Siheyuan: Banggeng and I are classmates

"I want to make everyone's roofs iron first."

Colored steel tiles are the simplest industrial products that Li Muhua could think of and produce.

The demand is huge and the life cycle is long. It is still selling well in 2019. Most of them are bungalows, and there are still many thatched houses in rural areas.

If colored steel tiles came out now, which would not only prevent water leakage for more than ten years, be easy to install, and cost less than bricks and tiles, Li Muhua estimated that he would be able to count the money until his hands cramped.

"Will the roof be replaced with iron?"

Yang Liu asked in confusion: "Iron is much more expensive than tiles, and it will be corroded by rain. The color is uglier than tiles. Who would replace their roof with iron?"

Seeing Yang Liu looking at him like a fool, Li Muhua explained, "It's just a thin layer of corrugated steel skin, painted with various colors of anti-rust paint. It will definitely look better than tiles."

"It's about one meter by two or three meters in size, and it looks like a whole when it's stacked on the roof."

"Steel sheets are cheaper than tiles, lighter, and don't need to worry about the load-bearing of beams and columns when building a house, which can save a lot of money. They are also better looking than tiles, and can be guaranteed not to leak, so you don't need to pick up tiles to repair the roof. Do you think anyone will buy this kind of colored steel sheets?"

Li Muhua stared at Yang Liu with sharp eyes.

Yang Liu pondered for a moment, nodded and said, "Your idea is very interesting. Color steel tiles are indeed a good thing, but I have a question. If a thin layer of steel is placed on the roof, it will definitely make a noise when rain hits it."

"If you're inside the house, the sound will be louder than thunder. Such a house is simply uninhabitable."

Yang Liu directly questioned that her five years as a technician were not in vain.

Li Muhua pursed her lips and said, "There are two ways to solve this problem. One is to thicken the steel sheet. The sound is produced by vibration. As long as the steel sheet is thick enough that it will not vibrate due to rain, it will naturally not make any noise."

Yang Liu nodded and said, "That's one way, but the cost is a bit high and the weight advantage is gone."

Li Muhua nodded and said, "There is another way, which is to make meat-stuffed steamed buns with colored steel tiles, with a layer of iron sheet on the outside and foam inside. The foam fits well and not only does it eliminate noise, but it also reduces noise. The innermost layer has many possibilities, and can be made into various decorative panels, or you can directly stick a layer of the thinnest iron sheet on it."

Yang Liu nodded, looked at Li Muhua in surprise and said, "Sure, your colored steel tiles sound very reliable, you must have put a lot of thought into it."

"That's right!" Li Muhua said proudly, "My idea is not only reliable and profitable, but also beneficial to the country and the people."

"Just think about it, as long as we have colored steel tiles, we won't have to worry about the house leaking in the future, and we can save money on building a house. We can just find a place to prop up a few pieces of wood, and that will be a pavilion, which can also be used as a warehouse."

Li Muhua said that there is no need for application scenarios. Yang Liu is very clear about the target audience of this thing, and it is not an exaggeration to say that it benefits the country and the people.

So he simply said, "I have some experience with anti-rust paint. It's not difficult to design a rolling mill and a forming unit for the corrugated steel sheets you mentioned."

Li Muhua nodded and said, "The foam on the steel sheet is secondary. The anti-rust paint is the most important thing. It is difficult to ensure that the paint does not fall off in the wind, rain and sun for more than ten years, and the color must also look good."

"But that's fine. This is where we have a gap with the imitations. We'll make them stumble. We'll go to the Materials Department more often in the next two years and make sure we get the anti-rust paint thing done."

Li Muhua has already decided to give those imitative workshops a taste of their own medicine and let them know what science is.

Yang Liu also agreed with this. The anti-rust paint she had come into contact with before was usually very thick and would fall off at the slightest bump, let alone withstand more than ten years of wind and sun.

"You're right, but we both still have some time before graduation, so we can prepare all these first. Then we can open a factory and start production as soon as we graduate."

Li Muhua also agreed with this. This was his first time starting a business - he absolutely could not fail!

"Keep it confidential. If others know about this product, I'll have to think of other ideas."

"Don't worry!" Yang Liu nodded and agreed, and said proudly, "Look at where I worked before. From now on, I will be the one to set the confidentiality rules for our factory."

Thinking that Yang Liu had previously worked in a confidential unit, Li Muhua was even less worried that she would leak the news.

"Hey~~ After talking with you, I feel that marrying you is the best decision for me. It will make more money than running this crappy factory."

Li Muhua said with emotion: "He can take care of me at home and warm my bed, and when he goes out, he has to be my chief engineer without even paying me a salary."

Li Muhua couldn't help but grinning.

When Yang Liu heard this, her excitement instantly disappeared. She angrily dropped Li Muhua's arm and spat, "Get lost. You are so ungrateful."

"Hehe~~"

Li Muhua quickly hugged Yang Liu's arm and said, "I'm proud. Whose wife can be as good as you?"

"I am destined to marry a good wife. You have to admit that you are not as lucky as me. Who told you to marry a husband who does nothing?"

Seeing that Li Muhua was still being proud, Yang Liu was really impressed by him and stopped talking.

It was almost evening when we returned to the Li family——

In the afternoon, Li Haifu and Yang's father got along quite well. After knowing Yang's father's position, Li Haifu respected him even more.

This was the first time the two families met, so naturally he wanted to keep Yang's father to have a drink and chat.

Father Yang did not refuse, he also wanted to know more about the Li family's good intentions. After all, they would be Yang Liu's parents-in-law the next day and would live together for a long time.

Just as Yang Liu said, with Xu Yan and Li Yujie around, she didn't get involved in anything happening around the stove.

Li Muhua didn't say she could cook, so she just pretended not to know.

Soon the food was served. Seeing that Li Muhua actually placed a wine glass for him, Li Haifu couldn't help but ask in surprise: "You can drink after going to Green City?"

"You used to be a teetotaler."

"That's..." Li Muhua poured wine for Father Yang and said, "When my uncle and I meet, a thousand cups of wine are not enough for a good friend."

Father Yang nodded with a smile and said, "Mu Hua can drink quite well. A thousand cups is a bit exaggerated, but he can drink about four kilograms of local wine at most at one time. Ordinary people can only drink a little over one or two kilograms."

Li Haifu looked at Li Muhua in surprise. He didn't know Li Muhua could drink so much.

As soon as his thoughts turned, Li Haifu smiled and said, "It seems that your words are still effective. This kid has been disobedient since he was a child. No one can force him to do something he doesn't want to do."

"Muhua is good, quite to my taste."

After Yang's father praised Li Muhua, he said, "Your family has a good education, and all the children are promising. The second child is just not so good at studying, but he is willing to stay in the desert for his wife. This is a character that most people can't do."

"That's why I feel relieved to leave my daughter to your family. However, Yang Liu grew up in a military compound after all, and our family situation is also special. If she does anything wrong in the future, you and Mu Hua's mother will have to bear with her."

Father Yang raised his glass and uttered a few soft words. His daughter was about to get married and his mood was extremely complicated.

Li Haifu quickly picked up his glass and said, "Don't worry, Yang Liu is our biological daughter from now on, and Mu Hua is your biological son. There is no need to worry about it. It is our duty as parents."

They drank together.

Eating and drinking are mostly for intimacy, and let’s talk about the details of the day after tomorrow. There is no intention of not going home until you are drunk.

It was dim at night, and the six of them walked towards Xiaotangfang Hutong.

Although the yard is a bit old, it is kept clean.

The room was fully equipped with daily necessities, even the beds were made.

After saying goodbye to Yang Liu and his son, the four of them walked back.

Although the wind chilled his bones, Li Haifu's face was glowing with rosy red.

He was very happy to finally meet normal in-laws.
