Lin Yu took the drawn drawings and pointed out a few places for Zhou Gu to see.

"Add two baffles to this place, one on the left and one on the left, diagonally crossed, can you do it?"

After Lin Yu finished speaking, he looked up at Zhou Gu.

Zhou Gu looked at the drawings carefully, in the past, he helped the family make some small things, but he only followed the appearance of other people's homes, or pondered by himself, and he had never seen such formal drawings.

However, what Lin Yu asked for was not difficult, but he didn't understand it.

"Sister Lin, what's the use of your thing crossing over and over again?"

He remembered that Lin Yu had asked him to make a box before, which was tied to the car by Uncle Lin to collect money, and an oblique baffle was also added to it.

Lin Yu didn't hide it from him, "In this way, the copper can only go in and out." ”

Zhou Gu was stunned for a moment, with some doubt in his eyes.

Lin Yu didn't explain much when he saw this, "When it's done, won't you try it?" ”

Zhou Gu felt that it was right, and put away the drawings and returned them to Lin Yu.

"Okay, ten boxes, it will be ready in about two days, and I'll send it to you when it's ready."

Lin Yu looked at the drawings in his hand and was puzzled for a while, "Don't you have to bring this back?" ”

Zhou Gu touched his head and said, "I remember everything, no need to draw." ”

To be honest, if Lin Yu wasn't there to guide him, he wouldn't be able to understand it even if he gave him a picture.

Lin Yu thought about it, and also felt that the structure of this box was not complicated, and it was not difficult to remember, so it should be no problem.

After solving this problem, Lin Yu mentioned the mule cart again, Zhou Gu had already heard some news from his mother, and there were not many surprises when Lin Yu wanted to drive the mule cart to him.

Lin Yu asked him to drive the car back, get familiar with it in the past two days, and then go to the county seat with her in two days, and send people back.

I wanted to loosen my muscles, so I was going to go out, but I heard a knock on the door outside the hospital.

Mother Lin poked her head out of the house and saw Lin Yu standing in the courtyard, so she didn't care anymore and turned back to the house to do needlework.

Lin Yu shook his head helplessly, and could only resign himself to opening the door.

"Girl Lin, it's so nice that you're at home."

As soon as Lin Yufu opened the door, the people who came saw that it was her, and they were even more overjoyed.

Lin Yu took a step back, let people in, and said with a smile, "Why is your old man here?" ”

"Alas, you girl, I haven't been in the city for a few days, shouldn't I just come here?"

Dr. Zhang began to complain as soon as he entered the door.

Lin Yu rubbed the corners of her forehead a little helplessly, she had only been to the town for two or three days, how could it be as exaggerated as he said.

However, Lin Yu looked at him like this, so much so that he could guess a little bit of meaning.

invited people into the hall and was about to pour tea, but Dr. Zhang hurriedly stopped the people, "Girl, don't be busy, don't be busy, the old man didn't come to you to ask for tea." Let's get down to business. ”

Lin Yu saw that he was in such a hurry, so he had no choice but to sit down as he said.

"You've always come for that ointment, haven't you?"

Lin Yu went straight to the point, and Dr. Zhang smiled happily.

"You girl is smart, your old man has tried the ointment, and it works wonders. It is also recommended to a few patients with an old cough to try, they all said that after using it, the cough has been relieved a lot, and even the dull pain in the lungs has been greatly relieved, and it does have the effect of relieving cough and moistening the lungs. ”

Lin Yu was a little embarrassed to be praised.

She didn't expect that Dr. Zhang said to try, the action would be so fast.

He didn't care about trying it himself, and recommended it to his patients, so he was not afraid of smashing his own signboard at all.
