At dinner time, Xu's mother strongly "criticized" her son's behavior of spending a lot of money to buy water.

"It's a waste of money, and the water at home is not enough."

For buying water, Xu's mother has no objection, but the price is too much, and this water is not made of gold, it is outrageous, and it is outrageous.

"Mom, some time ago, didn't you still complain about the lack of water? There are so many people in our family, and such a little water every day, let alone taking a bath, it may not be enough to wash your face. Xu Dong persuaded.

"Then you shouldn't sign a contract that long for three years, maybe in a few days, the water supply time will change back?"

Xu Dong took a sip of watermelon juice: "Impossible, once the plant factory is put into use, it is impossible to shut down casually, even if it is water for residents, they have to make way for them." ”

"I heard from your Aunt Wang that there are many desalination plants built along the coast, how can this water not be enough?"

"Mom, this matter is not as simple as you think, our country's 1.8 billion people, the total annual water consumption is trillions of tons, even if you save now, tens of billions of tons are still needed, right?

Do you know what these tens of billions of tons are?

At present, the world's largest desalination plant produces 700 million tons a year, and almost 100 such plants are needed to barely meet daily needs. ”

Xu Ma and the others were a little frightened.

Xu Dong continued: "One-third of our country's freshwater resources are now transported back from the North and South Poles, but the North and South Poles can't support it for a few years, and the hard times are still to come!" ”

Moreover, there is a big problem with the Arctic and Antarctic itself, and that is the glacial period.

Every autumn and winter, the shipping route will be frozen, and the time for real navigation throughout the year is actually no more than half a year.

"What Dongzi said is reasonable, old woman, don't you nag anymore, isn't it just tens of thousands of yuan a month, and our family can't afford to spend it." Dad Xu helped persuade.

Xu Dong's words gave Xu's father a lot of inspiration, allowing him to have a clearer judgment and understanding of the future situation.

Mother Xu sighed: "Okay, if you don't say it, you won't say it, no one will listen to it anyway." ”

"Grandma, even listen to you, Dabao is the most obedient." Dabao immediately raised his little hand and said.

Mother Xu was overjoyed, hugged her eldest grandson and kissed her fiercely.

……

The next day, perhaps out of "revenge", or perhaps frightened by last night's words, Xu's mother was unusual, and sent Xu Dong to the grain store early in the morning.

They haven't picked up their food for this month!

In October, the family's rations were added together, totaling 172 catties, less than 20 catties per capita.

They have a lot of children, which is a special case, which is understandable.

However, as for Xu's father and Xu's mother, there are only 46 catties of rations, and according to normal standards, they must not be enough.

In addition, rice and corn flour are significantly less in the food ration, but the proportion of potatoes and sweet potatoes has increased by almost 30%.

After buying grain from the grain store, as soon as he walked out of the gate, a large group of people immediately surrounded him.

"Dude, collect grain at a high price, the price is negotiable."

"Do you want to change the grain? Three catties of corn flour for two catties of rice......"

Xu Dong hurriedly waved his hand: "I don't sell grain, and I don't exchange grain." ”

Today is neither the beginning of the month, nor the time to get off work, but I didn't expect that there are still so many second-class dealers at the entrance of the grain store.

Squeezed out of the crowd and finally got back to the car.

"Bang ......"

An aunt didn't know when she would follow, and banged the car window, Xu Dong waved his hand at the other party, indicating that he was not interested and was going to drive.

The aunt was persevering, shouting something in her mouth, Xu Dong had no choice but to press the window, he didn't want to be touched.

"Big Brother ......"

"This aunt, I really don't sell food, and I don't exchange food." Xu Dong said helplessly.

Aunt had a flattering look: "Big brother, Auntie has five catties of corn flour in her hand, and I want to exchange it for potatoes or sweet potatoes with you." ”

"Auntie, I'm really not interested, you better find someone else!" Xu Dong repeated.

"Big brother, help!" The aunt kept pleading.

"I'm sorry!" Xu Dong closed the window and prepared to leave.

Unexpectedly, the aunt knelt directly in front of the car, and began to kowtow without saying a word, it should have been forced, and even her forehead was red.

Xu Dong hurriedly got out of the car to help people, this matter was too disturbing.

"Auntie, you get up first."

"Big brother, please, Auntie's family really can't get by."

"Okay, I can't change it!"

Xu Dong was not moved, he had never seen anything in his previous life, he had seen a lot of this kind of pediatrics, and the reason why he agreed to come down was purely because he was troublesome.

Alas, once you are entangled by this kind of elderly person, it is too difficult to get out, unless you call the police, but the police are also delayed.

When the aunt heard this, she immediately thanked her again and again: "Big brother, thank you, aunt, you are the lifesaver of our family, thank you, thank you!" ”

"Okay, tell me how do you want to change it?" Xu Dong said impatiently.

"Just according to the market price, Auntie will exchange five catties of corn flour for ten catties of potatoes for you, or twelve catties of sweet potatoes, what do you think?"

"No problem, just follow this!"

Xu Dong took out a small electronic scale directly from the car, which he specially bought in order to facilitate the transaction, and kept it in the trunk all the time.

The aunt hurriedly handed over the bag containing the corn flour, Xu Dong weighed it, the weight was exactly the same, and then he opened the bag and checked it, and the quality was okay.

So I couldn't help but nodded.

After putting away the corn flour, he then took out seven or eight sweet potatoes from his bag, put them on the electronic scale, and weighed:

Twelve pounds and eight taels.

"Auntie, see clearly, it's a total of twelve catties and eight taels, and the extra ones are counted as what I gave you."

"Big brother, thank you, you are a bodhisattva!" Aunt thanked again.

Xu Dong waved his hand, immediately bagged the sweet potatoes, and then handed them to the aunt: "Auntie, now we are clear." ”

"It's clear, auntie, thank you."

After Xu Dong left, the aunt instantly seemed to be a different person, and the poor old woman was gone, replaced by a shrewd old lady.

I saw the old lady beckoning to the side, and a middle-aged man immediately rushed out.

"Mom, did you succeed?"

"It's finished." The old lady said proudly.

The middle-aged man was excited: "It's okay now, our family finally doesn't have to go hungry this month." ”

"It's no problem this month, but it's hard to say next month." The old lady sighed.

"Mom, how did you tell that this man was willing to change food?"

"Mom told you that those who came to get food after the beginning of the month, nine times out of ten, there is no shortage of food at home, and they must be very rich, so it's right to pick this kind of person."

The middle-aged man suddenly realized: "No wonder Mom, you only came out to change food now." ”
