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.
