As soon as he got home, Han Feng immediately accompanied Vivian. As for Nala, she has her mother's family to take care of, and now her father and mother have also taken care of her. After all, it is their daughter, and some of her daughter's belly are the daughters of the family leader, naturally, they will take good care of Nala without being told by others.

The daughters-in-law that Han Feng brought from Tieliu City were already busy making lunch.

Han Feng accompanied Vivian, nor did he accompany her to do nothing.

For couples, it is not about doing nothing to talk to her, which is called accompaniment.

Han Feng is doing things at home, and his daughter-in-law sits next to him and watches, which is also called accompaniment. When the daughter-in-law sees him by her side, she will feel the same down-to-earth.

Han Feng is laying wires at home.

Brought back from Tieliu City, with ceramic insulated wires.

Han Feng climbed up and down.

Vivien must know that this is the electric light that Han Feng said.

However, after listening to Han Feng's explanation, she still doesn't understand what is called electricity.

She didn't know how electricity came from, how it was conducted through wires, or why the lights came on.

However, she knew that if the electric light that Han Feng said would be on, it would definitely be on.

She was looking forward to the lights coming on.

At night.

It's time to eat again.

As at noon, Freya, Styya and Sharon, and Sophia were all there, and Nala was here. Han Feng invited her here. Although she has her father and mother to take care of her, she can't miss the care of his husband.

In the afternoon, Han Feng was considerate and agreed that they would go back to Rog's camp to visit their father's daughter-in-law, Emily and Rachel, who also returned.

At this moment, he was also happy and excited to circle around Vivian.

When they heard that Vivien had it, they were happy and looked forward to when their bellies would be able to bulge in the same way.

Han Feng was busy doing the final test.

It's going to get dark.

Suddenly, in the roar of the machine, Han Feng's courtyard lit up, the family training ground outside Han Feng's courtyard also lit up, and the bridge of the small bridge also lit up.

The entire family suddenly screamed and screamed.

It was the children who were excited to shout for the light of this night, which was accustomed to the darkness of the night.

Han Feng did not enjoy this light alone, but extended the wire, and now it has extended to the small bridge and flowing water.

In the future, it will definitely continue to be extended, so that everyone can use electric lights at night and have light.

The lights are on, and Han Feng's daughters-in-law also feel magical.

Especially, when you eat at night, you can be in the yard and you won't feel dark.

Under such electric lights, eating, it feels even more unusual.

fantasized, in the future, they will all have children around their knees, under such a yard, under such lights, eating together, enjoying the shade together, playing games together, such a picture, thinking about it makes people feel warm and expectant.

"It's really bright, it's really bright, husband!" said Helvey.

Every time Han Feng proved that what he had said to her was not casually said and could be achieved, Hevier couldn't help but be excited.

Like Doris's daughter-in-law, who still has a childlike heart, at this moment, she has long been happy to play with the maid under the light.

Under the family training ground outside, there were also people standing who came to borrow light and take the children out for a walk.

Seeing that a small piece of the sky was lit up in the city, the residents of Sand Wolf City climbed the city wall curiously and stood on a high place to look at the place of the Wolf family.

They were all curious about how the Wolf family did it.

His efforts have begun to illuminate the family, and Han Feng himself can't help but be excited.

The world, with his efforts, has changed in a few months, just to catch up with the development of hundreds or thousands of years before.

Now, there will be trains, planes, electric lights, and soon, telephones and telegraphs.

Technology changes the world.

This world, I believe that in the future, it will be centered on Sand Wolf City, and huge changes will occur, and then it will affect the whole world.

"Han Feng, the electric light you made is really magical. Havier couldn't help but run to Han Feng again, pulled him, and went to see the magical generator.

She really couldn't figure out why this thing, as long as it turned, would be able to emit something called electricity, and then it could also light up the lamp, emit light, and illuminate the night.

I just don't understand it.

In the crowd of onlookers, there were also fools' mothers, Teresa, and Alan, and their youngest son. There is such a big excitement in the family, how can they not join in the fun.

Seeing Han Feng came up with a new gadget again, this new gadget is so incredible and magical, don't say I haven't heard of it before, even if you ask them to think about it, they can't think of it. Alan couldn't help but say to his wife, and when he had time, he really felt that they were the stupidest compared to their stupid sons.

These words made Teresa nod her head.

"Come, come, I've been trying all afternoon, but I haven't been able to get wires and lights into each of your homes. However, the husband gave you another thing, you can respond to the emergency first. Dada, what is this?" Han Feng smiled, brought a large wooden box, and took out one of the things inside to show them.

"What, what, husband, what is this?" the daughters-in-law all gathered around again with anticipation.

Han Feng said with a smile: "It's what I told you, it's a very bright oil lamp that can't be blown out by the wind." It's oiled inside. When you pump it into it like this, it will be very bright, even brighter than an electric light! ”

Saying that, Han Feng is a hands-on demonstration and teaches his daughters-in-law how to use gas lamps.

Under Han Feng's hands, sure enough, the oil lamp was getting brighter and brighter, and it was as bright as the sun, making it impossible to see it directly.

The daughters-in-law are all good at blocking their eyes.

However, the daughters-in-law were all very happy.

Because with this at night, I will never feel that a small oil lamp is lit in the house at all.

"Husband, since we have this, why do we need electric lights!" Hai Weier asked Han Feng with great concern.

Han Feng knew that Hai Weier would definitely ask questions, but it didn't necessarily have to be a problem. At this moment, having heard Hai Weier's question, Han Feng immediately explained to Hai Weier: "Because of the gas lamp, it also has its shortcomings. The downside is that you have to pump it in manually a lot. Otherwise, it won't light up. The electric light, on the other hand, can be placed there, and you don't have to ask, it can be left on all night. As long as the generator doesn't stop. The gas lamp is not good at this point. However, the gas lamp does not need to be arranged, it can be carried around by one person, and it can also be placed on the carriage as a horse lantern to illuminate, and it is even more convenient to use it for camping in the wilderness. You can't go out on an adventure in the wilderness, you can't carry a generator that big. So, gas lights are also useful. ”
