"Read the ruler first, read the main ruler first, and now the main ruler is worth seven-tenths of five......" Gong Yijian held a vernier caliper that had just been made, and read it according to the method Xiong Jing said, Gong Yindao stood aside and watched, his mouth was tightly closed, and his face was unhappy. Read the sub-ruler again, its overlap with two differences and three grids, that is, twenty differences three, its value is seventeen tenths of twenty? ”

"It's not seventeen twentieths, it's 17 squares multiplied by 0.05, which is 0.85, plus 5.7 of the main ruler, and the total length should be 5.785 centimeters." Although he has six teachers, Xiong Jing doesn't mind being a teacher by himself. However, the later generations of Chu people were not accustomed to using numbers, and often used fractions instead of decimals. "Doctors need to get used to decimals, and decimals are straightforward, which is of great benefit to the calculation of numbers."

"Yes." Gong Yijian is a craftsman, and the craftsman recognizes the number, and a small ruler and a sub-ruler can measure the accuracy that he did not have before, which makes him admire Xiong Jing a little more. It's just that habit, he can't read with decimal places for a while.

"If you want to do a good job, you must first sharpen your tools." Holding the vernier caliper made by the jewelry craftsman of the mansion more than 2,000 years ago, Xiong Jing was very satisfied. This satisfaction was not only due to the fact that he had a high-precision measuring tool, but also because he was finally able to convert the weights and measures of the later generations into the weights and measures of the Chu State. "The scale of the parts is precise and uniform, and the production speed of the waterwheel can be multiplied by the method of flowing water."

Purple Mountain Shipyard has long come up with parts processing drawings and waterwheel assembly processes. The Ford assembly line is used for the assembly of steel machines, and the construction line is used for the assembly of wooden water wheels. Wood is to copper and iron tools like steel to tool steel, and the biggest difference between this and traditional craftsmanship is the interchangeability of spare parts, which is the reason for the doubling of production man-hours.

"Your Highness, time is running out, when will the waterwheel be made?" Gong Zhijian was still looking at the vernier caliper, and Gong Yin Dao was a little anxious, he was the chief person in charge of the production of the waterwheel, and the time was urgent, and he was worried about the delay in the construction period.

"When the builder makes the right part, he can start mass manufacturing." Xiong Jing fully believes in the efficiency of the assembly line, the car is tens of thousands of parts, the water wheel is only a few people, less than a hundred, the process is very simple. "The shipyard steward Shaoyan has come to the government to guide the arrangement."

Shaoyan is Ge's subordinate, and Concubine Zhao is a subordinate of the courtiers, and he has spent half of the time following Xiong Jing in the past two months, and he has been taught by mouth and family, and it is more than enough for him to be a little supervisor. Gong Yindao was still not at ease, he said: "The minister has a reluctant request, please go to His Highness in person?" ”

Although Xiong Jing lives in the East Palace, he handles affairs in his sleep on weekdays, for fear ......that his father will have an accident. Willow bark sap does have a pain-relieving effect, but my father's illness is still good and bad, and the government affairs after that court meeting are presided over by Ling Yin Huangxie.

"His Royal Highness doesn't go in person, and the craftsmen and craftsmen don't want to change the method of production." Gong Yin Dao finally told the secret. "Although the method of flowing water can reduce time, the master and craftsman cannot make a name for it."

"Is there such a thing?" Xiong Jing was slightly surprised, he was a little confused about the relationship between the craftsman and the mansion.

"Yes, yes. The craftsmen who built the house were mostly craftsmen from other countries, and they were hired by Da Chu for use. The name is in the ancient system, under the flowing water law, thousands of waterwheels are man-made, and they can't be named on it, so they don't want to change the strings. ”

"That's right." Xiong Jing scratched his head slightly. The problem is very big, the reason why the waterwheel is expensive is not because the craftsman is not fine, but because the craftsman is too fine. The essence of parts interchange and assembly lines is to make manufacturing accurate and easy, and the first part is exactly the same as the 100,000th part. However, skilled craftsmen are extremely disgusted with this kind of homogeneous production, which will make the hero useless.

"The waterwheel is made by His Royal Highness, and the method of flowing water is also passed down by His Royal Highness...... "Learning from the people around Xiong Jing, Gong Yin Dao is a mouthful of His Royal Highness, and people seem to be crying out - that day, the Yan Dynasty set a target for building a mansion, and the waterwheel needs to be built 20,000 units, and it will be built within three months. With the number of wood workers in the house, plus the assembly of flowing water, this is no problem, but now the craftsmen are unwilling to use the method of flowing water.

"Okay. Don't tell your father first. Xiong Jing felt that he was also responsible, he got up from the atrium and came to the east room, thinking that his father was asleep, but before anyone entered the room, he heard his father cough and said, "Jing'er? ”

"Yes. Father. Xiong Jing walked quickly through the curtain, and when he saw that the king of Chu wanted to get up, he hurriedly helped him up. The chamberlain also opened the window, and the summer sun was shining, and the lush greenery outside the window suddenly brought life to the bedroom.

"Today's business is over?" Xiong Yuan gasped, he held back his cough and asked in a suppressed voice.

"It's not over yet." Xiong Jing settled his father and had to tell the truth. "The child needs to go to the mansion once."

"Go and build a house... "There is something wrong with building a house, of course, there is a problem with the production of the waterwheel, and the waterwheel is actually a project to build momentum for Xiongjing." It's not that the prince doesn't need to build momentum after he has already set up, but the prince has set up the same momentum. "The cost of the watermill is more than three hundred dollars?"

"It's not." Xiong Jing shook his head. At that time, the price of a single waterwheel was set at 300, 400 for a double, and 600 for oxen. This is not the ex-factory price, but the selling price of cities and towns across the country. The purpose is, of course, to benefit the people, and if there is a loss, the government will bear it. "The craftsmen who build the house are not familiar with the production of waterwheels, and they need to be supervised by the children."

"Ling Yin and Jing'er go together?" Xiong Yuan's face suddenly changed, and his cough stopped.

"Ling Yin is not here, Gong Yin Dao, Gong Doctor and Gong Gong will go with the child." Xiong Jing had not yet realized the worries of the King of Chu.

"Do you have to go?" Xiong Yuan stretched out his hand to grab his son, and when his son took his hand, he grabbed his son tightly.

"Need to go once." Xiong Jing said that the craftsmen were unwilling to accept the production of flowing water, so as not to worry his father, and only said that it was a technical problem.

"Long ginger, long ginger." Xiong Yuan grabbed his son tightly with one hand, and shouted urgently to the servant Jiang.

"The king, the king, the old servant is here, the old servant is here." Chang Jiang Ben was resting, and he came crawling when he heard the sound.

"Jing'er needs to go to build a mansion once, Ling Yin, Ling Yin ......" Xiong Yuan wanted to speak and coughed, but he understood what Chang Jiang meant as soon as he heard it.

"There is no change in Yin, and there is no abnormality in Yingdu." Chang Jiang hurriedly bowed down and told him.

As soon as he said this, Xiong Jing suddenly woke up, and his blood rushed to his head for a while: "Father......" He shouted to his father, and then opened his mouth but didn't know what to say.

"The East Palace Palace is equipped with Cai Bao as the general, and the Yin of the sanitation is temporarily replaced by Changjiang." Xiong Yuan's hand gripping his son's clothes finally relaxed. "Jing'er is young, and when she leaves the palace, she will bring palace armor; Whoever goes out of the city will be protected by sanitation. ”

"The child obeys." Xiong Jing couldn't help but bow down, in addition to feeling his father's care, he was very ashamed in his heart - last time his father didn't allow him to go out of the palace to see Lian Po, but he didn't say why.

"Although Jing'er is young, she will be my Great Chu Saint King in the future." Xiong Yuan understood his son's thoughts, patted him and comforted him. "Go ahead. If you don't go, you will be underestimated. ”
