After receiving an affirmative answer, Lu Caiqing happily showed off to Lin Huaijin: "Only you can't get used to it, but it doesn't matter, you don't live often, you can go back to your city if you can't get used to it." ”

Song Ziyu looked at his little daughter-in-law dotingly, and he couldn't help but give face to the guests, so he hurriedly stopped: "Little daughter-in-law! After all, Boss Lin is a guest, don't quarrel. ”

Lu Caiqing nodded when he heard this, and said, "I almost forgot to get down to business, you learn by yourself, I still have something to do." ”

After finishing speaking, she picked up the paper and pen by herself and drew it, Song Ziyu knew what strange things her little head was thinking, and she couldn't understand it, anyway, she would explain it to herself after she drew it, so it was better to practice the arithmetic while she was doing it now.

Lu Caiqing took the pen and pondered for a while, and then carefully drew the structural diagram of the foreign well, commonly known as the pressurized water well, on the paper.

Pressurized water well is a kind of tool that sucks groundwater to the ground, the well head is seventy or eighty centimeters high from the ground, closely connected with the vertical pipe inserted into the ground with screws, the front is the outlet pipe mouth, the tail is the pressure handle that is connected with the well core, the pressure handle is sixty or seventy centimeters long, there is a piece of water diversion skin in the middle of the well core, and the groundwater is sucked up by the force of this water diversion skin and the well core.

After the painting was completed, I looked at it carefully, and I didn't know if the parts of such a pressurized water well could be made in the blacksmith shop in this city.

When he was worried, he raised his eyes and saw Lin Huaijin, and he happened to be looking up at himself, so he asked, "Brother Lin, aren't you in the county town and have a wide range of popularity?" Then I want you to do me a favor and see if you know if the blacksmith shop in the county seat can create these things that I drew on the map? ”

"What's that? Show me? In addition, he looked at it for a long time, but he did not see what he was drawing. So he asked, "Forgive me for not seeing what this thing is?" Can you explain it to me? ”

Lu Caiqing knew that he had definitely not seen it, so he begged someone to ask for it, so he planned to explain this pressurized water well to him, and Lu Caiqing also called the three brothers to listen to it by the way.

To put it simply, the principle of negative pressure is used, but in fact, it mainly relies on the well core and the water diversion skin. When the handle is pressed down, a vacuum is formed inside the cylinder, the water is sucked up, and when it is lifted up, the water diversion skin is lifted up and automatically opened, and the water gushes out from the upper valve, and so on, the water is drawn up.

Song Ziyu looked at Lu Caiqing in surprise, not because she had researched this thing called Yangjing, but because she saw that she was working hard to carry water and felt sorry for herself, she was happy and had some self-blame at the same time.

He suddenly felt that he had wronged his little daughter-in-law, and when he saw Lin Huaijin looking at his little daughter-in-law differently, he ate dry vinegar, saying that his little daughter-in-law was too good, which caused the favor of the opposite sex, and she had nothing to do with half a dime, and he was still unreasonable, and the little daughter-in-law's heart has always been on him, and he is still messing around with others, and he doesn't cherish her at all, he is really stupid and stupid.

Thinking of this, he secretly decided that he must fight for his little daughter-in-law, not let her worry about herself, study hard to keep up with her little daughter-in-law's thoughts, and make progress together, and let those who admire her daughter-in-law retreat.

Lin Huaijin looked at the little woman in front of her, she came for two days, and said that she was a smart and cultured girl, but she didn't expect to be able to drum up such a great project in her head, although she didn't know what the results were, but she felt feasible.

Looking down at the drawings, the structure was clear, even Ziwu and Zifei, who had no culture, were envious of this thing, and when Lin Huaijin raised his head again, he saw Song Ziyu holding Lu Caiqing's hand and saying words of thanks.

I suddenly remembered what Lu Caiqing promised him yesterday, and I saw that he worked hard to carry water, so he designed this thing called Yangjing. I am envious, why don't I have a woman who treats me sincerely, who is as smart and clever as her, and who is honest and considerate of herself?

Lin Huaijin was envious and a little jealous at the same time, if Cai Qing was divorced by him, how good it would be, then he would marry her immediately, whether she was a widow or someone who was abandoned, he didn't care, I really hoped that Song Ziyu didn't know gold and jade, and took the initiative to give up, but this hope was a little too late.

Lin Huaijin looked at the scene of the two people in front of him, you and me, and knew that this man had spoiled this woman as a treasure, and if he wanted him to give up, it was probably impossible, wasn't he Lin Huaijin with vicious means? There is nothing difficult for herself in Jeju City, but if she finds out that she is calculating Song Ziyu, then it is estimated that it will be difficult to be friends with her in this life.

Lin Huaijin, Lin Huaijin, you who are not afraid of heaven and earth, the living king of Jeju City! Today, I was impressed by a weak woman, and I was afraid of losing my friends with her, and it seemed that I was watching her happy in this life.

"Brother Lin......!" Lin Huaijin is still melancholy about God's injustice to herself, is it possible that she is smooth sailing in her career, but is she blank in love? Why can't God be an adult and make himself a good harvest in love and career?

At this time, Lu Caiqing next to him shook him and said, "Brother Lin! You're talking! Is there such a blacksmith shop? ”

Lin Huaijin came to his senses at this time, and thought for a long time before saying: "Yes, yes, but although I understand the thing you said, the specific details still have to be explained by you personally!" ”

Lin Huaijin looked at Lu Caiqing with a weak heart, thinking that she just wanted to stay with her for a while longer, so that she would have to let her enter the county seat again, so that she could stay with her for a few more days.

Where did Lu Caiqing know his careful thoughts, he really thought that he didn't understand, thinking that too, only by elaborating on it himself, can he make things meet his own requirements.

"Oh well! Take advantage of the fact that there is no farm work now, and I will go back to the county seat with you to have a look, so as not to find time for yourself. Lu Caiqing said seriously.

Song Ziyu heard this and hurriedly stopped: "Little daughter-in-law! Why don't we go back in two days, Boss Lin is not in a hurry to leave, why don't we do the preliminary work of digging a foreign well at home first? ”

Lu Caiqing thought he was jealous again, but seeing that his sincere eyes did not dodge, he asked, "Why?" Brother Song, this well should be drilled sooner rather than later, and if it is built one day earlier, it will take less effort for one day, I really see that it is very hard for you to carry water so far. ”

"Yes! Eldest brother! Build it early, and we use it a day earlier. Song Ziwu said anxiously.

Song Ziyu was in a hurry, and said hesitantly: "Don't worry, just wait two or three days!" Little daughter-in-law...... The little daughter-in-law is inconvenient and afraid of being tired these days! ”

When Lu Caiqing heard this, he suddenly came to his senses, and he didn't know if the men in front of him understood or not, so he ran back to the room shyly.
