In the past two years, the powerful and powerful have often occupied land, that is, check Jingyang. If you look at other places, you may have some twists and turns. The land problem in the Tang Dynasty is a tight rope.

Li Shimin looked down at the formula on the table and was frowning. Of course, he wanted to investigate the fields in the world.

But since the former Sui Dynasty, there have always been cases of powerful people occupying land.

Although the matter in the court is still clear and clear now, the problem is still in front of us.

This is a lesion left by all dynasties.

If you want to remove this lesion, you need to take strong medicine.

Li Shimin sighed and said, "Fang Xuanling, do you think I should do it?"

Fang Xuanling whispered: "Your Majesty has been in the Tang Dynasty for less than a hundred years, and I think it's not the time yet."

Li Shimin smiled bitterly, and somehow an idea suddenly flashed through his mind. Li Zheng must have a solution.

Sighing tiredly, Li Shimin whispered: "It's getting late, so you can rest early."

Fang Xuanling bowed and said, "I will say goodbye."

Sitting alone in the Ganlu Hall, Li Shimin looked at the empty night outside the hall and was silent.

As soon as the day dawned, the Ministry of Revenue's investigation of land began to take place tensely again.

With the formula given by Li Zhi, the speed of checking the land account books was several times faster.

A number of officials from the Ministry of Revenue were even able to learn from this formula, multiply and divide each other and half a year's land account book was completed in just a few hours. Wei Zheng looked at the speed in front of him with relief and nodded with relief.

Beside the fields in Jingyang, Li Zhi also led several officials from the Ministry of Revenue to start measuring the fields.

Li Zhi took out a coil of coils and said, "The ten colors of this coil are ten feet in cycles, so you don't have to use such a short measuring ruler to measure one by one."

The official from the Ministry of Revenue took the coil and said, "Is this thing accurate?"

Li Zhi said: "The error will not be too big."

To be cautious, the Ministry of Revenue officials first measured the fields.

As Li Zhi said, the wires of this coil have ten colors, and the length of each color is one zhang.

After confirming that it was correct, the officials of the Ministry of Revenue began to measure with this coil.

Tie one end of the coil to a pile, then pull the wire backwards, pull it to the other end of the field and then use another wooden pile to fix it.

The lines are straight and parallel to the ridge of the field.

Just count the colors above to get the width of the field.

Most of the fields in Jingyang are paddy fields.

It's also convenient to measure.

It depends on whether the officials of the Ministry of Revenue calculate the area of ​​the land or use the heavy subtraction and addition method.

Li Zhi shook his head and said, "You calculate this way, when will you calculate it? Has our Ministry of Revenue always used such a stupid method to calculate it?"

These officials from the Ministry of Revenue looked at each other and smiled bitterly and didn't know how to answer. In fact, the Ministry of Revenue has always used this method to calculate land.

"I would also like to ask His Highness the King of Jin for advice."

Li Zhi sighed and said, "I don't know how you usually do things for your father."

Listening to Li Zhi's criticism, these officials from the Ministry of Revenue were unhappy. How old is His Highness King of Jin?

He is only fourteen years old this year and has not grown up.

Li Zhi wrote the formula and said: "In fact, there is a simpler method. First of all, the length and width of the field must be clear. Multiplying the two is the flat area."

Square area?

A group of officials from the Ministry of Revenue were confused again.

Li Zhi also said: "There are many words about multiplications and multiplying them is called power. In fact, the predecessors have given us the answer to the formula for area. Your officials from the Ministry of Revenue do not know this."

"We are so careless that our highness, let His Highness King Jin laugh."

Li Zhi continued: "After we calculate the area, we will find the number of land acres. According to the number of land acres in your Ministry of Revenue, we should go in three and three, square to three, and then divide by one acre of value, that is, the number of land acres. According to fifteen acres of land, the total number of land we measured is two hectares."

After Li Zhi finished speaking, several officials from the Ministry of Revenue looked at the formula without turning their eyes and remained silent.

The officials of the Ministry of Revenue still have some understanding of the number of methods.

On weekdays, I have to calculate taxes, money and salary, and I have a lot of numerical techniques.

I was stunned for a moment when I saw Li Zhi's formula. The algorithms that are so complicated in daily life have become much simpler after Li Zheng's set of formulas.

Look at yourself and then Li Zheng, and I feel like I have lived in vain for half my life.

Li Zhi said: "If you have any questions, come to the academy to find me, or find other senior children. I think such a simple question should not be difficult for you."

The officials of the Ministry of Revenue still smiled awkwardly.

Wei Zheng, who was resting at noon, came to the horse circle and saw Li Zheng sitting leisurely under the shade of the tree while drinking tea.

Seeing Wei Zheng coming, Li Zheng said, "Is Duke Zheng finished his work?"

Wei Zheng sat down and said, "I checked your road construction matter when I first found out, but I didn't find any clues."

Li Zheng said: "Speaking of the matter of Zheng Guogong's investigation of our road construction is actually an advertising effect for us. I hope Zheng Guogong will continue to investigate."

Wei Zheng said, "You think I helped you instead."

Pour a cup of tea for Wei Zheng, Li Zheng smiled and said, "I don't keep much good tea before the Ming Dynasty. Is the Duke of Zheng a taste?"

Wei Zheng picked up the teacup and took a sip of hot tea, and still looked at Li Zheng, "Why is it wrong for me to hear?"

Li Zheng said: "Duke Zheng, do you know?

What is your reputation outside?"

Wei Zheng sneered: "I never care about my reputation."

Li Zheng said: "It doesn't matter if you don't care about your reputation, but your reputation outside is a loyal minister who is honest and upright, dares to speak out directly, and an old stubborn man who doesn't make any progress."

After hearing these words, Wei Zheng's brows leaped.

Li Zheng said again: "I want to thank Duke Zheng, the counties we built on the road are all our obstacles, but Duke Zheng could not find any problems, but instead made our road construction faster and smoother."

I was in a good mood, but because of the land inspection, I would like to thank Li Zheng for his help.

Now Wei Zheng has no feeling of thanking him at all.

Li Zheng took a sip of hot tea and said: "The weather is very good today, right? Duke Zheng."

Wei Zheng looked at Li Zheng and said, "Are you using me?"

Li Zheng sighed: "The Duke of Zheng is such a bad word."

Wei Zheng said coldly: "Why isn't it?"

Li Zheng shook his head and sighed: "First of all, Duke Zheng of Zheng also understands that building roads is beneficial to the country and the people, right?"

After thinking for a while, Wei Zheng said, "I think there are pros and cons. To conquer the people's strength and to build a large scale of construction requires extreme caution. The Tang Dynasty is the time to rest and recuperate. It is indeed a bit inappropriate for you to build a large scale of construction at this time."
