Screws are an indispensable tool in hardware technology and an important step towards industry.
Most of the previous Lishan artillery used iron plates as buckles, and then used springs to increase elasticity.
Lishan already has screws, but now the screws in Lishan are very rough, the screws are made very big, and the nuts are still square.
Of course, screws have always existed in the history of human production. Since ancient times, the wisdom of working people has been used in production and can create many tools.
Screws are naturally included.
But the screws Lishan is casting now are different. They are precision screws for metal casting.
The workshop uses tools that can tap metal parts, but these are all manual and very tiring to use.
There are always endless technical problems to solve. After Lishan used copper, he could use his brains on screws.
Copper has good ductility and is essential in all aspects of casting.
This is also the reason why Lishan wants to win the right to cast copper no matter what.
Outside the workshop, Xiao Qingqing and her younger brother had just returned from listening to Mr. Ouyang Xun's lecture. The two siblings had listened to the class all morning and were feeling dizzy at the moment.
"Sister, daddy is in the workshop again."
Xiao Qingqing looked over after hearing this and whispered: "The bell tower on the mountainside hasn't been built yet. Daddy is really busy."
Xin Xin'an nodded heavily, "Aunt Xiaohui and Aunt Xiaowu seem to have endless things to do."
"Yes, we also have endless books to read."
Hearing what her sister said, Xiao An's fat face suddenly fell.
It is spring again. In April, the clear sunshine shines down, and the warmth gradually returns to Guanzhong.
Zhang Yang wrote a letter to Chaozhong and asked his aunt to deliver it.
Xiao Qingqing came with a piece of paper and said, "Dad, Li Xiang is here."
Speaking of the child Li Xiang, he is too dull, and he is not as cheerful as the children from Lishan who grew up in the East Palace.
Zhang Yang sat down again and asked, "The prince is here too?"
"The prince didn't come, but Li Xiang came out of the East Palace and said he wanted to ask dad a question." She put a piece of paper on the table and said, "She said she wanted dad to write down his wish."
Zhang Yang said calmly: "Why should I ask my father to write it?"
Xiao Qingqing also looked confused and whispered: "Yes, why do you want dad to write it?"
Zhang Yang stood up and wrote, "May the Tang Dynasty be able to go through all the ups and downs. May the Tang Dynasty be able to turn the tide even when it is about to collapse. May the pain of the Tang Dynasty be healed. May the banner of the Tang Dynasty be healed."
It can be inserted into every corner of the world, but it is still so simple and cute."
Xiao Qingqing looked at it and read it out loud unconsciously.
"May the hearts of the Tang people always be accompanied by dreams, may the children of the Tang people be able to thrive, may the people of the Tang Dynasty be able to heal the mountains and rivers, may the people of the Tang Dynasty be able to have dreams, and may they be able to yearn for beauty and strive for it..."
After writing this, he handed the paper to his daughter and Zhang Yang said: "Okay, there are many more, so I won't write them down."
"Well, my daughter will be given to Li Xiang right now."
An hour later, she came back, "Dad, Li Xiang asked again, if the Tang Dynasty becomes rich and powerful, will it make the same mistakes as it did in the prosperous Han Dynasty?"
Zhang Yang said with a smile: "Then we must pay close attention to the construction of ideological and moral character. The book that a person must read in his life is the book of ideological and moral character. The so-called ideological and moral character refers to thoughts and moral character, and pay close attention to the construction of the spiritual world."
"Well, my daughter will go and reply to Li Xiang right now."
There are many people coming for spring outings this year. April in Guanzhong is the time when everything comes to life.
Li Xiang sat on the shaft of the carriage, the paper in his hand moving with the wind. The eight-year-old Li Xiang read: "May the Tang Dynasty go through all the ups and downs, may the flag of the Tang Dynasty be planted all over the world, may the Tang Dynasty be overturned."
There are people who can turn the tide..."
"May the children of the Tang Dynasty grow up vigorously, and may the hearts of the Tang Dynasty people always have dreams..."
The child's words reached Li Chengqian's ears, and the Prince of the East Palace asked: "This is..."
Li Xiang replied: "When the boy asked about the wishes of the Marquis of Lishan County, he wrote these to the boy."
Li Chengqian looked at the handwriting and nodded, "Well, this was written by Zhang Yang himself."
He whispered, "May the people of Tang Dynasty have dreams in their hearts..."
This was Zhang Yang's wish, but his wish did not mention Lishan. He gave all his wishes to Datang.
Li Xiang said again: "The boy asked about the future again. One day, when the Tang Dynasty becomes rich, what will happen if it becomes like the prosperous Han Dynasty?"
Li Chengqian asked with great interest: "What did he say?"
Li Xiang replied: "The county magistrate said that we must pay close attention to the construction of ideological and moral character, and we must do a good job in ideological and moral construction."
"Well, I understand."
Li Chengqian looked into the distance and took a deep breath.
The Wei River flows eastward, and the water in the river is sufficient to irrigate the fields along the way.
Lishan's letter was delivered to Chang'an City, and someone was running quickly down Zhuque Street.
Di Renjie was sitting on the street supporting Zhang Jianzhi, who was drunk, when he saw the man running past like the wind and running towards the Zhuque Gate with flying strides.
Zhang Jianzhi opened his eyes slightly and said, "Is this another urgent report?"
"Well, maybe."
Di Renjie supported him and replied calmly.
In Zhongshu Province, a roll of paper sent by the prince was being circulated by everyone. Zhang Yang made many wishes for Datang.
The more Chu Suiliang looked at it, the more something was wrong, but he couldn't tell what was wrong. He always felt that something was missing.
Suddenly, my heart jumped and I thought of it.
I should add that I hope the Tang Dynasty will last forever.
Of course, these words are good, but who can guarantee that the Tang Dynasty will last forever and be as powerful as the Qin and Han Dynasties, and it will also become a chapter in the annals of history.
"Cen Zhongcheng, a letter from Lishan."
Cen Wenwen was looking at the memorials for supporting teachers from various places this year, and his thoughts were interrupted by the clerk on the side.
He reached for the letter, read the words in it, frowned at first, then stood up and hurried out of Zhongshu Province.
In the Hall of Wude, Li Shimin often came here to take a look. This was the place where the Supreme Emperor Li Yuan lived. The sitting man beside him was recording His Majesty's words and deeds today.
This is a daily note. It is natural for His Majesty to write down his visit to Wude Hall today. Although the Supreme Emperor Li Yuan no longer lives in the palace, His Majesty will still come here often to visit and miss the years when his father was here.
However, as long as His Majesty says a word, Li Lang will erase the matter from his notes. Most of the time, His Majesty will not do this, unless His Majesty has a quarrel with the Marquis of Lishan County.
"Your Majesty, Cen Wen is here."
After Eunuch Wang went to Lishan, Li Shimin felt very uncomfortable because these eunuchs were not as effective as Eunuch Wang, and their voices sounded alternately louder and softer.
If the sound is too loud, Li Shimin will feel like his brain is being slapped.
If the sound is too low, you will not be able to hear clearly.
They always have a bad grasp of proportion.
Li Shimin said in a deep voice: "Summon him into the palace."
Cen Wenwen stepped into the palace and handed over the letter, "Your Majesty, this is a letter from Lishan."
"What? What does he want Datang to do?"
Hearing this, Cen Wenwen secretly sighed inwardly at how fast the news came. Less than half an hour after Zhongshu Sheng received the paper from the prince, His Majesty already knew about it.
Li Shimin took the paper and looked at it with a frown, "I asked him to write more memorials, but after a winter he still didn't submit one to advise me. Why is it that today..."
He stopped mid-sentence, and His Majesty fell silent again.
Cen Wenwen bowed and said: "Your Majesty, I would like to take a trip to Lishan Mountain."
Li Shimin sat down, his eyes darkening a lot, "He actually wants to sell papermaking technology to the court."
Cen Wenwen replied: "What the letter describes is the complete papermaking technology, including the secret recipe of pulp and recycling technology."
Of course the court wants it, which is a good thing, but there is no joy in His Majesty's eyes because he saw the price. To buy the complete papermaking technology, the court would need 100,000 guan!
Cen Wenwen said in a deep voice: "Your Majesty, Lishan can make thousands of feet of paper in one day..."
"Why didn't he come and grab it?"
Li Shimin slapped the letter on the table and cursed angrily.
In the middle of his words, Cen Wen was scolded back by His Majesty's angry shout.
"This Zhuzi! This Zhuzi!" Li Shimin paced back and forth and said again: "One hundred thousand guan! One hundred thousand guan! He thinks how much money I have, his family fortune in Lishan is enough to squander it, but I never dare to squander it, then
It’s all based on the country!”
Cen Wenwen said quickly: "Your Majesty, please calm down."
"Calm down?" Li Shimin glared and said, "Today he dares to ask me for a price of 100,000 guan, and tomorrow it will be 300,000 guan, or 1 million guan!"
"Don't think that I don't know his methods."
"He sold a papermaking technique three times. He has used it up long ago. Since it has no value, it should be dedicated to me."
"Shuzi! Shuzi!"
His Majesty's eyes turned red as if he was so angry.
Cen Wenwen wanted to persuade His Majesty to calm down. If he obtained the complete papermaking technology, he would be able to obtain a factory in Lishan. If the court could get a glimpse of the essence of casting technology, it would also benefit.
It depends on the situation... Your Majesty is very angry, so he probably won't be able to persuade you to go in.
Li Shimin had just been in a good mood because of Zhang Yang's wish, and now he was so angry because of Zhang Yang's letter that he slammed the table.
The living man was recording, the pen in his hand kept writing, and the handwriting was racing, recording the scene that happened in front of him.
Li Shimin glared at the living man and said angrily: "No need to remember it!"
The pen in Qi Julang's hand suddenly stopped.
"Tear it apart!"
Qi Julang quickly tore off the page, leaving just one page missing from the Emperor of the Tang Dynasty's daily life notes.
Seeing that His Majesty was about to walk out of Wude Hall, Cen Wenwen said again: "Your Majesty, what are you going to do?"
Li Shimin had a dark face and said coldly: "I will personally lead the troops to Lishan Mountain."
Cen Wenwen asked: "Your Majesty, are you going hunting?"
"Yes! Hunting!" Li Shimin gritted his teeth. His original intention was to capture the kid from Lishan alive in Chang'an City and cut his stomach open first to see what his heart and liver looked like.
"Your Majesty! I am willing to go to Lishan Mountain to discuss with the county prince, but the price is definitely not one hundred thousand guan."
"Not even fifty thousand guan!"
Seeing His Majesty's addition, Cen Wenwen stopped talking and replied in his heart: "I understand."
Today, His Majesty lost his temper again. Li Shimin walked into the Li Zheng Hall and sneered, as if he had seen Zhang Yang hanged in front of Chengtian Gate.
"Have someone clean the Chengtian Gate again. It has not been cleaned for a long time."
The maid on the side listened and hurriedly gave the order.
"Hehehe..."
Hearing their father's sinister laughter again, Dongyang and Gao Yang were frightened to the point of trembling, thinking that their brother-in-law was really weird, how could a letter make their father do this.
"Your brother-in-law wants me to buy his papermaking skills with 100,000 guan." Li Shimin put down his tea bowl, shook his head and sneered, "Haha, 100,000 guan."
Dongyang and Gaoyang didn't dare to say a word at all, for fear that His Majesty would be furious if they said anything.
In fact, Lishan did hand over many instruments to the Central Government many years ago. As for those instruments, craftsmen from the Ministry of Industry spent three or two months working on them, dismantling and reinstalling them. Only later did they realize that without Lishan's technology,
Many parts cannot be manufactured.
For example, a small thing like a spring has troubled the Ministry of Industry for many years.
How on earth was this little thing made?
The Ministry of Industry can make large springs, but they are far from as elastic as Lishan.
Later, this reason was attributed to Lishan's iron casting technique.
The iron material fired from Lishan is so symmetrical that after it is divided into equal parts, the weight of each piece is about the same.
There must be a hidden secret to this casting method.
An experienced blacksmith can tell that Lishan added something else when casting the iron.
Due to His Majesty's instructions, Cen Wenwen worked all night to compile a report about Lishan. Lishan not only announced the secret recipe of soap to the cooperating counties, but now also wanted to hand over the papermaking technology to the court.
It seems that Lishan is abandoning these secret recipes, and everyone is profitable. Cen Wenwen thinks so from beginning to end.
If Lishan feels that these secret recipes can be abandoned, then for Lishan, abandoning these secret recipes must be for the greater benefit.
The next day, Cen Wenwen found Jin Wang Li Zhi.
Li Zhi is a disciple of Lishan, and he just came out of the mountain last year. In terms of understanding of Lishan, His Royal Highness the King of Jin is the best in the court.
But today Li Zhi and Di Renjie were sitting in Qujiang Pool drinking wine.
Di Renjie said: "Cen Zhongcheng, why is there still construction in Qujiang?"
"yes."
Cen Wenwen replied to deal with this thirteen-year-old brat.
Di Renjie looked at the working men carefully and said, "Building a house is actually very simple, isn't it?"
Let Di Renjie talk to himself, Cen Wenwen looked at Li Zhi, "Why?"
Li Zhi was puzzled: "Why why?"
"Why did Lishan take away the soap and sell the papermaking technology to the DPRK?"
Hearing this, Di Renjie was shocked, and then His Highness King Jin heard another incredible thing.
Li Zhi frowned and said, "Are you selling off your property?"
Cen Wenwen smiled in astonishment, waved his hand and said: "Impossible."
"Is that because my brother-in-law thinks that soap and papermaking are no longer profitable?" Li Zhi said worriedly: "In fact, when I was in Lishan, I concentrated on studying skills and rarely involved Lishan's production plan."
It can’t be said that I didn’t study well or how well I studied at Lishan.
Among the brothers and sisters who studied in Lishan, I was a poor student.
I can't even care about the production plan, and I can't even keep up with my studies.
Now Cen Wenwen came to ask, Li Zhi tried his best to put on a profound expression and said: "Brother-in-law once said that Lishan's productivity is limited."
"Thank you, His Highness King Jin."
Cen Wenwen left quickly.
Li Zhi shook his head and said: "I don't understand, I don't understand, why is Cen Zhongcheng leaving in such a hurry? Is it possible that he is mistaken?"
