Xi Yunfei, who came to the front yard, didn't know that Cui Ying'er's mentality had changed because of her unintentional actions.

As he grew up, except for Zu Weng, his father and his elder brother, Xi Yunfei was the fourth man to have a skin-loving relationship with her.

Moreover, it was Xi Yunfei who took the initiative to hold her hand, which seemed to Cui Ying'er a signal. Although it was a bit sudden, she did not resist. Instead, she felt happy and felt a sweet feeling like a deer bumping into her.

Cui Ying'er still has a deep impression of Xi Yunfei.

When Xi Yunfei invited her three uncles and nephews to have someone give her a cake.

Although it was just a small cake, Xi Yunfei's shadow had already shone deeply into Cui Ying'er's ignorant heart.

Next, Xi Yunfei's masterpieces were released, "Yu Meiren", "Yi Jian Mei" and "Taohua'an" are all Cui Ying'er's favorite poems and songs. Which girl doesn't want to have the dream of a talented man and a beautiful woman?

Finally, it was the instigation of the ninth uncle Cui Xian and his father Cui Shang during this period. Although Cui Ying'er was a little moved, the girl's reserve still made her dare not take the first step.

However, when Cui Ying'er knew that her father was also very satisfied with Xi Yunfei, she was actually very excited.

Cui Ying'er has been growing up in a big family like Cui since she was a child. Her married aunts often come back to complain about how bad their husbands' family were, and complain that the husband Zu Weng was not considerate and caring for her at the time.

Therefore, Cui Ying'er was also worried that she would become a victim of family interests like her aunts in the future.

However, she did not resist her father's choice this time, even though she knew that her father was obsessed with him for the benefit of the family, so she asked herself to please Xi Liu...

"Brother, stop asking, is it okay to have a meal first?"

Cui Ying'er was in a mess at this moment, and her mind was filled with the scene of Xi Yunfei leading her to walk.

Although the back is not very majestic, it is very reassuring.

Cui Yiye looked at his sister in confusion. He was the only one who could be called Langjun in Shuofang.

"Oh, okay, brother is here to have a meal."

Cui Yiye knew that something must have happened, otherwise his silly sister would not have shown such obsessive expressions. It’s just that it’s not the time to dig deep into these things. Compared to her sister’s affairs, it’s the most important thing to quickly make the generator set.

······

Front yard of Gewufang.

Li Fang didn't expect Xi Yunfei would come to inspect the work. The office was filled with various drawings, and there was not even a place to sit.

Xi Yunfei didn't mind either, so he found a chair himself, folded the sketches on it and placed them aside before sitting down.

“Have you eaten?”

Li Fang's eyes were congested, obviously because he didn't sleep well last night. He shook his head: "Not yet, I'll just eat a bowl of noodle cake to deal with. In the past, he used to have two meals a day, but now he's not used to changing three meals."

"That won't work."

Xi Yunfei said with some blame: "People are iron, and rice is steel. If I ask you to eat three meals, there will definitely be a principle of eating three meals."

"Yes, what Mr. Lang blames him." Li Fang nodded awkwardly.

Xi Yunfei sighed helplessly: "Forget it, you are older than me, and I'm too lazy to meddle in other people's business. Let's talk about the water pump. What's the progress now?"

When Li Fang heard this, his eyes lit up and he hurriedly took a drawing from the desk.

"Please look at it, this is the improved drawing, which is enough to cope with the depth of water drainage of thirty meters."

When talking about work, Li Fang's expression immediately changed by 180 degrees, and he excitedly explained his improved drawings.

After listening for a while, Xi Yunfei nodded with satisfaction: "Yes, the width of the water pump has been compressed and the depth has been lengthened. In theory, it can generate enough water pressure, but this has certain physical strength requirements for the power of pressing. Is it a normal woman and child not that strength?"

"Well……"

Li Fang was stunned when he heard this, and then thought for a while, then scratched his head awkwardly: "Theoretically, this is the case. If you want to extract more water, you also have certain strength requirements for the person pressing. This... it is a bit difficult to achieve both."

Seeing that he suddenly became unconfident, Xi Yunfei reached out and patted his shoulder with a funny look, and comforted him: "Okay, OK, this problem is actually easy to solve. At worst, it's just adding more people. If one person is not strong enough, then you can add another one."

Li Fang suddenly realized and said excitedly: "Yes, a woman's strength is not good, two are enough."

Xi Yunfei was really amused by him. As expected, all engineering men are straight men with cancer.

"Although this method is feasible, I suggest that you don't give up the original drawings. Create a set of both types of water pumps and let the customers choose them by themselves. If you want to draw water faster and have men at home, use an improved water pump. If you don't have men at home, you suggest that they use a water pump that draws water slowly, which is nothing more than taking more time."

"Haha, what the husband said."

Only then did Li Fang know Xi Yunfei's plan. He had considered this issue early in the morning and asked himself that he just wanted to take the postgraduate entrance examination and his management ability. After all, as the head of Gewufang, he also had performance appraisals.

Xi Yunfei's industry is owned by the manager. The funds Xi Yunfei injected into the Gewu Foundation were started capital. Next, all the awards from the foundation and the staff rewards of Gewufang were required to be earned by Li Fang himself.

So Li Fang couldn't wait to come up with a profitable product. Inspired by Xi Yunfei, a press-type pump came into being.

Many wealthy families in the Tang Dynasty dug wells, but they were not deep enough. And every time it rained, the well water would be polluted and become turbid.

Xi Yunfei's suggestion made Li Fang's eyes lit up. The press-type water pump is a brand new way to draw water. A simple press of the lever up and down can pump water from the ground more than ten meters deep.

Moreover, after the water well is installed with a pump pump, you can completely seal it, that is, you don’t have to worry about being contaminated or foreign objects falling into the water. After all, there are not many people who have been throwing wells in this era, and there are certain safety guarantees.

“It’s a pricing issue now.”

Xi Yunfei crossed his legs and asked, "Have you calculated the cost of building a set of water pumps?"

Li Fang nodded. He had really calculated this, and he went to the smelting workshop to ask Master Qiao Er.

Li Fang took a booklet from the table, opened it, and said, "Mr. Please see, this is the material cost. The improved water pump requires a total of 300 kilograms of iron, which is 15 jin of copper coins, and then the forging cost. My price is 500 jin... Finally, it takes a calculation to install a set of water pump well belts and at least 35 jin of copper coins. Do you think this price is OK?"

After hearing this, Xi Yunfei said with satisfaction: "Yes, just follow your price. You can also increase the price appropriately in the early stage. After all, it is a new matter that just came out. I believe that those rich people will pay, and then..."

"Okay." Li Fang hurriedly took a pen to record.

Xi Yunfei glanced at him with appreciation. Ma Zhou's habit was well implemented in various industries. After all, a good memory is not as good as a bad pen.

"Please tell me, Mr.
Chapter completed!
