijian's news."

Song Yongchen counted the wheat, but when it came to calculating how many wheat grains to put on the chessboard, Xiang asked the queen Liu Weijian to calculate. Liu Weijian is now in charge of the Zuo Zang Library, proficient in the art of Qian Gu.

However, Liu Weijian came back later than Song Yongchen.

"Why is it so late?"

"Saint, after the slave and maid calculated one side earlier, I felt that the result was incredible, and most of the heart was miscalculated. So he went to Si Tianjian and asked Si Tianjian to help. Who knew that the winter official on duty in Si Tianjian had calculated it, but it was exactly the same as that of the slave maid. ”

Although Si Tianjian is superfluous and his level is so poor, his basic skills are still a little bit. Otherwise, Liu Weijian would not have gone to them.

"Unbelievable?" Xiang looked at the chessboard on the side of the queen and asked Liu Weijian, "How many wheat grains do you need to fill the chessboard?!" ”

Liu Weijian took out a roll of paper from his sleeve, unfolded it and read it: "Enlightened Sage, when it reaches twenty-eight squares, it will be more than 100 million [Note 1], 13,4217,728. Twenty-seven squares back to fifty-five squares, which is one hundred and thirty thousand four hundred seventy seven hundred and twenty-eight, one hundred thirty four thousand two hundred seventy seven, eight times. And at the sixty-fourth grid, it is five hundred and twelve times that of the fifty-fifth square: nine hundred and twenty-two trillion and three thousand three hundred and seventy-two thousand three hundred and sixty-eight billion and five four hundred and seventy-five thousand eight hundred and eighty. This is just one square, and if you add up all the sixty-four squares on the board, it is twice as many as the sixty-fourth. One thousand eight hundred forty-four trillion and six thousand seven hundred forty four thousand seven hundred and seventy seven hundred seventy seventy two thousand six hundred and fifty thousand six hundred and fifty ......"

The princess of Shu was completely stunned, Liu Weijian's tongue twister-like number she was confused when she heard it, but no matter how confused she was, she knew that this was a terrible number.

More than 130 million more than 130 million more than 512 times! Multiply by two more, minus one!

It's just sixty-four squares! How did it become so much?

Empress Xiang was also stunned for a long time, and then she was surprised and lost her voice: "So much!?" It's just a sixty-four-grid chessboard, not counting the Chu River and Han Realm in the middle! ”

The annual income of tens of millions of stone taels of the imperial court is converted into money, which is worth millions of dollars. In the eyes of the queen, it is already a huge amount. But this number is 100 million times worse than the grain of wheat on the chessboard.

"One stone of wheat, five million grains! How many stones are there? ”

Liu Wei made a rough calculation: "Three trillion stones is more." ”

Empress Xiang felt even more in a trance: "How many years is enough to eat?" ”

"The population of the world is more than 100 million, and one person eats four stones a year. It's only four or five billion stones. Let's not talk about six or seven thousand years. Liu Weijian didn't know if Lu Dao was right, anyway, no matter what happened, it wouldn't be less than a thousand years.

Empress Xiang was stunned for a long time, and Fang Hui came back to her senses and smiled bitterly at the princess of Shu: "No wonder Zhang Shumi and Shen Kuo refuse to gamble with Han Shumi, even if the official family is bankrupt, they can't afford to pay for it." ”

The princess of Shu also smiled bitterly and said: "Hundreds of thousands of dollars of grain against trillions of stones, Han Shumi is really good at teasing people." ”

Zhang Dian and Shen Kuo can see through it at a glance, and when it comes to intelligence, it is actually not bad. It's definitely out of reach. He nodded to the Queen.

In any case, this is much more euphemistic than a direct recommendation from the table.

Note 1: It is recorded in the Eastern Han Dynasty's "Records of Numbers" that in ancient times, there were three methods of advancing the number in the upper, middle and lower: the lower number is progressively in ten, ten trillion is billion, one billion is the trillion, and ten trillion is the capital; Tens of trillions are billions, trillions are trillions; Hundreds of billions of trillions are trillions, and trillions are Beijing. The common one is generally the lower number, but here for the sake of convenience, the middle number is chosen.
