No matter if you are a human or an immortal, you can still farm for me after traveling through time!

A family of ten or twenty people crammed into the family, and the small courtyard was so packed that it was impossible to spread their bodies. Ji Qingyue had to remove the long door of the bedroom to connect the courtyard with the bedroom space.

Now there is finally room to accommodate so many people, but the embarrassing thing is that there are only four chairs in the house, which is obviously not enough. When Ji Qingyue demolished the door, Li Yu cleverly ran to the next door and borrowed several benches.

Ji Qingyue had made many pottery cups and bowls before, and now he used them to entertain guests. The two of them carried copper pots and poured water for the shopkeepers.

Everyone sat down, holding pottery cups and pottery bowls, and saw that Ji Qingyue had just moved to a new home. He had not had time to add furniture or anything else, and the stove in the corner of the yard was also newly built.

After greeting everyone, Ji Qingyue asked Li Yu to close the door, and he stood on the steps in front of the bedroom door, surrounded by the shopkeepers and stewards.

First, announce the first question.

"There is a dry well in a courtyard. The well is seven feet deep. There is a snail at the bottom of the well. It climbs up 3 feet during the day and slides down 2 feet while sleeping at night. How many days does it take for this snail to climb to the mouth of the well?"

As soon as Ji Qingyue finished speaking, someone confidently opened his mouth to answer: "This is not easy!! Seven days!!"

Apparently some people had already come up with this answer. After the first person answered, they stood up and confirmed that the answer was "seven days". Some people secretly breathed a sigh of relief, as if they had other answers.

"Others can whisper to me and Yu Lang." Ji Qingyue gave Li Yu a look, and the two of them quickly shuttled through the crowd, listening to other people's answers and recording them on paper.

At this time, the steward who was the first to answer the question seemed to have noticed the trap in the question, or heard a different answer from the other side, and was surprised: "Ah! Wrong!!"

At the same time, some people also realized that this question is not very difficult, but it is easy to lead people astray. If you ask questions quickly and answer quickly, it is easy to get into trouble and answer incorrectly.

After Ji Qingyue and Li Yu checked their answers, they announced in public: "Congratulations to the eleven shopkeepers and managers who answered 'five days'. Your answer is correct."

Some people shook their heads and sighed, while others quietly raised their heads and were quietly proud.

"The first question is just for you to warm up. Next is the second question. Please listen to the question: An old farmer brought a hundred catties of green onions to the county to sell. The price was ten cents per catty. A man came up and asked the old farmer about the price, 'One hundred catties. Can the green onions be sold, including fifty pounds of green onions, fifty pounds of green onions white, seven cents of white green onions and three cents of green onions? The old farmer answered 'yes'. I asked why the green onions that should have been sold for one tael are now only sold for five hundred cents."

With the experience of the first question, no one dared to answer it first, but thought about it slowly in their hearts.

Why is this?

Ji Qingyue waited for a while: "Anyone who has the answer, please follow me into the room. If one person answers the correct answer and tells the reason in detail, the answer to this question will be stopped."

As soon as the words fell, two people stood up in a hurry. When the others saw it, they became anxious, fearing that they would answer the question first, regardless of whether it was correct or not, so they also stood up and shouted to answer the question.

Ji Qingyue asked them to be calm and queue up one by one to follow him in.

Most of them knew what the key was, but they just couldn't organize their words and couldn't speak in front of Ji Qingyue.

The people at the back stood at the door and kept putting pressure on the people who answered the questions, saying: "If you can't answer the question, just come out and wait! I'm hemming and hawing for so long!!"

Under waves of urging, the people in front became anxious and ashamed. They sighed heavily and turned around to go out. They even glared at the people who were making noises when they passed by.

The two shopkeepers who were rushing to answer the question obviously did not understand the question requirements, and the answer was how to get the final figure of 500 copies sold.

What Ji Qingyue wants is the reason, not the solution.

Five-seven-thirty-five, five-thirty-five, three hundred fifty cents of green and one hundred fifty cents of green onion, we get five hundred cents. Everyone knows this, but why?

Why did Onion, which should have earned one tael, only get 500 wen? Where did the other part of 500 Wen go?

Within about five minutes, two more stewards walked out of the room, shaking their heads.

The person who answers the questions first does not necessarily have an advantage. What matters is the flexibility of "brain teasers".

The fifth-ranked shopkeeper "coughed" twice and walked up to Ji Qingyue: "The price of green onions is ten cents, while the prices of white and green onions are seven cents and three cents respectively. It looks like ten cents, but in fact they are different. The price dropped by three to seven cents, but the weight remained the same, but the price dropped. This is why the old farmer lost five hundred cents."

Ji Qingyue smiled, feeling that the shopkeeper was a little cautious when he answered, as if he was being poked into the center of things, and became embarrassed when facing his faint smile.

The shopkeeper then explained: "I have used this method to buy fresh fish before. I bought the fish head and body separately. I was sued by the fish merchant and warned by the owner, so I didn't dare to play this little trick again, Yue Lang. You can rest assured.”

It turns out that I have done this kind of thing.

Sure enough, experience comes from life.

Now that someone had answered the question, Ji Qingyue officially announced that the shopkeeper had answered the question correctly.

The others breathed a sigh of relief when they saw that this person answered correctly.

Ji Qingyue glanced at the shopkeeper. He was the first to answer the first question but got the wrong answer. No wonder the others were relieved. As long as the person who didn't answer the first question correctly answered the second question correctly, They can still compete for victory on the third question.

Twelve of the fifteen people present scored one point. Obviously, the first two questions did not stump them.

Next is the third question.

"The third question is the same as the second question. Anyone who can figure out the answer can come to the room to answer it. There is no time limit or order limit for this question, but you have only one chance to answer the question, so please answer carefully."

When Ji Qingyue said this, everyone became a little nervous, but after hearing that there was no time limit and no need to queue, they all felt relieved.

"The last question. There are three students staying together in the inn. There is only one room left in the hotel, which costs thirty cash. The three of them decided to pay ten cash each to book a guest room. The waiter accepted the money and informed the shopkeeper. The shopkeeper wanted to stay here. The student was a student and wanted to take care of him, so he decided to only charge twenty-five cents for the study, and asked the waiter to return five cents. The waiter got greedy on the way to return the money, so he paid two cents, and finally only returned three cents. Because Three cents were returned, that is, each student only spent nine cents on lodging, the three of them spent a total of twenty-seven cents, and Xiao Ermo spent two cents. The total of the two was only twenty-nine cents. I asked why one penny disappeared. ?”

As soon as the question came out, everyone was in an uproar.

The people present were all arithmetic experts. The abacus was clicking, and they had never seen how much money they had. They had to go through the daily running accounts of the store. How could they not be able to calculate such a simple number? !

Three-nine-twenty-seven, Xiaoermei has two Wen, only twenty-nine Wen. But the three students were clearly given thirty cash when they checked in. Where did the other one go? !

The courtyard fell into silence after Ji Qingyue finished reading the questions. No one was rushing to answer the questions first, but brainstorming began.

The shopkeeper, who came with the accountant, took the accountant aside and discussed quietly. The discussion went back and forth, but the two of them looked at each other.

That's right, after all that, it's twenty-nine cents!

Li Yu himself was confused. He didn't expect the answer and was not depressed. Instead, he looked at Ji Qingyue without blinking, his eyes full of admiration.

Ji Qingyue stood in the room and waited, without urging them, but letting them think quietly.

The door of the house was closed at the beginning of the battle. It was impossible to ask for help from the outside. They could only rely on themselves and desperately come up with answers.

After answering the first two questions, everyone figured out Ji Qingyue’s idea of ​​​​questioning. The key is not arithmetic, but speaking skills.

But the difficulty of the questions gradually increases, and the difficulty of this question is more than a little more difficult than the previous two.

After a cup of tea, no one wanted to enter the room to answer the question.

At this time, someone asked: "If we communicate with each other, will our answers still be effective?"

Ji Qingyue made a "please" gesture. He didn't want to have any grudges with these people. Discussion and answering had a role. It could secretly reduce everyone's complaints. He had already lowered his requirements in this way. Regardless of whether he could answer correctly or not, resentment could not Facing him again.

Anyway, you can supply one vegetable or several vegetables. If you really want to expand the planting in the end, then raise the price.

Ji Qingyue drafted the contents of the contract in his mind. After two cups of tea, the people in the yard no longer fought alone, but became a situation where everyone gathered together to discuss.

Obviously, everyone knew that each other was a competitor, and the discussions were conducted in a measured and measured manner. Many people listened, but few spoke. Instead, it was the three shopkeepers who were no longer competitive and were eliminated first, who were talking eloquently.

Among the crowd, a shopkeeper came with a special mission. After silently memorizing the topic, he began to think about it leisurely. He came with the accountant. The two of them thought about it and seemed to have some inspiration, but they couldn't grasp it.

While everyone was discussing, Ji Qingyue was also thinking about his own affairs.

The vegetables in the painting have matured, and the magical land is accelerating a bit too fast. The vegetables must be picked the day after tomorrow at the latest, otherwise they will miss the best period of consumption and rush to the "old age".

Among the vegetables planted this time, Chinese cabbage accounts for the most weight. Several hundred Chinese cabbages can weigh up to 800 kilograms. There are also eggplants, cowpeas, lettuce and cucumbers. These are all vegetables that are edible, and each harvest has a weight of Three to four hundred kilograms, plus leeks, spinach, celery and broad beans, it easily exceeds two thousand kilograms.

These are the harvest amounts without scientifically planting two vegetable fields. If we really plan, it is not impossible to exceed 3,000 kilograms.

But the most important thing is how to serve these dishes without suspicion.

It is definitely impossible to take it out directly at home. The neighbors are not blind. How can it be possible to grow so many vegetables in such a small yard, so Ji Qingyue plans to choose the trading location outside the city.

Delivering goods outside the city does not require him to worry about inspections in the city. He can also use the excuse "outside the city" to conceal the origin of these vegetables. Anyway, when asked, they are grown in the mountains.

Which mountain?

This is confidential and I can’t tell you!

It's in a mountain that Li Yu doesn't even know about.

The more Ji Qing thought about it, the more time passed for another cup of tea.

One cup of tea is equal to about ten minutes, three cups of tea is equal to half an hour, and the drumbeat of time comes from the bell and drum tower in the county.

Ji Qingyue saw that the time was almost up and had to ask: "But someone has come up with an answer and wants to answer it?"

He said this, but no one stood up.

To understand this question is to understand it thoroughly, and there is no half-knowledge of the solution.

This is the reason why no one has come up to answer the question so far. They can't guess blindly. They are thinking about their own guessing ideas. They are amused by their own guessing ideas without even thinking about answering.

Know nothing.

Saying it would only make it appear that all the hard work of more than ten years was wasted, so it would be better not to say anything.

As a well-established restaurant owner in Shandan, he still needs to be proud.

Since I can't figure it out arithmetic, I can only start from the logic of Ji Qingyue's question.

These questions all have traps that make it easy for people to fall into them. The logic in the text goes around and around, and the parts that are most inconsistent with the rules are traps.

For arithmetic problems, the most likely place to confuse people and create loopholes is "over-counting" or "under-counting".

Are there any repeated calculations or omissions in this question?

The customer bid thirty cents, but the shopkeeper only accepted twenty-five cents. This was just a sure thing and there was no room for error. It is also true that three of the five articles were returned, and Xiao Ermei wrote two.

……

It turned out to be the case.

The shopkeeper suddenly thought about it, slapped his thigh, threw his head back and laughed, looking even happier than making money, and shouted: "So that's it!! It's like this!! Yue Lang, come and listen, am I right? Got it!!”

The shopkeeper walked into the room with his head held high under everyone's gaze. Because the door panel was removed, everyone could clearly see what was going on in the room. The shopkeeper who answered the question approached Ji Qingyue, pointing in his hand while answering softly, with a look on his face. Confidence does not seem to be fake.

The most depressing thing is that Ji Qingyue actually nodded and smiled along with the shopkeeper's answers. Obviously, the shopkeeper said the correct answer! !

Rather than being anxious, they had almost forgotten that the purpose of their trip was to buy groceries, and now they wanted to know the answer even more! !

Urgent! Urgent! I’m so anxious that I’m scratching my head! !

Finally, after the shopkeeper who answered the question finished his answer, he knew from Ji Qingyue's expression that he had answered the question correctly. He grinned happily as if he had received a promotion and a salary increase.

Ji Qingyue was also very excited. Finally someone answered the question correctly. He finally found his employer!

He reached out his hand excitedly, wanting to shake hands with the shopkeeper, but suddenly realized that there was no handshake here, so he could only retract his hand and clasped his fists to express congratulations.

"Is there anyone else here to answer questions?" He looked at the shopkeeper walking out of the room with his head held high. This person was a big shopkeeper named Tai'an Restaurant.

The remaining people finally made up their minds, regardless of whether they had figured out the correct answer or not, they would step forward to answer the question.

Facts have proved that sometimes it is impossible to guess the question correctly by guessing, and it is impossible to directly guess the proof of a mathematical question.

For questions such as proving the congruence of two triangles and the moving point of a function, if the answer can be written by guessing, Ji Qingyue would simply write "respect" in capital letters.

All the shopkeepers came forward to answer the questions, but there was always someone who couldn't explain the key. In the end, only the Tai'an Tower shopkeeper could answer the last question completely.
