Chapter 188
As for the moment before, he wanted to chop off Su Chen's hand with a knife, but now he has completely forgotten it!
"Li Zhi, explain the use of this watch to His Majesty and the Queen Mother. I will go to the East Palace to invite the prince to come over. I still have a watch here."
Su Chen stood up and said to Princess Changle, and Princess Changle sat between the couple as he said.
"Come here, invite the prince to come to Lizheng Hall!" Li Shimin ordered Wang Defa outside the hall.
"Yes!"
Wang Defa, an old eunuch outside the hall, accepted the order.
"Then wait for the prince to arrive and explain it together." Su Chen suggested after sitting down.
"Your Majesty, this thing is called a watch, take a look first." Su Chen handed the watch to Li Shimin.
"Watch? Good, good! Li Zhi, tell me now, what is the wonderful use of this watch, no need to wait for Gao Ming." Li Shimin handed the watch to Changle, he didn't know how to use this watch yet.
Li Shimin was too curious, how could he wait for Li Chengqian.
"Father, I will help you put on the watch first. Father, stretch out your left hand." Changle took the watch from Li Shimin and put it on for him.
"Oh? Put it on your wrist, that's good."
After Changle helped him put it on, Li Shimin raised his wrist and looked at it carefully.
Five minutes later, Li Shimin and his wife couldn't wait any longer.
"Lizhi, why can this fine needle jump on its own without external force?" Empress Changsun suddenly asked.
Li Shimin was also curious about this, and the couple stared at Princess Changle, waiting for her answer.
"Father, mother, this watch is used for timing. Just like the "clepsydra" we use every day," Princess Changle said slowly. She wanted to wait until Li Chengqian arrived before she could explain in detail.
If someone took the watch and checked the "clepsydra", they would find that there was an error.
Because Su Chen taught Changle that a quarter of an hour was fifteen minutes, and the Tang Dynasty at that time used "hundred ke" as a day and night.
One ke is equivalent to 14 minutes and 24 seconds. It was not until the late Ming and early Qing dynasties that Western mechanical watches entered China, and then one ke was divided into 15 minutes, that is, a day and night is 96 ke.
However, the "sundial", an older timekeeping tool in China, was the first to define one ke as 15 minutes.
This "sundial" needs to be placed outdoors and can only be timed by sunlight, so it is not popular.
As soon as Princess Changle finished speaking, Li Chengqian hurried to Lizheng Hall.
"The son greets the father and mother!" Li Chengqian saluted respectfully as usual.
But Li Shimin and his wife ignored him, and didn't even look at him.
Su Chen took out a watch and waved to Li Chengqian, "Prince, come and sit."
He got up and moved to the side and sat at the edge.
"Brother-in-law, is this a clock?" Li Chengqian asked with the watch. Like Li Tai, he had finished elementary school mathematics and had seen this picture.
"Yes, but this is called a watch."
Li Chengqian nodded. He had learned the theory. Because he also treated the calculations about clocks in the textbook as math problems.
He didn't know that the main function of this clock was to tell time.
"You two should be quiet, Lizhi, you continue talking." Li Shimin glanced at Li Chengqian and shouted.
"Okay, father!"
Princess Changle simply stood up, left her seat and stood opposite them, explaining slowly.
It took about fifteen minutes to carefully explain what Su Chen taught her to Li Shimin and Empress Changsun.
Li Shimin seemed to be thinking about something, and then asked excitedly:
"Lizhi, do you mean that these three hands can move by themselves day after day without stopping?"
Princess Changle nodded, "Yes, father. Especially your and mother's watches, which never stop and will not have any deviation. It also has night vision function, even in the dark night, you can see the time clearly without a lamp."
Li Shimin was overjoyed, "Hahaha, treasure, I am very happy!"
Empress Changsun also smiled, and at the same time, she was curious about what Su Chen and Changle's watches would look like.
"Lizhi, where are your and Su Chen's watches!" Empress Changsun asked.
"Mother, the watches that Su Chen and I wear are ordinary, look." Princess Changle raised her sleeves, revealing the watch and said.
Then, Princess Changle leaned over to Empress Changsun's ear and whispered something.
"Couple watch?"
Princess Changle told Empress Changsun the reason for the exchange of watches.
"You girl, you are making a fuss!" Empress Changsun poked Changle's forehead with her finger, "Su Chen, come here."
"Okay, mother!" Su Chen came to Empress Changsun.
Empress Changsun looked at Su Chen with a loving face and smiled:
"Su Chen, I heard from Li Zhi that these two watches are a pair of couple watches. If so, change them back. Mother thinks the other two watches are also good."
Li Shimin, who was standing by, also heard it,After thinking, he said:
"Boy, you are filial enough. Couple watches are suitable for you young people, so it's okay to change them."
Li Shimin was generous for once.
Su Chen smiled slightly, "Your Majesty, mother, this is wrong. You two are a rare couple in the world, and you are a model couple!
This watch is most suitable for you two.
Li Zhi and I are still young, and the watch is convenient for timekeeping. There is no need to be particular about other things.
If there is a chance in the future, I will give Li Zhi a more meaningful gift."
Li Shimin nodded with relief.
"By the way, Your Majesty, I have something to discuss with you today." Su Chen deliberately changed the subject.
"Well, you talk, I listen!" Li Shimin said, and at the same time, he patted Li Chengqian's arm with the back of his hand, asking him to move to a seat for Su Chen.
Su Chen smiled at Li Chengqian, and said after sitting down:
"Your Majesty, I want to promote cheap books and paper in the Tang Dynasty as soon as possible. Therefore, I want to let the ten families in the Tang Dynasty who have the right to operate fine salt participate. In this way, books can be quickly promoted in various prefectures of the Tang Dynasty."
Su Chen's idea is very simple. He will teach them the papermaking and movable type printing technology, and let them open papermaking and printing factories in the prefectures they are responsible for.
Today's Tang Dynasty has inconvenient transportation. If all books need to be transported from Chang'an to various places in the Tang Dynasty, the cost will be high.
Some distant places may take a month to arrive.
In this way, even if the cost of paper is low, books will not be cheap.
After Su Chen finished speaking, Li Shimin nodded slightly and thought.
Now Li Shimin is a little different from before. If it was before, he would first think of making money.
Later, he figured it out himself. Su Chen was right. The royal family can't just think about making money.
"Boy, if they master the new papermaking and printing technology, will the price of books and paper increase?" Li Shimin asked. This was his only worry. Su Chen smiled and said, "Your Majesty, you might as well think about fine salt. Now it is almost impossible for anyone to sell fine salt for an extra penny per pound. Because the fine salt refining technology has been made public, it is no longer dominated by one company. The same is true for papermaking and printing." Li Shimin nodded and smiled when he heard this, "What you said makes sense! Well, you and Gao Ming can do it. I don't care." "Your Majesty, there is one more thing."
