Liu Dahao walked over with his luggage and looked at the two people standing at the door, thinking that they were shocked by the house he built.
"How about Zheng'er? Our family is very impressive now, isn't it?"
Liu Zheng nodded dully.
Then I made up my mind that this house had to be demolished and rebuilt!
Seeing that his son agreed, Liu Dahao laughed loudly: "Did you see it, Sanniang, you still say it's annoying, but our son understands me, you guys don't know what art is!"
Feng Sannian hugged Xiao Liu and rolled his eyes at him.
Liu Zheng turned his head, looked at his father who wished he could write the word "art" on his face, and said in a deep voice: "You did a good job, don't do it next time."
Liu Zheng walked in and whispered to the housekeeper: "Tear down this door quickly, melt it, and redo it!"
"Yes, yes, Master."
The voice was neither loud nor quiet, just enough to be heard by Liu Dahao and Feng Sanniang.
Feng Sanniang looked at Liu Dahao's face and said with a smile, "Our son still understands you."
Feng Sannian carried Xiao Liu Gan and walked into the house. Xie Chan snickered and followed him in.
Liu Zheng came back this time and declined most people's visits.
Liu Dahao laughed as he watched his son playing with his son's son.
Liu Zheng looked at his brother and son and suddenly thought, 'My second master is two years older than me? '
But little Liu Cong didn't seem to think so. He was two years old and said incomprehensibly: "Brother..."
Xiao Liu Qian seemed to understand, babbling in response.
The whole family was stunned when they saw this scene. Liu Zheng complained in his heart: 'What kind of family ethics drama will this develop from now on? '
Liu Zheng shook his head to dispel such thoughts.
At this time, Liu Dahao was lying on the recliner. He remembered something, stood up suddenly, and said with fiery eyes: "Little Liu Qian will be celebrating his 100th day soon."
"With the situation our family is in, we need to do something big!"
"Zheng'er, don't worry, I'll leave this matter to dad."
Just when Liu Zheng was about to speak, he saw his wife and mother shaking their heads like rattles. They were because the matter about the mansion built by Liu Dahao had not yet passed.
Liu Zheng thought for a moment and said, "Dad, I'll leave this matter to you."
"Okay." Liu Dahao patted his thigh, stood up immediately, and went to take care of things.
But Feng Sanniang and Xie Chan's expressions were very ugly.
"Aren't you afraid that your father will come up with something eye-catching?"
Liu Zheng shook his head and said: "Don't be afraid, just do whatever the old man likes. I just see that he is too busy."
Feng Sanniang stopped talking.
Since Liu Zheng became the chief assistant, Liu Dahao's status has also risen. His business can be done well without being sad, and he has made enough money.
Apart from coaxing the children, he had nothing to do and was busy all day long. It would be a good idea to let him hold a hundred-day banquet this time.
…
Another day passed, Liu Zheng, who was also busy, came to Liangzhou Laboratory.
He has to see how the current progress of electricity research is going.
As soon as he arrived at the laboratory, he saw that the researchers he had recruited were engaged in a fierce quarrel.
"Friction generates electricity. We should use the eagerness to create friction wool to collect static electricity."
"No, what's the use of electricity like that."
"What we want to make is electricity that can be put into use."
"Don't forget what Mr. Liu Zheng told us. Using magnets, this is the hand-operated generator I invented. It has been able to continuously generate electricity."
Liu Zheng's eyes lit up when he saw the hand-cranked generator that the stranger took out.
Liu Zheng walked over, and everyone stopped arguing when they saw Liu Zheng. Only this man was still introducing his hand-operated generator.
"I added a magnet and a coil made of copper wire inside. I tried shaking it manually, and it could emit electricity and attract the paper. Although it is very weak, it does exist!"
Seeing that no one opposed him, Bikedong was slightly startled, and turned around to find Liu Zheng standing next to him.
He quickly saluted, Liu Zheng waved his hand, looked at the hand-cranked generator and said, "This thing you invented is quite interesting."
Liu Zheng walked over, picked up the hand-cranked engine, shook it a few times and said, "The structure is exquisite. Judging from the observation of these pieces of paper, it can indeed produce electricity."
"Well, it's not bad."
Liu Zheng looked at him and asked, "What's your name? Why haven't I seen you before?"
Bi Kedong put one hand on his chest and one hand on his back, bowing slightly, which is the French meeting etiquette.
He said: "Hello, Mr. Liu Zheng, my name is Bixi, an engineer from France."
Liu Zheng nodded. Liangzhou's laboratory attracted not only scientists from Long Yan, but also many scientists from other places.
Although France is hostile to Long Yan, many scientists have come to Liangzhou.
After all, France is still a country with a backward monarchy system. The development of this kind of electricity is almost defined as pagan. Liu Zheng saw a lot of Europeans who were persecuted because of these problems, and Long Yan There is still a considerable gap in comparison.
"Long Yan welcomes you." Liu Zheng nodded slightly and smiled.
He looked at the hand-operated generator in his hand again and said: "This thing you made can already produce electricity, but it is not enough."
"Direct current like this can only be produced in time and applied in time, otherwise it will dissipate very quickly."
Everyone nodded. It was indeed true. Even if capacitors were invented, the electricity they captured would easily dissipate.
Liu Zheng said again: "I have an idea."
Everyone pretended to be listening, as if they didn't dare to miss a word.
Liu Zheng said: "Make this hand-cranked engine bigger and use a steam engine as power so that it can generate more electricity."
"And on the other side, we're going to lay lines that still have copper wire to transport the electricity that's produced to the other side, and on the other side, we run the appliances."
"As for what electrical appliances are, I think you've already invented them."
Everyone watched with puzzled eyes as Liu Zheng's finger landed. It was a simple measuring instrument made to measure the presence of electricity. It was composed of countless small pieces of paper.
Everyone was stunned when they heard Liu Zheng say: "Electricity can attract pieces of paper, but if we can control electricity to attract certain small pieces of paper, can we use this electricity to create a machine that can start or transmit signals? ?”
Everyone murmured a few words, and Bi Kedong's eyes became more and more fiery.
According to his observations, if the current becomes larger or smaller, different effects can be obtained on the paper.
In other words, if something is designed on the other end that can block the paper's contact with electricity, then a lot of information can be read depending on the length of time the paper is in contact.
For example, a letter!
This is just an idea, but countless ideas can be obtained based on this idea.
After thinking of this, the eyes of these researchers became fiery again!
They looked at Liu Zheng now as if they were looking at a god. Liu Zheng smiled and did not continue to express his thoughts.
