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?

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.

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?"

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 be continued...
