Li Tai looked confused, is that so? Why couldn't he figure out what was the relationship between these things? In the end, can we figure out whether the people have cultivated the land?

After reading it, Li Ke frowned, he directly picked up his pen and wrote a note on the desk in front of him, and then handed it to Li Taidao: "Qingque, you personally go to Hanguang Gate, there are Tian Meng's people guarding, you give him this, let him pass it to Tian Meng, and investigate it as quickly as possible." ”

"Yes!" Li Tai simply ran away with the note.

Li Ke looked at the things in his hand, then raised his head and said, "You go down first, tomorrow you will have a day off, and then be ready to take over the relevant work at any time." ”

"Yes, Your Highness." Ning Quan immediately bent down and turned to leave.

"Go, call Huangfulin over." Li Ke put the things in his hand aside, and then called a little eunuch over.

"Yes!"

The distance between Huangfulin and the Liangyi Hall is not close, it just so happens that today is the day of rest, and tomorrow is the day of the upper dynasty, so you have to call Huangfulin from home.

Li Ke was not surprised at all by the problem of the Ministry of Civil Affairs, because of the problem of account records and Chinese character records in ancient times, it was much easier to fake accounts than in modern times, and many people may not be able to find problems in accounts for decades.

Especially when the study of ancient mathematics is still very difficult, in fact, the study of mathematics in ancient China is not weak, but Li Ke has read the mathematics books of this era, and the study of mathematics is not weak, but it is too difficult to learn mathematics in ancient times.

Because many ancient literary classics do not have punctuation, and in order to save paper and other books, they have repeatedly saved words, and the same is true of ancient mathematical classics.

And in this era, no one has given you a systematic summary of mathematics, from shallow to deep, from simple to complex to teach you step by step, and the ancient study of mathematics is relatively chaotic.

This results in the fact that the threshold of mathematics in ancient times was actually very high, at least to learn and master it very highly, and for people who only know ordinary mathematics, it is very scary to want to completely check the bill and calculate such a huge amount of calculations.

This is the power of the times, many people have studied the highest mathematical achievements in ancient times, and feel that modern mathematics is not much more advanced than ancient times, but in fact, whether a certain discipline is advanced or not does not depend on how deep its high-end achievements are.

Rather, it depends on whether it has formed a complete teaching system, whether it has a complete proof process, especially in mathematics.

In fact, the corruption in the Ming and Qing dynasties is easier to investigate, and it is also related to the progress of mathematics, and the mathematics of the Ming and Qing dynasties has been counted, including abacus and other calculation methods in the Ming and Qing dynasties are also more complete.

After all, the abacus was gradually perfected at the end of the Tang Dynasty.

It was almost an hour before Huang Fu Lin arrived.

"I've seen Your Highness." Huangfulin didn't know what Li Ke had asked him to do.

"Look at it, this is what my people calculated, the accounts of the household department in the past few years are missing." Li Ke asked Chang Lin, who had returned, to hand the accounts copied by Li Tai according to the Tang Dynasty to Huangfulin.

Huang Fulin was stunned for a moment, but he still took it, but when he finished reading it, Huang Fulin's whole body broke out in a cold sweat, and he knelt directly on the ground: "Your Highness, the minister is guilty, and the minister's supervision is not strict, but the minister is completely ignorant of these possible corruptions." ”

"Get up, I know this has nothing to do with you." Li Ke waved his hand lightly.

Although the Huangfu family is not a big family of gate valves, it is not too weak, and when it comes to the position of Shangshu, in Datang, there is really no need to embezzle this little thing.

Of course, there are not many of these things, but this is not something that Huang Fu Lin can embezzle alone, if they are scattered, these things are not too much.

"Yes......" Huang Fulin's forehead was covered with cold sweat, but he didn't dare not get up.

"It's only been four years since you took over the Ministry of Civil Affairs, and it's not all your problem, but now, you're a scholar, and there have been such big problems in your tenure, so you can't escape the blame, am I right?" Li Ke asked.

"Please punish Your Highness." Huangfu Lin took a deep breath and bent down not daring to raise his head.

"Just remember the punishment first, things always have to be investigated clearly, if in the next task, the Ministry of Civil Affairs can cooperate properly, I can treat this incident as if it didn't happen." Li Ke said lightly.

"Yes...... "What else can Huang Fu Lin do?" If so much corruption is really investigated, it will be a matter of falling to the ground, and he can only agree if he doesn't want to die.

"Well, when I go back this time, you'll have to help me investigate a few things." Li Ke said lightly.

"Your Highness, please speak."

"Check how many of the waiters in the Ministry of Civil Affairs, Langzhong, Wailang, and Principal have served for more than five years? Write it all down and give me a list. Li Ke said lightly, "In this way, I will record the tenure of all the personnel of the Ministry of Civil Affairs and the positions they previously held in the Ministry of Civil Affairs." ”

"Yes." Huangfu Lin took a deep breath, he didn't resist, he could only say whatever Li Ke said.

"Well, you don't know about it. You're good to go. Li Ke waved his hand.

Huang Fulin didn't say anything and left directly.

After Huangfulin left, Li Ke sighed, hey, I am not destined to be a completely rotten person, sitting in this position, I can't really mess up, so many people are watching.

Sick of it!

Thinking of this, Li Ke was angry when he saw Li Tai next to him, although he still had a blue nose and swollen face at this moment, but Li Ke directly reached out and slapped him on the head.

Li Tai: "??? ”

Li Tairen are stupid, isn't it the third brother, why are you hitting me if you have nothing to do? It's just that when he looked over and saw Li Ke's unkind eyes, Li Tai decisively confessed, and he lowered his head and looked directly at the music.

"What do you see, you understand these things for me first, as a prince, you can't even do math? It just so happens that I have a test paper here, and you did it. Li Ke took out a test paper directly from the drawer next to his desk and slapped it in front of Li Tai.

This test paper was left by Li Zhi before, and he is now being taught by the teacher transferred from Li Ke's side, and the test paper left before is just useless, so use it.

Li Tai: "......"

Looking at the numbers on the test paper, Li Tai's head was already starting to hurt.

But what Li Tai didn't know was that at this moment, there was another person in Chang'an City who was the same as him.

Wu Jue had the same expression as Li Tai at this time, and her scalp was numb as she looked at the numbers on the paper in front of her, as well as the things that needed to be calculated, which ...... Is it something that people see?

She came over to find Li Yan to go out shopping together, and it happened that Li Yan was studying, so Wu Yu took a curious look, and then saw this scene.
