The business of my aunt's breakfast shop is getting better and better day by day, which makes my aunt very busy and happy, and the whole person is more energetic than before.

A bowl of preserved egg porridge and a penny of fried dough sticks can be eaten by almost everyone in this Yuzhou City, and for the aunt, there are two layers of profit in every penny.

Wu Zheng suggested that the porridge should be boiled thinner and the fritters should be fried, so that the profit can reach at least four layers.

But as soon as this was raised, it was counted down by the honest aunt, saying that it was too black-hearted, and that it would be looked down upon by the neighbors in the street, and that the family was not short of that one or two layers of profits now, and the reason was that since there was this breakfast shop, the copper money I got every day was five times that of washing clothes before.

And in addition to being busy for a while in the morning, she has a lot of time to do other things in the afternoon, which is the day she dreamed of in her previous dreams for the aunt, so she has eaten enough.

Wu Zheng was a little unconvinced, he said that boiling the porridge a little thinner does not mean that it can show the shadow of people from now on, but a little less, don't you see that people eat three pennies now? I just want to make the Sanwen line just enough for people to eat, and at the same time, it can also reduce the waste of children.

Wu Zheng felt that his proposal was very reasonable! But the grandmother on the side listened, but helped the aunt speak, saying that our family pays attention to honesty in doing business, and our old Wu family doesn't do the kind of things that make people pinch their backbones.

Wu Zheng wanted to persuade again, but he was slapped by his grandmother on the back of the head, forget what they like to do! Anyway, this shop is also for my aunt, as long as she can see her happy, she can sell it as much as she wants.

Since then, my grandmother has not persuaded herself to study more, but instead told herself to be a good person.

Are you greedy? Wu Zheng didn't think so, but his grandmother's words were not disobedient, so he had to hide in the kitchen alone to make a stethoscope.

Use the dehydrated duck intestines to make the ears made of bamboo and the probe up, and then use the wire to tie the interface tightly, and then bring the earthen stethoscope on his body to try, the effect is not bad, at least better than he expected, of course, if the ears and the probe can be made of copper, the effect may be better, but that is the matter of the old man Huang, if he is always happy, even if he is a gold.

Took the stethoscope and went straight to the old man Huang's medical hall, as soon as he entered the medical hall, fortunately the sun came out today, the brazier in the house was not as hot as that day, and people would only feel warm when they walked in, not like last time they just wanted to smoke people out.

Old man Huang was sitting behind the table, at this time he was checking the pulse of a fat rich man dressed in Yanju clothes, and the old man looked very intoxicated with his eyes closed and twisting his beard.

I just don't understand, probe the pulse and what's there to be intoxicated with.

Wu Zheng walked over and probably blocked the old man's light, the old man opened his eyes and glanced at Wu Zheng, then ended the diagnosis, wrote the prescription while explaining the doctor's order to the fat rich man.

However, seeing that the fat rich man picked up the prescription and glanced at it, he hurriedly thanked Old Man Huang repeatedly.

Old Man Huang didn't seem to like this person's compliment, and waved his hand to tell him to hurry up and grab the medicine.

After Wu Zheng watched the fat rich man come out of the inner hall, he came over and said, "Old man, this flower willow can also take the pulse out?" ”

Old Man Huang's eyes widened, and he said angrily: "How do you kid know that he got a flower willow?" ”

Wu Zheng pointed to his eyes and said with a smile: "Look and hear, the kid just sees with a pair of discerning eyes!" ”

Old Man Huang smiled: "Your kid's eyes are good, you can see it just now?" Shouldn't you have learned to look for flowers and ask willows these days! ”

"Old man, you are too underestimated to be a boy, and that kind of cheap brother-in-law kid is not willing to do it."

Old Man Huang smiled slightly, and pointed to the person who grabbed the medicine in the outer hall: "Since you kid said that you can see it, then what kind of disease did you say that person had, if you can also see it, the old man will admit that you have a pair of discerning eyes." ”

Wu Zhengnian glanced at it and said with a smile: "Is there any substantial benefit to saying it?" ”

"It's not good, I love to say it."

"Then I won't talk about it, by the way, this is our old Wu family's auscultation artifact, the kid brought it to you today."

After Wu Zheng finished speaking, he put the earthen stethoscope on Master Huang's table from behind him.

If you want to say that the stethoscope made of bamboo and duck intestines on this table is an artifact, unless you are blind, you have to work without work, you have to sell without buying it, and you can smell a fishy smell of duck intestines when you pick it up and smell it.

But the old man was rarely not angry, because with his old man's wisdom he understood the beauty of the stethoscope just by looking at it.

It's really simple to say, and in the eyes of Old Man Huang, it's even more simple and outrageous, but it's such a simple and outrageous thing that I never thought of it.

Old Man Huang picked up the stethoscope and said, "Is this thing easy to use?" ”

Although the old man didn't say that this thing was an artifact, he could still hear it from the tone of his voice, and he understood it, at least he had already concluded that this thing must be useful, and the reason why he asked was just to get Wu Zheng's certainty.

Wu Zheng said with a smile: "The old man is worthy of being an expert, and this doctor's thing can be divided into three points as long as he looks at it." Originally, the kid was going to get you a copper, and the effect would definitely be better. But if your old man is in a hurry, you can only use a bamboo to fill the number, as for whether it is not good or not, your old man will know if you try it. ”

"Then what are you waiting for, why don't you sit down quickly."

"Uh...... All right! ”

The old man put on a stethoscope and tried it on Wu Zheng's chest and back a few times, and couldn't help but nod and said: "This thing is really easy to use, how could the old man not expect such a simple object to come back again!" ”

"Hey, I said old man, you shouldn't be going back!"

Old Man Huang glared at Wu Zheng and said, "Although my old man is poor, he is not so bad that he will not admit what he has said. Chai Hu ......"

Chai Hu, who was grabbing medicine in the outer hall, immediately ran over, leaned over and said respectfully: "Teacher, you called me?" ”

Old Man Huang took out the key and said, "Go and get the treasure box for the teacher." ”

Chai Hu didn't leave immediately, but glanced at the stethoscope in Old Man Huang's hand, and the stethoscope made by Wu Zheng was supposed to be used to fool children, but he asked his teacher to ask him for fifty taels of gold, which made Chai Hu feel worthless for his teacher.

"Teacher, can't you see it? He is deceiving people, not to mention fifty taels of gold for the goods he made, even the disciples of fifty Wen think it is expensive, if he dares to find trouble, we will report to the official, don't be afraid of him. ”

Hearing Chai Hu's words, Old Man Huang couldn't help but sigh: "This kid did have a pair of clumsy hands, and making such a simple thing actually made him make such three flat and four unround." But what you want to buy for the teacher is not this rag goods, but the truth contained in this rag goods, as far as this truth is concerned, let alone fifty taels, even if it is five hundred taels, it is worth it. ”

"Five hundred taels!" Chai Hu's mouth was wide open enough to reach into a fist.

Wu Zheng smiled: "Don't be so surprised, the layman looks at the excitement, and the insider looks at the doorway." If you can't understand it, it's because you're an apprentice, and if you can understand it, then you'll not be a master. ”
