Generally speaking, if one person asks another person what he can do, it means that he himself does not know what he can do, or that he cannot do what he wants to do alone. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

But apparently Ye Dai didn't plan to match it all, so she glared at him and asked, "If you want to say it quickly, I'll also go down to help." ”

Ding Chen sighed, and said in his heart, "Sister, you are so serious, aren't you afraid of scaring your boyfriend away?" ”

But the problem now is that the girl doesn't want to run, and of course Ding Chen can't let her run. So Ding Chen couldn't do what he liked to do the most, so he could only choose one of his favorite things to do among the things he could choose.

He rubbed his hands together and said, "Let's continue." ”

"Not waiting for Carlo?" Ye Dai looked at him suspiciously and said, "She really wants to see it." ”

"First of all, she's actually just watching the fun." Ding Chen said: "Second, if you fail, it is enough for you to know alone. ”

Ye Dai suddenly realized, whether Carlo is a layman or not, it is obvious that Ding Chen cares more about the latter reason. Thinking of this, she couldn't help laughing, and said to Ding Chen: "Why don't I go down to help, okay, you can call us." ”

"No, you don't." Ding Chen waved his hand and said, "You are not an outsider. ”

Ye Dai glanced at him and did not deny it. Just urging Ding Chen to hurry up.

Ding Chen connected the exposed bare wires on the battery cover according to the polarity, and finally divided into two strands. Then connect them to the two terminals of the LED lights.

LED beads are essentially light-emitting diodes, which are polar limited, forward conduction, reverse cut-off, so the positive and negative poles cannot be reversed. And there is a pressure limit

Ding Chen does not have a multimeter in his hand, but he can distinguish the positive and negative poles according to the pin length of the light-emitting diode, so as not to be mistaken.

Most of Ye Dai's skill points are in chemistry, and the rest are made up for the mechanical foundation, and there is basically a blank in electricity. This is also a disadvantage of the mentorship system, and in the absence of additional information, students who do not know the tutor will not be able to. Ye Dai's father has no achievements in electrical engineering, so it is naturally impossible to teach Ye Dai.

So although she knew what Ding Chen was doing, she didn't know what to do. Seeing Ding Chen looking at the LED light motionless after connecting the wire, he couldn't help but ask in a low voice, "What else do you want to do?" ”

Ding Chen looked at the unchanged LED light, sighed, and did not answer Ye Dai's words. Even if the migration rate of electrons is slower than their own travel, there should be an electric current at this time.

However, he was not discouraged, and after rechecking the wiring and making sure that it was not reversed, he simply opened the lampshade and unplugged the light-emitting diodes plugged into it from the lamp holder one by one.

As he moved, the light bulb left on the plugboard suddenly glowed faintly. Ye Dai exclaimed in surprise. Ding Chen's subordinates continued to pull out LED beads. The withstand voltage curve of LED is very strange, and it is not resistant to a wide voltage, and in the absence of resistance adjustment means, he can only rely on the resistance of the LED beads themselves to form the optimal circuit.

When the light emitted by the electric beads left on the lamp finally reached the intensity in Ding Chen's memory, he breathed a sigh of relief, and turned around to find that he didn't know when, Ye Dai had already extinguished the oil lamp and was staring at him in the faint blue light.

Ding Chen subconsciously touched his face and smiled at Ye Dai: "What's wrong?" Didn't wash it just now? ”

Ye Dai stared at Ding Chen's face that looked deep under the cold light source, and said softly, "No." ”

Ding Chen sighed, turned his head to look at the bright electric lamp in front of him, rubbed his hands with satisfaction, and said with a smile: "In the electric era, I'm back again." ”

Then he found Ye Dai standing beside him and didn't make a sound, glanced at her suspiciously, and found that her face was confused, her eyes were staring at him motionless, and he was suddenly startled, stretched out his hand and shook it in front of her, and said in a low voice: "Hey, are you okay?" ”

Ye Dai blinked, quickly returned to normal, shook her head, and said, "I'm fine." ”

"Are you all right?" The light of the LED lights is quite strong, and the blue light fills the room, although because of the angle, there is no way to make everything visible, but it is still easy to see the tears flowing on Ye Dai's face.

It is said that men don't guess what girls are thinking, but it's not that they don't guess, but they can't guess it.

Ding Chen has never added this talent point since he was a child, and naturally it is impossible to guess why Ye Dai is crying, and said in his heart that you are like this when you look at an electric light, so if the blind man sees the light again, he will not be able to amnesty the world?

He has never walked the routine of a warm man, and there is no way to find chicken soup at this time, so he had to pretend not to see the tears on Ye Dai's face, stretched out his index finger and raised it in front of Ye Dai, and asked, "Is it really okay?" How much is this? ”

Ye Dai quickly raised her hand to wipe the tears on her face, patted Ding Chen's hand away, looked at Ding Chen's worried gaze, sighed, and said in a low voice: "I thought of my father just now." She said, "Every time he does something, the smile on his face is exactly the same as the one you just had." ”

Ding Chen was stunned for a moment, and then he understood why Ye Dai suddenly burst into tears. Think about it, according to Ye Dai, the apartment left the era of electric energy in the past few years, which should be about the same time as her father's death, and it is impossible to be so excited to watch an electric light. But if her father is remembered, then it is understandable. Although Ye Dai has always been reluctant to mention her father, it can be seen from her hatred of Xu Shuidong that her father's status in her heart is definitely not as low as she said.

He thought for a while, slowly opened his arms, and said to Ye Dai: "If you want to think about it, I can lend you a strong arm to use." ”

Ye Dai looked at him fixedly, and only after a while did she smile and scolded in a low voice: "At this time, you haven't forgotten to take advantage of me?" ”

"The conscience of heaven and earth." Ding Chen said aggrievedly: "I'm an innocent and kind person, definitely not as bad as the old K madmen and them, so they can compare with me." ”

Ye Dai ignored his nonsense, looked at his outstretched arms, sighed, took a step forward, slowly reached out to hug him, put his head on Ding Chen's shoulder, and said quietly: "Since you sincerely invited, then I will reluctantly borrow it." ”

Ding Chen smiled lightly, thinking about how this word sounded familiar.

He carefully lowered his arms, hugged Ye Dai's waist, and pondered very seriously in his heart, is this considered a first base? Or, do you want to take the opportunity to go straight to base?

There was a jumble of hurried footsteps, and the door slammed open. Ding Chen was shocked, he could have pushed Ye Dai away in time, but unfortunately the feeling of nephrite in his arms was rare to enjoy, and his movements were half a beat slower, and he was immediately caught red-handed.

Outside the door, Carlo slammed in and shouted, "What's wrong, what's wrong?" What's wrong......"

Then she looked at the two people hugging each other in a daze, and suddenly stopped, her big eyes full of surprise.

Her gaze swayed on the electric light and the two people, and then she clapped her hands and smiled: "Brother Ding, have you finally stripped naked?" ”

Ding Chen felt that Ye Dai in his arms struggled violently, so he had to let go of his hands. Ye Dai immediately broke free from his arms, and her face was as ashamed as a red scarf. She didn't dare to look back at Ding Chen, walked a few steps quickly, bypassed Ding Chen and stood in front of the window, thinking to herself that Ding Chen was thick-skinned anyway, let him deal with this scene. Then she let out a whoop and let out a scream.

Ding Chen didn't pull the curtains, so he could see out the window directly. I saw that in the open space downstairs, a crowd of black people gathered, and people kept running out of the building to join the ranks. Everyone looked up at her, with a pious and single-minded expression.

Ye Dai realized that the light in the room was too strong, and outside the sun setting, the people outside the building could easily notice the strangeness in the room, and it was no wonder that Carlo would appear in time, a picture of Xingshi asking for guilt. clearly guessed that Ding Ye and the two of them did not wait for her.

Downstairs, seeing Ye Dai appear in front of the window, I don't know who took the lead, suddenly applauded, and someone shouted: "Ye Dai, well done, worthy of being your father's daughter." ”

I don't know if it was in response to this lively scene, but in the shadows in front of the building, a donkey with a loud voice also barked and drank and harmonized with the man's voice.
