God of danger

For a circle with a diameter of 10, remove 3/4, and then dig out a triangle from the 45° tangent, and find the shadow area of ​​the remaining part. Why the fuck is it 100?

If you don't dig out the blanks and fill the shadows, the area is less than 80%.

The answer seemed to be based on emotions. The math teacher wanted to live a few more years, so he asked Lu Rongxing to roll back to his seat with a dark face.

Zhang Yiye crossed the legs of the bench to let the tablemate go back to the nest, and as soon as he sat down, he couldn't wait to push a piece of paper over, and asked the doubts in his heart.

While sitting, Lu Rongxing pressed his finger on the paper and pulled it over, and saw a row of calligraphy on it that was uglier than Guan Jie's Wang Ba characters.

Zhang Yiye: Where are the things in the pencil case?I just looked at your table, no, are you hiding?

Taking the opportunity to put things for Lu Rongxing, he fumbled around in the cavity of the table next door, not even letting go of the back of the upper panel.

Many students put double-sided tape on that position, especially those boys who like to comb their hair into a middle part during class, and girls whose spring hearts have sprouted and remember the number plates of love. They also have a private plot where they can hide the small comb mirror and colorful letter paper.

But on the back of Lu Rongxing's desk, Zhang Yiye only felt the barb of a stubble.

Since the things were not in the table, they could only be taken away by him... Zhang Yiye thought about it carefully, but he didn't know when he did it.

Lu Rongxing played tricks when picking up his schoolbag.

Because of long-term pipa practice, the dexterity of his hands is unmatched by ordinary people, and his sense of strength is also accurate. It takes two to three seconds to open the pencil case, grab the turtle with the left hand, and flick the pencil in with the right hand.

After that, he used the cover of his schoolbag and his position against the wall to stuff the turtle on his body as fast as lightning.

Faced with Zhang Yiye's enthusiastic exploration, Lu Rongxing gave him a sideways look with a "you're boring" look, his right hand didn't move, and his left hand quietly left the table.

At this moment, Zhang Yiye was all interested in him. When he noticed that he moved a little, he immediately bobbed his head and tried to see everything clearly.

Then he saw Lu Rongxing pull up the left hem of his clothes and remove a turtle shell from the elastic band of his trousers.

Zhang Yiye was stunned for two seconds in disbelief, and then burst into a burst of laughter from the bottom of his heart, but he still retained a trace of reason that he was in class, and only let out a suppressed sneer that sounded like he was farting.

"No, I'm stupid!" Zhang Yiye's flying paper transfer strategy was scrapped after passing one sentence, and he couldn't help talking about more efficient communication, and whispered in amazement, "It takes such a hard work Isn’t it just a turtle?”

"Yes, it's a tortoise," Lu Rongxing said casually, but didn't say anything.

But the problem is that it is Guan Jie's tortoise.

He couldn't explain to Zhang Yiye that the particularity of the subject was a sense of responsibility that could only be understood but could not be expressed in words.

For example, the tortoise was confiscated in this class, and Guan Jie came back and rushed to nothing. He absolutely did not dare to say indignantly that it was all due to Lu Rongxing, and let him pay for it, because the teacher took the tortoise.

He would hold the empty pencil case in disappointment and say "Oh", and then languid before the next thing that attracted his attention. During this time, Lu Rongxing always felt that he owed him a lot of money. A debt that is still unpaid.

Seeing that he had admitted it, Zhang Yiye laughed even harder, his shoulders shaking like chaff: "I didn't say that, you are so fucking talented, and you can't even find it in your pocket if you don't wear it on your belt. Hahahaha I'm dying laughing."

Lu Rongxing was made worse by his laughter, he held the tortoise that shrank again after the accident, and felt that Guan Jie's luck was contagious.

Because it disturbs the people, the pencil case can no longer be put away. Lu Rongxing thought about it, and took a picture of Yiye under the desk: "Use the wristband for me."

Zhang Yiye didn't laugh enough, and went to dig out the table while diverging his thoughts: "You strangle the tortoise on your pants, Lao Li asked you to go up to do the questions, if it falls down while you are walking, or it suddenly scratches you You can't hold back the itch, so what's the matter?"

"That's you." Lu Rongxing was a person who planned ahead, he deliberately used his arms to hold the turtle down when he walked.

As for the second worry, it is even more unfounded. He is not ticklish at all, and he is a person without weaknesses.

Zhang Yiye took out a black wristband and continued to laugh: "Then how could it be me, brother? As soon as the teacher said it, he immediately took out a tortoise and said that I made a mistake and dare not dare next time, that is me."

He is not that kind of traitor, Lu Rongxing didn't say anything, took the wristband and put the turtle on it, pulled off the transparent glue, wrapped it around the middle part of the turtle's carapace, and put the two things together on the table .

There is a layer of rough and fine wool on the outside of the wristband. The tortoise's claws hook the line, so it doesn't crawl very much. In addition, the fabric is thick and soft enough. Although there are still some subtle sounds, the front and rear seats can no longer be heard. Passed half a class safely.

Teacher Jin's class is always fascinating and full of laughter.

Guan Jie and Xie Jun shared a laboratory table, took out the internal organs of the fish according to the teacher's steps, and marveled at the still beating heart after being separated from the body.

Jin Teng used this to introduce the concept of cells that he only learned in junior high school, and told them that geckos' tails can jump, and fish in the pot can jump, which is the reason why some cells are still active.

Guan Jie didn't have a knowledge system, and he was in a fog when he heard it. He raised his finger and put the sticky little heart on his fingertips. Watching it beat lonely and tenaciously in the light, he felt a strange feeling in his heart. Feel.

Jin Teng talked about fish gills to fins, telling everyone the necessity of the existence of each organ.

The short 45 minutes was not enough. When the bell rang, he said, "Let's talk about the lungs...", but after the ringing, he squinted out the window, put down the chalk and said, "I'm on vacation, so I won't tell you."

Guan Jie mixed up in the large army and made a fuss, shouting that Teacher "Jin" was the cutest person in the school.

The lovely Jin Teng looked at their duplicity, smiled and turned to wipe the blackboard, thinking that one day you will understand that those teachers who are willing to drag the class for you are actually more responsible people.

Because he wanted to see how long the little heart could beat, Guan Jie didn't wash his hands, and continued to run back to the classroom with the fish heart on his back to carry his schoolbag, and then went down to find Lu Rongxing.

Before Class [-] of Grade [-] finished class, Guan Jie sat on the flower bed opposite the classroom for a while, staring at the tortoise who missed him.

Wu Yimin came down from the second floor and saw him sitting on the ground. He wanted to call him to go home together, but he stopped after taking a step.

He has never been short of playmates, and the loss of one Guan Jie will not affect him. If Guan Jie doesn't take the initiative to find him, then he can go and play with others.

After making up his mind, Wu Yimin turned around on the spot, pulling the shoulder strap of his schoolbag away from the teaching building.

Five or six minutes later, Guan Jie finally heard the special noise coming from the classroom opposite. He looked up to the door, and after the swarming troops squeezed out, he easily saw Lu Rongxing.

He jumped up and ran to pick up the tortoise, but before he met, he saw Zhang Yiye who came out with Lu Rongxing's shoulders on his shoulders and started laughing wildly at him.

It's polite to smile when you meet, but it's weird to be so ridiculous.

Guan Jie blankly shifted his eyes from Zhang Yiye to the side by one unit, and after meeting Lu Rongxing's eyes, he turned his eyeballs to the side again.

That probably means, is the guy next to you crazy?

Lu Rongxing was holding a pencil case, and before he left the classroom, he was still thinking that he must learn his lesson next time and not take things from Guan Jie casually, but when he saw someone, all his thoughts were refreshed.

Seeing Guan Jie pinching a finger, he unconsciously focused his attention on the opponent's finger.

When I stared at it, I felt that there was a mass of blood, but when I walked a little further, I found out that it was not. My heart was full of activity, and after I asked the teacher, I found out that it was the internal organs of a fish.

Before Lu Rongxing could ask him why the fish didn't let go of its heart even though it was dead, Zhang Yiye couldn't bear it anymore and interrupted forcefully: "Brother hahahaha, where did you get the turtle, it almost killed you Brother Lu was killed."

Guan Jie's heart skipped a beat, he stared at Lu Rongxing's face from the corner of his eye and said, "Huh? I fished in the river when I was in biology class."

Zhang Yiye immediately praised him as a talent, he could even catch bastards, and then laughed vividly at the jokes in class.

When Lu Rongxing put the tortoise on the elastic belt, he felt that it was the best choice after weighing the pros and cons. Even if Zhang Yiye died laughing, it would be wise, so he didn't feel embarrassed.

Zhang Yiye's jaw dropped in surprise when he laughed at him, so he laughed at Zhang Yiye with a low smile.

Zhang Yiye refused to admit it, and insisted on pulling Guan Jie to stand in line.

Guan Jie glanced guiltily at Lu Rongxing's trousers that were covered by his jacket, wanted to laugh but didn't dare, and finally couldn't hold back his internal injuries and laughed more and more happily: "It's not funny at all——"

Lu Rongxing poked him in the stomach with the pencil case that had been repacked with a turtle, and asked, "Do you have a conscience? Or are you human?"

Guan Jie took a deep breath timidly, his belly sank softly, and then burst back in an instant. He really felt sorry for Lu Rongxing, but he really couldn't restrain his surging laughter.

Holding his index finger up, he laughed until he died and said, "Yes, yes, yes...I, I have two consciences now, I'm sorry, don't be angry..."

Lu Rongxing wasn't angry either. He hadn't been very angry since he was a child. At first, he was afraid that Wang Yang would reason with him. Later, he really didn't care about many things.

He picked up the pencil case himself, and Guan Jie couldn't be blamed for the episode in class, he just felt it was nonsensical.

He is a well-behaved person who is still trying to listen even if he doesn't understand the class, why does he have to go through this?

Due to the different direction of home, Zhang Yiye could only be happy to the bridge. He and Lu Rongxing made an appointment to watch ghost movies together at night, and went home to report to his grandfather.

Guan Jie and Lu Rongxing turned to the right, immediately opened the pencil case, and took out the tortoise.

The tortoise that hadn't touched water in one lesson obviously lost the moist feeling it had just caught. Guan Jie held the shell in his hand and said, "It won't die of thirst, right? Why hasn't it moved for so long?"

Lu Rongxing immediately felt that this tortoise was a bit rebellious, rebellious when it was time to be quiet, and could play dead while having fun.

"No way." In the animal world, it is said that turtles can live to be hundreds of years old. Lu Rongxing thinks that it should not be so fragile. "There is a faucet in front of the motorcycle repair shop in front of you. Go and get some water."

Guan Jie took the pencil case and trotted to fetch the water.

Lu Rongxing knew that he would wait for him, so he followed in no hurry, just in time to bump into someone calling him.

"Xiaojie, come on, help me take this 100 yuan to the small supermarket and break it into small change."

Guan Jie took a box of tap water with a splash, and soaked the turtle in it full of anticipation. After waiting for a while, a string of bubbles with no room to rise appeared one after another.

If you can spit bubbles, you are still alive. Just as Guan Jie was about to tell Lu Rongxing, someone called his name. He turned around to look for it, and soon saw Wu Yimin's face on the card table in the house next to the repair shop. dad.

Where everyone grows up, they seem to be able to pick a general from among the dwarfs, and find a lazy rascal who makes people feel sad and angry about their misfortune. Wu Yimin's father is this kind of person.

He can not take a shower for a week in summer, let the weeds in the field cover the seedlings, dare to take the child's tuition fee on the card table, and turn around to steal his mother's pension...

This person can disappoint and deceive anyone, but he never treats himself badly. Playing cards is his favorite thing, so he is at the poker table every day, or on the way to the poker table with someone.

The aunts in the yard are always talking about him, saying that he is not a thing, and pitying his wife and children at the same time.

Guan Jie couldn't listen to those trivial and lengthy chatter, he didn't have that patience, he didn't like this person purely because the smell on his body was too smoky, the smell of sweat and smoke was mixed together, getting close to him It makes people want to cover their nose or hold their breath.

And because he didn't know, Guan Jie complained for Wu Yimin, he felt that his classmate was very pitiful, he didn't have anything to eat.

But it doesn't seem to be because of poverty, because Guan Jie met Wu Yimin's father several times on the street, and saw him eating snacks that he would only eat when he was holding a child.

Guan Jie felt that my mother, in his house, sometimes Li Aili would hesitate for a long time if he wanted to eat a 5 cents pancake, but all the food the family would buy was for him and his sister, which were much more expensive than pancakes.

So Wu Yimin's father is a father or a son, he sometimes gets confused.

Guan Jie didn't like to talk to him at first, but he just got into an awkward fight with Wu Yimin yesterday, so he clumsily and too simply blamed his father for his classmate's lack of loyalty.

It took him many years to understand that everyone alive in this world has his own philosophy of survival. The disadvantaged are not only poor, but also very cunning, while the elite seem to be invincible, but sometimes they can be broken with one blow.

But at this time, Guan Jie just said: "I gave you some change, do you want to give me some money?"

In the town, letting children run errands usually makes a fuss, and gave it fifty cents, but Wu Yimin's father was so generous, he smiled and scolded: "You're pretty good at business, so I'll give you one yuan to buy something to eat, hurry up .”

Guan Jie was just playing around, but he didn't expect that the other party would actually give it to him. Hearing this, he was stunned, and turned to look at Lu Rongxing, whom he would count on when he had nothing to do: "Shall I change it for him?"

If Li Aili knew that he was asking others for money outside, he would definitely take care of him when he returned home, but for one dollar, he could buy a pack of Haojindao and three bubble gums, which was a real temptation for him, and Guan Jie might not really dare to take it , but it was his instinct to struggle.

"No," Lu Rongxing pushed him without thinking, signaling Guan Jie not to pester him.

Guan Jie saw that the old man was so determined, so he left without resisting, without asking why.

And Lu Rongxing's logic is very simple, he is not short of this dollar, and Guan Jie is asking for his opinion.

Ten minutes later, the two returned to the compound, and saw a watermelon seller and tractor parked across the road.

In the morning, Li Aili gave ten yuan to Guan Jie to buy a few watermelons when he met at night, and to eat some fresh ones when his sister came back.

Guan Jie handed the pencil case to Lu Rongxing, climbed into the car, pretended to be good at it, and knocked left and right, but in fact he couldn't tell the difference.

The boss knew that he was pretending at a glance, and asked him with a smile: "Little boy, how many melons do you want to buy?"

Guan Jie didn't have a clue at all, he looked at the money and said, "Buy the ones that don't cost more than 10 yuan."

The boss responded: "You pick it, and let me weigh it for you when you pick it."

Guan Jie knows how to pick a fart, and after pretending, he moved out the rhetoric taught by Li Aili in the morning: "You help me choose, I want sweet ones, not greasy ones."

The boss readily agreed, and seeing that he was small and deceitful, he brought a watermelon that was so big that no one would buy it and asked him, "What do you think of this? It's guaranteed to be crispy and sweet. It's not good." You don’t need money to eat.”

Just as Lu Rongxing felt that this scene seemed familiar, Guan Jie's indifferent voice sounded.

"Then our family doesn't have to eat anymore. We only eat watermelon for three meals a day, and we have to eat it for two or three days to get rid of it. Do you think I'm a fool?"

Lu Rongxing almost died laughing when he heard it under the car.

One year around this season, two melon dealers came to the town, using the above sales words and adding a compliment of "I won't sell to others, I only sell to you because you are cute", fooling you. Jie bought three watermelon kings that made people shy away.

Then for three days in a row, Li Aili invited the whole compound to eat watermelon.

Now Guan Jie has grown up, so he didn't buy a melon rind this time, and when he entered the yard, he still said that these adults are too bad.

Lu Rongxing laughed at him in his heart, saying that other people do business with many people, but they only fooled you, so you should reflect on it anyway, but you will agree with them all.

Guan Jie was stroked by his hair, and when he walked under the basketball hoop, he calmed down. He held the pencil case and simulated a turn and jump with the ball. He didn't know how far the top of his head was from the basketball hoop, but the turtle flew out of the pencil box.

Guan Jie chased to pick it up, but before he could touch the shell, he caught a glimpse of an unfamiliar motorcycle parked in front of his house, and then he heard Guan Min's begging.

"...You guys go away, I beg you! I'm telling the truth, what else do you want me to say..."
