Li Yuan sat high on the dragon chair, and the hundred officials knelt down.

A man dressed as a military general is reporting to work.

"Since the army of Jieli Khan attacked Lingzhou in June, it has successively broken through the Xiangzhou lands, and the acting county governor was defeated in Xincheng; The Turkic army was extremely fierce, relying only on the right guard general Zhang Jin to garrison Shiling, and Li Daliang led the army to defend Dagu; I'm afraid that it will be difficult to stop the Turkic army; His Majesty asked His Majesty to once again send the King of Qin to lead the generals of the Tiance Mansion to garrison troops in Puzhou to prepare for the southern invasion of the Turks. ”

After speaking, the military general stood still and waited for the emperor's reply, but Li Yuan was thinking about the future of the Qin king from his throne.

Speaking of which, Li Yuan has never been a wise and decisive person, everyone else is the father who created the foundation and let the sons inherit it; This Li Yuan is good, the great rivers and mountains are basically fought down by several sons, even the initial army in Taiyuan against the Sui, it was the son who persuaded and persuaded him, and analyzed the pros and cons for him several times, so that he made up his mind, and then there was Datang. In short, he is a father who enjoys the blessings of his son, and in the end, he enjoys his success and becomes the emperor.

But although the Central Plains is large, there can only be one throne, the crown prince and the king of Qin are both excellent heirs to the throne, and they also have their own forces; As the man of God said, when two great powers fight, one will be wounded. In the past, when the gods did not break this relationship, in the face of the open and secret struggle between the prince and the king of Qin, Li Yuan could only pretend to be deaf and dumb as if he didn't see it, the palms and backs of his hands were full of meat, and his two sons had made great contributions to the Tang Dynasty; It's hard to clean up who gets down.

Now that the gods have bloodily dissected the outcome of the struggle between the crown prince and the king of Qin, if Li Yuan doesn't want to see his sons kill each other, he has to face up to the matter of the heir. Fortunately, although the man of God dug a pit to trap the father and son, he also gave a solution; Go to the outer land and build a Datang again.

Since the god man said, there are a large number of borderless lands outside of my Tang Dynasty, if you can't pass the throne to the king of Qin, then let the king of Qin go to the borderless land to start a new dynasty, this is not only a reward for the king of Qin, but also a compensation for his father to his son; At least half of this Tang Dynasty was fought down by the second son.

It's just that since he disappeared yesterday, the god man has not appeared for a long time, and without his reassurance, Li Yuan can't make up his mind whether to send the King of Qin out to defend against the Turks.

Let's send it out, in case the god-man brings a map and wants to assign the second son a borderless land, but the second son is not there, will it annoy the god-man. If you don't go, the Turkic barbarians have already reached Xiangzhou, and without the strong army of the Qin Palace, the situation in the north will only be corroded.

After hesitating, Li Yuan still decided to put his hope on the gods, and let the King of Qin wait for the result, according to the meaning of the national teacher, one day in heaven and one year on earth; The god man will turn around in two or three days at most, and it has been more than two months since the Turkic invasion of the south, and he doesn't care if he is so late, right?

So he said: "The king of Qin has other important matters for the time being, and he must not leave Chang'an to go on the expedition; To resist the Turks, for the time being, let Li Jing, the governor of Anzhou, send troops from Luzhou Road; The general manager of the march is stationed in Tun Taihang Mountain. ”

When talking about Li Jing and Ren Huan, the two stood up from their respective seats; "The last general commands!"

When he had received his order, he went back and sat down on his knees.

The other ministers of civil and military affairs did not know about the confidential god-man incident, so when they heard that Li Yuan still left King Qin by his side at such a critical moment in the national war, they were very surprised, and they all made eye contact; Did the emperor have something in mind?

The people who had no answer looked at King Qin, who was the head of the ministers. But the King of Qin, who was the party concerned, sat in the position of prime minister, bowed his head and didn't know what he was thinking, and didn't touch the eyes of his courtiers; Looking at the crown prince opposite him, he was actually the same as King Qin, waiting for the emperor's order with low eyebrows and ears.

On the contrary, the King of Qi, who is not usually particularly valued, sat in his place and looked back at everyone from time to time, and used one word to describe it: Eagle Gu; Like an eagle looking for prey, staring at a minister from time to time; It seems that he is looking for someone among the ministers.

It's not right, it's weird!

No matter how strange the atmosphere is, the court discussion will continue. At this time, another Wenchen stood up and said: "Your Majesty, from the beginning of the Sui turmoil to my Tang Dynasty, the weights and measures of the state capitals have not been verified for 20 years, and many of the state capitals' weighing instruments have been damaged due to war; For the livelihood of the Tang people, Taifu Temple asked for an order to check the weight and measures of each state; Re-establish the unified standard ...... in the world"

When the minister was still talking about the importance of unifying the world's weights and measures, he heard the exclamation of his colleagues around him: "Wow! When he subconsciously looked up, he saw a simple white door suddenly appear next to Emperor Li Yuan's dragon chair. A strangely dressed short-haired monk walked out of the door in full view of everyone.

Some people in the main hall had seen such a scene on the tower of Xuanwu Gate with the emperor and others yesterday, but more people saw it for the first time; Although some of them had heard of the Inhuman incident, when they actually saw it, the shock was far greater than hearsay.

A military general reacted, Huo Ran stood up and shouted: "Come on, catch the assassin!" ”

Then Li Yuan also saw the door that suddenly appeared next to him, and immediately jumped up from the dragon chair happily and said loudly: "The god man is here!" The man of God is coming! "This man of God really came without a thought.

As soon as the forbidden army guarding outside the hall heard that there were assassins in the main hall, they immediately rushed in a large area.

As soon as he entered the main hall, Ye Jinyu was a little dazed, he didn't expect that there would be so many people here, and the soldiers were still pouring in from all over the doors; With the clatter of armor, the hall was suddenly filled with people.

However, in the face of these people, Ye Jinyu was no longer so afraid, because he knew that he was by Li Yuan's side, and Li Yuan would inevitably protect himself.

Sure enough, after Li Yuan saw that the god man was a little frightened, he hurriedly waved his hand and said, "This god man is the lucky star of my Tang Dynasty, and the generals cannot make a mistake; Stand down! ”

The emperor's words were like hitting the valve of a bathtub, and there was another clattering sound of armor, and the soldiers of the forbidden army retreated like a tide. The hall was empty again.

Looking at the emperor who relieved him, Ye Jinyu didn't know how to greet him for a while; Because he didn't know what he was going to call the emperor. Called Li Yuan? People are so old, even if he is not an emperor, just an ordinary old man, it is not polite to call him by his first name. Called Your Majesty? Or is it called the Tang Emperor? The Son of Heaven? As a modern youth born in the post-90s and growing up in the new century, this name gives people a strange feeling.

Forget it, do as the locals do. Ye Jinyu learned to bow his hand to Li Yuan slightly, and said, "I have seen His Majesty the Emperor." Then he looked at the stunned people in the main hall, and asked very suspiciously: "Your Majesty the Emperor, who are you?" ”

"Oh!" The emperor glanced at the ministers, and finally looked at the minister who was still holding the wat board and wanted to report, and said casually: "This morning, the matter of weights and measures is being discussed. ”

"Weights and measures." Ye Jinyu nodded to show that he understood, and it was said in the history book that Qin Shi Huang had the same book and the same track, and unified weights and measures; I didn't expect the Tang Dynasty to do this.

Li Yuan would be very happy, seeing Ye Jinyu nodding, he asked, "Do the gods also understand this?" ”

"I understand!" The person who asked asked casually, and the person who answered also answered casually, but when Ye Jinyu casually replied to Li Yuan, he suddenly thought that he would have to deal with the time and space of Datang for a long time in the future, or take this opportunity to understand the measurement method of this time and space; Of course, it would be better if we could unify the weights and measures of the two planes.

So he asked:

"Your Majesty, I don't know what the situation of Datang's measuring tools is?"

This question stopped the emperor, as the emperor of the Tang Dynasty, he has a lot of opportunities, how can he have time to care about the small people. couldn't answer the question of the god, so he had to look at the civil official of Taifu Temple who was still standing at the foot of the stairs and ask him for help.

The civil official was interested, and when he saw this, he immediately answered: "Your Majesty, in terms of weights and measures, I follow the Sui system in the Tang Dynasty: the length is based on the medium and large of the northern millet millet, and the length is one centimeter, ten inches is one inch, ten inches is one foot, one foot and two inches are large feet, and ten feet is zhang." The volume is also based on the medium and large millet of the millet, which allows 1,200 millet to be the 龠, two to be a combination, ten to be a liter, ten liters to be a bucket, three buckets to be a large bucket, and ten buckets to be a hu. The weight is also based on the medium size of the millet millet shall prevail, the weight of one hundred millet is one baht, twenty-four baht is one tael, three taels is a large tael, and sixteen taels is one catty. ”

This official is quite conscientious about his own work, and when it comes to the contents, it is reasonable; But Ye Jinyu was confused, he had heard at most five of the first ten measure words here; What can be used in life is even more crooked.

But he roughly understood the meaning, and the official's meaning was that the weights and measures of the Tang Dynasty were basically based on a crop called millet millet; Taking the unit of length as an example, a medium-sized millet is the standard, a millet is one point, ten is an inch, and ten inches is a foot.

Similarly, the volume unit is also based on this crop called millet millet, and it is still the same size as the selected millet millet with one thousand two hundred millet as one millet What is this millet Ye Jinyu didn't understand for the time being, but he understood that twenty calf is one liter, and the measure word liter Ye Jinyu used it at home when he was a child.

The weight is also based on the medium-sized millet standard, one hundred millet is one baht, twenty-four baht one tael, sixteen taels and one catty, that is, half a catty and eight taels.

From a modern point of view, this is an extremely complex and non-standard weights and measures, Ye Jinyu couldn't help but shake his head.

The emperor looked at Ye Jinyu and shook his head, and asked, "Could it be that the god man does not recognize my Tang Dynasty's measurement system?" ”

Ye Jinyu said in his heart, how can I tell you, could it be that the Emperor of the Tang Dynasty, your weighing instruments are not scientific! You have set the standard of all scales by setting the medium size of the millet as the standard for all scales, so how do you measure this medium size? If those landlords, merchants, and officials use small millet to fill large millet with small millet, will it cause damage to the interests of the common people? Their interests are damaged, and the final responsibility will be blamed on your political axe, one day you won't be able to get mixed up, and you will be unlucky in the end! Of course, the reasons for this rebellion are varied, and it is certainly unscientific to rely on the scales, but trying to maintain social fairness and justice is conducive to the establishment of a harmonious society.

Thinking in his heart, he said: "It's a little too unscientific!" It's not good. ”

Li Yuan didn't understand what science and unscience were, but he could understand that Ye Jinyu couldn't look down on Datang's weighing standards, so he asked, "What does that mean by gods?" ”

Ye Jinyu said with confidence: "Your Majesty, it is up to me to assist the officials of the Tang Dynasty to complete the new weights and measures." ”
