Li Shimin's will: Li Zhi, the throne belongs to your brother

Are there more craftsmen in this way? "

Before Li Shimin could answer, Li Jing, Shangshu of the Ministry of War, answered with a smile.

"Skilled craftsmen have a ruler in their hearts, and the production will never be the slightest bit off.

Only novices will carry a ruler and rope with them for measuring.

However, I don't know the specifics of what His Highness said. "

Of course Li Tai knows about the ruler, but what he wants to talk about is not this, but the problem of the extended system through the problem of the ruler.

Before the Tang Dynasty, there were non-decimal monetary units such as baht and lei, which were later changed to money, cents, and centimeters.

But many have not been changed, such as the two-size system, one foot and two inches is a large ruler, three small buckets are a big bucket, three small taels are a large tael, and 16 taels is a catty.

Li Tai nodded.

"What this king is talking about is not about tools, but the complicated and chaotic dual system of size and size. This king actually wants to change the weight and measure, and every tenth is equal to one."

"This..." Li Jing thought for a while, then turned to Li Shimin for help.

"This has been used like this since ancient times, and I really think there is nothing wrong with it." Li Shimin was also very puzzled.

"Father, my son has a question. The mutton is fifty cents a catty. If only the last bit of mutton is cut up, and the mutton weighs two big two two small taels per catty, how much should such a small amount of meat be sold for?"

ah... this...

Baiguan began to think.

It is really difficult to mix hexadecimal with ternary, and more importantly, it is inexhaustible.

It is quite troublesome to use, and it takes a long time to do mental calculations, which is inconvenient and difficult to use, it is too confusing.

After waiting for a few seconds, Li Tai opened his mouth and said, "The rudimentary I mean is not the tools, but the weights and measures.

One catty is 16 taels, and three small taels are one big tael.

It can be said to be extremely difficult to calculate. If it is the same as coins, it will be changed to every ten.

Then you can use the superior multiplication song, and everyone can know numbers, and if it is more complicated, you can use the abacus. "

"This is indeed the truth." Li Shimin calculated in his mind for a long time, and was interrupted by Li Tai when he had a clue.

Multiplication songs existed in the Spring and Autumn and Warring States periods, and abacus existed in the Eastern Han Dynasty. There is even a method of drawing horizontal lines on a sand table, but they are only applicable to decimal systems.

In addition to the hexadecimal system and the ternary system, there are more base systems, such as half a step is called a foot, seven or eight feet is a Ren, eight feet is a find, and thirty miles is a house.

This is pretty disgusting.

"This matter is still to be discussed, but this decimal system is indeed easy to use."

"Thank you, father." After finishing speaking, Li Tai raised his head and drank the bottle of wine.

"Yeah." Li Shimin didn't pay much attention to this question, although he didn't understand it, he agreed along with Li Tai.

"Another reward, one thousand acres of land, one hundred cattle and sheep each..."

After all, Li Tai is a prince, and only farmers, cattle and sheep are enshrined, and his reputation is basically at its peak.

"Everyone, have a drink!"

After drinking a glass of wine, Li Shimin took the lead in moving his chopsticks.

The chopsticks can only be moved by people in order of official position.

"There are food and wine, why don't your majesty let people dance to a song?"

Cheng Yaojin stepped forward to liven up the atmosphere: "It's the so-called beauty that can be eaten!"

"You old Cheng." Li Shimin shook his head, and with a look, the people in the Ministry of Rites immediately understood.

Not long after, a group of kabuki came out and danced in the hall.

The civil and military officials started the bragging and chatting scene.

"Your Highness, I don't believe you when you say that you are looking at a girl named Rouyi with beautiful nails."

Cheng Yaojin stared at Li Tai with his eyes wide open, holding his wine glass.

"Yes, yes! I don't believe it!" Yu Chigong with a big black face also came over.

"I don't believe it either." Qin Qiong also came over.

"Forget it if you don't believe it..." Li Tai couldn't explain it either.

"Then, old Cheng, I believe it." Cheng Yaojin rolled his eyes, revealing an instant understanding.

"But can your highness tell me, which family's woman are you looking at? How beautiful is Rouyi?? Hehehe~"

Cheng Yaojin had an expression of coming.

Before Li Tai could speak, Yu Chigong asked, "Ah, could it be a woman from a brothel?"

"Your Highness, you have to pay attention to your identity!" After finishing speaking, Cheng Yaojin looked regretful, as if he believed that Li Tai had already been there.

There are more than 50 people, and Li Tai is very speechless like a child.

"Come to introduce to you, my family's unfilial son Cheng Chumo, you will go in the future and let him show you, this way he~ familiar!"

"..." Li Tai was puzzled, what the hell is this.

Li Tai quickly explained: "This king is a decent person, so he won't go."

"Hiss, I'm also a decent person, and I haven't been there before." Cheng Chumo gave a look that any man could understand.

who am I?

where am I?

Li Tai felt that the whole person was not well, and suddenly there were several younger brothers who helped the brothel to let the wind out.

Unlike everyone else, Zhu Suiliang took out a pen and paper from his sleeve and began to record slowly.

In the 14th year of Zhenguan, after the autumn harvest, the frontier army changed horses, and all the officials discussed, but the ministers had no solution.

The king of Wei threatened to put shoes on the horse, and all the officials laughed at it.

The king of Wei said angrily that empty talk on paper is not enough to be believed, and words are not as good as deeds.

The sage agreed with his reasoning, and all the officials went to the imperial horse prison.

The king of Wei bowed himself, printed the hoof with paper, and craftsmen made it, which was shaped like a hook. He burned the hoof with heat, and then put iron nails through it.

Everyone was shocked, the Holy Majesty drove in person, and seeing that the horse's hoof was not damaged at all, they were overjoyed and held a banquet.

After thinking about it, he still didn't record the matter of Li Tai riding a horse. As for changing the weights and measures, it still needs to be discussed.

Chapter 15 Horsemanship

That night, the same scene was staged in the homes of countless civil servants and generals.

At this time, the six arts of a gentleman are not lost, even civil servants can ride horses and wear swords.

So they were half drunk, found the blacksmith, picked up the iron bar and started to strike iron amidst the dissuasion of their family members.

Yu Chigong even picked up the long-lost hammer under the persuasion of his wife, son and daughter.

"Quick, light a fire for me, I want to put shoes on the horse!!"

Yu Chigong was born as a blacksmith and possessed brute strength, but at this time he was half drunk and half awake.

Yuchi Gong had two wives, Mrs. Black and White.

In the early years, she married her sister Su Bin, but Su Bin died at the age of 25.

Before he died, thinking that his sister was alone and helpless, Su Bin entrusted his sister to Yu Chigong.

"Ah?" Su's face was bewildered, and she looked at Yuchi Baolin in confusion.

"Mother, you go in first and let the son come." Yuchi Baolin was also half drunk and half awake and started to light the fire.

Soon, the fire rose, and the father and son hit the iron with a hammer without a hammer.

As time passed, Jiu Jin gradually sobered up, and this iron was more energetic.

Finally, the four horseshoes were finished.

"Quick, bring a horse!!" Yu Chigong said.

"Yes, father!" Yuchi Baolin ran to the stable with a look of excitement.

The horse standing vigilantly neighed at this moment, which would wake up the rest of the sleeping horses.

"It's just you standing still, it's just you, come and follow me obediently, I'll put your shoes on for you."

While muttering, Yuchi Baolin took the reins.

"Father, hurry up and see if the horse's shoe fits." Yuchi Baolin said to Yuchi Gong excitedly.

Yu Chigong began to measure on the horseshoe with the horseshoe.

This one is a bit worse, this one is a little bit worse, two of the four horseshoes are a little bit worse.

At this moment, Yu Chigong somewhat understood why the horseshoe print was printed on paper.

"Go and trim the horse's hooves first, I'm hammering twice." Yu Chigong gestured in his hands.

"Yes, father." After saying that, Yuchi Baolin began to repair the horse with the dagger.

Soon, the horseshoe was repaired, and Yu Chigong asked, "Is father alright?"

"Okay, okay!!" Yu Chigong held the horseshoe and nails excitedly.

"Finally joined hands." Yu Chigong was very pleased to see the horseshoe, learned Li Tai's method, and quickly nailed the horseshoe.

"Hey, now my old black has a horse wearing shoes." Yu Chigong said with a happy face, "I'm going to find Lao Cheng to show off."

As soon as he got on the horse, he was about to go out.

"Husband, where are you going?" Su Shi was awakened when he heard the movement of the horse, and asked hastily.

"Look, madam, I've put shoes on the horse, and I'm going to Lao Cheng to show him."

Surprised on Su's face, she leaned closer to see clearly through the light of the fire, she thought inconceivably in her heart, and exclaimed: "It's really a god."

"This is today in the court, the king of Wei proposed to put shoes on the horse, and I got these iron shoes.

These millions of iron cavalry can flatten Goguryeo, no problem!

I want to show off to Lao Cheng. "

"But, my husband...it's not yet dawn!!" Su said, pointing to the moon in the sky.

"It's not yet dawn..." Yu Chigong repeated in a daze, looked up at the bright moon...

Sure enough, the moon was high and the stars were shining.

"Eh..." Yu Chigong hesitated, and thought for a while.

It's a curfew now, it would be fine if I went to find Lao Cheng by myself in the past.

But not long after the prince rebelled, the guards in Chang'an City were strictly guarded, so it's better not to arouse Li Shimin's suspicion...

Thinking of this, Yu Chigong dismissed the idea of ​​violating the curfew.

"Oh, that's all. Tomorrow, I, Old Hei, will have a duel with Old Cheng."

At the same time, all the officials have more or less given up.

After all, only a few of the officials know how to forge iron, and more people find a blacksmith to do it.

When they finished, it was already late at night, and the idea of ​​riding a horse to celebrate the carnival had to be given up.

Except for Li Shimin.

Li Shimin rode the horse around and around, and the horseshoe did not come off at all.

He personally felt the benefits of horseshoes, claw mud, gravel beaches, and even ice and snow.

With this horseshoe, there is no need to worry about the wear and tear of the horseshoe on this terrain.

"A fetish, it really is a fetish!!" Li Shimin exclaimed in admiration.

Thinking of this, Li Shimin couldn't help but think of the scene where Li Tai was taken back by Cheng Chumo and Yuchi Baolin.

It was really embarrassing, I didn't expect this kid to be so overwhelmed by alcohol, he fell down after only three or five bottles.
