The three old men were quite well-behaved for the next half of the day. After sleeping, they got up, and played games. Someone came to install the door. After the installation, Yuan Qingling taught them how to unlock the lock, which can be fingerprinted and entered a password.

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

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

During dinner, Professor Yuan talked to them about Hong Lun and was very happy, but they always looked at Yuan Qingzhou secretly and saw that he was nothing. The three of them had a stable meal.

After dinner, Yuan Qingling decided to take them downstairs and make acquainted with the surrounding environment. At least, he knew that he would come back when he secretly went out.

After leaving the community and going to the nearby square, a group of aunts were dancing square dances. Whenever Yuan Qingling saw something that they thought they would think was fresh, he would explain it so that they would not be too curious and would further study it.

And they walked all the way, especially staring at the high wind lights.

After walking for half an hour, Yuan Qingling saw someone selling candy and fried chestnuts in front of him, and said, "I'll buy you some snacks. You can wait for me on the spot, don't go anywhere... Forget it, you can go with me."

The Supreme Emperor raised his hand, "No, you go, let's see who is a big god!"

Yuan Qingling corrected, "Square Dance!"

After thinking about it, it was okay to have a misunderstanding, so I went to buy chestnuts immediately.

As soon as she left, the chief assistant asked Xiaoyao Gong and the Supreme Emperor, "Why do you think those wind lamps are hung so high? Are they burning tin or tung oil? What are the lampshades made of? I see that they are different from the wind lamps on our side."

Xiaoyao said justice: "We also want to know this question. When we first came, we were hit by a carriage... and the road we were hit by a chicken carriage, there were many such lights. We wondered, what should we do if we light it so bright? Isn't it fuel? Or, we don't even need oil?"

The three of them looked at each other, then raised their heads in unison to look at the high street lights.

Yuan Qingling bought chestnuts and turned around and saw them staring at the street lights. He felt a thrill in his heart. He immediately paid the money and ran back with the chestnuts.

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

Eating chestnuts, the Supreme Emperor asked inadvertently, "By the way, are your cars expensive?"

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

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

"It's expensive, very expensive!" Yuan Qingling nodded heavily, at least, he had to be careful that they would remove another one. Moreover, at this time, he didn't know how to explain the principle of the car to them, because they did not admit to dismantling the car.

Their dignity and face must be maintained.

Forget it, when you take a taxi tomorrow, take the opportunity to tell them.

When I walked back, I had to ask Yuan Qingzhou to teach them to use a water heater. The three of them had never taken a bath in the hospital. Fortunately, the weather was cold and there was no problem not taking a bath for several days.

Yuan Qingling told his brother to understand, and to make sure that all three of them understand, otherwise, they would have to buy a water heater tomorrow, and even a water pipe would be exploded tonight.

Yuan Qingzhou felt that this would not be the case, because he had used tap water in the hospital. Although he had not taken a shower, he also washed his hands and wiped his face.

Two hours later, Yuan Qingzhou returned home exhausted. Yuan Qingling asked, "Are you all right? Are you sleeping?"

"I haven't been sleeping, I'm studying the crystal lamp." Yuan Qingzhou collapsed on the sofa, feeling his throat was so dry and hoarse. After taking a sip of water, he jumped up suddenly, "I forgot to teach them to make boiling water."

"I'll do it, I'll do it!" Yuan Qingling hurriedly stopped him, "You can take a shower and rest first. You have to go to work tomorrow. You can take some time at noon and go see the car. It's inconvenient to have no car."

"Okay, go!" Yuan Qingzhou really felt that he was not very good at speaking, so he asked Yuan Qingling to go.

This generation of ancient people is so hard to lead.

Yuan Qingling took the key and taught them to make water, and taught them to pay attention to power outages. They all learned it very seriously, and then it was the chandelier.

This crystal chandelier was left by the previous owner. It has an old style, but it is quite fresh and fun for the three giants. While turning on the lights constantly, two bulbs of the chandelier were burned out, and the brightness was not as bright as before, so they did not dare to do it again.

Yuan Qingling felt that he should explain the invention and principles of electricity to them. The three men sat upright and listened very seriously. If it weren't for Xiaoyao Gong's snoring, Yuan Qingling would think they were really interested.

The Supreme Emperor and Xiaoyao Gong fell asleep leaning on the sofa. The chief minister listened seriously. For Xiaoyao Gong and the Supreme Emperor, these are boring and there is no need to know the principles and processes, just know what they are useful.

The chief assistant insisted on understanding it. Through some explanation, we roughly understand that electricity is an energy source. After some devices, it can generate power, energy, and various kinds. Anyway, it is inseparable from it in daily life.

Yuan Qingling can finally make some popular science on the engine.

Many of them fly in the sky, run on the road, and run on the railway rely on engines to convert oil into kinetic energy. Naturally, there are new energy sources that use electricity. It is more comfortable to talk to the chief assistant because he is really smart, usually learns from one example and absorbs it quickly.

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

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

The next day, Yuan Qingling got up early and helped her mother prepare breakfast.

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

Their breakfast required pasta, so they cooked soy milk, steamed buns and buns, fried dough sticks, ordered a takeaway, ordered some snacks, and what they could eat.

Professor Yuan and the other three had to go to work after breakfast. Because there was no car today, they had to go out early to take the subway. After they left, only the three giants and Yuan Qingling had breakfast together.

The chief adviser asked Yuan Qingling, "Your brother... doesn't look like a person who is already a grandfather, he looks young."

Yuan Qingling was stunned, "What? Grandpa? He didn't even be a father and didn't marry his wife, so why did he become a grandpa?"

The chief minister glanced at the Supreme Emperor and Xiaoyao Gong indifferently. They were just concerned about eating and didn't hear it at all.

The chief minister asked again: "At this age, why haven't you got married yet? Look at your family background... it should be pretty good? Your brother looks good, why can't he marry a wife?"

Yuan Qingling smiled and said, "He doesn't want to be bound by marriage. It's great to say that being free is good."

"Yes, that's it." The Supreme Emperor nodded in agreement.

"That's because I haven't met someone I like." Xiaoyao righteous.
