The doll is soft and delicate, and her skills are at the top of the 70 exam

Tian Mi glared, "Do I want you to waste your money? During the Chinese New Year, I heard from your parents that you gave chicken legs to Erqiao to eat, and you also used the family's money to treat others to food."

Qi Tianyu, "How can this be compared? Erqiao is my family, so what's wrong with eating some meat? Besides, I earned all the money, so I spent it so much?"

Tian Mi rolled her eyes, "The crystal ball is something that endangers my body, what should I do?"

Qi Tianyu: ...

Jiang Mengmeng weakly raised her hand, "How can this be compared?"

Tian Mi was willful, "Why can't this be compared? Mengmeng, if you stand on my side, how can you help them?"

Jiang Mengmeng blinked, "I will help you or not."

Qi Jiu tugged at Jiang Mengmeng.

Jiang Mengmeng, who was about to open her mouth, shut up.

Qi Tianyu also said that he could not win against Tian Mi, so he snorted coldly and stopped talking.

Dabao was helpless, "The structure inside Mengmeng is similar to the internal structure of your previous washing machine. She doesn't want it and you just want it."

Jiang Mengmeng's eyes lit up, and she grabbed Tian Mi, "Are you sure you don't want it?"

Tian Mi was still angry in her heart, and she was also taken aback at the moment, mainly because she was pulled anxiously.

"No," Tian Mi said blankly.

Jiang Mengmeng happily said to her friends, "Then let's dismantle it?"

Tian Mi jumped far away, "It's poisonous! I don't want it."

Jiang Mengmeng waved her hand indifferently, "This glass ball is separate from the base, I want to dismantle the base."

Qi Tianyu was interested in this, "Is it really unbreakable?"

Jiang Mengmeng didn't know either, so she asked Dabao.

Dabao nodded, "No."

With the right words, Jiang Mengmeng became more interested in dismantling this.

Qi Jiu didn't want to dismantle it, the music rotation below is very simple, he already knew the principle, "I know, there is no need to dismantle it."

Jiang Mengmeng turned her head, "Do you understand the principle of repeated rotation on both sides?"

Qi Jiu: ... "No."

Jiang Mengmeng curled her lips.

Qi Jiu scratched his head, "The principle is very simple, it should be similar."

Jiang Mengmeng didn't talk nonsense, took out a piece of paper from the bookshelf, and drew a rough mechanical structure in front of several people.

Tian Mi lay on the table and asked curiously, "What is this? This ball?"

Qi Jiu frowned, "This is different from the music box rotation, it's more complicated."

Jiang Mengmeng shook her head, "Did you see this belt? The motor drives the pulsator to rotate through the deceleration of the belt. It has a similar principle to this music box. Here, the pulsator is controlled to stir the water in forward and reverse directions, and it is stirred and rubbed back and forth in the forward and reverse directions to remove the water. The purpose of the stain. Is it turning left and right like this ball? It is repeatedly rotating and dialing back, does it look like?"

"It's not like!" Qi Jiu directly objected, "the music box has a protruding part behind the disc. This part makes the claw wheel rotate, and the claw wheel moves the comb teeth to play music. It contains (governor) and (worm screw) ), when the governor rotates at high speed, it will generate air resistance, and then rotate, it has nothing to do with this, so don’t bother.” Anyway, I understand.

Jiang Mengmeng was very angry, "You are so stubborn, I always said this is different, how do you know it is different without taking it apart? When the governor rotates at high speed, there is air resistance, we speed up the energy output of the clockwork, and release more energy. Big energy, increased speed and friction, and besides, I didn't draw the rotating base."

Qi Jiu pursed her lips, "It's the same if it's not a music box. The rotation can't produce such a large amount of energy, and the material is not good."

Jiang Mengmeng jumped, "Then find a way to make it work."

Tian Mi and Qi Tianyu swayed their heads from side to side, looking at Jiang Mengmeng for a while, and Qi Jiu for a while.

They quarreled.

Tian Mi slapped Qi Tianyu on the head, "Don't turn around, I'm dizzy."

Qi Tianyu bared his teeth in pain, "You're dizzy because you turned around by yourself, hit yourself, why did you hit me?"

Tian Mi felt a little guilty, "I'm afraid of pain."

Qi Tianyu became even more angry, "Are you afraid of pain and I'm not afraid of pain? I'm not made of iron."

Tian Mi got angry when she was yelled at, "What's wrong with you boys who have rough skin and thick flesh? Is it possible that you still want to beat me back?"

Qi Tianyu: Σ °△°|||)︴!!!

"You are unreasonable! I will call back!"

Tian Mi put her hips on her hips, "What's wrong with my reasoning? If you hit me, I'll complain to Grandpa Qi!"

Qi Tianyu was dumbfounded: "I, I, I... I don't care! I will call back! You go to file a complaint and I will call back too!."

Seeing that Tian Mi and Qi Tianyu were about to stretch out their hands to do it, Jiang Mengmeng and Qi Jiu hurriedly braked, ignoring the dispute, and pulled one at a time.

Jiang Mengmeng, "Oh, don't do it, don't do it, don't hit it."

Qi Jiu, "Qi Tianyu, you will be punished for hitting someone."

Jiang Aiguo & Bai Mei sleeping in the room: .....

Jiang Aiguo: I have a bad temper!

"It's so noisy! Why don't you let people sleep well?"

Baimei: What a bad girl!Throw it away!

"Go down and have a look," he said, kicking Jiang Aiguo.

Jiang Aiguo was really annoyed by being kicked twice in the morning.

Furious, Jiang Aiguo jumped out of bed, opened the curtain and threw the four out.

"What are you arguing about, what are you arguing about, go out and quarrel with me!" Jiang Aiguo waved his fist viciously, "If you continue to quarrel with me, I will beat you!"

Qi Tianyu holding a music box;...... so fierce~

Tian Mi swallowed, "Mengmeng, what should we do?"

Qi Tianyu was still angry, "Take your things yourself, and I'll give this back to you!"

Tian Mi hugged her in shock, "Qi Tianyu, you are narrow-minded, can you take it?"

Qi Tianyu turned his head, "huh~" A petty mind is a petty mind, anyway, I won't help with it.

The people came out but the dogs didn't.

So when the four of them were worried, a fluffy head quietly emerged from the crack of the door.

Qi Tianyu's eyes lit up, and he patted Jiang Mengmeng, "Mengmeng, your door is open!"

Jiang Mengmeng hurriedly looked at it, "It's not that big!"

Big deal: "Wow~"

Qi Tianyu quickly covered its mouth, "My little ancestor, please keep your voice down and don't wake up Mengmeng's father."

Sticking out his tongue a little bit.

Wangcai behind him barked in displeasure.

Jiang Mengmeng patted her big brother, "Come out quickly, don't block the door."

I would like to come out even if I am older, but I have gained weight and my butt is stuck in the door.

Jiang Mengmeng: ...

The little girl and the silly dog ​​stared wide-eyed.

At least I thought Jiang Mengmeng was playing with her, so I was happy, "Woof~"

Qi Tianyu laughed, "This silly dog!"

Jiang Mengmeng punched him, "Why are you laughing, why don't you hurry up and hit the handle, pull it out, Zhuangzhuang and Wangcai are still inside."

Qi Jiu was a little nervous, "Mengmeng, uncle and aunt don't eat dog meat, right?"

Jiang Mengmeng scratched her head, "I don't know, the brigade where my family lived didn't have dogs before, so I didn't have a chance to eat dog meat."
