On the night of the military wedding, the sickly beauty was pressed against the wall by the commande

The principle of the metal detector is very simple, use NE555 to build a pulse signal generator, which is used to generate a high-frequency pulse signal, which is supplied to the induction coil, and a magnetic field will be generated on the coil.

After knowing the principle, it will be very simple to do, and then prepare two potentiometers, one 2k is used to adjust the coil frequency, that is, the detection distance.

There is also a 100k to adjust the sensitivity, Li Xin connects these things little by little, and then it is enough to test and adjust the small details.

It didn't take long for Li Xin to make this small metal detector, hide a piece of metal in the cabinet, and sweep it with the detector, and after a while, there was a sound.

Li Xin made it very small, he could hold it with one hand, and after the test, Li Xin made his appearance more exquisite, and left the space with it.

Seeing that the time was not early, Li Xin put away the detector he had just made, and took Sanmao back into the space.

The tea was still on the table before, and Sanmao had been hot, and even now, the tea is still hot.

Li Xin drank a few sips, put away the tea set, and was about to wash vegetables and cook, when he suddenly remembered that He Beichen's bed sheets and quilt covers were still drying in the yard.

He Beichen came back from outside, and when he walked into the compound, he saw a familiar figure, and he walked over with a turn of footsteps.

This sheet, if he's not mistaken, should have been on his bed.

"I haven't slept for a few days, why did I wash it?" He Beichen reached over and took the sheet from Li Xin's hand.

Li Xin was startled by his sudden appearance, and let go of the hand holding the sheet, if He Beichen hadn't picked it up, he might have fallen to the ground.

"Wash and clean up often, and the sun is fine today. Li Xin watched He Beichen take the sheets and quilt covers, and then came back to his senses and explained.

Although she just walked into his room in a daze, she dismantled and washed it, but she still remembered that in her previous life, she often saw complaints that boys would dye the bed when they slept, and it must be good to wash it quickly.

He Beichen didn't care, thinking that after coming from Li Xin, the house was always very clean, and he felt that Li Xin was still quite diligent.

When the two of them returned home, Li Xin took the sheet from He Beichen's hand and prepared to re-lay it.

He Beichen didn't enter the kitchen, but walked in with Li Xin and watched her spread the sheets.

Li Xin looked like he was in a good mood, he looked at it, and felt a little unhappy in his heart.

"Li Xin. He Beichen stepped forward and called her.

"What's wrong?" Li Xin looked at him suspiciously, unable to understand why He Beichen didn't go to the kitchen to cook, but followed her in.

But it's good to come in, and it's faster for two people to make a bed together.

Li Xin didn't wait for him to answer, he picked up the corner of the sheet and handed it to him.

"That's right, the two of us are on one side, and I don't have to run around if we pull it together. Li Xin instructed him.

He Beichen held the corner of the sheet in his hand, but after Li Xin walked to the bed, he was still standing there and didn't move at all.

"He Beichen, what are you doing?" Li Xin tugged for a moment, and looked at He Beichen in confusion.

"The bed was too hard and the slats were uncomfortable. He Beichen came back to his senses and glanced at the bed with disgust.

At this time, the bed has not been made yet, there is only a hard bed board, and the more He Beichen looks at it now, the more he feels that this bed is not pleasing to the eye.

Li Xin listened to He Beichen's words and looked at the bed in front of him blankly.

She had only removed the sheets and covers, but she didn't care that there was only a hard bed board on it, not even a thin layer of cushions.

He Beichen has slept for so long, and he has never had a mat, how did he sleep before?"

"I'll go get a bed of cotton wool and put it on for you." Li Xin let go of the sheets in his hand and prepared to go back to the room to move a bed of cotton wool.

Li Xin remembered that there were two beds of cotton wool in the cabinet in her room, and if she moved a thicker bed, she shouldn't feel hard after putting it on.

I don't know if He Beichen likes to sleep softly, if you want to be softer, you can move both beds over.

He Beichen saw that she was really going to move the cotton wool, and when Li Xin passed by him, he grabbed Li Xin and didn't let her leave.

Li Xin was suddenly pulled, feeling that He Beichen was very strange today, since he came back from collecting the sheets just now, he has been very strange, and he doesn't know what He Beichen is thinking.

"Are you going to move it yourself?" Li Xin asked, looking at him.

"I don't want to sleep in this bed anymore. He Beichen looked at Li Xin's eyes and said directly.

Last night, He Beichen reflected on Li Xin after sending him back to the room.

He was sure of one thing, now he really wanted to share a bed with Li Xin, instead of sleeping in separate beds like now.

But this matter was brought up by him before, and he didn't think about how to mention the matter of sharing a bed with Li Xin before.

But Li Xin washed his sheets and quilt covers at this time, and He Beichen suddenly felt that this was a good opportunity.

Li Xin was stunned, she finally knew now why He Beichen was acting so strangely just now.

What do you say about the bed board is too hard, I haven't seen it for so long before, and I want to move in with her.

Li Xin immediately saw He Beichen's intentions, but before He Beichen said that he wanted to divide the room, she told him to go back to sleep and not go back.

"If you don't want to sleep here, you can sleep on the sofa. Why don't I lay the floor for you in the living room?" Li Xin suddenly raised his head and looked at him with a smile on his face, his eyes full of cunning.

She didn't want to agree to He Beichen so easily, and even looked at him and had two teasing intentions.

He Beichen looked at Li Xin's eyes with burning eyes, and Li Xin's emotions that he did not hide made him see very clearly.

He suddenly threw away the sheet he was holding, and his eyes were suddenly full of aggression like a wolf that had seen its prey.

"Ahh

He Beichen suddenly picked her up just now and walked towards the outside of the room.

"He Beichen, what are you doing, the bed hasn't been made yet!" Li Xin kicked her legs, trying to get He Beichen to put her down.

But He Beichen acted as if he hadn't heard it, and walked quickly to the next room with her, and put Li Xin on the bed in the master bedroom.

He didn't get up, his hands were supported on his sides, and Li Xin was encircled in the middle, his eyes always staring at Li Xin's eyes.

"I'm going to sleep here. He Beichen's voice was low, strong and domineering.

In this posture, Li Xin felt the burning breath on He Beichen's body, and three words suddenly appeared in his mind: forced love.

"Huh", Li Xin's face blushed completely.
