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

Before giving him a chance to display his talents, he took Jiang Mengmeng to the city, and the radio that fell into the water was in Jiang Mengmeng's hands.

Although it fell into the water, there is no major problem overall, and it can still be used when plugged in.

Jiang Mengmeng was lying on the stool, and the third-year book was thrown on the table, "Dabao, do you remember which book it is?"

Dabao shook his head, "I'm not a book reader, it would be nice if I can scan and record this thing."

Jiang Mengmeng:......So you said that you are the smartest Tongzi before, are you talking nonsense?

Jiang Mengmeng worked for a few minutes, and finally found it in the corner of the chemistry book that recorded the common sense of life. To be precise, it was someone else's notes.

The above records mix alcohol + white vinegar + baking soda, then pour it on the place where the screw is rusted, let it stand for a while, and then the screw can be easily unscrewed.

Jiang Mengmeng's eyes lit up, she ran downstairs, and shouted in a milky voice, "Grandma, grandma, where is the wine my grandpa hid?"

The old lady turned her head, "Why do you want wine?"

"Oh, slow down, put it down quickly, don't fall, it's all bought with money." The old lady quickly got up from the ground, and rushed to catch the baking soda and vinegar in Jiang Mengmeng's hand.

Jiang Mengmeng rubbed her head and looked around with her eyeballs, "Grandma, is grandpa's wine in the cabinet?"

Seeing Jiang Mengmeng's actions, the old lady thumped in her heart, "Hey, don't move the stool, the milk will help you."

The wine was taken down, but the old lady did not let go, "Mengmeng, how much do you want?"

Jiang Mengmeng blinked, grabbed the corner of her clothes, and pinched her little finger treacherously, "It's just a small cup."

The old lady nodded distressedly, took out a small cup, glanced at Jiang Mengmeng's little finger, and poured a small cup, which just wet the bottom of the cup.

Jiang Mengmeng:......

"Oh, there's not enough milk, pour some more." Jiang Mengmeng stomped her feet anxiously.

The old lady curled her lips, "Didn't you say that the little finger is a little bit smaller?"

Jiang Mengmeng pouted, "I also said a small cup, milk, I saw your hands shaking, let me do it."

The old lady rolled her eyes, "Come on, you six-year-old doll, why are you pretending to be an adult? If I drop my wine jar, who do I go to?"

Jiang Mengmeng stuck out her tongue and chuckled, "Pour more, please don't shake your hands."

The old lady just poured half a cup, and she refused to pour it out, and waited for Jiang Mengmeng angrily, "You just said that you are so stingy, why are you saying that my hands are shaking? I am not yet seventy or eighty, come on, stop making trouble, I won’t give it when I’m making trouble.”

Xu Cuihua held the wine jar in her arms, and stared at Jiang Mengmeng vigilantly, "I can't even ask your father."

That's right, her grandma has finished talking, Jiang Mengmeng carefully held the wine, then poured some vinegar, poured some baking soda, picked up the Wangcai dog brush and gently brushed the screws.

The old lady wondered, "You are both vinegar and wine, why do you want to fry the screws?"

Jiang Mengmeng covered her mouth and said cheerfully, "This is to dissolve the rust stains on the screws, so that I can twist them off."

Xu Cuihua was full of doubts, "Can this be done? Why didn't anyone say it before? I'm afraid it's not a bluff?"

Jiang Mengmeng was also curious, why no one used this method before?

Dabao curled his lips, "I used to not have enough to eat, how could I have extra money to buy wine and vinegar? Even if some people can buy it, they don't know how to do it."

Yes, Jiang Mengmeng slapped her forehead and told the old lady the reason.

Xu Cuihua was still dubious when she heard this, until Jiang Mengmeng unscrewed all the last screws, the old lady believed it.

"My dear, this method is very useful, but it is too expensive."

Jiang Mengmeng blinked, Fei?

Dabao thought for a while and nodded, it's worth it.

Jiang Mengmeng curled her lips, then she will find other ways in the future, otherwise, what can I do if my heart hurts?

The radio was completely disassembled. Jiang Mengmeng and Dabao worked closely together to analyze all the parts and dimensions within an hour. Even how to disassemble and how to install Dabao was clearly recorded in friendship.

Considering that taking things out of thin air would frighten her mother, Jiang Mengmeng lay down on the table and carefully copied the notes printed out by Dabaoxiang's printer.

Dabao sighed, "Mengmeng, when will you get a printer out? Then you can free your hands and ask me to work generously, no need to hide it anymore."

Jiang Mengmeng shook her head resolutely, "It's too expensive, Dabao. I only get one free point every time I pass one exam. Please ask for at least five. It's not worth it. I might as well ask Elder Niu to help me after school." As for me, I can give them extra lessons to earn some freedom."

Dabao choked, it seemed like this was true. He was afraid that Jiang Mengmeng would not invite him in the future, so Dabao immediately did not dare to say anything.

Jiang Mengmeng carefully compared each part, and after confirming that it was perfect, quickly assembled the radio, and finally plugged it in, um, it works.

"Grandma, I'm going to read a book."

The old lady held the radio happily, "Okay, okay, watch slowly, don't worry, I'm hungry and looking for milk."

After finishing speaking, he collapsed on the sofa, crossed his legs, and listened to the play slowly.

As soon as the old man entered the room, he heard the sound of babbling and singing, and his eyes lit up.

"Old lady, why did I hear someone singing?"

The old lady, who had stopped playing for an afternoon, turned off the radio, stood up holding the radio, "Well, you are old and deaf, and you heard it wrong."

Then he left the old man who threw away his self-doubt.

Jiang Minsheng scratched his head, and sat on the sofa in doubt, it's impossible, my ears are fine, and I'm not old yet.

"Hey, old lady, who did you say was old? Stop!"

Xu Cuihua ignored him, locked the door as soon as she entered the house, and then locked the radio in the cabinet.

Oh, the old man will definitely not be able to find it here, and she will take it out to listen to the opera when he goes out to play chess with the old man.

The old man who knocked on the door had no idea that his wife had planned his wife as an outsider in order to enjoy the good time to himself.

Well, my wife is, of course, my granddaughter.

Only the granddaughter knew about the radio at home.

As for Jiang Mengmeng, of course she wouldn't say, why, because she took the virtual materials given by Dabao, and she was researching a radio that could press the battery, record, and search channels.

Jiang Mengmeng directly dismantled her father's flashlight, and then changed the plug-in device. According to the high-frequency signal received by the antenna, she changed the voltage detection to 2 times to ensure that the signal can still be received even when the signal is weak.

Jiang Mengmeng was very conflicted, should I open my stomach for the radio?

Dabao scratched his head, "Be ugly. If you want to record, you must have a belly to install a blank cassette. Or, Mengmeng, don't want this function? What a waste of time."
