Chapter 64 Bowstring
Chapter 64 Bowstring
After one class in the morning and one in the afternoon, Liu Xinqi left the school.
After leaving school, I went to visit my mother and found that her mother was very busy. Now all the accounts of Liujiabao have been handed over to her mother, while Li Lian, the master's wife, is responsible for the cashier's work.
That is to say, the mother takes care of the accounts and the mistress takes care of the money.
I chatted with my mother for a while and learned something about Liujiabao’s current economic situation.
Now that Liujiabao has liquidated all the previously seized property, including the Wu family's compensation from Qinglinpu, Liujiabao can barely sustain its operations for about half a year at its current spending rate.
"Until the economy improves, the population of Liujiapu cannot be increased." Liu Xinqi secretly planned.
After saying goodbye to his mother, Liu Xinqi went to find Zhou Yue again. When he found Zhou Yue, Zhou Yue was compiling teaching materials. Liu Xinqi gave her some things he had written when he had nothing to do on the ship, and gave her a brief explanation, asking her to do it herself first. If you don't know how to study and comprehend, you can ask Liu Xinqi when he is resting.
Coming out of Zhou Yue's room again, Liu Xinqi was about to go to the Liu family warehouse to find Liu Zhimu, but he didn't expect to meet Liu Xinshi at the door of the Liu family compound.
Liu Xinshi has recently been responsible for leading the youth reserve team, while studying, training, and learning the skills of their choice.
When I chatted with Liu Lisheng before, I heard Liu Lisheng say that Liu Xinshi did a good job and helped him a lot. These teenagers are also very motivated and energetic, and they completely represent the future of Liujiabao.
"Just in time, I was thinking of looking for you later, come with me." When Liu Xinqi blocked Liu Xin, this was a gate, so it was inconvenient for people to come and go.
Liu Xinqi took him back to Zhou Yue's room. After Liu Xinshi said hello to Zhou Yue, the two found an empty table to sit down. Liu Xinqi asked him: "How are you feeling recently? Have you gained anything?" "
"There are some..." Liu Xinshi replied, then thought about it and said: "The biggest thing I feel is that educated and literate people are really much better than illiterate people. Not only can they understand things, but I can also manage them easily. The benefits of being organized and executing well are endless.”
“I have recently taken care of a lot of former refugee children who don’t know how to read. Sometimes they feel really stupid, and they need to be given verbal instructions multiple times for everything.”
"Don't complain." Liu Xinqi said, "I let you lead the youth reserve team so that you can better shape them. Since they are illiterate, teach them how to read."
"I'm already doing it. Let us, the children of the Liu family, spend an hour every night teaching them how to read. I will check them regularly, and those who don't learn well will be punished."
"Well done." Liu Xinqi praised: "I came to you this time because I intend to cast a spell on you..."
Before Liu Xinqi finished speaking, Liu Xinshi jumped up excitedly and yelled: "Really? Really? It's finally my turn, hahahahaha!!"
"Are you crazy? Sit down." Liu Xinqi scolded.
Liu Xinshi calmed down his emotions and sat down again: "I'm sorry, Brother Xinqi, I'm so excited. I've been looking forward to it for a long time and it's finally come true. You don't know, some of those children are tall and thick. I Sometimes I don’t dare to be too harsh, for fear of being beaten by them. After I receive the punishment, I will make them look good. I usually don’t listen well, I always like to be lazy, and I don’t study seriously..."
When he saw Liu Xin chattering endlessly, Liu Xinqi interrupted him and said: "I cast a spell on you, not to let you bully others."
"No, no, I will definitely use it for the right purpose." Liu Xinshi promised quickly.
Seeing him looking forward to it, Liu Xinqi knew that he didn't need to say anything else. He directly called out a two-star general card "Han Sergeant Cavalry", used it against Liu Xin, and then opened its attributes.
Name: Liu Xinshi
Nationality: Han
Age: 15
Relationship: Ally Attack: 8+35
Defense: 8+35
Strategies: 8
Speed: 9+45
Liu Xin was still a child, and his basic attributes had not yet matured, and it was estimated that they would increase in the future.
"You will be a soldier of the fifth team from now on, and you will be responsible for following your aunt's arrangements. Of course, you must also listen to the words of the clan elders and my teacher. You are still young, so you must listen more and learn more." Liu Xinqi told Liu Xin again.
"Okay, I will be obedient." Liu Xin, who had attached the general card, replied somewhat absentmindedly.
"Go ahead. If you don't understand the changes after casting the spell, you can come to your sister Zhou Yue for advice. You are all in the Liu Family Courtyard, so it is convenient to meet." Liu Xinqi gave the last instruction.
As soon as he finished speaking, he hurriedly agreed when he saw Liu Xin, and then rushed out of the door, probably to show off to his friends.
……
Liu Xinqi came to the Liu family warehouse. Liu Zhimu was in a room full of carpenter tools, studying the crossbow bow Liu Xinqi had made before.
"Any ideas?" Liu Xinqi asked Liu Zhimu.
"I tried to use iron wire as a bow string. It worked fine for the first dozen times. The first few times the range was stronger than that of beef tendon string. However, after using it dozens of times, the range dropped sharply and the bow string needed to be readjusted. The tightness." Liu Zhimu said.
Liu Xinqi understood that he planned to reduce the manufacturing cost of crossbows. Iron wire was much cheaper than beef tendon.
"This is due to the ductility of the wire." Liu Xinqi said
"What does ductility mean?" Liu Zhimu asked.
"The property that an object can stretch into filaments without breaking under the action of external force is called ductility; the property that can be crushed into thin sheets without breaking under hammering or rolling is called ductility." Liu Xinqi said: "You can pull iron into This is how wire is made into a bowstring, and it is also the same principle when iron wire becomes thinner and longer after being stressed, causing the crossbow string to become loose.”
"Then is there any way to solve this ductility?" Liu Zhimu asked thoughtfully.
"It's impossible to completely solve it. If you don't have this ductility, you can't make wire. You can only reduce it." Liu Xinqi replied: "You can solve this problem from two aspects. One is to directly find other cheap and reliable wires. Suitable materials for bowstrings.”
"The second is to minimize the effect of the iron wire becoming loose after being used a few times, such as making a component that makes it easier to adjust the tightness of the bow string and adding it to the crossbow. Or taking advantage of the fact that steel is more resistant to tension than iron, try to find a way to make steel wire. .”
"You can find more smart young people to help you and give them some simple and repetitive tasks."
"Okay, I will try more." Liu Zhimu replied.
After listening to Liu Zhimu's answer, Liu Xinqi asked him again if there was anything else important in Liujiabao's production recently. The key production procedures had slowed down the overall production progress.
"Yes, the adobe bricks needed for making a kang need to be dried before they can be used. This is very time-consuming and takes up a lot of space." Liu Zhimu replied: "Also, there is a serious shortage of straw for mixing mud. Our Liu family Bao’s continuous purchasing has caused the price of firewood on the market to rise by [-]%.”
"The problem of adobe bricks must be solved. A large number of adobe bricks will be needed to rebuild Liujia Fort later." Liu Xinqi replied.
