Chapter 397 How did he do it?

After subduing Wu Yunwan, Lu Chen stopped going to her room every night. He was busy playing grassland riding games with Xiao Wenyao and Yelu Nanyan these days.

To be honest, Lu Chen almost wanted to give up on letting Yelu Nanyan or Xiao Wenyao conceive their children. After trying for so long, their stomachs showed no reaction at all.

Lu Chen was wondering if he had become a pseudo-celestial being, so the difficulty of getting pregnant had increased again. Chu Yuqin was able to get pregnant in one go, but why couldn't other women, and Wang Qingci, a stubborn person who didn't want to get pregnant, was captured. However, Yelu Nanyan and Xiao Wenyao, who were the most cooperative, could not.

Lu Chen even planned to let Mu Zixuan and the others try again. Although Mu Zixuan, Zhou Youyou, and Zhou Xiaoxiao have all become warriors, their levels are still relatively low, and they are still in the stage where it is easier to get pregnant. If all three of them are pregnant, , then it has nothing to do with yourself.

If the three of them are not pregnant, it proves that entering the pseudo-celestial realm has indeed made it much more difficult for him to conceive a child. If he wants to have children in the future, he will have to spend more effort.

After a period of verification, neither Mu Zixuan nor Da Zhou Xiao Zhou was pregnant. Lu Chen basically clarified the reason. Sure enough, it was not the problem of Yelu Nanyan and Xiao Wenyao, but because he had broken through to the realm of pseudo-celestial beings, so It becomes more difficult for them to carry children.

Lu Chen didn't have a good solution for the realm's restriction on births. Finally, Lu Chen decided to ask the system to see if it had any good solutions.

In the evening, Beiwang Mansion.

Today, the entire Beiwang Mansion was quite busy. Lu Chen stood in Fengyun Courtyard and watched the servants going about their business.

At this moment, except for Wu Yunwan and Murong Xueer, Lu Chen's wives and concubines in the inner courtyard were basically gathered in Fengyun Courtyard.

Today is a special day, a day of electricity.

Lu Chen and the others have already developed light bulbs and set up circuits. There has been a lot of movement in the palace these days, and craftsmen are busy setting up wires every day.

Building electric wires was a big project. There were no rubber or plastics in this era. Although Lu Chen had obtained the drawings of the gasoline refining process, there were no conditions for the development of the petroleum industry in the current Northland.

Lu Chen actually set up a resource exploration department to let them explore for resources such as oil and coal.

It's just that what that department has discovered now is basically coal mines, or iron ore and copper resources. It's still difficult to find oil.

To find oil, you have to drill, but drilling is difficult. In the final analysis, there is no such condition.

Without rubber and plastic, we have to find a way to replace the insulator with something else. Under the current conditions, the best insulators are glass and ceramics.

For the sake of beauty, Lu Chen finally chose ceramic tubes. During this period, the ceramics workshop in Beiwangfu worked overtime almost every day to make ceramic tubes, just to lay circuits for Beiwangfu.

Originally, it would take half a day to lay the ceramic pipes, but Lu Chen saw that there was not much work left, so he worked overtime tonight to let the craftsmen finish it. He couldn't wait to bring Beiwang Mansion into the electrical age.

I use candles every night. Not to mention the dim light of the candles, and there is still some smell.

As a time traveler, Lu Chen couldn't stand the days of lighting with candles.

Lu Chen stood in the yard and watched, while his wives and concubines gathered around the craftsmen outside with great curiosity, watching them check the circuits and install the light bulbs.

They had already heard Lu Chen talk about generators and lights while they were eating. At that time, they felt very incredible. This was the first time they had heard that electricity could be tied up and used.

After Lu Chen glanced at the busy crowd, he said to the system in his heart: "System, if the higher my realm, the less likely it is to give birth to children, then when I break through to the realm of heaven and man, or a realm higher than the realm of heaven and man, Isn’t your system useless?”

[The host's worries are unnecessary. Even if the host breaks through to the heavenly realm, or even becomes an immortal, the host can still make his wife and concubines pregnant, but the probability is small. Of course, this world cannot bear a real immortal. 】

Lu Chen frowned when he heard the system's answer. Although the system said so, he had already proven through practice how difficult it is to have a child now.

It was already so difficult for him to give birth to an heir when he was still a pseudo-celestial being. When he breaks through to the realm of celestial beings, won't the difficulty increase by an order of magnitude?

No, he had to make as many babies as possible while his realm was still relatively low. Thinking of this, Lu Chen glanced at the delicate bodies and buttocks of his wives and concubines in the yard.

It seems that before becoming a heavenly being, I have to work harder.

Just when Lu Chen was distracted, Mo Xing came to Lu Chen's side and said, "Your Majesty, all the circuits have been tested and can be officially powered on."

Hearing this, Lu Chen came back to his senses and said immediately: "Okay, get ready to power on!"

At this time, Mu Zixuan and the others also returned to Lu Chen. Chu Yuqin curiously looked at the glass-like objects pressed against the door and smelled: "Chen'er, can this thing really light up?"

Lu Chen said with a smile: "Just wait and see, it will light up soon."

Having said this, Lu Chen said to Mo Xing: "Start with the third power supply, switch on and off every three breaths!"

Although this small amount of electricity cannot harm high-level warriors, and even has basically no harm to grandmaster-level warriors, for ordinary people in this world, electricity can still electrocute people to death.

After hearing Lu Chen's order, Mo Xing said excitedly:

"Yes, Your Majesty!"

They are witnessing history, as Beiwangfu will become the first household to use electricity.

As the first power transmission began, all the lights in Beiwang Mansion turned on.

Seeing this scene, the girls instantly exclaimed. Not only them, but the entire palace's servants, maids, and even the guards were frightened by the sudden light.

For a time, the entire Beiwang Mansion became as bright as day.

Although Lu Chen had asked people to remind the people in the palace from the beginning that the light bulbs would emit bright light tonight, so that they would not be too surprised, but hearing it from others and seeing it with your own eyes were completely different.

They thought that these "glazed lanterns" were as bright as lanterns at most, but they didn't expect them to be so bright. This made them feel that Beiwang Mansion was no different from the daytime.

However, the light quickly disappeared again. Seeing that the light suddenly disappeared, everyone looked confused.

Xiao Wenyao asked curiously next to Lu Chen: "Your Majesty, why are those glazed lamps not lighting up? Is there something wrong?"

Lu Chen said with a smile: "No problem, I deliberately cut off people's power. Although these household electricity cannot cause much harm to high-level warriors, it is still possible to electrocute ordinary people, so be sure to use it when turning on the power. Turn it on and off three times to avoid anyone getting an electric shock from direct contact with the wire."

Hearing Lu Chen's words, the girls instantly realized that Lu Chen had thought so carefully.

Not long after Lu Chen finished explaining, the lights in the palace turned on again, and then went out again a moment later. It was not until he got up at home after the third time that the lights in the palace went out again.

Seeing the courtyard illuminated by the glazed lamp as if it were daytime, Chu Yuqin couldn't help but sigh: "I didn't expect that I would be able to see such a wonder in my lifetime!"

Mu Zixuan asked next to Lu Chen: "Your Majesty, will the people in the North be able to use electricity in the future?"

Lu Chen replied: "Of course, it's just that it takes a long time to make the machines for power generation and create the conditions required for power generation."

"But within a hundred years, there will be no problem in providing electricity to the entire Northern Kingdom, and even to the people of this world."

Hearing Lu Chen's answer, all the girls fell into silence. With electricity, the world will become more beautiful in the future, and the nightlife will be richer in the future.

Lu Chen said: "Okay, you all should go back and rest. It's already so late."

After hearing Lu Chen's words, the girls gradually left Fengyun Court and returned to their own residence.

But they were destined to have trouble falling asleep tonight, after all, the shock brought to them by the glazed lamp was too great.

After all the girls went back, Lu Chen looked at Mo Xing not far away and asked, "How long is the lifespan of this electric lamp now?"

Although the materials used to make electric lamps have changed, the lifespan is still not good. In addition, there is no vacuum inside the electric lamp, so the lifespan of these bulbs is still not particularly long.

Mo Xing replied: "Back to your lord, the current lifespan of these lamps is about seven days, but if the air inside can be extracted, then the lifespan of these lamps should be extended to several months. Several of the lamps we used in the experiment that extract the air It's still on now, and there's no sign of burning out at all, but it's a little difficult to make such an electric lamp."

Today's electric lamp production relies on manual work. The air inside the glass must be completely removed. The person who makes the light bulb must be at least a half-step master. If he can release the true energy to the outside, he can make such a light bulb.

Of course, this is what hand-making is like. They don’t have much experience yet. When the technology matures and they have experience, ordinary people may also be able to make vacuum bulbs.

Lu Chen thought for a while and then said: "Just seven days, just replace it in time."

It's just a trial now, so there's no need to worry too much about how long the light will stay on.

Lu Chen then said to Mo Xing and other craftsmen: "Okay, you all have worked hard. Go back and have a good rest tonight."

Mo Xing and all the craftsmen said in unison: "Thank you, Your Majesty!"

As soon as he finished speaking, Lu Chen asked the guards waiting outside the palace to send the craftsmen back one by one.

at the same time.

Wu Yunwan and Murong Xueer were sitting in the courtyard, staring dumbly at the courtyard illuminated by the glazed lamp, which looked like daytime.

The two of them actually heard that the light would be on tonight. After all, they were there when the craftsmen were pulling wires in the yard these days, but neither of them realized that the light would be so bright, and that the light would actually be so bright. There was no need to use fire candles, which really shocked the two women.

Wu Yunwan said to herself: "How did he do it..." (End of Chapter)
