I Made 300000 a Year in Ancient Times

The busy farming season is over soon. Considering that I am paid monthly, it is not easy to really give the students a few months off. With the help of the enthusiastic villagers in the village, his family’s food is very fast. After collecting, a month later, a new semester will start.

For the children studying in Huajia Village School, Qu Qing is not only a teacher who teaches them to read and write, but also their idol.

In their eyes, Mr. is not only handsome, knowledgeable, and gentle, but also dares to think and do, and he will be able to do it if he says it.

He said that he wanted to invite talented people to teach them, but he actually invited talented people from all over the country; It was vigorous and praised by everyone, and even took this opportunity to take them to meet the county magistrate, and at the same time provided each of them with a pen and paper; In the past year, justice has been recovered, and the village tyrant Hua Daniu has honestly admitted to losing money...

What he said, some people would say that he was just whimsical at the beginning, but as he accomplished everything vigorously, the students no longer had any doubts about him.

Even if there are many other teachers in the school now, the status of Qu Qing, the so-called class teacher, in their hearts cannot be replaced. In the eyes of all students, Qu Qing is the biggest teacher in this school, the head of the school people.

Now that the teacher said that he would take them to make paper by himself, none of the 30 students in his class doubted that he could not do it.

But obviously the people in the village did not worship them as much. When many people heard the teacher said that they wanted to make paper, no one believed that Qu Qing could really do it.

"It's really whimsical. Let's forget about other trivial things. Papermaking is not so easy. If you can make paper by soaking a few bamboos, then everyone in the world can make paper, and I can make paper too hahaha."

The person who spoke was Hua Qiang's father. Hua Qiang showed off his teacher's deeds, but he didn't expect that his father would not give face at all, but laughed beside him.

Hua Qiang blushed immediately, and said loudly, "Father, just wait and see, our teacher can do anything, if he says he can make paper, he will definitely be able to make paper. When the time comes, the students in our class , including me, everyone will have free paper in the future!"

Hua Qiang's father clicked his tongue and said: "Who can brag, I also said that in ten years, I can increase the rice production in our field by ten times."

When they were talking, there was a sound of oops from the side. They looked out and found that Hua Qiang's mother in the kitchen was looking at the pile of ashes from the fire with distress and self-blame.

"What's the matter?" Hua Qiang hurried over with his father to have a look.

"Master, when I took the salt just now, I accidentally spilled more than half of the salt into the ashes, oh, what should I do, these salts are worth a lot of money." Hua Qiangniang looked at the ashes on the ground in distress , My heart hurts so badly.

Although salt is not very expensive, for those of them who don’t have much income and can’t even get enough to eat every year, the salt is a lot of money. At this time, a large handful of salt was sprinkled with plant ash Some of them were rescued with great difficulty, but they were already covered in ash, and more of them were almost fused together with plant ash.

Mother Hua distressedly took a small basin and put all the ashes into the basin. Knowing that there was no other way, she was reluctant to throw the salt away, but there was no remedy.

She looked at the pot of ashes distressedly, almost crying: "The salt is at least half a catty, how many eggs have to be sold to get it back, it's all my fault, my hands are like chicken feet, even a pack You can't even catch the salt."

Hua Qiang's father was also a little distressed: "Oh, it's really bad luck. If you fall, you will fall. What can you do now...Hey, Qiangzi, didn't you say that your teacher is omnipotent? You can ask Ask your teacher if he can get the salt out of the ashes."

"How is this possible!" Hua Qiang's eyes widened. His father was clearly trying to make things difficult for others, how to separate the salt that was almost as fine as ashes mixed together.

"You see, your husband also has things that you can't do. You can't even do this little thing, and you still make paper."

Hua Qiang looked unconvinced, and said loudly: "Who said our teacher can't do it? There will be a teacher's class in the afternoon, and I will ask in the afternoon. If our teacher can do it by then, Dad, you have to admit it sincerely." Our teacher is really good!"

"Okay, okay, I'm waiting for your good news here, don't touch the pot of ashes, my daughter-in-law, I want to see how this brat turns decay into magic today!"

Mother Hua looked at the childish father and son speechlessly, but she also held a glimmer of hope in her heart, Qu Qing knew so much, what if he really did it, after all, so much salt was thrown away like this, she I really can't bear it.

When it was time for class in the afternoon, Qu Qing was about to teach the songs he had prepared beforehand, when he saw the student Hua Qiang who was sitting below raised his hand, as if there was something wrong.

After listening to what happened, Qu Qing asked him to sit down, put the lesson plan in his hand on the podium, and said: "In this case, today's music class will be cancelled, and I will teach you a chemistry class... Um, what is chemistry? It’s really hard to tell at this moment, you just understand the lesson of refining things for the time being, the salt can be separated from the ashes, there is no problem at all.”

When Hua Qiang was making promises to his father, he actually didn't have any confidence in his heart, and he was afraid that he would make the teacher lose face, but now seeing his teacher confidently speaking, the big stone in his heart finally fell to the ground, and then he was beaming stand up.

Qu Qing discussed with Hua Qiang, and finally, after obtaining the consent of his parents, Qu Qing made an agreement with the students on the etiquette and agreement of going to other people's homes in advance. He walked to Hua Qiang's house in a mighty manner.

Huamu and Huafu wanted to warmly invite him to sit in the room, but Qu Qing waved his hands to thank them for their kindness: "It's fine for me and the children to go to class in the yard. I have to trouble you today."

Father Hua said, "Where is it?"

Afterwards, the husband and wife saw twenty or thirty students automatically standing in two rows according to height, each holding a handful of weeds picked on the road, and then Qu Qing said that everyone should sit down on the spot, All the children in the school neatly put the weeds on the ground and sat down on the ground like this.

Originally, they were worried about a bunch of children coming, how to prevent them from making trouble, they even locked the doors of the two rooms in advance, but they didn't expect that under Qu Qing's discipline, those troublemakers who were famous in the village were still obedient Sitting down, even with small movements in the hands, but anyway, sitting on the ground did not run around.

Seeing their son's well-behaved, straight back and earnest appearance, which is completely different from his appearance at home, Hua Qiang's parents felt very relieved, thinking that they could meet such a good teacher for free , it's really worth it.

Qu Qing first asked Hua's father and mother, who were standing and watching, to move out of the bench and sit down. Seeing the solemn atmosphere, Hua's mother whispered to her husband next to her a little excitedly: "We are going to class with Mr. today?"

Father Hua was also a little excited, but he still pretended to be reserved, but his constantly shaking legs betrayed his thoughts: "Yes."

Seeing that the preparations were about the same, Qu Qing clapped his hands, and the excitedly chattering children suddenly fell silent.

"Okay, let's start the class. What we are going to learn today is the characteristics of salt and the method of refining." Qu Qing brought the pot of salt ash in front of everyone.

"As you can see, the salt has fallen in, but it has been mixed with the ash. It is impossible to separate them with ordinary methods, but as long as we learn the characteristics of salt, we can easily separate the salt from it. , let’s think about it first, what’s the difference between salt and marl?”

"Taste? Salt is salty! Mud tastes awful."

"Salt is white! One grain at a time."

"Salt can be used for cooking, but gray cannot!"

Everyone expressed their opinions in a hurry, and Qu Qing deliberately guided them to think. Although they didn't answer the key points, at least they would think seriously. nodded.

"Actually, what everyone said is correct, but no one has thought of the difference we are going to use today," he said deliberately, "Salt is soluble in water, but mud and plant ash are not. Think about it." , a cup of hot water, put a little salt in it, will the water become salty after a while?"

"Seems to be."

"But teacher, I don't think you're right. Mud also dissolves in water, muddy water."

Qu Qing was not angry because of doubts, but nodded with a smile, and praised the students who dared to question him very much.

Even the flower mother next to her couldn't help but said, "Yes, but if you put mud in hot water, it will smell like mud after a while."

Father Hua patted her hand: "This is where you can talk nonsense? I'm sorry, sir, you can continue."

Qu Qing smiled: "It's okay, the question is correct, but here I want to explain that even if the dust falls into the water, it is not easy to pick it up at once, but this does not prove that it has melted in the water, it is different from salt Yes, salt is soluble in water, it is completely melted into the water, but the mud is different, the mud will sink to the bottom after a while, which is obviously different from the water, but the salt will not sink to the bottom, this is their difference.

Today we are going to use this different characteristic from mud to extract the salt, first add water to let the salt melt in the water, then filter the salt water and mud to separate, and finally dry the water in Ao to extract the salt again. The principle is like this, and now I will demonstrate it to everyone. "

As he spoke, he asked his father and mother to prepare hot water and a larger basin, and asked for a piece of cloth as a filter, and then lit a stove.

Some idle people in the village noticed the commotion here. They heard that they were coming to Hua Qiang's house for class, and immediately ran over to watch with some curiosity. The teacher Qu Qing has a lot of tricks every day, and they are all very interesting. Sometimes they wonder if he has taught the students to read and write. This is completely different from the school they know.

Qu Qing poured the salt ash into a large basin, and then poured it in with a pot of hot water: "This is our first step, let the hot water melt the salt first, here is a point, why not use cold water, this involves Another characteristic of salt is that the higher the temperature, the faster it melts, so if it is cold water, it will be slower. There is no difference in this experiment. If you are interested, you can experiment with hot and cold water at home. "

The onlookers immediately knew that it was salt and mud mixed together, and they wanted to extract it. This is interesting, and they were all very curious about how this gentleman would do it.

"In order to help melt in the middle, stir with a wooden stick to confirm that all the salt has melted before starting the next step. Oh yes, here is another characteristic of salt. The concentration of the solution is equal everywhere. For example, if you drink water with salt, Stir well, and after all the salt has melted, the water in every place will be equally salty."

"Now the salt has melted, and now we wait for the mud to settle to the bottom of the basin, and then pour the water into another basin through the strainer, which is used to filter the mud."

He talked and did it without panic at all. He seemed to be in order. After waiting for ten minutes, the mud settled. He asked the help of two adults who were watching to lift up the basin carefully, and filtered the salt water to the other side with a filter cloth. inside a basin.

"Now we have clean salt water, and the marl is real marl, which can be thrown away. Now we start boiling the salt."

As he said that, he put a small pot on the stove next to him, scooped water into the pot and started cooking, and kept gathering firewood during the process.

This is a relatively boring process, but soon, when a pot of water is about to dry, everyone sees with wide eyes that salt crystals actually appear in it! As the salt water becomes less and less, the salt in the pot There are more and more.

Seeing the shocked expressions of the people around him, Qu Qing's expression remained calm: "Part of the sea water is extracted from the sea, but people at the seaside do not use firewood to boil it, but to obtain salt by drying the sea water, but drying it from the sea The salt produced cannot be eaten directly, it has to be processed, I don’t know the details, so I won’t talk about it, and in addition, making salt without permission is against the law, so please don’t do it.”

After saying this, the surrounding villagers, including the students, all laughed: "We are going to make salt there. I don't know how many miles away from the sea here."

"I'm just joking." After Qu Qing finished speaking, he laughed along with everyone else.

Seeing that the sun was about the same, Qu Qing saw that everyone had learned, so he asked the students to take what they had brought and go home after school. Hua Qiang's parents said that they could do it by themselves after seeing this, and invited him Stay for dinner.

Qu Qing declined, and then instructed: "In fact, the water has been boiled like this all the time, and when it is boiled dry, all the salt will come out. Although a little bit is lost in the wet mud, those can be ignored. Thank you very much for today." You took care of my children."

After some courtesies, Qu Qing said goodbye and went home for dinner.

Father Hua looked at the back of Qu Qing leaving, and reached out to pat the back of Hua Qiang's head: "Son, your teacher is really good, you have to follow along and study hard, it's not in vain for me to study for you."

Seeing the admiration in his father's eyes, Hua Qiang immediately puffed up his chest proudly: "Of course."

Father Hua soon went to brag to his neighbors, proud of his son, and said: "Hey, sometimes I really envy these brats, if I was born ten years later, I would like to sit in school and study, you Not to mention, listening to this lesson is quite interesting, and I will master it as soon as I learn it."

The neighbors also nodded in agreement, talked for a long time, and finally sighed sincerely: "It's so good to study."

The author has something to say: These chapters are probably idle and trivial matters, but the main point is that the protagonist himself is not aware that some of the thoughts he spreads have subtly affected the people around him.

I remember that it was mentioned in "A Brief History of Mankind" or somewhere why there is such a huge difference in the modern development of China and the West. There is probably a point of view that the mainstream thinking in the West dares to admit its ignorance, so it dares to pursue it even more. Truth, which is also an ideological basis of the subsequent scientific and technological revolution.

The protagonist is definitely unable to bring about a technological revolution. Many things are too difficult. It is impossible for ordinary people to build steam engines in a world without any industrial foundation. However, he can spread his ideas of pursuing science to ancient times. In fact, this In my opinion, it has always been a very remarkable thing~
