    "Old Liu~Old Liu!"

    Here, as soon as He Yun left Liu Jin's study, the voice of Prince Zhu Houzhao came over. He looked very excited, as if something happy had happened.

    I saw Zhu Houzhao walking over excitedly with something the size of a face plate in his hand, and when he was approaching Liu Jin's study, he covered it again.

    "Your Highness~"

    Looking at Zhu Houzhao's appearance, Liu Jin suddenly laughed.

    After all, he was still a child. Although Zhu Houzhao in history is now an emperor, Emperor Hongzhi cured his intestinal carbuncle and his health is getting better and better. It is estimated that Zhu Houzhao may have to be a prince for several more decades. Of course, he is not interested in being an emperor.  He has no interest in it. He would probably be happy to be the prince for the rest of his life.

    "Old Liu, guess what is in my hand?"

    Zhu Houzhao asked slightly mysteriously while carrying the thing in his hand on Liu Jin's back, blocking it with his own clothes.

    Liu Jin looked at this thing as big as a washbasin carefully, thought for a moment and said, "What kind of treasure is this, I can't guess."

    "Haha, even you can't guess it, that's right."

    Zhu Houzhao immediately became happy, and then he opened the blocking clothes, revealing the cold mechanical shell, and could see some clockwork-like devices next to it.

    Then Zhu Houzhao turned it over, facing Liu Jin, and then put the things on Liu Jin's desk.

    "This, is this a clock?"

    Liu Jin couldn't help but get excited when he saw something. He looked very excited when he looked at the things on the desk, and then looked at them carefully.

    You can be sure that it is indeed a clock.

    It is similar to the clocks of later generations. It is a circle with several hands and corresponding scales. One pointer is constantly rotating. Where the remaining two pointers are pointing, you can clearly see the inscriptions on it.  word.

    "Not yet?"

    Liu Jin looked at the words on it, and then looked outside. It should be almost no time, which is around two o'clock in the afternoon.

    "Haha, how is it?"

    Zhu Houzhao looked at Liu Jin's surprised look, and immediately became even happier. He said very proudly: "Hey, in order to make this clock, I specially studied with several craftsmen from Europe."

    "Don't tell me, the Europeans are indeed better than us at making clocks. They were able to make mechanical clocks more than a hundred years ago."

    "Referring to their principles of making mechanical clocks, I improved them and created the current clock."

    "Why do we still use twelve o'clock in calculating this time?"

    Liu Jin nodded slightly, looked at the words on it carefully and said.

    "The Europeans divide the day into 24 hours. This was first passed down from the ancient Egyptians. Our Ming Dynasty has continued the twelve-hour system. After all, one hour for us is equal to two of them.  Hour."

    "Europeans like to build large clocks on their churches or large buildings to calculate time. They divide one day into 24 hours, but there are only twelve digits in European clocks. They divide the day into two parts.  Noon is the midpoint, and there are twelve hours respectively.¡±

    ¡°Then an hour is divided into subdivisions. An hour has 60 minutes, and each minute has 60 seconds. Therefore, European clocks have corresponding hour hands, minute hands, and second hands.¡±

    When Zhu Houzhao heard Liu Jin¡¯s words, he began to explain in detail.

    "Hmm~"

    Liu Jin nodded slightly when he heard this. This is an internationally accepted method of calculating time in later generations. Unexpectedly, Europeans had figured it out very early.

    "One revolution of the second hand is one minute, one revolution of the minute hand is one hour, and one revolution of the hour hand is twelve hours, which is half a day. If it is two revolutions, one day has passed."

    ¡°I have to say that Europeans are indeed better than us in this regard.¡±

    "They divided time in detail, and then used mechanical rotation or mechanical swing to calculate time very accurately. In contrast, in the past, we only calculated time based on clepsydras, hourglasses, or sundials, although roughly  They can all know the time, but they cannot know the time as accurately as the Europeans."

    When he said this, Zhu Houzhao couldn't help but praise.

    In the past, I always felt that the people of Ming Dynasty were the best in all aspects, but since coming into contact with some European craftsmen, Zhu?I don¡¯t mean it as a compliment, but as a sign of admiration from Fazi¡¯s heart.

    The conclusion he reached is highly similar to the conclusions reached by some experts and scholars in later generations, which is admirable.

    "Haha, I think so too, I am a genius!"

    When Zhu Houzhao heard this, he was so happy that his tail was raised. Then he looked at the clock on the table and said.

    ¡°I learned from European clock-making technology, combined it with our existing Ming technology, improved it, and created this clock.¡±

    "I divided the day into twelve hours, one hour and two hours, one hour and sixty minutes, and one minute and sixty seconds. I used the rotation of mechanical gears to drive and the mechanical spring to provide power, and created this history of our Ming Dynasty.  The first watch on the Internet."
