Thin Orion looked at him disdainfully, "Can't you?" It was His Majesty who sent the women's army to help the people live a good life, not to mention wild boars, and I will give my life if you want it. ”

After saying that, he turned his head and went into the woods.

The bandits on this side are going on, and Li Xingchen personally went to the technical college to convene a meeting of all skilled craftsmen!

Many of the instructors of the technical college were transferred from the household department to teach the students.

Inside the conference room.

Everyone greeted Li Xingchen and sat around the round table of the conference to start the meeting.

"Ladies and gentlemen, I came here at this time to make an appointment with the Ministry of Industry to solve the problem of traffic light time.

Each person takes a breath for a long or short time, and it is biased to calculate the time of a traffic light by 60 breaths and 120 breaths. ”

Everyone nodded, it is true, young people breathe fast, old people breathe slowly, it is difficult to achieve a stable value.

It's not that the calculation is so good, but it will be blackmailed by someone who has a heart to seize the breathing hole.

For example, a bastard who deliberately slows down or accelerates his breathing when crossing the street, accuses the court of deceiving people, saying that he changed the red light without sixty breaths, which is a fraud, and the court will compensate him.

Li Xingchen, who is a time-traveler in later generations, has a deep understanding of the phenomenon of porcelain bumping, so after the meeting in the imperial study that day, he thought of this loophole. Similarly, Lin Datian also thought of it, so he convened this meeting to solve the problem of time.

"Ladies and gentlemen, if I set sixty breaths as one minute, how many minutes is an hour?"

Li Xingchen taught them step by step.

"Everyone knows that a day is twelve hours, so is one hundred and twenty minutes an hour?"

Everyone's brains were spinning, and it was.

It's just that minutes are a new term, and they haven't spared the bend for a while.

"Your Majesty is very true." The Ministry of Industry nodded.

Li Xingchen looked around at the crowd and saw that they almost understood, and continued: "I think that the twelve hours should be subdivided.

For example, how about changing the unit of the hour to hours, twelve hours during the day and twelve hours at night, for a total of twenty-four hours, which is equivalent to twelve hours as twenty-four hours? ”

Changing the noun and doubling the time is understandable to everyone, but they don't know what it means.

Li Xingchen said again: "Let's take the hour as a unit, an hour and sixty minutes, one minute is sixty breaths, and if we change the breath to a second, one minute is sixty seconds." ”

Li Xingchen said the 24-hour international time unit of the market outlook.

Twelve hours is good, but twenty-four hours is more reasonable to calculate day and night.

With the development of the times, there will be more and more night markets, and Li Xingchen also plans to lift the curfew on other streets except the main streets.

In this way, the 24-hour system is very necessary, but there are too many spies in the enemy country of Great Wei at present, and he has not planned to fully open the curfew, at least when the time is ripe.

An hour, sixty minutes, a minute and sixty seconds, for a while, everyone was shocked by the new time plan.

It has always been twelve hours, and everyone has been deeply ingrained in their hearts, and it is difficult to accept such a sudden change, and I am afraid that it will be even more difficult for the people to accept.

Li Xingchen smiled, "You can also understand that one hour is two hours. ”

He sat quietly, waiting for the people in the meeting to digest and accept.

Nowadays, there is no hour system in the world, so start with the Great Wei, and then the countries will gradually imitate the effect when they see it, and the countries will first learn from the Great Wei to see how the Great Wei does it.

Invisibly, the status of Dawei will be elevated and become an example in the hearts of people all over the world.

In the future, whether there is a war or not, Great Wei will be like a giant.

After a while, the Ministry of Industry Shangshu clenched his fists and said: "Your Majesty's words are time reforms, and the minister approves of them." ”

The change of twelve hours to twenty-four hours was agreed by some and disagreed by others, while others felt inappropriate and disagreed.

Because of conformism, it leads to sudden changes, which is difficult to accept.

But before they could open their mouths to refute, they heard the prime minister say, "The minister also thinks it's okay."

At present, we all rely on the watchman to remind you, and an hour is too long, resulting in many problems.

It is best to change the hour to the hour, which can shorten the reminder time. ”

Li Xingchen thought about it, it seems that there are many problems caused by the time index, no wonder later generations will plan the time as a 24-hour system.

"You are all the leaders of the technical college, there are talents from the Ministry of Engineering, and there are also skilled craftsmen from the people.

Speaking of this, Li Xingchen got up, "I have an idea that I hope the craftsmen can make, which is to create a round clock, which is divided into specifications from one to twelve.

Then design three hands, divided into hour hand, minute hand, second hand, the second hand rotates one time, the minute follows the rotation. After that, the minute turns in one circle, and then the hour hand turns, and so on. ”

As long as the clock is designed, there is no need to remind the time in the future.

Otherwise, when the weather is bad, I don't know the time at all. With clocks divided into 24 hours, you can know exactly when and where you are.

Everyone gasped, and some of the people who opposed it in front were not used to changing the time, and second, the time division was too much, too chaotic, and too mixed.

Originally, the watchman was to judge the time by looking at the sky and so on, so there was no point in subdividing time.

However, if it is really like what Li Xingchen said, with clocks, wouldn't they be able to observe the time accurately at all times?

It can be observed regardless of cloudy or rainy days, or even days without stars.

The Ministry of Industry Shangshu's face was full of shock.

"The appearance of the time instrument will enhance the people's concept of time, so as not to have all kinds of problems that delay the time, which is a great thing, a great achievement!" The official Shangshu exclaimed.

He was still thinking about how to refute the 24-hour system just now, but now he suddenly understood the importance, and immediately did not object, but was more concerned about whether it could be manufactured.

Li Xingchen smiled.

"The matter of making clocks and watches has to be handed over to the Ministry of Works, and I just put forward the ideas, and the Ministry of Industry will lead the skilled craftsmen."

At this moment, the Ministry of Industry Shangshu began to construct a blueprint in his mind, and every time he rotated, he had to drive another hour hand to rotate, so precise, it was not easy to get it.

The Ministry of Industry Shangshu looked embarrassed, "Your Majesty does you have a design drawing?" Otherwise, it will be too difficult to create plainly.

It is best to draw a rough design drawing first, make a first version, and then debug and transform it, as was the case with previous bicycles. ”

"Come here." Li Xingchen stepped aside and beckoned to the Ministry of Works.
