The two old men sat in the hall and looked at Li Chengzhi with great curiosity.
The one on the left is Liu Fang, the one on the right is Cui Guang.
Other courtiers only knew something about Li Chengzhi through the memorials of Xi Kangsheng and Gao Meng. However, Liu Fang and Cui Guang had many contacts with the Guanlong family, especially the Li family in Longxi, and their disciples were all nearby.
At that time, they accompanied Gao Meng to Jingzhou and even met Li Chengzhi, so they needed to know more about him and knew that Li Chengzhi was really capable and could be called an all-rounder.
Upon hearing that Li Chengzhi was appointed by the emperor as Hou Xinglang, these two people could not help but be curious: Could it be that Li Chengzhi's stargazing and divination skills are as amazing as his poetry and general talents? p>
That's why this scene happened.
Li Chengzhi was also a little worried: As soon as he entered the yamen, he was summoned by these two people. I don’t know if it was a good thing or a bad thing? After all, when he was in Jingzhou, he had not been very happy with these two disciples. p>
He was also mentally prepared: it was no big deal if he was ridiculed a few times, as long as he didn't curse.
First, Liu Fang and Cui Guangjun are both well-educated people. No matter how arrogant they are, they would not dare to pretend to be superiors or speak big words, otherwise it would be just like a joke.
Secondly, these two are both loyal and upright people. In the process of Yuan Hong's Chineseization, in order to improve the status of the Han family and make the people of the Han family live a better life, they worked hard and exhausted their thoughts.
Hair. For this alone, it would be difficult for Li Chengzhi not to respect him.
After being silent for a while, Cui Guangcai said curiously: "To be able to be personally named Hou Xingtian by His Majesty, you must have some ability. I guess you are already proficient in the Gan Jing and Xing Jing?" p>
Li Chengzhi was a little confused.
He only knew that these two books were the earliest systematic astronomical masterpieces in Chinese history, but he had no idea what was written in them.
Li Chengzhi replied honestly: "I've never been used to it!"
Haven’t even studied these two books?
Cui Guang was stunned for a moment, then asked: "You must have been studying "Five Star Divination" and "Book of Heavenly Officials" for a long time, right?"
Li Chengzhi was even more confused, his head shaking like a drum.
At least he knew that the second book was written by Sima Qian and was about early Chinese astrology. He had never even heard of the name of the first book.
So where did Li Chengzhi learn the art of stargazing and divination? I’ve never heard of this family tradition of the Li family in his ancestral home?
Liu Fang was surprised and asked: "Is it possible that it is really a gift from God's wisdom, that one can learn by himself without a teacher?"
Li Chengzhi was so shocked that his hair stood on end.
Who the hell spread this?
People will die...
"The temple minister clearly sees that this is definitely a rumor!"
Li Chengzhi could not sit still, but stood up immediately, "I am even more frightened... To be honest with you, I know nothing about astrology or divination. I can't even figure out why Your Majesty clicked on it."
The official 'Hou Xinglang'?"
The two old men were shocked: Does this mean you don’t know anything?
Then what does your Majesty mean by granting you this official position?
After pondering for a while, the two looked at each other, and when they saw the smile in each other's eyes, they knew they had guessed it: So that's it?
If we say that the most unpopular and boring department in the capital is the eunuch, it is not even comparable to the imperial mausoleum. At least you can hunt while guarding the mausoleum in the mountains, but this Hou Xinglang can only blow the cold wind...<
/p>
After working for a long time, Li Chengzhi was actually assigned to the eunuch?
Look, you’ve learned a lesson, right? You, a young man like Gao Zhao, can offend you, right?
Do you still dare to say that you "want to marry both of them"?
If you don’t sit on the wax, who will sit on the wax?
The more Cui Guang thought about it, the funnier he became. He couldn't help but joked: "It doesn't matter, just think of it as learning... I heard that you are proficient in all six arts and are familiar with all schools of thought. Poems, songs, and military training are not a problem. Now you will
Now that you have mastered astronomy, astrology, and divination, who would dare to say that you, Li Chengzhi, are not an all-rounder in the future?"
Is this praising me or scolding me?
Li Chengzhi cursed secretly in his heart and replied angrily: "The wine sacrifice is too good. At most, I have read a few more books in my spare time. I never dare to call myself 'proficient'!"
Quite modest?
Liu Fang smiled and said seriously: "Although Chang Ren's remarks were joking, there is some truth in them. If we don't move you out of the eunuch, you can't waste your time here and mess around.
How about making a living? It’s also good to learn one more skill... Let’s learn math with a doctor of calculators first..."
Li Chengzhi was stunned at first: What the hell, why is it related to arithmetic?
After a moment's thought, he suddenly realized: This eunuch's life is inseparable from arithmetic.
Regardless of astronomy, calendar, astrology, divination, etc., we must first calculate the movement patterns of the sun, lunar moon, five elements and twenty-eight houses before we can make inferences and calculations. It can be said that no one can do anything without mathematics.
But the problem is, I have been studying for almost fifteen years in elementary school, junior high school, university... in total, and I still have to study after traveling through time. Is it so hard?
Seeing him stunned, Liu Fang asked suspiciously: "What's wrong?"
Li Chengzhi was so excited.
If you dare to be humble now, you will definitely get the result of being forced to learn the four arithmetic operations of addition, subtraction, multiplication and division.
He gritted his teeth: "I don't dare to deceive the temple minister. I still have some experience in arithmetic!"
How much do you feel?
Hearing this sentence, Liu Fang and Cui Guang suddenly thought of what Li Shenjun and Yang Shen had said: before the competition with Yang Shen, when Li Chengzhi talked about the skills of hundreds of craftsmen and military formations, he also said, "How many things are there?"
"Distracted"?
But what is it actually?
Throughout the Yuan and Wei dynasties, there were really few people of his age who could surpass him in these two areas...
It seems that he is quite knowledgeable in arithmetic, but he has never heard of it?
Cui Guang looked at him suspiciously: "Have you really learned it?"
Li Chengzhi nodded heavily: "I really learned it!"
He must have learned it before, but Li Chengzhi just didn’t know which stage he was at at this time.
There must be Pythagorean theorem, it is all knowledge from the pre-Qin period, including the multiplication table.
Zu Chongzhi must have been dead for several years, and pi must have been studied to seven digits after the decimal point, but it has definitely not spread to the Yuan and Wei dynasties. Otherwise, why would the court need to go to such trouble to reintroduce the calendar?
Wouldn't it be more useful to directly copy Zu Chongzhi's "Daming Calendar"?
Li Chengzhi doesn't know the rest. He is not afraid of being stumped by Liu Fang and Cui Guang, but he is afraid of being too ahead of his time and scaring these two old men.
This chapter is not over yet, please click on the next page to continue reading!
I really want to attach myself to the label of "God's wisdom and divine guidance, self-taught without a teacher", and there will be no place to cry when the time comes.
Li Chengzhi took a sneak peek and then said cautiously: "How many questions will there be if there are no questions about the wine sacrifice?"
"Yeah, that's fine!"
Cui Guang nodded and pondered for a moment: "Now there is a round log buried in the wall. I don't know the size. I saw it with a saw. It is one inch deep and the saw path is one foot long. What is the diameter?"
Li Chengzhi breathed a sigh of relief: I just thought of the Pythagorean Theorem, isn’t this coming?
Even if you have graduated several years ago, how can you forget such a formula?
He calculated silently and checked it twice. It took about ten breaths and only half a minute to get the answer: "It should be two feet and six inches?"
Liu Fang just thought that he had actually studied the Suan Jing and read the questions, so there was no difference. He just nodded slightly to indicate that you remembered it correctly.
But there was a trace of doubt in Cui Guang's eyes: Li Chengzhi clearly didn't remember it, but calculated it...
He calmly asked again: "Today, I want to look at the island. I have two tables standing, three feet high. They are a thousand steps away from each other, so that the back table is in line with the front table. In the past, I walked a hundred and twenty-three steps, with my eyes on the ground."
Take the Wangdao Peak and join it with the end of the table. Walk one hundred and twenty-seven steps from the back of the table. With your eyes on the ground, take the Wangdao Peak and join it with the end of the table. Ask the height of the island and its geometry from the table?"
Li Chengzhi is a little curious.
This involves the sine and cosine theorems of triangles. It should be mathematics knowledge in the third grade of junior high school, but it is already available in this era?
Of course, such a question would definitely not be difficult for exploration major Li Chengzhi.
It is also as big as ten breaths, and Li Chengzhi gave the answer: "The island is four miles and fifty-five steps high; it is one hundred two miles and one hundred and fifty steps high."
Cui Guang stared at him intently and asked another question without breathing: "Today there is one chicken, worth five; one hen, worth three; three chicks, worth one. A hundred dollars can buy a hundred chickens."
, ask the rooster, what are the dimensions of the mother and the chicks?"
Haha... Li Chengzhi almost laughed out loud, isn't this a chicken and a rabbit in the same cage... Oh no, it might be a little harder.
The chicken and the rabbit in the same cage is a linear equation of two variables, but this question is a system of indefinite equations of three variables, with multiple answers.
But it’s not difficult. If you were a smarter primary school student, you should be able to calculate the series and multiplications even after eliminating them, but it just takes a long time to complete.
To make an equation, Li Chengzhi couldn't secretly write it down in his sleeve. He thought about it and felt that these two people would never understand it anyway, so he stretched out his hand openly and started drawing in the palm of his hand.
:
x y z =100……
5x 3y (1/3)z =100, (1/3)z is an integer...
He was still muttering: "Let the official do the math..."
Liu Fang finally realized something was wrong: This Li Chengzhi didn’t need to calculate anything?
He asked in surprise: "What's your algorithm?"
Li Chengzhi lied without blinking: "It's just a calculation, but the official has a good memory, so there is no need to calculate..."
I can recite the Five Classics backwards and forwards, but why can’t I have the same ability as you?
Are you lying?
Liu Fang twitched his beard and was about to ask a question when Cui Guang winked at him.
It means don’t be impatient first, take a look before talking.
He had long realized that something was wrong: these three questions were all classic questions in Sutra calculation. If Li Chengzhi had really practiced Sutra calculation, and he had a good memory as he said, he would definitely have remembered the answers. Naturally, he would have just blurted them out.
No need to calculate.
And if it can be calculated, at least the last two questions must use calculation chips, but Li Chengzhi just uses his fingers to calculate?
At this point, how could Cui Guang not see that Li Chengzhi was not only lying, but also had some new solution?
The two old men didn't speak, they only made eye contact, and after a few breaths, they both smiled sinisterly.
No matter how good you are, no matter how good your disguise is, it will still be exposed under my nose.
Li Chengzhi was immersed in calculation, but he didn't expect that the two old foxes had already seen the flaw. This time it took longer, about thirty or forty breaths (two minutes), and he gave three sets of answers:
"The fourth son is worth twenty; the mother is eighteen, worth fifty-four; the chick is seventy-eight, worth twenty-six.
The youngster is worth forty; the mother is eleven, worth thirty-three; the young is eighty-one, worth twenty-seven.
The twelve youngster is worth sixty; the fourth mother is worth twelve; the young eighty-four is worth twenty-eight."
It’s so perfect and so fast?
Liu Fang and Cui Guang were surprised, but their faces didn't show it at all.
Li Chengzhi really got it right: Even Cui Guang needed to use calculations to list the multiplications and then eliminate them one by one to solve this problem. Moreover, there were quite a lot of multiplications, and the minimum time it took him would be more than half a moment. p>
If you say you don’t need to calculate... then it’s absolutely impossible. Who has such a good memory?
If Li Chengzhi doesn't have a new solution, they won't believe it even to death...
"Do you really have some experience?" Cui Guang asked meaningfully.
Li Chengzhi couldn't hear the sarcasm in his words, and he smiled modestly: "The wine sacrifice is overrated, it's just that the lower official has a better memory..."
Liu Fang almost slapped him in the face.
At first glance, he looked like a slippery man, and he was afraid that even if he pressed him, he wouldn't be able to get anything out of him. After pondering for a while, he asked again: "Which city do you want to go to?"
Li Chengzhi was overjoyed: Is this still a choice?
Before coming, he also made a point of finding out: the eunuch Hou Xinglang had a maximum of twenty people, and he was just one of them.
The twenty-year star ministers each have their own duties: the sun, lunar calendar, five elements, twenty-eight palaces, etc. In addition, they are divided into ten members, belonging to the two prime ministers of Taili and Taibu.
The former deduces the agricultural seasons of the calendar and the twenty-four qi of the four seasons, while the latter predicts good and bad fortunes, auspicious days of the zodiac, and even interprets dreams for the emperor?
Believe it or not is a secondary matter. The key to this business is that if you are not careful, you will lose your head. Li Chengzhi knows which one is better with his toes.
He bowed down and said, "I really don't know anything about the art of stargazing, so I chose Taili. It would be best if I didn't do stargazing. It would be better if I had the job of arithmetic..."
Tai Li Cheng is great, maybe we can work out which day it is in the Gregorian calendar. Regardless of the rest, at least there is no need to determine the leap month.
Or perhaps ask Nan Chen, who is returning to the north, if he can get the "Da Ming Calendar" from Zu Chongzhi's son so that Liu Fang and Cui Guang can learn from it.
I don’t know the rest, but at least Li Chengzhi knows that the calendar created by Zu Chongzhi is the most accurate of all the calendars before the Yuan and Ming Dynasties...
The two old men almost sneered: Is that a lot to ask for? If it had been anyone else, they would have been beaten with sticks...
"Okay, it's up to you!" Liu Fangfeng nodded calmly, "I'll allow you to take a day off today and see things again tomorrow morning (7 a.m.)!"
Is there really no need to go for a hair dryer?
It's okay in summer, but when winter comes, it's really not a sin that humans suffer...
Li Chengzhi secretly rejoiced: "The lower official thanked the temple minister and thanked the sacrificial wine..."
"Well, go ahead!" Liu Fang waved her sleeves.
After Li Chengzhi left, the attendant closed the door for them, and Liu Fang asked suspiciously: "Brother (the two are cousins), can you see what algorithm Li Chengzhi used?"
"It was too confusing to see clearly, but what he was reciting silently was indeed the Jiujiu Song..."
"Jiujiu Ge? That should be his own algorithm... No wonder he can create his own military formation technique?"
Liu Fang sighed softly, "This Gao Zhao is really doing a lot of harm to people. He is so talented, but he can't give full play to his talents?"
According to his opinion, no matter how much Li Chengzhi knew, he could not make as great a contribution as a pastoral defender or a convoy, but he was forced to be suppressed by Gao Zhao in the eunuch?
Cui Guang smiled: "That may not be Gao Zhao's intention. Don't forget, Li Chengzhi knocked out King Ruyang's tooth just the day before yesterday..."
Liu Fang was stunned.
He really forgot about the emperor.
"This temper is indeed a bit irritable, it might as well be tempered!"
"This is very true!" Cui Guang echoed.
As for whether there would be any problems in not letting Li Chengzhi go stargazing, the two brothers were not worried at all.
When you get to your own one-third of an acre of land, if you can't even be the master of this, how can you be a sacrificial wine and temple minister?
