His Majesty Li Er finally compromised, and after giving Li Chengqian a handwritten message, he completely drove out of the office, and secretly sighed in his heart that this little bastard was becoming more and more shameless.

"Young Master, this is Your Majesty's handwritten message, please take it away." After returning to the 'Lanruo Temple', Old Man Xiao really didn't leave, and Li Chengqian naturally wouldn't expose Lao Xiao's thoughts, but just respectfully presented Li's second-hand edict and found a place to sit down.

"Your Majesty agreed?" Deep down, Lao Xiao has always believed that there is no point in redefining weights and measures. But for those involved in the decision-making, it is very meaningful.

"My lord, my father's edict is very clear." Li Chengqian pointed to the oracle that Old Man Xiao was holding in his hand and said with a smile.

After reading the edict brought back by Li Chengqian again, and studying it repeatedly, Lao Xiao thought it was true, and he thought that this kid would not do the stupid thing of forging the edict.

The edict was true, Lao Xiao was naturally relieved, and he also respectfully put away the edict, and then continued: "Your Highness, I wonder if Your Majesty has stipulated a standard for determining the unit of measurement?" ”

"Uh~, this one doesn't." Li Chengqian pondered for a while before he understood what Lao Xiao was talking about.

Any unit has a benchmark, for example, the weight unit of the Tang Dynasty is based on two, ten Kaiyuan Tongbao issued during the period of Li Yuan Wude is one tael, and a thousand pieces are six catties and four taels.

What a fucking algorithm to know how much a pound is? Go back and count slowly, use the counting method of one two or three to calculate, and make sure that you want to die.

"But the old man will find a time to ask my father about it." Without waiting for Lao Xiao to continue to ask, Li Chengqian continued his previous words and said.

It's just a 'my father', no matter how you listen to it, you're oppressing people with power.

One afternoon, Lao Xiao Tou basically lived a life of disobedience, and re-determining weights and measures is by no means a casual standard, which involves all aspects of the problem.

For example, how do you convert it to the previous standards? How to get those who are used to the old standards to accept? These are all questions.

Anyway, as far as the author is concerned, if a person suddenly comes and says that the decimal system has been changed to the nine-base system, the author will never accept it, first, it is troublesome to calculate, and second, it is too awkward.

However, these are not problems for Li Chengqian, he only has to come up with ideas, whether he can complete it, and how it is completed has nothing to do with him.

It's done, and it's been passed down through the ages; If you don't get it ......, then you don't need to talk about it.

AS FOR THE QUESTION OF WHETHER THE NEW WEIGHTS AND MEASURES CAN REALLY BE PASSED DOWN TO FUTURE GENERATIONS, BROTHERS, THINK ABOUT WINDOWS, THINK ABOUT APPLE, THESE ARE ALL STANDARDS, DOES ANYONE ELSE AND OLD JOE NOT KNOW? AS LONG AS YOU USE APPLE FOR A DAY, YOU WILL THINK OF OLD JOE, RIGHT?

Of course, if it is not accepted after the redetermination, it will not be Li Chengqian's problem, and if the opportunity is given, what can be done if he can't grasp it.

Comrade Xiao Li was worried that the old man would not find his way home in his current state, and if he got lost, he would be in a lot of trouble.

The next day, Comrade Xiao Li heard Lao Li's dictation as he wished, led by Xiao Yu, with the cooperation of the eldest grandson Wuji, Fang, Du and others, to redefine the weights and measures.

finally sent this old guy away, and Li Chengqian was in a good mood.

Moreover, if the old man behaves better and cooperates with all aspects in the future, Li Chengqian also does not mind talking to him about the conversion between weight and capacity, the relationship between mass and density, and other issues.

It doesn't matter whether the old man likes to listen to it or not, whether he wants to listen to it or not, the important thing is that Li Chengqian can find the pleasure of tossing people here.

During this time......, Li Chengqian listened to it no less than twenty times, so he planned to let the old man 'learn from the past' if he had the opportunity.

In short, today is a good day, the young master of the prince has something to do, and he will not come to trouble him again, Wu Chen and the 'bald king', who have lost weight three times, have returned, and the days can finally return to normal.

With Lao Wu and Lao Wang, who still had some fluttering legs, Li Chengqian decided to go to see Su Dingfang, and he didn't know if Lao Su was used to staying here.

"Su Lie has seen the prince." Lao Su, who is already the deputy leader, has a straight body, stands like a mountain, and his voice is like a bell, a typical image of a tough guy in the army.

"Excuse me, Lao Su, how are you doing these days? Habitual or not? Walking to Lao Su's side, looking at this strong man who was several heads taller than himself, Li Chengqian couldn't help but sigh while asking, fortunately, there are still people like Lao Su in the army, if they all have the same virtue as Cheng Fairy, this Datang is afraid that he will finish his calf.

"It's good, my colleagues are also good, and I take good care of Su." Lao Su followed Li Chengqian's side and walked to the office, talking as he walked, with a hint of cheerfulness in his tone that he hadn't had before.

Su Lie, who is now Chinese New Year's Eve one year old, followed his father to fight in the killing field at the age of fifteen, and it was not until the sixth year of Wude that Liu Heimin hung up before returning to his hometown to live in seclusion.

After more than ten years of fighting in his life, in the end he could only be a farmer, buried in the countryside, no matter how indifferent to fame and fortune, he was a little unwilling in his heart.

So when Su Gan Chengji found him and showed the prince's seal, Lao Su's heart couldn't settle down, and after thinking about it for a few days, he said goodbye to his family and followed the anti-bone boy into Chang'an.

"Lao Su, have you ever thought about bringing your family here?" Entering the office of Su Dingfang, Li Chengqian casually found a chair and jumped on it, and asked in a harmonious voice.

"Let's wait until it's settled." Lao Su's face was embarrassed, he must have just arrived in Chang'an, and he still lived in the barracks, wouldn't he have to sleep on the street if he brought his family here.

"Lao Su, you are not a real person, if you have any difficulties, just say, although my prince is not very capable, it is still possible to solve some difficulties for his subordinates." Looking at the embarrassed old Su, Li Chengqian pouted and said.

"I'm afraid General Su doesn't have a place to live, right?" Wu Chen, who was connected to Lao Su with the same illness, spoke at this time.

As soon as he was reminded by Wu Chen's words, Li Chengqian suddenly slapped his head hard, how could he forget about it.

Lao Xue, Lao Xi, Wu Chen, and the 'Bald King' are all bachelors who come into contact with Li Chengqian, and Li Chengqian doesn't care about living in the barracks or living in the Qinglou at all.

"Your Highness, it's okay, there is a lot of money in the army, and after a while, I have saved enough money to buy a yard, and then it's not too late to pick up my family." A well-known man, who has been fighting horses for more than ten years in his life, has not saved the money for a property.

"Lao Su, do you know how many officials you are now?"

Li Chengqian suddenly changed the topic, and Su Dingfang also lamented in his heart, it seemed that he still overestimated his status in the eyes of the prince.

"Deputy rate, from the fourth grade." Li Chengqian stretched out four fingers, compared them fiercely in front of Su Lie, and then continued: "For a house, it is like this. Okay, don't save money, I'll figure out a way about the house, you just have to write a letter to your family and let them come to Chang'an. ”
