Husbands and wives do not have to have common topics in the same field.
When Li Qinzai talked about physics, Cui Jie couldn't understand it at all. But if Cui Jie talked to Li Qinzai about embroidery work, would he understand it?
Each has his or her own merits and lives. Husband and wife are not business partners. There is no need to have common ground on work topics. It is enough to brush the dust off the other person's body when he or she is exhausted.
The meal was eaten very slowly, with candlesticks standing in the middle of the table, and the couple laughing and joking. It felt a bit like a romantic candlelight dinner.
The atmosphere has been heated up here. After dinner, of course we have to do something that we like each other, in the kitchen, in the wing, on the bed, on the futon, by the well...
Hmm? I seem to have wandered into some strange place...
It's a pity that Li Qinzai didn't accomplish anything after eating.
Cui Jie's aunt is still in love with her, and Li Qinzai can't do anything like running a red light.
Fortunately, Cui Jie still has dexterous hands and feet, as well as alluring red lips, pink curtains and red curtains, charming spring scenery, and bone-eroding ecstasy, so there is no need to go into detail...
The moment before he was about to tremble, Li Qinzai suddenly understood why men also like mermaids. How could he not be happy about this situation?
…………
The next morning, after Li Qinzai woke up, he sorted out the drawings, and then ordered Bu Qu to go to Chang'an City quickly and invite several skilled blacksmiths to come over. He also allocated money from the Duke's Mansion to purchase ten thousand kilograms of pig iron.
When Liu Asi heard about such a large purchase, his expression suddenly tightened. He knew that the Fifth Young Master must be making big moves, so he did not dare to neglect and rode his horse to Chang'an City in person.
In addition to completing the Fifth Young Master's mission to the letter, Liu Asi must also report truthfully to his father-in-law.
When Fifth Young Master wants to build a new gadget, the entire Duke's government attaches great importance to it. Li Ji has already given instructions and must be informed as soon as possible.
In the afternoon, more than ten blacksmiths rode the Li family's carriage and quickly arrived at Ganjing Village.
But Liu Asi hasn't come back yet. The task of purchasing ten thousand kilograms of pig iron is too huge and cannot be completed in one day.
Interestingly, after Liu Asi reported the truth to Li Ji, Li Zhi from the Taiji Palace also knew that Li Qinzai was going to make something new. Not only did he personally order the blacksmiths from the Ordnance Supervision, but he also asked the inner government to immediately send 10,000 kilograms of pig iron overnight.
Go to Ganjingzhuang.
Most of the blacksmiths in the Ordnance Supervision were former soldiers and had a military temperament. They all stood in front of Li Qinzai and asked Li Qinzai for orders with stern expressions on their faces.
Li Qinzai scratched his head. The battle was a bit big. It was just a hydraulic press. There was no need to be so grand. It made it seem as if the building was about to collapse and he was the only savior.
Li Qinzai felt a little moved when he thought that his grandfather and Li Zhi both attached so much importance to his creation of new things.
It feels really good to be valued and needed by others.
Unfolding the drawings in his hand, Li Qinzai pointed at the drawings and explained one by one.
The blacksmiths don't know anything about hydraulic presses, but they know how to make iron.
It was enough to know what kind of object Li Qinzai needed to create. As for what the object was used for, the blacksmiths did not know and did not dare to know.
A complete hydraulic press requires a high-pressure water pump and a liquid-filled cylinder, as well as a large iron cylinder for water storage. However, in this backward era when the industry was almost blank, high-pressure water pumps and liquid-filled cylinders were a bit difficult.
So Li Qinzai decided to build a primitive and crude version of the hydraulic press, retaining only key parts such as the large iron cylinder, iron ingots, anvils, and pistons. The high-pressure water pump and liquid-filling cylinder could only be reluctantly removed, and an iron water channel was used instead to serve as a drain.
The function of water is to use water, and a water injection port is required above the iron cylinder.
The gravity generated by the weight of water is used to add kinetic energy to the piston and the iron ingot, and two sets of pulleys are used. After the iron ingot falls, the pulley set is used to lift the iron ingot, and then knock it down again. In this way, the effect of hydraulic forging can be achieved.
After Li Qinzai's detailed explanation, the blacksmiths finally understood what kind of parts Li Qinzai needed, so they all geared up and said they would build what he needed as soon as possible.
The pig iron was transported to Ganjingzhuang that night. Li Zhi obviously took it seriously and actually sent a team of Yulin guards to escort it.
Early the next morning, Li Qinzai came to the reservoir. The reservoir was basically completed. Li Qinzai ordered a water injection port to be connected at the bottom of the reservoir, and then used a water truck to introduce Weihe River water into the reservoir.
On the other side, the blacksmiths have temporarily built a row of simple sheds under the reservoir. The furnaces have been set up and they are hammering pig iron into steel.
More than a dozen blacksmiths were in full swing, and people had already gathered outside the shed. The farmers stopped working and gathered around the blacksmiths curiously, secretly discussing what new thing Fifth Young Master was going to build this time.
In front of the crowd, the students of the school stood in front of the blacksmith as a matter of course, observing openly and asking Li Qinzai questions from time to time.
The crude version of the large iron cylinder has begun to take shape. The huge iron cylinder completely occupies the space of the shed. The students looked curiously at this new thing that they had never seen before. Their expressions became more and more impatient and wanted to see it.
until it is fully formed.
Li Qinzai was also quietly watching the blacksmiths working, and said calmly to the students: "Do you remember what I said? Arithmetic is just a tool, it ultimately serves physics."
The students nodded one after another.
Li Qinzai added: "Today I will let you see what 'physics' is all about and why I say it can change the world."
The students nodded again. In the crowd, the eyes of the female top student, Princess Xuancheng, shone brightly. Her expression was excited but suppressed. Her restless little hands kept rubbing the corners of her clothes. She was obviously very excited inside.
Li Qinzai opened a window for her life. Today, she wanted to stand on tiptoe and see what kind of world was outside the window.
She's about to see it.
Beating again and again, the impurities in the pig iron are separated, and the iron block gradually takes shape.
Two hours later, a large iron ingot made strictly according to the dimensions specified by Li Qinzai was shaped under the hammers of the blacksmiths.
Next, the piston and drainage channel were built. Below the reservoir, farmers were installing pulleys. The atmosphere was very comfortable as everyone performed their duties.
The students also stepped forward to help. With more people, work was easier to do and the efficiency was very fast. By the afternoon, all the parts Li Qinzai needed had been completed.
Li Qinzai directed the villagers to work together to install the large iron cylinder under the reservoir, and use a pulley block to install the large iron ingot under the large iron cylinder. The iron ingot and the iron cylinder were connected with a piston, and the inner wall of the iron cylinder was lubricated with grease.
Soon, a primitive and crude version of the hydraulic press finally took shape.
Li Qinzai watched with satisfaction as the hydraulic press stood under the reservoir, and finally ordered people to install the water injection port and drainage channel.
Following Li Qinzai's order, the water from the water injection port continued to flow from the bottom of the reservoir into the large iron cylinder.
