"Call it a day!"

A book thrown out by Lu Xi drew a graceful arc in the air, passed through the window, flew into the balcony, hit the protective net, and finally landed on the fence.

The book was blown open by the wind, and you can see the title of the book on it - "Special Question Bank of Ideology and Morality in the Political Examination of the Middle School".

Today is Sunday, June 14th, the day before the high school entrance exam.

In fact, it was already a holiday the day before yesterday, but Lu Xi still has a little bit of ideological and moral information that he hasn't finished reading.

But now, she was tortured enough by the course of ideology and morality, and finally conquered it all.

It's not easy, Lu Xi resisted the urge to push everything on the desk to the ground, and stood up suddenly.

"On this turbulent battlefield, the Storm Boy appears...... Comeon, counter-war, counter-war, the ace must be wild, break through the universe to level the world...... Oh, counter-war, counter-war wild, ace to vent, battle is our stubborn pen fun pavilion www.biquge.info...... I'm going to manipulate my power, show my might, and watch this dragon battle ...... wild."

Humming a song, Lu Xi walked out of the door.

In the restaurant, only Lu Zichuan was eating alone.

The sister-in-law was looking after the store, and the eldest brother brought her food.

Business is generally good on weekends, and at least one person needs to be in the store to greet customers.

Compared with Lu Pingsheng's Mu Ne, Lin Dongmei, who is eloquent and can talk to a stranger for half a day, is undoubtedly more suitable for doing business in the store.

"You're singing?" Lu Zichuan paused in his tornacle, tilted his head and asked Lu Xi in surprise.

"Any questions?" Lu Xi was in a good mood.

"Counter War?"

"I don't know, I can sing whatever comes to mind."

What "Counter War", does it matter, hum casually, she just needs to be able to be wild and vent, because she is immersed in the course of ideology and morality, and the sullen breath accumulated in her heart.

Lu Zichuan on the side didn't speak again, he felt that this little "elder" had experienced a hospitalization, and the whole person had changed a lot.

Of course, his temperament is still so stubborn, and he hasn't changed his dead study.

But the subjects he was good at suddenly deteriorated, but the math and science scores that he was not good at suddenly rose to the highest point that surprised him, a genius who thought he was extremely talented in math and science.

And now, he actually took the initiative to hum the saliva song that he used to disdain.

What's even more strange is that her biggest wish before was to be admitted to the provincial key Yunjiang Middle School in Yunjiang City, but when she filled in the volunteer, she actually filled in Huafu, and even her grandmother and third uncle were shocked.

I really don't know where she got the confidence to report this best high school in the province?

"You use it slowly, I'm out."

When Lu Zichuan stopped throwing cups and thinking about problems, Lu Xi put down his chopsticks after eating.

"Where are you going?" Lu Zichuan asked subconsciously.

Lu Xi waved his hand, leaving a sentence of "Do you need to report to you to get the approval of the pass", then picked up the cardboard box containing the hanging steam iron and walked away.

Just now, Lu Pingsheng called back, and she received that Lu Pingsheng asked Lu Zichuan to send this hanging steam iron to the store.

However, Lu Xi was at school and at home, ignoring what was going on outside the window, and he had been at home for nearly a month, and he was about to go out for a walk, so he took over the task of delivering the iron.

And Lu Zichuan's side was swallowed by Lu Xi's words.

"Sure enough, the nature of the country is easy to change, and no matter how it changes, it can't change the sharp teeth."

Out of the Heyun Flower Garden Community, Lu Xi, who was holding a cardboard box, walked to the nearby Changlong Market, where the eldest brother and sister-in-law's clothing store opened.

After walking for about ten minutes, she came to the vicinity of Changlong Market.

Changlong Market is an old market for many years, and it looks very old, but the cleanliness and sanitation are good, but it does not give people a dirty and messy feeling.

Rumble!

Outside the Changlong Market, several large machines are drilling violently into the ground, and the strong tremor can be felt even from a distance.

To the east and west of the market, there are two large properties under construction at the same time.

Mei Yi fashion clothing store, this is the name of Lu Xi's eldest brother and sister-in-law's clothing store, Lu Xi came to the door with a cardboard box.

"Didn't you ask Zichuan to send it?" Lu Pingsheng saw that it was Lu Xi who sent the iron, and couldn't help frowning, "What a spoiled, heartless lazy thing, see if I can't clean him up when I go back." ”

He also thought that the reason why Lu Xi would send the iron over was because Lu Zichuan asked for it. Because in the past, Lu Zichuan often commanded Lu Xi to do this and that. And Lu Xi always swallowed his anger and didn't come as required because of the send-off fence.

However, this is all trivial things in the past, although Lu Pingsheng also thinks that Lu Zichuan is not doing it right, but young people, it doesn't matter if you do more and do less. It's just that he didn't expect his son to know that his "elders" would take the high school entrance examination tomorrow at such a time, and he was so ignorant that he shirked what he wanted to do to Lu Xi.

This annoyed him.

Lu Xi saw that Lu Pingsheng had misunderstood, and explained, saying that he wanted to come down and take a walk, so he would take the initiative to send the iron over.

After explaining, seeing that Lu Pingsheng was still a little angry, she changed the topic: "By the way, what's going on over there?" ”

Lu Xi asked about what he had just seen about several large machinery drilling into the ground.

"The market will be demolished and rebuilt, and the preliminary geological testing will be carried out." Lu Pingsheng replied.

"It's going to be demolished?" Lu Xi was stunned, "What about these clothes?" ”

The store is full of all kinds of clothes, and the value is not more than 100,000.

"It will be demolished after a while, and your sister-in-law has already found a store elsewhere, and will move there when it is going to be demolished." Lu Pingsheng said, his face was slightly sad.

Obviously, the market was demolished and rebuilt, and although a new store was found, it still had a great impact on business.

"Where's my sister-in-law?" Lu Xi walked around the store and didn't see her sister-in-law.

"The newly rented store is going to be renovated, and she went to the supermarket to look at the decoration materials."

Rumble!

With the rumbling sound, Lu Xi felt his feet shake slightly, as if there were several overloaded heavy trucks passing by.

But this is the market, where are the heavy trucks.

As the two spoke, several customers came in in pairs to look at the clothes.

"If you want to take a walk, walk around, but don't walk too long, so as not to get tired, go back early to rest, and tomorrow will be the exam." Lu Pingsheng needed to greet customers, so he told Lu Xi.

"I'll sell it for you." Lu Xi thought that it would be in vain to go outside, it was better to stay and see if she could help, she hadn't done this laundry sale yet, so she was a little curious.

"Where can I use you, it's better to go to Changlong Supermarket to see if your sister-in-law has found good materials." Lu Pingsheng was unwilling to delay Lu Xi's rest time, so he thought of a roundabout way.

"Okay." Lu Xi nodded.

Mei Yi clothing store is not far from Changlong Supermarket, and Lu Xi walked for about five minutes to reach the supermarket door.

Bang!

It's just that when she was about to walk into the supermarket, a strong tremor suddenly came, and then a loud bang sounded, and the door of Changlong Supermarket suddenly collapsed, along with the collapsed building.

This sudden change startled people passing by outside the supermarket.

"Ah......h

Someone screamed.

"The supermarket collapsed ......"

Someone shouted in horror.

Lu Xi was not frightened or screamed, she was observing the collapse inside through the half-collapsed supermarket door.

Large swaths of ceilings were smashed down, large and small shelves were smashed, and all kinds of commodities were stacked and rolled to the ground, making a mess.

In the supermarket, some of the customers who were shopping were directly smashed to the ground by the falling ceiling, some were hit by the shelves and their heads were bleeding, some were lucky not to be injured, or they all fled in panic......

Rumble!

The tremors on the ground have not stopped.

Seeing that the customers who were still able to move escaped, Lu Xi walked over.

The sister-in-law did not come out, and with the shrewdness of the sister-in-law, she did not escape immediately, indicating that it was likely that she was injured and could not come out by herself, and she wanted to go in and have a look.

"Girl, don't go in, there may be a second landslide, wait for the ambulance crews to come." The passers-by next to him saw that Lu Xi was going to go in, and hurriedly persuaded him.

At this moment, for fear that there would be a second landslide, even well-meaning passers-by did not dare to go in, and only went outside to help those who escaped and were injured.

Without hesitation, Lu Xi jumped over a broken advertising box that fell to the ground and got into the supermarket.

When she entered the supermarket, she found that the collapse was even worse than what she saw outside.

In a messy and messy environment, there are shouts, cries, moans, and moans everywhere, and it is very miserable and desolate.

Decoration materials, hardware area, Lu Xi found a pointing sign at the entrance, and walked towards the hardware area with broken glass all over the ground.

On the ceiling, which had not collapsed, the remaining fluorescent lamps flickered and flickered, alternating between light and dark, pulling and pulling the exposed wires that were dragging in mid-air, sparking and snorting from time to time.

Seeing that it was possible that the top would continue to collapse, Lu Xi didn't find the figure of his sister-in-law, and he couldn't help but start to get anxious.

"Sister-in-law, sister-in-law, where are you, Lin Dongmei ......"

"I'm here."

Lu Xi followed the sound, and sure enough, he saw his sister-in-law Lin Dongmei, who was trapped on the ground by several shelves, and all kinds of sundries were stacked on the shelves.

"How are you now?"

Because she was pressed at the bottom, Lin Dongmei could only reluctantly stretch out a hand and wave at Lu Xi, signaling her to be there: "I'm not injured, but I can't get out of being crushed underneath, you go and call your brother to help me." ”

Bang!

Suddenly, the ground shook again, and a corner at the end of the hardware area collapsed, although it did not affect Lin Dongmei's side, but depending on the situation, it was only a matter of time before this side collapsed.

Lu Xi walked to the pile of things that were pressed on top of Lin Dongmei and tried to pull it, but it was too heavy and didn't move.

With her strength alone, it is completely impossible to push those heavy objects away and let the sister-in-law out.

What's more, those sundries are pressed horizontally and vertically on it, and it is likely that one is careless, and the whole body will be moved, and the heavy objects will not be moved, but all the things will be completely pressed down, and then the person may really be gone.

"I'm going to go......"

There is a great terror between life and death, if Lin Dongmei could barely maintain her composure just now, she is now completely panicked, and even her voice is crying with trembling.

Lu Xi calculated in his heart and went out to call his eldest brother to help, but it was too late in time.

Her eyes kept scanning back and forth over the pile of debris, and the two fallen shelves formed a triangular space with the ground, and between the triangular spaces, several steel pipes and several iron tongs were inserted diagonally, forming a more complex geometric space.

The triangle is the most stable geometric figure, and it is precisely because of this that Lin Dongmei, who was pressed underneath, was protected from being really hit. But there are too many debris on the shelves, and the support formed by the two shelves rattles under the weight and is about to break at any time.

"What should I do, what can I do to move the heavy objects away and let my sister-in-law come out?"

Lu Xi's brain power was burning, and the problems of mechanics and geometry in his mind were intertwined.

At present, she has only learned the simplest mechanics, the concept of the pole and the most basic plane geometry, and the debris pressed on Lin Dongmei involves a deeper layer of mathematical knowledge.

"Give me a fulcrum, and I can lift the earth."

What she was looking for was a fulcrum that could pry up heavy objects and prevent them from coming down directly.

First of all, it is a matter of calculating the force, the point, magnitude, and direction of the force, there is no precise number, and Lu Xi can only approximate it.

Then there is the problem of geometry, the real space is three-dimensional, but the three-dimensional geometry is the extension and expansion of the plane geometry, the basic way to solve the three-dimensional geometry problem is to analogize it or transform it into the plane geometry problem, and the transformation process is to continuously ascend and decrease the dimension between the two.

Unknown problems are known, multi-dimensional problems are reduced, and complex problems are simplified.

The three-dimensional images that are so complex that they seem to be twisted into a ball of twine are established in order in Lu Xi's mind, and after they are established, they are separated one by one like a cocoon, and quickly analyzed, simplified into points, lines, and surfaces to form a plane figure.

……

Using the knowledge of simple plane geometry to solve complex three-dimensional geometry problems, Rao is Lu Xi awakened his talent for mathematics and physics, and he is also sweating profusely in calculations.

What's more, the entire supermarket is in danger of collapsing, and this huge external pressure makes her subconsciously clench her fists.

"Embarrassed ......"

When Lin Dongmei saw Lu Ximu there, she seemed to be scared stupid, and she was finally so scared that she couldn't help crying.

For the cry of the sister-in-law, Lu Xi didn't seem to hear it at all.

When the calculation of the race against time came to an eyebrow, she heard the voice of her eldest brother.

"Dongmei, ......"

"Dongmei, Xixi, where are you?"

"Big brother, we're here, come here."

Lu Pingsheng, whose face was pale and frightened, stumbled and rushed over, probably after a fall, and a big hole was broken in the knee of his right leg, with blurred flesh and blood on it, and the whole person was very wolf.

"Dongmei, if you're scared, I'll save you right away."

Lu Pingsheng tried to make himself look calm, he walked in front of the heavy object, trying to lift it up with both hands.

"Big brother, don't move there." Seeing this, Lu Xi hurriedly shouted.

Seeing Lu Pingsheng looking at him with anxious and puzzled eyes, Lu Xi hurriedly explained: "As soon as you move there, the whole top will collapse." ”

Click, as if to hint at the correctness of Lu Xi's words, the pile of heavy objects sank a little more.

"I can't pull this steel pipe." Lu Xi pointed to the steel pipe that was protruding between a pile of heavy objects, and said, "Just pull it out." ”

Hearing Lu Xi's words, Lu Pingsheng subconsciously looked at Lu Xi's eyes, full of emotion, but he didn't panic.

"It's too late to hesitate." Lu Xi urged, she knew that her request sounded too ridiculous, but there was no better way than to do so.

Lu Pingsheng glanced at his wife again, walked up to the steel pipe, grabbed it with both hands, and pulled it hard.

With a click, the steel pipe was pulled out at once.

Then there was a crackling, chopping waves, and the pile of heavy objects separated from it and fell to both sides, and Lin Dongmei, who was pressed in the middle, was suddenly freed.

Rumble!

The whole supermarket was shaking, and from time to time there was debris falling down from it.

"Run!"

Lu Pingsheng pulled up Lin Dongmei, who was scared and weak, and took Lu Xi and ran outside the supermarket.

As soon as the three of them ran out, they heard a loud noise again, and when they looked back, it was the hardware area, and the whole thing had completely collapsed, and a large cloud of dust rolled into the sky.

If they hadn't been one step faster, they might have died by now.

At this moment, Lu Xi was blown by the cool breeze outside, the dense sweat on her forehead was blown off, and the whole person who was loosened felt light, and she was also scared just now.

"Wow!" Standing far away from the collapse of Changlong Supermarket, Lin Dongmei had palpitations, and then hugged Lu Xi in fear, choking with tears in her eyes: "If it weren't for you, I would ......"

"It's okay, it's all over."

Being hugged by her sister-in-law, the first time she had such intimate contact with her sister-in-law, Lu Xi felt a little embarrassed, but she knew her sister-in-law's mood very well, so she had to gently pat her sister-in-law's shoulder with her hand and comfort her softly.

It was only when her hand slapped down, and she suddenly raised it in pain.

"Xixi, what's wrong, are you hurt, where is it?" Sister-in-law Lin Dongmei heard Lu Xi's cry of pain and immediately checked it reflexively.

"It's okay, it's just that my right hand hurts a little."

Lu Xi looked at the right hand, the fist broke the skin, the blood oozed out, the whole was red, and the hot pain came from the heart. Then she remembered that she was sinking into the calculations when something had fallen, and with a punch from her right hand, it knocked the thing away.

"It seems that I really am not the iron-blooded man who can run horses on his arms before."

Next, Lu Xi was dragged to the hospital by Lin Dongmei.

In fact, such a small injury, in Lu Xi's opinion, he doesn't even need a band-aid, and he will naturally get better in a few days. But in Lin Dongmei's heart, at this moment, she is more important than anything.
