The old man was more well-behaved for most of the next day, slept a little, played games after getting up, someone came to install the door, and after the installation, Yuan Qingling taught them how to unlock the lock, they could fingerprint, and they could enter the password.

This is not difficult to teach, but after teaching, Xiaoyao Gong suddenly stared at the combination lock and asked, "What is here?" ”

Yuan Qingling looked at him with interest, and the other two also leaned over to star, her head hurt even more.

During dinner, Professor Yuan had a high talk with them and talked very happily, but they always secretly looked at Yuan Qingzhou, and seeing that he was casual, the three of them could be regarded as having a stable meal.

After dinner, Yuan Qingling decided to take them down for a stroll to familiarize themselves with the surrounding environment, at least, to know the way back when they went out secretly.

Out of the community, to the nearby square, there is a group of aunts dancing in the square, Yuan Qing Ling Danfan saw something that they thought would be new, and explained it, lest they be too curious and would study further.

And they watched all the way, especially staring at those high wind lanterns.

After walking for half an hour, Yuan Qingling saw someone selling sugar and fried chestnuts in front of him, so he said: "I'll buy you some snacks, you wait for me in place, don't go anywhere...... Forget it, you can go with me. ”

The Emperor raised his hand, "No, you go, let's watch people dance a big god!" ”

Yuan Qingling corrected, "Square dance!" ”

After thinking about it, it was okay if I misunderstood, so I immediately went to buy chestnuts.

As soon as she left, Shoufu asked Xiaoyao Gong and the Emperor, "Why do you say those wind lanterns are hanging so high?" Is it fire oil or tung oil? What is the lampshade made of? I don't think it's the same as the wind lanterns over there. ”

"We also want to know about this question, we just came here and were ...... by the carriage The road that was hit by the chicken cart has a lot of such lights, and we also wondered, what are we doing with such a light on? Doesn't it cost oil? Or maybe you don't even need oil? ”

The three of them looked at each other for a moment, and then looked up at the tall street lamp.

Yuan Qingling bought chestnuts, and when he turned around and saw them staring at the street lamp, he sighed in his heart, and immediately paid the money and ran back with the chestnuts.

It is indispensable to popularize the street lamps and solve their doubts, otherwise, I am afraid that the street lamps in this square will be demolished by them when they get up tomorrow.

Eating chestnuts, the Emperor Taishang casually asked, "By the way, are your cars here expensive?" ”

Yuan Qingling raised his eyebrows and glanced at him, "Why do you ask that?" ”

"Ask." There was no weakness on his face.

"Expensive, very expensive!" Yuan Qing nodded heavily, at least, he had to prevent them from dismantling another car, and at this time, he didn't know how to explain the principle of this car to them, because they didn't admit to dismantling the car.

Their dignity and face must be maintained.

Let's wait until tomorrow when I take a taxi out, and then take the opportunity to talk to them.

Walking back, I had to let Yuan Qingzhou teach them to use a water heater, they had never taken a bath in the hospital, but fortunately, the weather was relatively cold, and there was no problem if they didn't take a bath for several days.

Yuan Qingling told his brother that he must teach it clearly, and he must understand it to all three of them, otherwise, he will have to buy a water heater tomorrow, and there is even a high chance that the water pipe will burst tonight.

Yuan Qingzhou felt that this was not enough, because he also used tap water when he was in the hospital, and although he did not take a bath, he also washed his hands and wiped his face.

Two hours later, Yuan Qingzhou returned home exhausted, and Yuan Qingling asked, "Are you all right?" Did you sleep? ”

"I didn't sleep, I studied the crystal lamp." Yuan Qingzhou collapsed on the sofa, feeling that his throat was so dry and hoarse, and after taking a sip of water, he jumped up suddenly, "I forgot to teach them to boil water." ”

"I'm coming, I'm coming!" Yuan Qingling hurriedly stopped him, "You take a shower and rest first, you have to go to work tomorrow, you take time at noon, let's go and see the car, it's inconvenient to have no car." ”

"Okay, there you go!" Yuan Qingzhou really felt that he couldn't speak, so he let Yuan Qingling go.

This year's ancients are so difficult to bring.

Yuan Qingling took the key and went over, taught them to boil water, taught them to pay attention to power outages, they all studied very seriously, and then it was the chandelier.

This crystal chandelier is left by the previous owner, the style is relatively old, but for the three giants, it is still relatively fresh and fun, in the process of constantly turning off the lights and turning on the lights, two bulbs of the chandelier burned out, and the brightness was not as good as before, so they did not dare to get it again.

Yuan Qingling felt that he should explain the invention and principle of electricity to them, and he sat upright and listened very carefully, if it wasn't for Xiaoyao Gong snoring, Yuan Qingling felt that they were really interested.

The Emperor and the Emperor Xiaoyao fell asleep on the sofa, Shoufu listened really carefully, for the Emperor and the Emperor, these are boring, you don't need to know the principle and process, just know what the use is.

Shoufu still insists on getting it clear, and through some explanations, I roughly understand that electricity is a kind of energy, and after some devices, it can generate power, energy, all kinds of things, anyway, in daily life, it is inseparable from it.

Yuan Qingling can finally popularize the engine.

Flying in the sky, running on the road, running on the railway, many of them rely on the engine to convert oil into kinetic energy, naturally, there is also a new energy source that uses electricity, and it is more comfortable to talk to Shousuke, because he is really smart, usually inferences, and quickly absorbs it.

After hearing this, he sighed heavily, "It turns out that this machine is not that chicken, no wonder ......" No wonder I can't find it.

At two or three o'clock in the morning, Yuan Qingling woke up the Emperor Taishang and Xiaoyao Gong, asked them to go into the room to sleep, and took them to see the car tomorrow.

The next day, Qing Ling got up early in the morning and helped her mother Zhang Luo have breakfast.

She felt that after the operation, she was in good spirits, and even if she only slept for two or three hours, she did not feel sleepy at all.

They needed pasta for breakfast, so they boiled soy milk, steamed steamed buns and steamed buns, fried fried fritters, ordered takeout, ordered some dim sum, and whatever they ate.

Professor Yuan and the three of them had breakfast and were going to work, because there was no car today, so they had to go out early to take the subway, and after they left, the three giants were left to have breakfast with Yuan Qingling.

Shoufu asked Yuan Qingling, "Your brother...... It's not like someone who has become a grandfather, looking young. ”

Yuan Qing Ling was stunned, "What? Grandfather? He didn't even be a father, and he didn't marry a daughter-in-law, so how could he be a grandfather? ”

Shoufu glanced at the Emperor Taishang and Xiaoyao Gong lightly, they only cared about eating, as if they didn't hear it.

Shoufu asked again: "It's all this age, why haven't you married yet?" Look at your family background...... Shouldn't it be okay? Your brother's character looks good, why can't he marry a daughter-in-law? ”

Yuan Qingling said with a smile: "He doesn't want to be bound by marriage, it's good to say that a person is free." ”

"Yes, that's right." The Emperor nodded approvingly.

"That's because I didn't meet anyone I liked." Get away with it.

"Boring!" The Emperor Taishang is not very interested in this topic, for a person who has never experienced love much in his life, it is really boring to say this, and he doesn't like to listen to it.
