The Grandmother in the Siheyuan

Chapter 114: Crazy to no end
"That's pure feudal superstition." Liu Hua said without even looking up: "According to my analysis, the Forbidden City has red walls. As we all know, red pigment contains iron, such as iron oxide, which is magnetic. Many years ago, it was a rainy day, and when the palace maids passed by, there was thunder and lightning. The strong current recorded the voices and shadows of the palace maids in these magnetic materials."

Wang Danian suddenly realized: "That's right. The images appearing during thunderstorms are because the strong electric current plays out the information in the magnetic material."

"Yes, so we can use iron oxide as a magnetic material and make a tape like a movie reel." Liu Hua smiled and said, "Think about it, isn't it much more convenient to record like that than using a wire recorder?"

"How wide is the film? If you use that as a memory, you'll have to make a much larger tape recorder."

"Stubborn." Liu Hua said jokingly, "The amount of information in sound is obviously not comparable to that in movies. It's much smaller. You can make the recording reel smaller, three or four millimeters wide, and then put a shell on the outside and roll it up inside. It's much more convenient than a wire recorder."

"If iron oxide is used as a magnetic material, its price is much cheaper than film." Wang Danian suddenly realized: "Then this will be my next research direction."

"Don't think about the next one yet, just finish the task at hand. This is a huge project."

Wang Danian shook his head and said, "I will not participate in this work in the future. I originally thought that this was a promising thing and I could get some credit for it. But after studying it for so many days, I found that the prospect of this thing is too great and my wisdom cannot keep up. I guess there will be more professional and more advanced scientists to study it in the future, and I will not be involved."

"I won't continue to study it in depth either." Liu Hua agreed, "At first I thought so too. This is a useful tool, but now it seems that this thing has a wide range of applications. After all, I'm just a high school student, and my knowledge reserves don't support me to continue to study it in depth."

Liu Hua actually just wanted to withdraw in time. When he came to this era, he had already made plans. He would stay alive until he was absolutely safe. As the old saying goes, it is better to be safe than sorry.

After the National Day, the manual forklifts produced by the steel rolling mill began to be distributed to various large and small factories, which caused a storm of varying sizes.

Because it greatly improved work efficiency and reduced the workers' labor intensity, it received unanimous praise from the workers and was also reported in many newspapers.

These media people are also very interesting. They searched all over the world and found that manual forklifts are unique to our country and are truly the best in the world. As a result, the steel rolling mill became famous again, and Li Huaide was praised by his superiors again.

Ever since this guy's story was published in the newspaper, Li Huaide couldn't hold back his smile. He also behaved unusually kindly in the factory, and he would praise anyone he saw to show his big shot demeanor.

Needless to say, Liu Hua, the noble man, received a lot of bills, regardless of whether they were useful or not, as long as they were in Li Huaide's drawer, he stuffed them into Liu Hua's arms. There were even two bills for menstrual pads, which made Liu Hua laugh and cry.

In the end, the vote was given to Liu Feifei, which caused her girlfriend to blame her. At that time, these were taboo topics that would make women feel extremely embarrassed.

But Liu Hua didn't care. He thought that in his previous life, let alone buying sanitary napkins for his girlfriend, even buying a pack for his female friends while going to the supermarket would not be a problem.

About half a month after the National Day, the machine tool was finally modified. Through fixed program settings, one only needs to load the workpiece and press a button, and the machine tool will start automatic processing.

This time, Li Huaide was not unable to suppress his smile, but he could not close his mouth at all. He was so surprised that it completely overturned his cognition. The machine tool could move by itself and do whatever it needed to do. Its movements were more skillful than those of an old master.

Liu Hua took a processed part, measured it with a caliper, and shook his head: "Sure enough, this machine tool is not yet capable of finishing, the accuracy is still far from perfect, but it should be more than enough to produce gears." Li Huaide shook his head: "What else are you dissatisfied with? This is simply a miracle. I know you want to keep improving, but our factory is in this condition now. It's good enough to be able to research to this extent. Don't interfere with the next research, I will hand it over."

Liu Hua was stunned for a moment. He didn't expect Li Huaide to say that.

Li Huaide said with great sorrow: "I am doing this for your own good. If you continue to interfere, our factory will not be able to keep you. It's not that I want to block your future. Your grandfather said that you should calm down a little. If you go to other places, will anyone treat you as well as I do?"

Liu Hua smiled and nodded: "I know. On the National Day, I discussed with Wang Danian that neither of us would interfere in the following matters. Our accumulated knowledge is not enough for us to continue the research."

"That's good, that's good." Li Huaide nodded: "You guys just take a good rest, I'll go to the department right away, this matter must be reported to the higher-ups as quickly as possible, this is a top priority."

Li Huaide rushed out of the test workshop, and in less than five minutes he drove out of the steel rolling mill and arrived at the First Ministry of Machine Building without stopping.

The secretary of the leader was shocked: "Lao Li, what's wrong with you? Is there something serious happening in the factory?"

"Where are the leaders?" Li Huaide shook his head. "Something did happen, but it's a good thing. I'm going to bring a few leaders to our factory to have a look today no matter what."

The secretary also shook his head: "Impossible, the leader's schedule is arranged in advance, and there is a meeting to be held today, so we can't delay it."

"No meeting is more important than what I am going to report today."

The two were arguing outside the leader's office. The leader was preparing to have a meeting, so he pushed the door open and came out, just in time to hear what Li Huaide said.

"Li Huaide, you are so crazy now. The meeting we are about to have is very important, but it is not as important as what you want to report. What important things can you have?"

Li Huaide immediately put on a smiling face: "Leader, what I am going to say next is a big deal, you must stand firm."

"you say?"

Li Huaide took a deep breath, then smiled and said, "The engineers in our factory have made a CNC machine tool, and the price is quite cheap. It is modified based on the C620."

There were three or five people at the scene, all of whom were leaders of the First Ministry of Machine Building. After hearing what Li Huaide said, the scene became very quiet, extremely quiet.
