[Moriarty of Worrying about the Country] Descartes Formula

Early in the morning, the girl moved a chair outside the shop to bask in the sun and made flowers in her hands. William was surrounded by some sad-faced tenant farmers while she was working. He was obviously a child, but standing in a group of adults, he was vaguely Looks like a backbone.

The agricultural land in this small town is also the territory of a nobleman. It is leased to various poor people to open up wasteland and plant, and then collect the rent every year. The annual harvest can only barely survive, but if there is any accident, the harvest will be affected, and the rent will not be paid. In such an end, if you meet that nobleman who is in a good mood, you may be able to handle the rent lightly. I will pay it together next year. If I am in a bad mood, I am afraid that the person who cannot pay the rent...

The girl just looked up and knew that there was probably something wrong with the farmland, but William should be able to solve it.After all, in the eyes of the girl, he is like a know-it-all, no problem can trouble him.

Out of William's reassurance, the girl was completely immersed in the handicraft, and she didn't withdraw from the state of concentration until her stomach protested. It's noon?William is not back yet.

The girl put down the things in her hands, and decided to go out with a little worry, "Louis, take a look at home, I will go to William." Louis is also a very well-behaved child, after knowing that he can't help his brother, he imitated William's Reading, after all, is often taught that learning is the easiest way to change your life.

"Okay, sister, be careful." Louis was also a little worried about the fact that his brother hadn't come back, and when he saw his sister decided to find someone, he immediately felt relieved.Although her sister looks very weak and weak, Louis feels that her sister is also very reliable sometimes, which is reassuring.

After asking a few people, the girl found the farmland on the edge of the town. William squatted on the ground, as if he was studying something, and next to him was a somewhat anxious tenant farmer, "How is it? Have you found the reason. But you The smartest child that everyone praises. He has read a lot of books, so he must be able to figure out a way better than us, right? Many crops have withered. If this continues, this year's harvest will be reduced by more than half, and if we can't pay the rent ” Probably thinking of the not-so-good consequences, the tenant farmer’s face twisted with a bit of fear and anger.

The girl walked over and stretched out her hand in front of William, "Uncle, William is trying to find a way, don't disturb him, besides, will bullying children make you feel very face?" "Sister?" William looked at the girl suspiciously .

Can the girl see that the tenant farmer is not in the right mood and has a vague intention to vent his anger? Will such words make William sad? After all, she is here to help.Fortunately, he was awakened by the girl, and the tenant farmer lost his momentum and became dejected.

The girl breathed a sigh of relief when she saw this, she is a war scum.

Then the girl squatted down and looked at William, "Did you find the reason?" William was holding a vegetable root that had turned yellow. The river over there, if there is a problem with the river, people usually have problems with drinking water, but this problem did not occur, so I am a little confused."

The girl got up and looked at the surrounding farmland. Suddenly, there was a deafening thunder, "It's going to rain again." The tenant farmers who had problems with the surrounding farmland yelled at the sky. The girl looked at the cloudy sky and frowned. , The half-closed eyes seemed to think of something.recent?It seems to be a bit rainy, and London is a place with serious air pollution.

Rain, earth, rotten roots. "Did sister think of something?" William looked curiously at the girl who seemed to have a clue, "acid rain." The girl spit out this word, and William thought about it in surprise, as if he had never heard of it.That is inevitable. The term acid rain was only proposed after 1872, and it is only 1865 now.

The girl explained, "To put it simply, acid rain is caused by the acidic substances released after fuel combustion, that is to say, air pollution and rainfall. Acid rain will destroy forests, corrode land, and reduce grain and crop production."

"Then what should we do? It rains every day and we can't stop the rain." The tenant farmers at the side heard the girl's explanation and roughly understood the cause of the rain. As for the term acid rain and the explanation behind it, their The amount of knowledge can't understand much.

The girl put her finger on her chin and thought for a second. The first reaction was naturally a vegetable greenhouse, but can products of this era do that?Let's find a substitute, the girl asked, "What kind of material is the cloth surface of the umbrella, can it be used in large quantities?"

Umbrellas are naturally a kind of rain protection, but, "That kind of material is only available to nobles." The tenant farmer dismissed the girl's idea, "Is that so." The girl thought about another method, "There must be thatch."

In the past, many houses used thatch as their roof. Although it is rare now, every household should have thatch. "That's true." Finally, when they heard something that could be used, the tenants responded quickly.

"That's fine. Just like fabricating a fence, put wooden stakes around the farmland and in each reclaimed line, and then put thatch on top to prevent the crops from being corroded by acid rain." As long as every piece of farmland is like this Even if it is heavy rain, the excess acid rain will slide down the thatch to the place outside the farmland, and it doesn't matter if the non-farmland is corroded.

"If it is covered like that, what will happen after the rain stops? Crops also need sunlight." "When the weather is fine, you can push the thatch to the sides along the way to fertilize and loosen the soil for the crops, let the sun shine on the crops, and wait for the rain It’s a little more troublesome to put it back on again, but this is the only way.” Limited by material constraints, the girl had no better way.

"Well, I can only try this way." Although the girl looks very ordinary and is not very old, she is just a little girl in the eyes of these middle-aged people who have been farming for decades, but what she revealed in her conversation That kind of self-confidence and temperament can't help but be convincing, not to mention that she saw the reason before William and could explain it. This has already made them decide to use a dead horse as a living horse doctor and try it once.

"If the effect is good, I will bring mature crops to come to thank you, Irene." One of the neighbors who is also near the book rental shop said first, and the others agreed, and the girl showed a calm smile "Then I will Take William home first." "Okay."

When everyone had a solution, they immediately implemented it. The girl held William who was still thinking about something, "What's wrong? What are you thinking about?"

"Sister? I haven't seen the word acid rain in the book at home." William, who is still very persistent in the words he has never seen before, the girl can't laugh or cry. It is lost, you have never seen it, but after this time, you should remember that acid rain is just a special situation caused by environmental pollution, it is not a big deal. William will learn a lot of powerful knowledge in the future , you will definitely become a great man who shocks the world."

"Great man." William was surprised by this boastful word, and his face turned red. However, with such a strict class division in this world, is it really possible for a child of a commoner to become a great man, or the path?This precocious child who has seen many forms of the world has already thought of many more complicated aspects that even adults don't know much about.

"Brother, you are back~" It was time for lunch, and Louis, who was already hungry, still insisted on waiting for his brother and sister to come back.

"Well, I'm back, Louis, you're hungry, I'll go prepare meals, wash my hands and sit and wait for a while." "I'll come too, sister." "No, let's chat with William." The girl left He went into the leaking kitchen and tossed about.

"Brother, is the problem solved?" Louis looked at him curiously, because it took a long time this time.

"Well, but this time, it was my sister who solved it." "Wow, my sister is really amazing." Louis didn't have the idea of ​​envy. In his heart, the older brother was the first and the older sister was the second. This time it was the older sister who solved it. The next problem will definitely be solved by my brother.

"Yeah, it's amazing." William showed a curious and inquiring smile. Would a child in an ordinary bookstore know so many things?If the girl knew what he was thinking, she would definitely say, do ordinary street children in the alleys know so much knowledge that adults don't know?

To be honest, the girl doesn't think that she can help William just once. William knows all kinds of knowledge, and the girl only knows some general knowledge, which is due to the nine-year compulsory education, but these are the routines for girls. Knowledge has not yet appeared in this time period.

What the girl said was not wrong. After a few days, a tenant farmer came to the shop to thank him, "Although the previous crops cannot be saved, at least the other crops have been saved. This harvest should barely be able to maintain the rent. Sorry. It’s okay, because I’m really tight, and I don’t have anything to thank, these are potato cakes made at home.” “It’s okay, thank you~ It’s just a small favor.” The girl took the cake that could serve as a meal. Thank you, I meditated a sentence Knowledge is power.

Fragmentary tenant farmers came to thank them, maybe some of them really had nothing to give, and the girl didn't care if they didn't come, these were already windfalls.Fortunately, in this weather, you can collect it for a few days and eat slowly without worrying about spoilage.

But since that incident, William seems to love talking to her?Girls should be happy. If it wasn't for the various issues discussed, why would you be one hundred thousand?I'm not an encyclopedia, the girl silently shouted in her heart, still maintaining a calm smile on the surface to answer the questions that could be answered.

At this time, I have to thank me for not dropping out of school and finishing college well. Otherwise, with so much miscellaneous knowledge, where would I know the answer.Thank you teacher! !

William: elegant smile
