My school sweetheart

Xu Lang shook his head helplessly with a wry smile, "wife, do you really want to kill me? How can this kind of electrical equipment work without electricity? "

Xiao yuruo said with a smile: "hee hee, my husband is very good. I'm optimistic about you. To remind you, you've wasted a minute."

Since the wife wants to play, it's worth playing with her. Even if she fails, it's worth making her happy.

Xu Lang quickly lifted the quilt and got out of bed. However, he was not dressed yet.

"Ah Xu Lang, why are you so shameless that you don't wear clothes in broad daylight! " Xiao yuruo turns around in a hurry and doesn't look at Xu lang. her face turns red with shame.

Xu Lang is a face of injustice, said: "wife, you take the initiative to break into my room is not good, I sleep always do not like to wear clothes."

Xu Lang said as he took his pajamas and put them on.

Xu Lang didn't think much. He put on his pajamas and went out. He needed to prepare some props.

When Xu Lang put on his clothes, Xiao yuruo said, "now, you only have six minutes left."

Xu Lang was very helpless and ran out in a hurry.

But Xiao yuruo cried at the back, "Hey, why are you going? Don't ask your subordinates to help you buy batteries, and don't use any live equipment! "

"I know. I'm sure I won't foul." Xu Lang said, then ran down the stairs.

Xu Lang doesn't think much about it any more. No matter how busy he is today, he has to make his wife happy. Besides, he has nothing to do. If he is busy, only Ouyang Feifei's elder sister is there. She is under the care of her subordinates. Last night, she suffered a lot. Xu Lang is really worried. However, his current task is to make his wife happy and take care of her at night Sister.

Thinking about this, Xu Lang ran into the kitchen in a hurry. Fortunately, he found two ready-made potatoes in the refrigerator. Then he found two wires and quickly ran upstairs to the room.

Xiao yuruo thought that Xu Lang could find out what kind of advanced alternative materials, but when she saw the two potatoes in his hand, she could not help laughing. Finally, she could rest assured and said with disdain, "husband, are you crazy? What about two potatoes? "

But Xu Lang didn't speak much. He quickly came to his desk, picked up the alarm clock that stopped working because the battery was dead, took down the No. 7 battery that was dead, and used Shaolin '.

Seeing that Xu Lang is doing some incomprehensible actions, Xiao yuruo, who is next to him, stands on one side curiously, looks at it carefully and asks, "husband, what are you doing?"

However, time is pressing, and Xu Lang doesn't have much confidence. He can only try it according to the principle of electricity conduction and power generation. He really wants to win over his wife. It's a rare chance to kiss me with his wife on a beautiful weekend. There is no one at home. It's really a rare opportunity.

Xu Lang inserted the copper and zinc into two potatoes, and then connected them with two wires.

Of course, the wire should be connected to the positive and negative poles of the alarm clock, and the copper and zinc chips inserted in the potato are the positive and negative poles. With the wire connection, in a moment, a miracle appears.

Xiao yuruo gaped at the alarm clock and started to work normally!

God, how could it be? What's going on?

Xiao yuruo didn't have time to think about winning or losing. She was completely shocked by this incredible scene. Even when the magician was doing magic, Xiao yuruo was never so surprised. How could it be realized?

"Husband, how did you, how did you do it?" Xiao yuruo asked.

Xu Lang said with a smile, "wife, don't ask me how I did it first. Tell me first, have I violated the rules?"

Xiao yuruo shook her head hastily, "No."

Xu Lang quickly asked, "did I win?"

Xiao yuruo hesitated for a moment. Although she didn't want to admit it, it was true after all. She had to nod her head! You win, but you have to tell me what's going on? "

Xu Lang laughs, which explains the principle.

It turns out that in some fruits, there are acidic liquids. Acidic liquids are conductive media. With copper and zinc chips, there are positive and negative electrodes and positive and negative ions. Positive and negative ions play a role in the acidic liquids found in potatoes and form qualitative movement. Naturally, "electricity" is generated. Then, wires are connected to the alarm clock, and "potato battery" is formed ”Two potatoes can drive the alarm clock to work for more than a week without decay. If the two potatoes can never decay, the power supply time will be greatly improved.

After listening to Xu Lang's story, Xiao yuruo stares at Xu Lang in a daze, "husband, are you human?"

Xu Lang rolled his eyes. "Of course, it's human. It's nothing. My biggest specialty is not that. It's that I can make little people. Honey, if you lose, let's start making people."Xiao yuruo finally came back to her senses and quickly turned to leave.

However, Xu Lang was not willing to let her go. He took Xiao yuruo in his arms and threw him on the bed. "Hey, wife, I'm willing to accept defeat. Now, I'm starting to play my best skill, that's making little people!"

Xiao yuruo screamed in a hurry: "no, I have to prepare for a month. What I just said is to use a set, but I didn't promise you to make a little man."

Xu Lang a burst of helpless, "good good, with the set."

Xu Lang had to take out a condom.

Xiao yuruo sat up and asked, "husband, how do you use this thing?"

Rarely interested in his wife, Xu Lang patiently told his wife about it, took one out of it and opened it.

Xiaoyuruo is a grab in the past, hard set in Xu Lang's head, "promise, I fulfill my promise, has used one."

Xiao yuruo said as she ran out, faster than the rabbit.

Even though Xu Lang was petrified on the spot, he didn't come back for a long time.

Startled for a long time, also at this time, the mobile phone rang, Xu Lang listlessly to answer, "Hello, who?"

There is the chirp of a large group of girls came to the laughter, babbling said: "I'm pregnant!"
